Brief summary

The purpose of this study is to assess the effect of multiple ION224 doses when administered by subcutaneous (SC) injection for 49 weeks (end of the treatment \[EOT\]) on non-alcoholic steatohepatitis (NASH) histologic improvement and to assess the effect on liver steatosis by magnetic resonance imaging-determined proton density fat fraction (MRI-PDFF), additional changes in NASH histologic features, liver biochemistry tests, and plasma lipid profile.

Detailed description

This is a Phase 2, double-blind, randomized, placebo-controlled study of ION224 in up to 150 participants. The study consists of 3 periods: 1) Screening Period: Week -8 to Week -1 (up to 8 weeks); 2) Treatment Period up to Week 49; and 3) Post-Treatment Period: Week 50 to Week 62 (12 weeks). Initially, 48 patients will be enrolled in three different dose cohorts to receive ION224 or placebo every four weeks and based on safety and effects on liver steatosis (assessed at Week 15), two dose cohorts will be selected to be expanded. After dose selection, an additional 102 patients will be enrolled in the 2 selected dose cohorts and will receive ION224 or placebo for up to 49 weeks. Participants in the 3rd cohort (not selected) will continue to complete up to 49 weeks of treatment without any cohort expansion.

Primary

MeasureTime frameDescription
Percentage of Participants With at Least 2-point Reduction in Non-alcoholic Fatty Liver Disease Activity Score (NAS) With at least 1-point Improvement in Hepatocellular Ballooning or Lobular Inflammation, and Without Worsening in Fibrosis Stage at EOTUp to Week 49The NAS is a histology grading score composed on the assessment of steatosis (scale 0-3), hepatocellular ballooning (scale 0-2), and lobular inflammation (scale 0-3), with higher scores indicating more severe hepatitis. Worsening of fibrosis is defined as an increase in fibrosis of at least one stage on the Kleiner fibrosis classification: fibrosis stages range from 0-4, with higher scores indicating greater fibrosis (0=None, 4=Cirrhosis).
