What is AUTO4?

AUTO4 is an autologous T-lymphocyte cell therapy engineered to express a chimeric antigen receptor with an anti-TRBC1 single chain variable fragment, the 4-1BB co-stimulatory domain and the CD3-zeta signaling chain. It binds TRBC1 on tumor cell surfaces, leading to lysis of TRBC1-expressing cells, and carries the RQR8 off switch that allows selective removal of the T cells with rituximab. It is studied in T-cell non-Hodgkin lymphomas, including peripheral T-cell lymphoma, angioimmunoblastic T-cell lymphoma and anaplastic large cell lymphoma.
