In a separate press release issued today, Infinity reported preclinical data in models of aggressive non-Hodgkin lymphoma (aNHL) and T-cell acute lymphoblastic leukemia (T-ALL). Additionally, early Phase 1 clinical data in patients with advanced aNHL were reported, with reductions in adenopathy (decrease in the size of lymph nodes) observed in patients with diffuse large B-cell lymphoma (DLBCL) and Richter transformation, as well as a partial response in a patient with transformed follicular lymphoma.
These posters, presented at the 55th Annual Meeting of ASH, are available in the Publications Archive on Infinity’s website http://www.infi.com/product-candidates-publications.asp.
About the Development of IPI-145 for the Treatment of Blood Cancers
Infinity is developing IPI-145, 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 PI3K-delta,gamma isoforms are preferentially expressed in leukocytes (white blood cells), where they have distinct and mostly non-overlapping roles in immune cell development and function. Targeting PI3K-delta and PI3K-gamma may provide multiple opportunities to develop differentiated therapies for the treatment of hematologic malignancies as well as inflammatory diseases.Infinity has launched DUETTS, a worldwide investigation of IPI-145 in blood cancers. As part of the DUETTS program, Infinity is currently enrolling patients in DYNAMO, a Phase 2 monotherapy study designed to evaluate the safety and efficacy of IPI-145 in patients with refractory indolent non-Hodgkin lymphoma (iNHL) (ClinicalTrials.gov Identifier NCT01882803), and DUO, a Phase 3 monotherapy study designed to evaluate the safety and efficacy of IPI-145 in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) (ClinicalTrials.gov Identifier NCT02004522). An investigator-sponsored Phase 1b, open-label study of IPI-145 in patients with B-cell NHL, CLL and T-cell lymphoma in combination with rituximab (a monoclonal antibody therapy), bendamustine (a chemotherapy) or both rituximab and bendamustine is also open for enrollment (NCT01871675).
