Definitions
- Chronic obstructive pulmonary disease is characterized by a chronic inflammatory process and irreversible airflow obstruction with a decline in the lung function FEV1 (i.e., forced expiratory volume in 1 second).
- the disease may be divided into two subgroups, namely chronic bronchitis and emphysema.
- Chronic bronchitis is characterized by mucus hypersecretion from the conducting airways, inflammation and eventual scarring of the bronchi (airway tubes).
- Emphysema is characterized by destructive changes and enlargement of the alveoli (air sacs) within the lungs.
- Many persons with COPD have a component of both of these conditions. COPD patients have difficulty breathing because they develop smaller, inflamed air passageways and have partially destroyed alveoli.
- the presenting symptoms for COPD are typically breathlessness
- Chronic bronchitis can also be diagnosed by asking the patient whether they have a "productive cough," i.e. one that yields sputum.
- COPD patients are traditionally treated with bronchodilators and/or anticholinergics and evaluated by spirometry for the presence of airflow obstruction and reversibility. If airflow obstruction is present and reversibility less than 15%, particularly in a smoker, then they are often diagnosed as having COPD.
- COPD is characterized by an increase in the activation and/or number of alveolar macrophages, CD 8 + T-cells and neutrophils.
- the neutrophil is believed to play a central role in the pathophysiology of COPD.
- Neutrophil activation results in the release of a number of inflammatory mediators and proteinases, most importantly neutrophil elastase which contributes to the progressive fibrosis, airway stenosis and destruction of the lung parenchyma, leading to an accelerated decline in airway function.
- Neutrophil elastase also induces mucus secretion and thus may contribute to the characteristic mucus hypersecretion that characterizes COPD.
- Transdermal patches of embodiments of the invention have an adhesive matrix which includes both a beta agonist, e.g., tulobuterol, and an anticholinergic, e.g., scopolamine, where the matrix is configured to be storage-stable and provide for extended release of the beta agonist and anticholinergic.

Pursuant to 35 U.S.C. § 1 19 (e), this application claims priority to the filing date of the United States Provisional Patent Application Serial No. 61 /436,489, filed January 26, 201 1 ; the disclosure of which is herein incorporated by reference. INTRODUCTION
Chronic obstructive pulmonary disease (COPD) is characterized by a chronic inflammatory process and irreversible airflow obstruction with a decline in the lung function FEV1 (i.e., forced expiratory volume in 1 second). The disease may be divided into two subgroups, namely chronic bronchitis and emphysema. Chronic bronchitis is characterized by mucus hypersecretion from the conducting airways, inflammation and eventual scarring of the bronchi (airway tubes). Emphysema is characterized by destructive changes and enlargement of the alveoli (air sacs) within the lungs. Many persons with COPD have a component of both of these conditions. COPD patients have difficulty breathing because they develop smaller, inflamed air passageways and have partially destroyed alveoli.
The presenting symptoms for COPD are typically breathlessness
accompanied by a decline in FEV1 . Chronic bronchitis can also be diagnosed by asking the patient whether they have a "productive cough," i.e. one that yields sputum. COPD patients are traditionally treated with bronchodilators and/or anticholinergics and evaluated by spirometry for the presence of airflow obstruction and reversibility. If airflow obstruction is present and reversibility less than 15%, particularly in a smoker, then they are often diagnosed as having COPD.
At the cellular level, COPD is characterized by an increase in the activation and/or number of alveolar macrophages, CD8 + T-cells and neutrophils. The neutrophil is believed to play a central role in the pathophysiology of COPD.
Neutrophil activation results in the release of a number of inflammatory mediators and proteinases, most importantly neutrophil elastase which contributes to the progressive fibrosis, airway stenosis and destruction of the lung parenchyma,
leading to an accelerated decline in airway function. Neutrophil elastase also induces mucus secretion and thus may contribute to the characteristic mucus hypersecretion that characterizes COPD.
Currently, there is no known cure for COPD.

components. Additional components of interest include, but are not limited to, a transdermal absorption enhancer, a preservative (e.g., paraben), a stabilizing agent, a filling agent that contains a hydrophilic polymer; cross-linking agents; etc.
However, in some embodiments, the transdermal patch does not include any of these additional components.
