Abstract

Developing effective drug treatments for neurodegenerative disorders has always been hamstrung by the accepted inability of large molecules (roughly those with a molecular weight greater than 600 Daltons) to cross the blood-brain barrier (BBB) in therapeutic quantities when administered systemically. The dogma has been that a simple, noninvasive way to accomplish this goal is not possible with many agents, including biologicals, because they are too large. Various novel technologies to breach the BBB have been attempted, but with little success. A randomized double-blind, placebo-controlled clinical trial (RCT) administering a widely used anti-tumor necrosis factor (TNF) biological, etanercept, given via perispinal injection, which bypasses the BBB, turns this dogma on its head. This new trial holds much promise for stroke survivors, as well as having implications for developing treatments based on other large molecules for this and other brain disorders.
