Human evidence record

What this study tells us

Participants were assigned to comparison groups by chance, usually with placebo and/or blinding to reduce bias. This is a strong design for testing cause and effect, but the population, duration and endpoints still limit what can be concluded.

Who was studied?

Adults with obesity or overweight plus a weight-related condition

How many?

n=338

What happened?

Dose-dependent weight reduction; highest-dose groups produced very large mean reductions over 48 weeks.

What stops us overclaiming?

Phase 2 duration; investigational product; no long-term outcomes; cross-trial comparisons are inappropriate.
