Core Viewpoint - The National Medical Products Administration (NMPA) has approved the launch of the anti-CTLA-4 monoclonal antibody, Ipilimumab N01 injection (brand name: Daberxin), developed by Innovent Biologics, for neoadjuvant treatment in patients with resectable stage IIB-III microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) colorectal cancer, marking it as China's first domestically approved anti-CTLA-4 monoclonal antibody and the first globally for this indication [1][5]. Group 1 - The approval is based on the results of a randomized, controlled, multi-center Phase III registration study (NeoShot-III, NCT05890742) conducted in China, which aimed to evaluate the efficacy and safety of Ipilimumab N01 in combination with Sintilimab compared to direct radical surgery [3][7]. - The primary endpoints of the study included pathological complete response (pCR) and event-free survival (EFS) [3][7]. - The interim analysis of the NeoShot-III study showed that the predefined primary endpoints were met, as assessed by the Independent Data Monitoring Committee (iDMC) [3][7]. Group 2 - As of November 28, 2024, among the first 50 patients in the trial group, 41 achieved pathological complete response after neoadjuvant treatment, resulting in a pCR rate of 82% [4][8]. - In terms of safety, the combination of Ipilimumab N01 and Sintilimab did not significantly increase additional safety risks compared to the direct surgery group [4][8]. - The Chief R&D Officer of Innovent Biologics, Dr. Zhou Hui, emphasized the significant unmet clinical need for neoadjuvant treatment in resectable MSI-H/dMMR colorectal cancer, highlighting the importance of the NeoShot-III study's interim analysis for this treatment area [4][8].
