CStone Submits Clinical Trial Application for CS2009, a PD-1/VEGF/CTLA-4 Trispecific Antibody

• 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.
