To determine the benefit of enzalutamide plus ADT as compared to placebo plus ADT as - assessed by overall survival (OS) - assessed by time to first Symptomatic Skeletal Event (SSE) - assessed by time to castration resistance - assessed by Quality of Life (QoL) (as measured by Quality of Life Prostate-specific Questionnaire [QLQ-PR25] / Functional Assessment of Cancer Therapy-Prostate [FACT-P] and EuroQol Group-5 Dimension-5 Level Instrument [EQ-5D-5L]) - assessed by time to start of new antineoplastic therapy - assessed by time to prostate-specific antigen (PSA) progression - assessed by PSA undetectable rate (< 0.2 ng/mL) - assessed by objective response rate (ORR) - assessed by worsening of pain (as measured by Brief Pain Inventory-Short Form [BPI-SF]) |
Para determinar el beneficio de Enzalutamida además ADT en comparación con placebo más ADT: - Evaluado por la supervivencia global (SG) - Evaluado por el tiempo hasta el primer acontecimiento óseo sintomático (SSE). - Evaluado por el tiempo a la resistencia a la castración - Evaluado por la CdV (conforme al Cuestionario de calidad de vida específico para próstata [QLQ PR25], la FACT P y el Instrumento de 5 dimensiones y 5 niveles del EuroQol Group [EQ 5D 5L]). - Evaluado por el tiempo hasta el inicio del nuevo tratamiento antineoplásico. - Evaluado por el tiempo hasta la progresión según el PSA - Evaluado por la tasa de PSA indetectable (<0,2 ng / mL) - Evaluado por la tasa de respuesta objetiva (TRO) - Evaluado por el empeoramiento del dolor (medido por el Inventario breve del dolor Cuestionario abreviado [BPI SF]). |
