Plasma P‐tau217 for detecting amyloid clearance after donanemab in Alzheimer's disease
This analysis of the phase 3 TRAILBLAZER‐ALZ 2 trial examined whether plasma tau protein phosphorylated at threonine 217 (p‐tau217) level can reliably monitor treatment‐related amyloid clearance (TRAC) after donanemab treatment in early symptomatic Alzheimer's disease (AD).
