Abstract

An agonist for protein kinase C alone, a steroid alone, or a retinoic acid alone do not substantially increase expression of antigens on cancerous cells. However, expression of those antigens is substantially and synergistically increased upon administering a combination of an agonist of protein kinase C with a steroid or upon administering a combination of an agonist of protein kinase C with a retinoic acid. Particular useful combinations and compositions disclosed herein comprise a bryostatin compound and a steroid or a bryostatin compound and a retinoic acid. Even more useful combinations and compositions disclosed herein comprise Bryostatin-1 and dexamethasone, Bryostatin-1 and prednisolone, or Bryostatin-1 and tretinoin. Combinations and compositions of the present invention are particularly useful for treating cancer, for inhibiting growth of cancer cells, for increasing expression of antigens on cancer cells and for sensitizing those cells for therapies.

COMBINATIONS OF AGONISTS OF PROTEIN KINASE C WITH STEROIDS OR RETINOIC ACIDS FOR THE TREATMENT OF CANCER

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority benefit of the filing date of U.S. Provisional

Patent Application No. 62/805,064, filed on February 13, 2019, the disclosure of which application is herein incorporated by reference in its entirety.

FIELD OF THE INVENTION

[0002] This invention relates to novel compositions for use in methods for inducing expression of an antigen in a cancerous cell, for inhibiting the growth of a cancerous cell, and for treating proliferative diseases, more specifically, for treating hematologic cancers, such as leukemia.

BACKGROUND OF THE INVENTION

[0003] Antibody -based therapeutics provide highly targeted approaches for treating hematologic malignancies by specifically targeting therapeutic agents to cancerous cells that preferentially express a specific surface marker. Several antibody-based therapies including chimeric antigen receptor-T-cell (“CAR-T”) therapies, and therapies involving antibody drug conjugates (“ADCs”) and/or monoclonal antibody (“mAB”) have been developed for targeting a variety of markers across the spectrum of B-cell malignancies.

[0004] B-cell malignancies are characterized by the presence of aberrant proliferative cells resembling healthy cells at different stages of the continuum of B-cell development (Blanc et al, Clin Cancer Res (2011) 17(20):6448-58). Along the continuum of B-cell development surface markers like CD 19, CD20, and CD22 rise and increase in expression and these targets similarly are found on lymphoid malignancies. Antibody-based therapeutics targeting CD 19, CD20, and CD22 have been developed and are used to treat a wide range of lymphoid malignancies, e.g., CD19 CAR-T for ALL/DLBCL, CD20 mAB therapy for CLL/FL/DLBCL/MCL, and CD22 ADCs for ALL/HCL. Expression level of the target surface marker plays an important role in the effect of a given antibody -based therapeutic. [0005] The efficacy of Rituximab^®, an anti-CD20 antibody, has been shown to be affected by expression level of CD20 antigens on target cells, with increased expression of CD20 on target cells showing enhanced Rituximab^®-mediated toxicity (Al-zoobi el al, Int Immunol (2014) 26(8):451-65). Furthermore, downregulation of CD20 antigen expression occurs in subsets of CLL patients that develop resistance to Rituximab^® (Small et al. , Peer J (2013) l :e31; Hiraga et al., Blood (2009) 113(20):4885-93) and, similarly, relapsed multiple myeloma patients have been found to suppress expression of CD38 after treatment with anti- CD38 therapy (Ise et al., Clin Lymphoma Myeloma Leuk (2016) 16(5):e59-64). Conversely increasing the expression of the surface marker targets has been shown in vitro to increase the efficacy for antibody therapies for various B-cell malignancies across multiple targets including CD20, CD22, and CD38 (Al-zoobi et al., Int Immunol (2014) 26(8):451-65);

Biberacher et al., Haematologica (2012) 97(5):771-9; Nijhof et al., Leukemia (2015) 29(10):2039-49).

[0006] Thus, compounds that increase the expression of cell surface antigens on cancerous cells show promise in increasing the efficacy of antibody -based therapeutics for B- cell malignancies. The art, however, is devoid of such compounds, combination of compounds and compositions of compounds and, hence, there is a great need and unsatisfied demand in the art to provide such compounds, combinations, and compositions. Applicants’ invention and disclosure herein responds to that need and provide compounds, combinations, and compositions that substantially increases expression of CD 19, CD20, and CD22 antigens on the surface of cancerous cells obtained from CLL, ALL, MCL (see, FIG. 1) patients.

[0070] Throughout the present specification and the accompanying claims, the words

"comprise," "include," and“have” and variations thereof such as "comprises," "comprising," "includes," "including,"“has,” and“having” are to be interpreted inclusively. That is, these words are intended to convey the possible, however, not mandatory, inclusion of other elements or integers not specifically recited, where the context allows. The term "consisting essentially of means that the composition, method or structure may include additional ingredients, steps and/or parts, but only if the additional ingredients, steps and/or parts do not materially alter the basic and novel characteristics of the claimed composition, method or structure. No language in the specification should be construed as indicating any non- claimed element essential to the practice of the invention.

[0071] The terms "a" and "an" and "the" and similar referents used in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context.

[0072] The term "and/or" where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. For example, "A and/or B" is to be taken as specific disclosure of each of (i) A, (ii) B and (iii) A and B, just as if each is set out individually herein.

[0073] Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. Ranges may be expressed herein as from "about" (or "approximate") one particular value, and/or to "about" (or "approximate") another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about" or "approximate" it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as "about" that particular value in addition to the value itself. For example, if the value 10 is disclosed, then "about 10 is also disclosed. It is also understood that when a value is disclosed that is "less than or equal to the value" or "greater than or equal to the value" possible ranges between these values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value " 10" is disclosed the "less than or equal to 10 "as well as "greater than or equal to 10" is also disclosed.

[0074] All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. Further, all methods described herein and having more than one step can be performed by more than one person or entity. Thus, a person or an entity can perform step (a) of a method, another person or another entity can perform step (b) of the method, and a yet another person or a yet another entity can perform step (c) of the method, etc. The use of any and all examples, or exemplary language (e.g., "such as") provided herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed.

[0075] Units, prefixes, and symbols are denoted in their Systeme International de

Unites (SI) accepted form. Unless otherwise indicated, nucleic acids are written left to right in 5' to 3' orientation; amino acid sequences are written left to right in amino to carboxy orientation.

[0076] Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member may be referred to and claimed individually or in any combination with other members of the group or other elements found herein. It is anticipated that one or more members of a group may be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.

[0077] The headings used herein are for organizational purposes only and are not meant to be used to limit the scope of the description or the claims, which can be had by reference to the specification as a whole. Accordingly, the terms defined immediately below are more fully defined by reference to the specification in its entirety.

[0078] Illustrations are for the purpose of describing a preferred embodiment of the invention and are not intended to limit the invention thereto.

[0079] Unless defined otherwise, all technical and scientific terms used herein have the meaning commonly understood by a person skilled in the art to which this invention belongs. The following references provide one of skill with a general definition of many of the terms used in this invention: Singleton et al., Dictionary of Microbiology and Molecular Biology (2nd ed. 1994); The Cambridge Dictionary of Science and Technology (Walker ed., 1988); T he Glossary of Genetics, 5th Ed., R. Rieger et al. (eds.), Springer Verlag (1991); and Hale & Marham, The Harper Collins Dictionary of Biology (1991). As used herein, the following terms have the meanings ascribed to them unless specified otherwise.

[0080] In the following description, it is understood that relative terms such as“first,”

"second," "third," "fourth," and the like are words of convenience and are not to be construed as limiting terms. They are merely used to describe one element or a feature’s relationship to another element(s) or feature(s). It will be understood that the terms, such as "first,"

"second," "third," and "fourth," and the like may be used herein to describe various features and elements (including steps of a method), and that these features and elements should not be limited by these terms, unless the context clearly indicates otherwise. These terms may be used to distinguish one feature or element from another feature or element. It will be further understood that a first feature or a first element can be the same as a second feature or a second element. Also, a first feature or first element discussed herein could be termed a second feature or second element, and similarly, a second feature or second element described herein could be termed a first feature or first element without departing from the teachings of the present invention.

[0081] As used herein, the term "about" refers to a range of values of plus or minus

10% of a specified value. For example, the phrase "about 200" includes plus or minus 10% of 200, or from 180 to 220, unless clearly contradicted by context.

[0082] As used herein, the terms "to administer, " "administering," "administered" or grammatical equivalents thereof mean the actual physical introduction of a composition into or onto (as appropriate) a host or a cell. Any and all methods of introducing the composition into the host or cell are contemplated according to the invention; the method is not dependent on any particular means of introduction and is not to be so construed. Means of introduction, such as injecting, inhaling, ingesting, absorbing, implanting, and the like, are well-known to those skilled in the art, and also are exemplified herein.

[0083] As used herein, contacting in“combination,”“contacting a combination,” administration "in combination,"“administering a combination,” "co-administration" or grammatical equivalents thereof refer to both simultaneous and sequential contacting or both simultaneous and sequential administration of two or more compounds or two or more compositions. Concurrent or combined administration to a subject, as used herein, means that two or more compounds or two or more compositions are administered to a subject either (a) simultaneously, or (b) at different times during the course of a common treatment schedule. In the latter case, the two or more compounds or compositions are administered sufficiently close in time to achieve the intended effect. Concurrent or combined

administration, as used herein, also means that a composition comprising one or more agonists of protein kinase C, a composition comprising one or more steroid compounds, or a composition comprising one or more retinoic acid compounds can be administered in combination with a another composition comprising one or more therapeutic agents.

Concurrent or combined administration, as used herein, also means that a one or more agonists of protein kinase C, one or more steroid compounds, or one or more retinoic acid compounds can be administered in combination with one or more therapeutic agents.

