Corvus Pharmaceuticals Announces Partner Angel Pharmaceuticals Received IND Approval for Phase 1/1b Clinical Trial of Mupadolimab (Anti-CD73) in China

Mupadolimab clinical trial in China will be conducted by Angel PharmaceuticalsBURLINGAME, Calif., Sept. 26, 2022 (GLOBE NEWSWIRE) — Corvus Pharmaceuticals, Inc. (Corvus or the Company) (Nasdaq: CRVS), a clinical-stage biopharmaceutical company, today announced that the IND application to initiate a Phase 1/1b clinical trial of mupadolimab (formerly CPI-006) has been approved by the Center for Drug Evaluation of the China National Medical Products Administration. The study will be conducted by Angel Pharmaceuticals Ltd. (Angel Pharma), Corvus’ partner in China. Mupadolimab is a humanized monoclonal antibody designed to be directed against CD73 with a proposed unique mechanism of activating B cells to generate immune responses to tumor antigens and viruses, in patients with relapsed refractory non-small cell lung cancer (NSCLC) and head and neck squamous cell cancers (HNSCC). Corvus co-founded Angel Pharma to develop its pipeline in greater China. Angel Pharma licensed the rights from Corvus to develop, manufacture and commercialize mupadolimab in greater China. Corvus has studied mupadolimab in a Phase 1/1b clinical trial, with a focus on expansion cohorts in patients with (1) HNSCC that have failed previous treatment with anti-PD-1 therapy and chemotherapy and (2) relapsed refractory NSCLC who have failed previous treatment with anti-PD(L)-1 therapy and chemotherapy. Based on the results to-date, Corvus believes this program is ready to advance into a randomized Phase 2 clinical trial evaluating mupadolimab in combination with pembrolizumab and chemotherapy as a potential front-line therapy for the treatment of patients with NSCLC. “Our partnership with Angel Pharma continues to support the efficient development of our pipeline,” said Richard A. Miller, M.D., co-founder, president and chief executive officer of Corvus. “In our development work, we have characterized mupadolimab’s unique potential as an anti-CD73 antibody that blocks adenosine production and activates the immune system. Angel Pharma’s development strategy is consistent and supportive of our studies, with the potential to further expand mupadolimab’s opportunity in China and globally. They are continuing the development and clinical testing in patients with NSCLC and head and neck cancer.” Angel Pharma is examining mupadolimab in a Phase 1/1b clinical trial designed to confirm the dose and evaluate the safety, pharmacokinetics, immune biomarkers, and efficacy as a single agent, and in combination with pembrolizumab. Patients with NSCLC and HNSCC are eligible. The clinical trial’s efficacy endpoints are complete response, partial response, disease control rate, duration of response, progression-free survival, and overall survival.

Corvus’ lead product candidate is CPI-818, an investigational, oral, small molecule drug that selectively inhibited ITK in preclinical studies and is in a multicenter Phase 1/1b clinical trial in patients with several types of T-cell lymphomas. The Company’s second clinical program, ciforadenant (CPI-444), is an oral, small molecule inhibitor of the A2A receptor. Its third clinical program, mupadolimab (CPI-006), is a humanized monoclonal antibody directed against CD73 that has exhibited immunomodulatory activity and activation of immune cells in preclinical and clinical studies.

About MupadolimabMupadolimab (CPI-006) is an investigational, potent humanized monoclonal antibody that is designed to react with a specific site on CD73. In preclinical studies, it has demonstrated immunomodulatory activity resulting in activation of lymphocytes, induction of antibody production from B cells and effects on lymphocyte trafficking. While there are other anti-CD73 antibodies and small molecules in development for treatment of cancer, such agents react with a different region of CD73. Mupadolimab is designed to react with a region of the molecule that acts to stimulate B cells and block production of immunosuppressive adenosine. Mupadolimab has been studied in combination with pembrolizumab in a Phase 1b/2 clinical trial in patients with advanced HNSCC and in patients with NSCLC that have failed chemotherapy and anti-PD(L)1 therapy. It is postulated that the activation of B cells will enhance immunity within the tumors of these patients, leading to improved clinical outcomes.
