Study Overview
Brief Summary
Fanconi anemia (FA) is a congenital disease characterized by bone marrow failure and increased incidence of malignant tumors. The Project pursue the optimization of the collection of hematopoietic progenitor cells for later use in another clinical trial entitled "Clinical Trial Phase I/II to evaluate the safety and efficacy of the infusion of autologous CD34+ cells mobilized with mozobil and filgrastim, and transduced with a lentiviral vector carrying the FANCA gene (Orphan Drug) for patients with Fanconi Anemia Subtype A ". The objectives of this study are, therefore, to assess the safety and efficacy of CD34+ cells mobilization with mozobil and filgrastim, which is postulated the most efficient for the collection of CD34+ cells from FA patients.

Outcomes
Primary Outcomes
Toxicity of the mobilization procedure according to National Cancer Institute (CTC NCI, versión 3.0)
Time Frame: after 12 months
At a year (± 30 days) after the last apheresis, a complete physical examination, blood cell count, basic biochemistry and bone marrow aspirate will be done to the patient in order to control their general health status.
Secondary Outcomes
- Percentage of patients that reach >5 CD34+ cells/mcl after treatment with filgrastim and plerixafor(after 8 days)
- Percentage of patients that reach a total CD34+ yield >4x10E6/kg, using the estimated weight of the patient in 5 years(after 8 days)
- Percentage of samples in which the recovery of CD34+ cells after the immunomagnetic selection procedure is >50%(after 8 days)
- Percentage of patients in which the CD34+ cells after the immunomagnetic selection is ³ 4x10E6/kg, using the projected weight at 5 years(after 8 days)
