This study includes 3 parts (A, B and C). Part A involves a single dose of tirzepatide taken as a subcutaneous (SC) injection just under the skin and will be approximately 10 weeks in duration, including screening. Parts B and C involve 4 doses of tirzepatide taken once weekly (over 4 weeks) as a SC injection just under the skin and is approximately 12-14 weeks in duration, including screening. Each participant will enroll in only one part.

This study is for research purposes only, and is not intended to treat any medical condition.

What is being measured

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

  1. Number of Participants With One or More Serious Adverse Event(s) (SAEs)

    Number of participants with one or more SAEs considered by the investigator to be related to study drug administration. A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, were reported in the Reported Adverse Events module

    Measured: Baseline through Day 43 (Part A) and Day 57 (Part B and C)

Secondary outcomes (5)
  1. Pharmacokinetics (PK): Area Under the Concentration Versus Time Curve (AUC) of Tirzepatide in Part A.

    Area under the concentration versus time curve from zero to infinity (AUC [0-∞]) of Tirzepatide in Part A.

    Measured: Predose, 8hours(h), 24h,48h,72h,96h,120h,168h,336h postdose, day 29, day 43

  2. Pharmacokinetics (PK): Area Under the Concentration Versus Time Curve (AUC) of Tirzepatide in Part B

    Area under the concentration versus time curve during 1 dosing interval (AUC [0-τ]) of Tirzepatide in Part B. τ equals 168 hours.

    Measured: Predose, 8hours(h), 24h,48h,72h,168h postdose

  3. Pharmacokinetics (PK): Area Under the Concentration Versus Time Curve (AUC) of Tirzepatide in Part C

    Area under the concentration versus time curve during 1 dosing interval (AUC [0-τ]) of Tirzepatide in Part C. τ equals 168 hours.

    Measured: Predose, 8hours(h), 24h,48h,72h,168h postdose

  4. Pharmacodynamics (PD): Ratio of AUC of Glucose on Day 2 to Baseline (Part C)

    PD: Glucose area under the concentration versus time curve from time 0 to 2 hours (AUC[0-2h]) in Part C. Ratio to Baseline (Day -1) AUC (0-2h).

    Measured: Pre-glucose dose, 0.5, 1, 1.5, 2 hours post-glucose dose on Day -1 and Day 2

  5. Pharmacodynamics (PD): Ratio of AUC of Glucose on Day 23 to Baseline (Part C)

    PD: Glucose area under the concentration versus time curve from time 0 to 2 hours (AUC[0-2h]) in Part C. Ratio to Baseline (Day -1) AUC (0-2h).

    Measured: Pre-glucose dose, 0.5, 1, 1.5, 2 hours post-glucose dose on Day -1 and Day 23

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Tirzepatide and Dulaglutide in people with Healthy and Type 2 Diabetes Mellitus (T2DM), run by Eli Lilly and Company at 2 sites in 2 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 3 inclusion and 7 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: finished, as of the sponsor's last update on 16 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Singapore. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Jan 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With One or More Serious Adverse Event(s) (SAEs) (time frame: Baseline through Day 43 (Part A) and Day 57 (Part B and C)). 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 NCT02759107, which also lists 1 linked publication.

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 16 Jan 2024.
