Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Sema 2.4 mg | Participants were to receive once-weekly subcutaneous (s.c) injection of 0.25 mg Semaglutide administered using a PDS290 pre-filled pen-injector with a 3 mL cartridge containing Semaglutide 1.0 mg/mL or 3.0 mg/mL and followed a fixed-dose escalation regimen, with dose increases every 4 weeks (to doses of 0.5, 1.0, 1.7 and 2.4 mg/week), aiming at reaching the maintenance dose of 2.4 mg after 16 weeks. Treatment was continued on the maintenance dose of 2.4 mg Semaglutide once weekly for an additional 52 weeks until week 68. The treatment was an adjunct to a reduced-calorie diet and increased physical activity. | 1 | 1,306 | EG000 |
| Group 2 | Placebo | Participants were to receive once-weekly subcutaneous (s.c) injection of 0.25 mg Semaglutide placebo administered using a PDS290 pre-filled pen-injector with a 3 mL cartridge containing Semaglutide placebo 1.0 mg/mL or 3.0 mg/mL and followed a fixed-dose escalation regimen, with dose increases every 4 weeks (to doses of 0.5, 1.0, 1.7 and 2.4 mg/week), aiming at reaching the maintenance dose of 2.4 mg Semaglutide placebo after 16 weeks. Treatment was continued on the maintenance dose of 2.4 mg once weekly for an additional 52 weeks until week 68. The treatment was an adjunct to a reduced-calorie diet and increased physical activity. | 1 | 655 | EG001 |
