一项评估代谢功能障碍相关的脂肪分裂肝病或代谢功能障碍相关的脂肪性肝炎（MASLD/MASH）的成年参与者的ALN-CideB的研究

2026年11月1日 更新者：Regeneron Pharmaceuticals

A Phase 1/2a, Randomized, Double-Blind, Placebo-Controlled, Two-Part Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of a Single Dose of ALN-CIDEB in Adult Participants With Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) and Two Doses of ALN-CIDEB in Adult Participants With Metabolic Dysfunction-Associated Steatohepatitis (MASH)

This study is researching an experimental drug called ALN-CIDEB, also referred to as "study drug". The study is focused on participants with metabolic dysfunction-associated steatotic liver disease (MASLD) (Part A) and metabolic dysfunction-associated steatohepatitis (MASH) (Part B). MASLD and MASH are long-lasting liver conditions caused by having too much fat in the liver.

The aim of the study is to see how safe and tolerable the study drug is.

The study is looking at several other research questions, including:

  • What side effects may happen from taking the study drug
  • How the study drug works to change liver fat content
  • How much study drug and study drug metabolites (byproducts of the body breaking down the study drug) are in the blood at different times

  6. Part B: A diagnosis of MASH documented in the participant's medical history, or a clinical suspicion of MASH based on non-invasive biomarkers (eg, evidence of fatty liver on imaging and elevated liver enzymes) and clinical risk factors, including having a history of 2 or more elements of metabolic syndrome, as defined in the protocol

Key Exclusion Criteria:

  1. Known historical or current diagnosis of portal hypertension or cirrhosis based on clinical assessment, imaging, and/or liver biopsy
  2. Known historical or current diagnosis of other forms of chronic liver disease, as defined in the protocol
  3. Prior or current suspected or known drug-induced liver injury within 1 year prior to screening
  4. History of liver transplant, current placement on a liver transplant list, or Model for End-stage Liver Disease (MELD) score >12
  5. Contraindication to MRI examinations, such as persons with cardiac pacemaker and implants made of metal, severe claustrophobia, size restrictions, or other contraindications for MRI
  6. Liver stiffness measurement, laboratory parameter assessment, estimated Glomerular Filtration Rate (GFR), and evidence of uncontrolled hypertension, as defined in the protocol
  7. Evidence of Human Immunodeficiency Virus (HIV) infection, Hepatitis B Virus (HBV) infection, or Hepatitis C Virus (HCV) infection during screening, as described in the protocol
  8. History of Type 1 Diabetes
  9. Bariatric surgery, including any procedures to revise, reverse, or remove any previous bariatric surgery interventions, within approximately 5 years prior to randomization or planned during the study period

NOTE: Other protocol-defined inclusion/exclusion criteria apply.