[0084] The terms "agent" and "compound" are used interchangeably herein and mean any chemical compound, for example, a macromolecule or a small molecule disclosed herein. An agent can have a formula weight of less than about 100,000 grams per mole, less than about 50,000 grams per mole, less than about 10,000 grams per mole, less than 5,000 grams per mole, less than 1,000 grams per mole, or less than about 500 grams per mole. An agent can be naturally occurring (e.g., a herb or a nature product), synthetic, or both. Examples of macromolecules are proteins, protein complexes, and glycoproteins, nucleic acids, e.g., DNA, RNA and PNA (peptide nucleic acid). Examples of small molecules are peptides, peptidomimetics (e.g., peptoids), amino acids, amino acid analogs, polynucleotides, polynucleotide analogs, nucleotides, nucleotide analogs, organic or inorganic compounds, e.g., heteroorganic or organometallic compounds. An agent can be the only substance used in a method described herein. Alternatively, a collection of agents can be used either consecutively or concurrently in methods described herein. Likewise, an agent can be the only substance used in a composition or kit described herein. Alternatively, a collection of agents can be used in a combination, a composition, a kit or an article of manufacture as described herein.

[0085] As used herein, the term "agonist" refers to an agent that causes an increase in the expression or activity of a target gene or protein, respectively. An agonist can bind to and activate its cognate target in some fashion, which directly or indirectly brings about a physiological effect on the target gene or protein. Agonists include agents that, e.g., induce or activate the expression of a polypeptide of the invention or bind to, stimulate, increase, open, activate, facilitate, or enhance activation, sensitize or up-regulate the activity of a polypeptide of the invention. The terms "protein kinase C agonist,"“PKC agonist,” or agonist of protein kinase C (PKC),” as used herein, refers to a compound that causes activation of protein kinase C. Such agonists include nucleic acids such as siRNA, antisense RNA, and ribozymes that increase or activate the expression of protein kinase C as well as naturally occurring and synthetic compounds and agents, small chemical molecules and the like. Preferred protein kinase C agonists are the compounds described herein. For example, an activation or increased activity of protein kinase C by a disclosed composition can be determined by assaying the activity of protein kinase C in the presence of the composition and comparing it to the activity of protein kinase C in the absence of the composition. In this example, if the activity of protein kinase C is increased in the presence of the composition as compared to the activity of protein kinase C in the absence of the composition, the composition can be said to increase the activity of protein kinase C. More specifically, samples or assays comprising e.g., a protein kinase C polypeptide that are treated with an agonist (or a potential agonist) are compared to control samples without the agonist to examine the extent of the effect. Control samples (untreated with agonists) are assigned a relative activity value of 100%. Activation of the protein kinase C polypeptide is achieved when the level or activity value relative to a control is increased by about 20%, by about 30%, by about 40%, by about 50%, by about 60%, by about 70%, by about 80%, by about 90, by about 100%, by about 150%, by about 200%, by about 250%, by about 300%, by about 350%, by about 400%, by about 500%, by about 750%, by about 1000% or more. Further, activation of the protein kinase C polypeptide is achieved when the level or activity value relative to a control is increased by at least about 20%, by at least about 30%, by at least about 40%, by at least about 50%, by at least about 60%, by at least about 70%, by at least about 80%, by at least about 90, by at least about 100%, by at least about 150%, by at least about 200%, by at least about 250%, by at least about 300%, by at least about 350%, by at least about 400%, by at least about 500%, by at least about 750%, by at least about 1000% or more. Assays for agonists of protein kinase C activity are known in the art.

[0086] As used herein, the abbreviation "ALL" refers to acute lymphocytic leukemia and includes B-cell ALL (B-ALL) and T-cell ALL (T-ALL).

[0087] As used herein, the abbreviation "AML" refers to acute myelocytic leukemia and includes B-cell AML (B-AML) and T-cell AML (T-AML). [0088] As used herein, the term "antigen" refers to a molecule or composition of matter, which induces an immune response in an animal and which interacts specifically with antigen-recognizing components of an animal's immune system. Included within the term are endogenous antigens (self-antigens, i.e., antigens expressed by an isolated animal cell or by a cell within an animal) and exogenous antigens. An exogenous antigen refers to a substance that, upon introduction into a vertebrate animal, stimulates the production of antibodies.

[0089] As used herein, an "assay" refers to a test performed on a sample or a component of a sample. An assay can test for the presence of a component, the amount or concentration of a component, the composition of a component, the activity of a component, etc. Assays that can be performed in conjunction with the compositions and methods of the present invention include, but are not limited to, immunocytochemical assays, flow cytometry, fluorescence-activated cell sorting (FACS), interphase FISH (fluorescence in situ hybridization), karyotyping, immunological assays, biochemical assays, binding assays, cellular assays, genetic assays, gene expression assays and protein expression assays. A preferred component assayed for is an antigen, preferably, a lymphocyte antigen, more preferably, a B-lymphocyte antigen.

[0090] As used herein, the term "biologically active" when referring to an agent is art- recognized and refers to a form of an agent that allows for it, or a portion of the amount of agent administered, to be absorbed by, incorporated to, or otherwise physiologically available to a subject or patient to whom it is administered.

[0091] As used herein, "biological sample" means a sample of biological tissue, cells or fluid that contains nucleic acids or polypeptides. Such samples are typically from humans, but include tissues, cells or fluids isolated from non-human primates, or rodents, e.g., mice, and rats. Biological samples may also include sections of tissues such as biopsy and autopsy samples, frozen sections taken for histological purposes, cerebral spinal fluid, blood, plasma, serum, sputum, stool, tears, mucus, hair, skin, etc. Biological samples also include explants and primary and/or transformed cell cultures derived from patient tissues. A "biological sample" also refers to a cell or population of cells or a quantity of tissue or fluid from an animal. Most often, the biological sample has been removed from an animal, but the term "biological sample" can also refer to cells or tissue analyzed in vivo, i.e., without removal from the animal. Typically, a "biological sample" will contain cells from the animal, but the term can also refer to non-cellular biological material, such as non-cellular fractions of blood, serum, saliva, cerebral spinal fluid or urine, that can be used to measure expression level of a polynucleotide or polypeptide. Numerous types of biological samples can be used in the present invention, including, but not limited to, a tissue biopsy or a blood sample. As used herein, a "tissue biopsy" refers to an amount of tissue, such as a lung tissue, removed from an animal, preferably a human, for diagnostic analysis. "Tissue biopsy" can refer to any type of biopsy, such as needle biopsy, fine needle biopsy, surgical biopsy, etc. As used herein, "providing a biological sample" means to obtain a biological sample for use in a method described herein. Most often, this will be done by removing a sample of tissue, cells, or fluid from a subject, but can also be accomplished by using previously isolated tissue(s), cell(s) or fluid(s) (e.g., isolated by another person, at another time, and/or for another purpose), or by performing a method of the invention in vivo. Archival tissues, cells or fluids having treatment or outcome history, will be particularly useful.

[0092] As used herein, the term "B-lymphocyte cell, "B-lymphocyte," or, simply "B- cell," refers to a lymphocyte cell that is produced in the bone marrow, produces

immunoglobulins and is involved in the production of antibodies in the humoral immune response. A B-lymphocyte cell includes a B stem cell, a pro-B cell, a pre-B cell, a naive B cell, an activated B cell, a memory GC B cell, a late plasmablast cell and a plasma cell.

[0093] As used herein, the terms "B-lymphocyte antigen" "antigen in a B-lymphocyte cell" or "antigen on the cell surface of a B-lymphocyte cell" refer to an antigen expressed in a B-lymphocyte cell. A preferred B-lymphocyte antigen is an antigen located on the cell surface of a B-lymphocyte cell, which may also be referred to as B-lymphocyte surface marker. Exemplary B-lymphocyte cell surface markers include, but are not limited to, CD 10, CD 19, CD20, CD21, CD22, CD23, CD24, CD37, CD53, CD72, CD73, CD74, CDw75, CDw76, CD77, CDw78, CD79a, CD79b, CD80, CD81, CD82, CD83, CDw84, CD85 and CD86 leukocyte surface markers. A B-lymphocyte surface marker of particular interest is preferentially expressed on B-cells compared to other non-B-cell tissues of a mammal and may be expressed on both precursor B-cells and mature B-cells. In some embodiments of the present invention, a B-cell surface marker is one, like CD20 or CD 19, which is found on B- cells throughout differentiation of the lineage from the stem cell stage up to a point just prior to terminal differentiation into plasma cells. Preferred B-cell surface markers herein are CD 19 and CD20. [0094] As used herein, the term "cancer" refers to a proliferative disease. A preferred cancer is a hematopoietic cancer.

[0095] As used herein, the term "cancerous cell" refers to a cell that exhibits deregulated growth and, in most cases, has lost at least one of its differentiated properties, such as, but not limited to, characteristic morphology, non-migratory behavior, cell-cell interaction and cell-signaling behavior, protein expression and secretion pattern, and the like.

[0096] As used herein, a cancer is "responsive" to a therapeutic agent if its rate of growth is inhibited as a result of contact with the therapeutic agent, compared to its growth in the absence of contact with the therapeutic agent. Growth of a cancer can be measured in a variety of ways, for instance, the size of a tumor, the number of tumor cells in a sample, or the expression of tumor markers appropriate for that tumor type may be measured. Still further, measures of responsiveness can be assessed using additional criteria beyond growth size of a tumor, including patient quality of life, degree of metastases, etc. In addition, clinical prognostic markers and variables can be assessed (e.g., M protein in myeloma, PSA levels in prostate cancer) in applicable situations. Likewise, a cancer is "non-responsive" to a therapeutic agent if its rate of growth is not inhibited, or inhibited to a very low degree, as a result of contact with the therapeutic agent when compared to its growth in the absence of contact with the therapeutic agent. As stated above, growth of a cancer can be measured in a variety of ways, for instance, the size of a tumor, the number of tumor cells in a sample, or the expression of tumor markers appropriate for that tumor type may be measured.

