Escalation Antifungal Prophylaxis for Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplantation

Feasibility and Outcome of Anti-fungal Prophylaxis With an Escalation Pattern for Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplantation

This is single arm study to evaluate an escalation anti-fungal prophylaxis protocol for patients undergoing allogeneic stem cell transplantation. For all patients without documented proven or probable invasive fungal disease (IFD), patients will receive fluconazole during the treatment in the laminar air flow units (LAF). After discharged from LAF units, patients will receive anti-mold prophylaxis in case of haplo-identical or HLA-matched unrelated donor transplantation to d+100 without active acute GVHD (aGVHD). In case of active aGVHD, the prophylaxis treatment will be extended until recovery of aGVHD and tapering of immunosuppression. In case of HLA-matched sibling donor, fluconazole will be continued to d+100 and anti-mold prophylaxis will be given in case of active aGVHD.

Based on CAESAR study, the IFD incidence increased significantly in patients with unrelated donor or hallo-donor HSCT after patients being discharged from LAF units. The overall incidence of IFD in patients with HLA-matched sibling donor remain low unless in patients with active aGVHD. In this single-arm prospective study, we plan to evaluate the feasibility and effect of an escalation anti-fungal prophylaxis protocol for patients undergoing allogeneic stem cell transplantation. For all patients without documented proven or probable invasive fungal disease (IFD), patients will receive fluconazole during the treatment in the laminar air flow units (LAF). After discharged from LAF units, patients will receive anti-mold prophylaxis in case of haplo-identical or HLA-matched unrelated donor transplantation to d+100 without active acute GVHD (aGVHD). In case of active aGVHD, the prophylaxis treatment will be extended until recovery of aGVHD and tapering of immunosuppression. In case of HLA-matched sibling donor, fluconazole will be continued to d+100 and anti-mold prophylaxis will be given in case of active aGVHD.
