Ascletis Announces Positive Topline Results of Phase Ib Studies of ASC47 Monotherapy in Australia… (PRNewswire) - P1b | N=60 | NCT06427590 | Sponsor: Ascletis Pharma (China) Co., Limited | "ASC47, an adipose-targeted muscle-preserving weight loss drug candidate for the treatment of obesity, demonstrated a half-life of up to 26 days and 40 days, respectively, in Phase Ib single subcutaneous injection studies in healthy subjects with elevated LDL-C and patients with obesity, supporting once-monthly to once-bimonthly administration....ASC47 single subcutaneous injection (90 mg) in patients with obesity demonstrated a weight loss signal. Placebo-adjusted mean weight loss was 0.2% (day 29), 1.0% (day 43), and peaked at 1.7% (day 50), consistent with the speed of weight loss anticipated given ASC47's mechanism of action....The multiple ascending dose (MAD) study of ASC47 monotherapy for the treatment of obesity is expected to be initiated in the second half of 2025."

Ascletis Announces ASC47, a Muscle-Preserving Weight Loss Drug Candidate for Treatment of Obesity, in Combination with Semaglutide, Demonstrated Superior Weight Loss to Semaglutide Monotherapy in a Preclinical Model (PRNewswire) - "ASC47 low dose combination 1...treatment was superior to semaglutide monotherapy (30 nmol/kg, SQ, once daily), showing an average total body weight reduction of 36.2% compared to 23.1%, achieving 56.7% more relative weight loss compared to semaglutide monotherapy...ASC47 low dose combinations with semaglutide restored the body composition of obese mice to the level of healthy non-obese mice. At the end of treatment, the percentage of total muscle mass over the total body weight of obese mice treated with ASC47 low dose combination treatments (68.8%) was similar to healthy non-obese mice (66.0%), indicating healthy weight loss...ASC47 low dose combination treatments were well tolerated in obese mice and exhibited a statistically significant reduction in levels of liver enzymes such as alanine aminotransferase (ALT) compared to vehicle treatment in obese mice."

Interim data from a Phase I single ascending dose (SAD) study in Australia in subjects with elevated low-density lipoprotein cholesterol... (PRNewswire) - P1 | N=60 | NCT06427590 | Sponsor: Ascletis Pharma (China) Co., Limited | "Interim data...showed that ASC47, via SQ injection, demonstrated a half-life of 21 days. Further, ASC47 demonstrated a good tolerability profile up to 90 mg with no serious adverse events (SAEs) and no discontinuations due to adverse events (AEs). The majority of AEs were mild (grade 1). There were no gastrointestinal or cardiac AEs reported, as well as no abnormal liver enzymes reported (Link). The Australian SAD study is still ongoing with higher doses of ASC47...ASC47 is currently in the clinical trials of patients with obesity in Australia, with topline data of Phase IIa study expected in the second quarter of 2025."
