Summary for Patent: 5,780,029

Title:	Antidiotypic monoclonal antibodies for treatment of melanoma
Abstract:	The invention concerns murine antiidiotypic monoclonal antibodies which are the internal image of determinants recognized by a monoclonal antibody on high molecular weight-melanoma associated antigen (HMW-MAA), antibody derivatives, hybridoma cell lines secreting such antiidiotypic monoclonal antibodies, and processes for the preparation of such antiidiotypic monoclonal antibodies, of their derivatives and of the hybridoma cell lines. The murine antiidiotypic monoclonal antibodies are useful for the determination of antibodies directed against high molecular weight-melanoma associated antigen, for the modulation of the immune response to HMW-MAA and for the treatment of melanoma.
Inventor(s):	Ferrone; Soldano (Scarsdale, NY)
Assignee:	New York Medical College (Valhalla, NY)
Application Number:	08/549,423
Patent Claims:	1. A pharmaceutical composition for the treatment of melanoma comprising a murine antiidiotypic monoclonal antibody designated Mab MK2-23 which is produced by the hybridoma cell line deposited with the American Type Culture Collection (ATCC) under accession No. HB 10288 or a conjugate or fragment thereof retaining the specificity of antibody MK2-23 and a pharmaceutically acceptable carrier. 2. A pharmaceutical composition according to claim 1 wherein antibody MK2-23, or a fragment thereof that retains the specificity of antibody MK2-23, is conjugated with a carrier which enhances immunogenicity thereof. 3. A pharmaceutical composition according to claim 2 wherein the carrier is keyhole limpet haemocyanin (KLH). 4. A pharmaceutical composition according to claim 3 further comprising the adjuvant Bacillus Calmette-Guerin (BCG). 5. A method of treating a warm-blooded animal including man in need of treatment of melanoma which comprises administering to said animal a therapeutically effective amount of a murine antiidiotypic monoclonal antibody designated Mab MK2-23 which is produced by the hybridoma cell line deposited with the American Type Culture Collection (ATCC) under accession No. HB 10288 or a conjugate or fragment thereof retaining the specificity of antibody MK2-23. 6. A method of treating a warm-blooded animal including man in need of treatment of melanoma which comprises administering to said animal a therapeutically effective amount of a conjugate or fragment of a murine antiidiotypic monoclonal antibody designated Mab MK2-23 which is produced by the hybridoma cell line deposited with the American Type Culture Collection (ATCC) under accession No. HB 10288 which conjugate or fragment retains the specificity of antibody MK2-23.
