Safety Study of Passive Immunization for Patients With Mild to Moderate Alzheimer's Disease

May 8, 2012 updated by: Pharmacology Research Institute

A Phase IIA, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Multiple Ascending Dose, Safety, Tolerability, Pharmacokinetic, Pharmacodynamic, and Immunogenicity Trial of AAB-001 in Patients With Mild to Moderate AD

This research study will assess whether AAB-001 is safe, well tolerated and effective for use in patients with Alzheimer's Disease. AAB-001 is a new drug that is not available outside this study. AAB-001 is an antibody (a type of protein usually produced by white blood cells to destroy other substances in the body). In Alzheimer's disease a protein called amyloid gathers in the brain and is thought to cause symptoms like memory loss and confusion. It is hoped that AAB-001 will attach to the amyloid protein in your brain and help your body to remove it.
