Dendreon Reports Third Quarter 2008 Financial Results

SEATTLE, Nov. 7 /PRNewswire-FirstCall/ -- Dendreon Corporation today reported results for the quarter ended September 30, 2008. Revenue for the third quarter of 2008 was $26,000 compared to $112,000 for the quarter ended September 30, 2007. Revenue for the nine months ended September 30, 2008 was $83,000 compared to $715,000 for the nine months ended September 30, 2007.

Dendreon's total operating expenses for the third quarter of 2008 were $17.3 million compared to $19.8 million in 2007. Dendreon's total operating expenses for the nine months ended September 30, 2008 were $55.1 million compared to $75.2 million for the same period in 2007.

The net loss for the quarter ended September 30, 2008 was $26.8 million, or $0.29 per share, compared to a net loss of $19.2 million, or $0.23 per share, for the quarter ended September 30, 2007. The net loss for the nine months ended September 30, 2008 was $62.8 million, or $0.71 per share, compared to $72.3 million, or $0.88 per share for the nine months ended September 30, 2007. Included in our net loss for the three and nine months ended September 30, 2008 was a non-cash charge of $9.1 million and $6.8 million, respectively, to other expense. This represents an increase in the fair value of the warrants issued in connection with our April 3, 2008 common stock offering, which has been recorded as a liability.

Cash, cash equivalents and short-term and long-term investments at September 30, 2008 totaled $106.6 million compared to $120.6 million at December 31, 2007. Additionally, subsequent to September 30, 2008, the Company received net proceeds of $19.8 million relating to a draw down on the Company's equity line of credit with Azimuth Opportunity Ltd.

   Recent Highlights:    *    Completed the planned interim analysis of the Phase 3, randomized,        double-blind, placebo-controlled IMPACT (IMmunotherapy for Prostate        AdenoCarcinoma Treatment, also known as D9902B) clinical trial        designed to assess the safety and efficacy of the investigational        active cellular immunotherapy PROVENGE(R) (sipuleucel-T) in men with        metastatic androgen-independent prostate cancer.  While Dendreon        remains blinded to the data, the independent data monitoring        committee (IDMC) reported to Dendreon a 20 percent reduction in the        risk of death in the PROVENGE arm relative to placebo (Hazard        Ratio= 0.80; 95% Confidence Interval [0.610-1.051]).  The IDMC        observed no safety concerns and recommended that the study continue        to its final analysis, which is expected to be completed in mid-2009.   *    Presented preclinical data on the Company's lead small molecule        candidate, D-3263, which targets Trp-p8 (a transmembrane cation        channel protein also known as Trp-M8), supporting Trp-p8 as a        therapeutic cancer target. Dendreon plans to file an Investigational        New Drug (IND) application later this year with the U.S. Food and        Drug Administration (FDA) to evaluate D-3263 in a Phase 1 dose        escalation study in cancer.   *    Initiated a Phase 2 trial of PROVENGE called ProACT (PROstate Active        Cellular Therapy) or P07-2.  The multicenter trial is enrolling 120        patients with metastatic, androgen independent prostate cancer.   *    Initiated a Phase 2 trial of PROVENGE in men with localized prostate        cancer who are scheduled to undergo a radical prostatectomy.  The        single-center trial called NeoACT (NEOadjuvant Active Cellular        immunoTherapy), or P07-1, which is being conducted at UCSF Helen        Diller Family Comprehensive Cancer Center, is enrolling        approximately 40 patients.   *    In lieu of Dendreon's regularly scheduled quarterly conference call,        the Company will present at two upcoming investor conferences that        will be webcast.  Both conferences will occur later this month and        include:             o    Rodman & Renshaw 10th Annual Healthcare Conference             o    Lazard Capital Markets 5th Annual Healthcare Conference    

"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. Gold, M.D., president and chief executive officer of Dendreon Corporation. "Importantly, the results from this interim analysis are consistent with those from our previous Phase 3 studies at a similar follow-up time, and we are looking forward to the final analysis of the IMPACT trial in the middle of next year."

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 existing clinical trials or from additional clinical trials for PROVENGE will not support approval 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. Further information on the factors and risks that could affect Dendreon's business, financial condition and results of operations are contained in Dendreon's public disclosure filings with the U.S. Securities and Exchange Commission, which are available at
