Brief summary

This is a Phase 2a study to evaluate the safety, tolerability, efficacy, pharmacokinetics, and pharmacodynamics of oral (PO) daily (QD) doses of ALG-055009 (soft gelatin \[softgel\] capsule) for 12 weeks.

Detailed description

This is a double-blind, randomized, placebo-controlled Phase 2a study to evaluate the safety, tolerability, efficacy, pharmacokinetics, and pharmacodynamics of oral (PO) daily (QD) doses of ALG-055009 (soft gelatin \[softgel\] capsule) for 12 weeks. The study will be conducted in approximately 100 adult non-cirrhotic subjects with presumed MASH and liver fibrosis (F1-F3). The study will be conducted at up to approximately 45 sites throughout the United States of America.

Inclusion criteria

Key Inclusion Criteria: * Male or female, 18 to 75 years of age * Body mass index (BMI) ≥ 25 kg/m2 * Diagnosis of presumed NASH/MASH with F1-F3 liver fibrosis based on one of the following: * Liver biopsy within 6 months prior to screening showing a NAFLD activity score (NAS) of ≥4 with at least a score of 1 in each of the NAS components; OR * Having ≥2 metabolic syndrome criteria and a screening FibroScan liver stiffness measurement between 7 - 20 kPa * Screening FibroScan with CAP score of \>300 dB/m * Screening MRI-PDFF with ≥10% liver fat content Key
