ABSTRACT
BACKGROUND In the Middle East, there is lack of data on peripheral blood CD34+stem cells mobilization by using biosimilar filgrastim. We have been using both Neupogen and a biosimilar G-CSF) Zarzio® (as a mobilizing agent since February 2014 for both allogenic and autologous stem cell transplantations. MATERIAL AND METHODS This was a single-center retrospective study. All patients and healthy donors who received either the biosimilar G-CSF (Zarzio®) or original G-CSF (Neupogen®) for mobilization of CD34+ stem cells were included in the study. The primary goal was to determine and compare the rate of successful harvest and amount of CD34+ stem cells collected in either adult cancer patients or healthy donors between Zarzio® and Neupogen® groups. RESULTS A total of 114 patients, including 97 cancer patients and 17 healthy donors, underwent successful CD34+ stem cell mobilization using G-CSF with chemotherapy (35 with Zarzio® +chemotherapy, 39 with Neupogen® +chemotherapy) or G-CSF as monotherapy (14 with Zarzio®, 9 with Neupogen®) in autologous transplantation. In an allogeneic stem cell transplantation, successful harvest was achieved by using G-CSF monotherapy (8 with Zarzio®, 9 with Neupogen®). There was no difference between Zarzio® and Neupogen® in the amount of CD34+ stem cells collected at leukapheresis. There was no difference with regards to secondary outcomes between the 2 groups. CONCLUSIONS Our study showed that biosimilar G-CSF (Zarzio®) has comparable efficacy to the original G-CSF (Neupogen®) when used for mobilization in both autologous and allogenic stem cell transplantation and was associated with significant cost saving.
