Under the terms of the agreement, Exelixis will partner with StemSynergy to conduct preclinical and clinical studies with compounds from StemSynergy’s CK1α Activator Program. Exelixis will pay StemSynergy an upfront payment of $3M and up to $3.5M in initial research and development funding. StemSynergy will be eligible for a variety of milestones for the first product to emerge from the collaboration, including preclinical and clinical development and regulatory milestone payments, commercial milestones, as well as single-digit royalties on worldwide sales. Exelixis will be solely responsible for the commercialization of products that arise from the collaboration.

"Supported by revenues from its commercial products and collaborations, Exelixis is on a growth trajectory and now actively focused on augmenting our pipeline both through targeted business development and internal drug discovery activities," said Peter Lamb, Ph.D., Executive Vice President, Discovery Research and Chief Scientific Officer of Exelixis. "CK1α activation is an underexplored and intriguing mechanism for addressing the Wnt/β-catenin axis, a major pathway deregulated in multiple cancers. We look forward to working with StemSynergy to advance this compelling program as we build the next generation of Exelixis medicines."

The CK1α Activator Program is representative of StemSynergy’s focus on treating cancer by targeting developmental processes that are reactivated in cancer cells. The Wnt signaling pathway is a prominent example of this process: the pathway plays an important role in embryonic development, but can support oncogenic processes when deregulated in adult tissues. Activation of β-catenin, a key downstream component of the pathway, is increased in multiple tumors, including a majority of colorectal cancers, where mutations in the APC gene that result in beta-catenin stabilization are prevalent. CK1α Activator Program compounds have been shown to induce degradation of β-catenin and pygopus, another member of the pathway, in preclinical CRC models, and to inhibit the growth of tumors. Importantly, their GI-sparing qualities may help overcome limitations of other approaches targeting the Wnt pathway.

"StemSynergy is developing compounds that can specifically address developmental pathways reactivated in cancer cells to potentially deliver greater benefit to patients," said Anthony J. Capobianco, Ph.D., President and Co-Founder of StemSynergy. "Our CK1α Activator Program has been supported in part by the National Cancer Institute through the SBIR program. With deep drug discovery and development expertise and a proven track record of successfully bringing medicines to market, Exelixis is a natural partner for our CK1α Activator Program as it advances. We look forward to collaborating with the experienced Exelixis team to move the program forward."

Additionally, Mirati is eligible to receive up to $123 million of additional payments based upon the achievement of certain development, regulatory and sales milestones as well as significant royalties on future sales of sitravatinib in the licensed territory.

About Sitravatinib

Sitravatinib (MGCD-0516) is a spectrum-selective kinase inhibitor which potently inhibits receptor tyrosine kinases (RTKs) including RET, TAM family receptors (TYRO3, Axl, MER), and split family receptors (VEGFR2, KIT). Sitravatinib is being evaluated as a single agent in a Phase 1b expansion trial enrolling patients that harbor RET, CHR4Q12, and CBL genetic alterations in NSCLC and other tumors.

As an immuno-oncology agent, sitravatinib is being tested in combination with anti PD-1 checkpoint inhibitor nivolumab in NSCLC patients who have progressed after prior treatment with a checkpoint inhibitor. Sitravatinib’s potent inhibition of TAM and split family receptors may help overcome resistance to checkpoint inhibitor therapy through enhancement of dendric cell-dependent antigen presentation, targeted depletion of immunosuppressive T regulatory cells and myeloid-derived suppressor cells, and conversion of tumor associated macrophages to an immune-enhancing Type I composition, in the tumor microenvironment.

About Tislelizumab (BGB-A317)

Tislelizumab is an investigational humanized monoclonal antibody that belongs to a class of immuno-oncology agents known as immune checkpoint inhibitors. It is designed to bind to PD-1, a cell surface receptor that plays an important role in downregulating the immune system by preventing the activation of T-cells. Tislelizumab has demonstrated high affinity and specificity for PD-1. It is differentiated from the currently approved PD-1 antibodies in an engineered Fc region, which is believed to minimize potentially negative interactions with other immune cells. Tislelizumab is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers. BeiGene and Celgene Corporation have a global strategic collaboration for tislelizumab for solid tumors outside of Asia (except Japan).

About Chemotherapy-Induced Nausea and Vomiting (CINV)

While chemotherapy is one of the most effective and commonly used therapies to help patients fight cancer, it is accompanied by debilitating side effects, including varying degrees of nausea and vomiting, often attributed as a leading cause of premature discontinuation of cancer treatment. The goal of antiemetic therapy is to prevent CINV in both the acute phase (0 – 24 hours after chemotherapy) and delayed phase (24 – 120 hours after chemotherapy). The National Comprehensive Cancer Network (NCCN) and the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) have categorized chemotherapy regimens based on the degree to which they cause nausea and vomiting: low emetogenic chemotherapy (LEC); moderately emetogenic chemotherapy (MEC); and highly emetogenic chemotherapy (HEC).
