In lat­est set­back, As­traZeneca’s high hopes for its lu­pus drug an­i­frol­um­ab crushed by a PhI­II fail­ure

The last of the late-stage au­toim­mune drugs still left at As­traZeneca just went down to a sting­ing de­feat in Phase III.

The phar­ma gi­ant didn’t waste any time with its state­ment. Their drug an­i­frol­um­ab — which they once held high hope of suc­cess for — failed the pri­ma­ry end­point for lu­pus: sig­nif­i­cant­ly re­duc­ing dis­ease ac­tiv­i­ty for pa­tients with sys­temic lu­pus ery­the­mato­sus.

This is the first of two Phase III stud­ies for this an­ti­body, which tar­gets type I in­ter­fer­ons in­clud­ing IFN-α, IFN-β and IFN-ω. But with the first big, 52-week tri­al a flop, the whole pro­gram — in­clud­ing two oth­er mid-stage tri­als — have just come un­der a very dark cloud.
