Title: A Pilot Study Evaluating the Safety and Feasibility of Custirsen (OGX-011) in Combination With Second Line Chemotherapy in Patients With Hormone Refractory Prostate Cancer
In Brief
A Phase 2 clinical trial evaluating custirsen (OGX-011)/mitoxantrone and custirsen (OGX-011)/docetaxel for Prostate Cancer. Completed, enrolled 70 participants across 10 sites.
Detailed Summary
This study is for patients with cancer of the prostate gland that has metastasized or spread outside the prostate to other parts of the body. Patients have already been treated with a drug called docetaxel or Taxotere® (with or without the addition of a steroid called prednisone) some time in the recent past. They either did not respond to this therapy or responded to this therapy, but now the cancer is progressing (growing larger or has spread to other areas of the body). Custirsen (OGX-011) is an experimental drug that has been shown to increase the effectiveness of chemotherapy in several kinds of tumors, including prostate cancer. Both docetaxel and mitoxantrone have anticancer activity in prostate and are approved by Health Canada and the Food and Drug Administration for the treatment of patients with prostate cancer.

Interventions
All subjects began treatment with oral prednisone (5 mg twice daily, 10 mg/day) continued through completion of the final treatment cycle. Three IV administrations of OGX-011 (640 mg) were given as 2 hr infusions during the loading dose period (Days-9 to-1). Subjects were premedicated with either ibuprofen (400 mg) or acetaminophen (650 mg) 30 to 60 minutes prior to and every 4-6 hours for 24 hours following each of the three doses of OGX-011 during the loading dose period only. After the loading dose period, OGX-011 was given weekly on Days 1, 8, and 15 of each 21-day cycle. Mitoxantrone was administered IV on Day 1 of each cycle at a planned dose of 12 mg/m² infused over 30 minutes. Patients could receive a maximum of 9 cycles of treatment.
