Lecanemab: A Second in Class Therapy for the Management of Early Alzheimer's Disease
Yoon CH, Groff C, Criss O.. Innovations in pharmacy, 2024-03-18
Topic: Drug trials: efficacy and safety
The Food and Drug Administration granted traditional approval of lecanemab for the treatment of Alzheimer's disease (AD). Lecanemab is a humanized anti-amyloid monoclonal antibody directed towards Aβ protofibrils. Lecanemab is the only drug that targets Aβ soluble protofibrils and has shown statistical differences in mild AD or mild cognitive impairment. In its landmark phase III trial, lecanemab was shown to slow the progression of clinical decline, and a reduction in amyloid protein accumulation. The difference in mean CDR-SOB score improvement between the treatment and placebo groups was -0.45, of which the clinical significance could be argued. Amyloid burden was also considerably reduced as well, but the true clinical consequence of this reduction remains to be seen. This beneficial impact on daily living is offset by rare but serious side effects including amyloid-related imaging abnormalities (ARIA) causing cerebral edema (ARIA-E) or cerebral microhemorrhages or hemosiderin deposits (ARIA-H). Benefits of therapy must be considered against the risk of cerebral microhemorrhages and edema. Affordability must also be taken into consideration. The current estimated yearly cost for twice monthly lecanemab infusion is $26,500. In addition to the significant cost challenges, the frequent infusions may pose concerns related to access. Additional agents within this class are in the pipelines with possibly increased efficacy or decreased adverse events.
Key findings
- In addition to the significant cost challenges, the frequent infusions may pose concerns related to access.

How this study scored 45/100
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 and multi-centre collaboration, so those were left out: it earned 26 of the 58 points we could judge it on, which is 45 out of 100.
