Background: Hypersensitivity reactions (HSRs) to chemotherapeutic drugs, including mAbs, often require that the provoking medication be discontinued, thus raising a dilemma for the caregiver: further use could precipitate a severe, even fatal, allergic reaction on re-exposure, but alternative drugs might be poorly tolerated or much less effective compared with the preferred agent.
Objective: We have developed a standardized rapid desensitization protocol for achieving temporary tolerization to drug allergens. In this study we evaluate the safety and efficacy of this protocol.
