Trial to Evaluate Cardiovascular and Other Long-term Outcomes With Semaglutide in Subjects With Type 2 Diabetes

Phase 3

Completed

Conditions: Diabetes
Diabetes Mellitus, Type 2

Interventions: Drug: semaglutide
Drug: placebo

Registration Number: NCT01720446

Lead Sponsor: Novo Nordisk A/S

Brief Summary: 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.

Primary Outcome Measures

Name	Time	Method
Time From Randomisation to First Occurrence of a MACE, Defined as Cardiovascular Death, Non-fatal Myocardial Infarction, or Non-fatal Stroke	Time from randomisation up to end of follow-up (scheduled at week 109)	Percentage of subjects experiencing a first event of a major adverse cardiovascular event (MACE), defined as cardiovascular (CV) death, non-fatal myocardial infarction (MI), or non-fatal stroke.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline to Last Assessment in the Trial in Other Treatment Outcomes: Fasting Plasma Glucose	Week 0, up to week 104	Estimated mean change from baseline to last assessment in fasting plasma glucose in the trial during the treatment period.
Incidence During the Trial in Other Treatment Outcomes: Adverse Events	Weeks 0-109	Rates (event rate per 100 years of exposure) of treatment emergent adverse events.
Time From Randomisation to First Occurrence of an Expanded Composite Cardiovascular Outcome	Time from randomisation up to end of follow-up (scheduled at week 109)	Percentage of subjects experiencing first occurrence of an expanded composite CV outcome (defined as either MACE, revascularisation \[coronary and peripheral\], unstable angina requiring hospitalisation or hospitalisation for heart failure)
Time From Randomisation to Each Individual Component of the Expanded Composite Cardiovascular Outcome	Time from randomisation up to end of follow-up (scheduled at week 109)	Percentage of subjects experiencing an event onset for each individual component of the expanded composite cardiovascular outcomes (defined as either MACE, revascularisation \[coronary and peripheral\], unstable angina requiring hospitalisation or hospitalisation for heart failure).
Time From Randomisation to First Occurrence of All-cause Death, Non-fatal MI, or Non-fatal Stroke	Time from randomisation up to end of follow-up (scheduled at week 109)	Percentage of subjects experiencing a first occurrence of all-cause death, non-fatal MI, or non-fatal stroke.
Change From Baseline to Last Assessment in the Trial in Other Treatment Outcomes: Glycosylated Haemoglobin (HbA1c)	Week 0, up to week 104	Estimated mean change from baseline in glycosylated haemoglobin (HbA1c) to last assessment in the trial during the treatment period.
Change From Baseline to Last Assessment in the Trial in Other Treatment Outcomes: Urinary Albumin to Creatinine Ratio	Week 0, up to week 104	Estimated ratio to baseline in urinary albumin to creatinine ratio at week 104 during the treatment period.
Change From Baseline to Last Assessment in the Trial in Other Treatment Outcomes: Vital Signs (Pulse Rate)	Week 0, up to week 104	Estimated mean change from baseline to last assessment in the trial during the treatment period in vital signs (pulse rate).
Change From Baseline to Last Assessment in the Trial in Other Treatment Outcomes: Body Weight	Week 0, up to week 104	Estimated mean change from baseline to last assessment in body weight in the trial during the treatment period.
Change From Baseline to Last Assessment in the Trial in Other Treatment Outcomes: Lipid Profile	Week 0, up to week 104	Estimated ratio to baseline at week 104 during the treatment period in lipid profile (total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides).
Change From Baseline to Last Assessment in the Trial in Other Treatment Outcomes: Vital Signs	Week 0, up to week 104	Estimated mean change from baseline to last assessment in the trial during the treatment period in vital signs (diastolic blood pressure and systolic blood pressure).
Incidence During the Trial in Other Treatment Outcomes: Hypoglycaemic Events	Week 0 - 109	Rates (event rate per 100 exposure years) of severe or blood glucose confirmed symptomatic hypoglycaemia defned as an episode that was severe according to the American diabetic association (ADA) classification or blood glucose (BG) confirmed by a PG value \<3.1 mmol/L (56 mg/dL) with symptoms consistent with hypoglycaemia.
