Ascletis ASC36 Amylin Receptor Peptide Agonist Once-Monthly to Once-Quarterly Phase 1 Enrollment Continues in U.S. Obesity Study
Ascletis Pharma (HKEX: 1672) continued enrollment through early September 2026 in the two U.S. Phase 1 studies of ASC36 (a once-monthly to once-quarterly subcutaneous amylin receptor peptide agonist for obesity) and ASC36_35FDC (a once-monthly subcutaneous fixed-dose combination of ASC36 plus GLP-1R/GIPR peptide agonist ASC35) initiated August 10, 2026 following FDA IND clearance July 5. In head-to-head diet-induced-obesity rat studies, ASC36 monotherapy demonstrated approximately 91% greater relative body weight reduction versus Zealand-Roche's petrelintide and approximately 32% greater versus Eli Lilly's eloralintide. If the Phase 1 tolerability profile confirms preclinical differentiation, ASC36 would enter the amylin analog Phase 2 field alongside Novo Nordisk's cagrilintide-in-CagriSema, AstraZeneca's AZD6234 (Rome EASD 2026 September 28-October 2 readout), Metsera's MET-233i, and the Roche-Zealand petrelintide-plus-enicepatide combination Phase 2 initiation planned mid-2026.
