Axicabtagene ciloleucel (Yescarta)

Mechanism of action

From the NCI Drug Dictionary: A preparation of autologous peripheral blood T-lymphocytes (PBTL) that have been transduced with a gammaretroviral vector expressing a chimeric antigen receptor (CAR) consisting of an anti-CD19 single chain variable fragment (scFv) coupled to the costimulatory signaling domain CD28 and the zeta chain of the T-cell receptor (TCR)/CD3 complex (CD3 zeta), with potential immunostimulating and antineoplastic activities. Upon intravenous infusion and re-introduction of axicabtagene ciloleucel into the patient, these cells bind to and induce selective toxicity in CD19-expressing tumor cells.
