It aims to find a safer way to perform stem cell transplants by using donor stem cells that have been specially prepared to remove certain immune cells (called TCRαβ+ T-cells and CD19+ B-cells) using a device called CliniMACS Prodigy System. Participants will also receive a conditioning regimen that includes drugs like Cyclophosphamide and Rabbit Anti-Thymoglobulin (rATG), and some will also receive an experimental antibody treatment called JSP191. The goal is to reduce side effects compared to standard chemotherapy and help the new stem cells engraft (take hold) better. The study will enroll 18 participants and will track serious side effects and successful engraftment for up to two years after the transplant.","Participants will be followed for up to 2 years after the cell infusion.",127,"You would receive a conditioning regimen, a depleted stem cell infusion, and be followed for up to 2 years after the cell infusion.","Not stated in the trial record.",[35,41,51,55],"v2"]
