Brief Summary

The primary objective of this study is to characterize the safety, tolerability and dose-limiting toxicities (DLTs) for GR-MD-02 when administered intravenously to subjects with biopsy-proven NASH with advanced liver fibrosis.

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 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.

4. 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. Post-menopausal women must have been amenorrheic for at least 12 months to be considered of non-child-bearing potential.

Exclusion Criteria

Subjects meeting any of the following criteria will be excluded from the study:

1. Subject is a pregnant or lactating female.

2. Subject with current, significant alcohol consumption or a history of significant alcohol consumption for a period of more than 3 consecutive months any time within 1 year prior to screening. Significant alcohol consumption is defined as more than 20 gram per day in females and more than 30 grams per day in males, on average (a standard drink in the US is considered to be 14 grams of alcohol).

3. Subject is unable to reliably quantify alcohol consumption based upon local study physician judgment.

4. Subject uses drugs historically associated with nonalcoholic fatty liver disease (NAFLD) (amiodarone, methotrexate, systemic glucocorticoids, tetracyclines, tamoxifen, estrogens at doses greater than those used for hormone replacement, anabolic steroids, valproic acid, and other known hepatotoxins) for more than 2 weeks in the year prior to Screening.

5. Subject requires use of drugs with a narrow therapeutic window metabolized by CYP3A4 such as fast acting opioids (alfentanil and fentanyl), immunosuppressive drugs (cyclosporine, sirolimus, and tacrolimus), some cardiovascular agents (ergotamine, quinidine and dihydroergotamine), and select psychotropic agents (pimozide).

6. Subject has prior or has planned (during the study period) bariatric surgery (eg, gastroplasty, Roux-en-Y gastric bypass).

7. Subject has concurrent infection including diagnoses of fever of unknown origin and evidence of possible central line sepsis (subjects must be afebrile at the start of therapy).

8. Subject with a platelet count below 100,000/mm3 at Screening.

9. Subject with clinical evidence of hepatic decompensation as defined by the presence of any of the following abnormalities at Screening:
