Clinical Grade Adenovirus Specific T Cells for Immunotherapy After Allogeneic Stem Cell Transplantation (CTL-ADV) (CTL-ADV)
Adenovirus Infection
About this trial
This is an interventional treatment trial for Adenovirus Infection focused on measuring Adenovirus
Eligibility Criteria
Inclusion Criteria:
- Study Population : adults or children
- Allogeneic hematopoietic stem cell (bone marrow and peripheral blood stem cell, umbilical cord blood (UCB))
- sibling or matched unrelated donors 10/10 or 9/10 ((M)MUD) or haploidentical donor in case of UCB transplantation
Within 18 months after HSCT, occurrence of:
- An adenovirus infection without clinical symptoms (except fever with unknown origin) definitively due to this infection, after treatment failure during at least 2 weeks with Cidofovir (5 mg/kg/week).
To determine ADV infection, 2 consecutive viremia performed at 4 days interval must be higher than viral threshold of 500 copies/mL (with significant increase between these 2 analysis and at least 0, 5 log when the first viremia is equal to 500 cp/mL).
- Probable or definitive adenovirus infection after Cidofovir treatment failure, 5 mg/kg/week (according to Wisconsin's criteria)
- and/or renal toxicity or major intolerance to anti-viral drug
- and/or in case Cidofovir is not available in France
- Acute or Chronic GVHD with acute form grade II or less, controlled after 2 lines of treatment at the most.
Or controlled Chronic GVHD
- Life expectancy > 1 month at the time of inclusion
Exclusion Criteria:
- Graft failure
- Derogatory HSCT
- Acute or Chronic GVHD in acute form with grade > II, uncontrolled after 2 lines of immunosuppressive agents.
- Patients with grade > III clinical or biological toxicities (according to OMS classification)
- Chronic GVHD uncontrolled
- Immediate life-threatening
- Patients have not signed informed consent

Arms of the Study
Arm 1
Experimental
Infusion of ADV specific T cells
This one arm study consists in ADV-specific T cell infusion after HSCT from a (M)MUD or, for the first time, from a haploidentical donor for patients having undergone previous UCB transplantation, in the event of refractory ADV infection or disease. Specific anti-ADV immune reconstitution was observed in all patients, and viral load clearance in all but one.
