PREREQUISITES TO the CREATION of INVENTIONS

Meningitis is an inflammation of the tissues that cover the brain and spinal cord. He may have a bacterial or viral; bacterial meningitis is usually more severe.

The main causative agent of bacterial meningitis is Neisseria meningitidis (the meningococcus), however, other existing pathogens of meningitis include Streptococcus pneumoniae (pneumococcus), Haemophilus influenzae (Hib) and Streptococcus agalactiae (GBS). N.meningitidis causes meningococcal septicaemia, which is a main feature of infection, a life-threatening.

Vaccine for protection against infection Hib exist for many years. The vaccine, which protects against meningococcus serogroup C ("MISP"), was introduced in several European countries in 1999-2000-pneumococcal vaccine, it has become customary in America in 2000

Vaccines against the three pathogens based on antigenic capsular polysaccharides are conjugated to protein carriers to enhance the immunogenicity of polysaccharides. These vaccines is lead by injection, although there have been described studies in mice on delivery via the mucous membrane, for example, reference 1 describes intranasal introduction of conjugate Hib vaccines, and reference 2 describes intranasal introduction of conjugate vaccines MISP (see also reference 3). Delivery of vaccines through the mucosa is an attractive approach to overcome the problem of the large number of injections that produce small children. In addition, since most pathogens first infect the surface of the mucous membranes, the acquisition of immunity to the mucosa at the site of infection may contribute to optimal protective immunity.

Also described intranasal and oropharyngeal delivery of vaccines against meningococcus serogroup B ("MAV") [e.g., reference 4], as well as intranasal delivery of bacteria .pertussis that Express transferrin-binding protein In N.meningitidis [5]. In publication 6 described intranasal delivery of pneumococcal conjugated vaccines [see references 7 and 8].

The aim of the present invention to provide an improved delivery of vaccines against meningitis through the mucous membrane.

Description of the INVENTION

The present invention relates to compositions for delivery via the mucous membrane, containing two or more of the following agents: (a) the antigen is which induces an immune response against Haemophilus influenzae; (b) an antigen which induces an immune response against Neisseria meningitidis; and (C) an antigen which induces an immune response against Streptococcus pneumoniae.

The combination of different antigens reduces the number of doses that must be entered for the purpose of immunization against multiple pathogens. This is usually represented as an advantage for vaccines administered by injection, when the number of painful injections decreases, but this is less important for vaccines delivered through the mucous membrane (for example, intranasal vaccine), due to less pronounced discomfort associated with delivery. However, the combined antigenic compositions are advantageous even for delivery via the mucous membrane, as is improving the patient's compliance regime and schemes of vaccination, and facilitated the transportation and storage of medicines.

Although the Association of antigens in a single dose is attractive [for example, links 9-12], it presents difficulties because of the interactions between the various components after the merger, especially in liquid compositions [13]. Emerging issues include the interaction of antigens, competition antigens [14, 15], the degradation of antigens, inhibition of epitopes and compatibility with adjuvants. Quality control mixtures is also more t is odnim. In addition, existing knowledge in the field of combining antigens are vaccines, which are administered by injection, and not through the mucous membrane.

Despite these difficulties, the applicants have unexpectedly found that the antigens of Haemophilus influenzae, Neisseria meningitidis and/or Streptococcus pneumoniae can be combined for delivery via the mucous membrane without negative consequences that could be expected. Combining antigens of the three microorganisms is also advantageous because it allows a single dose to deal with three separate causes of common diseases, namely, bacterial meningitis. Messages about combined meningitis vaccines of this type had previously [16], but about delivery via the mucous membranes have been reported.

Shipping through the mucous membrane

The composition according to the invention is intended for delivery via the mucous membrane.

From all the available paths for delivery via the mucous membrane of the intranasal route is the most practical, since it is connected with easy access using relatively simple devices that are already being produced on an industrial scale. In addition, intranasal immunization is more effective compared with alternative ways. Thus, the preferred route for delivery through slit the out shell is intranasal path, and composition according to the invention is preferably adapted for intranasal, such as the introduction through a nasal spray, nasal drops, gel or powder [for example, references 17 and 18].

