Provenge® (Sipuleucel-T) Active Cellular Immunotherapy Treatment of Metastatic Prostate Cancer After Failing Hormone Therapy
Provenge is an investigational product designed to activate a man's own antigen presenting cells, a type of immune cell, so that they can detect prostate cancer cells and initiate an immune response against them.
Having completed Phase 1 and Phase 2 clinical trials, Provenge is now at the Phase 3 level. One important Phase 3 trial of Provenge has been completed; the current trial is also a Phase 3 study.
If you decide to participate and are eligible, you will be enrolled in the study and randomly assigned to receive either active product or placebo. There are two chances in three that you will receive Provenge. After receiving treatment, you will be monitored at regular intervals until the study endpoints are met. At the end of the trial, men who received placebo will have the opportunity to be treated with active product in another study.
|Study Design:||Allocation: Randomized

Primary Purpose: Treatment
|Official Title:||A Randomized, Double Blind, Placebo Controlled Phase 3 Trial of Immunotherapy With Autologous Antigen Presenting Cells Loading With PA2024 (Provenge(R), APC8015) in Men With Metastatic Androgen Independent Prostatic Adenocarcinoma|
- Overall Survival [ Time Frame: Event-driven timeframe. Final analysis at 331 events. ]Time from randomization until death due to any cause.
- Time to Objective Disease Progression [ Time Frame: Analysis conducted at the time of overall survival analysis ]Measured by imaging studies; confirmed by independent imaging review
|Study Start Date:||July 2003|
|Study Completion Date:||January 2009|
|Primary Completion Date:||January 2009 (Final data collection date for primary outcome measure)|
|Placebo Comparator: APC-Placebo||
Each dose of APC-Placebo contains approximately one-third of the quiescent APCs prepared from a single leukapheresis procedure. A course of therapy consists of 3 complete doses given at approximately 2-week intervals.
|Active Comparator: Sipuleucel-T||
Each dose of sipuleucel-T contains a minimum of 50 million autologous CD54+ cells activated with a PAP-GM-CSF. A course of therapy consists of 3 complete doses given at approximately 2-week intervals.
The trial is being conducted at multiple study centers throughout the United States. The trial is a double-blind, placebo-controlled trial. Participants must meet specific eligibility criteria. Study personnel will determine your eligibility in a telephone interview and through routine medical tests (physical exam, blood tests, imaging scans) done at a study center.
If you qualify for and decide to participate in the trial, you will have three product administrations over the course of one month.
