Definitions
- the present invention relates to the field of vaccine development, specifically, to the development of immunopotentiators and the vaccine formulations resulting from their use.
- the technical objective of the proposed invention is to promote an increase in the immune response against antigens administered in nasal formulations and to develop new formulations for vaccine use by this route.
- This invention is also related to obtaining multivalent vaccine formulations for nasal administration, which have as their central antigen the Hepatitis B virus surface antigen, capable of enhancing the immunogenicity of the antigens contained therein after nasal co-administration of the antigens of interest described in the formulations object of the invention.
- the formulations of the present invention are multivalent formulations that contain the Hepatitis B Virus surface antigen and other antigens, including soluble antigens such as toxoids, their conjugates, as well as inactivated or attenuated vaccine microorganisms.
- Other antigens routinely used in commercial immunization have been used in these formulations with identical results and with immunogenicity levels similarly similar to those obtained after parenteral administration in conventional formulations, both from the humoral and cellular point of view, and with the additional advantage of inducing a strong mucosal response from mucosal immunization, which is a unique feature of this type of formulations.
- Another important aspect is the economy of components of these formulations, which allow avoiding the use of nasal adjuvants, turning the formulation's own antigens into elements capable of favoring the increased response to the other co-administered antigens.
- the mucosal surface of the gastrointestinal, respiratory, and genitourinary tracts occupies a surface area of at least 400 m 2 (McKenzie SJ, Halsey J A. 1984; J. Immunol., 53: 1818). Furthermore, a highly specialized immune system protects the mucosal surfaces. In a healthy adult, this local immune system contains at least 80% of all lymphocytes, which can be found there, or transiting between various lymphoid tissues associated with mucosa (Report of the Expert Panel VI: Concerted efforts in the field of mucosal immunology. 1996. Vaccine; 14: 644).
- the mucosal immune system divides into local inducer sites, called mucosal-associated organized lymphoid tissues (O-MALT), and into effector sites (Kraehenbuhl JP and Neutra M N. 1992. Physiol. Rev.; 72: 853).
- O-MALT mucosal-associated organized lymphoid tissues
- Most of the O-MALT studies have been conducted on lymphoid tissues associated with the gastrointestinal tract (GALT), including Peyer's patches (PP), the appendix, and isolated lymph nodes that abound in the rectum.
- GALT gastrointestinal tract
- PP Peyer's patches
- NALT nasal lymphoid tissue
- the epithelium ranges from pseudostratified to simple. In the bronchi, the area of the simple epithelium, the intercellular spaces are sealed by tight junctions and the main mechanism for taking antigens is through M cells. At the level of the tonsils, the predominant epithelium is stratified, where the absorption mechanism of the antigen is closely associated with a network of macrophages and mobile dendritic cells from the bone marrow, up to 700 cells per mm 2 . These cells are capable of migrating to O-ALTs and lymph nodes presenting the processed antigen that was phagocytized on the surface of the tonsils.
- Mucosal inoculation of vaccine antigens offers multiple advantages over vaccines administered parenterally; among them: increasing safety and minimizing adverse effects (Editorial. Typhoid vaccination: Weighing the options. 1992. Lancet: 340-341; Redhead K and Griffiths E. 1990. Curr. Opin. Infect. Dis. 3 : 380), the reduction of qualified personnel and the logistics of vaccination, and the increase in the effectiveness of vaccination in the elderly and newborns.
- the human systemic immune system has been shown to depress with age, while studies in mice have shown non-depression of mucosal immune functions with advancing age (Bergman KC and Waldman R H. Rev. 1988. Infect. Dis.
- Mucosal immunization in addition, can facilitate the eradication of some diseases caused by pathogens that remain colonizing, asymptomatically the mucosal surfaces (Kraehenbuhl J P and Neutra M N. 1992. Physiol Rev.72: 853). This is because this type of immunization can not only generate systemic, but also mucosal responses, which is not achieved through inoculations by the parenteral route.
- the required amount of antigen for mucosal immunizations may be greater than that required for parenteral immunizations, probably due to various factors such as: the relative inefficiency of the entry of the intact antigen to the mucosal lymphoid tissue, the acidic and proteolytic barriers, intestinal peristalsis, among others. From this derives the necessary development of adjuvants or adjuvant strategies for mucosal use (Faden H, et al. 1990. J. Infect. Dis. 162: 1291; Shahin RD, et al. 1990. Infect. Immun. 58: 4063 ; O ⁇ agan D T. 1990. Curr Opin Infect Dis. 3: 393).
