• CStone Pharmaceuticals has submitted a clinical trial application in Australia for CS2009, a trispecific antibody targeting PD-1, VEGFA, and CTLA-4.
• CS2009's design aims to preferentially target tumor-infiltrating lymphocytes, potentially reducing systemic toxicity while maintaining efficacy in solid tumors.
• Preclinical data presented at SITC 2024 demonstrated CS2009's superior anti-tumor activity compared to other immunotherapies across various cancer types.
• A first-in-human trial is planned for early 2025 in Australia, with subsequent expansion into China and the United States.
