ASC30 / Ascletis - LARVOL DELTA

A Full Analysis of 28-Day MAD Study of Oral GLP-1R Biased Small Molecule Agonist ASC30 for Obesity (OBESITY WEEK 2025) - "In this MAD study, ASC30 once-daily oral tablet administration demonstrated statistically significant weight loss, with mean percent body weight changes from baseline up to -6.3% after only 28 days of oral dosing. ASC30 tablets exhibited a favorable tolerability profile. These findings position the ASC30 once-daily oral tablet as a potential best-in-class investigational agent for weight management."

ASC30, a Once-Monthly SQ Injected Small Molecule GLP-1RA in Participants with Obesity: A Ph Ib Study (OBESITY WEEK 2025) - "As a potentially first-in-class SQ injected small molecule GLP-1R agonist, ASC30 demonstrated a 36.3-day half-life, supporting once-monthly or less frequent administration. All three evaluated formulations were well tolerated, with a favorable safety profile, minimal gastrointestinal adverse events, and no serious or grade ≥3 adverse events. This neutral-pH stable sterile solution formulation of ASC30 is advancing into further clinical trials to evaluate higher doses for obesity treatment and offering a potentially convenient, ultra-long-acting therapeutic option."