[00102] As used herein, the term "contacting" or grammatical equivalents is meant to refer to an instance of exposure of at least one substance to another substance. For example, contacting can include contacting a substance, such as a cell, to a composition or therapeutic agent as described herein. A cell can be contacted with the composition or therapeutic agent, for example, by adding the composition or therapeutic agent to the culture medium (e.g., by continuous infusion, by bolus delivery, or by changing the medium to a medium that contains the composition or therapeutic agent) or by adding the composition or therapeutic agent to an extracellular fluid in vivo (e.g., by local delivery, systemic delivery, intravenous injection, bolus delivery, or continuous infusion). The duration of contact with a cell or group of cells may be determined by one of ordinary skill in the art by the time the composition or therapeutic agent is present at physiologically effective levels or at presumed physiologically effective levels in the medium or extracellular fluid bathing the cell. In the present invention, for example, a lymphocyte cell expressing a lymphocyte antigen or a B-lymphocyte cell expressing a B-lymphocyte antigen is contacted with a composition or therapeutic agent in an effective amount. As one of ordinary skill in the art will appreciate, the term“contacting” is used herein interchangeably with the following: combined with, added to, mixed with, passed over, incubated with, flowed over, placed in direct physical association with another substance, and the like.

[00103] As used herein, contacting "in combination" refers to both simultaneous and sequential exposure of two or more substances to another substance. Concurrent or combined contacting of a cell, as used herein, means that two or more agents are contacted to a cell either (a) simultaneously, or (b) at different times during the course of a common schedule.

In the latter case, the two or more agents are contacted to the cell sufficiently close in time to achieve the intended effect. Concurrent or combined contacting of a cell, as used herein, also means that a first composition comprising one or more bryostatin compounds and one or more dexamethasone compounds can be contacted to a cell in combination with a second composition comprising one or more therapeutic agents. [00104] As used herein, if, for example, a biological sample is obtained from a patient having a disease, the terms "control" or "control sample," refer to a biological sample from a healthy patient or a biological sample from a patient not having the disease.

[00105] As used herein, the term "cytotoxic agent" refers to a substance that inhibits or prevents the function of a cell and/or causes destruction of a cell.

A "functional derivative" refers to a derivative of a compound that substantially functions as the compound from which it was derived. A "physiologically functional derivative" refers to any pharmaceutically acceptable derivative of a compound of the present invention, for example an ester or an amide thereof, and includes any pharmaceutically acceptable salt, ester, or salt of such ester of a compound which, upon administration to a mammal, such as a human, is capable of providing (directly or indirectly) a compound as described herein or an active metabolite or residue thereof. It will be appreciated by those skilled in the art that compounds described herein may be modified to provide physiologically functional derivatives thereof at any of the functional groups in those compounds, and that the compounds described herein may be so modified at more than one position. [00108] Synonyms of the term "determining" are contemplated within the scope of the present invention and include, but are not limited to, detecting, measuring, assaying, or testing for the presence, absence, amount or concentration of a nucleic acid, a polypeptide, a molecule, a label, or a small molecule of the invention and the like.

[00112] As used herein, the terms "disorder", "disease" or "pathological condition" are used inclusively and refer to any deviation from the normal structure or function of any part, organ or system of the body (or any combination thereof). A specific disease is manifested by characteristic symptoms and signs, including biological, chemical and physical changes, and is often associated with a variety of other factors including, but not limited to, demographic, environmental, employment, genetic and medically historical factors. Certain characteristic signs, symptoms, and related factors can be quantitated through a variety of methods to yield important diagnostic information.

Amelioration of a symptom of a particular condition by administration of a pharmaceutical composition described herein refers to any lessening, whether permanent or temporary, lasting or transit that can be associated with the administration of the pharmaceutical composition. As one of ordinary skill in the art will appreciate, with respect to "effective amount," "effective dose," "sufficient amount," "amount effective to," "therapeutically effective amount," of a pharmaceutical composition, the dosing range varies with the pharmaceutical composition used, the route of administration and the potency of the particular pharmaceutical composition. An "effective amount" can be administered in vivo, ex vivo, and in vitro.

[00118] As used herein, the terms "inhibition," "inhibiting," "inhibits" or grammatical equivalents thereof means to reduce an activity as compared to a control (e.g., activity or parameter in the absence of such inhibition). It is understood that inhibition can mean a slight reduction in activity to the complete ablation of all activity.

[00119] As used herein, the terms "inhibiting the growth of a cell," "inhibiting the growth of a population of cells" or grammatical equivalents thereof refer to inhibiting cell division and may include destruction of the cell.

The terms also refer to inhibiting an increase in cellular volume of a cell or inhibiting an increase in cell size of a cell.

[00120] As used herein, "in vitro" means outside the body of the organism from which a cell or cells is obtained or from which a cell line is isolated. Cell culture, or culture, typically refers to the maintenance of cells in an artificial, in vitro environment, or the maintenance of cells in an external, ex vivo environment (i.e., outside of an organism), and can include the cultivation of individual cells and tissues. Certain cell culture systems described herein may be an ex vivo environment and/or an in vitro environment.

[00121] As used herein, "in vivo " means within the body of the organism from which a cell or cells is obtained or from which a cell line is isolated.

[00122] As used herein, the term "isomer" refers to a compound that has the same molecular formula as another compound, but differs therefrom in the nature or sequence of bonding of their atoms or in the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed "stereoisomers." "Stereoisomer" and "stereoisomers" refer to compounds that exist in different stereoisomeric forms if they possess one or more asymmetric centers or a double bond with asymmetric substitution and, therefore, can be produced as individual stereoisomers or as mixtures. Stereoisomers include enantiomers and diastereomers. Stereoisomers that are not mirror images of one another are termed "diastereomers" and those that are non-superimposable mirror images of each other are termed "enantiomers." When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (-)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a "racemic mixture." Unless otherwise indicated, the description of compounds herein is intended to include individual stereoisomers as well as mixtures. Methods for determination of stereochemistry and separation of stereoisomers are well-known in the art (see, discussion in Chapter 4 of Advanced Organic Chemistry, 4th edition J. March, John Wiley and Sons, New York, 1992).

[00138] As used herein, the term "prodrug" refers to a compound, which is a drug precursor and which, following administration and absorption, releases the drug in vivo via some metabolic process. (See, e.g., Wihnan, " Prodrugs in Cancer Chemotherapy "

Biochemical Society Transactions, 14, pp. 375-382, 615th Meeting Belfast (1986) and Stella et al., " Prodrugs : A Chemical Approach to Targeted Drug Delivery," Directed Drug

Delivery, Borchardt et al, (ed.), pp. 247-267, Humana Press (1985). Prodrugs of compounds described herein include, but are not limited to, e.g., phosphate-containing prodrugs, thiophosphate-containing prodrugs, sulfate-containing prodrugs, peptide-containing prodrugs, D-amino acid-modified prodrugs, glycosylated prodrugs, 3-lactam-containing prodrugs, optionally substituted phenoxyacetamide-containing prodrugs or optionally substituted phenylacetamide-containing prodrugs, 5 fluorocytosine and other 5-fluorouridine prodrugs. Typically, a "prodrug" as used in this application when referring to a precursor or derivative form of a pharmaceutically active substance is less cytotoxic to tumor cells compared to the parent drug and is capable of being enzymatically activated or converted into the more active parent form. [00139] As used herein, the term "salt" refers to a salt of a compound which may be prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. When compounds described herein contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds described herein contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric,

monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see. for example, Berge et al., 1977, " Pharmaceutical Salts ", Journal of Pharmaceutical Science, 66: 1-19). Some specific compounds described herein may contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts. A preferred salt is a pharmaceutically acceptable salt. The neutral forms of a compound may be regenerated by contacting the salt with a base or acid and isolating the parent compound in a conventional manner. The parent form of the compound may differ from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of the present invention.

[00140] As used herein, the term "same" means of the same identity.

[00141] As used herein, the terms "selectively reactive," "selectively binding to,"

"specific reactive," "specifically binding to," or grammatical equivalents thereof refer, with respect to an antigen, to the preferential association of a binding partner (e.g., an antibody, and the like), in whole or part, with a cell or tissue bearing that antigen and not to cells or tissues lacking that antigen. It is, of course, recognized that a certain degree of non-specific interaction may occur between a molecule and a non-target cell or tissue. Nevertheless, selective reactivity, may be distinguished as mediated through specific recognition of the antigen. Although selectively reactive antibodies (or other binding partners) bind an antigen, they may do so with low affinity. On the other hand, specific binding results in a much stronger association between the antibody (or other binding partners) and cells bearing the antigen than between the bound antibody (or other binding partners) and cells lacking the antigen. Specific binding typically results in greater than 2 fold, preferably, greater than 5 fold, more preferably, greater than 10 fold, and, most preferably, greater than 100-fold increase in amount of bound antibody (or other binding partners), per unit time, to a cell or tissue bearing a target antigen as compared to a cell or tissue lacking the target antigen.

