Cell Genesys Reports Second Quarter 2007 Results

SOUTH SAN FRANCISCO, Calif., Aug. 7 /PRNewswire-FirstCall/ — Cell Genesys, Inc. today reported financial results for the second quarter ended June 30, 2007. The company reported a net loss of $1.9 million, or $0.03 per fully diluted share, for the second quarter of 2007, compared with a net loss of $27.9 million, or $0.60 per fully diluted share, in the corresponding period of 2006.

The decrease in net loss reported in the second quarter of 2007 compared with the net loss for the corresponding period in the previous year is due to a favorable settlement with the Internal Revenue Service (IRS) in the second quarter of 2007 relating to the company’s 2000 tax return. The settlement resulted in a decrease of approximately $26.8 million in accrued income tax liabilities following a payment to the IRS of $3.3 million in federal tax and interest.

“We are very pleased with our recent business progress, most notably the completion of patient recruitment in the first of two ongoing Phase 3 trials of our lead product, GVAX immunotherapy for prostate cancer. This is a major milestone for this program and our business in general,” stated Stephen A. Sherwin, M.D., chairman and chief executive officer of Cell Genesys. “We are equally pleased that we have been able to maintain our financial strength as we advance this key development program with a successful equity financing during the quarter.”

Revenues for the second quarter ended June 30, 2007, were less than $0.1 million compared with revenues of $1.0 million for the corresponding period in 2006. The difference is due to the timing of revenue from existing licensing arrangements which varies from quarter to quarter.

The company’s research and development costs were $25.0 million for the second quarter of 2007 compared with $23.2 million for the corresponding period in 2006. The increase is primarily due to 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 $4.8 million for the second quarter of 2007 compared to $4.3 million for the corresponding period in 2006. This increase is primarily attributed to an increase in administrative expenses.

As of June 30, 2007, Cell Genesys had approximately $171.1 million in cash, cash equivalents and short-term investments compared to $154.1 million at December 31, 2006. The ending second quarter balance reflects gross proceeds raised since the beginning of 2007, including $12.5 million raised in the first quarter from the company’s Committed Equity Financing Facilities with Kingsbridge Capital Limited, and $60.0 million raised from a registered direct offering in the second quarter.

   Second Quarter and Other Recent Highlights    — Announced the completion of recruitment of over 600 patients into      VITAL-1, the first of two ongoing Phase 3 clinical trials of GVAX      immunotherapy for prostate cancer.   The multi-center, randomized,      controlled Phase 3 study in advanced prostate cancer will compare GVAX      cancer immunotherapy to Taxotere(R) (docetaxel) chemotherapy plus      prednisone in hormone refractory prostate cancer (HRPC) patients with      metastatic disease. The primary endpoint of the trial is an improvement      in survival.  The company estimates the timing of the pre-planned      interim analysis from the VITAL-1 trial to be in 2008, probably in the      first half of the year, and that there will be a sufficient number of      events required for the final analysis to follow sometime later in      2009.    — Reported updated clinical data for GVAX immunotherapy for prostate      cancer from the second of two, independent, multi-center Phase 2      clinical trials, which combined involved approximately 115 patients.      Data from these two trials showed a median survival of 34.9 months and      35.0 months, respectively, for the patients who received doses      comparable to the Phase 3 dose.   The results of the first trial were      published in the July 1, 2007, issue of Clinical Cancer Research.      These results exceeded the predicted survival of 22.5 months and 22.0      months, respectively, as determined by a seven point patient disease      characteristic nomogram.  Results from both studies also compare      favorably to the previously published median survival of 18.9 months      for metastatic HRPC patients treated with Taxotere chemotherapy plus      prednisone, the current standard of care.  The company’s ongoing      Phase 3 program is designed to confirm a potential survival benefit and      safety profile for GVAX immunotherapy for prostate cancer.    — Reported at the American Association for Cancer Research meeting in      April 2007, immune response data from the company’s 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.    — Announced three new clinical trials for GVAX immunotherapy for leukemia      that are now under way in collaboration with the Johns Hopkins Sidney      Kimmel Cancer Center. The new trials are based on encouraging results      in an initial Phase 2 study of the product in patients with chronic      myelogenous leukemia (CML) and include: a randomized Phase 2 trial in      56 patients with CML who have persistent molecular evidence of disease      following Gleevec(R) (imatinib) therapy that will compare the      combination of GVAX plus continued Gleevec to the combination of      interferon-alpha, GM-CSF plus continued Gleevec with respect to the      levels of bcr-abl, a well-established marker of residual leukemia.  In      addition, there will be an extension study of the initial Phase 2 trial      in patients with CML that will evaluate the efficacy of a second course      of GVAX in patients who failed to achieve a sustained complete response      and a Phase 1 trial in 18 patients with poor risk myelodysplastic      syndrome.    — Announced follow-up data from a Phase 2 clinical trial of GVAX      immunotherapy for pancreatic cancer that was conducted by the Johns      Hopkins Sidney Kimmel Cancer Center. The trial enrolled 60 patients      with operable pancreatic cancer who received GVAX after surgical      resection of their tumor and adjuvant radiation and chemotherapy. The      median overall survival for these patients was previously reported to      be 26.8 months, a result which compares favorably to the 17 to      22 months median survival results published from multiple studies in      patients undergoing pancreatic cancer surgery and adjuvant therapy. Of      note, 53 of the 60 patients were considered high risk, based on the      unfavorable finding that their cancer had spread to regional lymph      nodes. The new data included a median disease-free survival of      approximately 16 months which compares favorably to the 13 months      disease-free survival recently reported for gemcitabine adjuvant      therapy.    — Announced follow-up data from the ongoing Phase 1 clinical trial in      patients with advanced prostate cancer receiving GVAX immunotherapy for      prostate cancer administered in combination with ipilimumab (MDX-010),      a fully human anti-CTLA-4 antibody that is being jointly developed by      Medarex and Bristol-Myers Squibb Company. The new data reported      includes median follow-up of 18 months on the first 12 patients      enrolled in the trial. Of the six patients who have received the two      highest doses, antitumor activity has been observed in five patients,      including prostate-specific antigen (PSA) declines of greater than      50 percent that were maintained in four of these patients for at least      six months, with the longest response to date at approximately      16 months.  Clinical evidence of antitumor activity has been observed      in four of these five PSA responders, including complete resolution of      multiple lesions on bone scan in two patients, and resolution of      abdominal lymph node disease by CT scan and improvement in bone pain in      one patient each. The five patients with PSA declines experienced      either Grade 2 or 3 immune-mediated endocrine deficiencies similar in      type to those previously reported with ipilimumab therapy, and were      successfully treated with standard hormone replacement therapy and one      patient who received the highest dose of ipilimumab developed a Grade 3      dose-limiting pulmonary alveolitis that responded to steroid treatment.      Immunomonitoring studies showed that the combination therapy enhanced T      cell and dendritic cell activity, which was more pronounced at the      higher dose levels.    — Raised gross proceeds of $60.0 million in a registered direct offering      to institutional investors of 10.8 million shares of the company’s      common stock at $5.55 per share and warrants to purchase up to      2.2 million shares of the company’s common stock at a price of $7.18      per share with selected institutional investors.    — Reached a favorable settlement with the IRS regarding the audit of the      company’s 2000 tax return.  The settlement with the IRS was for      $3.3 million in taxes and interest and resulted in a decrease in      accrued income tax liabilities of $26.8 million.
