Definitions

  • the present invention relates to bacterial polysaccharide antigen vaccines, their manufacture and the use of such polysaccharides in medicines.
  • A vaccines comprising a pneumococcal polysaccharide antigen, typically a pneumococcal polysaccharide conjugate antigen, formulated with a protein antigen from Streptococcus pneumoniae and optionally a Th1 inducing adjuvant;
  • B specific, advantageous pneumococcal polysaccharide conjugates adjuvanted with a Th1 adjuvant;
  • C bacteria polysaccharide conjugates in general conjugated to protein D from H. influenzae.
  • Streptococcus pneumoniae is a Gram-positive bacteria responsible for considerable morbidity and mortality (particularly in the young and aged), causing invasive diseases such as pneumonia, bacteremia and meningitis, and diseases associated with colonisation, such as acute Otitis media.
  • the rate of pneumococcal pneumonia in the U.S. for persons over 60 years of age is estimated to be 3 to 8 per 100,000. In 20% of cases this leads to bacteremia, and other manifestations such as meningitis, with a mortality rate close to 30% even with antibiotic treatment.
  • Pneumococcus is encapsulated with a chemically linked polysaccharide which confers serotype specificity.
  • a chemically linked polysaccharide which confers serotype specificity.
  • the capsule is the principle virulence determinant for pneumococci, as the capsule not only protects the inner surface of the bacteria from complement, but is itself poorly immunogenic.
  • Polysaccharides are T-independent antigens, and can not be processed or presented on MHC molecules to interact with T-cells. They can however, stimulate the immune system through an alternate mechanism which involves cross-linking of surface receptors on B cells.
  • Polysaccharide antigen based vaccines are well known in the art. Four that have been licensed for human use include the Vi polysaccharide of Salmonella typhi , the PRP polysaccharide from Haemophilus influenzae , the tetravalent meningococcal vaccine composed of serotypes A, C, W135 and Y, and the 23-Valent pneumococcal vaccine composed of the polysaccharides corresponding to serotypes 1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19A, 19F, 20, 22F, 23F, and 33 (accounting for at least 90% of pneumococcal blood isolates).
  • the 23-valent unconjugated pneumococcal vaccine has shown a wide variation in clinical efficacy, from 0% to 81% (Fedson et al. (1994) Arch Intern Med. 154: 2531-2535). The efficacy appears to be related to the risk group that is being immunised, such as the elderly, Hodgkin's disease, splenectomy, sickle cell disease and agammaglobulinemics (Fine et al. (1994) Arch Intern Med. 154:2666-2677), and also to the disease manifestation.
  • the 23-valent vaccine does not demonstrate protection against pneumococcal pneumonia (in certain high risk groups such as the elderly) and otitis media diseases.
  • the present invention provides such an improved vaccine.
  • Aluminium-based adjuvants are examples of the carrier class of adjuvant which works through the “depot effect” it induces. Antigen is adsorbed onto its surface and when the composition is injected the adjuvant and antigen do not immediately dissipate in the blood stream—instead the composition persists in the local environment of the injection and a more pronounced immune response results.
  • carrier adjuvants have the additional known advantage of being suitable for stabilising antigens that are prone to breakdown, for instance some polysaccharide antigens.
  • 3D-MPL is an example of a non-carrier adjuvant. Its full name is 3-O-deacylated monophosphoryl lipid A (or 3 De-O-acylated monophosphoryl lipid A or 3-O-desacyl-4′ monophosphoryl lipid A) and is referred to as 3D-MPL to indicate that position 3 of the reducing end glucosamine is de-O-acylated. For its preparation, see GB 2220211 A. Chemically it is a mixture of 3-deacylated monophosphoryl lipid A with 4, 5 or 6 acylated chains. It was originally made in the early 1990's when the method to 3-O-deacylate the 4′-monophosphoryl derivative of lipid A (MPL) led to a molecule with further attenuated toxicity with no change in the immunostimulating activity.
  • MPL 4′-monophosphoryl derivative of lipid A
  • 3D-MPL has been used as an adjuvant either on its own or, preferentially, combined with a depot-type carrier adjuvant such as aluminium hydroxide, aluminium phosphate or oil-in-water emulsions.
