Davunetide (NAP)

NAP · NAPVSIPQ · AL-108 · AL-208

ADNP-derived microtubule-stabilizing octapeptide. Phase 2/3 PSP trial failed primary endpoint; orphan drug designation retained for ADNP syndrome.

§ 01   Overview

Overview

ADNP-derived microtubule-stabilizing octapeptide. Phase 2/3 PSP trial failed primary endpoint; orphan drug designation retained for ADNP syndrome.

PSP Phase 2/3 (Boxer 2014) failed primary. Continuing development in ADNP syndrome.

§ 02   Mechanism

Mechanism of action

Davunetide (NAPVSIPQ) is the active fragment of Activity-Dependent Neuroprotective Protein (ADNP). It binds EB1/EB3 to stabilize microtubules and reduces tau hyperphosphorylation.

  • 01Microtubule stabilization
  • 02Tau reduction in preclinical models
  • 03Orphan designation for ADNP syndrome
