"The interim analysis of our Phase 3 IMPACT trial was an important milestone for us. We were encouraged to see a 20 percent reduction in the risk of death in the PROVENGE arm versus placebo at the time of this analysis in a patient population that currently has few appealing treatment options available," stated Mitchell H.
