Abstract:
Peptides having at least nine amino acid residues each including an amino acid sequence which corresponds to position p200-208 or p262-266 of the human acetylcholine receptor α-subunit, but differing therefrom by one or more amino acid substitutions, are disclosed. These peptides inhibit the proliferative response of human peripheral blood lymphocytes to the myasthogenic peptides p195-212 and p259-271 and are suitable for treatment of subjects afflicted with myasthenia gravis.
Abstract:
Compositions and methods for treating and preventing host-versus-graft disease and graft-versus-host disease comprising as active ingredient random copolymers of amino acids comprising one amino acid from at least three of the following groups: (a) lysine and arginine; (b) glutamic acid and aspartic acid; (c) alanine and glycine; and (d) tyrosine and tryptophan; with the proviso that the random copolymer is not Copolymer 1 or D-Copolymer 1 when the disease being treated is graft-versus-host disease.

Abstract:
Procédé de détermination de l'efficacité d'un agent thérapeutique, in vitro, utilisé dans le traitement d'un cancer caractérisé par l'expression ou la surexpression d'un produit oncogène. Le procédé est notamment utile pour déterminer l'efficacité d'agents thérapeutiques présentant une affinité de liaison pour le cancer, exprimant HER-2/neu. L'invention concerne également les anticorps monoclonaux N24, N28 et N29 identifiés par ce procédé. On peut utiliser un ou plusieurs de ces anticorps comme agent thérapeutique dans le traitement des cancers du sein, de l'estomac, des ovaires ou des glandes salivaires.
Abstract:
A method for determining the efficacy of a therapeutic agent, in vitro, for a cancer expressing or overexpressing an oncogene product is described. The method is particularly useful for determining the efficacy of therapeutic agents that have a binding affinity for cancer that express HER-2/neu. N24, N28 and N29 monoclonal antibodies are described which have been identified by this method. One or more of these antibodies can be used as a therapeutic agent in the treatment of breast, stomach, ovarian or salivary cancers.
Abstract:
A method of identifying a combination of antibodies with a combined improved anti-tumor activity is provided. The method comprising: (a) identifying binding epitopes of anti ErbB-2 antibodies; and (b) selecting a combination of at least two antibodies of the anti ErbB-2 antibodies exhibiting binding to different epitopes on the ErbB-2, at least one of the different epitopes being localized to a dimerization site of the ErbB-2, the combination of antibodies being with the combined improved anti-tumor activity. Also provided are novel antibody combinations uncovered according to the present teachings.
