Fosaprepitant for the prevention of nausea and vomiting in patients receiving BEAM or high-dose melphalan before autologous hematopoietic stem cell transplant.

Purpose: To assess the impact of single-dose fosaprepitant on nausea and emesis after BEAM and high-dose melphalan conditioning regimens for autologous hematopoietic stem cell transplantation.
Methods: In a single-center cohort study patients receiving melphalan containing hematopoietic stem cell transplantation regimens who received a one-time dose of 150 mg IV fosaprepitant (n = 56) were compared to a historical control (n = 70).
Results: The primary endpoint of no emesis from melphalan administration through five days afterward was 80% for the fosaprepitant group versus 66% in the control group (p = 0.068). Addition of fosaprepitant demonstrated significant improvement in emetic episodes per patient during the entire assessment period (p = 0.011) and days 1-5 after melphalan (p = 0.045). Fosaprepitant resulted in no substantial nausea during the entire assessment period in 37% of high-dose melphalan patients and 57% of BEAM patients.
Conclusions: Further studies are suggested to investigate the optimal number and timing of doses of fosaprepitant in this setting.
