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 underrepresented 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.
