Study summary

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.

Read the detailed description

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Any of the following diagnoses of EBV+ or disease:

    1. EBV+ PTLD following hematopoietic cell transplant (HCT)
    2. EBV+ PTLD following solid organ transplant (SOT)
    3. Persistent EBV viremia and known or suspected immunodeficiency
    4. EBV+ LPD that has developed in the setting of an AID
    5. EBV+ LPD that has developed in the setting of a known or suspected PID
    6. EBV+ LMS
    7. EBV+ NPC
  2. The evidence of EBV positivity
  3. disease, defined as failure to achieve response (ie, complete response or partial response) or recurrent disease following therapy, ie, systemic therapy for EBV-related malignancy or viremia for which there are no appropriate therapies.
  4. Not eligible for any other Atara clinical development study
  5. For participants developing PTLD following allogeneic HCT for acute leukemia, the underlying acute leukemia must be in morphologic remission
  6. Adequate organ function per the following:

    1. >= 500/μL, with or without cytokine support
    2. count >= 20,000/μL, with or without transfusion support
  7. Participant or participant's representative is willing and able to provide written

Exclusion criteria

Exclusion Criteria:

  1. Current diagnosis of Burkitt's lymphoma, classical Hodgkin's lymphoma, or any T-cell lymphoma
  2. Prior treatment with any product within 4 weeks of first treatment with tabelecleucel, or within 5 half-lives from the most recent dose to first treatment with tabelecleucel
  3. Ongoing need for methotrexate or extracorporeal photopheresis; doses > 1 mg/kg/day of prednisone (or equivalent)
  4. Need for vasopressor or ventilatory support, unless deemed to be caused by the EBV-driven process that tabelecleucel is intended to treat
  5. Antithymocyte globulin, alemtuzumab, or similar anti-T-cell antibody therapy, or T-cell immunotherapy (donor lymphocyte infusion, other cytotoxic T lymphocytes [CTLs]) \<= 4 weeks prior to first treatment with tabelecleucel
  6. Pregnancy
  7. Female of or male with a female partner of childbearing potential, either of whom are unwilling to use a highly effective method of
Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
