Non-diabetic Obesity
Conditions
Brief summary
This study aims to evaluate the efficacy and safety of PEG-rhGH Injection combined with Semaglutide Injection versus Semaglutide Injection monotherapy in improving body composition (lean body mass, fat mass, etc.) in non-diabetic obese adults, while also analyzing changes in body weight, blood glucose, and other metabolic parameters.
Interventions
Polyethylene Glycol Recombinant Human Growth Hormone Injection (PEG-rhGH Injection), 54 IU/9.0 mg/1.0 mL/amp.; Subcutaneous injection using pen-injector, once weekly at a dose of 2 mg per week (weeks 1-40). Semaglutide Injection, 0.68 mg/mL,1.5 mL;1.34 mg/mL,1.5 mL;1.34 mg/mL,3 mL;2.27 mg/mL,3 mL;3.2 mg/mL,3 mL; Subcutaneous injection once weekly using pre-filled pen including dosage escalation period (W1-W16): starting dose 0.25 mg, increasing every 4 weeks (0.25 mg, 0.5 mg, 1.0 mg, 1.7 mg, 2.4 mg) and maintenance treatment period (W17-W40): at a dose of 2.4 mg for 24 weeks
