Phase II, Randomized, Open-Label, Two-Arm, Multicenter Study of MEDI-522, a HuMA Directed Against the Human Alpha V Beta 3 Integrin, in Combination With Docetaxel, Prednisone, and Zoledronic Acid in the Treatment of Patients With Metastatic Androgen-Independent Prostate Cancer

The primary objectives of this study are: 1. To explore the antitumor activity of MEDI-522 in combination with docetaxel, prednisone, and zoledronic acid in patients with metastatic Androgen-Independent Prostate Cancer (AIPC); and 2. To summarize the safety of MEDI-522 in combination with docetaxel, prednisone, and zoledronic acid in this patient population.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.

Phase: Phase 2


Ages Eligible For Study:

18 Years - N/A

Inclusion Criteria

- Adult men at least 18 years of age at the time of randomization. - Metastatic, histologically or cytologically confirmed adenocarcinoma of the prostate that has progressed after start of androgen deprivation therapy, which includes prior orchiectomy or medical castration using leuteinizing hormone-releasing hormone (LHRH) antagonists such as leuprolide or goserelin (patients must remain on LHRH analogue therapy for the duration of the study if not surgically castrated). Progressive disease should be documented by: a. PSA progression (defined as two consecutive increases in PSA over a previous reference value, with the first increase in PSA occurring at a minimum of 1 week after the reference value [obtained within 2 months prior to study randomization] and confirmed by a subsequent increase in PSA whose value must be 5 ng/mL prior to study randomization);41 and one of the following: i. Bone metastases (defined as 3 foci on bone scan and confirmed radiologically within 1 month prior to study randomization); or ii. Measurable non-bony metastatic disease (documented by radiographic studies performed within 1 month prior to study randomization). - Serum testosterone levels <50 ng/dL documented in non-surgically castrated patients within 21 days prior to randomization. - Prior treatment with nonsteroidal antiandrogens (e.g., flutamide or bicalutamide) is allowed provided: - There is evidence of disease progression (defined in Inclusion Criteria #2) following withdrawal of antiandrogens; and b. At least 4 weeks for flutamide or 6 weeks for bicalutamide have passed since last treatment. - Prior treatment with ketoconazole and/or steroids is allowed provided at least 4 weeks have passed since last treatment. There are no restrictions for use of prednisone (5 mg twice daily) or another functionally equivalent oral corticosteroid for treatment of pain. - In the rare instance a patient is potent, he must agree to practice an effective method of contraception including condom or abstinence, unless his sexual partner is sterile, from the time of first administration of MEDI-522 or docetaxel through 30 days after the last dose of either docetaxel or MEDI-522, whichever is the last drug discontinued. - Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2 documented within 21 days prior to randomization. - Life expectancy, in the opinion of the investigator, of at least 6 months. - White blood cell (WBC) count ? 3,000/mm3; absolute neutrophil count (ANC) ? 1,500/mm3; platelet count ? 100,000/mm3; and hemoglobin 9 g/dL documented within 21 days prior to randomization. - Bilirubin ? ULN; aspartate transaminase (AST)/alanine transaminase (ALT) 1.5 times ULN or if AST/ALT is >1.5 times ULN, then alkaline phosphatase must be 2.5 times ULN; serum creatinine ? 1.5 mg/dL; INR within normal range, unless a patient is receiving anticoagulation therapy; and corrected serum calcium between 8.0-11.5 mg/dL documented within 21 days prior to randomization. - Patients who had prior major surgery are eligible if at least 4 weeks have passed since their surgery and all surgical wounds have healed prior to study randomization. - Prior radiotherapy including therapeutic isotopes is allowed provided measurable or evaluable disease that is clearly progressing is present and all acute radiation-related toxicities have resolved prior to study randomization. - Prior treatment with unconventional therapy for malignancy (e.g., vitamins, St. John's Wort, PC-SPES, saw palmetto, or other herbal remedies) is allowed provided at least 4 weeks have passed since last treatment prior to randomization. - Written informed consent and HIPAA authorization (USA sites only) obtained from the patient prior to receipt of any study medication or beginning study procedures.
