Combinatorial Therapy for Peristent Type 2 Diabetes After Gastric Banding
LIRAGLUTIDE AND ORLISTAT TREATMENT FOR PERSISTENT TYPE 2 DIABETES AFTER GASTRIC BANDING: A PILOT STUDY
Study Overview

Intervention / Treatment
Detailed Description
Liraglutide and Orlistat improve glycemic control by increasing glucagon-like-peptide-1 (GLP-1) response and fat malabsorption, respectively but do not reverse type 2 diabetes. Roux-en-y gastric bypass (RYGB) surgery reverses type 2 diabetes 84% of the time while the less invasive, reversible laparoscopic adjustable gastric banding (LAGB) procedure reverses type 2 diabetes 48% of the time.
Decreased caloric intake occurs after RYGB and LAGB but increased post-prandial GLP-1 response and fat malabsorption only occur after RYGB. Since FDA-approved agents Liraglutide and Orlistat increase GLP-1 response and fat malabsorption, respectively, it is of significant clinical interest to determine if addition of Liraglutide and/or Orlistat can improve type 2 diabetes remission rates in the 52% of patients who have not achieved diabetes reversal after gastric banding.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Liraglutide only
|
Liraglutide will be started at 0.6 mg injected subcutaneously daily for 1 week and then increased as tolerated to 1.2 mg and then a 1.8 mg daily.
|
Active Comparator: Orlistat only
|
Orlistat will be started initially at a dose of 60 mg taken with the evening meal.
Additional doses will be added at breakfast or lunch every 1-2 weeks as tolerated.
The patient will be advised to skip drug dosing if little or no fat is contained in the meal.
Target dose will 60 mg three times a day and the patients will be advised to take a multivitamin 2 hours before or after Orlistat addition to ensure adequate nutrition.
|
Active Comparator: Liraglutide + Orlistat
|
Liraglutide will be started at 0.6 mg injected subcutaneously daily for 1 week and then increased as tolerated to 1.2 mg and then a 1.8 mg daily.
Patients not tolerating a higher dose will be allowed to remain on the lower dose as long they tolerate the lower.
Following titration of Liraglutide to a maximum tolerated dose, Orlistat will be started initially at a dose of 60 mg taken with evening meal.
Additional doses will be added at breakfast or lunch every 1-2 weeks as tolerated.
The patient will be advised to skip drug dosing if little or no fat is contained in the meal.
Target dose will 60 mg three times a day.
