The results of the Phase 3 study shows that Provenge, made by Dendreon (DNDN) may be the next big thing in the search of prostate cancer treatment. The study results are out today and they show that Provenge significantly prolongs survival in men with advanced prostate cancer.

This was a good news not only for the men with advanced prostate cancer and the researchers, but also the investors of Dendreon as the DNDN stock jumped 150 percent up in the morning trade.

Dendreon researchers and the company say that this study results show statistically significant improvement in overall survival of men with advanced prostate cancer. Provenge is the first active immunotherapy treatment for cancer to prolong survival. Detailed results from the IMPACT study will be presented during a plenary session at the American Urological Association's Annual Meeting in Chicago on Tues., Apr. 28 at 2:20 pm CT.

Dendreon Corporation (Nasdaq: DNDN) announced today that the pivotal Phase 3 IMPACT study of PROVENGE® (sipuleucel-T) in men with advanced prostate cancer met its primary endpoint of improving overall survival compared to a placebo control. The magnitude of the survival difference observed in the intent to treat population resulted in the study successfully achieving the pre-specified level of statistical significance defined by the study's design. The safety profile of PROVENGE appeared to be consistent with prior trials.

The 512-patient, multi-center, randomized, double-blind, placebo-controlled IMPACT (IMmunotherapy for Prostate AdenoCarcinoma Treatment) study enrolled men with metastatic androgen-independent prostate cancer was conducted under a Special Protocol Assessment agreement with the U.S. Food and Drug Administration (FDA).

PROVENGE is Dendreon's investigational product candidate for men with advanced prostate cancer and may represent the first in a new class of active cellular immunotherapies specifically designed to engage the patient's own immune system against cancer.

"Survival is the gold standard outcome for oncology clinical trials, and overall survival was the primary endpoint of the IMPACT trial. The positive results from this landmark study provide confirmatory evidence demonstrating that treatment with PROVENGE may prolong survival," said Mitchell H. Gold, M.D., president and chief executive officer of Dendreon. "We are immensely grateful to our clinical investigators and the more than 1,000 men with advanced prostate cancer who have participated in our studies over the last decade and whose courage and contribution have significantly advanced the understanding and treatment of prostate cancer and the potential role of cancer immunotherapies."

"The successful outcome from the Phase 3 IMPACT study provides validation of the long-pursued goal of harnessing the human immune system against a patient's own cancer," continued Dr. Gold.
