E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectives of this trial are to demonstrate superiority of maintenance therapy with avelumab versus continuation of first-line chemotherapy with regard to Overall Survival (OS) or Progression-free Survival (PFS) as per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) in subjects who have not progressed on firstline chemotherapy. |
El objetivo principal de este ensayo es demostrar la superioridad del tratamiento de mantenimiento con avelumab frente a la continuación de la quimioterapia de primera línea en relación con la supervivencia general (SG) o supervivencia sin progresión (SSP) de acuerdo a los Criterios de Evaluación de la Respuesta en Tumores Sólidos versión 1.1 (RECIST v1.1) en sujetos que no han experimentado progresión con la quimioterapia de primera línea |
|
E.2.2 | Secondary objectives of the trial |
? To demonstrate superiority of maintenance therapy with avelumab versus continuation of first-line chemotherapy with regard to the objective response rate (ORR) as per RECIST v1.1 ? To compare the subject-reported outcomes / quality of life of subjects when treated with avelumab versus continuation of first-line chemotherapy as assessed by the European Quality of Life (EuroQOL) EQ-5D-5L, and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and module QLQ-STO22 ? To determine the safety and tolerability of avelumab |
- Demostrar la superioridad del tratamiento de mantenimiento con avelumab frente a la continuación de la quimioterapia de primera línea en relación con la Tasa de Respuesta Objetiva (TRO) según RECIST v1.1 - Comparar los resultados comunicados por el sujeto/la calidad de vida de los sujetos cuando se han tratado con avelumab frente a la continuación de la quimioterapia de primera línea, mediante el cuestionario Europeo de Calidad de Vida (EuroQoL) EQ-5D-5L y el de la Organización Europea para la Investigación y el Tratamiento del Cáncer (EORTC) QLQ-C30 y el módulo QLQ-STO22. - Determinar la seguridad y la tolerabilidad de avelumab. |
