Brentuximab vedotin desensitization in a patient with refractory Hodgkin's lymphoma

Brentuximab vedotin has emerged as a useful treatment option for relapsed or refractory Hodgkin's lymphoma; however, uncommon cases of anaphylactic reactions may require its permanent discontinuation. We report a 29‐yr‐old woman with refractory Hodgkin's lymphoma, who developed an anaphylactic reaction during the second dose of brentuximab vedotin. A 12‐step desensitization protocol was followed; after premedicating with antihistaminic agents, methylprednisolone and montelukast, a total dose of 156 mg of brentuximab vedotin (1.8 mg/kg) was given as three infusions with increasing rate and concentration. Such desensitization protocol can allow safe administration of brentuximab vedotin and may have a broader applicability in managing hypersensitivity reactions with other monoclonal antibodies.
