Semorinemab

Summary

El semorinemab (denominación común internacional (INN), nombre adoptado en Estados Unidos (USAN); nombres en desarrollo MTAU-9937A, RG-6100, RO-7105705) es un anticuerpo monoclonal dirigido contra la proteína tau, que estuvo en desarrollo para el tratamiento de la enfermedad de Alzheimer, pero que fue discontinuado.[2][3][4]​ Se une al extremo N-terminal de las seis isoformas de tau.[3][4]​ El fármaco resultó ineficaz en el tratamiento del Alzheimer en dos ensayos clínicos de fase 2.[3][4]​ El desarrollo clínico de semorinemab para la enfermedad de Alzheimer se interrumpió en febrero de 2024.[2]

However, these antibodies achieved negative outcomes in AD and primary tauopathy clinical trials, showing lack of efcacy and missing their primary endpoints. An exception is semorinemab which, in one of the two phase 2 trials, improved cognitive function (one of the co-primary endpoints) without afecting the activities of daily living or any of the prespecifed secondary outcomes [62]. Tese negative outcomes were achieved despite clear evidence of target engagement, with N-terminal tau decreasing in CSF and increasing in plasma. In the most extreme example, gosuranemab decreased N-terminal tau in CSF by 98% (11% increase for placebo) without showing clinical efcacy in progressive supranuclear palsy (PSP).»
