A Research Study to Compare Semaglutide to Insulin Aspart, When Taken Together With Metformin and Insulin Glargine, in People With Type 2 Diabetes

First event per 100 years of exposure time for first EAC confirmed severe hypoglycaemic episodes from randomization (week 0) to week 52 are presented. As per 2013 ADA criteria severe hypoglycaemic episodes were episodes with plasma glucose (PG) less than or equal to (<=) 3.9 millimoles per liter (mmol/L) (70 milligrams per deciliter (mg/dL)). EAC confirmed-severe hypoglycaemia was an episode requiring assistance of another person to actively administer carbohydrate, glucagon or take other corrective actions. Data is reported for 'on-treatment' observation period: from the date of first dose of trial product (week 0) to the last date on trial product with a visit window of +7 days (week 52).

All 10 scores range from 5.79-70.42 . Higher scores indicated a better health state. Change from baseline in SF-36v2, 2 summary and 8 domains scores at week 52 is presented. Data is reported for 'on-treatment' observation period: from date of first dose of trial product (week 0) to last date on trial product with a visit window of +7 days (week 52).

The DQLCTQ-R questionnaire was used to assess participants' HRQoL. The DQLCTQ-R questionnaire contains 57 items and measures and provide scores for the 8 domains (physical function, energy or fatigue, health distress, mental health, satisfaction, treatment satisfaction, treatment flexibility and frequency of symptoms). The 8 domain scores related to DQLCTQ-R are measured on a scale from 0-100. For all scores, higher values indicated better health status. Change from baseline in DQLCTQ-R 8 domain scores at week 52 is presented. Data is reported for 'on-treatment' observation period: from the date of first dose of trial product (week 0) to the last date on trial product with a visit window of +7 days (week 52).
