This study explores using **tabelecleucel** to treat **Epstein-Barr virus-associated post-transplant lymphoproliferative disease (EBV+ PTLD)**. EBV+ PTLD is a condition where certain white blood cells grow out of control after someone has had a transplant. The study focuses on people who have already tried **rituximab** (a medicine that targets specific cells) and possibly chemotherapy, but these treatments didn't work.
Tabelecleucel is given through an **intravenous (IV)** line, which means it goes directly into the bloodstream. It is administered in cycles of 5 weeks. Participants receive the treatment on Days 1, 8, and 15, and then doctors observe them for the rest of the cycle. The study lasts for a total of 5 years to check on the disease and survival.
- Participants undergo 5-week treatment cycles with IV tabelecleucel.
- The study includes a 5-year follow-up period.
- Participants must have previously tried rituximab treatment.
