Corvus Pharmaceuticals Announces First Quarter 2016 Financial Results

Burlingame, Calif., May 5, 2016 — Corvus Pharmaceuticals, Inc. (NASDAQ: CRVS), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel immuno-oncology therapies, today announced financial results for the three months ended March 31, 2016.

“Since commencing operations in November 2014, we’ve made substantial progress and today, we have four product candidates in our pipeline focused on immuno-oncology therapies,” said Richard A. Miller, M.D., co-founder, president and chief executive officer of Corvus.

“In the first quarter of 2016, our achievements were particularly noteworthy as we commenced enrollment in an expansion cohort designed Phase 1/1b clinical trial to evaluate our novel oral checkpoint inhibitor, CPI-444, alone and in combination with atezolizumab, an investigational anti-PD-L1 antibody from Genentech in patients with solid tumors. We also successfully completed our IPO, raising $63.7 million in net proceeds before the partial exercise of the underwriters’ over-allotment option,” said Miller.

First Quarter 2016 Financial Results Compared To First Quarter 2015 Financial Results

At March 31, 2016, Corvus had cash and cash equivalents and marketable securities totaling $152.3 million, compared to $94.4 million at December 31, 2015.

Research and development costs for the three months ended March 31, 2016 totaled $5.4 million, compared with $1.9 million, for the prior period. The increase was primarily due to costs associated with commencing the Phase 1/1b clinical trial for the Company’s lead product candidate, CPI-444.

General and administrative costs for the three months ended March 31, 2016 totaled $1.0 million, compared to $0.3 million for the prior period, due to increased headcount and professional fees associated with the Company’s preparation for being a public company.

The net loss for the three months ended March 31, 2016 was $6.3 million compared to a net loss for the three months ended March 31, 2015 of $1.9 million.

Additionally, in April 2016, the underwriters of the Company’s IPO exercised their over-allotment option and purchased 502,618 shares of Corvus’s common stock resulting in net proceeds to the Company of $7.0 million.

About Adenosine A2A Receptor Antagonists

Over the last several years, significant progress has been made in developing immunotherapies for the treatment of cancer, in part due to the development of checkpoint inhibitors — antibodies that block immuno-suppressive mechanisms.

Tumors evade immune attack by usurping pathways that negatively regulate immune responses. Adenosine in the tumor microenvironment leads to the activation of the A2A receptor and has been shown to represent one such negative immune regulatory mechanism. Because the tumor microenvironment produces relatively high concentrations of adenosine, blocking A2A receptor activation has the potential to enhance anti-tumor immunity. Data have demonstrated the ability of A2A receptor blockade to enhance anti-tumor immunity, checkpoint blockade and adoptive T-cell therapy. Studies to date support the development of A2A receptor antagonists as novel immunotherapy treatments.

About CPI-444

CPI-444, Corvus’s 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.

Corvus is currently evaluating CPI-444 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 atezolizumab (MPDL3280A), Genentech’s investigational cancer immunotherapy. Atezolizumab is a fully humanized monoclonal antibody targeting protein programmed cell death ligand 1 (PD-L1). 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.
