Contextual Considerations and Recommendations for Estimating the Value of Alzheimer's Disease Therapies

The pipeline for new treatments for Alzheimer's disease (AD) in the USA contains over 100 different agents, 80% of which can be categorized as disease-modifying therapies. The regulatory approval of the disease-modifying agent aducanumab has brought more attention to the complexity of the diagnosis, evaluation, and treatment of AD and the difficult decisions payers and policy makers will face over the next few years as innovation continues in this space. The value of AD treatment can vary widely according to the perspective of the analysis, sources of data, and methodological approach for the value assessment. This article focuses on AD-specific data gaps and measurement challenges and provides guidance for evidence generation to facilitate better value assessments for future AD treatments.
