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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Summary
Brief summary
This trial is conducted in Asia, Europe, Oceania and South America. The aim of this clinical trial is to generate data demonstrating how to intensify diabetes treatment using BIAsp 30 (biphasic insulin aspart 30) by adding or substituting BIAsp 30 to sitagliptin in various regimens for type 2 patients inadequately controlled on sitagliptin and metformin (with or without other oral anti-diabetic drugs (OADs)).

The trial is conducted as a phase 4 trial in the majority of the participating countries. However, in some countries the trial is conducted as phase 3b.
