Medical intolerance to anti-viral therapies including:
Performance Status > 30% (Lansky \< 16 yrs and > 16 yrs) Age: 0.1 to 79 years
Females of with a negative urine pregnancy test
Donor Eligibility Related donor available with a T-cell response to the viral MACS® GMP PepTivator antigen(s) of adenovirus.
a. Third Party Related Allogeneic Donor: If original donor is not available or does not have a T-cell response: third party allogeneic donor (family donor > 1 HLA A, B, DR match to recipient) with a T-cell response at least to the viral MACS® GMP PepTivator antigen(s) of adenovirus.
AND Allogeneic donor disease screening is complete similar to hematopoietic stem cell donors (Appendix 1).
AND Obtained informed consents by donor or donor legally authorized representative prior to donor collection.
A patient meeting any of the following criteria is not eligible for the present study:
. Patient with acute > grade 2 or extensive chronic GVHD at the time of CTL infusion Patient receiving (>0.5 mg/kg prednisone equivalent) at the time of CTL infusion Patient treated with donor lymphocyte infusion (DLI) within 4 weeks prior to CTL infusion Patient with poor performance status determined by Karnofsky (patients >16 years) or Lansky (patients ≤16 years) score ≤30% Concomitant enrollment in another experimental clinical trial investigating the treatment of adenovirus infection(s) Any medical condition which could compromise participation in the study according to the investigator's assessment Known infection Female patient of childbearing age who is pregnant or breast-feeding or not willing to use an effective method of during study treatment.
Known to iron dextran Patients unwilling or unable to comply with the protocol or unable to give informed consent.
Known human anti-mouse antibodies

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.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
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.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
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.
After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.
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.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
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.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Allogeneic and autologous transplant

patients will receive CTL dose x 1 with 2.5 × 10(4) CD3/kg for matched related donor and 0.5 × 104 CD3/kg for mis-matched related donor. Patients who don't respond to the first infusion may receive up to a total 5 CTL infusions.
Drug: cytotoxic t-lymphocytes
adenovirus specific cytotoxic t-lymphocytes will be collected and manufactured from HLA matched related or HLA mis-matched related donors and administered to eligible patients with refractory adenovirus or PID.
Also known as: viral specific CTLs
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]
Patients will be followed for adverse events following each infusion of ADV CTLs
Time frame: 12 weeks after each infusion
Incidence of Response to Treatment (Efficacy)
Patients will be followed for improvement in viral infection by monitoring ADV PCR weekly for response to treatment with CTLs
Time frame: 12 weeks after last infusion
