Definitions
- the present invention relates to a vaccination kit intended to induce in a mammal, a protective immune response against a pathogenic organism infecting mucous membranes.
- lymphocytes migrate into the secondary lymphoid organs.
- the latter can be sites inducing systemic immunity or mucosal immunity. They can thus be called “systemic” or “mucous" organs.
- the spleen which responds to antigens entering the bloodstream and the peripheral ganglia which provide protection against antigens entering the anatomical area from which they provide lymphatic drainage.
- the immune system associated with the mucous membranes for its part, protects the body against antigens entering and residing in the mucous epithelial surfaces.
- the immune system associated with the mucous membranes (inducing sites) is presented in the table below:
- Immunoglobulins type A constitute the majority of immunoglobulins on the surface of the gastrointestinal, respiratory, urogenital or other mucous membranes. They are secreted within these mucous membranes and reputed to confer protection against infections affecting these sites.
- a mucosal immune response is usually obtained after immunization by mucosal route, either directly at the level of the effector mucosa, or at another mucosal site distant from the site where to fight the infection.
- the mucosal routes which are a priori accessible for immunization are the oral route, the intragastric route, the nasal route, the urogenital route and the rectal route.
- the oral route is the one that is preferred, because of its ease of use, whether to vaccinate against infections of the gastrointestinal mucosa or to vaccinate against infections affecting another mucosa.
- Jertborn et al. Vaccine (1992) 10: 130 relates a cholera vaccination study carried out with a small group of Swedes. The vaccine was administered twice, as an oral liquid solution. This vaccine has been shown to be both effective and safe. Nasal influenza vaccination has been successfully implemented in children and adults, as reported by Anderson et al, J. Clin. Microbiol. (1992) 30: 2230 and Treanor et al, Arm. Inter. Med. (1992) 117: 625.
- rectal route may be a common route of entry for the entire mucosal immune system and that it should be possible to induce an immune response mucosal at a site distant from the rectal mucosa, used as an entry route to
- mice receive the antigen intramuscularly and intragastrically using a tube, under anesthesia.
- Hartman et al, Infect. Immun. (1994) 62 (2): 412 describes several immunization protocols against Shigella.
- one of them comprises a first injection by the intraperitoneal or subcutaneous route followed by a booster by the ocular route.
- This protocol is tested in the guinea pig model of keratoconjontivitis. The authors show that in naive animals, mucosal immunization is necessary for the induction of protection. Parenteral and mucosal double immunization increases the level of protection.
- Nedrud et al J. Immunol. (1987) 139: 3484 describes a method of immunization against Sendai virus infections (nasopharyngeal infections which may eventually develop into bronchitis and pneumonia).
- the effector site at which the immune response could be sought by the implementation of this method, is therefore the entire respiratory tract.
- the method of Nedrud et al comprises two major steps: a primary immunization by the oral (intragastric) route and a booster via the nasal route.
- the oral (intragastric) route is not the optimal route which would allow an inducing agent (here the Sendai virus) to reach one of the inducing sites of an immune response in the respiratory tract.
- the subject of the present invention is a pharmaceutical composition intended to induce in a host mammal, a protective immune response against an antigen, at the level of an effector mucosal site, which comprises at least two identical products. or different containing each an agent inducing the immune response selected from the antigen and provided that the antigen is of a protein nature, an expression cassette capable of expressing the antigen, for concomitant or consecutive administration; one of the products being formulated so as to be administered via the nasolabial route so that the inducing agent is targeted towards the site (s) inducing an immune response at the level of the nasopharynx or salivary glands, the other product being formulated to be administered via an appropriate mucosal route other than the nasal route, so that the inducing agent is targeted towards the inducing site (s) of a immune response at the effector site where the immune response is sought.
- the pharmaceutical composition according to the invention comprises a third product, identical or different to the first two, which contains an agent inducing the immune response, selected from the antigen and provided that the antigen is of protein nature.
- the subject of the invention is a kit for inducing in a host mammal, a mucosal immune response against an antigen, at an effector site, which comprises: (i) so optional, a first agent inducing the immune response selected from the antigen and. provided the antigen is protein in nature. an expression cassette capable of expressing the antigen, a DNA or RNA fragment encoding the antigen; and (ii) a second and a third agent inducing the immune response selected from the antigen and. provided the antigen is protein in nature. an expression cassette capable of expressing the antigen, a DNA or RNA fragment encoding the antigen; with (a) optionally, instructions for systemic administration. of the first inducing agent,
- the invention also relates to a method for inducing, in a host mammal, an immune response against an antigen, at a mucosal effector site, according to which, in any order:
- a second agent inducing the immune response selected from the antigen is administered to the host mammal.
- the antigen is of a protein nature, an expression cassette capable of expressing the antigen, a DNA or RNA fragment coding for the antigen, via the nasal and / or buccal (nasal) route;
- a third agent inducing the immune response selected from the antigen is administered to the host mammal and, provided the antigen is of protein nature, an expression cassette capable of expressing the antigen, a fragment DNA or RNA encoding the antigen, by the appropriate mucosal route other than the nasal route so that the antigen is targeted to the site (s) inducing the immune response at the site effector where the immune response is sought.
