Now a three-time los­er, selume­tinib con­tin­ues to cause headaches as As­traZeneca dumps a failed PhI­II

Selume­tinib con­tin­ues to cause big headaches at As­traZeneca $AZN.

The MEK in­hibitor — now part­nered with Mer­ck $MRK in their big $8.5 bil­lion al­liance — failed a Phase III study for dif­fer­en­ti­at­ed thy­roid can­cer, ac­cord­ing to the Q2 re­port from As­traZeneca. And they qui­et­ly whisked that pro­gram out of the pipeline in a vir­tu­al foot­note to its quar­ter­ly re­port.

The fail­ure makes this drug a three-time los­er, though it’s still in clin­i­cal tri­als.
