- Medical intolerance to anti-viral therapies including:

2 Donor Eligibility 5.2.1 Related donor available with a T-cell response to the EBV MACS®
GMP PepTivator antigen(s) causing the therapy-refractory EBV infection.
a. Third Party Related Allogeneic Donor: If original donor is not available or does not
have a T-cell response: third party related allogeneic donor (family donor > 1 HLA A, B, DR

MACS® GMP PepTivator EBV Select (containing among other antigens, NA-1, LMP2A and BZLF-1).
AND Allogeneic donor disease screening is complete similar to hematopoietic stem cell
donors (Appendix 1).
AND Obtained informed consents by donor or donor legally authorized representative prior to
donor collection.
