What This Study Did, in Plain Language

What Was Tested

The trial (phase 4) is built around NPH Insulin (isophane).

To compare the short and long term effects of inhibitor of the DPP-IV enzyme, sitagliptin , with bedtime NPH insulin in patients with T2D inadequately controlled with sulphonylurea plus biguanide: effects on beta cell function and on metabolic profile.

It had two arms (groups): sitagliptin (active comparator) and NPH insulin (active comparator).

The registry classes the interventions as drug.

More on the Plan

Effects on beta cell function and on metabolic profile were analyzed.

Measurements of HbA1c, metabolic and hormonal profile at fasting and post-meal (every 30 minutes for 4 hours) will be evaluated before and after 6 months (short term) and 12 months (long term) of adding sitagliptin or NPH insulin.

Who Took Part

Enrollment: 40 actual participants took part.

It was open to people of any sex aged from 35 years up to 70 years.

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

Examples of who could join: Outpatients with T2D inadequately controlled with metformin plus glyburide. Body mass index \< 35 kg/m2.

The full record lists 3 inclusion and 12 exclusion criteria; among the exclusions: heart failure; respiratory failure; uncontrolled hypertension.

How the Study Was Run

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

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

The NPH Insulin (isophane) group and the comparison group ran side by side rather than switching.

Being open-label, the NPH Insulin (isophane) study did not mask who received what.

It started in 2010-01 with completion listed for 2012-01.

It ran at 1 site in Brazil.

Its stated primary purpose is treatment.

What This Means in Plain Language

Put simply, this is a phase 4, randomized trial of NPH Insulin (isophane) in 40 people.

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

Our Notes on the Compound

NPH Insulin (isophane): An intermediate-acting insulin made by combining insulin with protamine; also called isophane or NPH insulin (Humulin N, Novolin N).