- Adjuvants are substances or procedures that accelerate, prolong, or enhance the specific immune response against antigens inoculated by mucosal or parenteral routes (Vogel FR. Adjuvants in perspective. In: Brown F, Haaheim LR, editors. Modulation of the immune response to vaccine antigens. Dev. Biol. Stand. Basel. Karger; 1998; 92: 241-248).
- Mucosal adjuvants are those that enhance the immune response against antigens administered mucosally.
- mucosal adjuvants include V. cholerae enterotoxin (CT), and E. coli heat-labile toxin (LT).
- CT V. cholerae enterotoxin
- LT E. coli heat-labile toxin
- the adjuvant activity of CT is related to the ribosylation of ADP (adenosine diphosphate) and the induction of cAMP (cyclic adenosine monophosphate) that has various cellular effects (Lycke N, et al. 1991. Scand. J. Immunol. 33 : 691).
- CT subunit B has the ability to increase epithelial permeability to heterologous antigens administered by the nasal route, not so for those administered orally (Lycke N, et al. 1991. Scand. J. Immunol. 33: 691 ; Gizurarson S, et al. 1991. Vaccine 9: 825; Gizurarson S, et al. 1992. Vaccine. 10: 101). Furthermore, CT has been shown to induce long-lasting immunological memory in the intestinal lamina intestinal of mice (Vajdy M and Lycke NH. 1992. Immunology. 75: 488). To date, it has been impossible to selectively separate the adjuvant and toxic effects of CT (Lycke N. et al. 1992.
- Some adjuvants used parenterally have also been evaluated mucosally; including: immunostimulatory complexes (ISCOMs), liposomes, lysophosphatidyl glycerol, Avridine (a lipoidal amine), and cytokines (Ruby J, et al. 1992. Vaccine. Res. 1: 347; O ⁇ agan DT, et al. . 1992. J Gen Virol; 73: 2141). Immunostimulatory complexes have been shown to be efficient adjuvants via the nasal route.
- ISCOMs immunostimulatory complexes
- liposomes lysophosphatidyl glycerol
- Avridine a lipoidal amine
- cytokines cytokines
- Liposomes are nothing more than aqueous suspensions of spheroidal vesicles, in which the phospholipids they contain are organized in lipid bilayers. Antigens can be transported within the vesicles as well as on their surface, according to their hydrophilic or hydrophobic character, respectively (Childers NK, Michalek S M. Liposomes, in: DT Hagan (Ed.), Novel Delivery Systems for Oral Vaccines, CRC Press, Inc., Boca Raton, Florida, 1994). Its adjuvanticity depends on the number of layers (Susuki M, et al. 1994. Clin Immunother. 2: 121-125), loading (Hadden JW. 1993.
- Microcapsules are nothing more than spheres consisting of a shell and a core.
- the shell may be made of one or more polymers, whether biodegradable or not, while the core is made of antigen. If the polymer is not biodegradable, the microcapsule acts as a reservoir through whose pores the antigen escapes slowly. If the polymer is biodegradable, the antigen is released as the microsphere degrades.
- microspheres encapsulated with the copolymer of lactic acid and glycolic acid.
- the microspheres have been used intranasally (Eyles JE, et al. 1999. Int J Pharm. 189 (1): 75-9), orally and parenterally (Gupta RK, et al. 1997. Vaccine; 15 (16): 1716- 1723).
- VLPs Virus-like particles
- HPV VLP human papilloma virus
- CpG ODN Intranasal immunization of BALB / c mice with HBsAg and as adjuvant oligodeoxynucleotides with CpG motifs (CpG ODN) has been shown. produces an immune response of antibodies against the viral antigen, of equal magnitude to that produced by CT or LT with HBsAg, and greater than the combination of CTB or LTK63 (mutated variant of LT) with HBsAg. Furthermore, the simultaneous use of the CpG ODN, CT (or LT) and HBsAg by the nasal route produces a synergistic effect on the immune response against the latter antigen, not manifesting itself when CTB or LTK63 are used instead of toxins (McCIuskie MJ, ef al.
- acemannan an acetylated mannose polymer, extracted from the Aloe barbadensis Miller plant
- HBsAg a serum IgG antibody response similar to that obtained with administration of the adjuvant antigen alumina, as well as an IgA response in vaginal secretions, comparable to that obtained with intranasal application of HBsAg adjuvant with cholera toxin (Aguilar JC et al. 1998. WO 9839032).
