About this study
Official title: A 52 Week Study Comparing the Efficacy and Safety of Once Weekly IcoSema and Daily Insulin Glargine 100 Units/mL Combined With Insulin Aspart, Both Treatment Arms With or Without Oral Anti Diabetic Drugs, in Participants With Type 2 Diabetes Inadequately Controlled With Daily Basal Insulin. COMBINE 3
This study will compare the new medicine IcoSema, which is a combination of insulin icodec and semaglutide, taken once a week, to insulin glargine taken daily with insulin aspart in people with type 2 diabetes.The study will look at how well IcoSema controls blood sugar level in people with type 2 diabetes compared to insulin glargine taken with insulin aspart. Participants will either get IcoSema or insulin glargine taken with insulin aspart. Which treatment participants get is decided by chance. IcoSema is a new medicine that doctors cannot prescribe. Doctors can already prescribe insulin glargine and insulin aspart in many countries.
Participants will get IcoSema or insulin glargine together with insulin aspart. Participants must inject IcoSema once a week or inject insulin glargine once daily and insulin aspart 2-4 times a day. Participants will inject the medicines with a pen, which has a small needle, in a skin fold in the thigh, upper arm, or stomach. The study will last for about 1 year and 1 month. Participants will be asked to wear a sensor that measures participants blood sugar level all the time during an 8 week period at the beginning of the study and a 4 week period at the end of the study.
Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period.

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will compare the new medicine IcoSema, which is a combination of insulin icodec and semaglutide, taken once a week, to insulin glargine taken daily with insulin aspart in people with type 2 diabetes.The study will look at how well IcoSema controls blood sugar level in people with type 2 diabetes compared to insulin glargine taken with insulin aspart. Participants will either get IcoSema or insulin glargine taken with insulin aspart. Which treatment participants get is decided by chance. IcoSema is a new medicine that doctors cannot prescribe. Doctors can already prescribe insulin glargine and insulin aspart in many countries.
Participants will get IcoSema or insulin glargine together with insulin aspart. Participants must inject IcoSema once a week or inject insulin glargine once daily and insulin aspart 2-4 times a day. Participants will inject the medicines with a pen, which has a small needle, in a skin fold in the thigh, upper arm, or stomach. The study will last for about 1 year and 1 month. Participants will be asked to wear a sensor that measures participants blood sugar level all the time during an 8 week period at the beginning of the study and a 4 week period at the end of the study.
Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 14 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 182 sites in United States, India, Czechia, Japan, Malaysia and 9 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 HbA1c (time frame: From baseline week 0 (V2) to week 52 (V54)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05013229, which also lists 3 linked publications.
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 2 Dec 2025.
