CAR-T cell therapy in hematological malignancies: Where are we now and where are we heading for?

Chimeric antigen receptor T (CAR-T) therapy has emerged as a revolutionary new pillar in cancer care, particularly in relapsed/refractory (r/r) B-cell malignancies. Following impressive clinical outcomes in hematological malignancies, the FDA-approved six CAR-T cell products for indications such as lymphoma, leukemia, and myeloma. Despite the numerous advantages of CAR-T cell treatment, several challenges exist that interfere with its therapeutic efficacy.

Immunogenicity of CAR-T Cell Therapeutics: Evidence, Mechanism and Mitigation.

Chimeric antigen receptor T cell (CAR-T) therapy demonstrated remarkable success in long-term remission of cancers and other autoimmune diseases. Currently, six products (Kymriah, Yescarta, Tecartus, Breyanzi, Abecma, and Carvykti) are approved by the US-FDA for treatment of a few hematological malignancies. All the six products are autologous CAR-T cell therapies, where delivery of CAR, which comprises of scFv (single-chain variable fragment) derived from monoclonal antibodies for tumor target antigen recognition is through a lentiviral vector.