Alternative routes for vaccine delivery via the mucous membranes are oral, intragastric, lung, putting, rectal, ocular and vaginal path.

(A.) Antigen Haemophilus influenzae

Antigen H.influenzae in the composition will usually be a capsular charigny antigen. Sacharine antigens from H.influenzae b is well known.

Advantageously, if the Hib saccharide covalently anywhereman with protein carrier to enhance its immunogenicity, especially for children. Production of polysaccharide conjugates in General and capsular polysaccharide Hib, in particular, is well documented [e.g., links 19-27, etc.]. In the present invention can use any suitable conjugate Hib.

Sahariana part of the conjugate may be a polysaccharide (e.g., polyribosylribitol (PRP) full length), but it is preferable to carry out the hydrolysis of polysaccharides (e.g., acid hydrolysis) to obtain oligosaccharides (for example, with molecular mass from ~1 to ~5 kDa). If you are hydrolysis, the hydrolysate can be sorted by size to remove too short oligos Aridi, which are not full immunogenum. Divided according to the size of the oligosaccharides are preferred sharedname antigens.

Preferred protein-carriers are bacterial toxins or toxoids, such as diphtheria or tetanus toxoids. The latter are widely used in conjugated vaccines. Diphtheria toxoid CRM197 is especially preferred [28]. Other suitable carrier proteins include protein N.meningitidis outer shell [29], synthetic peptides [30, 31], heat shock proteins [32, 33], pertussis proteins [34, 35], protein D from H.influenzae [36], cytokines [37], lymphokines [37], hormones [37], growth factors [37], toxin a or b from .difficile [38], proteins, exciting iron [39], and the like, it is Possible to use mixtures of proteins vehicles.

Sharenow part directly or through a linker to konjugierte with protein carrier. A direct connection can be made by oxidation of the polysaccharide followed by reductive amination using protein, as described, for example, in references 40 and 41. Communication through the linker group can be accomplished using any known procedure, for example, procedures described in the links 42 and 43. Suitable linkers include carbonyl, adipic acid, In propionamido [44], nitrophenylamino [45], halogenoalkane[46], glycosidic bonds [47], 6-aminocaproic acid [48], ADH [49], the part from4to C12[50], etc.

Before conjugation saccharide will usually be activated or functionalized. Activation may include, for example, Cinelerra reagents, such as CDAP (for example, tetrafluoroborate 1-cyan-4-dimethylaminopyridine [51, 52]. Other suitable methods are used carbodiimide, hydrazides, active esters, norburn, p-nitrobenzoic acid, N-hydroxysuccinimide, S-NHS, EDC, TSTU; see also the introduction to the reference 53). The preferred technique is reductive amination.

The preferred conjugate comprises a Hib saccharide covalently linked to CRM197 via amber diapir adipic acid [54, 55].

Compositions according to the invention can include more than one antigen Hib.

(b) Antigen of Neisseria meningitidis

Antigen N.meningitidis in the composition will usually be a capsular charigny antigen (for example, from serogroups a, C, W135 or Y). Sacharine antigens from N.meningitidis well known. In the case of antigen from serogroup b, however, it is preferable that the antigen was a protein antigen, because the native capsular polysaccharide Mepv contains autoantigens. If you want to use charigny antigen from serogroup B, it is preferable to use a modified sugar is command antigen [for example, links 56, 57, 58], for example, an antigen, a modified N-Propionibacterium. Possible chemical modification of saccharides from other serogroups.

The saccharide is preferably an oligosaccharide, i.e. a fragment of the capsular polysaccharide. Polysaccharides can be processed with getting shorter oligosaccharides, and the latter can be obtained by cleaning and/or sorting by size of native polysaccharides (for example, by hydrolysis in a weak acid, by heating, by chromatography sorted by size and the like). Preferred oligosaccharides MISP described in the links 59 and 60.

