What the trial is, and whether it could suit you
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 life threatening blood disorders as determined by the incidence of adverse events (AEs).
Secondary Objectives:
* To measure the mobilization effects of Filgrastim plus plerixafor in the peripheral blood in participants as determined by peak peripheral blood CD34+ counts.
* To characterize the feasibility of HSPC mobilization using Filgrastim plus plerixafor as determined by peripheral blood CD34+ counts.
* To estimate efficacy of Filgrastim plus plerixafor for HSPC mobilization and
