Overview
Mantle cell lymphoma is a heterogeneous sub-category of non-Hodgkin's lymphoma that can be classified as either an aggressive nodal or an indolent leukemic non-nodal variant. Despite the introduction of Bruton's tyrosine kinase (BTK) inhibitors such as ibrutinib and acalabrutinib, the prognosis for MCL patients remains poor and those that relapse following BTK inhibitor therapy have few treatment options. More recently, chimeric antigen receptor (CAR) T cell therapies have been developed that modify a patient's own T cells using viral transduction to bind to and destroy cancerous cells. These therapies differ in manufacturing methodology, viral vector, chimeric antigen choice, and the internal co-stimulatory domains of the chimeric antigen. Similar to axicabtagene ciloleucel, brexucabtagene autoleucel employs a murine anti-CD19 single-chain variable fragment (scFv) linked to internal CD28- and CD3ζ-derived co-stimulatory domains. However, the preparation of brexucabtagene autoleucel, previously referred to as KTE-X19, uses a method of T cell enrichment that decreases the prevalence of CD19-expressing tumour cells in the CAR T cell preparation. Brexucabtagene autoleucel was granted accelerated approval for the treatment of relapsed and refractory MCL by the FDA on July 24, 2020, and is currently available through Kite Pharma Inc. under the tradename TECARTUS.

Indication
Brexucabtagene autoleucel is a modified autologous chimeric antigen receptor (CAR) T cell immunotherapy indicated for the treatment of relapsed or refractory mantle cell lymphoma (MCL) in adult patients. It is additionally indicated for the treatment of adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). Brexucabtagene autoleucel has been granted accelerated approval based on results from a single-arm, open-label, multicentre clinical trial; continued approval may be contingent on confirmatory trials.
Associated Conditions