Specific binding to a protein under such conditions requires an antibody (or other binding partner) that is selected for its specificity for a particular protein. A variety of immunoassay formats are appropriate for selecting antibodies specifically immunoreactive with a particular protein. For example, solid-phase ELISA immunoassays are routinely used to select monoclonal antibodies (or other binding partners) specifically immunoreactive with a protein. See, Harlow & Lane, ANTIBODIES, A LABORATORY MANUAL, Cold Spring Harbor Publications, New York (1988), for a description of immunoassay formats and conditions that can be used to determine specific immunoreactivity.

In many embodiments, such small molecules do not include a peptide bond or a phosphodiester bond. For example, they can be non-polymeric. In some embodiments, a small molecule has a molecular weight of at least about 50, at least about 100, at least about 200, or at least about 400 Dalton. A preferred small molecule is dexamethasone having a molecular weight of about 392 g/mol. Another preferred small molecule is bryostatin having a molecular weight of about 905 g/mol.

[00143] As used herein, the terms "subject," "host," "individual," and "patient," are used interchangeably and refer to a mammal, including, but not limited to, murines, simians, felines, canines, equines, bovines, mammalian farm animals, mammalian sport animals, and mammalian pets and humans. Preferred is a human. As used herein, "subject" or "patient" to be treated for a pathological condition, disorder, or disease by a subject method means either a human or non-human animal in need of treatment for a pathological condition, disorder, or disease. Subjects include, males and females of any age group (infant, child, adolescent, young adult, middle-aged adult, or senior adult).

[00144] As used herein, the terms "synergism," "synergistic," "synergy,"

"synergizing," "synergistically," or grammatical equivalents thereof mean an interaction of two or more agents such that the effect when combined is greater than the predicted effect based on the response of each agent applied separately. A therapeutic synergism means a therapeutic effect achieved with a tolerated regimen of the combined agents that exceeds the optimal effect achieved at any tolerated dose of monotherapy. A synergistic effect can be about two-fold, about three-fold, about five-fold, about ten-fold or more when compared to the additive effect of the individual agents. Synergy, synergism or synergistic effects of a combination of agents can be determined as described in Ting-Chao Chou,“ Theoretical Basis, Experimental Design, and Computerized Simulation of Synergism and Antagonism in Drug Combination Studies”, Pharmacol. Rev. (2006) 58:621-681, which is incorporated herewith by reference in its entirety. A determination of a synergistic interaction between a compound or a pharmaceutically acceptable salt thereof and one or more agents may be based on the results obtained from assays described herein. The results of those assays can be analyzed, e.g., using the Chou and Talalay combination method and Dose-Effect Analysis with CalcuSyn software in order to obtain a Combination Index (Chou and Talalay, Adv Enzyme Regul (1984) 22:27-55). The combinations of compounds provided herein can be evaluated in several assay systems, and the data can be analyzed utilizing a standard program for quantifying synergism, additivism, and antagonism among agents. A preferred program is that described by Chou and Talalay, in " New Avenues in Developmental Cancer

Chemotherapy ," Academic Press, 1987, Chapter 2. A combination therapy may provide "synergy" and prove "synergistic," i.e., the effect achieved when the active ingredients used together is greater than the sum of the effects that results from using the compounds separately. A synergistic effect may be attained when the active ingredients are: (i) co formulated and administered or delivered simultaneously in a combined, unit dosage formulation; (ii) delivered by alternation or in parallel as separate formulations; or (iii) by some other regimen. When delivered in alternation therapy, a synergistic effect may be attained when the compounds are administered or delivered sequentially, e.g., by different injections in separate syringes. In general, during alternation therapy, an effective dosage of each active ingredient is administered sequentially, i.e., serially, whereas in combination therapy, effective dosages of two or more active ingredients are administered together.

[00145] As used herein, the term "targeting moiety" refers to the portion of an immunotoxin intended to target a toxin to a cell of interest. Typically, the targeting moiety is an antibody, or a fragment of an antibody that retains antigen recognition capability, such as a scFv, a dsFv, an Fab, or an F(ab’)2, but it can also be, for example, a cytokine (e.g., IL-13), or other protein (such as a transferrin) that binds a specific antigen or receptor, preferably an antigen or a receptor on a cell surface.

[00146] As used herein, the term "targeted toxin" refers to a cytotoxic agent, which is covalently linked to targeting moiety and targeted to a desired cell by the targeting moiety, which binds to a specific receptor or antigen present on the surface of such cell.

[00147] As used herein, the terms "T-lymphocyte cell," "T-lymphocyte," or simply, "T-cell” refer to any lymphocyte that matures in the thymus and has the ability to recognize specific peptide antigens, or specific peptide antigens complexed with a major

histocompatibility complex protein (MHC), through the receptors on its cell surface.

[00148] As used herein, the term "therapeutic agent" refers to any number of compounds that is administered to a patient to induce a desired therapeutic effect in a patient. A therapeutic effect intended is, for example, the killing of a cancer cell. Another therapeutic effect is to treat a patient.

[00149] As used herein, the terms "treat," "treating," and "treatment" or grammatical equivalents thereof refer to both therapeutic treatment and prophylactic or preventative measures. Those in need of treatment include subjects already afflicted with a pathological condition, disorder, or disease as well as those in which a pathological condition, disorder, or disease is to be prevented. Hence, a subject may have been diagnosed as having a pathological condition, disorder, or disease or may be predisposed or susceptible to a pathological condition, disorder, or disease. As such, the terms include: (1) preventing a pathological condition, disorder, or disease, i.e. causing the clinical symptoms of the pathological condition, disorder, or disease not to develop in a subject that may be predisposed to the pathological condition, disorder, or disease but does not yet experience any symptoms of the pathological condition, disorder, or disease; (2) inhibiting the pathological condition, disorder, or disease, i.e. arresting or reducing the development of the pathological condition, disorder, or disease or its clinical symptoms; or (3) relieving the pathological condition, disorder, or disease, i.e. causing regression of the pathological condition, disorder, or disease or its clinical symptoms. These terms encompass also prophylaxis, therapy and cure. Treatment means any manner in which the symptoms of a pathological condition, disorder, or disease are ameliorated or otherwise beneficially altered. Preferably, the subject in need of such treatment is a mammal, more preferable a human.

[00274] Preferred therapeutic agents include, but are not limited to, antibodies and immunotoxins.

1. Antibodies

[00275] In some embodiments of the present invention, a therapeutic agent is an antibody. Various antibodies can be used to prepare a composition of the present invention or to use such composition in a method of the present invention. In some embodiments of the present invention, an antibody is selected from the group consisting of an antibody mediating antibody-dependent cellular cytotoxicity, a monoclonal antibody, a humanized antibody, a chimeric antibody, a bi-specific antibody, an ADC, an antibody fragment, and a recombinant antibody. i. Antibody Mediating Antibody-Dependent Cellular

Cytotoxicity

[00276] In some embodiments of the present invention, an antibody is an antibody for mediating antibody-dependent cellular cytotoxicity (ADCC), also called antibody-dependent cell-mediated cytotoxicity. ADCC is an immune mechanism through which Fc receptor bearing effector cells (e.g., natural killer (NK) cells) can recognize and kill antibody-coated target cells expressing tumor antigens on their surface. Numerous associations between ADCC activity, Fc receptor polymorphisms, and clinical outcomes have been observed in both the settings of vaccination and monoclonal antibody therapy. ii. Monoclonal Antibody

[00277] In some embodiments of the present invention, an antibody is a monoclonal antibody.

1. Ofatumumab^®

[00278] In some embodiments of the present invention, a monoclonal antibody is Ofatumumab^®. Ofatumumab^® is also known as ARZERRA^®. Ofatumumab^® is an anti- CD20 IgGlK human monoclonal antibody. The candidate targets the same antigen as rituximab, but Ofatumumab^® binds a novel, membrane-proximal epitope, and dissociates from its target at a slower rate compared to rituximab (Zhang, MAbs (2009) 1(4):326-331). It is manufactured by Novartis and used to treat: (i) in combination with chlorambucil, for the treatment of previously untreated patients with chronic lymphocytic leukemia (CLL) for whom fludarabine-based therapy is considered inappropriate, (ii) in combination with fludarabine and cyclophosphamide for the treatment of patients with relapsed CLL, (iii) for extended treatment of patients who are in complete or partial response after at least 2 lines of therapy for recurrent or progressive CLL, and (iv) for the treatment of patients with CLL refractory to fludarabine and alemtuzumab. iii. Humanized Antibody

[00279] In some embodiments of the present invention, an antibody is a humanized antibody. iv. Chimeric Antibody

[00280] In some embodiments of the present invention, an antibody is a chimeric antibody.

1. Rituximab^®

[00281] In some embodiments of the present invention, a chimeric antibody is Rituximab^®. Rituximab^®, a human-mouse chimeric monoclonal antibody (mAh) that targets CD20 and inducers apoptosis in targeted cells. Rituximab^® is a prescription medicine made by Roche and is used to treat (i) Low-grade or follicular CD20-positive non-Hodgkin’s lymphoma as a single-agent therapy in patients whose disease recurred or did not respond to initial treatment, (ii) Follicular CD20-positive non-Hodgkin’s lymphoma as an initial treatment with chemotherapy, and in patients whose initial treatment was successful, as a single-agent follow-up therapy, (iii) Low-grade CD20-positive non-Hodgkin’s lymphoma as a single-agent follow-up therapy for patients who did not progress on initial treatment with CVP chemotherapy, (iv) CD20-positive diffuse large B-cell non-Hodgkin’s lymphoma as an initial treatment in combination with CHOP chemotherapy, and (v) CD20-positive chronic lymphocytic leukemia in combination with FC chemotherapy as an initial treatment or as a treatment after disease has recurred.

