Tesamorelin and Liver Fat in HIV: What the Trial Found

A small randomized trial found lower liver fat with tesamorelin in adults with HIV and fatty liver. The result does not establish a liver-disease indication or long-term clinical benefit.

What did the study test?

The 2019 randomized, double-blind study enrolled 61 adults with HIV and fatty liver; 30 received tesamorelin and 30 received placebo. Its primary endpoint was change in hepatic fat fraction measured with proton magnetic resonance spectroscopy over 12 months. This was a liver-fat study in a specific population. (Stanley et al., 2019)

Results and their limits

Tesamorelin reduced hepatic fat fraction by 4.1 percentage points more than placebo (95% CI, 0.7 to 7.6 points greater reduction). At 12 months, 35% of the tesamorelin group versus 4% of the placebo group had hepatic fat fraction below 5%. Glucose measures did not differ significantly between groups at that time point. These results do not establish improved survival, prevention of liver failure or long-term safety. (Trial report)

Evidence grade: low for the measured liver-fat endpoint in this HIV population. The small study does not establish a broadly effective treatment for fatty liver, and its authors called for further study of long-term liver histology. (Trial report)

How this differs from the approved use

The FDA indication concerns excess abdominal fat in adults with HIV-associated lipodystrophy. It is not a fatty-liver indication or general weight-loss approval. The label also identifies glucose intolerance, elevated IGF-1 and other risks; long-term cardiovascular safety remains unestablished. (FDA prescribing information, current label)
