"Over the past couple of years, exciting data have emerged from several research groups demonstrating the importance of FAK inhibition in the immuno-oncology arsenal," said Dr. Jonathan Pachter, Verastem Head of Research. "Our presentation next week at Immunotherapy World 2016 will provide an overview of preclinical research to date demonstrating how FAK inhibition increases influx of cytotoxic T cells into tumors while reducing immuno-suppressive and stromal density barriers to anti-tumor immune attack. This creates a more favorable tumor microenvironment for the antitumor effects of immune checkpoint inhibitors and potentially other immunotherapies. Preclinical models have demonstrated extended survival with the combination of our FAK inhibitor with anti-PD-1 therapy, and we plan to test this hypothesis clinically in several tumor types and combinations in 2016. The first of such clinical trials was recently started at Washington University of Saint Louis in patients with advanced pancreatic cancer."

The Washington University of Saint Louis clinical trial is evaluating Verastem’s focal adhesion kinase (FAK) inhibitor VS-6063 in combination with Merck’s PD-1 inhibitor pembrolizumab and gemcitabine/Nab-paclitaxel in patients with pancreatic cancer. This clinical study is supported by a growing body of preclinical research suggesting that focal adhesion kinase (FAK) inhibition, when combined with PD-1 inhibitors, increases the anti-tumor activity of these immunotherapeutic agents. As published in the journal Cell (24 Sept 2015), FAK inhibition has been shown to increase cytotoxic (CD8+) T cells in tumors and decrease immunosuppressive T regulatory cells leading to full tumor regression. This is the first of several combination clinical trials Verastem expects to initiate this year.

Details for the Immunotherapy World 2016 events are as follows:

About Focal Adhesion Kinase

Focal Adhesion Kinase (FAK) is a non-receptor tyrosine kinase encoded by the PTK-2 gene that is involved in cellular adhesion and metastatic capability. VS-6063 (defactinib) and VS-4718 are orally available compounds designed to target cancer stem cells through the potent inhibition of FAK. Cancer stem cells are an underlying cause of tumor resistance to chemotherapy, recurrence and ultimate disease progression. Research has demonstrated that FAK activity is critical for the growth and survival of cancer stem cells. VS-6063 and VS-4718 are currently being studied in multiple clinical trials for their ability to improve patient survival through the targeting of cancer stem cells, potentiation of an immune response against cancer cells and reduction of the stromal density encapsulating a tumor.

A mimotope is a small molecule, often a peptide, which mirrors the structure of an epitope, the specific target to which an antibody binds. Because of this property it induces an antibody response similar to the one elicited by the epitope. Mimotope vaccines can trigger B-cells to produce antibodies cross reactive with the native epitope they recognise.

Imugene will own the Intellectual Property in the mimotope vaccines generated under the partnership as well as the right to use the platform to generate additional mimotope vaccines independent of the University. In addition, Imugene is entitled to access additional mimotope vaccines of interest to it.

Professor Dr Ursula Wiedermann, Chief Scientific Officer of Imugene said "This is particularly exciting since mimotope cancer vaccines are set to be part of the next wave of the immunooncology revolution in cancer therapy. This project will position Imugene competitively in immuno-oncology research, expanding its pipeline and will efficiently transform Imugene into a multi-asset biopharmaceutical company." Executive Chairman Mr Paul Hopper said "Imugene has secured a strategic license and entered into a research collaboration with the Medical University of Vienna which greatly extends the company’s oncology franchise and pipeline. Thanks largely to the strong relationships being developed between Imugene and the Medical University of Vienna and Prof. Wiedermann on the HER-Vaxx program, we are now able to actively participate in this paradigm shifting research underway at the Medical University of Vienna and systematically develop cutting edge drug candidates. Work has commenced and we look forward with anticipation to developments in this area. Whilst being cautious about the early stage of the program, what is particularly exciting is the potential to discover mimotopes for vaccination against cancer targets offering the opportunity to further develop the current treatment concepts of best selling drugs." "This collaboration gives Imugene the opportunity to build on our unique and promising pipeline of immuno-oncology B-cell vaccines. This innovative approach to cancer therapy will ensure

The FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the FOCUS Trial) will evaluate the safety, efficacy and pharmacokinetic profile of Melphalan/HDS versus best alternative care in 240 patients with OM. The primary endpoint is a comparison of overall survival between the two study arms; secondary and exploratory endpoints include progression-free survival, overall response rate and quality of life measures. The FOCUS Trial is being conducted under a Special Protocol Assessment (SPA) with the U.S. Food and Drug Administration (FDA), and per the SPA is the only Phase 3 trial required for submission of a New Drug Application.

In the trial’s treatment phase, patients randomized to the Melphalan/HDS arm will receive up to six treatments at intervals of six to eight weeks for up to 12 months. Tumor response will be assessed in both study arms every 12 weeks until evidence of hepatic disease progression. For patients progressing to the follow-up phase, disease assessment scans will continue every 12 weeks for up to two years. The FOCUS Trial will be conducted at leading cancer centers in the United States and Europe.

Under the terms of the SPA, at least 50% of patients will be treated in the U.S. The Moffitt Cancer Center in Tampa, Fla. has been activated as a participating center and Jonathan Zager, M.D., FACS, Professor of Surgery in the Cutaneous Oncology and Sarcoma Departments and a Senior Member at Moffitt Cancer Center, is serving as the trial’s principal investigator.

"I am particularly pleased to serve as principal investigator in this very promising study as I have treated patients with Melphalan/HDS through both formal clinical research and compassionate use since 2007," said Dr. Zager. "Our experience at Moffitt with Melphalan/HDS in patients with hepatic dominant ocular melanoma has shown significant potential. We are pleased to be taking a leadership role in the FOCUS Trial, and look forward to verifying the potential for Melphalan/HDS in this life-threatening cancer with no effective treatment options."

"We believe the FOCUS Trial puts us on the fastest path to a regulatory submission in the U.S. and initiation of this trial is a landmark event for Delcath," said Jennifer K. Simpson, Ph.D., MSN, CRNP, President and Chief Executive Officer of Delcath. "We are delighted to be working with the Moffitt Cancer Center and look forward to activating a number of other premier cancer centers as clinical sites in the coming months. Our goal is to have an interim analysis, which we expect to occur in the second half of 2017. We look forward to bringing this potentially life-saving therapy to patients suffering with hepatic ocular melanoma."

"The FOCUS Trial will utilize an improved Melphalan/HDS product/procedure that addresses safety issues raised in our previous Phase 3 study. Based on our commercial experience in Europe, and the bolus of clinical data recently presented and published, we are optimistic that the FOCUS Trial will demonstrate a compelling benefit/risk profile and that the study’s objectives will be met," added Dr. Simpson.