  • a depot-type carrier adjuvant such as aluminium hydroxide, aluminium phosphate or oil-in-water emulsions.
  • antigen and 3D-MPL are contained in the same particulate structures, allowing for more efficient delivery of antigenic and immunostimulatory signals.
  • Studies have shown that 3D-MPL is able to further enhance the immunogenicity of an alum-adsorbed antigen [Thoelen et al. Vaccine (1998) 16:708-14; EP 689454-B1].
  • Such combinations are also preferred in the art for antigens that are prone to adsorption (for instance, bacterial polysaccharide conjugates), where adsorption onto alum tends to stabilise the antigen.
  • Precipitated aluminium-based adjuvants are mostly used as they are the only adjuvants that are currently used in licensed human vaccines. Accordingly, vaccines containing 3D-MPL in combination with aluminium-based adjuvants are favoured in the art due to their ease of development and speed of introduction onto the market.
  • MPL non 3-deacylated
  • MPL has been evaluated as an adjuvant with several monovalent polysaccharide-conjugate vaccine antigens.
  • Coinjection of MPL in saline enhanced the serum antibody response for four monovalent polysaccharide conjugates: pneumococcal PS 6B-tetanus toxoid, pneumococcal PS 12-diphtheria toxoid, and S. aureus type 5 and S. aureus type 8 conjugated to Pseudomonas aeruginosa exotoxin A [Schneerson et al. J. Immunology (1991) 147:2136-2140]. The enhanced responses were taught as being antigen-specific.
  • MPL in an oil-in-water emulsion consistently enhanced the effect of MPL in saline due to the presence of MPL and antigen in the same particulate structure, and was considered to be the adjuvant system of choice for optimal delivery of other polysaccharide conjugate vaccines.
  • Devi et al. [Infect. Immun. (1991) 59:3700-7] evaluated the adjuvant effect of MPL (non 3-deacylated) in saline on the murine antibody response to a TT conjugate of Cryptococcus neoformans capsular polysaccharide.
  • MPL non 3-deacylated
  • TT conjugate of Cryptococcus neoformans capsular polysaccharide.
  • the adjuvant effect of MPL with polysaccharides and polysaccharide-protein conjugates appears to be composition-dependent. Again, the incorporation of MPL in a suitable slow-release delivery systems (for instance using a carrier adjuvant) provides a more durable adjuvant effect and circumvents the problem of timing and delayed administration.
  • the present inventors have found that for certain pneumococcal polysaccharide conjugates, the immunogenicity of the vaccine composition is significantly greater when the antigen is formulated with 3D-MPL alone rather than with 3D-MPL in conjunction with a carrier adjuvant (such as an aluminium-based adjuvant). Furthermore the observed improvement is independent of the concentration of 3D-MPL used, and whether the particular conjugates are in a monovalent composition or whether they are combined to form a polyvalent composition.
  • polysaccharide antigen based vaccines are well known in the art.
  • the licensed polysaccharide vaccines mentioned above have different demonstrated clinical efficacy.
  • the Vi polysaccharide vaccine has been estimated to have an efficacy between 55% and 77% in preventing culture confirmed typhoid fever (Plotkin and Cam, (1995) Arch Intern Med 155: 2293-99).
  • the meningococcal C polysaccharide vaccine was shown to have an efficacy of 79% under epidemic conditions (De Wals P, et al. (1996) Bull World Health Organ. 74: 407-411).
  • the 23-valent pneumococcal vaccine has shown a wide variation in clinical efficacy, from 0% to 81% (Fedson et al. (1994) Arch Intern Med. 154: 2531-2535) As mentioned above, it is accepted that the protective efficacy of the pneumococcal vaccine is more or less related to the concentration of antibody induced upon vaccination.
  • Examples of these highly immunogenic carriers which are currently commonly used for the production of polysaccharide immunogens include the Diphtheria toxoid (DT or the CRM197 mutant), Tetanus toxoid (TT), Keyhole Limpet Haemocyanin (KLH), and the purified protein derivative of Tuberculin (PPD).
