What This Study Did, in Plain Language

What Was Tested

In this phase 2 trial, researchers set out to test Tirzepatide and Dulaglutide.

It had six arms (groups): Placebo (placebo comparator), one (experimental), one (experimental), one (experimental) and one (experimental).

Tirzepatide placebo and dulaglutide placebo administered subcutaneously (SC) once weekly.

The registry classes the interventions as drug.

Who Took Part

318 actual participants took part.

It was open to people of any sex aged from 18 years up to 75 years.

Healthy volunteers were not accepted; participants needed the condition being studied.

Examples of who could join: Have had type 2 diabetes (T2D) for ≥6 months according to the World Health Organization (WHO) classification. Have a body mass index (BMI) ≥23 and \<50 kilograms per square meter.

How the Study Was Run

Design: randomized, parallel-group and double-blind.

The participants were allocated by chance, so the Tirzepatide group and the comparison group should start out alike.

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

As a double-blind Tirzepatide study, the assignments were hidden from both participants and investigators until the end.

Those kept unaware of assignments: participant and investigator.

It started in 2017-05-24 with completion listed for 2018-08-01.

It ran at 49 sites in United States (35), Poland (6), Slovakia (5) and Puerto Rico (3).

Its stated primary purpose is treatment.

What Was Measured

It also tracked 16 secondary outcomes, for example Change From Baseline to Week 26 in HbA1c, Change From Baseline to Week 12 in HbA1c, Change From Baseline in Body Weight, Change From Baseline in Fasting Blood Glucose, Change From Baseline in High-Density Lipoprotein Cholesterol (HDL-C) and Change From Baseline in Total Cholesterol.

What This Means in Plain Language

Put simply, this is a phase 2, randomized trial of Tirzepatide and Dulaglutide in 318 people.

Our Notes on the Compounds

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

Dulaglutide: A once-weekly GLP-1 receptor agonist (two GLP-1 analog chains joined to an antibody Fc fragment), sold as Trulicity.
