Topic: Amyloid, tau and blood-test diagnosis

La hipótesis amiloide, que propone la acumulación del péptido ?-amiloide (?A) en la sinapsis, es el factor clave de la patogénesis de la enfermedad de Alzheimer (EA) y esta ha sido la idea dominante en el campo de la investigación de la EA durante casi 30 años. Numerosos fármacos anti-?A que inhiben la producción o la agregación de ?A o estimulan su eliminación, no han demostrado un beneficio clínico en ensayos sobre la EA a gran escala; por su parte, aducanumab, un anticuerpo monoclonal para el tratamiento de la EA temprana, ha mostrado su capacidad para reducir sustancialmente la carga de placa cerebral. Además, otros dos potentes anticuerpos monoclonales, como lecanemab y donanemab, han mostrado su capacidad de eliminar, de forma rápida y sustancial, las placas cerebrales y han producido recientemente resultados cognitivos y clínicos alentadores en personas con EA temprana. Específicamente, lecanemab es un anticuerpo que se une a grandes agregados de ?A solubles (protofibrillas) y en el ensayo clínico de fase III en personas con EA temprana (CLARITY AD; NCT03887455), lecanemab ralentizó un 27?% el deterioro cognitivo después de administrarlo durante 18 meses. En el estudio se inscribieron 1795 participantes, de los cuales 898 fueron asignados para recibir lecanemab y 897 para placebo. En la escala de valoración de la clínica de la demencia: suma de casillas (CDR-SB, según sus siglas en inglés), tuvo una puntuación media al inicio de la valoración, aproximadamente de 3,2 en ambos grupos. El cambio medio se reportó y fue ajustado por mínimos cuadrados desde el inicio a los 18 meses, resultando un descenso a 1,21 con lecanemab y de 1,66 con placebo. Además, 698 participantes de un subestudio presentaron mayores reducciones de la carga ?A con lecanemab que con placebo (diferencia -59,1 centiloides). El estudio demostró que lecanemab aminoró de forma importante el acúmulo de ?A en el cerebro y también fue mejor que el placebo en los objetivos secundarios estudiados (escalas cognitivas y biomarcadores biológicos).

Key findings

Why it matters

This review describes lecanemab as an antibody that binds soluble amyloid-beta aggregates and, in the phase III CLARITY AD trial of 1795 participants, slowed cognitive decline by 27 percent over 18 months. It summarizes existing trial evidence rather than presenting new findings on curing or preventing the disease.

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 senior author's track record, so that was left out: it earned 29 of the 96 points we could judge it on, which is 30 out of 100.
