Corvus Pharmaceuticals Provides Business Update and Reports First Quarter 2020 Financial Results
“In the first quarter, we continued enrolling patients across our three clinical stage programs and reported positive data updates for ciforadenant, the Adenosine Gene Signature, and CPI-818,” said
“We also worked closely with our clinical trial sites to quickly adapt and update our study protocols to ensure patient and healthcare provider safety in light of the COVID-19 pandemic. We are pleased that this enabled enrollment and follow-up activities for patients in our studies to continue with minimal disruption. Fortunately, we have had strong enrollment in our clinical studies up to this point, allowing us to collect important clinical data as the studies mature.”
Ciforadenant (CPI-444): A2A Receptor Antagonist of Adenosine
- Enrolled 25 patients with advanced refractory renal cell cancer (RCC) in an amended phase 1b/2 clinical trial evaluating ciforadenant in combination with Genentech’s Tecentriq® (atezolizumab), an anti-PD-L1 antibody, intended to confirm earlier results published in Cancer Discovery describing the Adenosine Gene Signature, which is designed to identify patients most likely to respond to treatment with ciforadenant. In the Cancer Discovery study, for patients with available tumor biopsies, Adenosine Gene Signature positive patients had a 17% overall response rate by RECIST criteria vs 0% in Adenosine Gene Signature negative patients. Initial clinical data from the 25-patient RCC cohort is expected to be delivered in a presentation at the 2020
American Society of Clinical Oncology (ASCO) VirtualAnnual Meeting in May 2020.
- Presented safety and preliminary efficacy data in 35 patients with advanced refractory metastatic castrate resistant prostate cancer (mCRPC) treated with ciforadenant monotherapy and in combination with Tecentriq at the ASCO GU Cancer Symposium. The preliminary data indicated that ciforadenant is active in mCRPC, and that the Adenosine Gene Signature correlated with CD73 expression in tumor biopsies. Treatment and follow up in this study continues.
CPI-006: Anti-CD73 Antibody with Immunomodulatory Activity
- Completed enrollment in the first two arms of the CPI-006 phase 1/1b clinical trial: monotherapy and combination with ciforadenant. The trial, which will enroll up to 350 patients, continues to enroll patients in its other two arms: combination with pembrolizumab and triplet combination with ciforadenant and pembrolizumab. Updated clinical data from the phase 1/1b clinical trial is targeted to be presented at the
Society for Immunotherapy of Cancer(SITC) annual meeting in November 2020.
- Generated positive pre-clinical data demonstrating that CPI-006 activates B-cells and enhances antibody responses in vitro. Human clinical data from the ongoing clinical trial in cancer continues to demonstrate B-cell activation leading to generation of anti-tumor antibodies in some patients.
CPI-818: A small molecule ITK inhibitor
- Completed enrollment in the dose escalation portion of the CPI-818 phase 1/1b clinical trial, which included patients with several types of advanced, refractory T-cell lymphomas. Based on results from this portion of the study, the Company selected the CPI-818 optimum dose and began the next portion of the study with a focus on patients with cutaneous T-cell lymphoma (CTCL).
Anticipated Events in 2020
- As noted above, the Company will present updated data covering ciforadenant and the Adenosine Gene Signature in RCC at the 2020 ASCO Virtual Annual Meeting in
- The Company plans to meet with
U.S. Food & Drug Administration(FDA) to discuss the study design and plans for a ciforadenant pivotal study in advanced refractory RCC using the Adenosine Gene Signature as a biomarker.
- Updated clinical data from the CPI-006 phase 1/1b clinical trial is planned to be presented at the SITC annual meeting in
- Updated clinical data from the CPI-818 phase 1/1b clinical trial is planned to be presented at the
American Society of Hematology(ASH) annual meeting in December 2020.

About Corvus Pharmaceuticals
Corvus Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the development and commercialization of precisely targeted oncology therapies. Corvus’ lead product candidates are ciforadenant (CPI-444), a small molecule inhibitor of the A2A receptor, and CPI-006, a humanized monoclonal antibody directed against CD73 that exhibits immunomodulatory activity and blockade of adenosine production. These product candidates are being studied in ongoing Phase 1/1b and Phase 1b/2 clinical trials in patients with a wide range of advanced solid tumors. Ciforadenant is being evaluated in a successive expansion cohort Phase 1b/2 trial examining its activity both as a single agent and in combination with an anti-PD-L1 antibody. CPI-006 is being evaluated in a multicenter Phase 1/1b clinical trial as a single agent, in combination with ciforadenant and pembrolizumab. The Company’s third clinical program, CPI-818, an oral, small molecule drug that has been shown to selectively inhibit ITK, is in a multicenter Phase 1/1b clinical trial in patients with several types of T-cell lymphomas.

Ciforadenant (CPI-444) is a small molecule, oral, checkpoint inhibitor designed to disable a tumor’s ability to subvert attack by the immune system by blocking the binding of adenosine in the tumor microenvironment to the A2A receptor. Adenosine, a metabolite of ATP (adenosine tri-phosphate), is produced within the tumor microenvironment where it may bind to the adenosine A2A receptor present on immune cells and block their activity. CD39 and CD73 are enzymes on the surface of tumor cells and immune cells. These enzymes work in concert to convert ATP to adenosine. In vitro and preclinical studies have shown that dual blockade of CD73 and the A2A receptor may be synergistic.
Adenosine Gene Signature
The adenosine gene signature is a biomarker that reflects adenosine induced immunosuppression in the tumor. These genes express chemokines that recruit myeloid cells including immunosuppressive tumor associated macrophages, which are thought to mediate resistance to anti-PD(L)1 treatment. To date, in our clinical trial of renal cell cancer, this biomarker has been associated with a higher rate of response to ciforadenant.
CPI-006 is a potent humanized monoclonal antibody that reacts with the active site of CD73, blocking the conversion of AMP to adenosine. This antibody also possesses immunomodulatory activity resulting in activation of lymphocytes, induction of antibody production from B cells and effects on lymphocyte trafficking, which are independent of adenosine. In vitro studies of CPI-006 have shown it is capable of substantially inhibiting the production of adenosine by blocking the CD73 enzyme.
CPI-818 is a small molecule drug given orally that has been shown to selectively inhibit ITK (interleukin-2-inducible T-cell kinase). It was developed to possess dual properties: to block malignant T-cell growth and modulate immune responses. ITK, an enzyme, is expressed predominantly in T-cells and plays a role in T-cell and natural killer (NK) cell lymphomas and leukemias, as well as in normal immune function. Interference with ITK signaling can modulate immune responses to various antigens. The inhibition of specific molecular targets in T-cells may be of therapeutic benefit for patients with T-cell lymphomas.
