Davunetide — living evidence map

The Atlas page holds the claims; this is how its evidence evolved.

Summary

Davunetide (NAP, AL-108) is an intranasal peptide that stabilized microtubules and reduced tau phosphorylation in preclinical studies; in a 52-week phase 2/3 trial in 313 people with progressive supranuclear palsy it did not differ from placebo on either primary measure. · pmid:24873720

In a 12-week trial in 63 people with schizophrenia, davunetide did not significantly change cognition against placebo but improved a measure of functional capacity. · pmid:22169248
