Tabelecleucel for Solid Organ or Allogeneic Hematopoietic Cell Transplant Participants With Epstein-Barr Virus-Associated Post-Transplant Lymphoproliferative Disease (EBV+ PTLD) After Failure of Rituximab or Rituximab and Chemotherapy


Brief description of study

The purpose of this study is to determine the clinical benefit and characterize the safety profile of tabelecleucel for the treatment of Epstein-Barr virus-associated post-transplant lymphoproliferative disease (EBV+ PTLD) in the setting of (1) solid organ transplant (SOT) after failure of rituximab and rituximab plus chemotherapy or (2) allogeneic hematopoietic cell transplant (HCT) after failure of rituximab.

Detailed Study Description

This is a multicenter, open-label, phase 3 study to assess the efficacy and safety of tabelecleucel for the treatment of EBV+ PTLD in the setting of SOT after failure of rituximab and rituximab plus chemotherapy (SOT cohort) or HCT after failure of rituximab (HCT cohort).

Enrollment will be preceded by confirmation of availability of partially human leukocyte antigen (HLA) matched and restricted tabelecleucel for the participant.

Study procedures and product administration will be the same for each cohort. Tabelecleucel will be administered in cycles lasting 5 weeks (35 days). During each cycle, participants will receive intravenous tabelecleucel at a dose of 210^6 cells/kg on Days 1, 8, and 15, followed by observation through Day 35. Treatment will continue until maximal response, unacceptable toxicity, initiation of non protocol therapy, or failure of tabelecleucel with up to 2 different HLA restrictions (SOT cohort) or up to 4 different HLA restrictions (HCT cohort).

This protocol has been amended to include the HCT cohort from clinical study ATA129-EBV-301 (NCT03392142).
