A Study of IBI363 Combination Therapy in Participants With Advanced Solid Tumors

CIBI363A203, a Phase 2 study to evaluate the safety, tolerability and preliminary efficacy of IBI363 combined with IBI305 (a bevacizumab biosimilar) in participants with advanced malignancies conducted in China. Primary endpoint is objective response rate (ORR) per RECIST v1.1. Secondary endpoints include DoR, DCR, TTR, PFS, per RECIST v1.1, and OS; the incidence and severity of AEs, irAEs, SAEs, AESIs and their relationship to the investigational drug, and changes in vital signs, physical examination, and laboratory values before and after study treatment; PK, and immunogenicity of IBI363. The cohorts include: IBI363 and IBI305 combination therapy in participants with advanced EGFRmut NSCLC progressed after EGFR TKI and Platinum-based chemotherapy, and advanced platinum-resistant ovarian cancer (PROC). The anticipated enrollment for this study is approximately 60 participants with each cohort 30 participants, and actual enrollment may change with future amendments as cohorts are opened and closed based on evolving data.
