简要总结
The purpose of this protocol is to provide access to the CliniMACS® System to hematopoietic cell transplant (HSCT) patients who do not have a matched related donor. The CliniMACS system is currently approved for use in patients who have AML, and a genetically matched sibling donor. Through this protocol, the investigators will be able to offer potentially life-saving transplants to patients who have genetically mis-matched donor, who have no other options for treatment.

入选标准
- •Participant age is 0 (newborn) to 35 years-old.
- •Participant has a disorder affecting the hematopoietic system that are inherited, acquired, or a result from the myeloablative treatment that can benefit from alternative stem cell transplantation according to standard practice guidelines for including patients for transplant.
- •Participant's medical screening clears s/he for allogeneic transplantation as per current institutional SOP based on standards of foundation for accreditation of cellular therapy and stem cell transplantation (FACT);
- •Participant must lack a healthy, HLA-identical related or unrelated donor unless s/he has a borderline organ function that will preclude the recipient from receiving a curative therapy due to the need of post-HSCT immunosuppressive therapy.
- •Participant must have a matched or mismatched-related donor who is:
- •Able to receive granulocyte colony-stimulating factor (G-CSF) and undergo apheresis either through placement of catheters in antecubital veins or a temporary central venous catheter OR agrees on a bone marrow harvest;
- •Healthy as per donor selection screening (following current SOP based on standards of foundation for accreditation of cellular therapy and stem cell transplantation - FACT);
- •Willing to participate and sign consent.
- •Participant or Legal Authorized Representative is able to sign informed consent (and signed assent, if applicable) for transplant.
排除标准
- •Participant does not qualify for an allogeneic transplant due to medical screening, underlying disease, or lack of alternative donors.
- •Any condition that compromises compliance with the procedures of this protocol, as judged by the principal investigator.
