Clinical Trial Summary

This is a multicenter, open label, single-arm, phase 3 study to assess the efficacy and safety of tabelecleucel for the treatment of Epstein-Barr virus-associated post-transplant lymphoproliferative disease (EBV+ PTLD) in the setting of allogeneic hematopoietic cell transplant (HCT) after failure of rituximab.


Clinical Trial Description

This is a multicenter, open label, single-arm, phase 3 study to assess the efficacy and safety of tabelecleucel for the treatment of EBV+ PTLD in the setting of allogeneic HCT after failure of rituximab. Tabelecleucel will be selected for the subject from the bank of available tabelecleucel cell products based on matching >= 2 human leukocyte antigen (HLA) alleles, at least one of which is a restricting HLA allele, shared between the tabelecleucel donor and the subject's EBV+ PTLD. Sites will provide high resolution subject and subject's graft donor HLA typing results and other information as required by the protocol. Tabelecleucel will be administered in cycles lasting 5 weeks (35 days). During each cycle, subjects will receive intravenous (IV) tabelecleucel at a dose of 2×10^6 cells/kg on Days 1, 8, and 15, followed by observation through Day 35. NOTE, 29 April 2020: Study sites/locations with status "completed" may be screening EBV+ PTLD HCT subjects in clinical study ATA129-EBV-302 (NCT03394365). NOTE, 16 February 2021: all study sites have closed and all data has been transferred to the clinical study database for monitoring under ATA129-EBV-302 (NCT03394365). ;
