Verastem Oncology Reports Third Quarter 2018 Financial Results
BOSTON--(BUSINESS WIRE)--Nov 7, 2018--Verastem, Inc. (Nasdaq: VSTM) (Verastem Oncology or the Company), focused on developing and commercializing medicines to improve the survival and quality of life of cancer patients, today reported financial results for the third quarter ended September 30, 2018 and provided an overview of certain corporate developments.
“During the third quarter, we achieved a remarkable milestone with our lead product COPIKTRA™ (duvelisib) receiving its first regulatory approval from the U.S. Food and Drug Administration,” said Robert Forrester, President and Chief Executive Officer of Verastem Oncology. “We were also delighted to have signed an exclusive licensing agreement with CSPC Pharmaceutical Group Limited for the development and commercialization of COPIKTRA for all oncology indications in China, further extending the global reach of our product. This is an exciting time at Verastem Oncology, and we believe this is just the beginning for both COPIKTRA and the Company. It is our goal to unlock the potential of PI3K inhibition, initially as a monotherapy, and through novel combinations to potentially expand its use to broader hematologic and solid tumors.”
“The COPIKTRA launch is well underway and proceeding on track,” said Joseph Lobacki, Executive Vice President and Chief Commercial Officer of Verastem Oncology. “We had the necessary staffing in place and were ready to distribute COPIKTRA on the day of approval. Our commercial field force and medical affairs teams are engaging with physicians, and our contracted specialty pharmacy partners are receiving prescriptions. We are thrilled that within six weeks of the approval date, COPIKTRA has been included in the NCCN guidelines and we’ve secured reimbursement coverage, including the top national plans, for 72% of the U.S. Pharmacy lives. This is an exciting time for Verastem Oncology, and I am proud of the team’s diligent efforts and early progress in the launch.”
Third Quarter 2018 and Recent Highlights:
COPIKTRA (duvelisib)COPIKTRA (duvelisib) Capsules Approved by the FDA – On September 24, 2018, the U.S. Food and Drug Administration (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 confirmatory trials. The commercial launch of COPIKTRA is ongoing. COPIKTRA Added to NCCN Guidelines for CLL/SLL and FL – In early October 2018, following its approval by the FDA, the National Comprehensive Cancer Network® (NCCN) added COPIKTRA to the Clinical Practice Guidelines in Oncology (NCCN Guidelines). Physicians use the NCCN Guidelines as the standard resource for determining the best course of treatment for patients, and 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 – In early October 2018, 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 online in the peer-reviewed journal Blood. The full manuscript titled “The phase 3 DUO trial: duvelisib versus ofatumumab in relapsed and refractory CLL/SLL,” is available at www.bloodjournal.org. Investigator-Sponsored Study Initiated Evaluating COPIKTRA in Combination with Venetoclax – In early September 2018, the first patient was dosed in a multicenter Phase 1/2 clinical trial investigating COPIKTRA in combination with venetoclax, an oral selective inhibitor of BCL-2, in patients with relapsed or refractory CLL/SLL. Preclinical data support this combination, as COPIKTRA has been shown to upregulate BCL-2 transcript and protein expression levels and potentially enhance the ability of venetoclax to induce apoptosis in ex vivo human CLL cells. The primary objectives of the Phase 1 portion of the trial are to determine the maximum tolerated dose and the recommended Phase 2 dose of venetoclax for this combination regimen. The trial is being led by Matthew Davids, M.D., MMSc, Assistant Professor of Medicine, Harvard Medical School, and Associate Director, Center for Chronic Lymphocytic Leukemia, Dana-Farber Cancer Institute. Eight Abstracts Selected for Presentation at the Upcoming American Society of Hematology 2018 Annual Meeting (ASH 2018) – In November 2018, the Company announced that eight abstracts were selected for presentation, including one oral presentation, at ASH 2018 which is being held December 1-4, 2018 in San Diego, CA. The oral presentation will highlight data from the Phase 1 study evaluating COPIKTRA in combination with romidepsin in relapsed or refractory peripheral T-cell lymphoma. Additional poster presentations will showcase preclinical and clinical data reinforcing the potential of COPIKTRA.

