What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
liraglutideDrug
Starting dose of 0.6 mg/day, with weekly dose escalations of 0.6 mg/day until the maintenance dose of 1.8 mg/day is reached. Administered subcutaneously (s.c., under the skin) once daily + metformin tablets (at least 1000 mg/day)
sitagliptinDrug
100 mg/day sitagliptin tablets once-daily + metformin (at least 1000 mg/day)

| Study group | Role | What they receive |
|---|---|---|

| Sitagliptin + metformin + liraglutide placebo | Experimental | Not described Receives: Drug: sitagliptin; Drug: placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in HbA1c (Glycosylated Haemoglobin)
Change from baseline in HbA1c was analysed after 26 weeks of treatment. Analysis population set: full analysis set (FAS); all randomised subjects receiving at least one dose of any of the trial products. Missing values were imputed using mixed model for repeated measurements (MMRM).
Measured: From baseline to week 26
Secondary outcomes (6)
Change in Body Weight
Change from baseline in body weight was analysed after 26 weeks of treatment. Analysis population set: FAS: all randomised subjects receiving at least one dose of any of the trial products. Missing values were imputed using MMRM.
Measured: From baseline to week 26
Change in Fasting Plasma Glucose
Change from baseline in fasting plasma glucose was analysed after 26 weeks of treatment. Missing values were imputed using MMRM.
Measured: From baseline to week 26
Change in Fasting Blood Lipids
Ratio to baseline in fasting blood lipids (total cholesterol, low density lipoprotein [LDL], very low density lipoprotein [VLDL], high density lipoprotein [HDL], triglycerides, and free fatty acids) were analysed after 26 weeks treatment. Missing values were imputed using MMRM. Here we are presenting ratio to baseline data.
Measured: From baseline to week 26
Change in Systolic Blood Pressure and Diastolic Blood Pressure
Change from baseline in systolic and diastolic blood pressure were analysed after 26 weeks of treatment. Missing values were imputed using MMRM.
Measured: From baseline to week 26
Subjects Who Achieve HbA1c Below 7.0% (53 mmol/Mol) (American Diabetes Association Target) (y/n)
Number of subjects who achieve HbA1c <7.0% were analysed after 26 weeks of treatment. Missing values were imputed using MMRM.
Measured: After 26 weeks of treatment
Number of Treatment Emergent Adverse Events (TEAEs)
A treatment emergent adverse event (TEAE) was defined as an event that had an onset date (or increase in severity) on or after the first day of exposure to randomised treatment and no later than seven days after the last day of randomised treatment. The number of TEAEs was recorded during 26 weeks of treatment plus one week follow-up period.
Measured: During 26 weeks of treatment plus one week follow-up period.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing liraglutide and sitagliptin in people with Diabetes and Diabetes Mellitus, Type 2, run by Novo Nordisk A/S at 106 sites in 7 countries.
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 4 inclusion and 12 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 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 106 sites in United States, Canada, Hungary, India, Israel and 2 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 1 Jul 2016). 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 HbA1c (Glycosylated Haemoglobin) (time frame: From baseline to week 26). 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 NCT01907854, which also lists 1 linked publication.
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 Oct 2018.
