Akeso Announces First Patient Enrolled in the Phase III Trial（AK112-312/HARMONi-GI6）of Ivonescimab for First-Line Treatment of Advanced Metastatic Colorectal Cancer

Core Viewpoint - Akeso, Inc. has initiated a Phase III clinical trial for ivonescimab as a first-line treatment for advanced metastatic colorectal cancer (mCRC), addressing a significant unmet clinical need in this area [1][2][7]. Industry Overview - Colorectal cancer is the third most common cancer globally and the second leading cause of cancer-related deaths, with over 1.9 million new cases and approximately 904,000 deaths reported in 2022 [3]. - About 95% of mCRC cases are classified as microsatellite stable (MSS) or proficient mismatch repair (pMMR), which traditionally show poor responses to immunotherapy [3]. - Current standard treatments for mCRC include chemotherapy combined with targeted therapies, but the overall efficacy remains limited, with a five-year survival rate for advanced patients of less than 20% [4]. Company Initiatives - The Phase III trial (AK112-312/HARMONi-GI6) aims to validate the clinical benefits of ivonescimab, which has shown promising Phase II efficacy data in combination with chemotherapy for MSS/pMMR-type mCRC [5][7]. - The combination of ivonescimab with FOLFOXIRI demonstrated an overall response rate (ORR) of 81.8% and a disease control rate (DCR) of 100%, indicating compelling anti-tumor activity in this difficult-to-treat patient population [6]. Future Prospects - If successful, ivonescimab could provide a novel first-line immunotherapy treatment option for patients with advanced mCRC, potentially improving outcomes compared to existing therapies [7].
