Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Donor derived dendritic cells (DC) pulsed with cytomegalovirus (CMV) antigen and/or CMV antigen specific T cells will be injected into patients following haemopoietic stem cell transplantation. There will be 3 arms: Arm 1 - CMV cytotoxic T lymphocyte (CTL) infusion only; Arm 2 - DC vaccine with CMV cytotoxic T lymohocyte infusion; Arm 3 - DC vaccination only.
Doses are:
CMV cytotoxic T lymphocytes - 2x10^7 per square metre of body surface area once post transplant
DC vaccine - 2x10^6 per sqaure metre of body surface area twice at 7 day interval

Comparator / control treatment
The DC+CMV CTL arm will be compared with DC alone and CMV CTL alone. These will all be compared with historical controls.

Outcomes
Primary outcome [1] 4387 0
Safety - acute toxicity. Measured by clinical history, physical examination and observation of vital signs before, during and for 4 hours after the infusion of lymphocytes or injection of dendritic cells.
Timepoint [1] 4387 0
4 hours post infusion/injection.
Primary outcome [2] 4394 0
Safety - graft vs host disease. Measured by a standard clinical grading system as grade I-IV.
Timepoint [2] 4394 0
12 months post infusion/injection
Primary outcome [3] 4395 0
Safety - progressive disease. Measured by the detection of recurrent malignancy on full blood examination or bone marrow biopsy.
Timepoint [3] 4395 0

Secondary outcome [1] 7402 0
Use of antiviral therapy
Timepoint [1] 7402 0
