BURLINGAME, Calif., Oct. 10, 2016 (GLOBE NEWSWIRE) -- Corvus Pharmaceuticals, Inc. (NASDAQ:CRVS), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel immuno-oncology therapies, today announced biomarker findings from its ongoing Phase 1/1b study of CPI-444 as a single agent and in combination with Genentech’s TECENTRIQ® (atezolizumab), a fully humanized monoclonal antibody targeting protein programmed cell death ligand 1 (PD-L1). CPI-444 is a selective and potent inhibitor of the adenosine A2A receptor. The data were presented today in a poster session by Ian McCaffery, Ph.D., vice president, Translational Sciences at Corvus, at the European Society for Medical Oncology (ESMO) 2016 Congress at the Bella Center in Copenhagen, Denmark.
“The initial part of our Phase 1/1b trial was designed to provide data on optimum dosing, safety and relevant biomarkers, and we have achieved that goal. We have completed enrollment in the dose-selection part of the trial, which enrolled 48 patients in four cohorts. We now have a solid understanding of dose, schedule, pharmacodynamic parameters and biomarkers,” said Richard A. Miller, M.D., an oncologist and co-founder, president and chief executive officer of Corvus. “We have selected the optimum single agent and combination dose of CPI-444 for the disease-specific expansion stage of the trial, which is now enrolling patients at 30 centers in the United States, Canada and Australia. We plan to present preliminary efficacy data from the dose-selection part of the study later this year.”
Results presented showed:
CPI-444, Corvus’ lead checkpoint inhibitor, is an adenosine A2A receptor antagonist. It is designed to disable a tumor’s ability to subvert attack by the immune system by inhibiting adenosine in the tumor microenvironment. CPI-444 is a small molecule that is taken orally. It is in development as an immuno-oncology therapy for the treatment of patients with solid tumors.
About the Phase 1/1b Trial
The Phase 1/1b trial is designed to examine the activity of CPI-444 as a single agent and in combination with Genentech’s TECENTRIQ (atezolizumab), an anti-PD-L1 antibody. Patients with non-small cell lung cancer, melanoma, renal cell cancer, triple-negative breast cancer, colorectal cancer, head and neck cancer, bladder cancer and prostate cancer who have failed all standard therapies are eligible.
The first part of the study (dose-selection) included four cohorts of 12 patients each (N=48) – three cohorts treated with single agent CPI-444 (100 mg twice daily for 14 days; 100 mg twice daily for 28 days; 200 mg once daily for 14 days) and one cohort treated with the combination (CPI-444 50 mg or 100 mg twice daily for 14 days combined with TECENTRIQ). A treatment cycle is 28 days. Based on safety and biomarker analyses, an optimum single agent and combination dose were selected. The second part of the study is evaluating CPI-444 as a single agent in five disease-specific cohorts, and CPI-444 in combination with TECENTRIQ in five additional matched disease-specific cohorts. Corvus expects that each of these 10 cohorts will initially enroll 14 patients, but each cohort may be expanded based on efficacy.
About Corvus Pharmaceuticals
Corvus Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the development and commercialization of small molecule and antibody agents that target the immune system to treat patients with cancer. These agents block or modify crucial immune checkpoints and reprogram immune T-cells. Corvus’ lead product, CPI-444, is a checkpoint inhibitor that is designed to disable a tumor’s ability to subvert attack by the immune system by inhibiting adenosine in the tumor microenvironment. CPI-444 is a small molecule that is taken orally. CPI-444 is currently being evaluated in a multicenter Phase 1/1b clinical trial in patients with various solid tumors. This successive expansion cohort trial is examining the activity of CPI-444 both as a single agent and in combination with Genentech’s TECENTRIQ (atezolizumab), an anti-PD-L1 antibody. Corvus is conducting the trial with Genentech, a member of the Roche Group, under a clinical trial collaboration the two companies entered into in October 2015.
