Animal experiment: |
Rats[1]MSG obese rats (6 months old) are sorted into five treatment groups (n=10 each, male and female in half) based on decreased blood glucose in the insulin tolerance test, glucose levels, blood total triglyceride (TG), total cholesterol (TCHO), and initial body weight. From the next day, MSG obese rats receive single daily oral treatment with Chiglitazar (5, 10, and 20 mg kg-1 day-1, respectively), rosiglitazone (5 mg kg-1 day-1) or vehicle (water, 0.05% Tween 80) for 40 days. Normal wistar rats (n=10) serve as a normal group are treated with vehicle[1]. |

Chiglitazar is a PPARα/γ dual agonist, with EC50s of 1.2, 0.08, 1.7 μM for PPARα, PPARγ and PPARδ, respectively.
Comparative dose-response study of Chiglitazar is performed with rosiglitazone and pioglitazone for PPARγ, and WY14643 for PPARα. Chiglitazar shows significant activation of both the isoforms. Chiglitazar shows weaker PPARγ activating activity than rosiglitazone, but stronger than pioglitazone. In terms of PPARα activation, Chiglitazar shows more potent activity than rosiglitazone, pioglitazone, or WY14643 which is a selective PPARα agonist[1].
After insulin injection, plasma glucose levels in the MSG rats treated with Chiglitazar or rosiglitazone are significantly reduced compared with the control group treated with vehicle at all time points. Fasting PI levels are lower in animals treated with Chiglitazar and rosiglitazone than control. The ISIs of MSG obese rats treated with chiglitazar and rosiglitazone are significantly higher than control. Furthermore, Chiglitazar ameliorates the HOMA indices. For IPGTT, at the 30 min after glucose loading, the glucose values in the 5 and 10 mg /kg Chiglitazar and rosiglitazone-treatment groups are significantly lower than those in the vehicle treatment group. The integrated for the glucose response during the IPGTT in the treatment groups are significantly less than those in the control groups[1].

