ASCEND-1: Lifestyle Intervention Plus Mazdutide for Weight Management

Официальное название

Achieving Sustained Weight Control Via Exercise, Nutrition & Drugs (Mazdutide) (ASCEND- 1 Trial)

Обзор

Obesity is a chronic, progressive, and relapsing disease. Although lifestyle interventions and anti-obesity medications are effective for inducing weight loss, evidence regarding their role in long-term weight maintenance after pharmacologically induced weight reduction remains limited. In addition, the high cost and potential adverse effects of weight-loss medications restrict their prolonged use, and it is unclear whether low dose medication, intensive life style intervention or together can serve as an effective strategy for weight maintenance. This randomized controlled trial aims to evaluate the effectiveness of a 1-year intensive lifestyle intervention, a reduced dose of mazdutide (3.0 mg once weekly), or their combination in weight maintenance among individuals with obesity who have achieved initial weight loss after intensive treatment with high dose mazdutide. The study seeks to provide high-quality clinical evidence to inform long-term weight maintenance strategies after weight loss in patients with obesity.
