Lenograstim reduces the incidence of febrile episodes, when compared with filgrastim, in multiple myeloma patients undergoing stem cell mobilization

Abstract

The aim of this study was to show a lower incidence of febrile episodes in multiple myeloma patients receiving lenograstim vs. filgrastim after high-dose cyclophosphamide for stem cell mobilization. Patients treated with cyclophosphamide were randomly assigned to receive filgrastim or lenograstim. Primary endpoint was the incidence of febrile episodes. 5.1% patients developed a febrile episode, 9.1% with filgrastim and 1.1% with lenograstim. Lenograstim group presented a significantly higher absolute CD34+ cell number compared with the filgrastim group but no differences were detected for collection efficacy. The study demonstrated a lower incidence of febrile episodes with lenograstim compared to filgrastim.
