Inclusion

  • Subjects are required to meet ALL of the following criteria for enrollment into the study:
  • Subject is a male or female between 18 to 75 years of age inclusive.
  • 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.
  • Subject shows presence of hepatic fat fraction as defined by ≥ 8% on MRI-PDFF and cT1 ≥ 800 ms at Screening.
  • Has had a stable body weight (±5%) within 6 months prior to Screening.
  • Body Mass Index (BMI) ≥ 28 kg/m2 at Screening
  • Has clinically normal resting 12-lead ECG at Screening Visit or, if abnormal, considered not clinically significant by the Principal Investigator.
  • Laboratory Screening results as indicated below:
  • AST:ALT Ratio ≤ 1, if AST or ALT value is \> ULN
  • Screening Liver enzymes (AST, ALT, and ALK PHOS) \< 5 x ULN.
  • Total Bilirubin ≤ 1.3 mg/dL (except if Gilbert's Disease)
  • Platelet count ≥ 150,000/mm3
  • International normalized ratio (INR) \< 1.3
  • Estimated Glomerular Filtration Rate (eGFR) ≥ 60/mL/min
  • Glycosylated hemoglobin (HbA1c) \< 9%.
  • Thyroid-Stimulating Hormone (TSH) within normal reference range. 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.
  • 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.
  • Subjects who are taking Vitamin E should be on a stable dose of Vitamin E (if ≥ 400 IU) for a period of at least 4 weeks prior to Screening and do not anticipate dose adjustments for the duration of the study.
  • Both male and female patients and their partners of childbearing potential must agree to use two medically accepted methods of contraception (e.g., barrier contraceptives \[male condom, female condom, or diaphragm with a spermicidal gel\], hormonal contraceptives \[implants, injectables, combination oral contraceptives, transdermal patches, or contraceptive rings\], or one of the following methods of birth control (intrauterine devices, tubal sterilization or vasectomy) or must practice complete abstinence from intercourse of reproductive potential from study entry to 6 months after the last day of treatment (excluding women who are not of childbearing potential and men who have been sterilized).
  • Females of child-bearing potential must have a negative serum pregnancy test at Screening Visit and negative urine pregnancy test prior to receiving the first dose of study drug; and Male participants must agree to use contraception and refrain from donating sperm for at least 90 days after the last dose of study intervention.
  • Subject is willing and able to give informed consent prior to any study specific procedures being performed.
  • Subject is willing and able to comply with scheduled visits, drug administration plan, laboratory tests, other study procedures and study restrictions

Exclusion

  • Subjects meeting ANY of the following criteria will be excluded from enrollment:
  • Any concurrent clinically significant liver disease with an etiology other than NASH including autoimmune hepatitis, alcoholic hepatitis, hypoxic/ischemic hepatopathy, and biliary tract disease.
  • History of alcohol consumption greater than 21/units/week (for males) and 14/units/week (for females) within the last 2 years prior to screening.
  • Note: Use of online unit calculator for alcohol consumption is recommended (e.g., https://alcoholchange.org.uk/alcohol-facts/interactive-tools/unit-calculator)
  • Any drug-induced steatohepatitis secondary to amiodarone, corticosteroids, estrogens, methotrexate, tetracycline, or other medications known to cause hepatic steatosis.
  • Undergone major surgery, including liver surgery, within 6 months prior to screening deemed clinically significant by the investigator.
  • Prior or pending liver transplantation.
  • History or presence of cirrhosis or stage 4 fibrosis in historical liver biopsy and/or hepatic decompensation including ascites, hepatic encephalopathy or variceal bleeding.
  • Active hepatitis B (defined as having a positive hepatitis B surface antigen \[HBsAg\] test), hepatitis C (defined as having a positive Anti-HCV test with detectable reflex HCV RNA; Note: Subject with positive Anti-HCV test and with undetectable HCV RNA would not be excluded), acute hepatitis A (defined as subjects with serum positive for hepatitis A IgM (HAV) antibody) or acute hepatitis E (defined as having anti-HEV IgM antibody).
  • Any active infection requiring systemic therapy at the time of screening, which is considered clinically significant per the Investigator.
  • Positive test for human immunodeficiency virus (HIV) or HIV infection.
  • History of bleeding diathesis within 6 months of screening.
  • Any malignancy within the past 5 years, excluding successfully treated basal cell carcinoma or squamous cell carcinoma without evidence of metastases.
  • Seizure disorder requiring ongoing antiseizure therapy or with any condition that, in the judgment of the investigator, is likely to increase the risk of seizure (e.g. CNS malignancy)
  • Clinically significant active cardiac disease which would interfere with study conduct or study results interpretation per the PI.
  • Any known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
  • Prior therapy with Leronlimab or any other CCR5 antagonist (e.g. maraviroc) within 6 months prior to screening.
  • History of severe allergic, anaphylactic, or other hypersensitivity reactions to humanized monoclonal antibodies.
  • Any condition requiring continuous systemic treatment with immunosuppressive (such as corticosteroids) or immunomodulatory medications.
  • Note: Inhaled or topical steroids of up to 5 mg daily prednisone equivalent dose are permitted in the bsence of active autoimmune disease.
  • History of administration of a live, attenuated vaccine within four weeks prior to start of PRO 140 treatment or anticipation that such a live attenuated vaccine will be required during the remainder of the study.
  • Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed. However intranasal influenza vaccines (e.g., Flu-Mist ®) are live attenuated vaccines, and are not allowed.
  • Currently participating in an investigational study or received an investigational drug within 28 days or 5 half-lives (whichever is longer) prior to study drug administration
