Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Drugs - insulin degludec
Treatment: Drugs - liraglutide

Experimental: IDeg -

Experimental: IDegLira -

Experimental: Lira -


Treatment: Drugs: insulin degludec/liraglutide
Insulin degludec/liraglutide treatment will be initiated and titrated (individually adjusted) twice weekly according to the mean self measured plasma glucose (SMPG) (fasting). Insulin degludec/liraglutide is injected subcutaneously (under the skin) once daily.

Treatment: Drugs: insulin degludec
Insulin degludec treatment will be initiated with 10 U and titrated (individually adjusted) twice weekly according to the mean SMPG (fasting). Insulin degludec is injected subcutaneously (under the skin) once daily.

Treatment: Drugs: liraglutide
Liraglutide will be started with 0.6 mg and subsequent 0.6 mg weekly dose escalation to 1.8 mg. Liraglutide dose of 1.8 mg/day will be continued for the remaining part of the trial. Liraglutide is injected subcutaneously (under the skin) once daily.

Summary
Brief summary
This trial is conducted globally. The aim of this trial is to compare the efficacy and safety of insulin degludec/liraglutide (IDegLira) versus insulin degludec (IDeg) and liraglutide (Lira) in subjects with type 2 diabetes. Subjects are to continue their pre-trial treatment with metformin or metformin + pioglitazone throughout the entire trial.