- HBcAg hepatitis B virus nucleocapsid antigen
- Diphtheria toxoid has an important space in the current vaccine literature, mainly by parenteral routes. There are some works that have used it by the nasal route. Primary parenteral immunization with diphtheria toxoid in alumina, followed by secondary intranasal immunization with CRM - I97 - constitutes a highly effective immunization method in mice, capable of inducing high levels of anti-DT IgG and neutralizing antibodies in serum and secretory IgA in the respiratory tract (McNeela EA, et al. 2000. Vaccine. Dec 8; 19 (9-10): 1188-98). When administered intranasally to mice, the recombinantly obtained E.
- rLTB heat-labile enterotoxin B subunit
- CTB recombinantly
- sufficiently high titers of diphtheria antitoxin greater than 0.1 IU / mL, were obtained in mice showing high levels of DT-specific serum IgG antibody responses.
- the tetanus toxoid also stands out for having an important space in the current vaccine literature, mainly in parenteral immunization strategies, like DT.
- IL-6, IL-12 interleukins 6 and 12
- TT tetanus toxoid
- IL-12 administered intranasally in conjunction with TT not only induced sharp increases in serum IgG, but also elevated IgA antibody responses in mucosa.
- Co-administration of IL-6, IL-12, and TT did not increase serum or mucosal antibody responses, relative to those produced by the combination of IL-12 with TT (Boyaka PN, et al. 1999. J Immunol. Jan 1 ; 162 (1): 122-8).
- Intranasal administration of IL-12 to mice previously nasally immunized with TT antigens and CT adjuvant resulted in an increase in levels of TT-specific IgG2a and IgG3 antibodies, while IgG1 and IgE antibody responses were markedly reduced .
- intranasally applied IL-12 increased CT-induced serum IgG1 and IgE antibody responses in mice given the mixture of TT and CT orally (Marinaro M. et al. 1999. J Immunol. Jan 1; 162 (1): 114-21).
- TT formulations the systemic and mucosal responses of mice immunized with TT adsorbed on alumina and mixed with rCTB were examined.
- 5 Lf were necessary to stimulate, only in the presence of rCTB (10 ⁇ g), high responses of TT-specific serum IgG antibodies in all the mice examined, and moderate or light IgA antibody responses.
- TT has also been used as a model in the testing of new adjuvants such as the non-toxic variant of CT: CTS61 F. Comparative studies of the immune responses generated by intranasal administration of this protein with several separate antigens have been performed. (among them the TT), and those obtained following a similar protocol with native CT and with rCTB.
- TT-specific serum IgG, IgA, and IgM responses, as well as IgA antibody response in mucosal secretions were significantly increased in both the native CT formulation and the mutated CT formulation; rCTB did not show good adjuvant activity (Yamamoto S. ef al. 1997. Proc Nati Acad Sci US A. May 13; 94 (10): 5267-72).
- Nasal administration to guinea pigs of the tetanus toxoid adsorbed on poly-L-lactic acid microspheres increased the immune response with respect to that obtained with the free antigen; the latter was similar to that of non-immunized animals (Almeida AJ, et al. 1993. J Pharm Pharmacol.
- Another of the antigens that are universally used in human vaccines is formaldehyde-inactivated Bordetella pertussis (Bp).
- Bp Bordetella pertussis
- This bacterin administered by the nasal route to BALB / c mice, induces high levels of IgG antibodies in serum and bronchioalveolar fluids, as well as IgA in serum, saliva, bronchioalveolar fluids, and stool extracts.
- IgG responses against Bp do not increase, while IgA responses are significantly reduced in all secretions analyzed (Berstad AK, ef al. 1997. Vaccine. Aug-Sep; 15 (12-13): 1473-8).
- mice In order to test the immunogenicity and nasal adjuvanticity of Bp, an investigation was carried out in mice in which this antigen was administered intranasally, together with the inactivated influenza virus.
- the virus administered alone it induced low levels of serum influenza-specific IgG antibodies, although these were significantly higher than those of the non-immunized controls, while there were no differences between the serum and saliva IgA responses.
- serum IgA and IgG responses and virus-specific salivary IgA were substantially increased (P ⁇ 0.005).
- this adjuvant effect was not significant for responses of the same type in the intestine (measured as antibodies in faeces).
