Valganciclovir HCl has been evaluated in numerous clinical trials spanning Phase 1 through Phase 4 across infectious disease and oncology settings. These studies address cytomegalovirus infections, congenital cytomegalovirus, post-transplant complications, Epstein-Barr virus-associated lymphomas, and glioblastoma multiforme, encompassing completed, recruiting, and terminated statuses. Sponsored by academic medical centers, federal institutions, and industry partners, these protocols support applications ranging from post-transplant prophylaxis to targeted therapies for viral lymphoproliferative disorders.
