Research Overview

Neuropeptide S

Animal studies suggest NPS can reduce anxiety-like behavior while altering wakefulness and alertness through the NPS receptor system. Human cognitive data are very limited, and it has no approved clinical indication.

BI 456906

Preclinical and early clinical research support meaningful metabolic effects with a tolerable safety profile. It remains investigational and is not commercially available.
