The purpose of this study is to investigate mobilization and collection of HSPCs in patients with bone marrow failure syndromes (BMFS) using granulocyte-colony stimulating factor (otherwise known as Filgrastim) with plerixafor to demonstrate safety and feasibility of collecting HSPCs to advance gene therapy. Primary objective: \- To characterize the safety of Filgrastim plus plerixafor in participants with bone marrow failure syndromes as determined by the incidence of adverse events (AEs). Secondary Objectives: * To characterize the feasibility of HSPC mobilization using Filgrastim plus plerixafor as determined by peripheral blood CD34+ counts. * To measure the mobilization effects of Filgrastim plus plerixafor in the peripheral blood in participants as determined by peak peripheral blood CD34+ counts. * To estimate efficacy of Filgrastim plus plerixafor for HSPC mobilization and apheresis collection in participants as determined by the yield of CD34+ cells (CD34+ cells/kg).
This is a phase I, open-label, single-center study to evaluate the safety of Filgrastim plus plerixafor stem cell mobilization and apheresis in patients with BMFS. This study will include a screening period with labs, physical examination, and bone marrow evaluation at least 6 months prior to mobilization and apheresis, an intervention period that includes mobilization and apheresis of patient HSPCs, and outpatient follow-up within 7-10 days after intervention. Study staff will follow up with the participant via telephone approximately 30 days after mobilization and apheresis. A bone marrow ev…
Inclusion Criteria: * Participants with a bone marrow failure syndrome with an identified genetic cause willing to donate autologous HSPCs for advancing gene therapy * Age ≥ 18 years - 25 years * The following hematological parameters need to be met (regardless of transfusion or growth factor support) * Hb \> 8 g/dL * ANC \> 500/mm3 * Platelet \> 30,000/mm3 * Bone marrow evaluation within the preceding 6 months prior to mobilization and apheresis * Participants should either have a central venous catheter (CVC) in place, be able to undergo apheresis without requiring a CVC, or agree to…
Administered twice daily dose starting on day 1 for 5 days.
Administered on day 5 via IV.
Peripheral venous access or through a central venous catheter approximately 4-5 hours after the dose of plerixafor is given.
