Factbox-Roche's drug failure extends long list of Alzheimer's trial setbacks
(Reuters) -Roche Holding AG reported on Monday that its Alzheimer's drug candidate, gantenerumab, did not meet main goals of studies, marking another setback for companies trying to find an effective treatment for the memory-robbing disease.
The results come nearly two months after partners Eisai Co Ltd and Biogen Inc reported that their Alzheimer's disease drug, lecanemab, significantly slowed cognitive decline in a large trial.
