Phase 1/1b Study to Evaluate the Safety and Tolerability of Ciforadenant Alone and in Combination With Atezolizumab in Advanced Cancers
August 27, 2021 updated by: Corvus Pharmaceuticals, Inc.
A Phase 1/1b, Open-Label, Multicenter, Repeat-Dose, Dose-Selection Study of Ciforadenant as Single Agent and in Combination With Atezolizumab in Patients With Selected Incurable Cancers
This is a phase 1/1b open-label, multicenter, dose-selection study of ciforadenant, an oral small molecule targeting the adenosine-A2A receptor on T-lymphocytes and other cells of the immune system.
This trial will study the safety, tolerability, and anti-tumor activity of ciforadenant as a single agent and in combination with atezolizumab, a PD-L1 inhibitor against various solid tumors.
Ciforadenant blocks adenosine from binding to the A2A receptor.
Adenosine suppresses the anti-tumor activity of T cells and other immune cells.

- Measurable disease according to RECIST v1.1
- Mandatory newly collected tumor biopsy sample obtained prior to treatment initiation.
Renal Cell Carcinoma Exclusion Criteria
- History of severe hypersensitivity reaction to monoclonal antibodies.
- Has immunodeficiency or requires treatment with systemic immunosuppressive medication within 2 weeks prior to initiation of study treatment or anticipation of need for systemic immunosuppressant medication during study treatment.
