Description

Semagacestat, also known as LY450139 or LY4501; was a candidate drug for a causal therapy against Alzheimer’s disease. It was originally developed by Eli Lilly and Ãlan, and clinical trials were conducted by Eli Lilly. Phase III trials included over 3000 patients, but in August 2010, a disappointing interim analysis, in which semagacestat performed less well than the placebo, led to investigators being instructed to tell subjects to stop taking the drug.
