Progressive supranuclear palsy (PSP)

Brief summary

European regulatory authority (EMA): Change from baseline to Week 52 in the total score of the full 28-item PSPRS outcome., US regulatory authority (FDA): Change from baseline to Week 52 in the total score of the mPSPRS-10 outcome., Safety endpoints: Safety will be assessed over a treatment period of 52 weeks for the incidence of TEAEs and SAEs, including clinically significant changes in vital signs, clinical laboratory evaluations (including hormone markers in male participants), physical examination findings, ECG parameters, and suicidal ideation/behavior (Columbia Suicide Severity Rating Scale [C SSRS]).
