|Study Start Date:||September 2007|
|Study Completion Date:||April 2015|
|Primary Completion Date:||February 2015 (Final data collection date for primary outcome measure)|
|Active Comparator: Cyclosporine + Methotreaxte||
Standard GVHD prophylaxis
|Active Comparator: sirolimus + tacrolimus||
Standard GVHD prophylaxis
Primary endpoint The primary endpoint is grade II-IV acute GVHD in the two groups. GVHD is diagnosed clinically and graded from 0 to IV. The diagnosis is clinical and biopsies from skin, liver and gut is used according to the routines at each participating center.
Other study parameters
- Time to neutrophils >0.5 x 109/L.
- Time to platelets >20 x 109/L and 50 x 109/L.
- Platelet level 30 days after transplant.
- Transfusion requirements of platelets, erythrocytes, granulocyte transfusions during the first 30 days.
- Non-engraftment (graft failure/rejection).
- Grade of acute GVHD.
- Incidence of chronic graft-versus-host disease graded as limited or extensive and mild, moderate and severe.
- Transplant-related mortality.
- Probability of relapse in patients with haematological malignancies.
- Relapse-free survival.
- Infections by bacteria, virus and fungi. Cytomegalovirus reactivation is also followed by PCR.
- Side-effects. Side-effects regarding hematopoiesis, liver test, renal function, cardiac function, neurology, endocrinology, etc., are taken from the patients' charts. These parameters are followed regularly after transplantation.
