The final analysis for the ITT population will occur after 449 deaths have been observed (expected 29 months after first patient in [FPI]), while the final analysis for the Met 2+/3+ subgroup will occur after118 deaths in the Met 2+/3+ subgroup have been observed (expected 38 months after FPI). Follow-up for survival will continue until all patients have either died, or are lost to follow-up, or the Sponsor decides to end the trial, whichever occurs first. |
El análisis final (AF) de la población IT se realizará cuando se observen 449 muertes (previsto 29 meses después de la entrada del 1er paciente [EPP]), mientras que el AF para el subgrupo de Met 2+/3+ tendrá lugar cuando se observen 118 muertes en el subgrupo de Met 2+/3+ (previsto 38 meses después de la EPP).
