Tabelecleucel is under clinical development by Atara Biotherapeutics and currently in Phase II for Non-Hodgkin Lymphoma. According to GlobalData, Phase II drugs for Non-Hodgkin Lymphoma have a 38% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Tabelecleucel’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Tabelecleucel overview

Tabelecleucel (Ebvallo) is an allogeneic Epstein-Barr virus (EBV)-specific T-cell immunotherapy. It is formulated as a dispersion for injection for the intravenous route of administration. Ebvallo is indicated as monotherapy for the treatment of adult and paediatric patients 2 years of age and older with relapsed or refractory Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD) who have received at least one prior therapy. For solid organ transplant patients, prior therapy includes chemotherapy unless chemotherapy is inappropriate.

ATA-129 is under development for the treatment of rituximab-refractory, Epstein-Barr Virus-Associated post-transplant lymphoproliferative disease (PTLD) after solid organ transplantation (SOT) and allogeneic hematopoietic cell transplantation (HCT), hemophagocytic lymphohistiocytosis, hodgkin lymphoma (b-cell hodgkin lymphoma), non-hodgkin lymphoma, solid tumor and lymphoproliferative disorders. Allogeneic EBV specific cytotoxic T- lymphocytes are administered as an intravenous infusion. It is developed based on allogeneic, or off-the-shelf, cytotoxic T-lymphocytes (CTLs) directed against multiple epitopes of the Epstein-Barr virus (EBVpoly) and multiple epitopes of the cytomegalovirus (CMVpoly) utilizing technology.

It was also under development for EBV associated gastric cancer, nasopharyngeal cancer, leiomyosarcoma and lymphomas.
