About this study
Official title: Efficacy and Safety of Mazdutide in Adults With Prediabetes: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Clinical Trial (DREAM-PRE)
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.
Read the detailed description
BACKGROUND AND RATIONALE Prediabetes - encompassing impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and elevated HbA1c (5.7-6.4%) - affects an estimated 352 million adults globally, with China bearing the highest absolute burden. Without intervention, approximately 5-10% of individuals with prediabetes progress to type 2 diabetes (T2D) annually. Reversal to Normal Glucose Regulation (NGR) is achievable but underexplored as a primary clinical endpoint.
Mazdutide (IBI362) is a GLP-1 receptor/glucagon receptor (GLP-1R/GCGR) dual agonist. Beyond GLP-1R-mediated glucose-dependent insulin secretion and appetite suppression, GCGR co-agonism enhances hepatic fatty acid oxidation and energy expenditure. This dual mechanism may address the overlapping pathophysiology of prediabetes - beta-cell dysfunction, insulin resistance, ectopic lipid accumulation, and excess adiposity - more comprehensively than GLP-1R monoagonists alone.
SCIENTIFIC RATIONALE FOR DOSE SELECTION Two maintenance doses are evaluated: 4 mg and 6 mg once weekly. Both doses demonstrated clinically meaningful HbA1c reduction and weight loss in prior trials (DREAMS-1, DREAMS-2) in patients with type 2 diabetes. The 4 mg dose represents a potentially efficacious and better-tolerated option, while the 6 mg dose achieves maximal receptor engagement. Comparing both doses against placebo in a prediabetes population allows dose-response characterization and informs optimal dosing for future prevention trials.
DISEASE MODIFICATION HYPOTHESIS The primary endpoint (NGR at Week 24) captures complete metabolic normalization across three glycemic domains simultaneously. Secondary assessment at Week 48 (24 weeks after treatment discontinuation) tests whether treatment induces durable disease modification - restoration of beta-cell function and insulin sensitivity - rather than pharmacological glucose suppression alone. The Disposition Index (product of insulin secretion and insulin sensitivity) serves as the key mechanistic secondary endpoint.
LIFESTYLE INTERVENTION BACKGROUND All participants receive standardized lifestyle intervention consistent with Chinese guidelines for prediabetes management, providing an active background that reflects real-world clinical practice and enhances external validity.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Mazdutide and Standardized Lifestyle Intervention in people with Prediabetes and Impaired Fasting Glucose, run by Shandong Provincial Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 17 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jiajun Zhao, MD, PhD (0531-68776025, jjzhao@sdu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of Participants Achieving Normal Glucose Regulation (NGR) at Week 24 (time frame: Week 24). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07654062, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jun 2026.
