E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of ION-682884 after administration for 65 weeks, as compared to the historical control of the placebo cohort (inotersen) in the NEURO-TTR trial, based on the change from Baseline in serum TTR concentration, mNIS+7 and in the Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QOL-DN) in patients with hATTR. |
Evaluar la eficacia de ION-698884 tras administración durante 65 semanas, en comaración con el control histórico de la cohorte del placebo (inotersen), basándose en el cambio desde el inicio en la concentración sérica de TTR, mNIS+7 y el cuestionario sobre la calidad de vida con neuropatía diabética de Norfolk (Norfolk QOL-DN) en pacientes con PAF-TTR |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of ION-682884, as compared to the placebo cohort in the NEURO-TTR trial, based on the change from Baseline in the following measures: - Neuropathy Symptom and Change Score (NSC) - Physical component summary (PCS) score of 36-Item Short Form Survey (SF-36) - Polyneuropathy disability (PND) score - Modified body mass index (mBMI) |
Evaluar la eficacia de ION-682884, en comparación con la cohorte de placebo del ensayo NEURO-TTR, basándose en el cambio desde el inicio en lo siguiente: •Puntuación en el cuestionario de síntomas y cambios de la neuropatía (NSC) •Puntuación en el resumen del componente físico (PCS) del cuestionario breve de salud de 36 ítems (SF-36) •Puntuación de discapacidad por polineuropatía (PND) •Índice de masa corporal modificado (IMCm) |