Third Quarter 2018 Financial Results
License revenue for the three months ended September 30, 2018 (2018 Quarter) was $15.0 million and was related to an upfront payment pursuant to the license and collaboration agreement executed between Verastem Oncology and CSPC in September 2018. Verastem Oncology had no license revenue during the three months ended September 30, 2017 (2017 Quarter).
Verastem Oncology began commercial sales of COPIKTRA within the United States in September 2018, following receipt of FDA marketing approval on September 24, 2018. For the 2018 Quarter, the Company recorded approximately $508,000 of net product revenue. Verastem Oncology had no product revenue during the 2017 Quarter.
Costs of revenues, excluding amortization of acquired intangible assets (cost of revenues) of approximately $49,000 for the 2018 Quarter, consisted of costs associated with the manufacturing of COPIKTRA, royalties owed to Infinity Pharmaceuticals, Inc. (Infinity) on such sales, and certain period costs. Verastem Oncology expensed the manufacturing costs of COPIKTRA as operating expenses in the periods prior to July 1, 2018. Verastem Oncology had no cost of revenues during the 2017 Quarter.
Research and development expense for the 2018 Quarter was $11.6 million compared to $17.7 million for the 2017 Quarter. The $6.1 million decrease from the 2017 Quarter to the 2018 Quarter was primarily related to a decrease of $6.0 million in license fees related to a one-time milestone payment pursuant to the Infinity license agreement that was recognized in the 2017 Quarter and a decrease of $1.2 million in consulting fees. These decreases were offset by an increase of $1.1 million in personnel related costs, including non-cash stock-based compensation.
Selling, general and administrative expense for the 2018 Quarter was $25.4 million compared to $5.4 million for the 2017 Quarter. The increase of $20.0 million from the 2017 Quarter to the 2018 Quarter primarily resulted from an increase in personnel related costs, including non-cash stock-based compensation, of $9.7 million, primarily related to the hiring and staffing of Verastem Oncology’s sales and commercial teams, an increase in consulting and professional fees of $9.1 million, primarily related to the support of commercial launch preparation activities, and travel and other costs of $1.2 million.
Amortization of acquired intangible assets for the 2018 Quarter of approximately $31,000 was related to the COPIKTRA finite-lived intangible asset which Verastem Oncology recognized and began amortizing in September 2018. There was no amortization of acquired intangible assets in the 2017 Quarter.
Net loss for the 2018 Quarter was $21.7 million, or $0.29 per share, as compared to a net loss of $23.1 million, or $0.61 per share, for 2017 Quarter.
As of September 30, 2018, Verastem Oncology had cash, cash equivalents and investments of $145.6 million compared to $86.7 million of cash, cash equivalents and investments as of December 31, 2017. Cash, cash equivalents and investments for the 2018 Quarter does not include the $145.1 million in net proceeds from the registered direct offering of convertible notes in October 2018.
The number of outstanding common shares as of September 30, 2018 was 73,703,423.
Indications and Usage
Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL)
COPIKTRA is indicated for the treatment of adult patients with relapsed or refractory CLL or SLL after at least two prior therapies.
Follicular Lymphoma (FL)*
COPIKTRA is indicated for the treatment of adult patients with relapsed or refractory FL after at least two prior systemic therapies.

COPIKTRA Clinical Trials
Efficacy in Relapsed or Refractory CLL/SLL
A randomized, multicenter, open-label trial (DUO™; NCT02004522) compared COPIKTRA versus ofatumumab in 319 adult patients with CLL (N = 312) or SLL (N = 7) after at least one prior therapy. The study randomized patients with a 1:1 ratio to receive either COPIKTRA 25mg BID until disease progression or unacceptable toxicity, or ofatumumab for 7 cycles.
The approval of COPIKTRA was based on efficacy and safety analysis of patients with at least 2 prior lines of therapy, where the benefit:risk appeared greater in this more heavily pretreated population compared to the overall trial population.
In this subset (95 randomized to COPIKTRA, 101 to ofatumumab), the median patient age was 69 years (range: 40 to 90 years), 59% were male, and 88% had an ECOG performance status of 0 or 1. Forty-six percent received 2 prior lines of therapy, and 54% received 3 or more prior lines. At baseline, 52% of patients had at least one tumor ≥ 5 cm, and 22% of patients had a documented 17p deletion.
During randomized treatment, the median duration of exposure to COPIKTRA was 13 months (range: 0.2 to 37), with 80% of patients receiving at least 6 months and 52% receiving at least 12 months of COPIKTRA. The median duration of exposure to ofatumumab was 5 months (range: < 0.1 to 6).
Efficacy was based on progression-free survival (PFS) as assessed by an Independent Review Committee (IRC). Other efficacy measures included overall response rate (ORR). Efficacy of COPIKTRA compared to ofatumumab specifically in patients treated with at least two prior therapies is below.
Efficacy in Relapsed or Refractory FL
Efficacy of COPIKTRA in patients with previously treated FL is based on a single-arm, multicenter trial (DYNAMO™; NCT01882803).
In DYNAMO, COPIKTRA 25 mg BID was administered in patients with FL (N = 83) who were refractory to rituximab and to either chemotherapy or radioimmunotherapy. Refractory disease was defined as less than a partial remission or relapse within 6 months after the last dose. The trial excluded patients with Grade 3b FL, large cell transformation, prior allogeneic transplant, and prior exposure to a PI3K inhibitor or to a Bruton’s tyrosine kinase inhibitor.
The median age was 64 years (range: 30 to 82 years), 68% were male, and 37% had bulky disease assessed at baseline (target lesion ≥ 5 cm). Patients had a median of 3 prior lines of therapy (range: 1 to 10), with 94% being refractory to their last therapy and 81% being refractory to 2 or more prior lines of therapy. Most patients (93%) had an ECOG performance status of 0 or 1.
The median duration of exposure to COPIKTRA was 5 months (range: 0.4 to 24), with 41% of patients receiving at least 6 months and 10% receiving at least 12 months of COPIKTRA.
Efficacy was based on overall response rate and duration of response as assessed by an IRC, as shown below.

DRUG INTERACTIONSCYP3A Inducers: Coadministration with a strong CYP3A inducer may reduce COPIKTRA efficacy. Avoid coadministration with strong CYP3A4 inducers. CYP3A Inhibitors: Coadministration with a strong CYP3A inhibitor may increase the risk of COPIKTRA toxicities. Reduce COPIKTRA dose to 15 mg BID when coadministered with a strong CYP3A4 inhibitor. CYP3A Substrates: Coadministration of COPIKTRA with sensitive CYP3A4 substrates may increase the risk of toxicities of these drugs. Consider reducing the dose of the sensitive CYP3A4 substrate and monitor for signs of toxicities of the coadministered sensitive CYP3A substrate.
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 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. 2,3,4 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. 5 For more information on COPIKTRA, please visit www.COPIKTRA.com.
