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.

Conditions

  • Prediabetes
  • Impaired Fasting Glucose
  • Impaired Glucose Tolerance (Prediabetes)

Interventions

DRUG

Mazdutide

GLP-1 receptor/glucagon receptor (GLP-1R/GCGR) dual agonist, administered by subcutaneous injection once weekly using a pre-filled pen device. Arm 1 (4 mg): titration from 2 mg QW (weeks 0-4) to 4 mg QW (weeks 5-24). Arm 2 (6 mg): titration from 2 mg QW (weeks 0-4) to 4 mg QW (weeks 5-8) to 6 mg QW (weeks 9-24). Injection sites: abdomen, anterior-lateral thigh, or lateral upper arm, rotated at each injection.

DRUG

Placebo

Matching placebo for mazdutide, administered by subcutaneous injection once weekly using a pre-filled pen device identical in appearance, color, volume, and packaging to the active drug pen. Titration schedule mirrors the 6 mg mazdutide arm to maintain blinding.

BEHAVIORAL

Standardized Lifestyle Intervention

Structured dietary modification with an energy deficit of 500-750 kcal/day and moderate-intensity aerobic exercise of at least 150 minutes per week, maintained throughout the 48-week study period. Applied equally to all three arms.
