Infinity Reports R&D Highlights and Announces First Quarter 2010 Financial Results

Infinity Maintains Financial Strength to Advance Its Innovative Product Pipeline


CAMBRIDGE, Mass., May 6, 2010 (GLOBE NEWSWIRE) -- Infinity Pharmaceuticals, Inc. (Nasdaq:INFI), an innovative drug discovery and development company, today reported recent research and development (R&D) highlights and announced first quarter 2010 financial results.

"Infinity is using its financial strength to aggressively develop its clinical pipeline. The recently initiated clinical study in our Hedgehog pathway inhibitor program with IPI-926 builds upon the data we have generated to date and the potential of this agent to address difficult to treat cancers," said Adelene Q. Perkins, president and chief executive officer, Infinity. "We continue to manage our product portfolio in a disciplined, data-driven manner in order to achieve our mission of delivering to patients innovative medicines that meaningfully impact their lives."

Hedgehog Pathway Inhibitor Program

Infinity recently announced the initiation of a Phase 1b/2 clinical trial evaluating IPI-926 in combination with Gemzar® (gemcitabine), a chemotherapy, in patients with previously untreated, metastatic pancreatic cancer. The Phase 1b portion of the study is a dose escalation, and once the recommended Phase 2 doses for IPI-926 and gemcitabine have been established, the Phase 2 portion of the trial will commence. The Phase 2 is an international, multi-center, randomized, double-blind study with a primary endpoint of overall survival. Secondary endpoints include progression free survival, time to progression, and overall response rate.

Infinity also recently presented new preclinical data at the American Association for Cancer Research Annual Meeting further demonstrating the potential of IPI-926 in a variety of solid tumors. In a xenograft model of pancreatic cancer, data reported showed that the combination of IPI-926 and Abraxane® (nab-paclitaxel), a chemotherapy, resulted in significant tumor growth inhibition and an increase in tumor perfusion by IPI-926, and demonstrated that IPI-926 may increase the activity of nab-paclitaxel through increased drug delivery. Additionally, data were presented from two separate studies demonstrating that IPI-926 may delay tumor re-growth after regression of the tumor by either chemotherapy or targeted therapy. In a xenograft model of castration resistant prostate cancer, data reported showed that administration of IPI-926 in combination with Taxotere® (docetaxel), a chemotherapy, led to a statistically significant delay in tumor re-growth. Further, in multiple xenograft models of EGFR-mutated non-small cell lung cancer (NSCLC), Infinity showed that IPI-926, when administered after treatment with a targeted therapy, Iressa® (gefitinib), significantly delayed tumor re-growth.

Infinity is also evaluating IPI-926 in a Phase 1 clinical trial in patients with advanced solid tumors, and anticipates reporting preliminary data from this study later this year.

Hsp90 Chaperone Inhibitor Program

Infinity is evaluating its i.v.-administered Hsp90 chaperone inhibitor, IPI-504, in a Phase 2 trial in combination with Herceptin® (trastuzumab) in patients with HER2-positive metastatic breast cancer and in a Phase 1b trial in combination with docetaxel focused on patients with NSCLC. Infinity anticipates presenting preliminary data from the breast cancer study in the second half of 2010. In addition, Infinity has completed enrollment in its single-agent trial of IPI-504 in patients with advanced NSCLC, and based on preliminary data showing a response rate in patients with wild-type EGFR expression, the company undertook an effort to better understand the molecular characteristics of the responding patients. Infinity anticipates that data from this research, along with final data from the NSCLC clinical trial, will be presented during the American Society for Clinical Oncology Annual Meeting in June 2010.

Infinity is also evaluating its orally administered Hsp90 chaperone inhibitor, IPI-493, in a Phase 1 clinical trial in patients with advanced solid tumors. Infinity anticipates the commencement of active enrollment in a Phase 1 study in patients with advanced hematologic malignancies in the near term, and reporting data from its Phase 1 program with IPI-493 by the end of 2010.

FAAH Inhibitor Program

Infinity continues to make progress with its fourth clinical candidate, IPI-940, a selective, orally administered inhibitor of the fatty acid amide hydrolase (FAAH) enzyme for the potential treatment for a broad range of neuropathic and inflammatory pain conditions. IPI-940 is being evaluated in a Phase 1 program in normal, healthy volunteers that includes both single- and multiple-ascending dose studies. Infinity anticipates completing Phase 1 development of IPI-940 in 2010.

First Quarter 2010 Financial Results

  • Infinity ended the first quarter of 2010 with $126.3 million in cash and investments.
  • Total revenue for the first quarter of 2010 was $16.0 million, comprised of $15.3 million for reimbursed R&D services and $0.7 million from the amortization of deferred revenue associated with the grant of licenses under Infinity's strategic alliance with Purdue Pharmaceutical Products L.P. and Mundipharma International Corporation Ltd.
  • R&D expense was $19.4 million for the first quarter of 2010. Reimbursed expenses related to Infinity's alliance with Purdue and Mundipharma for the quarter are recorded as R&D expense, as well as collaborative R&D revenue. The primary driver of the remaining R&D expense was Infinity's investment in the development of its Hsp90 chaperone inhibitor program.    
  • General and administrative expense was $4.7 million for the first quarter of 2010.
  • Infinity's net loss for the first quarter of 2010 was $8.4 million. Basic and diluted loss per common share was $0.32.

Financial Guidance

Based on its 2010 R&D and business objectives, Infinity anticipates a cash burn of between approximately $25-35 million during 2010 and estimates a year-end cash and investments balance of between $95-105 million. This guidance does not include any amounts that Infinity may draw under the $50 million line of credit available from Purdue Pharma L.P. 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 proceeds from the line of credit, are sufficient to fund the company's operations into 2013 and enable the company to reach key development milestones and evaluate external opportunities to strategically enhance its pipeline.
