A Research Study to Compare the Effect of Insulin Degludec and Insulin Glargine on Blood Sugar Levels in People With Type 2 Diabetes - the SWITCH PRO Study

Completed · Phase 4

Conditions studied: Diabetes Mellitus, Type 2

In brief

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.

• Treated with any basal insulin greater than or equal to 90 days prior to the day of screening with or without any of the following anti-diabetic drugs:

You may not qualify if…

However, intermittent bolus insulin treatment for periods of no longer than 14 days are permitted prior to the day of screening
• Anticipated initiation or change in concomitant medications known to affect weight or glucose metabolism (e.g., treatment with orlistat, thyroid hormones, or corticosteroids)
• Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Verified by a pharmacologically pupil-dilated fundus examination performed by an ophthalmologist or another suitably qualified health care provider within the past 90 days prior to screening or in the period between screening and run-in
