Mexican Biosimilar Filgrastim for Autologous Hematopoietic Stem Cell Mobilization and Transplantation

Following the release of the initial presentation of filgrastim (granulocyte colony-stimulating factor), several biosimilars have been developed worldwide. To study the efficacy of a Mexican biosimilar granulocyte colony-stimulating factor in a single transplant center. In a group of 19 consecutive patients with multiple sclerosis given autografts, we employed granulocyte colony-stimulating factors to mobilize stem cells from the bone marrow to the peripheral blood, either the original granulocyte colony-stimulating factor (n = 10) or a Mexican granulocyte colony-stimulating factor biosimilar (n = 9). The efficacy of both agents was similar in mobilization capacity, white blood cell count rise, stem cell collection, and kinetics of auto-engraftment. We conclude that both granulocyte colony-stimulating factor agents were similar in their efficacy to mobilize stem cells and usefulness in autografts.