The saccharide is preferably kongugiruut with protein carrier, as described above.

Compositions according to the invention may include more than one meningococcal antigen. Preferred may be the inclusion of capsular sharidny antigens of at least two (i.e. 2, 3 or 4) of serogroups a, C, W135 and Y of N.meningitidis [61].

When the mixture includes capsular saccharides from both serogroups a and C, it is preferable that the ratio (wt./mass.) saccharide Mopa: saccharide MISP was greater than 1 (e.g., 2:1, 3:1, 4:1, 5:1, 10:1 or above). Unexpectedly observed improved the immunogenicity of the component Mopa, when he was present in excess (weight/dose) in relation to a component of the MISP [61].

When the mixture consisted of capsular Saha is the ides of serogroup W135 and at least one of the serogroups A, C and Y, it has been unexpectedly found that the immunogenicity of the saccharide MenW135 above in the introduction, in combination with a saccharide (sugar) from the other serogroups (serogroups)than when introduced separately (in the same dose, etc.) [61]. Thus, the ability of antigen MenW135 to cause a more intense immune response than the immune response induced by an equivalent amount of the same antigen when delivered out of touch with antigens from other serogroups. Such enhanced immunogenicity can be determined by injection of the antigen MenW135 the control animals, but a mixture of experimental animals and comparing antibody titers against these two immunogens using standard surveys such as the titles of bacteria, radioimmunoassay analysis, ELISA and other Vaccines containing synergistic combinations of saccharides from serogroups W135 and other serogroups have immunological advantages, because they reinforce anti-W135-answers and/or lower dose W135.

When used protein antigen from serogroup B, it is preferable to use one of the proteins described in the links from 62 to 71. Preferred protein, antigens include protein "287" or its derivatives (for example, ΔG287).

It is also possible to use the antigen from outer membrane vesicles (OMV) for serogroup In [for example, 72, 73].

Compositions according to the invention may include SEB is more than one meningococcal antigen.

(C) Antigen of Streptococcus pneumoniae

Antigen S.pneumoniae in the composition will usually be a capsular charigny antigen, which is preferably anywhereman with protein carrier, as described above [e.g., 74, 75, 76].

It is preferable to include saccharides from more than one serotype S.pneumoniae. For example, widely used mixture of polysaccharides from 23 different serotypes, as well as conjugated vaccine polysaccharides from 5-11 different serotypes [77]. For example, PrevNar™ contains antigens from seven serotypes (4, 6B, 9V, 14, 18C, 19F and 23F), each saccharide separately anywhereman with CRM197 by reductive amination.

Compositions according to the invention can thus contain more than one pneumococcal antigen.

Available are also other adjuvants for mucosal [for example, see Chapter 7 references 85].

Preferred adjuvants for mucosal are bacterial ADP-reboilers toxins or their mutants. For example, cholera toxin (CT) or thermo-labile toxin of E. coli (LT) are efficient adjuvants for mucosal and their detoxificaton twins [86]. ST and LT are homologous and are usually interchangeable.

Detoxification ST or LT can carry chemical or, preferably, genetic means.

When the components are in a mixture, they will all be in lyophilized form or in solution/suspension. Lyophilized components will be resuspendable (e.g., buffer) before the introduction of the patient. Components such as adjuvants may be present in the buffer or in dried material.

Immunogenic compositions

The composition according to the invention preferably is an immunogenic composition (e.g., vaccine). Preparation of vaccines based on saccharides or saccharide conjugates protein is well known to specialists.

Immunogenic compositions include immunologically effective amount of antigens, as well as any other listed components, if necessary. By "immunologically effective amount" is meant that the introduction of a specified number of the individual, as a single dose, or as part of a series, is effective for treatment or prevention. This number varies depending on the health and physical status of the individual being treated, age, the taxonomic GRU the dust of the individual, being treated (e.g., Primate, non-human, Primate, and the like), the ability of the immune system of an individual to synthesize antibodies, the desired degree of protection, vaccine composition, evaluation by the attending physician clinical situation and other factors. It is expected that this amount will fall in a relatively broad range that can be determined by the usual tests.

