So it began one other giant trial specializing in mildly impaired sufferers within the early phases of Alzheimer's.
However on Wednesday, the corporate mentioned in a information launch that though a few of the results regarded promising, "sufferers handled with solanezumab didn't expertise a statistically vital slowing in cognitive decline in comparison with sufferers handled with placebo."
John C. Lechleiter, Lilly's chairman, president and chief government officer, mentioned within the assertion, "we're disillusioned for the thousands and thousands of individuals ready for a possible disease-modifying therapy for Alzheimer's illness," including, "We are going to consider the impression of those outcomes on the event plans for solanezumab and our different Alzheimer's pipeline belongings."
