Definitions
- the present invention relates to an improvement to vaccines containing alum in their compositions and in which the antigen may be partially or wholly absorbed onto alum.
- the improvement consists in the association in the constituent composition of these vaccines of 2 to 120 ⁇ g per kg of body weight or 0.1 to 6 mg per dose of muramyl peptide; these vaccines thus perfected have the particular advantage of conferring increased immunity so that the number of injections necessary for immunization is reduced.
- the only immunoadjuvants currently used in human vaccines are aluminum-based compounds such as aluminum hydroxide or aluminum phosphates.
- the active principle of which consists of an antigen obtained by m vitro genetic recombination, such as Havrix, a vaccine against hepatitis A, the active principle of which is an antigen obtained from a strain of hepatitis A virus cultured in cell culture, and containing aluminum hydroxide at a rate of 1.5 mg per dose (0.5 mg of aluminum) and marketed by the company Smith Kline & French (6, Esplanade Charles De Gaulle, 92731 Nanterre Cedex) under the trade name of Havrix. Two administrations conducted a month apart are used to induce seroconversion in 98% of individuals.

- Vaccines against hepatitis B mentioned above are effective after at least three injections at 0, 30, 60 or 180 days followed by a mandatory recall after one year, in addition to a number of topics are not very responsive or non-responsive In the total population they represent around 5% and the ability to obtain seroconversion depends very much on the subject's age, it is already significantly weaker from 30-35 years of age. particularly poorly responding groups are hemodialysis patients (30 to 45% of this population) and kidney transplant recipients, 75 to 95% of whom do not respond to vaccines.
- Ala-D-GIn-n-methyl-ester and Murametide or Nac-Mur-L-Ala-D-GIn methyl ester have already been developed in preclinical efficacy, acute, subacute and chronic toxicity tests as well as in phase 1 trials in humans; excellent tolerance was demonstrated following administration to over 200 subjects and 50 subjects Murabutide for Murametide
- the inventors have had the idea of associating peptides muramyls existing vaccines antigens formulated in the presence of alum.
- the adjuvant doses contain an amount between 2 and 120 ⁇ g per kg of body weight, or 0.1 to 6 mg per unit dose of water-soluble muramyl peptide of formula •
- the muramyl peptide of the invention is l one of those entering the above formula in which the group R is a methyl group and the group R2 is a group
- MDP derivatives are murabutide, murametide, muradimetide or MDP-threonyl
- MDP-L-Lys-GDP Nac-Mur-L-Lys-D- iso Gin glyceryl-sn-dipalmitoyl
- the preferred adjuvant doses are 6 to 60 ⁇ g per kg of body, that is, for a 50 kg person 0.3 to 3 mg per vaccinating dose.
- the invention therefore relates to hepatitis vaccines absorbed on alum and improved by the combination of 2 to 120 ⁇ g per kg of body weight or 0.1 to 6 mg per vaccinating dose, preferably 6 to 60 ⁇ g per kg or 0.3 to 3 mg per dose, either of a compound of formula (I) or MDP-Lys - GDP
- the vaccines of the invention can in particular be improved by a derivative of formula (I) in which
- the group R is a methyl group
- the group R 2 is an NH 2 group and more particularly still the murabutide the murametide, the muradimetide the MDP-threonine or the MDP-Lys-GDP
- a vaccine according to the invention is characterized in that it contains a recombinant hepatitis B antigen, it can act
- the hepatitis B vaccines of the invention preferably contain as antigen vaccinating the S region and all or part of the pre-S region, in particular the pre-S2 region of the virus surface antigen
- the invention also relates to a method for manufacturing a vaccine having increased immunogenicity, characterized in that said vaccine consists of antigens absorbed on alum or formulated in a composition containing alum and in which are added 2 to 120 ⁇ g per kg of body weight or 0.1 to 6 mg per vaccinating dose, preferably between 6 and 60 ⁇ g per kg or 0.3 to 3 mg per muramyl vaccinating dose peptide of formula (I) above or MDP-Lys- GDP
- the derivative of the muramyl peptide is chosen from murametide, murabutide, muradimetide, threonyl MDP.
- the process of the invention makes it possible to manufacture improved vaccine compositions against hepatitis B, and also makes it possible to manufacture mixed vaccine compositions allowing to vaccinate a population at the same time against the hepatitis B virus or any mixed vaccine provided that it contains the recombinant antigen against hepatitis B and in particular a mixed vaccine hepatitis A + B or hepatitis A + B + C, as soon as their formulation contains alum
- the invention relates to the use of 2 to 120 ⁇ g per kg of body weight or 0.1 to 6 mg per dose and preferably from 6 to 60 ⁇ g per kg of weight or 0.3 to 3 mg per vaccinating dose of a muramyl peptide of formula (1) above or of MDP-Lys-GDP, to improve the immunogemicity of a vaccine composed of recombinant
- a vaccine comprising at least one hapten as a vaccinating antigen also forms part of the invention, as well as the vaccines containing as immunogen at least one hapten coupled or not with a carrier molecule Vaccines comprising at least one hapten and at least one recombinant antigen, one of them being absorbed on alum, associated with a muramyl peptide derivative, form part of the invention
- T cells capable of proliferating in the presence of the antigen which have therefore been sensitized specifically to it are the cells responsible for the establishment of the immune memory. It is thanks to them that the vaccinated individual can immediately respond to aggression by the virus against which he sought to acquire protection It is therefore essential to offer a vaccine capable not only of inducing antibodies in the long term but also of memory T cells This allows vaccinated individuals to benefit from two lines of immune defense
- FIG. 1 represents the proliferation of T cells measured by incorporation of tritiated thymidine, as a function of increasing quantity of hepatitis antigens.
