Barriers to patient access of CAR T cell therapies in Austria

Abstract

Chimeric antigen receptor (CAR) T cell therapies offer a promising new therapeutic option for treating B cell malignancies, for instance relapsed or refractory diffuse large B cell lymphoma (DLBCL). However, patient access to this type of cellular immunotherapy may be limited due to systemic barriers even in wealthy Western countries. In Austria, the CAR T eligible DLBCL population is estimated to encompass approximately 56 patients based on the criteria applied for CAR T registrational trials. However, less than 40% of these DLBCL patients eligible for commercial standard-of-care CAR T cell therapy were finally treated with CAR T cell therapy in 2021 based on our analysis. This report discusses potential barriers that may impede current patient access to CAR T cell therapy and provides recommendations for systemic solutions to address these barriers and improve the CAR T access situation in Austria.
