Core Insights - Ascletis Pharma Inc. has selected ASC37 injection, a next-generation GLP-1R/GIPR/GCGR triple peptide agonist, for clinical development, with an Investigational New Drug Application (IND) submission to the FDA expected in Q2 2026 [2][5]. Group 1: Product Development - ASC37 has an average observed half-life of approximately 17 days in non-human primate studies, which is 7-fold longer than retatrutide, supporting once-monthly subcutaneous dosing [1][4]. - The in vitro activity of ASC37 is approximately 5-fold, 4-fold, and 4-fold more potent than retatrutide for GLP-1R, GIPR, and GCGR, respectively [1][3]. - ASC37 is engineered for a longer half-life compared to retatrutide, allowing for a subcutaneous injection volume of one milliliter or less, which also provides manufacturing scalability advantages [3][4]. Group 2: Clinical Strategy - The company plans to initiate a Phase I study for ASC37 in the second half of 2026, as part of its strategy to enhance treatment options for obesity [5]. - ASC37 is being developed both as a monotherapy and in combination with ASC36, another peptide agonist, to address cardio-metabolic diseases including obesity and diabetes [5]. Group 3: Technological Innovation - Ascletis utilizes its proprietary Artificial Intelligence-assisted Structure-Based Drug Discovery (AISBDD) and Ultra-Long-Acting Platform (ULAP) technologies to design and optimize multiple once-monthly subcutaneous ultra-long-acting peptides [6][8]. - The ULAP technology allows for precise control over the release of peptides, improving clinical outcomes by reducing peak-to-trough ratios [6].