- Example 1 increase in specific T cells
- the surprising effect obtained, and in particular that of rendering a currently non-immunogenic vaccine immunogenic in certain categories of the population, may be linked to the specific increase in a proliferative T-cell response.
- This increase in the number of T cells sensitized to l antigen also makes it possible to evaluate the level of immunological memory which has been induced. This is illustrated by the following experiment. Mice were sensitized to the hepatitis B virus surface antigen, the proliferation of T cells was measured by incorporation of tritiated thymidine after incubation with the antigen present in the culture medium.
- balb / C mice received 5 ⁇ g of HBS antigens by subcutaneous injection at the base of the tail in 0.1 ml of PBS buffer with or without adjuvants
- the T lymphocytes were grown in PBS. or with increasing doses of HBS antigens as indicated on the abscissa.
- the proliferative response was measured by incorporation of tritiated thymidine
- the results of figure (I) are indicated as the average number of strokes per minute in t ⁇ plicates
- Lys-GDP in the presence of alum can also be demonstrated by a relative increase in the response to specific immunoglobulins following the vaccination effect.
- a hepatitis B recombinant vaccine absorbed on alum was used.
- Various experiments have been carried out either on Swiss mice or on Balb / C mice, they constantly demonstrate the effect of the addition of murabutide on the Hepatitis B vaccines absorbed on alum.
- Table 1 represents the cumulative results obtained in 6 similar experiments The anti-HBS antibody titers are expressed in milli-units per ml as a function of time A control group received two vaccinations, a second control group received three vaccinations and an experimental group received two injections of the vaccine supplemented with murabutide Table 1
- the Swiss mice (8 per group) received by subcutaneous injection 1 ⁇ g of HBS antigen and 135 ⁇ g of alum with or without 100 ⁇ g of murabutide on day 0 They receive a booster injection on day 30 On day 60 only on control group with alum and without murabutide receives a third injection Antibodies are measured by EIA
- Balb / C mice (8 per group) received by subcutaneous injection 1 ⁇ g of HBS antigen and 135 ⁇ g of alum with or without 100 ⁇ g of murametide on days 0 and 30. Antibodies are measured by ELISA on days 28 and 54.
- HBS + alum (Control) 10,700 HBS + alum + Muradimetide 60 2,250 HBS + alum + MDP-Lys-GDP 35 2,600
- the invention can also be applied to other antigens as shown in Example 5.
- the antigen is a conjugate containing the ⁇ chain of cho ⁇ ogo ⁇ atrope hormone (hCG) coupled to the anatoxme toxoid (TT) (20% ⁇ HCG in the conjugate)
- hCG cho ⁇ ogo ⁇ atrope hormone
- TT anatoxme toxoid
- Balb / C mice received subcutaneously 10 ⁇ g of ⁇ HCG conjugated to anatoxme
- the antigen was administered either alone or in a Freund's Incomplete emulsion (FIA) or with alum (200 ⁇ g ) either with Murabutide (100 ⁇ g) or with alum and Murabutide Antibodies combining with HCG were measured by ELISA on day 20
- the conjugate ⁇ HCG-TT is administered absorbed on alum and the results obtained shown in table 4 ci -after
- Example 5 The data obtained in Example 5 are very much reinforced by those described in Example 6 below.
- Example 6 Haptene-carner system where the muramyl peptide / alum association makes it possible to obtain high antibody titers but especially biologically active antibodies essential result for successful vaccination
- Example 6 the purpose of the vaccination is to obtain antibodies capable of neutralizing the biological activity of a hormone
- This hormone is a decapeptide produced by the hypothalamus and is absolutely not immunogenic Even after coupling on a carrier molecule "Carrier", it is unable after several injections to induce the production of a significant level of antibodies.
- LH-RH The hormone considered called Luteineizmg Hormone - Releasing Hormone or LH-RH is synthesized centrally in the hypothalamus and following a cascade of interactions, it fully controls the synthesis of sex hormones in the male or female and in particular the production of testosterone Consequently, LH-RH controls the development and functioning of the testes, prostate and seminal vesicles If the level of LH-RH is low but especially for what interests us, if its activity is neutralized by biologically active antibodies, there is a decrease in the level of circulating testosterone and mvolution of the sexual organs II has been shown by many authors and in all the tested species (mouse, rat and guinea pig, cattle), that a conjugate LH-RH on tetanus toxoid (LH-RH-TT) only allows biologically active antibodies (i.e.
- Examples 5 and 6 described above show that the association of muramyl peptides with antigens absorbed on alum is particularly advantageous in the case where the vaccinating principle is a hapten requiring coupling with a carrier molecule This case can arise when the the vaccinating principle is a peptide, a weakly immunogenic protein or a sugar.
