CAMBRIDGE, Mass.--()--Infinity Pharmaceuticals, Inc. (NASDAQ: INFI) today announced that new data for duvelisib (IPI-145), an oral inhibitor of phosphoinositide-3-kinase (PI3K)-delta and PI3K-gamma, will be presented at the American Society of Hematology (ASH) 2014 Annual Meeting, which is being held December 6-9 in San Francisco, CA.

Key results to be presented during the meeting include translational data showing the complementary effects of inhibiting both PI3K-delta and PI3K-gamma as well as updated data from the Phase 1 study evaluating the safety and activity of duvelisib in patients with relapsed/refractory indolent non-Hodgkin lymphoma (iNHL) and relapsed/refractory chronic lymphocytic leukemia (CLL). Updated Phase 1 data on the activity of duvelisib in patients with T-cell lymphoma will also be reported.

About the Development of Duvelisib for the Treatment of Blood Cancers

Infinity and AbbVie Inc. are developing duvelisib, an oral inhibitor of Class I PI3K-delta,gamma. The PI3Ks are a family of enzymes involved in multiple cellular functions, including cell proliferation and survival, cell differentiation, cell migration and immunity. The Class 1 PI3K-delta and PI3K-gamma isoforms are preferentially expressed in leukocytes, or white blood cells, where they have distinct and predominantly non-overlapping roles in key cellular functions, including cell proliferation, cell differentiation, cell migration and activation. Targeting PI3K-delta and PI3K-gamma may provide multiple opportunities to develop differentiated therapies for the treatment of hematologic malignancies.

In 2013, Infinity launched the DUETTSTM (Duvelisib Trials in Hematologic Malignancies) program, a worldwide investigation of duvelisib in blood cancers. As part of the DUETTS program, patient enrollment is ongoing in DYNAMOTM, a Phase 2 monotherapy study designed to evaluate the safety and efficacy of duvelisib in patients with refractory indolent non-Hodgkin lymphoma (iNHL) (ClinicalTrials.gov Identifier NCT01882803), and DUOTM, a Phase 3 monotherapy study designed to evaluate the safety and efficacy of duvelisib in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) (NCT02004522). DYNAMO+RTM, a Phase 3 study of duvelisib in combination with rituximab in patients with previously treated follicular lymphoma (NCT02204982), is expected to start in 2014.

Additionally, a Phase 1 study of duvelisib in patients with advanced blood cancers is ongoing (NCT01476657).
