Eli Lil­ly fi­nal­ly pub­lished its dis­as­trous EX­PE­DI­TION3 da­ta, a cost­ly les­son in re­think­ing Alzheimer's

Eli Lil­ly $LLY had hoped that EX­PE­DI­TION3 would prove to the world that amy­loid be­ta was the cause of Alzheimer’s and that solanezum­ab could bend the curve of cog­ni­tive de­cline back to pa­tients’ fa­vor — or at least for pa­tients with an ear­ly-stage, mild form of the dis­ease.

In­stead, the land­mark fail­ure — ac­knowl­edged well over a year ago — is rais­ing fresh ques­tions about whether in­ves­ti­ga­tors have been aim­ing at the wrong tar­get for more than a decade of flops and dis­as­trous fail­ures.
