PHASE3

Brief Summary

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 lymphoproliferati...

Detailed 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-R and SOT-R+C (Cohort \[C\]-SOT) or HCT after f...

Eligibility Criteria

Inclusion

  • Prior SOT of kidney, liver, heart, lung, pancreas, small bowel, or any combination of these (C-SOT); or prior allogeneic HCT (C-HCT).
  • A diagnosis of locally assessed, biopsy-proven EBV+ PTLD.
  • Availability of appropriate partially HLA-matched and restricted tabelecleucel has been confirmed by the sponsor.
  • Measurable, 18F-deoxyglucose (FDG)-avid (Deauville score ≥ 3) systemic disease using Lugano Classification response criteria by positron emission tomography (PET)-diagnostic computed tomography (CT), except when contraindicated or mandated by local practice, then magnetic resonance imaging (MRI) may be used. For participants with treated central nervous system (CNS) disease, a head CT and/or brain/spinal MRI as clinically appropriate will be required to follow CNS disease response per Lugano Classification response criteria.
  • Treatment failure of rituximab or interchangeable commercially available biosimilar monotherapy (C-SOT-R or C-HCT) or rituximab plus any concurrent or sequentially administered chemotherapy regimen (C-SOT-R+C) for treatment of PTLD.
  • Males and females of any age.
  • Eastern Cooperative Oncology Group performance status ≤ 3 for participants aged ≥ 16 years; Lansky score ≥ 20 for participants \< 16 years.
  • For C-HCT only: If allogeneic HCT was performed as treatment for an acute lymphoid or myeloid malignancy, the underlying primary disease for which the participant underwent transplant must be in morphologic remission.
  • Adequate organ function.
  • Absolute neutrophil count ≥ 1000/μL, (C-SOT) or ≥ 500/μL (C-HCT), with or without cytokine support.
  • Platelet count ≥ 50,000/μL, with or without transfusion or cytokine support. For C-HCT, platelet count \< 50,000/μL but ≥ 20,000/μL, with or without transfusion support, is permissible if the participant has not had grade ≥ 2 bleeding in the prior 4 weeks (where grading of the bleeding is determined per the National Cancer Institute's Common Terminology Criteria for Adverse Events \[CTCAE\], version 5.0).
  • Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin each \< 5 × the upper limit of normal; however, ALT, AST, and total bilirubin each ≤ 10 × upper limit of normal is acceptable if the elevation is considered by the investigator to be due to EBV and/or PTLD involvement of the liver as long as there is no known evidence of significant liver dysfunction.
  • Participant or participant's representative is willing and able to provide written informed consent.

Exclusion

  • Currently active Burkitt, T-cell, NK/T-cell lymphoma/LPD, Hodgkin, plasmablastic, transformed lymphoma, active hemophagocytic lymphohistiocytosis, or other malignancies requiring systemic therapy.
  • Daily steroids of \> 0.5 mg/kg prednisone or glucocorticoid equivalent, ongoing methotrexate, or extracorporeal photopheresis.
  • Untreated CNS PTLD or CNS PTLD for which the participant is actively receiving CNS-directed chemotherapy (systemic or intrathecal) or radiotherapy at enrollment. NOTE: Participants with previously treated CNS PTLD may enroll if CNS-directed therapy is complete.
  • Suspected or confirmed grade ≥ 2 graft-versus-host disease (GvHD) per the Center for International Blood and Marrow Transplant Research consensus grading system at enrollment.
  • Ongoing or recent use of a checkpoint inhibitor agent (eg, ipilimumab, pembrolizumab, nivolumab) within 3 drug half-lives from the most recent dose to enrollment.
  • For C-HCT: active adenovirus viremia.
  • Need for vasopressor or ventilatory support.
  • Antithymocyte globulin or similar anti-T cell antibody therapy ≤ 4 weeks prior to enrollment.
  • Treatment with Epstein-Barr virus cytotoxic T lymphocytes or chimeric antigen receptor T cells directed against B cells within 8 weeks of enrollment (C-SOT or C-HCT), or unselected donor lymphocyte infusion within 8 weeks of enrollment (C-HCT only).
  • Female who is breastfeeding or pregnant or female of childbearing potential or male with a female partner of childbearing potential unwilling to use a highly effective method of contraception.
  • Inability to comply with study-related procedures.
  • Any medical condition or organ system dysfunction that in the investigator';s opinion, could compromise the participant's safety or ability to complete the study.
