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.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Steatohepatitis, Nonalcoholic | Drug: ION224 Other: Placebo | Phase 2 |
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 Outcome Measures :
- 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 EOT [ Time Frame: Up to Week 49 ]The 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).
Secondary Outcome Measures :
- Change From Baseline in Hepatic Fat Content Measurement as Evaluated by MRI-PDFF and Calculated by an Independent, Blinded-To-Treatment, Central Reader [ Time Frame: Baseline up to Week 15, Week 29 and Week 49 ]
- Percentage of Participants Achieving Non-alcoholic Steatohepatitis (NASH) Resolution, as Defined by Scores of 0 for Ballooning and 0 or 1 for Inflammation by the NAS, and Without Worsening of Fibrosis, Assessed Through Liver Biopsy at the EOT [ Time Frame: Up to Week 49 ]
- Percentage of Participants Achieving Reduction of at Least 1 Stage in the Fibrosis Score, and Without Worsening of Steatohepatitis by the NAS, Assessed Through Liver Biopsy at the EOT [ Time Frame: Up to Week 49 ]
- Percentage of Participants Achieving a Combination of NASH Resolution and a 1 Stage Improvement in Fibrosis at the EOT [ Time Frame: Up to Week 49 ]
- Percentage of Participants With Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) Less than or Equal to (≤) 1.5 Upper Limit of Normal (ULN) at the EOT [ Time Frame: Up to Week 49 ]
- Absolute Change From Baseline in Liver-related Laboratory Test - ALT [ Time Frame: Baseline up to Week 49 ]
- Absolute Change From Baseline in Liver-related Laboratory Test - AST [ Time Frame: Baseline up to Week 49 ]
- Absolute Change From Baseline in Liver-related Laboratory Test - Total Bilirubin [ Time Frame: Baseline up to Week 49 ]
- Absolute Change From Baseline in Liver-related Laboratory Test - Gamma-glutamyl Transferase [ Time Frame: Baseline up to Week 49 ]
- Absolute Change From Baseline in Plasma Fasting Lipid Profile Test - Triglyceride (TG) [ Time Frame: Baseline up to Week 49 ]
- Absolute Change From Baseline in Plasma Fasting Lipid Profile Test - Total Cholesterol [ Time Frame: Baseline up to Week 49 ]
- Absolute Change From Baseline in Plasma Fasting Lipid Profile Test - Low-density Lipoprotein-cholesterol (LDL-c) [ Time Frame: Baseline up to Week 49 ]
- Absolute Change From Baseline in Plasma Fasting Lipid Profile Test - High-density Lipoprotein-cholesterol (HDL-c) [ Time Frame: Baseline up to Week 49 ]
- Maximum Observed Plasma Concentration (Cmax) of ION224 and Metabolites [ Time Frame: Baseline up to Week 49 ]
- Time to Cmax (Tmax) of ION224 and Metabolites [ Time Frame: Baseline up to Week 49 ]
- Area Under the Plasma Concentration-time Curve (AUC) of ION224 and Metabolites [ Time Frame: Baseline up to Week 49 ]
- Plasma Half-life (t½) of ION224 and Metabolites [ Time Frame: Baseline up to Week 49 ]
