About this trial

Prediabetes affects millions of adults worldwide and carries a high risk of progression to type 2 diabetes. Mazdutide is a once-weekly injectable drug that activates both GLP-1 and glucagon receptors, lowering blood sugar and body weight simultaneously.

This study (DREAM-PRE) tests whether mazdutide can help adults with prediabetes return to normal blood sugar levels. Approximately 150 adults aged 18-75 years with prediabetes and BMI ≥22 kg/m² will be randomly assigned in equal numbers to one of three groups: mazdutide 4 mg once weekly, mazdutide 6 mg once weekly, or placebo once weekly. All participants also receive standardized diet and exercise guidance throughout the study.

Treatment lasts 24 weeks, followed by 24 weeks of off-drug follow-up to see whether any benefits are maintained. The main question is: what proportion of participants achieve completely normal blood sugar (normal HbA1c, fasting glucose, AND glucose tolerance test) after 24 weeks of treatment? The study is conducted at approximately 10 hospitals across China.

Eligibility criteria

Qualifiers

Voluntarily signed written informed consent prior to any study procedures

Age 18 to 75 years (inclusive) at the time of signing informed consent; male or female

Impaired Glucose Tolerance (IGT): 75g OGTT 2-hour plasma glucose

7.8 mmol/L and <11.1 mmol/L

Disqualifiers

Confirmed diabetes at screening (FPG ≥7.0 mmol/L, OGTT 2h-PG ≥11.1 mmol/L, or HbA1c ≥6.5%); or prior confirmed diagnosis of type 1 diabetes, type 2 diabetes, or other specific types of diabetes. Prior gestational diabetes in whom blood glucose has returned to prediabetes levels after delivery is NOT grounds for exclusion.

Continuous use of any antidiabetic medication for more than 7 days within 3 months prior to screening, including: biguanides (metformin), alpha-glucosidase inhibitors (acarbose, voglibose, miglitol), sulfonylureas (glimepiride, gliclazide, glipizide, glibenclamide), glinides (repaglinide, nateglinide), thiazolidinediones (pioglitazone, rosiglitazone), DPP-4 inhibitors (sitagliptin, saxagliptin, vildagliptin, linagliptin, alogliptin), SGLT2 inhibitors (dapagliflozin, empagliflozin, canagliflozin, ertugliflozin), insulin (any formulation), or traditional Chinese medicine with confirmed glucose-lowering indication.

Use of any of the following within 6 months prior to screening (regardless of duration): GLP-1 receptor agonists (semaglutide, liraglutide, dulaglutide, exenatide, lixisenatide, benaglutide, etc.), GIP/GLP-1 dual agonists (tirzepatide, etc.), any dual or triple agonist containing GLP-1R and/or GCGR components (including mazdutide), or any GLP-1 class investigational drug in clinical development.

Use of any prescription weight-loss medication within 3 months prior to screening (regardless of duration), including orlistat, naltrexone/bupropion combination, phentermine/topiramate combination, or any weight-loss drug approved in China or in clinical development. Over-the-counter dietary supplements are not excluded but must be recorded.
