Verastem to Present Results from Pivotal Phase 3 DUO Study in Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma at a Research and Development Event at ASH 2017

Event and Live Webcast to be Held on December 10th at 8:15 PM ET in Atlanta

BOSTON--(BUSINESS WIRE)--Dec. 5, 2017-- Verastem, Inc. (NASDAQ:VSTM), focused on discovering and developing drugs to improve the survival and quality of life of cancer patients, will present clinical data from the Phase 3 DUO study evaluating the efficacy and safety of duvelisib in patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) at a Research and Development reception at the American Society of Hematology (ASH) 2017 Annual Meeting. The event will take place on Sunday, December 10, 2017 in Atlanta.

The event, which follows the oral presentation of the DUO data results at ASH, will feature a slide presentation and moderated panel discussion with recognized experts in the treatment of hematologic malignancies, including CLL/SLL, and a live Q&A session. Speakers will include Ian Flinn, MD, PhD, Sarah Cannon Research Institute, who will present results from the Phase 3 DUO study, and Steven Horwitz, MD, Memorial Sloan Kettering Cancer Center, who will provide an update on duvelisib for the treatment of Peripheral T-Cell Lymphoma (PTCL). In addition, Lori Kunkel, MD, Verastem Clinical and Scientific Advisory Board, and Steven Bloom, Verastem Chief Strategy Officer, will participate in the discussion panel and Q&A session, which will be moderated by Robert Forrester, Verastem President and Chief Executive Officer.

Duvelisib is Verastem’s first in class oral dual inhibitor of phosphoinositide-3-kinase (PI3K)-delta and PI3K-gamma which is currently being developed for the treatment of CLL/SLL, peripheral T cell lymphoma (PTCL), and other hematologic malignancies.

About Duvelisib

Duvelisib is a first-in-class investigational, dual inhibitor of phosphoinositide 3-kinase (PI3K)-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant B-cells and T-cells. PI3K signaling may lead to the proliferation of malignant B-cells and is thought to play a role in the formation and maintenance of the supportive tumor microenvironment.1,2,3 Duvelisib is currently being evaluated in late- and mid-stage extension trials, including DUO™, a randomized, Phase 3 monotherapy study in patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL),4 and DYNAMO™, a single-arm, Phase 2 monotherapy study in patients with refractory indolent non-Hodgkin lymphoma (iNHL).5 Both DUO and DYNAMO achieved their primary endpoints and Verastem intends to submit a New Drug Application (NDA) requesting the full approval of duvelisib for the treatment of patients with relapsed or refractory CLL/SLL, and accelerated approval for the treatment of patients with relapsed or refractory follicular lymphoma (FL). Duvelisib is also being developed by Verastem for the treatment of peripheral T-cell lymphoma (PTCL), and is being investigated in combination with other agents through investigator-sponsored studies.6 Information about duvelisib clinical trials can be found on www.clinicaltrials.gov.
