What made Glax­o­SmithK­line’s Hal Bar­ron spend $2.2B to get back in­to neu­ro? Alec­tor flash­es the da­ta

What made GSK’s Hal Bar­ron spend $700 mil­lion cash to get in on a pair of an­ti­bod­ies for neu­rode­gen­er­a­tion?

Alec­tor flashed part of the an­swer Thurs­day, de­tail­ing ear­ly da­ta from their lead drug in a ge­net­ic and rapid­ly pro­gress­ing form of de­men­tia. Al­though it comes on­ly from a hand­ful of pa­tients in a sin­gle-arm tri­al, it pro­vides — af­ter near­ly a decade — one of the first hints at proof-of-con­cept for the ap­proach that not on­ly won Alec­tor a lu­cra­tive phar­ma part­ner­ship but al­so a uni­corn val­u­a­tion at a time when near­ly every­thing in neu­rode­gen­er­a­tion had failed.
