Many drugs are used for unapproved indications in Japan for post hematopoietic stem cell transplant (HCT) complications. To investigate unapproved or off-label drug usage for graft-versus-host disease (GVHD) and virus infections after allogeneic HCT, we analyzed the data of Japanese HCT registry. Between 2006 and 2017, 39,941 adults and children received HCT for a variety of disease and their transplant data were captured in the registry. Among them, 14,687 and 8914 patients receiving treatment for acute and/or chronic GVHD, 24,828 patients with cytomegalovirus (CMV) infection or receiving therapies for CMV, and 4943 who received treatment for other viral infections were included in the analyses of off-label or unapproved drugs. For GVHD, mycophenolate mofetil was the most frequently used off-label drug, followed by beclomethasone, infliximab, and etanercept. For viral infections other than CMV, foscarnet was the most frequently used off-label drug. Cidofovir, which is not approved for use in Japan, was mainly used for adenovirus infection. This study demonstrated that numerous off-label and unapproved drugs have been used as key drugs for GVHD and post-transplant viral infection, and the real world date in the transplant registry may serve as an important asset to regulatory purposes.
