A Single-Arm, Phase II Study of Retlirafusp Alfa in Combination With XELOX and Bevacizumab for the First-Line Treatment of Advanced RAS-Mutated Colorectal Cancer With Liver Metastases (CRLM)

This single-arm phase II trial enrolls patients with RAS-mutant, microsatellite-stable (MSS) unresectable colorectal cancer liver metastases receiving first-line treatment with Retlirafusp alfa combined with XELOX (capecitabine plus oxaliplatin) and bevacizumab. The primary endpoint is objective response rate (ORR). A total of 46 patients will be enrolled, and the study is expected to be completed between 2026 and 2029.
