The main questions it aims to answer are:\n\n* Does LB-DTK-BKV reduce the number of BKV virus viral load in allo-HSCT patients with hemorrhagic cystitis?\n* Do adverse events occur after the second dose? Researchers will compare LB-DTK-BKV to a placebo to see if LB-DTK-BKV works to treat hemorrhagic cystitis in allo-HSCT patients.\n\nParticipants will:\n\n* Receive a single intravenous infusion of LB-DTK-BKV at the baseline visit (low dose: 1x10\\^7\u002Fm\\^2; high dose: 2x10\\^7\u002Fm\\^2).\n* Receive the second dose of LB-DTK-BKV intravenously at the same dose 14 days after the first dose.\n* Visit the clinic every week for follow-up for 6 months after the first dose.",[173],"Hemorrhagic Cystitis",[175,173,176,177,178,179,180,181],"BK-Virus","Virus-specific T cells","Allogeneic Hematopoietic Stem Cell Transplantation","Stem Cell Transplant","Virus Diseases","Infections","Cystitis","NOT_YET_RECRUITING","2026-06-15",{"date":185,"type":186},"2026-06-17","ACTUAL",{"date":188,"type":166},"2026-09-01",{"date":190,"type":166},"2028-03-01",{"name":5,"class":6},9]
