"Recent research shows that FAK inhibitors could be beneficial in combination with immuno-oncology agents.1 We are excited to be working with Merck KGaA, Darmstadt, Germany, and Pfizer to build upon the early clinical signals observed in patients with ovarian cancer receiving combination therapy with VS-6063"

DARMSTADT, Germany, NEW YORK& BOSTON--(BUSINESS WIRE)--Merck KGaA, Darmstadt, Germany, Pfizer and Verastem announced today that they have entered into an agreement to evaluate avelumab*, an investigational fully human anti-PD-L1 IgG1 monoclonal antibody, in combination with Verastem’s VS-6063**, an investigational focal adhesion kinase (FAK) inhibitor, in patients with advanced ovarian cancer. Avelumab is currently under clinical investigation across a broad range of tumor types. The Phase I/Ib clinical trial is expected to begin in the second half of 2016. Financial terms of the agreement have not been disclosed.

“Combination strategies in immuno-oncology offer significant promise for patients in need. Through our collaboration with Verastem, we hope to accelerate our understanding of avelumab and its potential as a combination therapy with FAK inhibition for patients fighting ovarian cancer,” said Dr. Alise Reicin, Head of Global Clinical Development at Merck KGaA, Darmstadt, Germany’s biopharma business, which in the US and Canada operates as EMD Serono.

“Through this collaboration, we hope to advance our understanding of how FAK inhibition may complement our development program for avelumab, with the ultimate goal of potentially achieving better outcomes for women with ovarian cancer,” said Chris Boshoff, Vice President and Head of Early Development, Translational and Immuno-Oncology at Pfizer Oncology.

“Recent research shows that FAK inhibitors could be beneficial in combination with immuno-oncology agents.1 We are excited to be working with Merck KGaA, Darmstadt, Germany, and Pfizer to build upon the early clinical signals observed in patients with ovarian cancer receiving combination therapy with VS-6063,” said Robert Forrester, Verastem President and Chief Executive Officer.

FAK is a protein which is often overproduced in tumors, enabling cancer cells to evade attack by the immune system. As reported in the September 24, 2015, edition of Cell, pre-clinical research shows that FAK inhibition can modulate the balance of immune cells in the tumor, increasing the presence of cytotoxic T cells in the tumor and decreasing the presence of immunosuppressive T regulatory cells.1

*Avelumab is the proposed International Non-proprietary Name for the anti-PD-L1 IgG1 monoclonal antibody (MSB0010718C). Avelumab is under clinical investigation and has not been proven to be safe and effective. There is no guarantee any product will be approved in the sought-after indication by any health authority worldwide.

**VS-6063 (defactinib) is under clinical investigation and has not be proven to be safe and effective. There is no guarantee any product will be be approved in the sought-after indication by any health authority worldwide.

About Ovarian Cancer

Globally, ovarian cancer is the seventh most common cancer in women.2 Annually, nearly 239,000 cases are diagnosed worldwide.3Ovarian cancer may be difficult to diagnose, as symptoms may appear only in the later stages, when the disease has spread beyond the ovaries.3 Outcomes for women with ovarian cancer are generally poor due to most patients presenting with advanced disease.4The 5-year prevalence of women globally living with ovarian cancer is 22.6 per 100,000.3 Current treatment options for epithelial ovarian cancer may include surgery, radiotherapy, chemotherapy and targeted therapies.5 Women who are unable to undergo treatment with platinum-based chemotherapy, due to resistance or refractory disease, currently have very limited treatment options. Platinum-resistant ovarian cancer is defined as ovarian cancer that recurs within six months of completing primary chemotherapy with a platinum-based medication.6 Platinum-refractory ovarian cancer is defined as ovarian cancer that progresses during treatment with a platinum-based chemotherapy regimen.6 There is still a clear unmet need in ovarian cancer in relation to general disease awareness,3improving initial investigations in primary and secondary care and novel therapies with demonstrable efficacy.7

About Avelumab

Avelumab (also known as MSB0010718C) is an investigational fully human anti-PD-L1 IgG1 monoclonal antibody. By inhibiting PD-L1 interactions, avelumab is thought to enable the activation of T-cells and the adaptive immune system. By retaining a native Fc-region, avelumab is thought to potentially engage the innate immune system and induce antibody-dependent cell-mediated cytotoxicity (ADCC). In November 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.
