Cell Genesys Reports First Quarter 2007 Results

SOUTH SAN FRANCISCO, Calif., May 10 /PRNewswire-FirstCall/ -- Cell Genesys, Inc. (NASDAQ: CEGE) today reported financial results for the first quarter ended March 31, 2007.

For the first quarter of 2007, the company reported a net loss of $29.4 million, or $0.49 per fully diluted share, compared with net income of $4.0 million, or $0.08 per fully diluted share, for the same period in 2006. The change from net income to net loss in the current quarter is attributed primarily to the absence of gains from sales of marketable securities compared to the first quarter of 2006, at which time the company had a gain of $62.7 million from the sale of 3.0 million shares of common stock of Abgenix, its former subsidiary.

Revenues for the first quarter ended March 31, 2007 were $1.3 million compared with revenues of $0.2 million for the comparable period in 2006. The difference is due to timing of revenue from existing licensing arrangements which varies from quarter to quarter.

The company's research and development costs were $24.0 million for the first quarter of 2007 compared with $25.3 million for the first quarter of 2006. The decrease is primarily due to the timing of expenses related to the ongoing Phase 3 clinical trials of the company's lead product development program, GVAX immunotherapy for prostate cancer. General and administrative expenses were $5.2 million for the first quarter of 2007 compared to $5.0 million for the corresponding period in 2006.

Cell Genesys ended the first quarter of 2007 with approximately $138.6 million in cash, cash equivalents and short-term investments. Following the end of the quarter, the company raised gross proceeds of $60 million in a registered direct offering of common stock and warrants and also reached a favorable settlement with the IRS regarding the audit of the company's 2000 tax return. The settlement with the IRS is for approximately $3.5 million in taxes and interest and results in a decrease in accrued income tax liabilities of approximately $21 million.

"We are pleased with our business progress during the first quarter as well as recent news from our clinical-stage product programs, in particular an encouraging report of the final survival data from our second Phase 2 trial of GVAX immunotherapy for prostate cancer," stated Stephen A. Sherwin, M.D., chairman and chief executive officer of Cell Genesys. "We are also fortunate to continue to have the financial resources we need to move our clinical programs forward, most importantly the ongoing Phase 3 clinical trials for our lead product, GVAX immunotherapy for prostate cancer."

  First Quarter and Other Recent Highlights:

   --   Announced final, updated results from a second multi-center Phase 2
        trial of GVAX immunotherapy for prostate cancer which evaluated
        escalating doses of the immunotherapy in 80 patients with metastatic
        hormone-refractory prostate cancer (HRPC).  Additional follow-up of
        the 22 patients who received the dose that is comparable to that
        being employed in the company's ongoing Phase 3 program indicates
        that the median survival is 35.0 months.  The company previously
        reported final median survival results from its first multi-center
        Phase 2 trial of GVAX immunotherapy for prostate cancer in 34
        patients with metastatic HRPC that showed an overall median survival
        of 26.2 months.  The survival results from the two, independent
        multi-center Phase 2 clinical trials compare favorably to the
        previously published median survival of 18.9 months for metastatic
        hormone-refractory prostate cancer patients treated with Taxotere(R)
        (docetaxel) chemotherapy plus prednisone, the current standard of
        care for these patients.

   --   Reported at the American Society of Clinical Oncology (ASCO)
        Prostate Cancer Symposium in February 2007, encouraging follow-up
        data on the first twelve patients with advanced prostate cancer
        treated on a Phase 1 clinical trial of Cell Genesys' GVAX
        immunotherapy for prostate cancer, administered in combination with
        Medarex's fully human anti-CTLA-4 antibody, ipilimumab (MDX-010).
        The twelve patients who have completed treatment to date include six
        patients who received the combination therapy at doses currently
        being evaluated in both GVAX and ipilimumab Phase 3 clinical trials.
        Antitumor activity has been observed in five of these six patients
        including prostate-specific antigen (PSA) declines of greater than
        50% that were maintained in four of these patients for at least six
        months with the longest response ongoing at more than 12 months.
        Moreover, clinical evidence of antitumor activity has been observed
        in three of these five PSA responders, including improvement of
        multiple lesions on bone scan, resolution of abdominal lymph node
        disease by CT scan, and improvement in pain due to bone metastases,
        respectively.

   --   Reported at the ASCO Gastrointestinal Cancer Symposium in January
        2007, follow-up data from a Phase 2 clinical trial of GVAX
        immunotherapy for pancreatic cancer in 60 patients with operable
        pancreatic cancer who received the immunotherapy after surgical
        resection of their tumor and adjuvant radiation and chemotherapy.
        The updated results showed a median survival of 26.8 months.  This
        compares favorably with published, historical data from multiple
        single-arm and randomized studies in patients undergoing pancreatic
        cancer surgery and adjuvant therapy for whom the median survival has
        been reported to be in the range of 17 to 22 months, including the
        most recently reported results for gemcitabine chemotherapy.

   --   Reported at the American Association for Clinical Research meeting
        in April 2007, immune response data from two previously conducted
        Phase 2 clinical trials of GVAX immunotherapy for prostate cancer.
        Evaluation of antibody responses in patients with advanced prostate
        cancer from these studies shows that the GVAX cell-based
        immunotherapy induces antibody responses to a broad array of
        prostate cancer-associated antigens, including some not previously
        known to be associated with prostate cancer.  In addition, the
        antibody responses to this non patient-specific product were
        predominantly patient-specific and unique from patient to patient,
        indicating the potential advantage of a cell-based multi-antigen
        product such as GVAX to generate the broadest and most relevant
        immune response.

   --   Raised gross proceeds of $60 million in a registered direct offering
        of 10.8 million shares of common stock at a price of $5.55 per share
        with selected institutional investors.  In conjunction with the
        offering, the company issued warrants to purchase 2.2 million shares
        of common stock at a price of $7.18 per share.

   --   Entered into a new Committed Equity Financing Facility with
        Kingsbridge Capital Limited in February 2007 pursuant to which
        Kingsbridge committed to purchase, subject to certain conditions, up
        to $75 million of our common stock.  The company had previously
        raised $35.0 million in a similar transaction with Kingsbridge.

   --   Reached a favorable settlement with the IRS regarding the audit of
        the company's 2000 tax return.  The settlement with the IRS is for
        approximately $3.5 million in taxes and interest and results in a
        decrease in accrued income tax liabilities of approximately $21
        million in taxes and interest.
