Is Aducanumab for LMICs? Promises and Challenges
Illangage P. C. Gunawardena, Thaarvena Retinasamy, Mohd. Farooq Shaikh. Brain Sciences, 2021-11-22
Topic: Drug trials: efficacy and safety
Aducanumab, a human monoclonal antibody, was approved in June of 2021 as the first disease-modifying treatment for Alzheimer’s disease by the United States Food and Drug Administration (U.S. FDA). A substantial proportion of patients with Alzheimer’s disease live in low- and middle-income countries (LMICs), and the debilitating effects of this disease exerts burdens on patients and caregivers in addition to the significant economic strains many nations bear. While the advantages of a disease-modifying therapy are clear in delaying the progression of disease to improve patient outcomes, aducanumab’s approval by the U.S. FDA was met with controversy for a plethora of reasons. This paper will provide precursory insights into aducanumab’s role, appropriateness, and cost-effectiveness in low- and middle-income countries. We extend some of the controversies associated with aducanumab, including the contradicting evidence from the two trials (EMERGE and ENGAGE) and the resources required to deliver the treatment safely and effectively to patients, among other key considerations.

How this study scored 39/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 22 of the 56 points we could judge it on, which is 39 out of 100.
