BNT211 is a potential first-in-class therapeutic for third- or later-line treatment of testicular germ cell tumors. It is a combination of a CAR-T cell therapy targeting the oncofetal antigen Claudin-6 (CLDN6) and a CLDN6-encoding CAR-T cell amplifying RNA vaccine (CARVac).
The candidate is currently in a phase 1/2a trial.
Preliminary data from the trial indicated early signs of anti-tumor activity as well as a positive safety profile.
