This multicenter, randomized, double-blind, placebo-controlled trial aims to evaluate the efficacy and safety of Chiglitazar Sodium combined with lifestyle intervention for reversing prediabetes to normal glucose metabolism. Eligible participants with prediabetes will be randomized 1:1 to receive either Chiglitazar Sodium 48 mg once daily or matching placebo, both combined with standardized lifestyle intervention, for 52 weeks, followed by a 12-week observation period and optional long-term extension. The primary endpoint is the reversion rate to normal glucose metabolism at week 64. Secondary endpoints include progression to type 2 diabetes, glycemic control, lipid profile, blood pressure, UACR, HOMA-IR, HOMA-β, body weight, BMI, and waist-to-height ratio. Exploratory endpoints include inflammatory markers and long-term cardiovascular outcomes. Safety endpoints include adverse events, vital signs, ECG, and laboratory parameters.
Prediabetes is an intermediate state of hyperglycemia that precedes the development of type 2 diabetes. Reversing prediabetes to normal glucose metabolism represents a promising strategy for diabetes prevention. Chiglitazar Sodium is a novel PPAR pan-agonist with potential benefits on glycemic control and metabolic parameters.
This national multicenter study will be conducted across 30 sites in China. A total of 472 participants aged 18-70 years with prediabetes (according to Chinese expert consensus criteria, including IFG, IGT or IFG+IGT) and BMI 20-32 kg/m² will be enrolled.
The study consists of four phases:
Screening Period (up to 2 weeks): Assessment of eligibility including OGTT, laboratory tests, and medical history.
Double-Blind Treatment Period (52 weeks): Eligible participants are randomized 1:1 to receive either Chiglitazar Sodium 48 mg once daily or matching placebo, both combined with standardized lifestyle intervention (diet and exercise according to Chinese Diabetes Prevention Guidelines). Study visits occur at weeks 4, 12, 24, 36, and 52.
Observation Period (12 weeks, weeks 53-64): Participants who have not developed diabetes enter a 12-week drug-free observation period, with final assessment at week 64.
Extension Period (up to week 156): Participants who have not developed diabetes and provide consent may continue follow-up for long-term cardiovascular outcomes assessment at weeks 104 and 156.
The primary endpoint is the proportion of participants achieving reversion to normal glucose metabolism at week 64. Secondary endpoints include progression to type 2 diabetes, changes in fasting plasma glucose, OGTT (1h/2h PPG), HbA1c, lipid profile (TG, TC, LDL-C, HDL-C), blood pressure, UACR, HOMA-IR, HOMA-β, body weight, BMI, and waist-to-height ratio. Exploratory endpoints include changes in inflammatory markers (hsCRP, IL-6, TNF-α) and incidence of heart failure, non-fatal myocardial infarction, non-fatal stroke, cardiovascular death, or all-cause death through week 156. Safety will be monitored throughout.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
