Directions for use will be given together with trial products. The possible doses of semaglutide are 0.25 mg, 0.50 mg and 1.0 mg. The initial weekly dose will be 0.25 mg for four weeks, then 0.5 mg for four weeks and then 1.0 mg for the remaining treatment period. Patients who, due to adverse events, do not tolerate up-titration to 1.0 mg semaglutide will remain on 0.5 mg once-weekly. The injection is administered subcutaneously once-weekly. Placebo: The semaglutide placebo pens contain “XX-vehicle” (no active drug) and are administered in the same way and volume as semaglutide. The semaglutide placebo is specially packed for this study and will be used in the study only. The initial weekly dose will be 0.25 mg for four weeks, then 0.5 mg for four weeks and then 1.0 mg for the remaining treatment period. Patients who, due to adverse events, do not tolerate up-titration to 1.0 mg semaglutide placebo will remain on 0.5 mg once-weekly. The injection is administered once-weekly. |
