Study Endpoints
Primary Endpoints
Kaplan-Meier Estimates for Time to Death (Overall Survival)
Randomization (approximately Day -12) to longest survival follow-up (Day 971).

Time from the date of randomization to death from any cause. After stopping treatment, patients were followed every 4 weeks until disease progression and then followed every 12 weeks until death.

Safety and Tolerability of Custirsen (OGX-011) in Combination With Either Docetaxel/Prednisone or Mitoxantrone/Prednisone as Second-line Chemotherapy.
Subjects were followed for safety from enrollment for up to 8 months (9 three-week cycles plus 30 days after end of treatment)

Safety and tolerability were based on Adverse Events (AE) and Serious Adverse Events (SAE) graded using National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE). The CTCAE has 5 grades with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1=Mild AE; Grade 2=Moderate AE; Grade 3=Severe AE; Grade 4=Life-threatening or disabling AE; and Grade 5=Death related to AE.

Secondary Endpoints
Percentage of Participants Who Were Alive Without Event At Day 140
Day 125-155
Percentage of Participants with Adverse Events
Docetaxel/prednisone/custirsen arm: Days -9 up to Day 743. Docetaxel/prednisone arm: Day 1 up to Day 400.
Feasibility of Treatment With Custirsen (OGX-011) in Combination With Second-line Chemotherapy Based on Prostate Specific Antigen (PSA) Response
PSA was evaluated at screening, on Day 1 of each cycle, at the end of treatment visit and during off-treatment follow up (up to 27 months)

Custirsen, Docetaxel, PrednisoneEXPERIMENTALThree doses of 640 mg custirsen administered intravenously (IV) as a loading dose between Days -9 to -1. Custirsen, 640 mg, given IV weekly on Days 1, 8, and 15 of each 21-day cycle. Docetaxel (75 mg/M\^2 via intravenous injection) on Day 1 of every 21 days plus prednisone (5 mg tablets taken by mouth) twice each day and dexamethasone (8 mg by mouth twice a day for 3 days beginning one day before docetaxel administration). Treatment continues for 10 cycles or until unacceptable toxicity or disease progression.

DexamethasoneDRUGDexamethasone 8 mg by mouth twice a day for 3 days beginning one day before docetaxel administration to reduce the incidence and severity of hypersensitivity reactions and fluid retention.
custirsen (OGX-011)/mitoxantroneDRUGAll 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.
