| E.5 End points |
| E.5.1 | Primary end point(s) |
The primary efficacy endpoint is Hb response defined as: - Hb ?11.0 g/dL and a Hb increase from BL Hb by ?1.0 g/dL in any subject with BL Hb>8.0 g/dL, OR - An increase from BL Hb by ?2.0 g/dL in any subject with BL Hb ?8.0 g/dL as measured at 2 consecutive visits separated by at least 5 days during the first 24 weeks of treatment without administration of rescue therapy (i.e., RBC transfusion for all subjects or darbepoetin alfa for FG-4592 treated subjects) prior to Hb response. |
La variable principal de la eficacia es: - La respuesta de la Hb definida como: Hb ? 11,0 g/dl y un aumento de Hb ? 1,0 g/dl respecto a la Hb basal en cualquier sujeto con Hb basal > 8,0 g/dl, O BIEN - un aumento de Hb ? 2,0 g/dl respecto a la Hb basal en cualquier sujeto con Hb basal ? 8,0 g/dl, medida en 2 visitas consecutivas, separadas por al menos 5 días, en las primeras 24 semanas de tratamiento sin administración de tratamiento de rescate (es decir, transfusión de glóbulos rojos para todos los sujetos o darbepoetina alfa para los sujetos tratados con FG-4592) antes de la respuesta de la Hb. |
