Ascletis Begins Dosing in Phase IIa Trial of ASC30 for Obesity Treatment
- Ascletis Pharma announced on July 2, 2025, that it dosed first participants in a U.S. multi-center 13-week Phase IIa trial of oral GLP-1 receptor agonist ASC30 for obesity treatment.
- This trial follows earlier Phase Ia and Ib studies showing ASC30's tolerability and up to 6.5% placebo-adjusted weight reduction over four weeks, with screening started in June 2025.
- The randomized, double-blind, placebo-controlled study enrolls adults with BMI ≥30 kg/m² or overweight with weight-related comorbidities, using a slow titration to maintenance doses up to 60 mg weekly.
- Ascletis CEO Jinzi Jason Wu stated, “We are ahead of schedule” and expects topline Phase IIa data in the fourth quarter of 2025; ASC30 has patent protection until 2044.
- If approved, ASC30 could offer a once-daily oral treatment option for obesity, complementing existing FDA-approved injectable GLP-1 receptor agonists and advancing metabolic disease therapeutics.
