Invention Title: “Monoclonal Antibodies to Prostate Cells”.

Inventor: Dr. Ira H. Pastan (NCI).

USP SN: 5,489,525 [= DHHS Ref. No. E-201-92/0]—Issued on February 6, 1996.


Prostate Cancer is a disease affecting approximately 1 million men in the U.S.A., with an annual incidence of around 179,000 and approximately 30,000 deaths per year. It is estimated that one-third of men over 50 will develop prostate cancer at some time in their lives. Control of primary tumor by surgical resection and/or radiation has proven effective in a number of cases, however, metastatic spread, primarily to the bone, especially at late hormone independent stages of the disease, has been more difficult to control and monitor. With the aging of the U.S. population, it has been estimated that the number of prostate cancer cases will increase dramatically.


The technology disclosed in the 5,489,525 patent relates to a monoclonal antibody which is capable of binding to a cell surface differentiation antigen Start Printed Page 21771specific for prostate adenocarcinomas and other prostate cancer cells. Accordingly, methods of therapy can be employed with this monoclonal antibody to destroy prostate cancer cells, and hence, this monoclonal antibody may be useful in therapy and/or the diagnosis of prostate cancer. This monoclonal antibody can be produced by recombinant DNA techniques, the host cell being a eucaryotic or procaryotic cell, preferably a eucaryotic cell and more preferably mammalian. Hence, a monoclonal antibody, a recombinant monoclonal antibody, single polypeptide binding molecules, and binding fragments thereof coupled to molecules which are cytotoxic to prostate cancer cells (e.g., chemotherapeutic agents, prodrugs, cytotoxic or inhibitory peptides, cytokines, enzymes, diphtheria toxin, Pseudomonas Exotoxin, etc.) could be used to develop a prostate cancer therapeutic or diagnostic test system.

The above mentioned Invention and technology are available for licensing.
