Emricasan, a Caspase Inhibitor, for Treatment of Subjects With Decompensated NASH Cirrhosis

The study treatment duration will be at least 48 weeks with study visits every 4 weeks up to
Week 48 and every 8 weeks after Week 48. All subjects will continue treatment until the last
subject in the study reaches 48 weeks in the study. At least 30% of subjects randomized
should have baseline MELD score ≥15 and ≤20.

For each subject, the study will consist of:

- Screening period of up to 4 weeks

- Randomized, double-blind treatment period of at least 48 weeks

- A follow-up visit 2 weeks after completion of study drug treatment

The duration of each subject's participation will be at least 54 weeks for those completing
the entire study.

Key Inclusion Criteria:

1. Male or female subjects 18 years or older, able to provide written informed consent
and able to understand and willing to comply with the requirements of the study.

3. At least one of the following: a) history of variceal hemorrhage (more than 3 months

at least moderate ascites (on physical exam or imaging) currently treated with
diuretics.

4. MELD score ≥12 and ≤20 during screening

5. Albumin ≥2.5 g/dL during screening

6. Serum creatinine ≤1.5 mg/dL during screening

Key Exclusion Criteria:

1. Evidence of severe decompensation

2. Non-cirrhotic portal hypertension

20. Human immunodeficiency virus infection

21. Use of alcohol, controlled substances (including inhaled or injected drugs), or
