Research Study Investigating How Well Semaglutide Works in People With Type 2 Diabetes Suffering From Overweight or Obesity

Phase 3

Completed

• Conditions: Obesity; Overweight
• Interventions: Drug: Semaglutide 2.4 mg; Drug: Semaglutide 1.0 mg; Drug: Placebo I (Semaglutide); Drug: Placebo II (Semaglutide)

• Registration Number: NCT03552757
• Lead Sponsor: Novo Nordisk A/S

Brief Summary

This study will look at the change in the participant's body weight from the start to the end of the study. This is to compare the effect on body weight in people taking semaglutide (a new medicine) and people taking "dummy" medicine. In addition to taking the study medicine, the participant will have talks with study staff about healthy food choices, how to be more physically active and what else the participant can do to lose weight. Overweight and obesity is associated with an increased risk of type 2 diabetes. Therefore, weight loss has shown to have a beneficial impact on the blood sugar levels. The participant will either get semaglutide or "dummy" medicine - which treatment the participant get is decided by chance. The participant will need to take 2 injections at the same time once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The study will last for about 1.5 years

Change in Short Form 36 v2.0 Acute (SF-36) (Physical Functioning Score)	Baseline (week 0) to week 68	SF-36 is a 36-item patient-reported survey of patient health that measures the participant's overall health-related quality of life (HRQoL). SF-36v2™ questionnaire measured 8 domains of functional health and well-being as well as 2 component summary scores (physical component summary and mental component summary). This endpoint shows results for 'physical functioning domain'. The 0-100 scale scores from the SF-36 were converted to norm-based scores to enable a direct interpretation in relation to the distribution of the scores in the 2009 U.S. general population. In the metric of norm-based scores, 50 and 10 corresponds to the mean and standard deviation respectively. Change from week 0 in the domain scores were evaluated at week 68. A positive change score indicates an improvement since baseline. Results are based on the data from in-trial observation period.
