Measuring what participants report, not only what is weighed

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Patient-reported outcome instruments ask participants to rate aspects of their own functioning and wellbeing using validated questionnaires. In obesity trials, physical function and weight-related quality of life are the usual domains. Several class trials have reported improvements alongside weight loss. For retatrutide, such measures belong to the phase 3 programme rather than the published phase 2 papers.

What the instruments are

Standardised questionnaires, validated to show they measure what they claim consistently and sensitively, with domains such as physical function, self-esteem and public distress. Scores are compared between arms like any other endpoint. Regulators accept them as secondary endpoints when properly validated and pre-specified.

They capture something a scale cannot: whether the person feels and functions differently.

What the class has shown

Large phase 3 trials of approved agents have reported improvements in physical function and weight-related quality-of-life scores alongside weight reduction, with the size of improvement tracking the weight change. These are secondary endpoints and are read as such.

They are among the measures that connect a weight figure to a lived outcome.

For retatrutide

The phase 2 papers focus on weight, glycaemia and cardiometabolic markers. Patient-reported outcomes are standard in phase 3 programmes and are expected in the TRIUMPH publications; this page reports none until they are published.
