Dr. Aya Jakobovits, from UroGenesys, Inc. in Santa Monica, California, and colleagues assessed the therapeutic efficacy of two different anti-PSCA antibodies in mice bearing human prostate cancer xenografts.
Both antibodies inhibited subcutaneous and orthotopic xenograft tumors in a dose-dependent fashion, the authors state. In addition, with anti-PSCA therapy, established tumor growth was retarded and distant metastatic disease was inhibited, resulting in significantly prolonged survival.
"Our studies demonstrate a broad antitumor efficacy of anti-PSCA antibodies on initiation and progression of prostate cancer in xenograft mouse models," the researchers conclude. "PSCA is one of the few largely prostate-specific cell-surface antigens that represent potential antibody therapy targets for prostate cancer."
