E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the effects of bosentan (endothelin inhibitor), in combination with conventional therapy, in patients with a sudden decrease in visual acuity, either uni or bilaterally, in the acute phase of giant cell arteritis (Horton's disease) , on recovery of visual acuity at 3 months. |
Evaluer les effets du bosentan (inhibiteur de l’endothéline), en adjonction du traitement conventionnel, chez des patients présentant une baisse brutale d’acuité visuelle uni ou bilatérale, à la phase aigüe de l’artérite à cellule géante (maladie de Horton), sur la récupération d’acuité visuelle à 3 mois. |
