Efficacy and Safety of Liraglutide on Body Weight in Obese Subjects or Overweight Subjects With Co-morbidities

Efficacy and Safety of Liraglutide on Body Weight in Non-diabetic Obese Subjects or Overweight Subjects With Co-morbidities: A Randomised, Double-blind, Placebo Controlled, Parallel Group, Multi-centre, 28-week Trial

We performed a multicenter, randomized, double-blind, placebo-controlled 28-week trial. 300 non-diabetic obese subjects or overweight subjects with co-morbidities were randomly assigned. Eligible participants were randomized 2:1 to once-daily subcutaneous injections of either liraglutide or placebo. The primary outcome is to investigate the safety, tolerability from baseline to end of treatment.

Study Overview

• Status: Unknown
• Conditions: Obesity
• Intervention / Treatment: Drug: Liraglutide; Drug: placebo

Detailed Description

We performed a multicenter, randomized, double-blind, placebo-controlled 28-week trial. 300 individuals (18-75 years of age, body-mass index ≥30 kg/m2 or BMI 27-30kg/m2 accompanied by at least one weight-related complication (treated or untreated hypertension, dyslipidemia, pre-diabetes)) were randomly assigned. All the patients provided written informed consent before participation. Key exclusion criteria were type 1 or 2 diabetes, the use of medications that cause clinically significant weight gain or loss, previous bariatric surgery, a history of pancreatitis, a history of major depressive or other severe psychiatric disorders, and a family or personal history of multiple endocrine neoplasia type 2 or familial medullary thyroid carcinoma. Eligible participants were randomized 2:1 to once-daily subcutaneous injections of either liraglutide or placebo using a computer-generated, centrally administered procedure. Patients, investigators, and the sponsor were unaware of the study-group assignments. The primary endpoint was change in bodyweight during the 28 weeks of the study in the intention-to-treat population. The proportion of people losing more than 5% of baseline weight was also assessed. Secondary efficacy endpoints included the proportion of people losing more than 10% of baseline weight was also assessed, change in waist circumference, hip circumference, WHR, systolic and diastolic blood pressure, fasting lipids (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides), glucose metabolism parameters (fasting plasma glucose, 2-hour post-challenge plasma glucose and glycosylated haemoglobin [HbA1c]).
