Under-Represented Populations Left Out of Alzheimer's Disease Treatment with Aducanumab: Commentary on Ethics

Despite controversy about the efficacy and safety of aducanumab, the FDA's fast-tracking of this medicine is truly historic. However, structural problems leading to socioeconomic disparities and systemic racism in science, healthcare, and society have left out under-represented populations. This perspective outlines the racial and socioeconomic health disparities in aducanumab treatment: 1) Disparities in the risk of Alzheimer's disease (AD), 2) Limited participation from under-represented groups in AD trials raising concerns about the generalizability of the results, 3) Questionable applicability of the amyloid hypothesis in groups under-represented in AD research, and 4) Aducanumab's initial sticker price that unfairly singled out those with lower socioeconomic backgrounds. Potential solutions are discussed.
