Infinity Provides Company Update and Reports Third Quarter 2010 Financial Results

CAMBRIDGE, Mass., Nov. 9, 2010 (GLOBE NEWSWIRE) -- Infinity Pharmaceuticals, Inc. (Nasdaq:INFI) today highlighted its recent business and clinical progress, and announced third quarter 2010 financial results.

"We recently reported several important milestones, including encouraging results from our Phase 1 study of IPI-926 in patients with solid tumor malignancies and Purdue and Mundipharma's decision to exercise rights to develop and commercialize our FAAH program worldwide," stated Adelene Q. Perkins, president and chief executive officer of Infinity. "With a solid financial position and an expanded management team that adds breadth and expertise, we are well-positioned to move our products through development and to patients."

Third quarter highlights and recent developments include the following:

• Presentation of Phase 1 Data of IPI-926 at ESMO: Encouraging Phase 1 data of IPI-926, a novel Smoothened antagonist, were presented at the European Society of Medical Oncology (ESMO) Congress. The presentation showed that IPI-926 was well-tolerated and demonstrated clinical activity in patients with basal cell carcinoma. A Phase 1 study of IPI-926 in solid tumors and a Phase 1b/2 study in combination with Gemzar^® (gemcitabine) in patients with previously untreated, metastatic pancreatic cancer are ongoing.
   
• Publication of Phase 2 Data of IPI-504 in Non-Small Cell Lung Cancer: Data from a Phase 2 study of IPI-504 in a molecularly defined cohort of patients with non-small cell lung cancer (NSCLC) were published in the Journal of Clinical Oncology (Sequist et. al., J Clin Oncol. doi: 10.1200/JCO.2010.30.8338, 2010). In the study, IPI-504 was generally well-tolerated and demonstrated clinical activity, particularly among patients with oncogenic anaplastic lymphoma kinase (ALK) gene rearrangements. A Phase 1b trial of IPI-504 in combination with Taxotere^® (docetaxel) in patients with advanced solid tumors and an investigator sponsored trial of IPI-504 in NSCLC patients with ALK rearrangements are ongoing.
   
• Announcement of Phase 1 Data of Single-Dose Study of IPI-940: Infinity reported data from the Phase 1 single-dose study of its fatty acid amide hydrolase (FAAH) inhibitor, IPI-940, in healthy adult volunteers. In the study, administration of IPI-940 resulted in marked FAAH inhibition and increased anandamide levels and was well-tolerated, with no observed dose-limiting toxicities. Additional Phase 1 development of IPI-940 is ongoing.
   
• Announcement of Purdue and Mundipharma's Decision to Exercise Rights to Develop and Commercialize FAAH Program Worldwide: Infinity announced that Purdue Pharmaceutical Products L.P. and its independent associated company, Mundipharma International Corporation Ltd., exercised rights to develop and commercialize Infinity's FAAH program worldwide. Purdue is planning to initiate Phase 2 studies of IPI-940 in 2011.
   
• Expansion of Executive Leadership Team: Infinity announced the appointment of Pedro Santabarbara, M.D., Ph.D., as chief medical officer and Elizabeth Trehu, M.D., as vice president, product development and medical affairs. In addition, as of December 31, 2010, Steven H. Holtzman, founder and current executive chair of Infinity's Board of Directors, will transition to the role of non-executive chair of the Board.

• Total revenue for the third quarter of 2010 was $22.2 million, compared to $13.8 million for the same period in 2009. In the third quarter of 2010, revenue was comprised of $21.5 million for reimbursed research and development (R&D) services and $0.7 million from the amortization of deferred revenue associated with the grant of rights and licenses under Infinity's strategic alliance with Purdue and Mundipharma, compared to $13.1 million and $0.7 million, respectively, for the same period in 2009.

R&D expense for the third quarter of 2010 included a one-time expense of $13.5 million related to the acquisition of global development and commercialization rights to Intellikine, Inc.'s portfolio of inhibitors of the delta and gamma isoforms of phosphoinositide-3-kinase. The increase in R&D expense for the third quarter of 2010 compared to the same period in 2009 was also associated with increased pharmaceutical development and clinical development activities for IPI-926 and IPI-940. Reimbursed expenses related to Infinity's alliance with Purdue and Mundipharma are recorded as R&D expense, as well as collaborative R&D revenue.
   
• General and administrative expense for the third quarter of 2010 was $5.0 million, compared to $4.6 million for the same period in 2009.

Financial Guidance

As a result of reimbursement for activities associated with the transition of the FAAH program to Purdue and Mundipharma, Infinity recently adjusted financial expectations for its anticipated year-end cash and investments balance. Infinity expects to end 2010 with total cash and investments of $90-$100 million, revised from an earlier expectation of $85-$95 million. Thus, Infinity now anticipates a cash burn of between $30-$40 million during 2010, revised from an earlier cash burn expectation of $35-$45 million.

In the absence of additional funding or business development activities, and based on current operating plans, Infinity expects that its current cash and investments, together with R&D funding from Purdue and Mundipharma and the $50 million line of credit made available by Purdue Pharma L.P., remain sufficient to fund the company's operations into 2013. The company believes that these resources will enable Infinity to reach key development milestones and continue evaluating additional external opportunities to strategically enhance its pipeline.
