A site to advocate for “Provenge Now!” has been launched. Provenge is Dendreon’s immunotherapy for prostate cancer, which was approved 17-0 for safety and 13-4 for efficacy by an FDA Advisory Committee vote March 29th this year. On May 9, Dendreon announced that FDA has sent them a “Complete Response Letter,” commonly called an approvable letter, requesting more data. Dendreon CEO Mitchell Gold said “The FDA has requested additional clinical data in support of the efficacy claim.”
