About
The goal of this randomized, double-blind, placebo controlled, Multicenter Phase II clinical trial is to initially evaluate the Safety and Efficacy of MT2004 Capsule in Cholestatic and Mixed drug induced liver injury (DILI) subjects.
The main questions it aims to answer are:
Full description
Xi'An Aolitai Pharmaceutical Technology Co Ltd is developing MT2004, a novel investigational synthetic small molecule farnesoid X receptor (FXR) agonist targeted to the liver. The MT2004 was designed as the prodrug and the metabolites MT2004-met1 of MT2004 will act to the FXR receptor to regulate a series of genes expression. It also plays an important role in the metabolism of bile acids, lipids and sugars.
The goal of this randomized, double-blind, placebo controlled, Multicenter Phase II clinical trial is to initially evaluate the Safety and Efficacy of MT2004 Capsule in Cholestatic and Mixed drug induced liver injury (DILI) subjects. The whole study will be divied to three stages including screening period (14 Days before the treatment), treatment period (the participants will be randomized to receive MT2004, or placebo orally (BID), for 12 weeks) and follow-up period. The study aims to recruit total of 80 subjects with Cholestatic and Mixed DILI, in which 12 of subjects will be firstly enrolled and allocated to the MT2004 group (Dose level: 25mg) as well as control group with the proportion of 2:1 by using the stratified randomization method. During the whole study, the adjustment of the subjects amount, the dose level as well as randomization proportion will based on the decesion of Independent Data Monitoring Board (IDMC). The highest dose will not exceed the 50mg BID.
The placebo will be used in this study, and the researchers will compare the placebo and test article to see the safety and efficacy.

Inclusion criteria
18≤ age ≤ 75 years, male or female.
When diagnosis of acute DILI, the liver biochemical threshold of patients must meet one of the following criteria: ：(1) ALT ≥5 ×ULN；(2) ALP ≥2× ULN；(3) ALT≥3× ULN and TBil ≥2×ULN.
ALP ≥2× ULN, and conform to the clinical classification of cholestatic type or mixed type DILI in the Chinese Guidelines for the Diagnosis and Treatment of Drug-induced Liver Injury (2023 edition) (cholestatic type: R value ≤2; Mixed type: 2<R value <5).
Excluded other common causes of acute liver injury, such as acute viral hepatitis A, B, C, E, autoimmune hepatitis, biliary tract disease, PBC, etc. (Exclusive diagnostic tests completed in our hospital or other hospitals after this suspected acute DILI event or within 2 months before screening were acceptable)
RUCAM causality scale score ≥6 points; If the RUCAM score is between the 3-5 it is necessary to evaluate the causal relationship by three experts according to the evaluation criteria of expert opinions in the Chinese Guidelines for the Diagnosis and Treatment of Drug-induced Liver Injury (2023 edition), and at least two experts determine that the liver injury of the patients are "likely", "very likely" or "definitely" caused by drugs.
The serious level of DILI is within level 1-2 based on the Chinese Guidelines for the Diagnosis and Treatment of Drug-induced Liver Injury (2023 edition).
The duration of this liver injury is less than 6 months.
The female with fertility must have had a negative pregnancy test results before being enrolled, or at least 1 year after pausimenia, or permanent sterilization ≥6 weeks（There should have a recording of hysterectomy, bilateral salpingo-oophorectomy）. The female and their male partners with the fertility potential agree to utilize the effective contraceptive methods（the following two methods can be selected: 1. any of the condom, diaphragm, Sponge or Cervical Cap with with Spermicide ）.
Fully understand the study process of the clinical trial, and provide the signed ICF of joinning the clinical trial.
