Verastem Oncology Outlines Strategic Priorities for 2019 and Highlights Recent Progress

2018 Highlighted by Approval and Commercial Launch of Lead Asset COPIKTRA™

Entering 2019 with a Strong Balance Sheet to Achieve Corporate Objectives

Company’s Focus in 2019 Will Be on Continued Investigation of Duvelisib in Additional Tumor Types, Including Peripheral T-Cell Lymphoma, Both as a Monotherapy and in Combination with Other Anti-Cancer Agents

BOSTON--(BUSINESS WIRE)--Jan. 3, 2019-- Verastem, Inc. (Nasdaq: VSTM) (Verastem Oncology or the Company), a biopharmaceutical company focused on developing and commercializing medicines to improve the survival and quality of life of cancer patients, today highlighted the company’s recent progress and outlined strategic priorities for 2019.

“2018 was a pivotal year for Verastem Oncology, as the U.S. Food and Drug Administration’s (FDA) approval of COPIKTRA™ and other key accomplishments strongly positioned us to execute on our 2019 corporate priorities that are focused on increasing revenues, initiating additional clinical studies of COPIKTRA and advancing our pipeline,” said Robert Forrester, President and Chief Executive Officer of Verastem Oncology. “We are pleased with the strong vote of confidence we have received in duvelisib, including validating licensing agreements in key Asian markets, recognition of our pivotal Phase 3 data in the medical journal Blood, and more. We are also entering 2019 with a strong balance sheet derived from the successful completion of multiple financing transactions, which we believe provides us with important financial strength to achieve our planned corporate objectives. We look forward to keeping the momentum going, and to sharing ongoing updates on our progress.”

“Since the launch of COPIKTRA, we’ve been encouraged by the positive feedback we are hearing from physicians and other healthcare providers about this important new oral monotherapy within the treatment landscape,” said Joseph Lobacki, Executive Vice President and Chief Commercial Officer of Verastem Oncology. “Following the approval, COPIKTRA was quickly added to the National Comprehensive Cancer Network® (NCCN) guidelines, which has led to its inclusion on formularies and extensive reimbursement coverage, including on the top national health plans, reaching approximately 75% of U.S. Pharmacy lives and providing critical access to treatment for appropriate patients. In 2019, the commercial team will be diligently working to engage with physicians and other health care professionals to focus on ensuring COPIKTRA reaches the patients who need it.”

2018 Accomplishments

  • COPIKTRA (duvelisib) Capsules Approved by the U.S. FDA – On September 24, 2018, the FDA approved COPIKTRA, an oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first approved dual inhibitor of PI3K-delta and PI3K-gamma. COPIKTRA was approved for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (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. The indication in FL is approved under accelerated approval based on overall response rate. Continued approval for this indication is contingent upon verification and description of clinical benefit in a confirmatory trial. The commercial launch of COPIKTRA is ongoing.

    Use of COPIKTRA is associated with a BOXED WARNING for four fatal and/or serious toxicities: infections, diarrhea or colitis, cutaneous reactions, and pneumonitis. Verastem Oncology is implementing an informational Risk Evaluation and Mitigation Strategy to provide appropriate dosing and safety information to better support physicians in managing their patients on COPIKTRA.

    Additionally, use of COPIKTRA is also associated with adverse reactions which may require dose reduction, treatment delay or discontinuation of COPIKTRA.

