ALN-CIDEB in adults with MASLD to see if it helps the liver
Official title: A Phase 3, Randomized, Double-blind, Placebo-controlled Trial of ALN-CIDEB in Adults With Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)
Run by Regeneron Pharmaceuticals · NCT07854782 · Data updated 2026-11-12
This study tests whether ALN-CIDEB can help adults with MASLD and its liver damage compared to placebo.

Is this trial a fit for you?
✓Likely a good fit
Adults with MASLD and a liver stiffness measurement between 6 and 20 kPa who do not have other significant liver diseases and who have no recent or planned GLP-1 receptor agonist or related therapies during the treatment period.
✕Probably not a fit
Patients with other liver diseases, very high liver stiffness outside the specified range, a history of liver transplantation, or recent drug-induced liver injury may not benefit from this therapy.

What this trial studies
This Phase 3 interventional study evaluates ALN-CIDEB versus placebo in adults diagnosed with MASLD, a fatty liver condition that can lead to scarring and inflammation. The trial will assess safety and how well the drug affects liver fat, liver injury markers, and fibrosis progression. Participants will receive the study drug or placebo over a defined treatment period, with monitoring to understand who may respond best and why. Enrollment requires specific liver stiffness measurements and excludes other serious liver diseases or recent drug-induced liver injury. The study helps researchers understand the drug's effects on the liver and potential differences in response among individuals.
Why it matters
Potential benefit: If successful, participants may experience improvements in liver fat, injury, and scarring, potentially slowing MASLD progression.
How similar studies have gone: Prior studies in similar liver disease targets have shown variable responses; this trial is evaluating ALN-CIDEB specifically in MASLD/MASH patients with rigorous safety and efficacy endpoints.
