Amifostine reduces gastro-intestinal toxicity after autologous transplantation for multiple myeloma.

High-dose melphalan (HDM) followed by autologous hematopoietic cell transplantation (auto-HCT) remains the standard-of-care therapy for multiple myeloma (MM) even with the availability of proteasome inhibitors and immunomodulatory drugs. Gastrointestinal (GI) toxicity is the main cause of morbidity after HDM. Amifostine, a cytoprotective agent, may reduce HDM-associated GI toxicity.
