WESTMINSTER, Colo., Nov. 9 /PRNewswire-FirstCall/ -- Allos Therapeutics, Inc. today reported financial results for the third quarter of 2005. For the three months ended September 30, 2005, the Company reported a net loss of $4.8 million, or $0.09 per share. This compares to a net loss of $4.6 million, or $0.15 per share, for the three months ended September 30, 2004. For the nine months ended September 30, 2005, the Company reported a net loss of $15.5 million, or $0.36 per share, compared to a net loss of $16.9 million, or $0.54 per share, for the same period last year. Cash, cash equivalents, and investments in marketable securities as of September 30, 2005 amounted to $59.4 million. Product Portfolio Update: EFAPROXYN(TM) (efaproxiral): * ENRICH, the Company's Phase 3 study of the radiation sensitizer EFAPROXYN in patients with brain metastases originating from breast cancer, continues to progress in line with Company expectations. The Company expects to complete patient enrollment in this trial during the second half of 2006 and report preliminary results approximately six months thereafter. * In September 2005, the Company announced the publication of results from its Phase 2 multi-center study of EFAPROXYN in patients with unresectable non-small cell lung cancer (NSCLC) receiving sequential chemoradiotherapy (S-CRT). Results from the study, which were reported in the September 1st edition of the Journal of Clinical Oncology, suggest that the addition of EFAPROXYN to S-CRT may improve survival over S-CRT alone without increasing radiation toxicity rates. * In October 2005, the Company withdrew its European Marketing Authorization Application (MAA) for its investigational radiation sensitizer REVAPROXYN(TM) (efaproxiral, EFAPROXYN(TM) in the United States) for use as an adjunct to whole brain radiation therapy for the treatment of patients with brain metastases originating from breast cancer. The Company believes that the ongoing ENRICH trial, if positive, together with other supporting data, should provide the additional data necessary to support the filing of a new MAA and the future approval of EFAPROXYN for the treatment of brain metastases originating from breast cancer in Europe. * Charles Scott, Ph.D., CBS Squared, is scheduled to present a quality adjusted survival analysis of the Phase 3 REACH study of EFAPROXYN in patients with brain metastases in a poster presentation titled "Improved survival, quality of life and quality-adjusted survival in breast cancer patients treated with efaproxiral + whole brain radiation therapy for brain metastases" at the San Antonio Breast Cancer Symposium on December 10, 2005. PDX (pralatrexate): * Enrollment in a Phase 1/2 study of PDX in patients with relapsed or refractory aggressive lymphoproliferative malignancies continues to progress in line with Company expectations. The Company expects to complete patient enrollment in the Phase 1 portion of this trial in the fourth quarter of 2005. * In January 2005, the Company initiated a Phase 1 dose escalation study of PDX with vitamin B12 and folic acid supplementation in patients with previously treated advanced NSCLC. The Company currently expects to complete patient enrollment in this trial in 2006. RH1: * Enrollment in a Phase 1 dose escalation study of RH1 in patients with advanced solid tumors continues to progress in line with Company expectations. The Company currently expects to complete enrollment in this trial in the fourth quarter of 2005. Sarah Danson, M.D., Department of Medical Oncology, Christie Hospital, is scheduled to report updated clinical and PK/PD data from an on-going Phase 1 study of RH1 in patients with advanced solid tumors in a poster presentation titled "Phase 1 Pharmacokinetic (PD) trial of the bioreductive drug RH1" at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics on November 17, 2005. Corporate Highlights: * In October 2005, the only remaining securities class action lawsuit that had been brought against the Company and one of its officers in May 2004 was dismissed with prejudice. In an opinion dated October 20, 2005, the United States District Court for the District of Colorado concluded that the plaintiff's complaint failed to meet the legal pleading requirements applicable to its alleged claims. The plaintiff has until November 19, 2005 to determine whether it will appeal the decision to the U.S. Court of Appeals for the Tenth Circuit. * In July 2005, a shareholder of the Company commenced a stockholder's derivative action in the United States District Court for the District of Colorado against several current and former directors of the Company, naming the Company as a nominal defendant. The factual allegations in the derivative action were substantially the same as the factual allegations in the purported securities class action lawsuit filed in May 2004. On November 2, 2005, the court granted the parties joint motion for voluntary dismissal and dismissed the case without prejudice.
