Investigating ALN-HSD for MASH with Genetic Risk

This study is looking at an investigational drug called ALN-HSD to treat Metabolic Dysfunction-Associated Steatohepatitis (MASH) in adults. MASH is a chronic liver disease where fat buildup causes inflammation and scarring (fibrosis) in the liver, which can lead to serious liver problems. This study is for people aged 18 to 75 who have MASH with moderate to severe scarring (F2 or F3) and a specific genetic risk. Participants will receive either ALN-HSD or a placebo (an inactive substance). The main goal is to see if ALN-HSD can reduce liver scarring over 52 weeks.

Study design
This interventional study plans to enroll 120 participants. It compares ALN-HSD to a placebo to see its effects.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint is measured at week 52, suggesting participants will be followed for at least this duration.
