Chiglitazar Added to SGLT-2 Inhibitors for Type 2 Diabetes

May 5, 2026 updated by: Chipscreen Biosciences, Ltd.

Chiglitazar Add-On to SGLT-2 Inhibitors in Patients With Type 2 Diabetes: A Nationwide, Multicenter Registry Study (C-STAR)

The goal of this observational study is to evaluate the comprehensive clinical efficacy, cardiovascular, renal, and hepatic benefits, as well as the safety of adding Chiglitazar to SGLT-2 inhibitor therapy in adult patients with Type 2 Diabetes Mellitus (T2DM) . The main questions it aims to answer are:

What is the real-world effectiveness of Chiglitazar, when added to an SGLT-2 inhibitor, on glycemic control? What are the effects of this combination therapy on cardiovascular, renal, and hepatic outcomes? What is the overall safety of this treatment regimen?

This is a non-interventional study. Participants will be prescribed Chiglitazar or other oral antidiabetic drugs by their treating physician as part of their routine clinical care. For the purpose of this registry study, data will be collected from their regular medical follow-ups. Participants will:

Attend regular follow-up visits as part of their standard diabetes care. Have data collected from their routine clinical assessments.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Chiglitazar Cohort (Exposure Group)
Participants with T2DM on a background SGLT-2 inhibitor-based therapy who are newly prescribed Chiglitazar by their treating physician. This cohort includes patients on dual therapy (SGLT-2i + Chiglitazar) or triple therapy (SGLT-2i + Chiglitazar + another oral antidiabetic drug).
Drug: SGLT-2 inhibitor and Chiglitazar
Prescribed as an add-on therapy to an SGLT-2 inhibitor-based regimen according to the physician's clinical judgment and routine practice
Comparator Cohort (Control Group)
Participants with T2DM on a background SGLT-2 inhibitor-based therapy who are prescribed oral antidiabetic drugs (other than Chiglitazar)
Drug: SGLT-2 inhibitor and Other Oral Antidiabetic Drugs (OADs)
Any oral antidiabetic drug (other than Chiglitazar) prescribed by the treating physician as an add-on therapy to an SGLT-2 inhibitor-based regimen.
