Kura Oncology Receives FDA Clearance to Proceed with Clinical Trial for ERK Inhibitor KO-947 and Nominates KO-539 as Development Candidate for Menin-MLL Inhibitor Program

On January 4, 2016 Kura Oncology, Inc. (NASDAQ:KURA), a clinical stage biopharmaceutical company, reported that the U.S. Food and Drug Administration (FDA) accepted the company’s Investigational New Drug (IND) application to begin Phase 1 clinical testing of KO-947, its small molecule inhibitor of extracellular-signal-regulated kinases 1 and 2 (ERK1/2) as a treatment for cancers in which the mitogen activated protein kinase (MAPK) pathway is dysregulated (Press release, Kura Oncology, JAN 4, 2017, View Source [SID1234517257]). Additionally, Kura announced nomination of KO-539, an orally-available small molecule inhibitor of the menin-MLL interaction, as a development candidate for the treatment of mixed lineage leukemias, a genetically-defined subset of the two most common forms of acute leukemia, acute myeloid leukemia and acute lymphoblastic leukemia.

"We are delighted to reach these important milestones in the development of our pipeline programs. KO-947, our ERK inhibitor, has shown compelling and differentiated anti-tumor activity in preclinical models of cancers in which the MAPK pathway is dysregulated, and we look forward to advancing it into human clinical testing," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "We are also pleased to nominate KO-539, an inhibitor of the menin-MLL interaction, as a development candidate, which we are advancing as a potential treatment for patients with particularly aggressive forms of leukemia. Along with the progress we have made on tipifarnib, our lead program, these achievements are a testament to our team’s ability to execute on our stated goal of simultaneously advancing multiple programs aimed at addressing the urgent needs of cancer patients facing a poor prognosis and limited treatment options."

Kura expects to initiate a Phase 1 clinical trial of KO-947 in patients with a variety of solid tumors with dysregulation of the MAPK pathway in the first half of 2017. The company’s goal for its menin-MLL inhibitor program is to initiate a Phase 1 clinical trial in 2018.
