Lanabecestat (formerly known as AZD3293 or LY3314814) is an oral beta-secretase 1 cleaving enzyme (BACE) inhibitor. A BACE inhibitor in theory would prevent the buildup of beta-amyloid and may help slow or stop the progression of Alzheimer’s disease.

In September 2014, AstraZeneca and Eli Lilly and Company announced an agreement to co-develop lanabecestat.^[1] A pivotal Phase II/III clinical trial of lanabecestat started in late 2014 and is planned to recruit 2,200 patients and end in June 2019.^[2] In April 2016 the company announced it would advance to phase 3 without modification.^[3]
