Expanded Access Protocol for Tabelecleucel for Patients With Epstein-Barr Virus-Associated Viremia or Malignancies
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Read our disclaimer for details.
The primary objective of this protocol is to provide expanded access to tabelecleucel to participants with Epstein-Barr virus-associated diseases and malignancies for whom there are no other appropriate therapeutic options, and who are not eligible to enroll in clinical studies designed to support the development and registration of tabelecleucel.
Participants for whom there are no other appropriate therapeutic options and who are not eligible to enroll in other tabelecleucel clinical studies, may be enrolled in this study. After the screening period, participants will receive intravenous infusions of tabelecleucel (1.6 to 2 × 10^6cells/kg) on Day 1, Day 8, and Day 15 of every 35-day cycle. Clinical assessment of disease response is recommended approximately 15 days after the last dose of tabelecleucel to assess the need for additional treatment. The end of expanded access protocol (EAP) visit should be performed at 30 days after the last dose of tabelecleucel.
Choosing to participate in a study is an important personal decision. Talk with your doctor and family members or friends about deciding to join a study.