Chiglitazar: First Approval
Chiglitazar (Bilessglu?) is an orally administered, non-thiazolidinedione small-molecule agonist of 汐, 汛 and 污 peroxisome proliferator-activated receptors (PPARs) being developed by Chipscreen Biosciences for the treatment of type 2 diabetes (T2D) and non-alcoholic steatohepatitis. In October 2021, chiglitazar was approved in China for use as an adjunct to diet and exercise to improve glycaemic control in adult patients with T2D. The drug is also in phase 2 clinical development in China for the treatment of non-alcoholic steatohepatitis. This article summarizes the milestones in the development of chiglitazar leading to this first approval for the treatment of T2D.
Chiglitazar: a novel pan-PPAR agonist
Chiglitazar monotherapy with sitagliptin as an active comparator in patients with type 2 diabetes: a randomized, double-blind, phase 3 trial (CMAS)
Chiglitazar (Carfloglitazar) is a novel peroxisome proliferator-activated receptor (PPAR) pan-agonist that has shown promising effects on glycemic control and lipid regulation in patients with type 2 diabetes. In this randomized phase 3 trial, we compared the efficacy and safety of chiglitazar with sitagliptin in patients with type 2 diabetes who had insufficient glycemic control despite a strict diet and exercise regimen. Eligible patients were randomized (1:1:1) to receive chiglitazar 32 mg (n = 245), chiglitazar 48 mg (n = 246), or sitagliptin 100 mg (n = 248) once daily for 24 weeks. The primary endpoint was the change in glycosylated hemoglobin A1C (HbA1c) from baseline at week 24 with the non-inferiority of chiglitazar over sitagliptin. Both chiglitazar and sitagliptin significantly reduced HbA1c at week 24 with values of -1.40%, -1.47%, and -1.39% for chiglitazar 32 mg, chiglitazar 48 mg, and sitagliptin 100 mg, respectively. Chiglitazar 32 and 48 mg were both non-inferior to sitagliptin 100 mg, with mean differences of -0.04% (95% confidential interval (CI) -0.22 to 0.15) and -0.08% (95% CI -0.27 to 0.10), respectively. Compared with sitagliptin, greater reduction in fasting and 2-h postprandial plasma glucose and fasting insulin was observed with chiglitazar. Overall adverse event rates were similar between the groups. A small increase in mild edema in the chiglitazar 48 mg group and slight weight gain in both chiglitazar groups were reported. The overall results demonstrated that chiglitazar possesses good efficacy and safety profile in patients with type 2 diabetes inadequately controlled with lifestyle interventions, thereby providing adequate supporting evidence for using this PPAR pan-agonist as a treatment option for type 2 diabetes.
Comparative Evaluation of Chiglitazar and Sitagliptin on the Levels of Retinol-Binding Protein 4 and Its Correlation With Insulin Resistance in Patients With Type 2 Diabetes
Aims: We evaluated the efficacy and significant changes in the levels of retinol-binding protein 4 (RBP-4) and insulin resistance in patients with type 2 diabetes mellitus (T2DM) treated with chiglitazar versus sitagliptin.
Methods: Eighty-one T2DM patients with haemoglobin A1c (HbA1c) level of 7.5%-10.0% were selected. Based on the study criteria, patients were randomly assigned to receive chiglitazar (32 mg), chiglitazar (48 mg), or sitagliptin (100 mg) orally for 24 weeks. Sociodemographic and anthropometric characteristics, lipid profiles, glucose profiles, and serum RBP-4 levels were determined at baseline and at the end of the therapy.
Results: After treatment for 24 weeks, significant changes in fasting blood glucose (FBG), fasting insulin (Fins), 2 h-blood glucose (2h-BG), the score values of insulin resistance/insulin secretion/汕 cell function (HOMA-IR, HOMA-IS, and HOMA-汕), triglyceride (TG), free fatty acid (FFA), high-density lipoprotein cholesterol (HDL-C), and RBP-4 levels were detected in patients with chiglitazar administration and sitagliptin administration. Changes in RBP-4 levels were positively correlated with changes in HOMA-IR and 2 h-BG in linear regression.
Conclusions: Chiglitazar showed a greater improvement in parameters of diabetes than sitagliptin, and changes in serum RBP-4 levels were associated with changes in insulin-sensitizing parameters.

Effect of chiglitazar and sitagliptin on glucose variations, insulin resistance and inflammatory-related biomarkers in untreated patients with type 2 diabetes
Aims: To evaluate glycemic variations, changes in insulin resistance and oxidative stress after chiglitazar or sitagliptin treatment in untreated patients with type 2 diabetes mellitus (T2DM).
Methods: Based on the study inclusion and exclusion criteria, 81 patients with T2DM were randomly divided to receive chiglitazar or sitagliptin treatment for 24 weeks. Continuous glucose monitoring (CGM) systems were conducted for 72 h in eligible patients. We analyzed the following glycemic variation parameters derived from the CGM data and measured the serum levels of hemoglobin A1c (HbA1c), fasting blood glucose (FBG), 2-h postprandial blood glucose (2-h PBG), fasting insulin (Fins) and inflammatory-related indicators at baseline and the end of the study.
Results: After treatment for 24 weeks, our data showed a similar reduction in HbA1c between chiglitazar and sitagliptin. The 24-h mean blood glucose (MBG), standard deviation (SD) and mean amplitude of glycemic excursion (MAGE) were significantly decreased, and the time in range (TIR) was increased after chiglitazar and sitagliptin therapy. Chiglitazar administration led to significant improvement in insulin resistance/insulin secretion (HOMA-IR, HOMA-IS), interleukin-6 (IL-6), prostaglandin F2汐 (PGF-2汐), 17-hydroxyprogesterone (17-OHP) and adiponectin (ADP) score values compared with sitagliptin administration.
Conclusions: Chiglitazar therapy effectively reduced glucose variation and showed a larger improvement in insulin resistance and inflammatory parameters than sitagliptin.
