- Poster Presentation to Include Updated Data from Ongoing Phase 1 Study of IPI-549 in Patients with Advanced Solid Tumors -

CAMBRIDGE, Mass., March 2, 2017 /PRNewswire/ -- Infinity Pharmaceuticals, Inc. (NASDAQ: INFI) today announced that

new Phase 1 data for IPI-549, an orally administered immuno-oncology development candidate that selectively inhibits phosphoinositide-3-kinase gamma (PI3K-gamma), will be presented in a clinical trial poster session at the American Association for Cancer Research (AACR) Annual Meeting 2017 taking place in Washington, D.C. April 1 – 5. A Phase 1 clinical study is ongoing to explore the safety and activity of IPI-549 both as a monotherapy and in combination with Opdivo® (nivolumab), a PD-1 immune checkpoint inhibitor, in patients with advanced solid tumors. IPI-549 is believed to be the only PI3K-gamma inhibitor in clinical development.

Details of the presentation are as follows:Poster presentation time:  Tuesday, April 4, 2017, 8:00 a.m. – 12:00 p.m. ET Title: IPI-549-01 - A Phase 1/1b, First-in-Human Study of IPI-549, a PI3K-Gamma Inhibitor, as Monotherapy and in Combination with Nivolumab in Patients with Advanced Solid TumorsAbstract number: CT089Lead author: Jedd Wolchok, M.D., Ph.D., Chief of the Melanoma and Immunotherapeutics Service at Memorial Sloan Kettering Cancer Center (MSK), as well as Associate Director of the Ludwig Center for Cancer Immunotherapy and Director of the Parker Institute for Cancer Immunotherapy, both at MSKLocation: Convention Center, Halls A-C, Poster Section 33

About the IPI-549 and the Ongoing Phase 1 Study IPI-549 is an investigational, orally administered immuno-oncology development candidate that selectively inhibits PI3K-gamma. In preclinical studies, IPI-549 increases antitumor immunity by targeting tumor-associated myeloid cells and overcomes immune checkpoint blockade resistance in preclinical tumor models.1,2 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.

A Phase 1 study of IPI-549 in patients with advanced solid tumors is ongoing to explore the activity, safety, tolerability, pharmacokinetics and pharmacodynamics of IPI-549 as a monotherapy and in combination with Opdivo® in patients with advanced solid tumors.3 The study includes monotherapy and combination dose-escalation phases, in addition to a monotherapy expansion cohort and combination expansion cohorts. Overall, the study is expected to enroll approximately 175 patients.

The expansion cohorts evaluating IPI-549 plus Opdivo will include patients with non-small cell lung cancer (NSCLC), melanoma and squamous cell carcinoma of the head and neck (SCCHN). There is a great need for additional treatment options for the growing number of patients living with these types of cancers, which account for more than 17 percent of all new cancer cases in the U.S.4,5 Additionally, patients enrolled in the combination expansion cohorts represent a difficult-to-treat population, as they must have demonstrated initial resistance or subsequently develop resistance to a PD-1 or PD-L1 therapy immediately prior to enrolling in the study.  

IPI-549 is an investigational compound and its safety and efficacy has not been evaluated by the U.S. Food and Drug Administration or any other health authority.
