Corvus Pharmaceuticals Expands CPI-444 Clinical Collaboration with Genentech

CPI-444 in Combination with Atezolizumab Will Advance into Phase 1b/2 Study in Patients with Non-Small Cell Lung Cancer who are Resistant/Refractory to Prior Anti-PD(L)-1 Treatment as Part of MORPHEUS, Genentech’s Novel Cancer Immunotherapy Development Platform

BURLINGAME, Calif., May 02, 2017 -- Corvus Pharmaceuticals, Inc. (NASDAQ:CRVS), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel immuno-oncology therapies, today announced that it has expanded its clinical collaboration with Genentech, a member of the Roche Group. Under the new agreement, CPI-444 administered in combination with  atezolizumab (Tecentriq®) will be evaluated in a Phase 1b/2 clinical study as second-line therapy in patients with non-small cell lung cancer (NSCLC) who are resistant/refractory to prior therapy with an anti-PD(L)-1 antibody. The study will be part of MORPHEUS, Genentech’s novel cancer immunotherapy platform established to develop immunotherapy combination therapies more rapidly and efficiently. It is anticipated that this randomized, controlled study will enroll up to 65 patients in the treatment arm.

CPI-444, Corvus’ lead product, is a selective and potent inhibitor of the adenosine A2A receptor. Atezolizumab, developed by Genentech, is a monoclonal antibody designed to target and bind to a protein called PD-L1 (programmed death ligand-1).

“NSCLC patients who are resistant or refractory to prior treatment with anti-PD(L)-1 antibodies have few treatment options and we are very pleased that Genentech will include CPI-444 in MORPHEUS for this difficult-to-treat patient population,” said Richard A. Miller, M.D., an oncologist and co-founder, president and chief executive officer of Corvus. “CPI-444 has demonstrated promising clinical activity and good tolerability, both as a single agent and in combination with atezolizumab, including in patients with PD-L1 negative tumors. In addition to the inclusion of CPI-444 in MORPHEUS, these encouraging results have also allowed us to expand the size of four cohorts, including for NSCLC patients, in our ongoing Phase 1/1b trial.” 

Under the terms of the collaboration agreement, Genentech will manage study operations for the Phase 1b/2 trial, which is expected to begin enrolling patients in the second half of 2017. Financial terms were not disclosed and Corvus will retain global development and commercialization rights to CPI-444. The original clinical trial collaboration agreement between Corvus and Genentech, announced in October 2015, was for the multicenter Phase 1/1b trial, which is ongoing and continuing to examine the safety and clinical activity of CPI-444 as a single agent and in combination with atezolizumab in patients with multiple types of advanced solid tumors who previously failed standard therapies, including those resistant or refractory to prior treatment with anti-PD(L)-1 antibodies.

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 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.
