Bapineuzumab
Bapineuzumab (nicknamed "bapi") is a humanized monoclonal antibody that acts on the nervous system and may have potential therapeutic value for the treatment of Alzheimer's disease and possibly glaucoma. However, in 2012 it failed to produce significant cognitive improvements in patients in two major trials, despite lowering key biomarkers of AD, amyloid brain plaque and hyperphosphorylated tau protein in CSF.

Bapineuzumab has been shown to recognise the extreme N-terminal 5 residues of Aβ peptide in a helical conformation (4HIX.pdb) stabilized by internal hydrogen bonds involving the first three amino acids.
Bapineuzumab is an antibody to the beta-amyloid (Aβ) plaques that are believed to underlie Alzheimer's disease neuropathology. In previous clinical trials for vaccination against human beta amyloid, called AN-1792, patients with Alzheimer's disease using active immunization had positive outcomes with removal of plaques, but 6% of subjects developed aseptic meningitis and the trial was stopped.
