Verastem Oncology Announces COPIKTRA™ (Duvelisib) Presentations at the Lymphoma & Myeloma 2019 International Congress

BOSTON--(BUSINESS WIRE)--Oct. 23, 2019-- Verastem, Inc. (Nasdaq:VSTM) (Verastem Oncology or the Company), a biopharmaceutical company focused on developing and commercializing medicines seeking to improve the survival and quality of life of cancer patients, today announced that five posters highlighting clinical data for COPIKTRA™ (duvelisib) will be presented at the Lymphoma & Myeloma 2019 International Congress taking place October 23-26, 2019, in New York City. The presented abstracts focus on clinical data from the Phase 3 DUO study, including evaluation of COPIKTRA efficacy and safety in high-risk patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), dose modification data and results from a post-hoc analysis evaluating the effect of COPIKTRA on lymphocytosis in patients. Other presented data include the characterization of duvelisib in patients with refractory Marginal Zone Lymphoma from the Phase 2 DYNAMO study, and an update on the safety profile and management of adverse events in heavily pre-treated patients with advanced hematological malignancies.

“Findings from the DUO study demonstrated that patients taking duvelisib who have received two or more prior therapies experienced improved clinical outcomes and a manageable safety profile,” states Matthew S. Davids, MD, Associate Director, Center for Chronic Lymphocytic Leukemia at Dana-Farber Cancer Institute. “These results with duvelisib are important for this patient population, which is in need of targeted therapies to control their disease.”

“The data presented at this year’s Lymphoma & Myeloma Congress reflect the utility of duvelisib in patients with relapsed or refractory CLL/SLL after at least two prior therapies, including in patients with advanced disease or at high-risk of recurrence,” commented Hagop Youssoufian, MSc, M.D., Head of Medical Strategy at Verastem Oncology. “Further, the research supports the approach to management of adverse events through dose interruptions or dose reductions without an impact on the patient’s response, which could allow patients who are benefitting to stay on therapy longer.”

COPIKTRA, a targeted oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first approved dual inhibitor of PI3K-delta and PI3K-gamma, received approval as monotherapy from the U.S. Food and Drug Administration (FDA) in September 2018 for the treatment of patients with relapsed or refractory CLL/SLL after at least two prior therapies. COPIKTRA also received accelerated approval for the treatment of adult patients with relapsed or refractory follicular lymphoma (FL) after at least two prior systemic therapies. Continued approval in FL may be contingent upon verification and description of clinical benefit in confirmatory trials.

See full Prescribing Information for complete boxed warning
  • Fatal and/or serious infections occurred in 31% (4% fatal) of COPIKTRA-treated patients. Monitor for signs and symptoms of infection. Withhold COPIKTRA if infection is suspected.
  • Fatal and/or serious diarrhea or colitis occurred in 18% (<1% fatal) of COPIKTRA-treated patients. Monitor for the development of severe diarrhea or colitis. Withhold COPIKTRA.

About COPIKTRA™ (duvelisib)

COPIKTRA is an oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first approved dual inhibitor of PI3K-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant B-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 COPIKTRA is indicated for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) after at least two prior therapies and relapsed or refractory follicular lymphoma (FL) after at least two prior systemic therapies. COPIKTRA is also being developed by Verastem Oncology for the treatment of peripheral T-cell lymphoma (PTCL), for which it has received Fast Track status and Orphan Drug Designation, and is being investigated in combination with other agents through investigator-sponsored studies.4 For more information on COPIKTRA, please visit www.COPIKTRA.com.
