BOSTON--(BUSINESS WIRE)--Nov. 7, 2017-- Verastem, Inc. (NASDAQ:VSTM), focused on discovering and developing drugs to improve the survival and quality of life of cancer patients, today reported financial results for the third quarter ended September 30, 2017 and provided an overview of certain corporate developments and plans.

“The third quarter was a pivotal time for Verastem with the announcement of positive top-line data from the pivotal Phase 3 DUO™ study evaluating oral duvelisib monotherapy in patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL),” said Robert Forrester, President and Chief Executive Officer of Verastem. “The DUO study met its primary endpoint, with progression-free survival (PFS) significantly favoring duvelisib monotherapy over ofatumumab, an approved standard of care treatment for patients with CLL/SLL. We recently met with the U.S. Food and Drug Administration (FDA), and based on the meeting and written feedback, we intend to submit, during the first quarter of 2018, 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). The NDA will be based on a comprehensive clinical data package, including the Phase 3 DUO and Phase 2 DYNAMO studies evaluating duvelisib in patients with advanced hematologic malignancies.”

Mr. Forrester concluded, “At the upcoming American Society of Hematology 2017 Annual Meeting (ASH 2017), we will be presenting data from multiple studies, including the detailed positive results from the Phase 3 DUO study, which were selected for an oral presentation.”

Third Quarter 2017 and Recent Highlights:

Duvelisib

• Announced Regulatory Strategy for Duvelisib NDA – Verastem recently announced that a meeting was held with the U.S. Food and Drug Administration (FDA) regarding the regulatory path for duvelisib. Based on the meeting with, and written feedback from the FDA, 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 FL. Along with the clinical data from the DUO study, the duvelisib NDA submission will also contain the favorable results from the Phase 2 DYNAMO™ study in double-refractory indolent non-Hodgkin’s lymphoma (iNHL), which also achieved its primary endpoint with an ORR of 46% (p<0.0001). In the subset of patients enrolled in the DYNAMO study with double-refractory FL (n=83), duvelisib demonstrated an ORR of 41%. The Company expects to submit the duvelisib NDA during the first quarter of 2018.
• Reported Positive Top-line Data from the Pivotal Phase 3 DUO Study in Relapsed or Refractory CLL/SLL – In September 2017, Verastem reported that the Phase 3 DUO study met its primary endpoint with oral duvelisib monotherapy demonstrating superiority over ofatumumab for PFS in patients with CLL/SLL. In this study, duvelisib achieved a statistically significant improvement in median PFS of 13.3 months, compared to 9.9 months for ofatumumab with a hazard ratio of 0.52 (p<0.0001), representing a 48% reduction in the risk of progression or death. Duvelisib monotherapy had a manageable safety profile, with results from this study consistent with the well-characterized safety profile of duvelisib monotherapy in patients with advanced hematologic malignancies.
• Expanded Duvelisib Program to Include Peripheral T-Cell Lymphoma – In September 2017, Verastem announced the expansion of its duvelisib development program to include targeting the treatment of patients with Peripheral T-Cell Lymphoma (PTCL). Duvelisib was granted Fast Track designation by the FDA for the treatment of patients with PTCL who have received at least one prior therapy. Development of duvelisib in PTCL is supported by encouraging Phase 1 clinical data which demonstrated a 50% investigator-assessed overall response rate in 16 heavily pre-treated patients with relapsed or refractory PTCL, including 3 (19%) complete responses and 5 (31%) partial responses. Verastem intends to initiate an open-label, multicenter, Phase 2 clinical trial evaluating the efficacy and safety of duvelisib in patients with relapsed or refractory PTCL by the end of 2017.
• Clinical Data from Pivotal Phase 3 DUO Study Selected for Oral Presentation at ASH 2017 – Verastem recently announced that an abstract highlighting clinical data from the Phase 3 DUO study was selected for oral presentation at ASH 2017. The presentation, titled “Results from the Phase 3 DUO Trial: A Randomized Comparison of Duvelisib Vs Ofatumumab in Patients with Relapsed/Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma,” will be presented by principal investigator, Ian Flinn, M.D., Ph.D., Director of the Blood Cancer Research Program at Sarah Cannon Research Institute, on Sunday, December 10, 2017 at 4:30pm ET at the Georgia World Congress Center, in Building B, Level 5, Murphy BR 3-4.
• Additional Duvelisib Abstracts Selected for Presentation at ASH 2017 – Along with the Phase 3 DUO results, two additional duvelisib abstracts were selected for presentation at ASH 2017. The abstract, titled “In Vitro, In Vivo, and Parallel Phase I Evidence Support the Safety and Activity of Duvelisib, a PI3K-δ,γ Inhibitor, in Combination with Romidepsin or Bortezomib in Relapsed/Refractory T-Cell Lymphoma,” will be given as an oral presentation by Steven Horowitz, M.D., Memorial Sloan Kettering Cancer Center, on Monday, December 11, 2017 at 5:00pm ET at the Georgia World Congress Center, in Building A, Level 4, Marcus Auditorium. The abstract, titled “The Dual PI3K-δ,γ Inhibitor Duvelisib Stimulates Anti-Tumor Immunity and Enhances Efficacy of Immune Checkpoint and Co-Stimulatory Antibodies in a B Cell Lymphoma Model,” will be given as a poster presentation by Jonathan Pachter, Ph.D., Chief Scientific Officer of Verastem, on Saturday, December 9, 2017 from 5:30-7:30pm ET at the Georgia World Congress Center, in Building A, Level 1, Hall A2.
• Verastem to Host Key Opinion Leader Event at ASH 2017 – On Sunday, December 10, 2017, Verastem will host an investor and analyst reception, which will feature a moderated panel discussion/Q&A including Ian Flinn, MD, Director of the Blood Cancer Research Program at Sarah Cannon Cancer Center in Nashville, TN.

About Duvelisib

Duvelisib is an 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 clinical 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 is preparing to submit a New Drug Application to the U.S. Food and Drug Administration for the treatment of patients with relapsed or refractory CLL/SLL and patients with follicular lymphoma (FL) whose disease has progressed and are refractory to rituximab and to either chemotherapy or radioimmunotherapy. 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.

About Defactinib

Defactinib is an investigational inhibitor of FAK, a non-receptor tyrosine kinase that mediates oncogenic signaling in response to cellular adhesion and growth factors.⁷ Based on the multi-faceted roles of FAK, defactinib is used to treat cancer through modulation of the tumor microenvironment, enhancement of anti-tumor immunity, and reduction of cancer stem cells.^8,9 Defactinib is currently being evaluated in three separate clinical collaborations in combination with immunotherapeutic agents for the treatment of several different cancer types including pancreatic, ovarian, non-small cell lung cancer, and mesothelioma. These studies are combination clinical trials with pembrolizumab and avelumab from Merck & Co. and Pfizer/Merck KGaA, respectively.^10,11,12 Information about these and additional clinical trials evaluating the safety and efficacy of defactinib can be found on www.clinicaltrials.gov.
