A 2-hour infusion of 0.1 to 10 mg/kg ponezumab was well tolerated in subjects with mild-to-moderate AD. Plasma pharmacokinetic profile was approximately linear. Plasma Aβ increased with dose, and CSF Aβ increased at the highest dose, suggesting that intravenous ponezumab alters central Aβ levels.

Administration of ponezumab as a 10-minute infusion was safe and well tolerated and produced effects on plasma Aβ species comparable with a 2-hour infusion. Shorter infusions may provide more flexibility, comfort, and convenience for patients and caregivers.
