About this study

Official title: A Multiple-Ascending Dose Study in Japanese Patients With Type 2 Diabetes Mellitus to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of LY3298176

The purposes of this study are to determine:

  • The safety of tirzepatide and any side effects that might be associated with it.
  • How much tirzepatide gets into the bloodstream and how long it takes the body to remove it.
  • How tirzepatide affects the levels of blood sugar.

This study includes eight weekly doses of tirzepatide or placebo given as subcutaneous (SC) injections just under the skin. The study will last about 16 weeks (total), including screening and follow-up. This study is for research purposes only and is not intended to treat any medical conditions.

Being tested
Tirzepatide, Placebo
Medical subject headings
Diabetes Mellitus, Type 2

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) Considered by the Investigator to be Related to Study Drug Administration

    Safety was assessed from time of consent through end of study (up to 85 days). Data presented are the number of participants who experienced 1 or more SAEs considered by the investigator to be related to study drug. A summary of SAEs and other non-serious AEs, regardless of causality is located in the Reported Adverse Events section of this record.

    Measured: Baseline through Day 85

Secondary outcomes (3)
  1. Pharmacokinetics (PK): Maximum Observed Concentration (Cmax) of Tirzepatide

    Pharmacokinetics (PK): Maximum observed drug concentration (Cmax) of Tirzepatide in plasma.

    Measured: Predose, 8, 24, 48, 72 and 168 hours post dose for Day 1 administration, and Predose, 8, 24, 48, and 168 hours post dose for Day 50 administration

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

    Area under the concentration versus time curve from time zero to tau (τ) of Tirzepatide (AUC[0- τ]), where tau is dosing interval of (0-168 hours).

    Measured: Predose, 8, 24, 48, 72 and 168 hours post dose for Day 1 administration, and Predose, 8, 24, 48, and 168 hours post dose for Day 50 administration

  3. Pharmacodynamics (PD): Change From Baseline to 8 Weeks in Fasting Plasma Glucose

    Change from baseline to 8 weeks in Fasting Plasma Glucose was measured to investigate the PD effect of Tirzepatide after multiple SC doses administered to Japanese patients with T2DM

    Measured: Baseline, Week 8

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Tirzepatide in people with Type 2 Diabetes Mellitus, run by Eli Lilly and Company at 2 sites in Japan.

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 2 inclusion and 4 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 23 Mar 2023. 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 Japan. 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 23 Mar 2023). 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) Considered by the Investigator to be Related to Study Drug Administration (time frame: Baseline through Day 85). 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 23 Mar 2023.
