Summary
This trial will test the safety and effectiveness of a new treatment for a type of cancer that can occur after organ transplantation.
Who is the study for?
This trial is for people who've had a solid organ or stem cell transplant and now have a condition called EBV+ PTLD, which hasn't improved after treatment with Rituximab alone or with chemotherapy. Participants must be in stable condition without the need for intensive support like ventilators, not have certain other diseases or ongoing severe infections, and women of childbearing age must agree to use effective contraception.
What is being tested?
The study is testing tabelecleucel's effectiveness and safety in treating EBV+ PTLD among those who've undergone either solid organ transplants (like kidney, liver) or allogeneic hematopoietic cell transplants (stem cells from donors). The participants should have previously tried treatments that didn't work well enough.
What are the potential side effects?
While specific side effects of tabelecleucel are not listed here, similar therapies can cause immune reactions, fatigue, fever, digestive issues and may affect blood counts. Organ function might also be impacted. Side effects vary by individual.
