Primary Outcome Measures:
  • Primary objective is to characterize safety for GR-MD-02 administered intravenously to subjects w/ biopsy-proven NASH w/ advanced liver fibrosis. Specifically assessed by number of subjects experiencing TEAEs. [ Time Frame: Baseline; Week 1-7 (End of Study); Week 9; Week 11 (Follow-up) ] [ Designated as safety issue: No ]
    The primary objective of this study is to characterize the safety, which includes the tolerability and dose-limiting toxicity (DLT), for GR-MD-02 when administered intravenously to subjects with biopsy-proven NASH with advanced liver fibrosis. Specifically, this measure will be assessed by number of subjects experiencing treatment emergent adverse events indicative of DLT.


Secondary Outcome Measures:
  • A secondary objective is to characterize the first-dose PK profile of GR-MD-02. The PK profile is assessed by the AUC (area under the plasma concentration versus time curve) and Cmax (peak plasma concentration) of GR-MD-02. [ Time Frame: Baseline; Week 1-4 ] [ Designated as safety issue: No ]
    A secondary objective for the study is to characterize the first-dose PK profile of GR-MD-02 administered as an IV infusion. Specifically, the PK profile is assessed by the AUC (area under the plasma concentration versus time curve) and Cmax (peak plasma concentration) of GR-MD-02.

  • A secondary objective for the study is to characterize the PK profile and serum level accumulation of GR-MD-02 following administration of 3 subsequent weekly doses given by IV infusion beginning 28 days after the first dose. [ Time Frame: Baseline; Week 5-7 (End of Study) ] [ Designated as safety issue: No ]
    A secondary objective for the study is to characterize the PK profile and serum level accumulation of GR-MD-02 following administration of 3 subsequent weekly doses given by IV infusion beginning 28 days after the first dose.

  • A secondary objective is to evaluate change in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), ratio of AST:ALT, alkaline phosphatase, and gamma glutamyl transpeptidase (GGTP); change in AST/platelet ratio index. [ Time Frame: Baseline; Week 7 (End of Study) ] [ Designated as safety issue: No ]
    A secondary objective for this study is to evaluate change in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), ratio of AST:ALT, alkaline phosphatase, and gamma glutamyl transpeptidase (GGTP) levels; and change in AST/platelet ratio index.

  • A secondary objective for this study is to evaluate changes in exploratory pharmacodynamic biomarkers in serum [ Time Frame: Baseline; Week 7 (End of Study) ] [ Designated as safety issue: No ]
    A secondary objective for this study is to evaluate levels of exploratory pharmacodynamic biomarkers in serum including galectin-3, inflammatory, cell-death, and fibrosis markers.

Detailed Description:

This study is a dose ranging study to assess in sequential fashion, the safety, tolerability, and dose limiting toxicities (DLTs) of GR-MD-02, in subjects with biopsy-proven NASH with advanced fibrosis. This is a dose escalation design comprised of 3 sequential cohorts to evaluate the safety of GR MD 02 when administered as a single IV infusion followed by 3 additional weekly infusions starting 28 days after the first dose. Each cohort will consist of 8 subjects, 6 randomized to receive active drug and 2 randomized to receive placebo.Based on data safety monitoring board (DSMB) and FDA review, 2 additional cohorts may be implemented, consisting of 8 subjects.

  Eligibility

Ages Eligible for Study:   18 Years to 74 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Subjects meeting all of the following criteria will be considered for admission to the study:

  1. Institutional Review Board (IRB approved written Informed Consent and privacy language as per national regulation (eg, Health Insurance Portability and Accountability Act [HIPAA] Authorization for US sites) must be obtained from the subject or legally authorized representative prior to any study related procedures, including screening evaluations and tests.
  2. Subject is ≥ 18 years of age and < 75 years old at the time of consent.
  3. Subject has had a percutaneous liver biopsy within 12 months from Screening that shows a definitive diagnosis of NASH with advanced (Brunt stage 3) hepatic fibrosis.

Sexually active males and females of childbearing potential must agree to use adequate contraception (condoms, intra-uterine contraceptive device, implants, injectables, sexual abstinence or vasectomized partner) throughout their participation in this study and for 30 days after the last dose of study drug. Women of childbearing potential must have a negative urine pregnancy test within 7 days prior to the first dose.