ADDITIONAL CHARACTERISTICS
As summarized above, an aspect of the subject transdermal patches is that they are storage stable. By storage-stable is meant that the compositions may be stored for extended periods of time without significant degradation and/or significant reduction in activity of the beta agonist and anticholinergic active agents. In certain embodiments, the subject compositions are stable for 3 years or longer, etc., when maintained at 25°C. In some instances, the above storage stability values are determining using the protocol described in United States Published Application Publication No. US 2009-0297590, modified to evaluate the presence of the beta agonist and anticholinergic free base (the disclosure of the storage stability assay reported in this publication is specifically incorporated by reference).
In some embodiments, the adhesive layers are self-adhesive, i.e., inherently adhesive, and thus may be fixed in a position over the skin, i.e., removably bonded to and/or about a given skin surface, without the use of additional adhesives or other means to hold the transdermal patch in place over the formulation. As the adhesive compositions are adhesive, when applied to human skin they remain stably positioned at the site of application. As such, application of force is required to remove the adhesive compositions from the site of application. While application of force is required for removal, the adhesive compositions are not so adhesive such that removal of the compositions irritates or wounds the skin site to which the compositions were applied. In certain other embodiments, a subject transdermal patch may be held in a fixed position on a skin surface using a separate adhesive such as an adhesive backing or the like or a combination of inherent adhesiveness and an additional separate adhesion means may be employed.
The shape of the patch may vary, where shapes of interest include, but are not limited to: square, rectangle, oval, circle, etc. The size of the patch may also vary, where in certain embodiments the size ranges from about 1 to 20 cm2, such as 1 to 1 5 cm2, such as 1 to 10 cm2.
BACKING LAYER
The transdermal patch, which includes an adhesive layer, e.g., as described above, also includes a backing (i.e., support), where the adhesive layer is present on a surface of the backing. The backing may be made of a flexible material which
is capable of fitting in the movement of human body. Flexible materials of interest include, but are not limited to: various non-woven fabrics, woven fabrics, spandex, flannel, or laminates of these materials with polyethylene film, polyethylene glycol terephthalate film, polyvinyl chloride film, ethylene-vinyl acetate copolymer film, polyurethane film, and the like.
Suitable backing layer materials include, but are not limited to, polyethylene terephthalate, polyethylene, polypropylene, vinyl acetate-vinyl chloride copolymer, polyurethane, acetylcellulose, ethylcellulose, soft polyvinyl chloride, polyvinylidene chloride, polytetrafluoroethylene, polyamide, paper, a single film of metal foil such as aluminum foil or a laminated film of foil, woven or unwoven fabric made from the aforementioned materials, and combined materials with the aforementioned films.
RELEASE FILM
In addition to the adhesive layer and the backing, transdermal patches may also include a release film (shown as element 16 in FIG. 1 ) on the surface of the adhesive layer that is opposite the backing. The release film may provide for protection of the adhesive layer from the environment. The release film may be any convenient material, where release films include polyesters, such as PET
(polyethylene terepthalate) or PP (polypropylene), and the like.
SEALED PACKAGE
In certain embodiments, transdermal patches are present in a sealed package. The sealed package may be fabricated from a packaging material that includes a hydrophilic layer to prevent the passage of oxygen, and a hydrophobic layer to prevent passage of moisture and other polar materials. Barrier materials of interest also include metallic layers, e.g., aluminum, where in certain embodiments, the barrier layer is an aluminum layer. This barrier layer has a thickness sufficient to provide for the barrier function, where the thickness may range in some instances from 5 to 15, such as 6 to 10 μιη. In certain embodiments, the package is a laminate of the barrier layer in combination with one or more additional layers, e.g., polymeric layers, paper layers, etc. An aluminum containing package that may be used with the subject patch preparations is sold by Dainippon Printing Co., Ltd. (Kyoto, Japan).
EXTENDED- RELEASE TRANSDERMAL PATCH FABRICATION
Transdermal patches of the invention may be fabricated using any
convenient protocol. In one protocol of interest, components of the adhesive layer, e.g., matrix components such as the rubber, adhesive resin, higher fatty acid, plasticizer and anti-oxidant are combined with the active agents using any convenient combination protocol to produce a solution; and then the solution is pasted onto backing and dried. When the adhesive base is pasted in a hot melt method, the adhesive polymer components may be first dissolved; then other components (e.g., active agents etc.,) may be added and pasted onto the backing. The opposing surface of the adhesive layer may then be conveniently covered with a release liner.
