Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Not specified
Study type	Treatment
Scientific title
Study acronym	GAP-Protocol
Study objectives	Allogeneic AdV-specific T lymphocytes (ASTL) can be generated and used therapeutically with a low risk of graft versus host disease (GVHD)
Ethics approval(s)	Ethical approval not yet received as of 31/03/2006
Health condition(s) or problem(s) studied	Pediatric patients with ALL, AML, CML or MDS following hematopoietic stem cell transplantation
Intervention	1. Treatment group will receive ASTL as prophylaxis and cidofovir as intervention. 2. Control group will receive placebo as prophylaxis and cidofovir as intervention.
Intervention type	Other
Primary outcome measure	To determine the treatment related mortality (TRM), this will come into effect if: 1. TRM exceeds 35% 2. Acute GVHD III/IV exceeds 25% 3. Chronic GVHD II exceeds 25% 4. Non-hematopoietic toxicity 3-5 (according to NCI CTEP reporting criteria) exceeds 40%
Secondary outcome measures	1. Acute and chronic GVHD assessed by standard clinical grading scheme 2. Early non-hematopoietic toxicity grade according to NCI CTEP common terminology criteria for adverse events 3. Frequency and duration of AdV reactivations
