Lilly Changes Alzheimer Study Endpoint
Lilly is changing the primary endpoint of its EXPEDITION3 clinical trial of its solanezumab in people with mild Alzheimer’s dementia. The company says that the original study design included co-primary endpoints of cognition and function. With emerging scientific evidence supporting the idea that cognitive decline precedes and predicts functional decline in Alzheimer’s disease, particularly in the early stages of the disease, Lilly is amending the trial to include a single primary endpoint of cognition. Functional outcomes will still be measured, the company says, and will be considered two secondary endpoints.
“It is important to note that the endpoint change affects the study’s data analysis plan, but it does not affect anything related to the actual conduct of the trial,” a company statement says. “Lilly will continue to remain blinded to study data until after the database lock occurs in the fourth quarter of 2016. Lilly understands that regulators globally will continue to view both cognitive and functional endpoints as necessary for clinical trials in people with mild Alzheimer’s dementia, and regulatory guidance has been to include these as co-primary endpoints. Lilly is submitting the EXPEDITION3 amendment to all appropriate regulatory authorities.
