Trial Information

Androgen Receptor Mutations in Hormone Refractory Prostate Cancer

OBJECTIVES: I. Test the feasibility of obtaining bone marrow specimens in a cooperative
group setting. II. Determine the frequency of bone marrow invasion by prostate cancer cells
in patients with hormone refractory prostate cancer. III. Evaluate the frequency of androgen
receptor (AR) mutations in bone marrow samples in this patient population. IV. Evaluate the
association between AR mutations and clinical outcomes, including survival, and response to
therapy, such as antiandrogen withdrawal. V. Evaluate the impact of prior pelvic
radiotherapy on the ability to obtain informative tissue.

OUTLINE: Blood and a bone marrow biopsy are collected from each patient before the patient
begins treatment on CLB-9480 or CLB-9583. The specimens are analyzed for androgen receptor
mutations. Patients do not receive results of the genetic testing and the results do not
influence the type or duration of treatment.

PROJECTED ACCRUAL: A total of 243 patients will be accrued for this study.
