Exhibit 99.1
Dendreon Announces FDA Advisory Committee Reviewed Provenge® for
Hormone Refractory Prostate Cancer
—Committee Recognizes Substantial Evidence of Efficacy and Safety in this Patient Population—
—New time for conference call at 6:30 PM ET—
SEATTLE, WA,March 29, 2007 — Dendreon Corporation (Nasdaq: DNDN) today announced that the U.S. Food and Drug Administration’s (FDA) Office of Cellular, Tissue and Gene Therapies Advisory Committee recommended to the FDA that there is substantial evidence of efficacy and safety of PROVENGE (sipuleucel-T) for the treatment of patients with asymptomatic, metastatic, androgen-independent (also known as hormone refractory) prostate cancer. If approved for marketing by the FDA, PROVENGE would become the first active cellular immunotherapy and the first biologic approved to treat prostate cancer. The FDA will now review the advisory committee’s recommendations. The Company anticipates a decision on PROVENGE by May 15, 2007.
The Advisory Committee was asked if the submitted data established that sipuleucel-T (APC-8015) is reasonably safe and whether there is substantial evidence that the product is efficacious.
The Advisory Committee voted 17 to 0 in favor of the safety of PROVENGE in response to the question and 13 to 4 in favor of the efficacy question.
“Today marks an important milestone for men with advanced prostate cancer,” said Mitchell H. Gold, M.D., president and chief executive officer of Dendreon. “If approved, PROVENGE could become a breakthrough treatment for patients with advanced prostate cancer who currently have few treatment options. We look forward to working closely with the FDA.”
Prostate cancer is the most common non-skin cancer in the United States and the third most common cancer worldwide. More than one million men in the United States have prostate cancer, with an estimated 218,890 new cases of prostate cancer diagnosed each year. More than 27,000 men die each year of the disease.

Except for historical information contained herein, this news release contains forward-looking statements that are subject to risks and uncertainties surrounding the efficacy of PROVENGE to treat men suffering from prostate cancer, risks and uncertainties surrounding the presentation of data to the FDA and approval of product applications by the FDA and risks and uncertainties inherent in the process of discovering, developing and commercializing drugs that are safe and effective for use as human therapeutics. Factors that may cause such differences include risks related to our limited operating history, risks associated with completing our clinical trials, the risk that the safety and/or efficacy results of a clinical trial for PROVENGE will not support an application for a biologics license, the risk that the FDA may interpret data differently than we do or require more data or a more rigorous analysis of data than expected, the risk that the FDA will not approve a product for which a biologics license has been applied, the risk that the results of a clinical trial for PROVENGE or other product may not be indicative of results obtained in a later clinical trial, risks that we may lack the financial resources and access to capital to fund required clinical trials or commercialization of PROVENGE, our dependence on the efforts of third parties, and our dependence on intellectual property.
