简要总结
This study is a Phase 1, first-in-human single-dose escalation and multiple dose study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of OA-235i in subjects with nonalcoholic steatohepatitis.
详细描述
The purpose of this study is to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of a single ascending dose (SAD) in participants with suspected or confirmed diagnosis of noncirrhotic nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH) without advanced hepatic fibrosis. This dose-escalating strategy will test the safety of OA-235i when given as a single subcutaneous dosage using up to five successive cohorts. Each cohort will have three non-randomized participants receiving the active medication. One (1) planned multiple dose (MD) randomized, placebo-controlled expansion cohort with 9 NAFLD/NASH subjects will be enrolled for a 7-day dosing regimen at a dose level to be determined from the SAD portion of the study.

入选标准
- •Male and female subjects between the ages of 18 and 70 years, inclusive, at Screening.
- •Suspected or confirmed diagnosis of noncirrhotic NAFLD/NASH without advanced hepatic fibrosis by one of the following:
- •Histologically with liver biopsy within 2 years prior to Screening (documentation with pathology report); or
- •Radiologically with ≥5% steatosis measured by magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF), or controlled attenuation parameter (CAP) >238 dB/m via FibroScan assessment, or presence of hepatic steatosis on abdominal ultrasound ; or
- •Clinically with a diagnosis of Metabolic Syndrome (MetS) reflecting the presence of at least 3 of 5 factors/criteria (ie, abdominal obesity, elevated triglycerides, reduced HDL-C, elevated blood pressure, and/or elevated fasting glucose [IFG or type 2 diabetes mellitus]) as defined by the National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) [Grundy 2005]; and fatty liver on imaging within 1 year prior to Screening.
排除标准
- •History or presence of cirrhosis as assessed by Investigator following review of diagnostic measures (clinical, imaging, histopathology, or laboratory).
- •Clinical evidence of hepatic decompensation (laboratory or clinical abnormalities- ascites, variceal bleeding, etc.).
- •History or presence of other concomitant liver disease (eg, hepatitis B & C, alcoholic liver disease, autoimmune liver disease, primary biliary cirrhosis, primary sclerosing cholangitis, hemochromatosis, Wilson's disease, alpha-1 antitrypsin (A1AT) deficiency, bile duct obstruction, liver primary or metastatic cancer, drug-induced liver disease.
