Mazdutide as Adjuvant Therapy Following Sleeve Gastrectomy in Severe Obesity

After sleeve gastrectomy is preformed, mazdutide injection (pre-filled auto-injector pen) is administered subcutaneously at the same time each week at 5th month post procedure. The treatment begins with a starting dose of 2.0 mg, followed by a titration schedule increasing by 2.0 mg every 4 weeks (2.0 mg → 4.0 mg). If well-tolerated, participants reached the target maintenance dose of 6.0 mg (4.0 mg → 6.0 mg)weekly for maintenance. The protocol permits adaptive dose downgrade to 4.0 mg weekly when clinically indicated, such as intolerance. The total intervention is maintained until 48 weeks post procedure.

After sleeve gastrectomy is preformed, mazdutide placebo injection (pre-filled auto-injector pen) is administered subcutaneously at the same time each week at 5th month post procedure. The treatment begins with a starting dose of 2.0 mg placebo, followed by a titration schedule increasing by 2.0 mg every 4 weeks (2.0 mg → 4.0 mg). If well-tolerated, participants reached the target maintenance dose of 6.0 mg placebo(4.0 mg → 6.0 mg) weekly for maintenance. The protocol permits adaptive dose downgrade to 4.0 mg weekly when clinically indicated, such as intolerance. The total intervention is maintained until 48 weeks post procedure.
