A Phase 2B, Randomized, Multi-Center, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Rencofilstat in Adult Subjects With Nonalcoholic Steatohepatitis and Advanced Liver Fibrosis
This is a randomized, double-blind, placebo-controlled, parallel-dosing, multi-center study to evaluate the efficacy and safety of Rencofilstat as evidenced by histopathological improvements in fibrosis in adult NASH subjects with F2 or F3 fibrosis (NASH CRN system). Antifibrotic biomarker activity will be evaluated on an exploratory basis.
• Male or female between 18 and 75 years of age (inclusive).
• Capable of giving written informed consent and able to effectively communicate with the investigator and study personnel.
• Histologic evidence of NASH based on central readings of the screening biopsy obtained no more than 6 months before Screening defined by presence of all 3 key histological features, Nonalcoholic Fatty Liver Disease Activity Score (NAS) ≥ 4 with at least 1 point each in lobular inflammation and hepatocyte ballooning.
• a. Historical biopsy may be substituted for Screening biopsy to determine eligibility if the following are met: i. Historical biopsy was obtained no more than 180 ± 5 days prior to the first day of Screening.
• ii. Hepatic tissue or slides are available for central histologic evaluation. iii. No new therapeutic intervention for NASH was made 90 days prior to screening (e.g., obeticholic acid, vitamin E ≥ 400 IU/day, pioglitazone, incretins \[e.g., liraglutide, semaglutide\], sodium-glucose cotransporter-2 \[SGLT2\] inhibitors).
• iv. Subjects must have been metabolically stable since the biopsy (no significant weight loss ≥ 7% of body weight, no major deterioration of glycemic control, and no introduction of new or investigational drugs for the treatment of Type 2 Diabetes).
• Histologic liver fibrosis stage 2 or 3 as defined by the Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) scoring of liver fibrosis based on central reading of the Screening biopsy (refer to criteria 4a regarding use of a historical biopsy as a substitute for the Screening biopsy).
• Blood pressure up to 160/100 mmHg; potential subjects who meet other eligibility requirements, but who have out of range blood pressure measurements deemed to be not clinically significant by the investigator, may still be considered for study inclusion.
