Mazdutide for Adults With Prediabetes: A Randomized, Double-Blind, Placebo-Controlled Trial (DREAM-PRE)
China150 participantsStarted 2026-07
Plain-language summary
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.

Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Proportion of Participants Achieving Normal Glucose Regulation (NGR) at Week 24
. 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.
. Spontaneous body weight change ≥10% within 3 months prior to screening (based on self-report and/or available medical records), or currently participating in any organized weight-loss program (including commercial weight-loss plans or weight-loss interventions in other clinical trials).
. Prior bariatric or metabolic surgery including Roux-en-Y gastric bypass, sleeve gastrectomy, adjustable gastric banding, biliopancreatic diversion, intragastric balloon placement, or other bariatric surgery.
. Prior history of acute pancreatitis (confirmed by imaging or surgery) or chronic pancreatitis; or serum amylase \>3× ULN or serum lipase \>3× ULN at screening.
. Personal history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia type 2 (MEN2); first-degree family history of MTC or MEN2; or serum calcitonin ≥50 ng/L at screening.
