A Trial Investigating the Pharmacodynamic Properties of NN1218 in Subjects With Type 1 Diabetes

What Was Tested

This registered phase 1 trial tested Insulin Aspart.

This trial is conducted in Europe.

It had three arms (groups): Formulation A (experimental), Formulation B (experimental) and Insulin Aspart (active comparator).

The registry classes the interventions as drug.

Who Took Part

Enrollment: 52 actual participants took part.

It was open to people of any sex aged from 18 years up to 64 years.

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

Examples of who could join: Type 1 diabetes mellitus for more than 12 months. Treated with multiple daily insulin injections or continuous subcutaneous insulin infusion for more than 12 months. Body mass index (BMI) between 18.0-28.0 kg/m\^2 (both inclusive).

The full record lists 3 inclusion and 3 exclusion criteria; among the exclusions: smoker (defined as a subject who is smoking more than 5 cigarettes or the equivalent per day); not able or willing to refrain from smoking and use of nicotine substitute products during the inpatient period.

How the Study Was Run

It was run as a randomized, crossover and double-blind study.

Because people in this Insulin Aspart study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Each person switched between Insulin Aspart and the comparison at some point, usually with a gap in between.

Blinding on both sides kept the participants and researchers unaware of who received Insulin Aspart.

Those kept unaware of assignments: participant and investigator.

It started in 2012-06-11 with completion listed for 2012-09-07.

It ran at 1 site in Germany.

Its stated primary purpose is treatment.

What Was Measured

The main thing measured (primary outcome): Area under the glucose infusion rate curve (time frame: From 0 to 2 hours).

It also tracked 3 secondary outcomes, for example Area under the glucose infusion rate curve, Maximum glucose infusion rate and Time to maximum glucose infusion rate.

What This Means in Plain Language

Put simply, this is a phase 1, randomized trial of Insulin Aspart in 52 people.

The trial is marked completed; no results are posted to the registry yet, so nothing here describes outcomes.
