# Case Report: Glofitamab in the treatment of a patient with central nervous system-involved Burkitt lymphoma

## TL;DR

A patient with central nervous system Burkitt lymphoma showed a favorable response to glofitamab combined with a BTK inhibitor, achieving long-term remission.

## Contribution

This case report demonstrates the potential efficacy of glofitamab in treating CNS-involved Burkitt lymphoma.

## Key findings

- The patient achieved significant improvement in CNS infiltration after six cycles of glofitamab and a BTK inhibitor.
- The treatment resulted in a long remission period for the patient with relapsed/refractory Burkitt lymphoma.
- This case suggests that glofitamab may be a promising therapy for CNS lymphoma.

## Abstract

Burkitt lymphoma (BL) is a rare and highly aggressive B-cell non-Hodgkin lymphoma. While targeted combination chemotherapy can be effective, it is associated with a high rate of relapsed or refractory disease and a pronounced propensity for central nervous system (CNS) involvement. Currently, novel therapies such as chimeric antigen receptor T-cell (CAR-T) therapy have not demonstrated established efficacy in BL. Given the poor prognosis and the challenge of managing relapsed/refractory BL, the use of bispecific antibodies, specifically glofitamab, as employed in this case, has yielded a favorable therapeutic outcome. This is particularly noteworthy in the present case, given the patient’s documented CNS infiltration. After the failure of first-line treatment in this case, the combination of glofitamab and a Bruton’s tyrosine kinase inhibitor (BTKi) was used for six cycles, which significantly improved the patient’s CNS infiltration and achieved a long remission period. This provides an opportunity to try glofitamab in the treatment of CNS lymphoma, and we look forward to its confirmation in more BL patients.
