Stem Cell Mobilization and Apheresis for Life-threatening Blood Disorders
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).

Experimenteel: BDSTEM Treatment
Participants in this study will receive a twice daily dose of Filgrastim (GCSF) (5 mcg/kg BID) SQ starting on day 1 for 5 days followed by a single dose of SQ plerixafor (0.24 mg/kg) on day 5 followed by collection of CD34+ HSPCs via apheresis. A portion of cells collected from the participant will be stored as backup to be used toward future gene therapy endeavors. The remaining cells will be donated for research studies |
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.
