Abstract
Glofitamab is a novel bispecific antibody targeting CD20×CD3, capable of simultaneously targeting CD20 and CD3 to activate T cells and release cytotoxic proteins that kill cancer cells. Cytokine release syndrome (CRS) is one of the most common adverse events observed in clinical trials of glofitamab. In most cases, CRS is mild, transient, and manageable with appropriate treatment. This paper reports a case of persistent CRS in a patient with mantle cell lymphoma following glofitamab treatment and reviews the relevant literature for reference.
