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.

Eligibility criteria: Inclusion Criteria:

1. Patients with US confirmation of NAFLD without evidence of NASH;
2. Patients with normal liver function tests (i.e. ALT, AST and ALP).
3. Patients in general good health expected for the preceding 6 months;
4. Women of childbearing potential must agree to use an approved form of contraception prior to study entry and for the duration of study participation through 60 days after the last dose of the study medication. Confirmation that female patients are not pregnant must be established by a negative serum β-human chorionic gonadotropin (β-hCG) pregnancy test result obtained during screening. Pregnancy testing is not required for postmenopausal or surgically sterilized women;
5. Male patients must agree to use a barrier method of contraception or abstinence for the duration of study participation through 60 days after the last dose of the study medication;
6. Patient must be able to read, understand, and sign the informed consent forms (ICF), communicate with the investigator, and understand and comply with protocol requirements

Exclusion Criteria:
