The Effect of Simple Insulin Detemir Titration, Metformin Plus Liraglutide Compared to Simple Insulin Detemir Titration Plus Insulin Aspart and Metformin for Type 2 Diabetes With Very Elevated HbA1c - The SIMPLE Study: A 26 Week, Randomized, Open Label, Parallel-group, Intention to Treat Study

The aim of this clinical trial is to assess and compare the effect of insulin detemir in combination with liraglutide and metformin versus insulin detemir in combination with insulin aspart and metformin in subjects with very uncontrolled Type 2 Diabetes (A1c > 10%).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of this study is to compare a GLP-1 plus basal insulin and metformin treatment regimen to a basal-bolus plus metformin treatment regimen in patients with very uncontrolled (HbA1c>10%) type 2 diabetes. The investigators will compare the two regimens with respect to efficacy in improving glycemic control, rate of hypoglycemia, change in weight, effect on patient quality of life, treatment burden, physician time, as well as healthcare related cost. The investigators hypothesize that at 26 weeks from randomization the two treatment regimens will have similar percentage of patients reaching A1c levels <7.0%, while more patients on the GLP-1 plus basal insulin strategy will achieve the composite end point of A1c levels <7.0% without severe hypoglycemia or significant weight gain.

Eligibility Criteria

Eligibility Criteria

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Change From Randomization in A1c at Week 26
Time Frame: Baseline and Week 26
Change in glycosylated Hemoglobin A1c (A1c) from randomization to 26 weeks of therapy
Baseline and Week 26

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Composite End-point
Time Frame: Week 0 (Randomization) , Week 26
Percentage of participants with glycosylated Hemoglobin A1c (A1c)<8% AND no documented severe hypoglycemia (<56 mg/dL) during the study AND no significant weight gain (>3% from baseline)

Diabetes Quality of Life (DQOL) questionnaires will be completed by the patient at the randomization and end-of study visits. ALL D-QOL domains are scored on a 1-5 scale, with a lower number representing better quality of life or treatment satisfaction. Outcome reported is difference between mean baseline and mean Week 26 score.
