Abstract: A method of treating chronic hepatitis B is disclosed that comprises administering a T cell-stimulating amount of a vaccine to a patient. The vaccine comprises an immunogenic amount of chimeric, carboxy-terminal truncated hepatitis B virus nucleocapsid (core) protein (HBc) that is engineered for both enhanced stability of self-assembled particles and the substantial absence of nucleic acid binding by those particles. The chimeric protein molecule can include one or more immunogenic epitopes peptide-bonded to one or more of the N-terminus, the immunogenic loop or the C-terminus of HBc. The enhanced stability of self-assembled particles is obtained by the presence of at least one heterologous cysteine residue near one or both of the amino-terminus and carboxy-terminus of the chimer molecule.

Abstract: The present invention relates to the provision of novel medicaments for the treatment, prevention or amelioration of allergic disease. In particular, the novel medicaments are isolated peptides incorporating epitopes or mimotopes of surface exposed regions of the C?2 domain of IgE. The inventors have found that these novel regions may be the target for both passive and active immunoprophylaxis or immunotherapy. The invention further relates to methods for production of the medicaments, pharmaceutical compositions containing them and their use in medicine. Also forming an aspect of the present invention are ligands, especially monoclonal antibodies, which are capable of binding the surface exposed IgE regions of the present invention, and their use in medicine as passive immunotherapy or in immunoprophylaxis.

Abstract: Aminopiperidine derivatives and pharmaceutically acceptable derivatives thereof are disclosed. Such derivatives are useful in methods of treatment of bacterial infections in mammals, particularly in man.

Abstract: The present invention relates to the provision of novel medicaments for the treatment, prevention or amelioration of allergic disease. In particular, the novel medicaments are epitopes or mimotopes derived from the C?3 or C?4 domains of IgE. These novel regions may be the target for both passive and active immunoprophylaxis or immunotherapy. The invention further relates to methods for production of the medicaments, pharmaceutical compositions containing them and their use in medicine. Also forming an aspect of the present invention are ligands, especially monoclonal antibodies, which are capable of binding the IgE regions of the present invention, and their use in medicine as passive immunotherapy or immunoprophylaxis.

Abstract: A novel adjuvant composition comprising a sterol (e.g., cholesterol, ?-sitosterol, stigmasterol, ergosterol, and ergocalciferol) and saponin fraction (e.g., QS21, also known as QA21) in the form of an immunostimulating complex, or ISCOM, is disclosed. QS21 is an immunologically active saponin fraction having adjuvant activity derived from the bark of Quillaja Saponaria Molina. Previous attempts in the prior art to prepare ISCOMs comprising QS21 were unsuccessful. Thus, the instant application discloses the first successful attempt to prepare ISCOMs comprising purified QS21. Small unilamelar liposomes containing cholesterol, in the absence of any detergent, were prepared, followed by the addition of an aqueous solution of QS21. The claimed compositions will prove useful in the preparation of highly immunogenic vaccine compositions.

Abstract: The present invention relates to a novel chemical process for the covalent conjugation of disulphide bridge cyclised peptides to immunogenic carrier molecules by thio-ether linkages to form vaccine immunogens. In particular, the novel chemistry involves reacting a thiolated carrier with a cyclic peptide containing a disulphide bridge, which cylcic peptide (herein a disulphide bridge cyclised peptide) has attached to it, usually via a linker, a reactive group capable for forming thio-ether bonds with the carrier. The invention further related to activated peptide intermediates of the process, medicaments produced by the process, pharmaceutical compositions containing the medicaments, and the use of the pharmaceutical compositions in medicine. The process of the present invention is particularly useful for the preparation of highly pure immunogens for vaccines, comprising disulphide bridge cyclised peptides.
