About this study

Official title: Type 1 Diabetes Intervention With Mazdutide for Efficacy, Safety and Cardiovascular Protection (The TIMES Trial Program-TIMES-EFFICACY & TIMES-CV

This study is a multicenter, randomized, double-blind, placebo-controlled clinical trial in patients with type 1 diabetes (T1D), conducted in two stages.

Stage 1 is the efficacy and safety assessment (TIMES-EFFICACY). A total of 182 T1D patients who meet the inclusion criteria will be randomized in a 1:1 ratio to two groups: one receiving mazdutide and the other receiving placebo. The follow-up period is 16 weeks. The primary clinical endpoint is the proportion of patients achieving time in range (TIR) >70% with time below range (TBR) <4%. An interim analysis will be performed at Week 8; if the absolute TBR in the mazdutide group increases by more than 5% relative to the placebo group, the subsequent study will be terminated.

Stage 2 is the cardiovascular protective effect assessment (TIMES-CV). During the Stage 1 efficacy and safety assessment, a pre-specified stratification method will ensure that 104 patients with high cardiovascular risk factors are randomized in a 1:1 ratio to the mazdutide group or the placebo group. After completing the 16-week efficacy and safety assessment, these 104 subjects will continue to receive randomized controlled treatment and enter the cardiovascular effect assessment stage, with a total follow-up duration of 52 weeks. The primary clinical endpoint is the change in non-calcified coronary artery plaque volume.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MazdutideDrug

    Mazdutide is a synthetic peptide analog of mammalian oxyntomodulin and a once-weekly dual agonist of the glucagon-like peptide-1 receptor (GLP-1R) and the glucagon receptor (GCGR), under development for the treatment of obesity and type 2 diabetes (T2D). Mazdutide has been shown to induce significant weight loss in patients with obesity and to help improve glycemic control in patients with T2D.

  • PlacboDrug

Study groupRoleWhat they receive
mazdutide groupExperimentalParticipants in the treatment group will receive mazdutide by subcutaneous injection once weekly. The dose will be escalated stepwise according to a pre-defined regimen from a safe starting dose to an effective maintenance dose (from 2 mg to 4 mg) over several weeks, with dose reduction permitted if needed.

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 18 inclusion and 13 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 9 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

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.

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 Chu Lin, M.D. (+86 18811792075, chulin@bjmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of the participants achieving time in range (TIR)>70 and time below range (TBR)<4% (TIMES-EFFICACY) (time frame: From baseline to 16 weeks). The study lists 2 primary outcomes in all. 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 NCT07924553, which also lists 6 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?