Methods of treatment

Another preferred class of patients are adult women and especially women of childbearing age or pregnant women. Compositions according to the invention are particularly suitable for passive immunization of children through the mother's body.

The antigens in the compositions induce immune responses against certain bacteria. These immune responses are preferably protective, i.e. they protect the patient from further infection by bacteria. Thus, compositions according to the invention is preferably used for the prevention (i.e. to prevent infection), although they can also be used for therapeutic purposes (i.e. to treat disease after infection). Immune response preferably is clucalc in itself the production of bactericidal antibodies in a patient.

The present invention relates to a method for producing an immune response in a patient, comprising the administration to the patient of the vaccine through the mucous membrane (e.g., intranasal). The immune response is preferably protective against bacterial meningitis and/or bacteremia caused by Haemophilus influenzae, Neisseria meningitidis and/or Streptococcus pneumoniae. Individual antigenic components of the compositions is preferably introduced simultaneously and in combination. In other embodiments, implementation of the present invention, however, they can be administered separately, simultaneously or sequentially. In the case of the introduction of the smaller components are preferably delivered to the same surface of the mucous membrane.

WAYS of IMPLEMENTATION of the PRESENT INVENTION

The combined composition Hib/MenC

Capsular oligosaccharide With serogroup of Neisseria meningitidis was obtained by selective activation of the reducing end groups sorted by size of the oligosaccharide. The same method was used for Haemophilus influenzae type B. Sugars conjugatively with protein carrier CRM197 via a hydrocarbon spacer [139] (Chiron Siena, Italy). The conjugates were diluted with saline phosphate buffer (PBS) and the volume of inali (i) mutant thermolabile enterotoxin E. coli LTK63 or LTR72, (ii) with aluminum hydroxide (Superfos Biosector a/s) or (iii) by cholera toxin (CT) from Sigma. For the combined introduction of the above composition was mixed before use.

The introduction of the composition through the mucous membrane

Simultaneously conducted two identical studies on the introduction. Groups of 10 female BALB/C mice aged 6-10 weeks were immunized intranasally 10 µg MISP or no Hib separately, in combination with CT (1 μg) or with mutant LT (1 µg and 10 µg). For comparison, an additional group of mice were immunized/m 10 ág MISP or Hib adsorbed on Alum. Compositions were made on the day of immunization, the mice were immunized at 0, 21 and 35 day. 50 μl of the compositions were injected with hip or buried into different the nostrils of mice under anesthesia. Blood samples were taken on day 49, together with samples of swabs from the end portion of the nasal cavity (NW).

In order to assess, is not violated if the immunogenicity of the conjugates by mixing two vaccines, conducted at the same time the third study, in which two vaccines were administered simultaneously to the same group of mice, in the same doses and according to the same scheme as described above.

Immunological responses to composition

Or antibody-based test answers against the conjugate MISP was determined by ELISA using a modified method as described previously [140]. KRA is to, tablets for ELISA were covered with a saccharide MISP, derivational adipinate dihydrazide, over night at 4°C. antibodies were detected using HRP-conjugate goat artemisinin IgG and horseradish peroxidase. Titers of IgG antibodies against MISP test samples and internal control was expressed as the reciprocal serum dilution giving OP=1,0. Each serum sample was analyzed in duplicate, and used the average value to calculate the geometric mean and standard deviation within the standard error. Or antibody-based test answers against Hib PRP was determined similar to ELISA for the MISP way, except that the tablets were covered with PRP, conjugated with BSA (PRP-BSA). Titers were expressed as OD450 nmfor serum, diluted 1:50.

