From Barron's 4/2/07 "Essner's company (ticker: WYE) has made a broad investment in Alzheimer's research, bringing 11 drugs into clinical human testing. Its lead compound is a genetically engineered antibody developed with the Irish firm Elan (ADR ticker: ELN) that actually clears away the toxic protein that clots Alzheimer's patients' brains. Other Wyeth compounds inhibit the formation of those Alzheimer's clumps."

From Barron's 4/2/07 "The farthest along of the anti-amyloid experimental drugs are Myriad's Flurizan and Neurochem's Alzhemed, both of which are in the Phase 3 trials that come just prior to seeking FDA approval...The future of Canada's Neurochem basically rides on Alzhemed, an experimental drug that's like an anti-coagulant that binds to single copies of A-beta42 and reduces their tendency to clump together."
