Effect of once-weekly subcutaneous semaglutide 2.4mg on weight- and health-related quality of life in an East Asian population: Patient-reported outcomes from the STEP 6 trial.

Abstract

We assessed the effect of semaglutide 2.4 and 1.7mg versus placebo on weight-related quality of life (WRQOL) and health-related quality of life (HRQOL) in the STEP 6 trial. Adults from East Asia (body mass index [BMI] ≥27.0kg/m2 with ≥2 weight-related comorbidities, or ≥35.0kg/m2 with ≥1 weight-related comorbidity) were randomized 4:1:2:1 to once-weekly subcutaneous semaglutide 2.4mg or placebo, or semaglutide 1.7mg or placebo, plus lifestyle intervention for 68 weeks. WRQOL and HRQOL were assessed from baseline to Week 68 using the Impact of Weight on Quality of Life-Lite Clinical Trials Version (IWQOL-Lite-CT) and the 36-Item-Short-Form-Survey-version-2.0 acute (SF-36v2), with changes in scores by categories of baseline BMI (</≥30 and ≥35 kg/m2 ) also assessed. In total, 401 participants (mean body weight 87.5kg, aged 51 years, BMI 31.9kg/m2 , waist circumference 103.2cm) were included. From baseline to Week 68, the IWQOL-Lite-CT Psychosocial and Total scores were significantly improved with semaglutide 2.4 and 1.7mg versus placebo. For Physical score, effects were only in favour of semaglutide 2.4mg versus placebo. In the SF-36v2, Physical Functioning was significantly improved with semaglutide 2.4mg versus placebo, but no beneficial effects favouring either semaglutide treatment arms versus placebo were seen in the other SF-36v2 domains. Benefits favouring semaglutide 2.4mg versus placebo were also observed in subgroups with higher BMIs for IWQOL-Lite-CT and SF-36v2 Physical Functioning scores. Treatment with semaglutide 2.4mg improved aspects of WRQOL and HRQOL in people from East Asia with overweight/obesity.
