WESTMINSTER, Colo.--(BUSINESS WIRE)--Nov. 3, 2009-- Allos Therapeutics, Inc. (Nasdaq: ALTH) today reported results for the third quarter of 2009. For the three months ended September 30, 2009, the Company reported a net loss of $18.7 million, or ($0.21) per share. This compares to a net loss of $13.2 million, or ($0.16) per share, for the third quarter of 2008. For the nine months ended September 30, 2009, the Company reported a net loss of $50.6 million, or ($0.58) per share, compared to a net loss of $37.0 million, or ($0.50) per share, for the same period last year. Net cash used in operating activities, together with the $5.8 million milestone payment under our license agreement for FOLOTYN^TM (pralatrexate injection), was $47.8 million for the nine months ended September 30, 2009. Cash, cash equivalents and investments in marketable securities as of September 30, 2009 were $84.1 million. In October 2009, the Company received net proceeds of approximately $93.0 million from a public offering of 14 million shares of the Company’s common stock.

“During the quarter, we achieved a significant milestone by obtaining accelerated approval for FOLOTYN for use as a single agent for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma,” said Paul L. Berns, president and chief executive officer of Allos Therapeutics. “Importantly, this represents our first U.S. indication and marks our emergence as a commercial oncology company. With a prioritized product development and commercialization plan for FOLOTYN and a solid financial position, we believe we have established a strong foundation for continued progress.”

Recent Highlights

• Announced the U.S. Food and Drug Administration (FDA) granted accelerated approval for FOLOTYN for use as a single agent for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma (PTCL) on September 24, 2009. This indication is based on overall response rate. Clinical benefit such as improvement in progression free survival or overall survival has not been demonstrated. FOLOTYN is the first and only drug approved by the FDA for this indication and represents a new treatment option for patients with relapsed or refractory PTCL.
• Announced FOLOTYN availability for commercial sale in the U.S. on October 5, 2009. The Company intends to market and sell FOLOTYN in the U.S. through its commercial organization, which includes 25 sales specialists that the Company plans to increase to approximately 50 specialists in advance of the planned commercial launch of FOLOTYN in January 2010.
• Established a patient assistance program named ASAP (Allos Support for Assisting Patients) to provide reimbursement resources for the uninsured, underinsured and insured and reimbursement support for health care professionals.
• Received notification from the National Comprehensive Cancer Network (NCCN) that it has updated the NCCN Clinical Practice Guidelines in Oncology™ for Non-Hodgkin’s Lymphomas to include FOLOTYN as a suggested treatment regimen for patients with second-line PTCL.
• Completed patient enrollment in the Company's investigational Phase 2b, randomized, international, multi-center clinical trial comparing pralatrexate and erlotinib (Tarceva®) in patients with Stage IIIB/IV non-small cell lung cancer (NSCLC) who are, or have been, cigarette smokers who have failed treatment with at least one prior platinum-based chemotherapy regimen. The objective of this Phase 2b trial is to assess the treatment effect of pralatrexate in certain pre-specified subsets of patients with advanced NSCLC where the Company believes the agent has the potential to provide clinical benefit. Patient enrollment was initiated in January 2008 and was completed in July 2009, having enrolled 201 patients. The Company currently expects to report top line results from this trial in the first half of 2010.
• Initiated patient enrollment in an investigational Phase 2 study of FOLOTYN in patients with aggressive relapsed or refractory B-cell non-Hodgkin’s lymphoma. This single-arm, open-label, multi-center study will seek to enroll approximately 27 evaluable patients in up to 10 investigative sites worldwide. The primary endpoint of the study is objective response rate (complete and partial response) per International Workshop Criteria. Secondary endpoints include duration of response, progression free survival, overall survival, and the safety and tolerability of FOLOTYN.
• Strengthened the Company's balance sheet with an underwritten public offering of 14 million shares of newly issued common stock in October, resulting in net proceeds of approximately $93.0 million after underwriting discounts, commissions and other estimated offering expenses.

2009 Financial Guidance

The Company reaffirms prior financial guidance that net cash use in operating activities, together with the $5.8 million milestone payment under the Company’s license agreement for FOLOTYN as discussed below, is expected to approximate $65 million to $70 million for the year ending December 31, 2009. The Company’s financial guidance for 2009 includes the phase-in of key investments associated with its commercial, medical affairs and manufacturing operations in preparation for its planned commercial launch of FOLOTYN in January 2010, and the $1.5 million and $5.8 million milestone payments under the Company’s license agreement for FOLOTYN paid upon FDA acceptance and approval of the Company’s New Drug Application, respectively, during the nine months ended September 30, 2009. The $5.8 million milestone payment was recorded as an intangible asset and in net cash used in investing activities as of and for the nine months ended September 30, 2009, respectively.

Financial projections entail a high level of uncertainty due to, among other factors, the variability involved in predicting clinical trial initiation timelines, enrollment rates and results, and the cost of commercial activities.

Patients should be instructed to take folic acid (1.0 -1.25 mg orally on a daily basis) and receive vitamin B₁₂ (1 mg intramuscularly every 8-10 weeks) to potentially reduce treatment-related hematological toxicity and mucositis.
