A cytoprotective agent appears to lower GI toxicity and maintain the efficacy of high-dose melphalan (HDM)/autologous hematopoietic cell transplantation (auto-HCT) in patients with multiple myeloma, according to an anlysis involving 221 individuals. Participants had multiple myeloma and were treated at either University Hospitals Cleveland Medical Center with amifostine (740 mg/m2 15 minutes before HDM; n=107) or MD Anderson Cancer Center without the agent. Among the results:
- Amifostine was well tolerated with no significant adverse effects.
- ≥Grade II oral mucositis occurred in 27% of patients pre-treated with amifostine, vs 47% of those who were not treated with the agent.
- Nausea occurred in 32% and 86%, vomiting in 19% and 53%, and diarrhea in 56% and 73%, respectively.
- Amifostine had no visible effect on engraftment, or progression-free or overall survival.
