An Evaluation of the Safety and Efficacy of Nitazoxanide on Collagen Turnover in NASH Patients With Fibrosis

A Monocentric, Open-Label, Proof of Concept Study to Evaluate the Safety and Efficacy of Nitazoxanide at 500mg Twice Daily on Collagen Turnover in Plasma in NASH Patients With Fibrosis Stage 2 or 3

To evaluate the safety and tolerability of Nitazoxanide (NTZ) 500mg Twice Daily (BID) after 24 weeks of treatment in patients with NASH induced Stage 2 or Stage 3 fibrosis

Study Overview

• Status: Completed
• Conditions: Fatty Liver; Fibrosis, Liver; Compensated Cirrhosis; Non-alcoholic Steatohepatitis
• Intervention / Treatment: Drug: Nitazoxanide 500mg BID

Detailed Description

Based on the anti-fibrotic properties demonstrated in the animal models of fibrosis, this proof of concept clinical study aims at evaluating NTZ in patients with non-alcoholic steatohepatitis (NASH) and fibrosis stage 2 and 3. Although NTZ has been evaluated in liver disease populations up to 60 weeks, this is the first study evaluating NTZ treatment in a population with NASH induced stage 2 and 3 fibrosis. The aim of this study is to evaluate the safety and tolerability of NTZ 500 mg BID after 24 weeks of treatment in this population.

This proof of concept study will also evaluate the anti-fibrotic effect of NTZ as a secondary objective.

The methods of evaluation of fibrosis will include an innovative method of metabolic labeling.This approach is based on the concept that liver status can be determined by measuring the ratio of newly synthesized/pre-existing proteins.The turn-over rate of newly synthesized collagen and proteins represents the hepatic fibrogenic disease activity. Patients will be given "heavy water" to drink. Heavy water contains D20, deuterium being a stable isotope of hydrogen. Mass spectrometry is used to identify individual proteins and to quantify the ratio of labeled protein to total protein. The results are expressed as fractional synthesis rate of these proteins (FSR). This method has been previously published (Decaris et al, 2017).

Other non-invasive methods will be used to evaluate the liver stiffness changes after NTZ treatment: Magnetic Resonance Elastography (MRE) and FibroScan®.

Change in Controlled Attenuation Parameter (CAP) Score From Baseline to End of Treatment as Evaluated by FibroScan®	FibroScan is a specialized ultrasound machine that measures fibrosis (scarring) and steatosis (fatty change) in the liver. It was required that each subject's FibroScan® assessments be done with the same type of probe at each study visit. The CAP score is a measurement of fatty change in the liver, naming the steatosis grade. The CAP score is measured in decibels per meter (dB/m). It ranges from 100 to 400 dB/m. 100 to 237 dB/M indicates no hepatic steatosis, 238 to 260 dB/m indicates mild hepatic steatosis (steatosis S1), 260 to 290 dB/m indicates moderate steatosis (steatosis S2), and a CAP score greater than 290 dB/m indicates severe steatosis (steatosis S3).	24 weeks