[00282] Although the majority of B cell malignancies express CD20 antigen (see. FIG. 1), only about 50% of patients will respond to single-agent rituximab. The available data suggests that a decrease CD20 expression could account for the lack of response observed in some patients treated with rituximab. (Wojciechoeski et al., J Immunol (2005) 174:7859- 7868). While Wojciechoeski and co-workers demonstrated that Bryostatin-1 enhanced the expression of both CD20 mRNA and protein, and thus, rendered the cells more susceptible to Rituximab, they also found that the effect of Bryostatin-1 on CD20 expression was insensitive to dexamethasone. (Wojciechoeski et al., J Immunol (2005) 174:7859-7868). As one of ordinary skill in the art will appreciate in view of the data reported by Wojciechoeski and co-workers, the findings reported by Applicants herein that Bryostatin-1 and dexamethasone synergistically increase expression of CC20 antigen is unexpected and surprising. v. Antibody Fragment

[00283] In some embodiments of the present invention, an antibody is an antibody fragment. vi. Recombinant Antibody

[00284] In some embodiments of the present invention, an antibody is a recombinant antibody. vii. Bi-specific Antibody

[00285] In some embodiments of the present invention, an antibody is a bi-specific antibody.

2. Immunotoxins

[00286] In some embodiments of the present invention, a therapeutic agent is an immunotoxin. Various immunotoxins can be used to prepare a composition of the present invention or to use such composition in a method of the present invention. An immunotoxin typically comprises two parts - a targeting moiety and a cytotoxic moiety. The targeting moiety facilitates the transfer and internalization of the immunotoxin into a cell, e.g., a cancerous cell. The cytotoxic moiety kills the cell, typically by enzymatically inhibiting protein synthesis.

[00287] In some embodiments of the present invention, an immunotoxin is selected from the group consisting of a recombinant immunotoxin, a PE-based immunotoxin, a DT- based immunotoxin, and combinations thereof. Typically, cells are exposed to or contacted with an effective amount of a composition comprising an immunotoxin wherein the contacting results in killing of the cells. Typically, when cells are exposed to or contacted with an effective amount of the composition in vivo, the contacting results in killing of the cells and treatment of the subject.

[00288] In some embodiments of the present invention, an immunotoxin is a recombinant immunotoxin. Recombinant immunotoxins (RITs) are proteins that contain a toxin fused to an antibody (e.g., ADCs) or small molecules and are constructed by the genetic engineering technique. RITs can bind to and be internalized by cells and kill cancerous or non-cancerous cells by inhibiting protein synthesis. A wide variety of RITs have been tested against different cancers in cell culture, xenograft models, and human patients during the past several decades. RITs have shown activity in therapy of several kinds of cancers, but different levels of side effects, mainly related to vascular leak syndrome, were also observed in the treated patients. High immunogenicity of RITs may limit their long-term or repeat applications in clinical cases. Recent advances in the design of immunotoxins, such as humanization of antibody fragment, PEGylation, and modification of human B- and T-cell epitopes, are overcoming the above mentioned problems, which predict the use of these immunotoxins as a potential therapeutic method to treat cancer patient (See. Li el al, Onco Targets Ther 2017, 10:3645-3665; incorporated hereby and herein in its entirety for all purposes).

[00289] In some embodiments of the present invention, an immunotoxin is a PE-based immunotoxin. A PE-based immunotoxin comprises a Pseudomonas exotoxin (PE). PE is a single-chain protein, consisting of 613 amino acids in length, which is further composed of 3 functional domains. Domain la (amino acids 1-252) is the binding domain, domain II (amino acids 253-364) mediates translocating the toxin to the cytosol, and domain III (amino acids 400-613) contains the ADP-ribosylating enzyme that inactivates EF-2 in the cytosol. (See.

Li et al., Onco Targets Ther 2017, 10:3645-3665).

[00290] In some embodiments of the present invention, an immunotoxin is a DT-based immunotoxin. A DT-based immunotoxin comprises a Diphtheria toxin (DT). Full-length 535-amino acid DT is a single-chain protein containing an enzymatic A domain (amino acids 1-193) and a binding B domain (amino acids 482-535) A translocation or transmembrane (T) domain is located in the center of the molecule. (See, Li el al, Onco Targets Ther 2017, 10:3645-3665).

2. Therapeutic Effective Amount And Dosing

[00329] In some embodiments of the present invention, a pharmaceutical combination or a pharmaceutical composition or medicament is administered to a subject, preferably a human, at a therapeutically effective dose to prevent, treat, or control a condition or disease as described herein, such as cancer. The pharmaceutical combination, pharmaceutical composition or medicament is administered to a subject in an amount sufficient to elicit an effective therapeutic response in the subject. An effective therapeutic response is a response that at least partially arrests or slows the symptoms or complications of the condition or disease. An amount adequate to accomplish this is defined as "therapeutically effective dose."

[00330] As one of ordinary skill in the art will appreciate, the dosage of active compounds, combinations and compositions of the present invention administered is dependent on the species of warm-blooded animal (mammal), the body weight, age, individual condition, surface area of the area to be treated and on the form of administration. The size of the dose also will be determined by the existence, nature, and extent of any adverse effects that accompany the administration of a particular small molecule compound in a particular subject. A unit dosage for oral administration to a mammal of about 50 to 70 kg may contain between about 5 and 500 mg of the active ingredient. Typically, a dosage of the active compounds of the present invention, is a dosage that is sufficient to achieve the desired effect. Optimal dosing schedules can be calculated from measurements of compound accumulation in the body of a subject. In general, dosage may be given once or more daily, weekly, or monthly. Persons of ordinary skill in the art can easily determine optimum dosages, dosing methodologies and repetition rates.

[00331] In some embodiments of the present invention, a pharmaceutical combination or a pharmaceutical composition or a medicament comprising a compound or compounds of the present invention is administered in a daily dose in the range from about 0.1 mg of each compound per kg of subject weight (0.1 mg/kg) to about 1 g/kg for multiple days. In another embodiment, the daily dose is a dose in the range of about 5 mg/kg to about 500 mg/kg. In yet another embodiment, the daily dose is about 10 mg/kg to about 250 mg/kg. In another embodiment, the daily dose is about 25 mg/kg to about 150 mg/kg. A preferred dose is about 10 mg/kg. The daily dose can be administered once per day or divided into subdoses and administered in multiple doses, e.g., twice, three times, or four times per day. However, as will be appreciated by a skilled artisan, a small molecule compound of the present invention, an agonist of protein kinase C, a bryostatin compound, Bryostatin-1, a steroid, a

glucocorticoid, a dexamethasone compound, dexamethasone, prednisolone, a retinoic acid, tretinoin, or a therapeutic agent may be administered in different amounts and at different times.

[00332] To achieve a desired therapeutic effect, compounds, combinations, and compositions of the present invention (i.e., a small molecule compound of the present invention, an agonist of protein kinase C, a bryostatin compound, Bryostatin-1, a steroid, a glucocorticoid, a dexamethasone compound, dexamethasone, prednisolone, a retinoic acid, tretinoin, or a therapeutic agent) may be administered for multiple days at the therapeutically effective daily dose. Thus, therapeutically effective administration of compounds, combinations, and compositions of the present invention to treat a condition or disease described herein in a subject requires periodic (e.g., daily) administration that continues for a period ranging from three days to two weeks or longer. Typically, compounds, combinations, or compositions will be administered for at least three consecutive days, often for at least five consecutive days, more often for at least ten, and sometimes for 20, 30, 40 or more consecutive days. While consecutive daily doses are a preferred route to achieve a therapeutically effective dose, a therapeutically beneficial effect can be achieved even if the compounds are not administered daily, so long as the administration is repeated frequently enough to maintain a therapeutically effective concentration of the compounds in the subject. For example, one can administer the compounds, combinations or compositions every other day, every third day, or, if higher dose ranges are employed and tolerated by the subject, once a week. A preferred dosing schedule, for example, is administering daily for a week, one week off and repeating this cycle dosing schedule for 3-4 cycles.

[00333] Optimum dosages, toxicity, and therapeutic efficacy of such compounds, combinations and compositions may vary depending on the relative potency of individual compounds and can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, for example, by determining the LD50 (the dose lethal to 50% of the population) and the ED₅₀ (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and can be expressed as the ratio, LD₅₀/ED₅₀. Compounds, combinations and compositions that exhibit large therapeutic indices are preferred. While compounds, combinations and compositions that exhibit toxic side effects can be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue to minimize potential damage to normal cells and, thereby, reduce side effects. Without being bound by theory, some compounds, combinations and compositions described herein, such as Bryostatin-1, dexamethasone and certain antibodies (e.g., Rituximab^®, Ofatumumab^®) are FDA-approved compounds and thus, are expected to have low, if any toxicity or side effects.

[00334] Data obtained from, for example, cell culture assays and animal studies can be used to formulate a dosage range for use in humans. The dosage of such small molecule compounds lies preferably within a range of circulating concentrations that include the ED₅₀ with little or no toxicity. The dosage can vary within this range depending upon the dosage form employed and the route of administration. For any compounds, combinations, or compositions used in the methods of the invention, the therapeutically effective dose can be estimated initially from cell culture assays. A dose can be formulated in animal models to achieve a circulating plasma concentration range that includes the IC₅₀ (the concentration of the test compound that achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma can be measured, for example, by high performance liquid chromatography (HPLC). In general, the dose equivalent of compounds is from about 1 ng/kg to 100 mg/kg for a typical subject.

III. EXAMPLES

[00470] The below examples are meant to illustrate specific embodiments of the methods and compositions described herein and should not be construed as limiting the scope of the invention in any way.

