About this study
Official title: Efficacy and Safety of Once-weekly Semaglutide S.C. 2.0 mg as Add-on to Dose-reduced Insulin Glargine vs Titrated Insulin Glargine in Participants With Type 2 Diabetes and Overweight
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.
- Conditions
- Diabetes Mellitus, Type 2, Obesity
- Being tested
- Semaglutide, Insuline glargine U100 (reduced), Insuline glargine U100 (titrated)
- Medical subject headings
- Diabetes Mellitus, Type 2, Obesity
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SemaglutideDrug
Participants will receive once-weekly semaglutide s.c. for 40 weeks. Semaglutide 0.25 mg will be given at week 0 and then the dose will be escalated at weeks 4, 8 and 12 to 0.5 mg, 1 mg, 2 mg respectively.
Insuline glargine U100 (reduced)Drug
Participants will receive insulin glargine U100 s.c. once-daily. Insulin glargine dose will be reduced by 10 U at initiation of semaglutide and then again at each semaglutide dose escalation up to 40 weeks. The 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 (titrated)Drug
Participants will receive titrated insulin glargine U100 s.c. once-daily up to 40 weeks. The dose will be adjusted based on the mean of three pre-breakfast SMPG values (target SMPG: 4.4-7.2 mmol/L).
| Study group | Role | What they receive |
|---|---|---|
| Insuline glargine U100 (reduced) + semaglutide | Experimental | 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)). Receives: Drug: Semaglutide; Drug: Insuline glargine U100 (reduced) |
| Insuline glargine U100 (titrated) | Active comparator | 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). Receives: Drug: Insuline glargine U100 (titrated) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Glycated Haemoglobin (HbA1c) [Noninferiority]
Change in HbA1c (Noninferiority) from baseline (Week 0) to end of treatment (Week 40) were reported. Here noninferiority was assessed based on the clinically acceptable margin of 0.3%-point for the mean treatment difference in HbA1c.
Measured: From baseline (week 0) to end of treatment (week 40)
Secondary outcomes (13)
Change in Body Weight
Change in body weight from baseline (Week 0) to end of treatment (Week 40) were reported. Body weight was measured in unit 'Kilogram (kg)'.
Measured: From baseline (week 0) to end of treatment (week 40)
Percentage Change in Daily Insulin Dose
Percentage change in daily insulin dose from baseline (Week 0) to end of treatment (Week 40) were reported. Percentage change from baseline to week 40 in insulin dose (%) was calculated as: ([insulin dose at week 40] - [insulin dose at baseline]) / [insulin dose at baseline] × 100.
Measured: From baseline (week 0) to end of treatment (week 40)
Change in Glycated Haemoglobin (HbA1c ) [Superiority]
Change in HbA1c (Superiority) from baseline (Week 0) to end of treatment (Week 40) were reported.
Measured: From baseline (week 0) to end of treatment (week 40)
Score of Diabetes Treatment Satisfaction Questionnaire - Change Version (DTSQc)
Score of Diabetes Treatment Satisfaction Questionnaire - change version (DTSQc) at end of treatment (week 40) were reported. The DTSQc provided a measure of how satisfied participants were with their current diabetes treatment compared with previous treatment. It consisted of 8 questions, which were 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. Out of 8 questions, 6 questions related to treatment satisfaction were summed to produce a total score. The DTSQc total treatment satisfaction score ranged from -18 to +18, with higher scores associated with greater treatment satisfaction.
Measured: At end of treatment (week 40)
Number of Participants Achieving Insulin Dose = 0 Units/mL (U)
Number of participants achieving Insulin dose = 0 U at the end of treatment (Week 40) were reported.
Measured: At end of treatment (week 40)
Number of Participants Achieving Insulin Dose Reduced From Baseline by at Least 50%
Number of participants achieving Insulin dose reduced from baseline by at least 50% by end pf treatment (Week 40) were reported.
Measured: At end of treatment (week 40)
Number of Participants Achieving HbA1c Less Than (<) 7%

SF-36 is self-administered questionnaire that measures each of following 8 health domains: physical functioning, role limitations due to physical problems (role-physical), social functioning, bodily pain, mental health, role limitations due to emotional problems (role-emotional), vitality, and general health perception. There are also 2 component scores derived from the 8 subscale scores: mental component summary and physical component summary. Physical component summary contains physical functioning, role-physical, bodily pain and general health and mental component summary contain vitality, social functioning, role-emotional and mental health. Each SF-36 domain and component summary score ranges from 0 to 100, higher scores reflect better participant health status. A positive change score indicates an improvement since baseline.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

| Arm | Type | Receives |
|---|---|---|
| Insuline glargine U100 (reduced) + semaglutide | Experimental | Drug: Semaglutide, Drug: 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 (titrated) | Active comparator | Drug: 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). |

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 11 May 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Glycated Haemoglobin (HbA1c) [Noninferiority] (time frame: From baseline (week 0) to end of treatment (week 40)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 May 2026.