- the administration of the first inducing agent can advantageously be carried out in a single dose, by systemic injection, such as an intravenous, intramuscular, intra-dermal or subcutaneous injection.
- systemic injection such as an intravenous, intramuscular, intra-dermal or subcutaneous injection.
- site and injection route will depend in particular on the lymph nodes that one wishes to target. We indicate that if we want to target the lymph nodes for example celiac, it is best to inject in the dorso-lumbar region using the intramuscular route (rather than the subcutaneous route).
- this inducing agent must be in particulate form.
- the inducing agent is advantageously supplemented with an adjuvant, either by precipitation or by adsorption.
- the adjuvant can be any conventional adjuvant of the aluminum phosphate or hydroxide type, calcium phosphate, or even an adjuvant such as polyphosphazene. It can also be an adjuvant of the liposome, microsphere, ISCOM or virus-like-particles (VLPs) type; the latter being of a particularly advantageous use when it is desired to target the ganglia which drains the urogenital region. All these adjuvants are within the reach of those skilled in the art.
- the appropriate dosage varies according to certain parameters, for example the individual treated or the nature of the inducing agent. For all practical purposes, it is indicated that a dose of an antigen can vary from 5 to 100 ⁇ g, preferably from 25 to 50 ⁇ g.
- nasolabial or buccal
- oral route should not be confused with what is commonly called “oral route” and which should be more aptly called “intragastric route”.
- the oral route including the intragastric route, must allow the inducing agent (antigen) to reach mainly the mucous membranes of the lower parts (digestive tract and mainly the small intestine and Peyer's patches). while the buccal route carries the inducing agent essentially towards the mucous membranes of the upper parts.
- the entry site of the oral route and that of the oral route can be the same; in this case it is the mouth. However, the trajectories are essentially different.
- the third inducing agent When it comes to the stomach or the intestine, the third inducing agent will advantageously be formulated to be administered orally, including the intragastric route (eg in the presence of enteric protection, such as liposomes, microspheres , bicarbonate or gelatin capsule).
- enteric protection such as liposomes, microspheres , bicarbonate or gelatin capsule.
- the third inducing agent In the case of the intestine or the urogenital tract, the third inducing agent will advantageously be formulated to be administered by the urogenital route, for example in the form of a vaginal capsule or by the rectal route, for example under suppository form.
- the second or third inducing agent may also be supplemented with an adjuvant other than liposomes or microspheres, and devoid of toxicity other than the non-toxic subunits or the detoxified forms of bacterial toxins.
- the adjuvant of the second or third inducing agent is used, the major lipopolysaccharide (MPLA: major lipopolysaccharide antigen) of a bacterium, for example of E. coli, Salmonella minnesota, Salmonella typhimurium or Shigellaflexneri.
- MPLA major lipopolysaccharide antigen
- MPLA mucosal adjuvant for the preparation of a composition (i) containing an antigen or, provided that the antigen is of a protein nature, an expression cassette capable of expressing the antigen, a DNA or RNA fragment coding for the antigen, (ii) intended for the induction of a mucosal immune response against the antigen and (iii) intended to be administered by mucosal route.
- the second or third inducing agent when it is an antigen, can be administered at a rate of 100 ⁇ g to 1 mg per dose.
- the first inducing agent (systemic route), when administered, is administered by primary injection, allowing a period of 7 to 45 days to run, preferably 20 to 30 days before the first booster (administration of the second or of the third inducing agent).
- the first inducing agent can also be administered at the same time as the second or third inducing agent.
- the second and third inducing agents can be administered concomitantly or consecutively. When administered over a period of time, they are advantageously administered from 7 to 45 days, preferably 28 days apart.
- each of the three inducing agents is carried out independently of each other.
- at least one of the three must be the antigen.
- these three inducing agents can be the same and in this case, it will advantageously be the antigen.
- a vaccine vector eg poxvirus or adenovirus comprising a DNA fragment coding for this antigen and placed under the control of an appropriate promoter
- this DNA fragment as it is (non-vectorized), put in plasmid form or not (preferably the DNA fragment will be inserted in a plasmid rather than remaining in the state of simple transcription unit), presented in formulation liposomal (anionic or cationic) or not, (iii) or the corresponding RNA fragment.
- a promoter capable of inducing in mammalian cells the expression of the DNA fragment coding for the antigen is used.
- DNA-based vaccines to be distinguished from vaccines based on viral vectors
- hCMV human cytomegalovirus
- use will preferably be made of a plasmid incapable of replicating in mammals. Such a plasmid must also be essentially non-integrative.
- the antigen of a bacterium pathogenic for the host mammal is an H antigen.
- pylori for example the apoenzymatic form of H urease.
- the invention also relates to the use of a DNA fragment coding for a H. antigen. pylori. in the manufacture of a composition intended to prevent or treat an infection with H. pylori and intended to be administered by nasal or nasal route.
- the DNA fragment used as a vaccine agent meets the criteria set out above.
