Comparison of Two NN5401 Formulations Versus Insulin Glargine, All in Combination With Metformin in Subjects With Type 2 Diabetes

What Was Tested

In this phase 2 trial, researchers set out to test Insulin Glargine and Insulin Aspart.

This trial is conducted in Europe.

The aim of this trial is to compare two NN5401 (SIAC, insulin degludec/insulin aspart) formulations with each other and with insulin glargine, all in combination with metformin in insulin naive subjects with type 2 diabetes.

It had three arms (groups): Insulin glargine (active comparator), SIAC 30 (B) (experimental) and SIAC 45 (B) (experimental).

The registry classes the interventions as drug.

Who Took Part

178 actual participants took part.

It was open to people of any sex aged from 18 years up to 75 years.

Healthy volunteers were not accepted; participants needed the condition being studied.

Examples of who could join: Informed consent obtained before any trial-related activities. (Trial-related activities are any procedure that would not have been performed during normal management of the subject.). Body Mass Index (BMI), 25.0 - 37.0 kg/m\^2 (both inclusive).

The full record lists 5 inclusion and 4 exclusion criteria; among the exclusions: metformin contraindication according to local practice; thiazolidinedione (tzd) treatments within the previous three months prior to visit 1.

How the Study Was Run

The set-up was randomized, parallel-group and open-label.

The participants were allocated by chance, so the Insulin Glargine group and the comparison group should start out alike.

The Insulin Glargine group and the comparison group ran side by side rather than switching.

Everyone knew when Insulin Glargine was being given (open label), which is simpler to run but leaves more room for expectations to affect what is reported.

It started in 2008-01 with completion listed for 2008-07.

It ran at 28 sites in France (6), Germany (6), Norway (6), Romania (5) and Spain (5).

Its stated primary purpose is treatment.

What Was Measured

Researchers chose this as the main measure: Change in Glycosylated Haemoglobin (HbA1c) (time frame: Week 0, Week 16).

It also tracked 12 secondary outcomes, for example Change in Fasting Plasma Glucose (FPG), Mean of 9-point Self Measured Plasma Glucose Profile (SMPG), Rate of Treatment Emergent Adverse Events (AEs), Rate of Major and Minor Hypoglycaemic Episodes, Rate of Nocturnal Major and Minor Hypoglycaemic Episodes and Laboratory Safety Parameters (Biochemistry): Alanine Aminotransferase (ALAT).

What This Means in Plain Language

Put simply, this is a phase 2, randomized trial of Insulin Glargine and Insulin Aspart in 178 people.

The trial is marked completed; results are posted on the registry, and this page does not restate them.
