What This Study Did, in Plain Language

What Was Tested

In this phase 1 trial, researchers set out to test Tirzepatide.

The purpose of this study is to assess how fast tirzepatide gets into the blood stream and how long it takes the body to remove it in participants with impaired liver function compared to healthy participants.

The study will last about two months and will include five visits to the study center.

It had four arms (groups): Normal Hepatic Function (active comparator), Mild Hepatic Impairment (experimental), Moderate Hepatic Impairment (experimental) and Severe Hepatic Impairment (experimental).

The registry classes the interventions as drug.

Who Took Part

Enrollment: 32 actual participants took part.

It was open to people of any sex aged from 18 years up to 85 years.

Healthy volunteers could join, not only people with the condition.

Examples of who could join: Women of childbearing potential are excluded from the study. Are between the body mass index (BMI) of 19.0 and 40.0 kilograms per meter squared (kg/m²), inclusive, at screening. Males or females with chronic mild, moderate and severe liver impairment, assessed by Child-Pugh scoring.

How the Study Was Run

Design: non-randomized, parallel-group and open-label.

The Tirzepatide group and the comparison group ran side by side rather than switching.

Being open-label, the Tirzepatide study did not mask who received what.

It started in 2019-07-22 with completion listed for 2020-09-22.

It ran at 3 sites in United States (3).

Its stated primary purpose is basic science.

What Was Measured

Researchers chose this as the main measure: PK: Maximum Observed Drug Concentration (Cmax) of Tirzepatide.

What This Means in Plain Language

Put simply, this is a phase 1, non-randomized trial of Tirzepatide in 32 people.

Its size is small, so on its own it can only give an early look.

The trial is marked completed; results are posted on the registry, and this page does not restate them.

Our Notes on the Compound

Tirzepatide: A prescription peptide medicine that acts on both the GIP and GLP-1 receptors; Mounjaro and Zepbound contain the same active ingredient.
