The mouse keeps its own notebook
Animal stage · 2022 discovery paper
What changed in mice—and what stays a mouse finding?
Subject One draws an enormous arrow from a mouse enclosure to a human silhouette. Doctide erases the arrow. The mouse keeps exploring. Subject One labels two separate notebooks and finally leaves room between them.
What changes here
Mouse weight loss supported further investigation; it did not establish the same effect in people. [1]

Diet-induced obese mice
Repeated subcutaneous BI 456906 was compared with vehicle and semaglutide. Weight fell alongside changes in food intake and energy expenditure. Lean mass also declined at some tested regimens. These are preclinical mouse experiments, not human efficacy or muscle-preservation results; no clinical phase or NCT applies. [1]
A separate research record
The accompanying mouse study deposited molecular-expression data in GEO as GSE211105. Dataset release dates do not identify when every animal experiment began. [2]
What this does not establish
This selected efficacy record is not a complete mortality or toxicology account. No absence of animal deaths, tumors or long-term harm is inferred from incomplete reporting.
