Diabetes Mellitus, Type 2
Conditions
Brief summary
This study compares how three doses of semaglutide work in participants with type 2 diabetes (T2D) and overweight who are taking metformin. The study will look mainly at how well participant's blood sugar and participant's body weight are controlled when they are taking the study medicine at different doses. Participants will either get semaglutide \[2 milligrams (mg), 8 mg, or 16 mg\] or semaglutide placebo (a dummy medicine). Participants will take the study medicine with an injection pen called NovoPen®4. The injection pen is a medical tool with a needle used to inject the study medicine under the skin. The study will last for about 52 weeks. Participants will have 13 clinic visits and 4 phone calls.
Interventions
Semaglutide s.c. injection once-weekly for 40 weeks. Dose gradually increased over 24 weeks, followed by a 16 week maintenance period.
Semaglutide placebo s.c. injection once-weekly for 40 weeks. Dose gradually increased over 24 weeks, followed by a 16 week maintenance period.

Eligibility
Inclusion criteria
* Male or female. * Aged 18-64 years (both inclusive) at the time of signing informed consent. * Diagnosed with type 2 diabetes mellitus greater than equal to (≥) 180 days prior to the day of screening. * Glycosylated haemoglobin (HbA1c) of 7.0 - 10.5 percentage (%) \[53 - 91 millimoles per mole (mmol/mol)\] (both inclusive). * Body Mass Index (BMI) ≥ 27.0 kilograms per meter square (kg/m\^2). * Stable daily dose(s) ≥ 90 days prior to the day of screening of any metformin formulations.
Exclusion criteria
* Treatment with any medication for the indication of diabetes or obesity other than stated in the inclusion criteria within 90 days before screening.

| Change in Body Weight | Baseline (week 0) and End of treatment (week 40) | Change in body weight from baseline (week 0) to end of treatment (week 40) is presented. |
| Number of Treatment-emergent Adverse Events (TEAEs) | From baseline (week 0) up to end of study (week 49) | An adverse event (AE) is any untoward medical occurrence in a clinical study participant that is temporally associated with use of investigational medicinal products (IMP), whether or not considered related to IMP. AE can therefore be any unfavourable & unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with use of IMP. TEAE was defined as event that had onset date (or increase in severity) during on-treatment observation period. On treatment observation period data are presented. On-treatment observation period is defined as time points from first drug date until first date of end of data point sets (DPS1) or last administration of randomised treatment +63 days. DPS1 in trial is defined as all observed data points from randomisation until first date of end of study visit or date of death or date of withdrawal of informed consent or contact as defined by investigator for participants that are lost to follow up. |
| Number of Treatment-emergent Severe Hypoglycaemic Episodes | From baseline (week 0) up to end of study (week 49) | Number of treatment-emergent severe Hypoglycaemic episodes are presented. Severe hypoglycaemic episodes (level 3) were defined as episodes that were associated with severe cognitive impairment requiring external assistance for recovery. On treatment observation period data are presented. On-treatment oberservation period is defined as time points from first drug date until the first date of end of data point sets (DPS1) or last administration of randomised treatment +63 days. DPS1 in trial is defined as all observed data points from randomisation until the first date of end of study visit or date of death or date of withdrawal of informed consent or date of last contact as defined by investigator for participants that are lost to follow up. |

Number of Treatment-emergent Adverse Events (TEAEs)
An adverse event (AE) is any untoward medical occurrence in a clinical study participant that is temporally associated with use of investigational medicinal products (IMP), whether or not considered related to IMP. AE can therefore be any unfavourable & unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with use of IMP. TEAE was defined as event that had onset date (or increase in severity) during on-treatment observation period. On treatment observation period data are presented. On-treatment observation period is defined as time points from first drug date until first date of end of data point sets (DPS1) or last administration of randomised treatment +63 days. DPS1 in trial is defined as all observed data points from randomisation until first date of end of study visit or date of death or date of withdrawal of informed consent or contact as defined by investigator for participants that are lost to follow up.
Time frame: From baseline (week 0) up to end of study (week 49)
Population: Safety analysis set included all participants who are exposed to randomised treatment.