Example A. Materials And General Procedures

1. Patient Samples

[00471] Peripheral blood or bone marrow samples from patients with CLL, MCL, or B-ALL were assigned a sample ID upon receipt. The sample IDs consisted of (1) three digit patient identifier (2) a three letter indication identifier (ALL, CLL, or MCL) and (3) a sampling number for that patient (first sample received from that patient given sampling number of 1 and subsequent samples from same patient would receive the next increment). For example, the exemplary sample with ID 674CLL1, corresponds to the 674th sample received at Applicant’s facility (“674”), the patient had been diagnosed with CLL (“CLL”) and that sample was the first sample received from that patient (“1”). Thus, e.g., 674CLL1 and 674CLL2 refer to distinct samples from the same patient, and may include different cells/ tissue or the same cells/ tissue serially sampled.

2. Ex Vivo Patient Sample Culture

[00472] Red blood cells were removed from remnant CLL MCL and ALL peripheral blood specimens using RBC Lysis Buffer (Thermo Fisher Scientific, Waltham, MA). The suspension of mononuclear cells was suspended in StemSpan SFEM II medium

(STEMCELL Technologies, Minneapolis, MN) supplemented with 10% HS-5 conditioned media. The conditioned Media was collected from HS-5 cells (ATCC, Manassas, VA) grown in 10% FBS (Thermo Fisher Scientific, Waltham, MA) in High Glucose DMEM (ATCC, Manassas, VA). HS-5 cells were maintained below passage 10 and in a 37°C, 95% humidity, 5% CO2 incubator. For analysis, some patient samples were plated in 384 well V-bottom plates (Greiner Bio-One, Kremsmiinster, Austria) at a density of 1 million cells/mL.

[00473] To generate a medium referred to herein as StemSpan SFEM IIC, the

StemSpan SFEM II medium supplemented as described above was further supplemented at varying concentrations with one or more cytokines: 0-200 ng/mL of IL6 (R&D Systems, Minneapolis, MN), 0-200 ng/mL of IL7 (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of G-CSF (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of GM-CSF (R&D Systems, Minneapolis, MN), 0-200 ng/mL of IL3 (R&D Systems, Minneapolis, MN), 0-200 ng/mL FLT3 Ligand (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of SCF

(Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of TPO (Miltenyi, Bergisch

Gladbach, Germany), 0-200 ng/mL of IL-2 (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of IL-4 (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of IL-21 (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of IL-10 (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of CD40L (Miltenyi, Bergisch Gladbach, Germany), 0-200 ng/mL of BAFF (Miltenyi, Bergisch Gladbach, Germany), and/or 0-200 ng/mL of IL-13 (Miltenyi, Bergisch Gladbach, Germany). 3. Drug Treatment and Priming

[00474] Bryostatin-1, Dexamethasone, Prednisolone, and Tretinoin (Sigma Aldrich, St. Louis, MO) were solubilized in DMSO and added at the concentrations indicated to cells in StemSpan SFEM IIC medium and plated into 384 well compound plates (Labcyte, San Jose, CA). Patient samples were compounded in triplicate with using a Labcyte Echo acoustic liquid handler. Compound plates were used only once and discarded after one freeze thaw. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours.

4. Flow Cytometry Screening

[00475] Cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma Aldrich, St. Louis, MO) and fluorescent-labelled primary antibodies: CD 19, CD20, CD5, CD45, CD22, CD3, and CD66B (Biolegend, San Diego, CA). Stains were directly dispensed into the patient samples plates using a Labcyte Echo acoustic liquid handler and then incubated at 4°C for 20 minutes. Samples were then assayed using an iQue Screener PLUS flow cytometer (Intellicyt, Albuquerque, NM) and data was analyzed in FlowJo (V10). The viable lymphocyte populations were gated by side scatter vs CD45 and B-cells were further gated from this population by CD 19 expression. T-cells were also gated from the lymphocyte population using CD3 as well as CD5 and were then used as an internal negative control for CD19, CD20, and CD22 expression, respectively. For CLL and MCL patient samples, abnormal B-cells were distinguished from healthy B-cells by the presence of CD5 expression. For ALL patient samples, abnormal B-cells are identified as CD19⁺, CD45 dim (or negative).

5. Assessment of CD19 Expression

[00476] CD 19 expression status as determined by flow cytometric screening was compared against independent clinical assessment of CD19 status for the CLL patient samples. CD 19 negative or positive expression were defined using the geometric mean fluorescent intensity (gMFI) of CD 19 expression in abnormal B-cell population compared to the internal negative control T-cell population which are known to be CD3 positive and CD 19 negative. CD 19 positive populations were defined as having a gMFI .2 log greater than the negative control. 6. Assessment of CD20 Expression

[00477] CD20 expression status as determined by flow cytometric screening was compared against independent clinical assessment of CD20 status for CLL and MCL patient samples. CD20 negative, dim, and positive expression were defined using the geometric mean fluorescent intensity (gMFI) of CD20 expression in abnormal B-cell population compared to the internal negative control T-cell population, which are CD20 negative. CD20 positive populations were defined as having a gMFI 1 log greater than the negative control, whereas CD20 dim population had between .1 to 1 log greater than the negative control. CD20 negative B-cell populations had gMFI within .1 logs of the negative control.

6. Assessment of CD22 Expression

[00478] CD22 expression status as determined by flow cytometric screening was compared against independent clinical assessment of CD22 status for the CLL/ALL/MCL patient samples. CD22 negative or positive expression were defined using the geometric mean fluorescent intensity (gMFI) of CD22 expression in abnormal B-cell population compared to the internal negative control T-cell population which are known to be CD3 positive and CD22 negative. CD22 positive populations were defined as having a gMFI .2 log greater than the negative control. .

Example B. CD20 Priming Of Cells Obtained From CLL Patient

Previously Treated With Anti-CD20 Therapy (Rituximab^®)

[00479] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient sample was plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

Dexamethasone, and/or DMSO and the indicated concentrations. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

Louis, MO) and fluorescent-labelled primary antibodies: CD 19, CD20, CD5, CD45, CD22, CD3, and CD66B (Biolegend, San Diego, CA). Stains were directly dispensed into the patient samples plates using a Labcyte Echo acoustic liquid handler and then incubated at 4°C for 20 minutes. Samples were then assayed using an iQue Screener PLUS flow cytometer (Intellicyt, Albuquerque, NM) and data was analyzed in FlowJo (V10). The viable lymphocyte populations were gated by side scatter vs CD45 and B-cells were further gated from this population by CD19 expression. T-cells were also gated from the lymphocyte population using CD3 as well as CD5 and were then used as an internal negative control for CD20 expression. Abnormal B-cells were distinguished from healthy B-cells by the presence of CD5 expression.

[00480] A CD20 positive CLL patient sample (Sample ID No. 674CLL2; CD20 status: CD20⁺) was prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (1 nM), Dexamethasone (50 nM), and a combination of Bryostatin-1 (1 nM) and Dexamethasone (50 nM) to increase expression of CD20. This patient had previously received treatment involving anti-CD20 therapy, Rituximab^®, and had relapsed. It was hypothesized that CLL patients that had previously been treated with an anti-CD20 therapy may be less responsive to priming of CD20 with single agent Bryostatin-1 due to compensatory changes in cell intracellular signaling networks or clonal selection.

[00481] An exemplary and representative result of this study is shown in FIGs. 3A-B. FIG. 3A, schematically depicting a histogram plot of CD20 staining intensity indicates that as single agents, Bryostatin-1 and dexamethasone have moderate effects on increasing CD20 antigen expression. However, when combination of Bryostatin-1 and dexamethasone is administered, a substantially and synergistically increase of expression of CD20 antigen is achieved. Similarly, the representation as depicted in FIG. 3B indicates that while the single agents show moderate increases of the CD20 antigen (mid cells), the combination of the two agents results in a substantial and synergistic increase in the CD20 high fraction of cells.

Example C. CD20 Priininp Of Cells Obtained From CLL Patient

Treated With Anti-CD20 Therapy (Ofatumumab^®)

[00482] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient sample was plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

Dexamethasone, and/or DMSO at the indicated concentrations. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma- Aldrich, St. Louis, MO) and fluorescent-labelled primary antibodies: CD 19, CD20, CD5, CD45, CD22, CD3, and CD66B (Biolegend, San Diego, CA). Stains were directly dispensed into the patient samples plates using a Labcyte Echo acoustic liquid handler and then incubated at 4°C for 20 minutes. Sample was then assayed using an iQue Screener PLUS flow cytometer (Intellicyt, Albuquerque, NM) and data was analyzed in FlowJo (V10). The viable lymphocyte populations were gated by side scatter vs CD45 and B-cells were further gated from this population by CD19 expression. T-cells were also gated from the lymphocyte population using CD3 as well as CD5 and were then used as an internal negative control for CD20 expression. Abnormal B-cells were distinguished from healthy B-cells by the presence of CD5 expression.

[00483] A patient that previously been treated with Ofatumumab^®, an anti-CD20 therapy, relapsed and lost expression of CD20 on their abnormal B-cells. Cells from this CD20 negative CLL patient (Sample ID No. 764CLL1; CD20 status: CD20 ) was prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (5 nM), Dexamethasone (50 nM), and a combination of Bryostatin-1 (5 nM) and

Dexamethasone (50 nM) to increase expression of CD20.

[00484] An exemplary and representative result of this study is shown in FIGs. 4A-B. The addition of single agent Bryostatin-1 partially restored CD20 antigen expression to the abnormal B-cells and dexamethasone had an even more moderate effect. However, when administered in combination dexamethasone and Bryostatin-1 led to a substantial and synergistic increase of both the number of cells positive for CD20 (FIG. 4B) as well as in the intensity of CD20 on those primed cells (FIG. 4A). Without priming, this patient sample would have remained CD20 negative, however, upon administering a combination of Bryostatin-1 and dexamethasone the CD20 negative cells regained CD20 antigen expression and thus, become sensitive to anti-CD20 therapy.

