Liraglutide in the Treatment of Type 1 Diabetes Mellitus

What this study is testing ClinicalTrials.gov NCT01722266 ↗

Description as written by the study sponsor.

Hypothesis 1: Treatment with Liraglutide in patients with type 1 diabetes decreases fasting, postprandial and the overall mean glucose concentrations. Aim 1.1: To compare the mean fasting, the mean weekly glucose and the standard deviation of weekly blood glucose concentrations as recorded by continuous glucose monitoring prior to and following 6 weeks and 12 weeks of treatment with 0.6, 1.2 and 1.8 mg of liraglutide daily. In addition, the time spent at glucose concentrations \>150 and 200mg/dl and \<70 and \<40 mg/dl will also be compared. Aim 1.2: To compare the postprandial glucose concentrations following a test meal before and after 12 weeks of treatment with 0.6, 1.2 and 1.8 mg of liraglutide daily. Glucose concentrations will be measured as areas under the curve for the data obtained from the meal challenge. Aim 1.3: To compare HbA1c levels(glycated hemoglobin) before and after 12 weeks of treatment with 0.6, 1.2 and 1.8 mg of liraglutide daily Hypothesis 2: Treatment with Liraglutide in patients with type 1 diabetes decreases postprandial glucagon concentrations and increases postprandial C-peptide concentrations. Aim 2.1: To compare fasting and postprandial glucagon and C-peptide concentrations following a test meal before and after 12 weeks of treatment with 0.6, 1.2 and 1.8 mg of liraglutide daily. Hypothesis 3: Treatment with Liraglutide in patients with type 1 diabetes delays gastric emptying. Aim 3.1: To compare the gastric emptying as measured by acetaminophen absorption before and after 12 weeks of treatment with 0.6, 1.2 and 1.8 mg of liraglutide daily.

Treatments tested

• Liraglutide also known as Victoza Drug

  Patients randomized to 1.2 mg of liraglutide : They will start liraglutide 0.6 mg sc once daily for one week and will increase the dose to 1.2 mg sc once daily thereafter. Patients randomized to 1.8 mg of liraglutide: They will start liraglutide 0.6 mg sc once daily for one week; will increase to 1.2 mg sc once daily for second week and will stay on 1.8 mg of liraglutide from third week onwards.

• Placebo Drug

  Patients randomized to 1.2 mg of placebo: They will start placebo 0.6 mg sc once daily for one week and then increase to 1.2 mg once daily thereafter. Patients randomized to 1.8 mg of placebo: They will start placebo 0.6 mg sc once daily for one week; increase to 1.2 mg sc once daily for second week and then to 1.8 mg sc once daily from third week onwards.
