Filgotinib

Le filgotinib est une molécule inhibitrice spécifique de la janus kinase 1 et en cours de test comme médicament.

Mode d'action modifier

Il a une affinité trente fois supérieure pour la janus kinase 1 par rapport à celle pour la janus kinase 2^[1]

Pharmacocinétique modifier

Après absorption orale, il se transforme en un métabolite actif dont la demi-vie est d'un peu moins de 24 h^[2].

Efficacité modifier

Dans la polyarthrite rhumatoïde et en association avec le méthotrexate, il permet une amélioration des symptômes de la maladie^[3]. Dans les formes résistantes de la maladie, il conserve une activité^[4].

Il a des résultats prometteurs dans la maladie de Crohn^[5] et dans la rectocolite hémorragique^[6].
