Positive results from Phase II clinical trial (CGZ203 study) of Chiglitazar monotherapy for non-alcoholic steatohepatitis

SHENZHEN, China, March 18, 2024 /PRNewswire/ -- On March 18 2024, Shenzhen chipscreen biosciences Co., Ltd. (hereinafter referred to as "chipscreen biosciences", stock code: 688321. SH) announced that the Phase II clinical trial (CGZ203 study) of chiglitazar monotherapy for non-alcoholic steatohepatitis (NASH) was successfully completed with data cleaning and database locking on February 22, 2024. The primary efficacy endpoint of the trial has been achieved, and further data analysis is currently underway.

The incidence of non-alcoholic fatty liver disease (NAFLD) or metabolic associated fatty liver disease (MAFLD) in the general population of China exceeds 25%, of which about 25% will progress to NASH, and this proportion is even higher in patients with metabolic syndrome. Currently, there is only one thyroid receptor β (TRβ) agonist approved worldwide.

The CGZ203 study is a randomized, double-blind, placebo-controlled, multicenter Phase II clinical trial aimed to evaluate the safety and preliminary efficacy of chiglitazar monotherapy in diagnosed NASH patients. The CGZ203 study was led by Beijing Friendship Hospital affiliated to Capital Medical University and conducted in 24 clinical sites nationwide.

Preliminary results showed that both dose groups of chiglitazar produced significant and dose-dependent reductions at the primary efficacy endpoint (the proportion of changes from baseline in liver fat content evaluated by MRI-PDFF after 18 weeks of treatment), compared to placebo control group. In terms of secondary efficacy endpoints such as the proportion of patients with an over 30% decrease in liver fat content, non-invasive indicators related to hepatocyte damage, inflammation, and fibrosis and so on, both dose groups of chiglitazar also showed significant or dose-dependent trend of improvements. The overall safety is good.

The detailed research results will be presented on an upcoming scientific conference or in research article.

About Chiglitazar:

Chiglitazar (Carfloglitazar) is a novel peroxisome proliferator activation related receptor (PPAR) pan-agonist, independently discovered and developed by Shenzhen chipscreen biosciences with global patent protection. It was firstly approved in China in October 2021, for clinical treatment of type 2 diabetes patients who cannot be effectively controlled by exercise and diet control. It is also the first approved PPAR pan-agonist in the world.

Chiglitazar has already completed a phase III trial of combination with metformin to treat type 2 diabetes patients (RECAM study) and the current phase II trial in NASH patients (CGZ203) in China.

About CGZ203:

CGZ203 is an exploratory phase II trial aimed at treating NASH patients. It was designed as a randomized, double-blind, placebo-controlled multicenter clinical trial. The clinically diagnosed NASH patients were randomly enrolled in a ratio of 2:2:1 to receive oral administration of chiglitazar 48 mg, 64 mg, and placebo once a day respectively, with a treatment period of 18 weeks. The primary efficacy endpoint is the percentage of changes from baseline in liver fat content (LFC) evaluated by magnetic resonance proton density fat fraction (MRI-PDFF) after 18 weeks of treatment. Secondary endpoints include the absolute value of LFC changes, the proportion of people with a decrease of more than 30% in LFC, changes in other non-invasive indicators of liver cell damage, inflammation, and fibrosis, and the patient safety during the trial period.
