R&D Day Highlights

Duvelisib

• 120th patient enrolled in DYNAMO: In September, Infinity announced that the 120th patient had been enrolled in DYNAMO, a global, Phase 2 open-label, single-arm, monotherapy study of duvelisib (25 mg BID) in patients with iNHL whose disease is refractory to rituximab and to either chemotherapy or radioimmunotherapy. The primary endpoint is overall response rate. Topline data is anticipated in the third quarter of 2016, and Infinity anticipates the submission of global regulatory filings by the end of 2016. This enrollment milestone triggered an obligation for AbbVie Inc. to pay Infinity a $130 million payment. AbbVie is Infinity's global development and commercial partner for duvelisib in oncology.

• DUO™ enrollment on track for completion by the end of 2015:  Infinity expects that DUO, a Phase 3 randomized monotherapy study designed to evaluate the safety and efficacy of duvelisib (25mg BID) compared to ofatumumab in approximately 300 patients with relapsed/refractory chronic lymphocytic leukemia (CLL), will complete patient enrollment by the end of 2015. The primary endpoint of this study is progression-free survival.

• Clinical study of duvelisib + venetoclax expected to begin by end of 2015: Infinity anticipates that AbbVie will initiate the first clinical study of duvelisib and venetoclax, a selective first-in-class BCL-2 inhibitor, by the end of 2015. This Phase 1b/2 trial of duvelisib and venetoclax will be designed to evaluate the safety and activity of the combination across a range of hematologic malignancies.

• BRAVURA study expected to begin by the end of 2015: Infinity also announced plans to initiate BRAVURA, a Phase 3, double-blind, placebo-controlled study in patients with relapsed iNHL, in the fourth quarter of 2015. BRAVURA is designed to evaluate the safety and efficacy of duvelisib plus rituximab and bendamustine (RB) compared to placebo plus RB in approximately 600 patients. The primary endpoint is progression-free survival.
  
  Infinity is planning to request advice from the U.S. Food and Drug Administration (FDA) to determine if BRAVURA, as designed, can serve as a confirmatory study if DYNAMO supports an accelerated approval.

• FRESCO study expected to begin by the end of 2015: Infinity announced plans to initiate FRESCO, a Phase 2 study in patients with relapsed/refractory FL, in the fourth quarter of 2015. FRESCO is designed to evaluate the safety and efficacy of duvelisib plus rituximab versus rituximab in combination with chemotherapy in approximately 200 patients. The primary endpoint is progression-free survival.

IPI-549

• IPI-549 demonstrates preclinical anti-tumor activity: Preclinical data show that IPI-549, a selective PI3K-gamma inhibitor for the treatment of solid tumors, has the potential to heighten an anti-cancer response by targeting macrophages in the immune-suppressive tumor microenvironment and may have the potential to treat a broad range of solid tumors. IPI-549 has demonstrated dose-dependent, single-agent, anti-tumor activity in multiple solid tumor models, including murine models of lung, colon and breast cancer. Additionally, mice treated with IPI-549 in combination with checkpoint inhibitors showed greater tumor growth inhibition than either treatment as a monotherapy. Preclinical in vivo data also demonstrated that T-cells are required for the anti-tumor activity of IPI-549, which is a hallmark of immunotherapy. These data were presented at CRI-CIMT-EATI-AACR - The Inaugural International Cancer Immunotherapy Conference in September 2015.

• First Phase 1 study of IPI-549 expected to begin in the first quarter of 2016: Infinity expects to file an Investigational New Drug (IND) Application for IPI-549 by the end of 2015 and begin a Phase 1 clinical study of IPI-549 in the first quarter of 2016. The Phase 1 study will be designed to explore the safety and activity of IPI-549 and include a dose escalation phase evaluating IPI-549 as a monotherapy as well as a dose-escalation phase evaluating IPI-549 in combination with anti–PD-1 antibody therapy. An expansion phase is planned in patients with selected solid tumors, including non-small cell lung cancer (NSCLC) and melanoma.

Corporate Updates

• William Bertrand to join Infinity as executive vice president, general counsel: Infinity announced today that William Bertrand will join Infinity as executive vice president, general counsel, effective October 19, 2015. Prior to Infinity, Mr. Bertrand held various roles of increasingly responsibility at Salix Pharmaceuticals, Inc. (a subsidiary of Valeant Pharmaceuticals, Inc.) and most recently served as senior vice president, general manager at Salix where he was responsible for its commercial business as well as the transition and integration of Salix into Valeant. From 2001 to 2013, Mr. Bertrand held positions of increasing responsibility at MedImmune, Inc., serving as its first and only general counsel from 2003 to 2013, prior to and following its sale to AstraZeneca PLC in 2008. Prior to MedImmune, Mr. Bertrand served as associate general counsel at Pharmacia Corporation. He earned a B.S. in Biology from Wayne State University and a J.D. from the University of Wisconsin-Madison.

• Infinity updates 2015 financial guidance:  Due to changes in the anticipated timing of the initiation of planned clinical studies as well as slower than expected enrollment in DYNAMO+R, Infinity today provided the following updated financial guidance for 2015:
  • Revenue: Infinity expects revenue to range from $100 million to $120 million, compared to prior expectations of $105 million to $125 million.
  • Net Loss: Infinity expects net loss for 2015 to range from $125 million to $145 million, compared to prior expectations of $190 million to $210 million.
  • Cash and Investments: Infinity now expects to end 2015 with a year-end cash and investments balance ranging from $230 million to $250 million, compared to prior expectations of $145 million to $165 million. This year-end cash and investments includes the $130 million milestone payment from AbbVie associated with the completion of patient enrollment in DYNAMO.

Infinity plans to report its third quarter 2015 financial results in early November.

About Duvelisib

Duvelisib is an oral, dual inhibitor of phosphoinositide-3-kinase (PI3K)-delta and PI3K-gamma, two proteins with predominantly non-overlapping roles known to support the growth and survival of malignant B-cells.i  Preclinical data suggest that PI3K-delta signaling can lead to the proliferation of malignant B-cells, and both PI3K-gamma and PI3K-delta play a role in the formation and maintenance of the supportive tumor microenvironment.ii Duvelisib is the only investigational PI3K-delta,gamma inhibitor in Phase 3 clinical development and has the potential to be a first-in-class treatment for certain types of hematologic malignancies, or blood cancers. AbbVie and Infinity Pharmaceuticals, Inc. are jointly developing duvelisib in oncology.

Duvelisib is being evaluated in registration-focused studies, including DYNAMO™, a Phase 2 study in patients with refractory indolent non-Hodgkin lymphoma, DYNAMO+R, a Phase 3 study in patients with previously treated follicular lymphoma, and DUO™, a Phase 3 study in patients with relapsed/refractory chronic lymphocytic leukemia.

About IPI-549

IPI-549 is an orally administered immuno-oncology development candidate that selectively inhibits PI3K-gamma. IPI-549 inhibits immune suppressive macrophages within the tumor microenvironment, whereas other immunotherapies such as checkpoint modulators more directly target immune effector cell function. As such, IPI-549 may have the potential to treat a broad range of solid tumors and represents a potentially complementary approach to restoring anti-tumor immunity in combination with other immunotherapies such as checkpoint inhibitors.

Duvelisib and IPI-549 are investigational compounds and their safety and efficacy have not been evaluated by the U.S. Food and Drug Administration or any other health authority.
