Localized therapy for prostate cancer is often curative; however, 20% to 30% of patients experience a recurrence. Biochemical recurrence (BCR) occurs in an estimated 50,000 men/year in the U.S and is marked by a rising prostate specific antigen (PSA) after definitive radical prostatectomy and/or radiation therapy for localized disease.
Continuous androgen deprivation therapy (ADT), in which serum testosterone is decreased to a castrate level (less than 50 ng/dL) is a standard treatment in BCR. ADT is associated with significant short term and long term toxicities, including declining quality of life on treatment and increased risk of osteoporosis, diabetes, and cardiovascular disease. MBM-02 is being tested as a novel non-hormonal agent with improved biologic activity and better tolerability for use in biochemically recurrent prostate cancer.
