In 2020, the two EU-projects CARAMBA and EURE-CART jointly organized a regulatory workshop on CAR-T cell development. With the EURE-CART project coming to an end in June 2021, the EURE-CART Consortium has now published a White Paper on CAR-T cell therapy development. Therein, EURE-CART shared their experience on regulatory issues and challenges to harmonize translation from bench to bedside. The experience made is very valuable for future endeavors, especially in CART cell projects. The White Paper is available here at the EURE-CART website.