  • KLH is known as potent immunogen and has already been used as a carrier for IgE peptides in human clinical trials. However, some adverse reactions (DTH-like reactions or IgE sensitisation) as well as antibody responses against antibody have been observed.
  • the present invention provides a new carrier for use in the preparation of polysaccharide/polypeptide-based immunogenic conjugates, that does not suffer from the aforementioned disadvantages.
  • the present invention provides a protein D (EP 0 594 610 B1) from Haemophilus influenzae, or fragments thereof, as a carrier for polysaccharide based immunogenic compositions, including vaccines.
  • a protein D EP 0 594 610 B1
  • This carrier is particularly advantageous in combination vaccines.
  • the present invention provides a vaccine composition, comprising at least one Streptococcus pneumoniae polysaccharide antigen (preferably conjugated) and a Streptococcus pneumoniae protein antigen or immunologically functional equivalent thereof, optionally with a Th1 adjuvant (an adjuvant inducing a Th1 immune response).
  • a Th1 adjuvant an adjuvant inducing a Th1 immune response.
  • both a pneumococcal protein and Th1 adjuvant are included.
  • the compositions of the invention are particularly suited in the treatment of elderly pneumonia.
  • Pneumococcal polysaccharide vaccines may not be able to protect against pneumonia in the elderly population for which the incidence of this disease is very high.
  • the key defense mechanism against the pneumococcus is opsonophagocytosis (a humoral B-cell/neutrophil mediated event caused by the production of antibodies against the pneumococcal polysaccharide, the bacterium eventually becoming phagocytosed), however parts of the involved opsonic mechanisms are impaired in the elderly, i.e. superoxide production by PMN (polymorphonuclear cells), other reactive oxygen species production, mobilization of PMN, apoptosis of PMN, deformability of PMN.
  • Antibody responses may also be impaired in the elderly.
  • the present inventors have found that by simultaneously stimulating the cell mediated branch of the immune system (for instance T-cell meditated immunity) in addition to the humoral brach of the immune system (B-cell mediated), a synergy (or cooperation) results which is capable of enhancing the clearance of pneumococci from the host.
  • T-cell meditated immunity for instance T-cell meditated immunity
  • B-cell mediated humoral brach of the immune system
  • both arms of the immune system may synergise in this way if a pneumococcal polysaccharide (preferably conjugated) is administered with a pneumococcal protein (preferably a protein expressed on the surface of pneumococci, or secreted or released, which can be processed and presented in the context of Class II and MHC class I on the surface of infected mammalian cells).
  • a pneumococcal protein can trigger cell mediated immunity by itself
  • the inventors have also found that the presence of a Th1 inducing adjuvant in the vaccine formulation helps this arm of the immune system, and surprisingly further enhances the synergy between both arms of the immune system.
  • the present invention also provides an antigenic composition comprising one or more pneumococcal polysaccharide conjugates adjuvanted with 3D-MPL and substantially devoid of aluminium-based adjuvants, wherein at least one of the pneumococcal polysaccharide conjugates is significantly more immunogenic in compositions comprising 3D-MPL in comparison with compositions comprising 3D-MPL in conjunction with an aluminium-based adjuvant.
  • compositions comprising conjugates of one or more of the following pneumococcal capsular polysaccharides: serotype 4, 6B, 18C, 19F, and 23F.

  • the present invention provides a combination antigenic composition substantially devoid of aluminium-based adjuvants and comprising 3D-MPL adjuvant and two or more pneumococcal polysaccharide conjugates chosen from the group consisting of: serotype 4; serotype 6B; serotype 18C; serotype 19F; and serotype 23F.
  • the present invention provides a polysaccharide conjugate antigen comprising a polysaccharide antigen derived from a pathogenic bacterium conjugated to protein D from Haemophilus influenzae or a protein D fragment thereof.
  • the invention provides polyvalent vaccine compositions where one or more of the polysaccharide antigens are conjugated to protein D.
  • the present invention provides an improved vaccine particularly for the prevention or amelioration of pnemococcal infection of the elderly (and/or infants and toddlers).
