E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Determine that intralesional administration of Adalimumab associated to endoscopic dilatation has a higher success rate at week 8 compared with placebo |
Determinar que la inyección intralesional de Adalimumab asociado a la dilatación endoscópica consigue una mayor proporción de éxito a la semana 8 comparado con dilatación + placebo |
|
E.2.2 | Secondary objectives of the trial |
-To demonstrate that the intralesional injection of Adalimumab associated with endoscopic dilatation will decrease the necessity of endoscopic redilatation or surgery at week 52 -To evaluate the mucosal cure rate associated with the stenosis resolution at week 8 and week 52 after endoscopic dilatation, defined, in case of postsurgical stenosis, as Rutgeert´s index equal or less than 2 -To evaluate the complication incidence associated with every one of realized procedures as well as the adverse events in every group of treatment -To analyze the rate of formation of anti-adalimumab antibodies during the follow up after unique local injection of the drug -To determinate the histological cure rate at week 8 after the injection of the drug or placebo |
-Demostrar que la inyección intralesional de Adalimumab asociada a la dilatación endoscópica consigue reducir la necesidad de redilatación endoscópica o cirugía a la semana 52 -Valorar la tasa de curación mucosa asociada a la resolución de la estenosis a la semana 8 y la semana 52 después de la dilatación endoscópica, definida, en el caso de estenosis postquirúrgica, como un Índice de Rutgeerts menor o igual que 2 -Evaluar la tasa de complicaciones asociadas a cada uno de los procedimientos realizados así como de acontecimientos adversos en cada uno de los grupos de tratamiento -Analizar la tasa de anticuerpos anti-adalimumab desarrollados en el seguimiento tras una única inyección local del fármaco -Determinar la tasa de curación histológica a las 8 semanas de la inyección del fármaco o placebo |
