Alzheimer's disease (AD) drug development is limited by the presence of the blood-brain barrier (BBB). More than 98% of all small molecule drugs, and ∼100% of all large molecule drugs, do not cross the BBB. Despite the fact that the vast majority of AD drug candidates do not cross the BBB, the present-day AD drug development effort is characterized by an imbalance, whereby >99% of the drug development effort is devoted to CNS drug discovery, and <1% of drug development is devoted to CNS drug delivery. Future AD drug development needs a concerted effort to incorporate the BBB sciences early in the CNS drug discovery process. This can be accomplished by a reallocation of resources, and an expansion of the effort in the pure science of BBB biology and the applied science of brain drug targeting technology.
