Brief summary

This is a phase II study of of Leronlimab (PRO 140)-Humanized monoclonal antibody to CCR5 in patients with Nonalcoholic Steatohepatitis (NASH).

Detailed description

This is an exploratory phase II, multi-center, two-part study (Part 1: randomized, placebo-controlled, two-arm with 60 patients; Part 2: non-randomized, single-arm, open-label with 30 patients) designed to evaluate the safety and efficacy of leronlimab after subcutaneous (SC) administration in patients with NASH for 13 weeks. A Follow Up visit was conducted 28 (± 3) days after receiving the last study treatment (i.e., after last dose of Leronlimab (PRO 140) or placebo.

Evidence of nonalcoholic steatohepatitis (NASH) based on one of the following criteria: * Criteria 1: Histologically-confirmed diagnosis of NASH on a liver biopsy, or * Criteria 2: FibroScan or Shearwave US during screening (or within 6 months before screening) shows kPa ≥7 but \<14 and CAP ≥260. 3. Subject shows presence of hepatic fat fraction as defined by ≥ 8% on MRI-PDFF and cT1 ≥ 800 ms at Screening. 4. Has had a stable body weight (±5%) within 6 months prior to Screening. 5. Body Mass Index (BMI) ≥ 28 kg/m2 at Screening 6. Has clinically normal resting 12-lead ECG at Screening Visit or, if abnormal, considered not clinically significant by the Principal Investigator. 7. Laboratory Screening results as indicated below: 1. AST:ALT Ratio ≤ 1, if AST or ALT value is \> ULN 2. Screening Liver enzymes (AST, ALT, and ALK PHOS) \< 5 x ULN. 3.

Note: Any subject with a non-clinically significant TSH value outside of the normal range may be enrolled if their T3 and free T4 values are within the normal range. 8. Subjects with pre-diabetes or type 2 diabetes will be allowed to participate if the following criteria is met: * Subjects who are taking anti-diabetic medications should be on a stable dose for a period of at least 3 months prior to Screening and do not anticipate clinically significant dose adjustments during the course of study. * Subjects must be on a stable diet/lifestyle regimen for at least 3 months prior to screening and do not anticipate a clinically significant change during the course of study. 9.
