BOSTON--(BUSINESS WIRE)--Sep. 20, 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 three posters highlighting clinical data for COPIKTRA™ (duvelisib) will be presented at the 18^th Annual International Workshop on Chronic Lymphocytic Leukemia taking place September 20-23, 2019, in Edinburgh, UK. The presented abstracts focus on clinical data from the Phase 3 DUO study including evaluation of COPIKTRA efficacy and safety in heavily pre-treated 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, including those with high-risk factors.

“Many patients with CLL or SLL eventually relapse and are in need of additional therapy options to help control their disease,” said Marco Montillo, M.D., Head, Department of Hematology and Oncology, Niguarda Cancer Center, Niguarda Hospital, Milan, Italy. “In the DUO study, duvelisib monotherapy demonstrated significantly improved clinical outcomes in patients with relapsed refractory disease who had received two or more prior therapies. In the study, the safety profile of duvelisib was generally manageable through dose modifications or interruptions.”

“The data presented at iwCLL this year highlight findings from the Phase 3 DUO study in the labeled indication of relapsed or refractory CLL/SLL after at least 2 prior therapies,” commented Hagop Youssoufian, MSc, M.D., Head of Medical Strategy at Verastem Oncology. “Of note, response rates appeared to be preserved in COPIKTRA-treated patients whose adverse events, occurring on therapy, were effectively managed through dose interruptions or dose reductions. These findings from the study are an important factor in helping physicians navigate the management of adverse events in the clinical setting with the goal of not compromising efficacy.”

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.

PDF copies of these poster presentations will be available here after the meeting.

About Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are cancers that affect lymphocytes and are essentially the same disease, with the only difference being the location where the cancer primarily occurs. When most of the cancer cells are located in the bloodstream and the bone marrow, the disease is referred to as CLL, although the lymph nodes and spleen are often involved. When the cancer cells are located mostly in the lymph nodes, the disease is called SLL. The symptoms of CLL/SLL include a tender, swollen abdomen and feeling full even after eating only a small amount. Other symptoms can include fatigue, shortness of breath, anemia, bruising easily, night sweats, weight loss, and frequent infections. However, many patients with CLL/SLL will live for years without symptoms. There are approximately 200,000 patients in the US affected by CLL/SLL with nearly 20,000 new diagnoses this year alone. While there are therapies currently available, real-world data reveals that a significant number of patients either relapse following treatment, become refractory to current agents, or are unable to tolerate treatment, representing a significant medical need. The potential of additional oral agents, particularly as a monotherapy that can be used in the general community physician’s armamentarium, may hold significant value in the treatment of patients with CLL/SLL.

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 is being investigated in combination with other agents through investigator-sponsored studies.⁴ For more information on COPIKTRA, please visit www.COPIKTRA.com.