  • Established a Commercial Franchise in the U.S. – In 2018, the Company established a full commercial infrastructure in the U.S. The sales, market access and medical affairs teams are fully deployed and calling on medical institutions, oncology healthcare professionals and payors in support of the COPIKTRA launch. COPIKTRA product was available at specialty distributors and specialty pharmaceutical providers immediately following approval. Top national health plans are now offering reimbursement coverage and the majority of COPIKTRA sales territories have patients being treated. The Company also successfully launched Verastem Cares™, a comprehensive, personalized program designed to provide information and assistance to patients who have been prescribed COPIKTRA, which is now fully operational nationwide.
  • COPIKTRA Added to NCCN Guidelines for CLL/SLL and FL – The NCCN added COPIKTRA to the Clinical Practice Guidelines in Oncology (NCCN Guidelines), the standard physician resource for determining the appropriate course of treatment for patients. The Company believes these updated guidelines will increase awareness for COPIKTRA and help health care providers make informed decisions for patients battling these difficult to treat advanced cancers.
  • Phase 3 DUO Study Results Published in the Journal Blood – The results of the randomized, multicenter, open-label Phase 3 DUO™ study (NCT02004522), which evaluated COPIKTRA versus ofatumumab in patients with relapsed or refractory CLL/SLL, were published in the peer-reviewed journal Blood (Flinn at al). The publication was accompanied by a review article by Jennifer R. Brown, M.D., Ph.D., Director of the Chronic Lymphocytic Leukemia Center at Dana-Farber Cancer Center, discussing the role of PI3K inhibitors and duvelisib in current CLL therapy. The full manuscript titled “The phase 3 DUO trial: duvelisib versus ofatumumab in relapsed and refractory CLL/SLL,” is available at www.bloodjournal.org.
  • Eight Abstracts Presented at the American Society of Hematology 2018 Annual Meeting (ASH 2018) – The Company presented eight abstracts, including one oral presentation, at ASH 2018 in San Diego. The oral presentation highlighted data from the Phase 1 study evaluating duvelisib in combination with romidepsin in relapsed or refractory peripheral T-cell lymphoma. Additional poster presentations showcased preclinical and clinical data reinforcing the potential of duvelisib.

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 Follicular Lymphoma

Follicular lymphoma (FL) is typically a slow-growing or indolent form of non-Hodgkin lymphoma (NHL) that arises from B-lymphocytes, making it a B-cell lymphoma. This lymphoma subtype accounts for 20 to 30 percent of all NHL cases, with more than 140,000 people in the US with FL and more than 13,000 newly diagnosed patients this year. Common symptoms of FL include enlargement of the lymph nodes in the neck, underarms, abdomen, or groin, as well as fatigue, shortness of breath, night sweats, and weight loss. Often, patients with FL have no obvious symptoms of the disease at diagnosis. Follicular lymphoma is usually not considered to be curable, but more of a chronic disease, with patients living for many years with this form of lymphoma. 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 FL.

About Peripheral T-Cell Lymphoma

Peripheral T-cell lymphoma (PTCL) is a rare, aggressive type of non-Hodgkin lymphoma (NHL) that develops in mature white blood cells called “T cells” and “natural killer (NK) cells”2 which circulate with the lymphatic system.3 PTCL accounts for between 10-15% of all non-Hodgkin lymphomas (NHLs) and generally affects people aged 60 years and older.2 Although there are many different subtypes of peripheral T-cell lymphoma, they often present in a similar way, with widespread, enlarged, painless lymph nodes in the neck, armpit or groin.3 There is currently no established standard of care for patients with relapsed or refractory disease.2

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.4,5,6 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.7 For more information on COPIKTRA, please visit www.COPIKTRA.com. Information about duvelisib clinical trials can be found on www.clinicaltrials.gov.

About Defactinib

Defactinib is an investigational inhibitor of focal adhesion kinase (FAK), a non-receptor tyrosine kinase that mediates oncogenic signaling in response to cellular adhesion and growth factors.8 Based on the multi-faceted roles of FAK, defactinib is used to treat cancer through modulation of the tumor microenvironment and enhancement of anti-tumor immunity.9,10 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 cancer, ovarian cancer, non-small cell lung cancer (NSCLC), and mesothelioma. These studies are combination clinical trials with pembrolizumab and avelumab from Merck & Co. and Pfizer/Merck KGaA, respectively.11,12,13 Information about these and additional clinical trials evaluating the safety and efficacy of defactinib can be found on www.clinicaltrials.gov.
