Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

This trial is conducted globally. The aim of the trial is to evaluate cardiovascular and other long-term outcomes with semaglutide in subjects with type 2 diabetes. The trial is event-driven, i.e. the maximum trial duration (up to max. 148 weeks) will depend on the accrual of major adverse cardiovascular events (MACE) in this trial and the remaining research programme. The incidence of MACE will be monitored throughout the trial which will be terminated according to plan when pre-specified stopping criteria are met.

Adverse events, as posted

Adverse events as posted: participants affected out of participants at risk, by group
GroupDeathsSerious eventsOther events
Semaglutide 0.5 mgSubjects received once-weekly dose of semaglutide 0.5 mg as an add-on to their standard-of-care treatment. Injections were administered subcutaneously in the thigh, abdomen or upper arm, at any time of day irrespective of meals. The injections were to be administered on the same weekday during the trial. Semaglutide was initiated at a dose of 0.25 mg and was escalated (doubled) to 0.5 mg after 4 weeks. Hence the target dose of 0.5 mg was achieved after 4 weeks of treatment. Each subject was treated for 104 weeks.–289 / 826573 / 826
Semaglutide 1.0 mgSubjects received once-weekly dose of semaglutide 1.0 mg as an add-on to their standard-of-care treatment. Injections were administered subcutaneously in the thigh, abdomen or upper arm, at any time of day irrespective of meals. The injections were to be administered on the same weekday during the trial. Semaglutide was initiated at a dose of 0.25 mg and was escalated (doubled) to 0.5 mg after 4 weeks. Hence the target dose of 1.0 mg was achieved after 8 weeks of treatment. Each subject was treated for 104 weeks.–276 / 822587 / 822
Placebo 0.5 mgSubjects received once-weekly dose of placebo 0.5 mg as an add-on to their standard-of-care treatment. Injections were administered subcutaneously in the thigh, abdomen or upper arm, at any time of day irrespective of meals. The injections were to be administered on the same weekday during the trial. Placebo was initiated at a dose of 0.25 mg and was escalated (doubled) to 0.5 mg after 4 weeks. Hence the target dose of 0.5 mg was achieved after 4 weeks of treatment. Each subject was treated for 104 weeks.–329 / 824547 / 824
Placebo 1.0 mgSubjects received once-weekly dose of placebo 1.0 mg as an add-on to their standard-of-care treatment. Injections were administered subcutaneously in the thigh, abdomen or upper arm, at any time of day irrespective of meals. The injections were to be administered on the same weekday during the trial. Placebo was initiated at a dose of 0.25 mg and was escalated (doubled) to 0.5 mg after 4 weeks. Hence the target dose of 1.0 mg was achieved after 8 weeks of treatment.
