What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline to Week 26 in mean 2-hour mixed meal tolerance test (MMTT) stimulated C-peptide concentration

    Mixed meal tolerance test MMTT stimulated C-peptide concentration is to be calculated from area under the concentration-time curve (AUC)

    Measured: From Baseline to Week 26

Secondary outcomes (15)
  1. Change from baseline to Week 52 in mean 2-hour MMTT stimulated Cpeptide concentration

    MMTT stimulated C-peptide concentration is to be calculated from area under the concentration-time curve (AUC)

    Measured: From Baseline to Week 52

  2. Participant remaining C-peptide positive at Week 26 and Week 52

    Incidence (yes/no) outcome Defined as mean 2-hour MMTT stimulated C-peptide concentration ≥0.2 nmol/L

    Measured: Week 26 and Week 52

  3. Time in range (TIR) (70-180 mg/dL) at Week 26 and Week 52

    Assessed by Continuous glucose monitoring (CGM). A CGM system is a device that records interstitial glucose levels continuously throughout the day and night via a subcutaneous sensor.

    Measured: Week 26 and Week 52

  4. Change from baseline to Week 26 and Week 52 in insulin dose

    Expressed in IU/kg/day

    Measured: From Baseline to Week 26 and Week 52

  5. Change from baseline to Week 26 and Week 52 in glycated hemoglobin A1c (HbA1c) level

    Measured: From Baseline to Week 26 and Week 52

  6. Participant having HbA1c ≤6.5% and ≤0.25 IU/kg/day of exogenous insulin required at Week 26 and Week 52

    Incidence (yes/no) outcome

    Measured: Week 26 and Week 52

  7. Incidence of treatment emergent adverse events (TEAEs), serious adverse events (SAEs), adverse events of special interest (AESIs) and TEAEs leading to treatment discontinuation

    Measured: Up to End of Study (approx. 83 Weeks)

  8. Incidence (yes/no) of hypoglycemic events (level 2 or 3 according to American Diabetes Association)

    Incidence (yes/no) outcome

    Measured: Up to End of Study (approx. 83 Weeks)

  9. Incidence (yes/no) of hyperglycemic episodes (level 2 according to American Diabetes Association)

    Incidence (yes/no) outcome

    Measured: Up to End of Study (approx. 83 Weeks)

  10. Incidence (yes/no) of diabetic ketoacidosis (DKA) events

    Incidence (yes/no) outcome

    Measured: Up to End of Study (approx. 83 Weeks)

  11. Incidence (yes/no) of clinically significant changes in vital signs, electrocardiogram (ECG), and/or laboratory evaluation

    Incidence (yes/no) outcome

    Measured: Up to End of Study (approx. 83 Weeks)

  12. Brivekimig serum concentrations over time

    Measured: Up to End of Study (approx. 83 Weeks)

  13. Incidence of anti-drug antibodies (ADAs) over time

    Measured: Up to End of Study (approx. 83 Weeks)

  14. Change from baseline to Week 26 and Week 52 in Problem Areas in Diabetes (PAID) total score (all participants)

    The Problem Areas in Diabetes (PAID) is a diabetes specific instrument measuring diabetes distress. There is an adult version (18+) and a pediatric version for children 8-17 years of age. The PAID contains 20 items that describe negative emotions related to diabetes (eg, depression, anger, frustration). Item scores are summed to generate a total score. Scores range from 0 to 100, where higher total scores correspond to higher emotional distress due to diabetes

    Measured: From Baseline to Week 26 and Week 52

  15. Change from baseline to Week 26 and Week 52 in PAID immediate and theoretical domain scores (caregivers of all participants 12 to 17 y.o.)

    Caregiver version of PAID for parents with children 8-18 years of age consists of 18 items that measure caregiver burden. Two scores are calculated: Immediate Burden and Theoretical Burden. Scores range from 0 to 100, where higher scores correspond to greater caregiver burden.

    Measured: From Baseline to Week 26 and Week 52

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Brivekimig in people with Type 1 Diabetes Mellitus, run by Sanofi at 24 sites in 8 countries.

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 20 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: under way, not looking for participants, as of the sponsor's last update on 13 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in United States, Argentina, Australia, Chile, Israel and 3 more countries. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline to Week 26 in mean 2-hour mixed meal tolerance test (MMTT) stimulated C-peptide concentration (time frame: From Baseline to Week 26). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Mar 2026.
