Case Report: Efficacy and safety of dose-escalated Mazdutide, a GLP-1/GCGR dual agonist, in an adolescent with obesity, type 2 diabetes, and hyperuricemia.

This case report describes the use of Mazdutide, a dual glucagon-like peptide-1/glucagon receptor (GLP-1/GCGR) agonist, in a 15-year-old male presenting with obesity (BMI 30.64 kg/m²), type 2 diabetes (HbA1c 9.60%), and hyperuricemia (serum uric acid 511 µmol/L). The patient received a dose-escalation regimen of subcutaneous once-weekly Mazdutide alongside metformin and insulin over 36 weeks. The authors report substantial improvements across multiple metabolic parameters: body weight decreased by 16.8 kg (18.89% BMI reduction), HbA1c fell by 21.88%, and serum uric acid dropped by 37.00%. Lipid outcomes also improved, with triglycerides declining 69.02%, total cholesterol 13.65%, and LDL cholesterol 17.27%. Hepatic steatosis, confirmed by ultrasound, resolved by week 14. No hypoglycemic episodes or other adverse events were reported, and benefits were described as sustained after treatment ended. Key limitations include the single-patient design, the absence of a control condition, and the concurrent use of metformin and insulin, making it impossible to attribute outcomes specifically to Mazdutide. These preliminary observations may inform future controlled studies in adolescent populations.

Mazdutide reduces body weight in adults with overweight or obesity: A high-dose Phase 1 trial.

This Phase 1 randomized, double-blind, placebo-controlled trial examined the safety and efficacy of mazdutide — a dual glucagon-like peptide-1 (GLP-1) and glucagon receptor agonist — at doses up to 16 mg in adults with overweight or obesity but without diabetes. Thirty-two participants received once-weekly subcutaneous injections of mazdutide (n=24, split across two dose-escalation cohorts) or placebo (n=8) for 20 weeks. The study found that both mazdutide cohorts experienced substantially greater mean percent reductions in body weight from baseline (approximately -20% and -21%, respectively) compared to the placebo group (approximately -0.1%), with statistically significant differences. The authors also reported improvements in metabolic markers and concluded that the 16 mg dose was well tolerated. Key limitations include the small sample size (particularly the placebo group of only 8 participants), the short 20-week duration, the Phase 1 design which is primarily safety-focused, and the absence of participants with diabetes, limiting generalizability. These findings suggest a dose-response relationship at higher doses than previously studied, but larger and longer trials are needed to confirm these results.
