简要总结
This study compares the effect on blood sugar levels of two medicines: insulin degludec and insulin glargine in people with type 2 diabetes. Participants will be treated with insulin degludec and insulin glargine during two different periods. Which treatment participants get first is decided by chance. Both medicines are approved for use in humans and available on the market. They can already be prescribed by participants' doctors. Participants will get pre-filled insulin pens to inject these insulins with. The study will last for about 41 weeks. Participants will visit the clinic 13 times and have 27 phone calls with the study doctor or study staff. At 12 of the clinic visits they will take blood samples. In order to evaluate the changes in participants' blood sugar level over time, participants will be asked to wear a small (35 millimetres (mm) x 5 mm) sensor on the back of participants' upper arm 3 times during the study. Each time participants must wear the sensor for 2 weeks. This sensor is called FreeStyle Libre Pro®. It has a very small tip which is 0.4 mm thick and is inserted 5 mm under participants' skin. Please note that participants will not be able to see the sensor readings while wearing it. The study doctor will show participants the readings when participants return to the clinic. Participants will be asked to fill in a diary in between visits. Participants will have contact with the study doctor or study staff each week. This is to adjust the dose of participants' study medicines and to ensure that participants are well. Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.

结局指标
主要结局
Percentage of Time Spent in Glycaemic Target Range 70-180 mg/dL (3.9-10.0 mmol/L) Both Inclusive, Using Flash Glucose Monitoring (FGM)
时间窗: During the 2-week maintenance period: weeks 16-17 (period-1) and weeks 34-35 (period-2)
The percentage of time spent in glycaemic target range was calculated as the number of recorded measurements in glycaemic target range (70-180 milligrams per deciliter \[mg/dL\] (3.9-10.0 millimoles per litre \[mmol/L\]), both inclusive) divided by the total number of recorded measurements. The endpoint is based on data recorded by FGM system. It was required that at least 70% of the planned FGM measurements during weeks 16-17 and weeks 34-35 were available for endpoint data to be included in the analysis.
次要结局
- Time Spent in Tight Glycaemic Target Range 70-140 mg/dL (3.9-7.8 mmol/L) Both Inclusive, Using Flash Glucose Monitoring(During the 2-week maintenance period: weeks 16-17 (period-1) and weeks 34-35 (period-2).)
- Level of Glycated Haemoglobin (HbA1c) - Percentage(After the 2-week maintenance period: weeks 16-17 (period-1) and weeks 34-35 (period-2).)
- Mean Glucose Levels Using Flash Glucose Monitoring (FGM)(During the 2-week maintenance period: weeks 16-17 (period-1) and weeks 34-35 (period-2).)
- Time Spent in Nocturnal Glycaemic Target Range 70-140 mg/dL (3.9-7.8 mmol/L) Both Inclusive, in the Nocturnal Period (00:01 am - 05:59 am Both Inclusive) Using Flash Glucose Monitoring(During the 2-week maintenance period: weeks 16-17 (period-1) and weeks 34-35 (period-2).)
