E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The overall objectives of the study are to evaluate the long-term safety and durability of GT005 in participants with GA secondary to AMD who have been treated in an antecedent study. The primary endpoint of this study (GT-ORACLE) is to evaluate the long-term safety of GT005 for up to 5 years post-treatment, evaluating the incidence and severity of ocular and systemic adverse events (AEs). |
Los objetivos generales del estudio son evaluar la seguridad y la durabilidad a largo plazo de GT005 en participantes con AG secundaria a DMAE que hayan sido tratados en un estudio anterior. El objetivo principal de este estudio (GT-ORACLE) es evaluar la seguridad a largo plazo de GT005 hasta 5 años después del tratamiento, evaluando la incidencia y la gravedad de los acontecimientos adversos (EA) oculares y sistémicos. |
