Infinity Provides Company Update and Reports Full-Year 2014 Financial Results

CAMBRIDGE, Mass.--(BUSINESS WIRE)--

Infinity Pharmaceuticals, Inc. INFI today announced its full-year 2014 financial results and ongoing progress with duvelisib (IPI-145), an oral, dual inhibitor of phosphoinositide-3-kinase (PI3K)-delta and PI3K-gamma. Infinity anticipates that it will report topline data from DYNAMO^TM, a Phase 2 study of duvelisib in patients with refractory indolent non-Hodgkin lymphoma (iNHL), in the second half of 2015 following the completion of patient enrollment in the first half of the year. Infinity also expects to complete enrollment of DUO^TM, a Phase 3 study of duvelisib in patients with relapsed/refractory chronic lymphocytic leukemia (CLL), in the second half of 2015. Additionally, Infinity anticipates that three company-sponsored clinical studies of duvelisib will be initiated in 2015, including the first clinical study of duvelisib in combination with venetoclax (ABT-199).

"In 2014, Infinity continued to advance duvelisib in registration-focused studies and entered a global collaboration with AbbVie to expand and accelerate the development and commercialization of duvelisib in oncology. We continue to be encouraged by the clinical activity and early signs of durability that we have observed in our Phase 1 study of duvelisib, which complements our growing scientific understanding of the potential impact that dual inhibition of PI3K-delta and PI3K-gamma may have on thwarting the growth and survival of certain blood cancers," stated Adelene Perkins, chair, president and chief executive officer at Infinity. "Our progress in 2014 positions us to achieve several important milestones this year as we work toward our goal of building a fully integrated biotechnology company. Importantly, in the second half of this year we expect to report topline data from DYNAMO, which could help to establish duvelisib as the best oral therapy for the treatment of iNHL. Two important components of our strategy to achieve better patient outcomes include the inhibition of both the delta and gamma isoform of PI3K with duvelisib and the combination of novel therapies. We expect that the first clinical study of duvelisib in combination with venetoclax will be initiated this year."

Recent highlights include the following:

• Initiated DYNAMO+R, a Phase 3 study in patients with previously treated follicular lymphoma: In December 2014, Infinity announced the initiation of DYNAMO+R, a Phase 3, randomized, double-blind, placebo-controlled study comparing duvelisib plus Rituxan^® (rituximab) to placebo plus Rituxan in approximately 400 patients with previously treated follicular lymphoma. The primary endpoint of the study is progression-free survival.
• Initiated two additional studies of duvelisib: As part of Infinity's development strategy to demonstrate the therapeutic potential of duvelisib in multiple indications and lines of treatment, the company today announced that it has initiated its Phase 1b/2 clinical study in patients with previously untreated follicular lymphoma, which is designed to evaluate the safety and activity of duvelisib in combination with Gazyva^® (obinutuzumab) or Rituxan. The company also announced today that it has initiated the Phase 1b clinical study of duvelisib in combination with Gazyva in patients with CLL whose disease has progressed following treatment with a Bruton's tyrosine kinase (BTK) inhibitor.
• Announced encouraging new clinical data of duvelisib at American Society of Hematology Annual Meeting (ASH): In December 2014, Infinity reported updated data from a Phase 1 monotherapy study of duvelisib, which showed activity among patients with relapsed/refractory iNHL. Data demonstrated that duvelisib administered as a monotherapy at 25 mg twice daily (BID) was clinically active, with a 72 percent overall response rate (13 of 18 evaluable patients) and a 33 percent complete response rate (6 of 18 evaluable patients). Among patients with follicular lymphoma, the overall response rate was 69 percent (9 of 13 evaluable patients), including a 38 percent complete response rate (5 of 13 evaluable patients). The median progression free survival and median overall survival had not yet been reached, with 69 percent progression-free survival and 89 percent overall survival at 24 months. The majority of adverse events were Grade 1 or 2, reversible and/or clinically manageable.
  
  During the meeting, Infinity also reported updated Phase 1 monotherapy data of duvelisib dosed at 25 mg BID in patients with relapsed/refractory CLL demonstrating that duvelisib treatment led to an overall response rate of 57 percent, including one complete response, and adverse events were mostly Grade 1 or 2, reversible and/or clinically manageable. Additional data reported from the Phase 1 study of duvelisib included new data showing preliminary activity and safety in patients previously treated with ibrutinib and updated data showing activity and safety in patients with relapsed/refractory T-cell lymphoma.
• Announced encouraging new preclinical results of duvelisib at ASH: In December 2014, Infinity also announced preclinical translational data providing new insights into the roles of PI3K-delta and PI3K-gamma in malignant B-cell growth and survival. Research presented supports the hypothesis that PI3K-delta is important in the proliferation of malignant B-cells, and that both PI3K-delta and PI3K-gamma play an important role in the formation and maintenance of the supportive tumor microenvironment. These data, taken together, suggest that PI3K-delta and PI3K-gamma may have complementary effects on malignant B-cell growth and survival.
• Reported topline results from a Phase 2 study of duvelisib in rheumatoid arthritis: In January, Infinity announced that ASPIRA, a Phase 2 study of duvelisib, an oral inhibitor of phosphoinositide-3-kinase (PI3K)-delta and PI3K-gamma, with background methotrexate in patients with moderate-to-severe rheumatoid arthritis (RA) did not meet its primary endpoint, ACR20 response rate at 12 weeks. Infinity will not proceed with further clinical development in RA with duvelisib or IPI-443, its second PI3K-delta,gamma inhibitor. Infinity expects that any further development of IPI-443 in inflammatory diseases would be conducted through out-licensing or partnering efforts.

2015 Development Milestones

Infinity anticipates achieving the following development milestones in 2015:

Novel Duvelisib Combinations

• Initiation by AbbVie of the first clinical study of duvelisib in combination with venetoclax

Full-Year 2014 Financial Results

• At December 31, 2014, Infinity had total cash, cash equivalents and available-for-sale securities of $333.2 million, compared to $214.5 million at December 31, 2013, and $379.5 million at September 30, 2014.

• R&D expense for full-year 2014 was $143.6 million, compared to $99.8 million for 2013. The increase in R&D expenses in 2014 compared to 2013 was primarily due to higher clinical development expenses for duvelisib.
• General and administrative expense was $29.3 million for the full-year 2014 and $27.9 million for the full-year 2013.
• Net loss for full-year 2014 was $17.4 million, or a basic and diluted loss per common share of $0.36, compared to $126.8 million, or a basic and diluted loss per common share of $2.64 for 2013.