Conducted analysis of swabs from the nasal cavity to IgA against the MISP using bioluminescent analysis (BIA) [141]. Briefly, we used the same reagents and procedure coverage for the measurement of IgG against the MISP in the serum. Then as the first antibody was added specific biotinylated goat antimurine IgA. Titers represent logarithmic values of breeding, extrapolated from data log RLU shut-off value, calculated by at least two standard deviations above the average background.

Mediated by the complement system is a bactericidal activity against bacteria MISP was measured in pooled serum samples, as was previously described [140]. Titers were determined by calculation of the serum dilution required to achieve a 50% reduction in the number of CFU after incubation for 1 hour.

On figa shows the geometric average titers of serum IgG antibodies against the MISP alone (not shaded bars)and in combination with Hib antigen (shaded bars). Serum or antibody-based test answers, caused both mutants LT were significantly higher responses to antigen alone. LTR72 demonstrated more pronounced adjuvant properties than LTK63, in lower doses. Most notably, or antibody-based test responses induced by intranasal immunization with both LT mutants were compared with the responses obtained when using ARTICLE wild-type or responses induced by intramuscular immunization with a vaccine using the adjuvant alum. It is important that adding a second conjugated Zaharenko antigen does not adversely impact on or antibody-based test answers against each of the antigens.

On FIGU shows the geometric average titers of serum IgG antibodies against saccharide Hib PRP. As in the case of the MISP, or antibody-based test answers, caused by both LT mutants were higher than responses to the antigen alone. And again, LTR72 demonstrated more pronounced adjuvant properties. Against the appropriate titers were induced in mice immunized intranasally mutants LT, and vaccine using adjuvant alum intramuscular immunization. In addition, no data on competition after combined intranasal immunization two sharedname conjugated vaccines;

the responses induced against Hib in combination with the MISP, were comparable to responses induced by immunization with Hib separately.

Levels of bactericidal antibodies induced by intranasal immunization with LT mutants, was strongly correlated with serum IgG responses by ELISA results, and again were comparable to responses induced ARTICLE, or intramuscular immunization vaccine, adsorbed on alum (figure 2).

Samples obtained from swabs of the nasal cavity after intranasal immunization MISP with both the LT mutants showed higher titers of IgA than samples obtained intranasal immunization in the absence of adjuvants (figure 3). As expected, intramuscular immunization caused a very low titers of IgA.

Conclusion

A powerful serum or antibody-based test answers against N.meningitidis and H.influenzae can be induced by intranasal immunization with conjugated vaccines in combination with adjuvants for insertion through the mucous membrane. In addition, in the case of antigen MISP, antibodies, induced by intranasal immunization, have m is Snoy bactericidal activity, which is known to correlate with protective immunity [142]. In addition, the IgA responses in the nasal cavity were induced only in animals immunized by intranasal. The induction of secretory immunity is important, because the upper parts of the respiratory system are the input gates for several pathogens, including N.meningitidis and .influenzae.

Based on the antibody titers obtained with the use of conjugated vaccines administered separately or in combination, and on the basis of bactericidal activity, measured against the MISP, it can be concluded that the combination of the two vaccines administered in conjunction with adjuvant for mucosal, does not adversely impact on or antibody-based test answers against the MISP or Hib. Thus, the results suggest that intranasal immunization is an effective way of immunization for conjugated vaccines, polysaccharide-protein in combination with adjuvants for mucosal, such as mutants of LT.

For reliable increase the immunogenicity of both conjugated vaccines administered at the same time, it was quite the same dose of LT mutants. This is particularly important as this should reduce the number of required adjuvant and the risk associated with potential toxicity. It is important that the existing immunity against Muta is the LTK63 does not affect the ability of the mutant to act as an adjuvant for the second antigen [2]. In addition, the effectiveness of the vaccines delivered through the mucous membrane, can be further improved by making vaccines in bioadhesive delivery systems [91].

In conclusion we can say that the combination of conjugated vaccines, polysaccharide-protein mutants LT for intranasal immunization is an effective approach to immunization through the mucous membrane for pediatric purposes.
