Summary

Patients receiving an allogeneic hematopoietic stem cell transplant (allo-CSH) are at high risk of infection, particularly of fungal origin. Until the 2018 recommendations of the 6th European Conference on Infections in Leukemia (ECIL6), primary prophylaxis of invasive fungal infections (IFI), in allograft patients, was based on the administration of fluconazole until D100. Due to changes in transplantation practices (alternative donor transplantation, sequential transplantation, etc.) and changes in microbiological ecology (increased incidence of IFIs caused by filamentous germs such as aspergillosis and mycormycosis), fluconazole prophylaxis is now sometimes suboptimal. It is therefore recommended that patients at high risk of developing IFIs should be given azole molecules with activity against filamentous agents as primary prophylaxis during the first 3 months after transplantation.

Posaconazole is often under-dosed (below the minimum effective concentration). It therefore seems essential to carry out a prospective study with close \[C\]min dosing in the specific situation of allograft patients, a population that appears to be at risk of underdosing in the light of initial retrospective analysis results.

Conditions

  • Hematologic Malignancy

Interventions

DRUG

Posaconazole

Per Os, on Day 0 of allo-CSH if the patient's condition permits, or after the last dose of immunosuppressor (post-transplant cyclophosphamide) (Day+5 or Day+6 depending on protocols). On the first day of treatment: 300 mg in the morning (= 3 x 100 mg tablets) and 300 mg in the evening (= 3 x 100 mg tablets), then from day 2 of treatment: 300 mg per day (= 3 x 100 mg tablets) in a single dose