Example D. CD20 Priminp Of CD20 Dim Cells Obtained From CLL

Patients

[00485] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

Dexamethasone, and/or DMSO at the indicated concentrations. Samples were then incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

[00486] Cells from CD20 dim CLL patients (Patient I, Sample ID No. 671CLL1,

CD20 status: CD20 dim; Patient II, Sample ID No. 725CLL1, CD20 status: CD20 20 dim) were prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (1 nM), Dexamethasone (200 nM), and a combination of Bryostatin-1 (1 nM) and Dexamethasone (200 nM) to increase expression of CD20.

[00487] Exemplary and representative results of this study are shown in FIGs. 5A-B (Sample ID No. 671CLL1) and FIGs. 5C-D (Sample ID No. 725CLL1). As can be seen, in FIGs. 5A-5B (Patient I) and FIGs. 5C-5D (Patient II), both patient samples show little response to Bryostatin-1 as a single agent or to dexamethasone as a single agent. However, upon administering a combination of dexamethasone and Bryostatin-1, the aberrant B-cell populations of both patients show a substantial and synergistic increase in CD20 expression. Results described herein strongly indicate that increasing expression of CD20 on cells of CD20 dim patients renders those cells sensitive to anti-CD20 therapies.

Example E. CD20 Priming Of CD20 Positive Cells Obtained From CLL

Patient

[00488] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient sample was plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1, Dexamethasone, and/or DMSO at the indicated concentrations. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

Louis, MO) and fluorescent-labelled primary antibodies: CD 19, CD20, CD5, CD45, CD22, CD3, and CD66B (Biolegend, San Diego, CA). Stains were directly dispensed into the patient samples plates using a Labcyte Echo acoustic liquid handler and then incubated at 4°C for 20 minutes. Samples were then assayed using an iQue Screener PLUS flow cytometer (Intelbcyt, Albuquerque, NM) and data was analyzed in FlowJo (V10). The viable lymphocyte populations were gated by side scater vs CD45 and B-cells were further gated from this population by CD19 expression. T-cells were also gated from the lymphocyte population using CD3 as well as CD5 and were then used as an internal negative control for CD20 expression. Abnormal B-cells were distinguished from healthy B-cells by the presence of CD5 expression.

[00489] Cells from a CD20 positive CLL patient (Sample ID No. 707CLL1, CD20 status: CD20⁺) were prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (1 nM), Dexamethasone (200 nM), and a combination of Bryostatin-1 (1 nM) and Dexamethasone (200 nM) to increase expression of CD20.

[00490] An exemplary and representative result of this study is shown in FIGs. 6A-B. As depicted in FIGs. 6A-6B, this patient sample shows a moderate increase in CD20 antigen expression in response to Bryostatin-1 alone or in response to dexamethasone alone.

However, this response is substantially and synergistically increased upon administering a combination of Bryostatin-1 and dexamethasone. Results described herein strongly suggest that increasing expression of CD20 on CD20⁺ cells of patients will further sensitize those cells to anti-CD20 therapies.

Example F. CD20 Priininp Of Cells Obtained From CLL Patients

[00491] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

Dexamethasone, and/or DMSO at the indicated concentrations. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

[00493] Exemplary and representative results of this study is shown in FIGs. 7A-B. An increase in the log of the CD20 antigen expression (gMFI) compared to the vehicle treated control greater than .1 was taken as the threshold for a positive priming response. The response rate when administering Bryostatin-1 as a single agent was 25%; however, in combination with Dexamethasone the response rate increased to 75%.

Example G. CD 19 Priming Of Cells Obtained From CLL Patients [00494] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

Dexamethasone, and/or DMSO at the concentrations indicated. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours.

Abnormal B-cells were distinguished from healthy B-cells by the presence of CD5 expression.

[00495] Twenty-one (21) patient samples (Sample ID No. 670CLL1, CD19 status: positive; Sample ID No. 671CLL1, CD19 status: positive; Sample ID No. 674CLL1, CD19 status: positive; Sample ID No. 687CLL1, CD19 status: positive; Sample ID No. 690CLL1, CD19 status: positive; Sample ID No. 6934CLL1, CD19 status: positive; Sample ID No. 694CLL1, CD19 status: positive; Sample ID No. 707CLL1, CD19 status: positive; Sample ID No. 709CLL1, CD19 status: positive; Sample ID No. 710CLL1, CD19 status: positive; Sample ID No. 721CLL1, CD19 status: positive; Sample ID No. 725CLL1, CD19 status: positive; Sample ID No. 727CLL1, CD19 status: positive; Sample ID No. 726CLL1, CD19 status: positive; Sample ID No. 735CLL1, CD19 status: positive; Sample ID No. 736CLL1, CD19 status: positive; Sample ID No. 748CLL1, CD19 status: positive; Sample ID No. 749CLL1, CD19 status: positive; Sample ID No. 674CLL2, CD19 status: positive; Sample ID No. 755CLL1, CD19 status: positive; and Sample ID No. 746CLL1, CD19 status:

positive) were treated with Bryostatin-1 (1 nM), Dexamethasone (200 nM), and a combination of both agents as described in the methods. [00496] Exemplary and representative results of this study is shown in FIGs. 8A-B. An increase in the log of the CD 19 antigen expression (gMFI) compared to the vehicle treated control greater than .1 was taken as the threshold for a positive priming response. The response rate when administering Bryostatin-1 as a single agent was 66%; however, in combination with Dexamethasone the response rate increased to 72%. Results described strongly suggest that increasing expression of CD19 antigen on cancerous cells of patients will further sensitize those cells to anti-CD 19 therapies.

Example H. CD 19 Priming Of Cells Obtained From CLL Patient

[00497] Red blood cells were removed from the remnant CLL peripheral blood specimen using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1, Dexamethasone, and/or DMSO at the concentration indicated. Samples were then incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours.

Abnormal B-cells were distinguished from healthy B-cells by the presence of CD5 expression

[00498] Cells from a CD 19 positive CLL patient (CD 19 status: positive) were prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (1 nM), Dexamethasone (200 nM), and a combination of Bryostatin-1 (1 nM) and Dexamethasone (200 nM) to increase expression of CD 19.

[00499] An exemplary and representative result of this study is shown in FIGs. 9A-B. As depicted in FIGs. 9A-6B, this patient sample shows no increase of CD 19 antigen expression with dexamethasone alone and an increase in CD 19 antigen expression in response to Bryostatin-1 alone. However, this response is further increased upon

administering a combination of Bryostatin-1 and dexamethasone. Increasing expression of CD19 antigen on cells of patients with lymphoid malignancies (see, FIG. 1) might be expected to further sensitize responsive patient to anti-CD 19 therapies. Results described strongly suggest that increasing expression of CD19 antigen on cancerous cells of patients will further sensitize those cells to anti-CD 19 therapies.

Example I. CD 19 Priming Of Cells Obtained From B-ALL Patient

[00500] Red blood cells were removed from remnant a B-ALL peripheral blood specimen using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1, Dexamethasone, and/or DMSO at the concentration indicated. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

Stains were directly dispensed into the patient samples plates using a Labcyte Echo acoustic liquid handler and then incubated at 4°C for 20 minutes. Samples were then assayed using an iQue Screener PLUS flow cytometer (Intellicyt, Albuquerque, NM) and data was analyzed in FlowJo (V10). The viable lymphocyte populations were gated by side scatter vs CD45 and B-cells were further gated from this population by CD19 expression. T-cells were also gated from the lymphocyte population using CD3 as well as CD5 and were then used as an internal negative control for CD 19 expression. Abnormal B-cells are identified as CD19+, CD45 dim (or negative).

[00501] Cells from an ALL patient (Sample ID No. 825ALL1, CD19 status: positive) were prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (1 nM), Dexamethasone (200 nM), and a combination of Bryostatin-1 (1 nM) and Dexamethasone (200 nM) to increase expression of CD 19.

[00502] An exemplary and representative result of this study is shown in FIGs. 10A-B. As depicted in FIGs. 10A-6B, this patient sample shows no only a moderate increase of CD 19 antigen expression upon administering dexamethasone alone and a higher increase in CD 19 antigen expression in response to Bryostatin-1 alone. However, this response is further increased upon administering a combination of Bryostatin-1 and dexamethasone. Increasing expression of CD 19 antigen on cells of patients with earlier B-cell malignancies (see, FIG. 1) might be expected to further sensitize responsive patient to anti-CD 19 therapies. Results described herein strongly suggest that increasing expression of CD 19 antigen on cancerous cells of ALL patients will further sensitize those cells to anti-CD 19 therapies.

Example J. CD20 Priming With ND1000 Dosing Of CD20 Positive Cells

Obtained From CLL Patient

[00503] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

[00504] Cells from a CD20 positive CLL patient (Sample ID No. 674CLL2; CD20 status: CD20⁺) were prepared, primed and analyzed by flow cytometry as described in the methods above with various combinations of Bryostatin-1 (1 nM, 2.5 nM, or 5 nM) and Dexamethasone (50 nM, 100 nM, or 200 nM) to increase expression of CD20.

[00505] Exemplary and representative results of this study is shown in FIGs. 11 A-B. While in this patient sample, increasing concentrations of Bryostatin-1 showed further increased priming of CD20, this trend reversed with the use of low dose Dexamethasone (FIG. 11B). As demonstrated by this study, lower doses of Bryostatin-1 in combination with dexamethasone were more effectively to prime CD20 expression.

