Title
(EN) DENDRITIC POLYMERS COMPLEXED WITH IMMUNE CHECKPOINT INHIBITORS FOR ENHANCED CANCER IMMUNOTHERAPY
(FR) POLYMÈRES DENDRITIQUES COMPLEXÉS AVEC DES INHIBITEURS DE POINT DE CONTRÔLE IMMUNITAIRE POUR AMÉLIORER L'IMMUNOTHÉRAPIE ANTICANCÉREUSE
Abstract
(EN)
Described herein is a nanoparticle system including a multivalent nanoparticle core having a plurality of immune checkpoint inhibitors conjugated thereto. Also included are pharmaceutical compositions and methods of making the nanoparticle system. Further included are immunotherapy methods including administering the nanoparticle system to a subject in need thereof, such as a human cancer patient.
(FR)
L'invention concerne un système de nanoparticules qui comprend un noyau de nanoparticule multivalent auquel sont conjugués de nombreux inhibiteurs de points de contrôle immunitaire. L'invention concerne également des compositions pharmaceutiques ainsi que des procédés de fabrication du système de nanoparticules. L'invention concerne en outre des méthodes d'immunothérapie comprenant l'administration du système de nanoparticules à un patient qui en a besoin, tel qu'un patient humain atteint de cancer.
