Awards & highlights


This trial is investigating whether a drug called tesamorelin, which helps the body produce growth hormone, can reduce the amount of fat in the liver and improve liver inflammation in people with obesity and nonalcoholic fatty liver disease.

Who is the study for?
This trial is for men and women aged 18-65 with obesity-related fatty liver disease (NAFLD), without cirrhosis, significant alcohol use, or diabetes. Participants must have a BMI ≥30kg/m2 (or ≥25kg/m2 if they have steatohepatitis), confirmed liver fat issues but not on certain medications like growth hormones or systemic corticosteroids recently.Check my eligibility
What is being tested?
The study tests whether tesamorelin, a drug that stimulates the release of growth hormone, can reduce liver fat and inflammation in obese individuals with NAFLD. It's compared to a placebo in this randomized trial to see if it improves cardiovascular risks associated with fatty liver disease.See study design
What are the potential side effects?
Tesamorelin may cause reactions at the injection site, joint pain, swelling in hands or feet, muscle discomfort, and possible increases in blood sugar levels. As it affects hormone levels, patients might experience other hormonal changes.
