Ascletis Unveils ASC47 Weight Loss Drug Candidate

The combination of ASC47 low dose with tirzepatide led to an 87% greater reduction in body weight in diet-induced obese mice compared to tirzepatide alone.
ASC47 low dose combined with tirzepatide showed a statistically significant increase in efficacy over ASC47 with semaglutide, with reductions of 87% versus 55%.
The combination treatment restored body composition in obese mice to that of healthy non-obese mice, with total muscle mass percentages of 60.4% for the treated mice and 62.0% for healthy mice.
Upcoming topline data on ASC47 combined with semaglutide will guide future trials involving ASC47 with other incretin drugs, including tirzepatide.
