Agreement to Provide Clinical Development Services for Calithera's Lead Tumor Metabolism Product Candidate
SAN JOSE, CA. - ProTrials Research, Inc., a leader in the clinical research organization (CRO) industry, announced today the awarding and initiation of an agreement with Calithera Biosciences Inc., a clinical stage biotechnology company focused on the discovery and development of novel small molecule drugs directed against tumor metabolism and tumor immunology targets for the treatment of cancer. Under the agreement, ProTrials will provide clinical trial development support for the company's first-in-class inhibitor CB-839 program, which targets glutaminase, a critical enzyme in tumor metabolism. "We are extremely pleased that Calithera has selected ProTrials to support research into CB-839," said Jodi Andrews, Co-Founder and Co-CEO of ProTrials. "We recognize the potential of CB-839 to become an important therapeutic agent for the treatment of cancer, and look forward to applying our expertise to support Calithera's development of this first-in-class investigational compound." Calithera's CB-839 program is currently in Phase 1b clinical studies. Phase 1 data presented in June at the 2016 American Society of Clinical Oncology (ASCO) meeting in Chicago demonstrated the clinical activity, tolerability, and unique mechanism of action of CB-839 in patients with renal cell carcinoma (RCC) and triple negative breast cancer (TNBC). "ProTrials and Calithera share a commitment to high quality research and clinical innovation," said Susan Molineaux, PhD, President and Chief Executive Officer of Calithera.