One convenient protocol for fabrication of a transdermal patch includes preparing an adhesive paste through the uniform mixing of the aforementioned ingredients and then coating the paste onto the support, followed by cutting of the resultant product to the specified size to obtain the desired transdermal patch preparation. The resultant transdermal patch preparation is then heat-sealed, one sheet to a package, using a suitable packaging material, to obtain the sealed transdermal patch.
It should be noted that the above manufacturing protocols are merely examples of fabrication protocols of interest. Any convenient protocol that is capable of producing transdermal patch, as described above, may be employed.
METHODS
The present invention provides methods of delivering a beta agonist and an anticholinergic to an individual in need thereof. Aspects of the methods include contacting a topical surface of an individual with a transdermal patch, e.g., as described above. The topical surface is generally a skin surface, such that embodiments of the invention include contacting a skin surface of an individual with a transdermal patch in a manner sufficient to deliver a therapeutic amount of the beta agonist and anticholinergic to the individual for an extended period of time.
In practicing the invention, the transdermal patch is applied to any convenient skin surface. Skin surfaces of interest include, but are not limited to: arms, leg, torso (e.g., stomach or back), head, neck, etc. The surface area that is covered by the transdermal patch following application is generally sufficient to provide for the
desired amount of active agent administration, and in certain embodiments ranges froml cm2 to 20 cm2, such as from 1 cm2 to 10 cm2.
Following application of a topical patch, as described above, the applied patch is maintained at the target site for a period of time sufficient for delivery the desired amount of active agents. In some instances, the period of time is 6 hours or longer, such as 12 hours or longer, including 24 hours or longer.
Practice of methods according to certain embodiments results in extended release of the active agents from the transdermal patch. In some instances, practice of the methods results in a plasma level of a beta agonist, e.g., tulobuterol, which ranges from 0.5 ng/ml to 5 ng/ml, such as 1 ng/ml to 3 ng/ml. In some instances, practice of the methods provides a plasma level of an anticholinergic, e.g., scopolamine, which ranges from 0.1 ng/ml to 1 .0 ng/ml, such as 0.2 ng/ml to 0.4 ng/ml. While the extended period of time over which the therapeutic amount is provided may vary, in some instances the extended period of time is 6 hours or longer, such as 12 hours or longer, including 24 hours or longer.
In some embodiments, a transdermal patch, when applied to a skin surface of an individual, will provide a relatively constant plasma level of the active agents over the extended period of time. A "relatively constant" level is a level that varies by no more than about 60%, e.g., less than about 40%, less than about 30%, or less than about 20%, over a given period of time.
In practicing the subject methods, a transdermal patch is generally applied a single time over a given time period. The dosing schedule may be daily, such that an old patch is replaced with a new patch every 24 hours. In some cases, the patch may be designed for multi-day use, such as three days.
UTILITY
Transdermal patches of the invention find use in the treatment of any condition in which it is desired to deliver a beta agonist and an anticholinergic agent to a subject. Of interest are pulmonary conditions such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, etc. Treating an individual diagnosed with COPD encompasses a method of inhibiting the progression of COPD in an individual diagnosed with COPD. By "inhibiting the progression of COPD" is intended to mean that the progressive histological and morphometric changes
associated with the clinical sequelae of COPD, including inflammation, alveolar remodeling, and lung cell death, are attenuated.
KITS
Also provided are kits, where the subject kits at least include one or more transdermal patches (e.g., as described above), as well as instructional material for using the same, e.g., in the methods of the invention. In certain embodiments, the kits include two or more transdermal patches as described above. A transdermal delivery patch in a kit may be present in a package, as described supra. The transdermal patches of the kits may be present in individual pouches or analogous containers, to preserve the composition of the patches until use.
The subject kits also may include instructions for how to use the patches, where the instructions typically include information about where to apply the patch, dosing schedules etc. The instructions may be recorded on a suitable recording medium. For example, the instructions may be printed on a substrate, such as paper or plastic, etc. As such, the instructions may be present in the kits as a package insert, in the labeling of the container of the kit or components thereof (i.e.
associated with the packaging or subpackaging) etc. In other embodiments, the instructions are present as an electronic storage data file present on a suitable computer readable storage medium, e.g. CD-ROM, diskette, etc.
