Allos Therapeutics Reports First Quarter 2007 Financial Results

WESTMINSTER, Colo., May 8  /PRNewswire-FirstCall/ -- Allos Therapeutics, Inc. (NASDAQ:ALTH) today reported financial results for the first quarter of 2007.  For the three months ended March 31, 2007, the Company reported a net loss of $8.4 million, or ($0.14) per share.  This compares to a net loss of $7.1 million, or ($0.13) per share, for the first quarter of 2006.  Cash, cash equivalents, and investments in marketable securities as of March 31, 2007 were $75.5 million.

Paul L. Berns, President and Chief Executive Officer, stated: "During the quarter we continued to make important progress in advancing our product development programs, notably through the successful completion of the first interim safety assessment for our pivotal Phase 2 PROPEL trial of PDX.  We also strengthened our leadership team through the appointment of seasoned industry executives to our senior management team and Board of Directors and improved our financial position through the completion of our underwritten offering of common stock in February.  We believe these clinical development and organizational advances position Allos for continued progress through the balance of the year."

  Product Portfolio Update:

  PDX (pralatrexate):


PDX is a novel, small molecule chemotherapeutic agent that inhibits dihydrofolate reductase, or DHFR, a folic acid (folate)-dependent enzyme involved in the building of nucleic acid, or DNA, and other processes.  PDX is currently under evaluation in patients with lymphoma and non-small cell lung cancer.

  *  In January 2007, an independent Data Monitoring Committee (DMC)
     completed a planned interim analysis of safety data from the Company's
     pivotal Phase 2 PROPEL trial of PDX in patients with relapsed or
     refractory peripheral T-cell lymphoma, and recommended that the trial
     continue per the protocol.  The interim assessment was based upon an
     evaluation of the first ten patients enrolled in the study who
     completed at least one cycle of treatment with PDX.  No major patient
     safety concerns were identified by the DMC.  In accordance with the
     study's design, an interim analysis of efficacy data will be conducted
     after 35 patients have completed at least one cycle of treatment with
     PDX, which is currently expected to occur in the second half of 2007.
     The DMC will assess patient safety as part of the 35 patient response
     assessment and again after 65 patients have completed at least one
     cycle of treatment.  The Company currently anticipates that study
     enrollment at up to 35 centers in the United States, Canada and Europe
     will be completed by the third quarter of 2008.

  *  In April 2007, the Commission of the European Communities, with a
     favorable opinion of the Committee for Orphan Medicinal Products of the
     European Medicines Agency (EMEA) granted orphan medicinal product
     designation to PDX for the treatment of patients with peripheral T-cell
     lymphoma (PTCL).

  EFAPROXYN(TM) (efaproxiral):


EFAPROXYN is the first synthetic small molecule designed to sensitize hypoxic, or oxygen-deprived, areas of tumors during radiation therapy by facilitating the release of oxygen from hemoglobin, the oxygen-carrying protein contained within red blood cells, and increasing the level of oxygen in tumors.  EFAPROXYN is currently under evaluation in patients with brain metastases originating from breast cancer, and in patients with primary non-small cell lung cancer and cervical cancer.

  *  Patient enrollment in ENRICH, the Company's pivotal Phase 3 study of
     EFAPROXYN plus whole brain radiation therapy in women with brain
     metastases originating from breast cancer was completed in September
     2006.  Patients were randomized 1:1 to receive standard whole brain
     radiation therapy, 3 Gy fractions for 10 days plus supplemental oxygen,
     with or without EFAPROXYN.  At the time of randomization patients were
     stratified by KPS and known liver metastases.  The primary endpoint of
     the trial is survival, which will be compared between treatment arms
     using the stratified log rank test.  The Company plans to conduct the
     final analysis of safety and efficacy data from this trial following
     the occurrence of 282 eligible patient deaths, which is expected to
     occur in mid-2007.  If the results are positive, the Company intends to
     submit an amendment to its previously filed new drug application to the
     FDA as expeditiously as possible.

  RH1:


RH1 is a novel small molecule chemotherapeutic agent that is bioactivated by the enzyme DT-diaphorase, or DTD, which is over-expressed in many tumors relative to normal tissue, including lung, colon, breast and liver tumors. RH1 was recently the subject of a Phase 1 study in patients with various solid tumors.

  *  Sarah Danson, Ph.D., of Christie Hospital and the Paterson Institute
     for Cancer Research, Manchester, UK is scheduled to present a poster
     presentation titled "Final results of a phase I clinical trial of the
     bioreductive drug RH1" at the American Society of Clinical Oncology
     Annual Meeting on June 4, 2007.

  Corporate events:

  *  In April 2007, the Company appointed Jeffrey R. Latts, former Executive
     Vice President and Chief Medical Officer of Exelixis, Inc., to its
     Board of Directors.
  *  In March 2007, the Company appointed Pablo J. Cagnoni, M.D. as Senior
     Vice President, Chief Medical Officer.
  *  In February 2007, the Company closed an underwritten offering of
     9,000,000 shares of its common stock, resulting in aggregate net
     proceeds to the Company of approximately $50.3 million.
  *  In January 2007, the Company appointed William R. Ringo, former
     President and CEO of Abgenix Inc., to its Board of Directors.
