a research study in people with type 2 diabetes to compare two types of insulin: insulin 287 and insulin glargine

Conditions: Diabetes Mellitus, Type 2

Summary: this study compares insulin 287 (a possible new medicine) to insulin glargine (a medicine doctors can already prescribe) in people with type 2 diabetes. different ways of switching from the insulin which the participants are already on to insulin 287 are also compared. this is done to find the best way to switch to insulin 287. the participants will either get insulin 287 that they will have to inject once a week or insulin glargine that they will have to inject once a day. which treatment any participant gets is decided by chance. the study will last for about 5 months (23 weeks). the participants will have 14 clinic visits and 6 phone calls with the study doctor. at 3 of the clinic visits participants will be asked not to eat or drink anything (except for water) in the last 8 hours before the visit. during the study, the doctor will ask the participants to: 1) measure their blood sugar every day with a blood sugar meter using a finger prick; 2) write down different information in a diary daily and return this to their study doctor. 3) wear a medical device (sensor) that measures the participants blood sugar all the time for 18 weeks (about 4 months) during the study.
