NGP 555 has very good brain penetration/absorption, distribution, metabolism, and excretion (ADME) properties. It efficiently crosses the blood-brain barrier, has a brain:plasma ratio of 0.93 (in Tg2576 mice) and shows in vivo efficacy for lowering the biomarker Aβ42 in rodent studies for brain and plasma. Chronic administration of NGP 555 (milled into chow) to Tg2576 mice results in a significant reduction of amyloid plaques.
