The Study of Multiple Doses of CM-101 in Male and Female NAFLD (Nonalcoholic Fatty Liver Disease) and NAFLD/NASH (Nonalcoholic Steatohepatitis) Subjects

Study Overview
=================
Brief Summary
-----------------
A two-part study for NAFLD subjects with normal liver functions and in general good health to be treated with CM-101 or matching placebo and NAFLD/NASH Activity Score (NAS) < 3 that are in general good health and have normal liver functions to be treated with CM-101.

Detailed Description
-----------------
This study is designed to assess the safety and preliminary pharmacodynamics of repeated administrations of CM-101 in two subject populations. The objective of part one of this study is to demonstrate that repeated treatment with CM-101 will be safe and well tolerated in NAFLD subjects that have normal liver functions and are in general good health. A second expansion part will be carried out that will include patients with NAFLD/NASH Activity Score (NAS) < 3 that are in general good health and have normal liver functions.

Any laboratory abnormality or condition that, in the investigator's opinion, could adversely affect the safety of the patient or impair the assessment of study results. Presence of any condition that could, in the opinion of the investigator, compromise the patient's ability to participate in the study, including a history of substance abuse or a psychiatric condition requiring hospitalization or emergency room visit within 2 years of Screening; Patients with the following blood test abnormalities: Abnormal coagulation tests: INR, Total bilirubin (TB) ≥2 ULN, Serum Albumin < 3.4 g/dL, Platelet count <130 × 10^9/L; History of or current significant alcohol consumption for a period of more than 3 consecutive months within 1 year prior to screening (significant alcohol consumption is defined as more than 20 g/day in females and more than 30 g/day in males, on average); Patients with history of substance abuse (including alcohol abuse as defined above) in the past or a positive screen for drugs of abuse (opioids and cannabinoids) or alcohol at screening; Female patients who are pregnant or nursing, or male/female patients who are planning a pregnancy during the course of the study; Patients that are unavailable for follow-up assessments or any concern the investigator may have for patient's compliance with the protocol procedures; Patients that are currently participating or have participated in an interventional clinical study within 3 months prior to screening
