- NCT05514535

- Novo Nordisk A/S
- Brief Summary
This study compares semaglutide, together with a lower dose of insulin glargine, to a higher dose of insulin glargine in participants with type 2 diabetes. The study looks at how well the study medicines control blood glucose levels. Participants will either get semaglutide together with a lower dose of insulin glargine or a higher dose of insulin glargine. The study will last for about 47 weeks (approximately 11 months). Participants will have 9 clinic visits, 15 phone/video calls and 1 home visit. Participants will be asked to wear a sensor that measures their blood sugar all the time in 2 periods of 10 days during the study.

Group Intervention Description Insuline glargine U100 (titrated) Insuline glargine U100 (titrated) Participants will receive titrated insuline glargine U100 s.c. once-daily. Insulin glargine U100 dose will be adjusted based on the mean of three pre-breakfast SMPG values (target SMPG: 4.4-7.2 mmol/L). Insuline glargine U100 (reduced) + semaglutide Insuline glargine U100 (reduced) Participants will initially receive 0.25 milligrams (mg) once-weekly semaglutide subcutaneously (s.c.) and the dose will be gradually escalated to 2 mg as an add-on to dose-reduced insulin glargine s.c. given once-daily. Insulin glargine U100 will be reduced by 10 U at the initiation of semaglutide and then again at each semaglutide dose escalation. Insulin glargine dose will be adjusted based on the mean of three pre-breakfast self-measured plasma glucose (SMPG) values (target SMPG: 4.4-7.2 millimoles per litre (mmol/L)). Insuline glargine U100 (reduced) + semaglutide Semaglutide Participants will initially receive 0.25 milligrams (mg) once-weekly semaglutide subcutaneously (s.c.) and the dose will be gradually escalated to 2 mg as an add-on to dose-reduced insulin glargine s.c. given once-daily. Insulin glargine U100 will be reduced by 10 U at the initiation of semaglutide and then again at each semaglutide dose escalation. Insulin glargine dose will be adjusted based on the mean of three pre-breakfast self-measured plasma glucose (SMPG) values (target SMPG: 4.4-7.2 millimoles per litre (mmol/L)).
- Primary Outcome Measures
Name Time Method Change in Glycated Haemoglobin (HbA1c) From baseline (week 0) to end of treatment (week 40) Non-inferiority of semaglutide s.c. as add-on to dose-reduced insulin glargine to that of titrated insulin glargine will be assessed based on the clinically acceptable margin of 0.3 percentage (%) for the mean treatment difference in HbA1c. Measured as percentage.
- Secondary Outcome Measures
Name Time Method Relative Change in Daily Insulin Dose From baseline (week 0) to end of treatment (week 40) Measured as percentage
Number of Severe Hypoglycaemic Episodes (Level 3) From baseline (week 0) to end of treatment (week 40) Measured as number of episodes
Change in Score of Short Form 36 Version 2 (SF-36 v2) From baseline (week 0) to end of treatment (week 40) The SF-36 v2 will be used to measure differences in quality of life and mental wellbeing. The scores 0-100 (where higher scores indicated a better quality of life and mental wellbeing) from the SF-36 will be converted to a norm-based score using a T-score transformation in order to obtain a direct interpretation in relation to the distribution of the scores in the 1998 United States general population. Measured as score on a scale.
Participants Achieving: Insulin Dose Equal to 0 Units (Yes/No) At end of treatment (week 40) Measured as count of participants
Number of Clinically Significant Hypoglycaemic Episodes (Level 2) (Less Than 3.0 mmol/L (54 mg/dL), Confirmed by Blood Glucose Meter) or Severe Hypoglycaemic Episodes (Level 3) From baseline (week 0) to end of treatment (week 40) Measured as number of episodes
Participants Achieving All of The Following Targets: HbA1c Reduced From Baseline by At Least 0.3 %; Insulin Dose Reduced From Baseline; No Hypoglycaemic Episodes; No Weight Gain At end of treatment (week 40) No hypoglycaemic episodes defined as less than 3.9 mmol/L \[70 milligrams per decilitre (mg/dL)\] confirmed by Blood Glucose meter. Outcome measure measured as count of participants.
Change in Body Weight From baseline (week 0) to end of treatment (week 40) Measured as kilogram
Participants Achieving: Insulin Dose Reduced From Baseline by at Least 50 Percentage (Yes/No) At end of treatment (week 40) Measured as count of participants
Number of Clinically Significant Hypoglycaemic Episodes (Level 2) (Less Than 3.0 Millimoles Per Litre (mmol/L) [54 Milligrams Per Decilitre (mg/dL)] Confirmed by Blood Glucose Meter) From baseline (week 0) to end of treatment (week 40) Measured as number of episodes
Change in HbA1c From baseline (week 0) to end of treatment (week 40) Superiority of semaglutide s.c. as add-on to dose-reduced insulin glargine versus titrated insulin glargine will be assessed. Measured as percentage.
Score of Diabetes Treatment Satisfaction Questionnaire - Change Version (DTSQc) At end of treatment (week 40) The questionnaire has been designed to measure the change in the level of satisfaction with diabetes treatment regimens in participants with diabetes who have had a recent intervention. It consists of 8 questions, which are to be answered on a Likert scale from -3 to +3 (-3 = much less satisfied now to +3 = much more satisfied now), with 0 (midpoint), representing no change. Six questions are summed to produce a total treatment satisfaction score. The remaining two questions concern perceived frequency of hyperglycemia and perceived frequency of hypoglycemia, respectively. The DTSQc total treatment satisfaction score ranges from -18 to +18, with higher scores associated with greater treatment satisfaction. Measured as score on a scale.
Participants Achieving: HbA1c less than 7 Percentage (Yes/No) At end of treatment (week 40) Measured as count of participants
Change in Score of Diabetes Treatment Satisfaction Questionnaire - Status Version (DTSQs) From baseline (week 0) to end of treatment (week 40) The questionnaire has been designed to measure satisfaction with diabetes treatment regimens in participants with diabetes. The questionnaire contains 8 components and measures the treatment for diabetes (including insulin, tablets and/or diet) in terms of convenience, flexibility and general feelings regarding treatment. The value presented is the 'Treatment Satisfaction' summary score, which is the sum of 6 of the 8 items of the DTSQs questionnaire. Response options range from 6 (best case) to 0 (worst case). Total scores for treatment satisfaction range from 0-36. Higher scores indicate higher satisfaction. Measured as score on a scale.
