Abstract: The present invention discloses inhibitory antibodies against Factor VIII with modified glycosylation, either by enzymatic deglycosylation or by site directed mutagenesis. Said antibodies with modified glycosylation have equal affinity for FVIII but show different inhibiting properties. The use of one or a mixture of said antibodies allow modulation of the inhibition of factor VIII to levels between 40 and 95%. The present invention further discloses pharmaceutical compositions comprising inhibitory antibodies against Factor VIII with modified glycosylation, combinations of these antibodies and methods for treating haemostasis disorders using said antibodies and antibody mixtures.

Abstract: The present invention is related to a monoclonal anti-idiotypic antibody directed against a Factor VIII inhibitor antibody binding to the C1 domain of Factor VIII, as well as to a cell line producing this monoclonal anti-idiotypic antibody, to the use of this monoclonal anti-idiotypic antibody as medicament, and more particularly to the use thereof for manufacturing a medicament intended for the treatment of haemophilia A.

Abstract: The present invention is related to a method for modulating the immune system of a mammal patient towards an allergen, which comprises the step of inducing a pre-sensitisation of the immune system of said patient towards an immunogen carrying at least one T cell epitope homologous and functionally similar to an epitope present on said allergen and deriving from a naturally-occurring antigen in order to modify the response of said patient to a further sensitisation to said allergen, allowing that the immune response towards the allergen is modulated and that no allergy towards said allergen will be developed in said patient.

Abstract: The present invention relates to new antibodies and fragments and derivatives thereof, which are particularly suited for the characterization of the structure and function of Factor VIII (FVIII) of the coagulation pathway, for the design of therapeutic strategies for eradication of FVIII inhibitors and for the use as a medicament The invention also relates to cell lines producing the specific antibodies. The present invention furthermore relates to pharmaceutical compositions comprising the antibodies, fragments and/or derivatives of the Invention and to methods of preventing and treating cardiovascular disorders by using the antibodies or fragments and derivatives thereof or pharmaceutical compositions thereof.

Abstract: The present invention discloses anti-idiotypic antibodies and fragments thereof against inhibitory Factor VIII anti-bodies, said inhibitory antibodies having an affinity for the C2 domain of Factor VIII. The anti-idiotypic antibodies of the present invention are able to completely neutralise in vitro and in an in vivo mouse model the inhibitory activity of FVIII inhibitors. The anti idiotypic antibodies of the present invention can be applied for the prevention, treatment or reduction of bleeding disorders of hemophilia patients with inhibitory antibody against the C2 domain of Factor VIII.

Abstract: The invention, in general, features a method of treatment and/or prevention of a thrombotic pathological condition, in a mammal, which includes administering to the mammal in need of such treatment a therapeutically effective amount of a composition including an antibody directed against the C1 domain of Factor VIII, which is a partially inhibitory antibody of Factor VIII.

Abstract: The present invention is related to a compound for the prevention and/or the treatment of allergy consisting of:

Abstract: The present invention is related to a compound for the prevention and/or the treatment of allergy consisting of: at least one allergen antigenic determinant which is recognized by a B cell or an antibody secreted by a B cell of a non-atopic individual to said allergen, and at least one antigenic determinant of an antigen different from said allergen which triggers T cell activation.

Abstract: A pharmaceutical composition suitable for administration to human beings for suppressing the production of factor VIII inhibitor includes:an immune complex of factor VIII antigen component and factor VIII inhibitor component, the components being present in a ratio such that the inhibitor blocks essentially all relevant binding sites of the antigen; anda pharmacologically acceptable carrier or diluent. The invention also provides a method of administering the compositions to suppress the production of inhibitor to factor VIII.

Abstract: A pharmaceutical composition comprises an immune complex of an allergen and a purified antibody specific thereto, the allergen being selected from a specific subclass of antigen which causes immediate hypersensitivity that is mediated by IgE antibody, and a pharmacologically acceptable carrier or diluent. The method of using the compositions in the treatment of immediate hypersensitivity to the allergen is also described.
