This phase 2a study is a multi-center, double-blind randomized, placebo-controlled study. The study is designed to determine the safety and tolerability of the anti-human CCL24 monoclonal antibody CM-101 in adult patients with non-cirrhotic nonalcoholic steatohepatitis (NASH) patients with stage 1c, 2 or 3 fibrosis. The patients will be randomized to 1 of 2 treatment groups: 5 mg/kg CM-101 or placebo.

This study will consist of screening period, treatment period and follow-up period. Adults with NASH will be included. Each subject will undergo screening procedures within up to 42 days prior to Randomization, to assess eligibility to participate in the study. After randomization patients will receive a dose of investigational product once every 2 weeks for a total of 8 administrations. This will result in a total coverage of 16 weeks. Study participation will last for up to approximately 26 weeks (up to 6 weeks for screening followed by 14 weeks treatment and 6 weeks follow-up).

Inclusion Criteria:

• Histological confirmation of steatohepatitis and fibrosis without cirrhosis on a diagnostic liver biopsy obtained within the 18 months prior to the start of treatment, and/or during the screening period with:

  a. NAS ≥ 4 with a score of at least 1 for each component (steatosis, ballooning degeneration and lobular inflammation) and b. Hepatic fibrosis stage F1c, 2 or 3 as defined by the NASH CRN scoring scale. F1c subjectspatients must have either: PRO-C3 >14 ng/ml or Liver stiffness value of >8.0 kPa measured by transient elastography

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 documented postmenopausal or surgically sterilized women;

• Male patients must agree to use a barrier method of contraception (condom with spermicidal jelly, foam suppository, or film; diaphragm with spermicide; or male condom and diaphragm with spermicide) or abstinence for the duration of study participation through 60 days after the last dose of the study medication.

• Patients able to understand and sign a written informed consent form (ICF), communicate with the investigator, and understand and comply with protocol requirements.

Exclusion Criteria:

• Patients with medical/surgical history of bariatric surgery procedures or bariatric device insertion or patients that are planned for such interventions;

• Evidence of drug induced steatohepatitis secondary to amiodarone, corticosteroids, estrogens, methotrexate, tetracycline, or other medications known to cause hepatic steatosis;

• History or presence of cirrhosis (compensated or decompensated) determined by histology or relevant medical complications and laboratory parameters;

• Model for End-stage Liver Disease (MELD) score >12;