- Bp has also been tested in humans. Six adults were given pertussis cell vaccines four times, via the nasal route, with a weekly interval. All of the vaccinates responded with increases in IgA antibodies in nasal fluids against the Bp whole cell antigen. Three of those vaccinated with high nasal antibody responses also developed increased serum IgA and IgG antibody titers against Bp. Antibody responses in saliva against whole cell antigen, as well as serum antibodies and secretions against pertussis toxin (PT) and hemagglutinin filamentous (FHA) were negligible, with the exception of a moderate increase in antibodies against FHA in the nasal fluid.
- PT pertussis toxin
- FHA hemagglutinin filamentous
- CPME administered in the form of nasal drops or nasal spray 4 times, with a weekly interval between each application, has been shown to lead to the development of IgA responses in nasal and salivary secretions in humans.
- modest increases in serum IgG have been observed in several of the immunized individuals (Haneberg B, ef al. 1998. Infec ⁇ Immun Apr; 66 (4): 1334-41).
- the additional use of CT by mucosal routes increases the responses of serum antibodies compared to the CPME vaccine administered by the same routes.
- the most effective immunizations have been nasal, from which it is derived that the mucosal responses are not dependent on the use of CT.
- the antibody response to the HBsAg, DT, TT and Bp animens is not affected when a vaccine containing Haemophilus influenzae type B (PRP) capsular polysaccharide (PRP-TT), HBsAg is parenterally administered to infants. , DT, TT and Bp anigenic or when two vaccines were administered by the same route, one with HBsAg, DT, TT and Bp anigenic, and heard with PRP-TT only.
- the antibody response against the first four antigens mentioned is not affected when a formulation obtained from the mixture of the HBsAg, DT, TT vaccine and Bp antigens is applied to reconstruct the lyophilized PRP-TT.
- the antibody response against the PRP is significantly lower in the latter case (Greenberg DP, ef al. 2000. Pedia ⁇ r Infec ⁇ Dis J. Dec; 19 (12): 1135-40).
- Vaccination with a formulation containing only HBsAg and PRP (the latter conjugated to the CPME of N. meningitidis) from healthy adults who have been previously exposed to these aniodors, increased the levels of antibodies. serum con ⁇ ira the an ⁇ genes (Bulkow LR, ef al. 1993. Arc ⁇ ic Med Res Jul; 52 (3): 118-26).
- the formulations of the present invention are multi-formulations that contain the surface anigenic of Hepali ⁇ is B virus and other anigens, including soluble antigens such as toxoids, their conjugates, as well as inactivated or attenuated vaccine microorganisms.
- Other antigens routinely used in commercial immunization have been used in this type of formulations where the potentiating effect of HBsAg was evidenced and with levels of immunogenicity equally similar to those obtained after parenteral administration in conventional formulations, since the humoral and cellular point of view, and with the additional advantage of inducing from mucosal immunization a strong response at the mucosa level, a unique characteristic of this type of formulations.
- Another aspect of importance is the economy of the components of these formulations, which allow the use of nasal adjuvants to be avoided, turning the anigens of the formulation into elements capable of promoting increased response to co-administered amphotogenic drugs.
- HBsAg used in the present invention is novel since there are no mulfivaleni formulations for nasal administration of the surface anigenic in which an enhancing effect is evidenced from the coadminiration of the surface antigen and the anigenic types described in the present invention.
- the present invention is related to the use of the Hepai ⁇ isis Virus B surface anigen as immunopotentiator in nasal immunizations, with the vaccine formulations resulting from the combination of this antigen and other vaccine antigens that benefit from this property and with the application of this use of the Hepatitis B Virus surface antigen and formulations in the field of vaccines.
- mulfivalen ⁇ es formulations specifically for nasal administration, that result from the application of this property of HBsAg, which favors the increase of the immune response to the an ⁇ genous viruses present in them.
- the vaccine formulations for nasal administration of the present invention may contain one or more protein anigens of soluble nature, which receives an immunopotentiating effect by its co-administration with HBsAg.
- They can be: the ileal loxoid, the diphtheria or protein-polysaccharide conjugates, the saccharide portion of which corresponds to an anti-Haemophilus influenzae type b vaccine candidate, Neisser ⁇ a meningitidis polysaccharide C, pneumococcus pneumoniae vaccine polysaccharides, or in general one or more proteins. Recombinantly purified or soluble vaccines of interest.
- sulfivalenid formulations for nasal administration in which a vaccine candidate from the group of the inactivated microorganisms is added to the surface antigen of Hepailil B virus and that it receives an immuno-potentiating effect by its co-administration with the HBsAg.
- the vaccine antigen can be, the Bordetella pertussis bacterin, which receives an immunopotentiating effect by its co-administration with HBsAg or another vaccine antigen of this nature alone or as part of complex antigen combinations.
- Other vaccine antigens that may be contained are current inactivated or attenuated vaccine candidates.
- the formulations of the present invention can be solubilized in PBS, saline, water for injections or in any buffer solution for use in medical practice and that allow the stability of the anigens, in concentrations of anigens that are in the order of the possible combinations. of mass and volume described above.
- the anigenic components can be mixed with the HBsAg according to candidates of interest by age of the vaccination or by multivariate candidates based on any other premise, where one, two or more anigenic types of those previously described are represented and that can be targeted. lyophilized and administered by gofas, spray or pulverization.
- the vaccine formulations of the present invention can be used to achieve effective immunization of human or animals in a preventative or therapeutic manner.
- FIG. 1 Cinematic of the IgG response of an immunization scheme with inoculations on days 0, 14, 28 and 87. Blood draws were performed on days -10, 21, 35, 42, 84 and 97.
- A Kinetics the serum IgG anti HBsAg response
- B Kinetics of the anti-TT response in serum
- C Cinefica of the anii response DT in serum
- D Cinefica of the anlii response Bp in serum.
- Tables 1A, B, C and D results of the statistical analyzes of the comparisons between groups of the respective figures.
- the animal HBsAg titers generated by the group immunized with the Heberbiovac HB® vaccine (group 12) were significantly higher than those obtained with the immunization of any of the nasal groups. This result is due to the higher immunogenicity of HBsAg when it is inoculated by the IP route compared to the intramuscular and subcutaneous routes. This characteristic of the IP route has been evidenced in our experiments.
- the inoculation of 250 ⁇ L of the vaccine per mouse corresponding to the 5 ⁇ g dose of HBsAg -equivalent with the nasal dose-, required the use of the IP roller.
- a response that equates the response obtained by nasal inoculation with that obtained by IP inoculation has been found in older animals. An example of this was evident in the second scheme (see example 2), although the nasal candidates were different.
- HBsAg has a strong potentiating effect on both soluble proteins and vice versa, also showing in the case of DT a synergistic acitivity in terms of cross-potentiation of the immune response to antigens in mixtures, since as previously explained, the surface anigenic IgG anii response was enhanced when DT was added.
- the importance of adding Bp to the mixture could also be demonstrated once again, which allowed the anti-DT response to be increased hundreds of times, placing it at levels similar to those obtained after IP administration. It should be remembered at this point that the response is similar to that obtained by the IP route, despite the fact that in this way a quantity of DT five times higher was used.
- Example 2 Determination of the response in mucosa of the multivalent nasal formulations of HBsAg.
- blood titers were also no different in terms of IgG anti HBsAg as a result of the group's strong booster dose response with HBsAg in PBS.
- 20% more seroconversion was found for the first group. Although no differences were found, it is important that so much quantity of antigens does not affect the response in the vagina anfi HBsAg.
- the response generated by the group that received the four antigens via the nasal route was also higher than that generated in the teravalenia vaccine group intraperitoneally, similar behavior as with TT.
- the mucosally immunized groups developed significantly higher vaginal IgA levels compared to the group containing the four antigens by IP route.
- the levels of IgA anti DT for group 1 did not differ from those obtained by the groups that had higher immunogenicity, evidencing what was previously verified for TT, that HBsAg induced a highly significant potentiation of the anti DT response in the vagina. with respect to group 9, in which the toxoid was administered in PBS (Fig. 2C).
- Example 3 Comparison of the antibody response against FHA proteins and pertussis toxin after nasal and systemic administration of the formulations of groups 7 and 13 of Example 1.
- Lymphoproiferative response in the spleen after nasal administration In order to study the proliferative response generated in the spleen by the anigens of Example 1, groups 7 to 13 were selected on day 100, performing the spleen extraction of at least four mice per group, with which a pool of lymphocytes grown in the presence of the antigens with which they had been immunized.
- Figure 5 highlights the results of the evaluation of the proliferative capacity of the antigens administered by the nasal route in a tetravalent formulation, individually.

- Antigens can be selected that would be formulated by application according to age groups, according to their inoculation in the elderly, adolescents or newborns. Also for the interest of the type of mucosal diseases, here you can find antigens that penetrate through mucosa in which mucosal immunity is important. Among these, they can be selected according to the use of mixtures of anigens to prevent sexual, respiratory, or intestinal diseases. Serving risk groups, or the needs of travelers.
