Conference Call Today at 4:30 p.m. ET / 1:30 p.m. PT
BURLINGAME, Calif., March 05, 2020 (GLOBE NEWSWIRE) -- Corvus Pharmaceuticals, Inc. (Nasdaq: CRVS), a clinical-stage biopharmaceutical company focused on the development and commercialization of precisely targeted oncology therapies and the utilization of novel biomarkers to enhance patient selection, today provided a business update and reported financial results for the fourth quarter and year ended December 31, 2019.
“In 2019, we continued to efficiently advance our pipeline and exited the year with three candidates in clinical trials,” said R ichard A. Miller, M.D., co-founder, president and chief executive officer of Corvus. “We have presented updated data for each of these programs at major medical meetings and our academic collaborators are beginning to publish data from our studies in peer-reviewed journals, including a key publication for ciforadenant, our most advanced product, in
in January. This article presented results demonstrating responses in patients with advanced refractory renal cell cancer and also reported on the identification of the Adenosine Gene Signature, a novel predictive biomarker.”
“We presented data from our ongoing Phase 1/1b clinical trial with ciforadenant in prostate cancer at the American Society of Clinical Oncology Genitourinary Cancer Symposium (ASCO GU) meeting in February 2020 and on CPI-818 at the T-Cell Lymphoma Forum in January 2020. We look forward to reporting more mature data from these trials during the year.”
CPI-444: A2A Receptor Antagonist of Adenosine
Publication of peer-reviewed study in
covering results in 68 patients with advanced refractory renal cell cancer (RCC) treated with ciforadenant monotherapy and in combination with Genentech’s Tecentriq® (atezolizumab), an anti-PD-L1 antibody. The publication describes the discovery of the Adenosine Gene Signature, which was shown in the study to identify patients most likely to respond to treatment with ciforadenant. In the 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.
Enrolled additional patients (25 to date) with advanced refractory RCC in an amended Phase 1b/2 clinical trial evaluating ciforadenant in combination with Tecentriq intended to further evaluate the findings of the 68 patient study published in
. To date, the results appear consistent with earlier results that Adenosine Gene Signature positive patients are more likely to respond to ciforadenant.
Presentation of 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 in February 2020. The preliminary data indicated that ciforadenant is active in mCRPC, and that the Adenosine Gene Signature correlated with CD73 expression in tumor biopsies.
CPI-006: Anti-CD73 Antibody
Oral presentation summarizing the safety and immunologic effects of CPI-006 in a phase 1/1b clinical trial at the Society for Immunotherapy of Cancer (SITC) in November 2019. The presentation reported the in vivo effects of CPI-006 on B-cell activation, function and migration, supporting a new immuno-oncology approach with CPI-006 via activation of immune cells and the inhibition of adenosine production.
The trial will enroll up to 350 patients with advanced cancer evaluating CPI-006 as a single agent and in combination with ciforadenant or pembrolizumab.
Selected recommended dose of 18 mg/kg, or a fixed dose of 1200 mg, and initiated the disease expansion phase in the monotherapy and in combination with ciforadenant arms of the study. CPI-006 was well tolerated at all levels, with no dose limiting toxicities (doses ranged from 1 to 18 mg/kg).
Initiated enrollment in the combination cohort of CPI-006 and pembrolizumab.
Preliminary anti-tumor activity has been seen in mCRPC and renal cell cancer using monotherapy and in combination with ciforadenant.
CPI-818: A small molecule ITK inhibitor
Presentation of safety, pharmacokinetics and immunologic effects of CPI-818 in patients with refractory T-cell lymphomas in a poster at the American Society of Hematology (ASH) annual meeting in December 2019 and in an oral session at the T-Cell Lymphoma Forum in January. These studies demonstrated that CPI-818 blocked proliferation of lymphoma cells in vitro.
The presentation at the T-Cell Forum reported on Phase 1 data in 16 patients. No dose limiting toxicities were observed at doses up to 600 mg oral, twice per day. Two patients with cutaneous T-cell lymphoma (CTCL) have shown improvement and 11 patients remained on the study as of the data cut-off date of January 2020.
Receptor occupancy studies indicate that complete occupancy may occur with doses of 600 mg twice per day.
As of December 31, 2019, Corvus had cash, cash equivalents and marketable securities totaling $78.0 million. This amount compared to cash, cash equivalents and marketable securities of $114.6 million at December 31, 2018. Corvus expects full year 2020 net cash used in operating activities to be between $39 million and $42 million.
Research and development expenses for the three months and full year ended December 31, 2019 totaled $8.9 million and $38.0 million, respectively, compared to $8.4 million and $38.6 million for the same periods in 2018. In the fourth quarter of 2019, the increase of $0.5 million was primarily due to an increase in outside CPI-006 and CPI-818 costs, partially offset by a decrease in outside ciforadenant costs. For the full year 2019, the decrease of $0.6 million was primarily due to a decrease in outside ciforadenant costs, partially offset by an increase in outside CPI-006 and CPI-818 costs and an increase in personnel costs.
The net loss for the three months and year ended December 31, 2019 was $11.0 million and $46.7 million, respectively, compared to $10.5 million and $46.9 million for the same periods in 2018. Total stock compensation expense for the three months and year ended December 31, 2019 was $1.7 million and $7.3 million, respectively, compared to $1.8 million and $7.1 million for the same periods in 2018.

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 in combination with 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.
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 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.
