The Efficacy and Safety of Chiglitazar in Patients with MAFLD-related Cirrhosis

A total of 195 adult patients with biopsy-proven or clinically diagnosed metabolic dysfunction-associated with fatty liver disease(MAFLD)-related cirrhosis will be randomly divided into two arms. One arm will receive Chiglitazar(64 mg) treatment, while the other arm will receive placebo treatment, lasting for 72 weeks. Both the researchers and the participants will be blinded. The primary outcome is the reversal rate of cirrhosis assessed by magnetic resonance elastography. Secondary outcomes include outcome events, changes in histopathological fibrosis stage, non-invasive fibrosis tests, glucose and lipid metabolism indicators.


Eligibility Criteria:
Inclusion Criteria:

1. Men and women aged between 18 and 75 years (inclusive) who understand and sign informed consent forms; 2. Compensated MAFLD-related cirrhosis diagnosis(meet one of the following conditions):

1. The liver biopsy during the screening period (liver biopsy within 6 months of screening is acceptable) showing cirrhosis with steatohepatitis according to the Non Alcoholic Fatty Liver Disease Clinical Research Network (NASH-CRN) scoring system, and there is no evidence of competitive aetiology.
2. The liver biopsy during the screening period (liver biopsy within 6 months of screening is acceptable) showing cirrhosis with steatosis (no steatohepatitis) according to NASH-CRN scoring system, and there is no evidence of competitive aetiology. There are at least 2 coexisting metabolic comorbidities or history of metabolic comorbidities, including obesity and/or type 2 diabetes mellitus (T2DM).
3. Historical biopsy showed steatohepatitis, and now diagnosed with cirrhosis through non-invasive tests or clinical criteria (see criterion (5)-1)). There is no evidence of competing aetiology. There is at least 1 coexisting or history of metabolic comorbidity.
4. Historical biopsy showed steatosis (no steatohepatitis), and now diagnosed with cirrhosis through non-invasive tests or clinical criteria (see criterion (5)-1)). There is no evidence of competing aetiology. There are at least 2 coexisting metabolic comorbidities or history of metabolic comorbidities, including obesity and/or T2DM.
5. In the absence of biopsy, MAFLD-related cirrhosis is defined based on the following criterias:

   a. Cirrhosis is defined based on one of the following non-invasive tests(NITS): i: MRE ≥ 5kPa or VCTE-LSM ≥ 20kPa (when the patients with BMI ≥ 28kg/m2 , MRE ≥ 5kPa must also be met); ii:VCTE ≥15 kPa and \<20 kPa and 1 of the following: MRE≥4.45kPa or Agile4≥0.565 or Platelets≤150,000/µL; iii: VCTE \<15 kPa and 2 of the following: MRE≥4.45kPa or Agile4≥0.565 or Platelets≤150,000/µL; b. Current or previous imaging examinations have diagnosed fatty liver or controlled attenuation parameter (CAP)\>288dB/m or magnetic resonance imaging proton density fat fraction (MRI-PDFF)\>5%.

   c. There is no evidence of competing aetiology; d. There are at least 2 coexisting metabolic comorbidities or history of metabolic comorbidities, including obesity and/or T2DM.
6. If a participant's MAFLD-related cirrhosis diagnosis for eligibility is based on the biopsy screening period , no weight loss of ≥10% should have occurred in the same time period (based on medical history).