Example K. Unresponsive CD20 Priming With ND1000 Of CD20 Dim

Cells Obtained From CLL Patient

[00506] Red blood cells were removed from a remnant CLL peripheral blood specimen using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

Dexamethasone, and/or DMSO at the concentration indicated. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

[00507] Cells from a CD20 dim CLL patient (Sample ID No.735CLLl, CD20 status: CD20 dim) were prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (1 nM,), with Dexamethasone (200 nM) or with a combination of Bryostatin-1 and Dexamethasone to increase expression of CD20. In this rare patient sample, neither combination nor single agents increased CD20 expression. Thus, this rare patient sample provides a unique opportunity to identify underlying mechanism of non responsiveness to the compounds of the present invention.

Example L. CD22 Priming With ND1000 Of Cells Obtained From MCL

And CLL Patients [00508] Red blood cells were removed from remnant CLL and MCL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin- 1, Dexamethasone, and/or DMSO at the concentrations indicated. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

Louis, MO) and fluorescent-labelled primary antibodies: CD 19, CD20, CD5, CD45, CD22, CD3, and CD66B (Biolegend, San Diego, CA). Stains were directly dispensed into the patient samples plates using a Labcyte Echo acoustic liquid handler and then incubated at 4°C for 20 minutes. Samples were then assayed using an iQue Screener PLUS flow cytometer (Intellicyt, Albuquerque, NM) and data was analyzed in FlowJo (V10). The viable lymphocyte populations were gated by side scatter vs CD45 and B-cells were further gated from this population by CD19 expression. T-cells were also gated from the lymphocyte population using CD3 as well as CD5 and were then used as an internal negative control for CD22 expression. Abnormal B-cells were distinguished from healthy B-cells by the presence of CD5 expression.

[00509] Cells from a three CD22 patient samples (Sample ID No. 414CLL1, CD22 status: negative; Sample ID No. 423CLL1; CD22 status: negative; and Sample ID No.

381MCL1; CD22 status: positive) were prepared, primed and analyzed by flow cytometry as described in the methods above with Bryostatin-1 (5 nM,), with Dexamethasone (200 nM) or with a combination of Bryostatin-1 (5 nM) and Dexamethasone (200 nM) to increase expression of CD22.

[00510] Exemplary and representative results of this study is shown in FIG. 13. While in the patient samples analyzed, dexamethasone showed at best a very moderate increase of CD22 antigen expression and Bryostatin-1 a moderate increase, Bryostatin-1 in combination with dexamethasone showed a substantial and synergistic expression of CD22. Increasing expression of CD22 antigen on cells of patients with lymphoid malignancies (see, FIG. 1) might be expected to further sensitize responsive patient to anti-CD22 therapies. Results described herein strongly suggest that increasing expression of CD22 antigen on cancerous cells of patients will further sensitize those cells to anti-CD22 therapies. Example M. CD22 Priming With Bryostatin-1, Tretinoin,

Dexamethasone And Combinations Thereof Of Cells Obtained From CLL Patients

[00511] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

Dexamethasone, and/or DMSO at the concentrations indicated. Samples were then incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

[00512] Cells from a two CD22 patient samples (Sample ID No. 414CLL1, CD22 status: negative; Sample ID No. 423CLL1; CD22 status: negative) were prepared, primed and analyzed by flow cytometry as described in the methods above with dimethyl sulfoxide (control), with Bryostatin-1 (5 nM,), with Dexamethasone (200 nM), with Tretinoin (50 nM) or with combinations comprising Bryostatin-1 (5 nM) and Dexamethasone (200 nM) or Bryostatin-1 (5 nM) and Tretinoin (50 nM) to increase expression of CD22.

[00513] Exemplary and representative results of this study are shown in FIGs. 14A and 14B. While in patient sample 414CLL1, dexamethasone showed a very moderate increase of CD22 antigen expression, somewhat higher expression levels were observed upon administering tretinoin or Bryostatin-1 alone. However, both combinations, i.e., Bryostatin-1 in combination with dexamethasone and Bryostatin-1 in combination with tretinoin showed a substantial and synergistic expression of CD22 (FIG. 14A). A similar observation was made in patient sample 423CLL1 (FIG. 14B). Increasing expression of CD22 antigen on cells of patients with lymphoid malignancies (see, FIG. 1) might be expected to further sensitize responsive patient to anti-CD22 therapies. Results described herein strongly suggest that increasing expression of CD22 antigen on cancerous cells of patients will further sensitize those cells to anti-CD22 therapies.

Dexamethasone And Combinations Thereof Of Cells Obtained From ALL Patient

[00514] Red blood cells were removed from remnant a B-ALL peripheral blood specimen using RBC Lysis Buffer and cultured as described previously. Patient samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1, Dexamethasone, and/or DMSO at the concentrations indicated. Samples were incubated in a robotic 37°C, 95% humidity, 5% CO2 incubator for 96 hours. Following incubation, cell numbers, viability, and drug-induced changes in expression of antigen cell surface markers were determined by flow cytometry. Cells were stained with DAPI (Sigma-Aldrich, St.

Louis, MO) and fluorescent-labelled primary antibodies: CD 19, CD20, CD5, CD45, CD22, CD3, and CD66B (Biolegend, San Diego, CA). Stains were directly dispensed into the patient samples plates using a Labcyte Echo acoustic liquid handler and then incubated at 4°C for 20 minutes. Samples were then assayed using an iQue Screener PLUS flow cytometer (Intellicyt, Albuquerque, NM) and data was analyzed in FlowJo (V10). The viable lymphocyte populations were gated by side scatter vs CD45 and B-cells were further gated from this population by CD19 expression. T-cells were also gated from the lymphocyte population using CD3 as well as CD5 and were then used as an internal negative control for CD22 expression. Abnormal B-cells are identified as CD19+, CD45 dim (or negative).

[00515] Cells from an ALL patient (Sample ID No. 825ALL1, CD22 status: positive) were prepared, primed and analyzed by flow cytometry as described in the methods above with dimethyl sulfoxide (control), with Bryostatin-1 (5 nM,), with Dexamethasone (200 nM), with Tretinoin (50 nM) or with combinations comprising Bryostatin-1 (5 nM) and

Dexamethasone (200 nM) or Bryostatin-1 (5 nM) and Tretinoin (50 nM) to increase expression of CD22. [00516] An exemplary and representative result of this study is shown in FIG. 15. While in this patient sample the combinations of Bryostatin-1 and dexamethasone did not result in an increase of CD22 antigen expression, but rather in a reduced expression when compared to Bryostatin-1 alone, a composition comprising Bryostatin-1 and tretinoin showed a higher expression of CD22 than what was obtained with either compound alone (FIG. 15). While the response to Bryostatin-1 and dexamethasone in patient sample 825ALL1 is under investigation, results presented herein unequivocally demonstrate that Bryostatin-1 in combination with dexamethasone substantially and synergistically increase expression of CD22 antigen across multiple mature lymphoid malignancies. In that regard, it is noteworthy that across multiple CLL patient samples tested a combination comprising Bryostatin-1 and Tretinoin shows greater CD22 priming than a combination of Bryostatin-1 and

dexamethasone (e.g., FIGs. 14A, B). In an ALL patient sample, this phenomenon was even more apparent. Here, the combination of Bryostatin-1 and Dexamethasone actually suppressed the single agent priming of CD22 by Bryostatin-1 (FIG. 15). In contrast, the combination of Bryostatin-1 and Tretinoin significantly increased priming of CD22 antigen when compared to either Bryostatin-1 alone or Tretinoin alone (FIG. 15). Increasing expression of CD22 antigen on cells of patients with earlier B-cell malignancies (see, FIG. 1) might be expected to further sensitize responsive patient to anti-CD22 therapies. Results described herein strongly suggest that increasing expression of CD22 antigen on cancerous cells of patients will further sensitize those cells to anti-CD22 therapies.

Example O. CD20 Priming With Bryostatin-1 And Glucocorticoid

Combinations Of Cells Obtained From CLL Patient

[00517] Red blood cells were removed from remnant CLL peripheral blood specimens using RBC Lysis Buffer and cultured as described previously. Patients samples were plated in 384 well V-bottom at a density of 1 million cells/mL, treated with Bryostatin-1,

[00518] Cells from a CLL patient (Sample ID No. 803CLL1; CD20 status: CD20 dim) were prepared, primed and analyzed by flow cytometry as described in the methods above with with Bryostatin-1 (5 nM,), with Dexamethasone (200 nM), with Prednisolone (220 nM) or with combinations comprising Bryostatin-1 (5 nM) and Dexamethasone (200 nM) or Bryostatin-1 (5 nM) and Prednisolone (50) to increase expression of CD20.

[00519] An exemplary and representative result of this study is shown in FIG. 16. While in this patient sample neither dexamethasone nor prednisolone resulted in an increase of CD20 antigen expression, but rather in a decrease of CD20 antigen expression, compositions comprising Bryostatin-1 and dexamethasone or Bryostatin-1 and prednisolone showed a significantly higher expression of CD20 than what was obtained with Bryostatin-1 alone (FIG. 16). As demonstrated herein, Bryostatin-1 shows increased priming of CD20 not only in combination with Dexamethasone but also with other glucocorticoids, such as prednisolone. This finding suggests that the combination effect is at least in part mediated by a glucocorticoid receptor signaling pathway. Increasing expression of CD20 antigen on cells of patients with lymphoid malignancies (see, FIG. 1) might be expected to further sensitize responsive patient to anti-CD20 therapies. Results described herein strongly suggest that increasing expression of CD20 antigen on cancerous cells of patients will further sensitize those cells to anti-CD20 therapies.
