Graft versus host disease (GVHD) is one of the common complications after stem cell transplant. This is a complication, which happens when the new stem cells from the donor attack other cells in the body of the transplant recipient.

Recently, an antibody (protein) called alemtuzumab or Campath has been found to be effective in the prevention of Graft vs. Host Disease.

Previous studies have shown a low risk of GVHD with alemtuzumab, however the risk of disease recurrence was high. Previous studies have used a high dose of alemtuzumab. The purpose of this study is:

  • To find if by lowering the dose of alemtuzumab, can serious GVHD be prevented without increasing the risk of relapse (your condition getting worse).
  • To find whether low dose of alemtuzumab in combination with cyclosporine can prevent GVHD more effectively when compared to current standard of care and does not increase the risk of recurrence.

Primary Outcome Measures:
  • Chronic extensive GVHD at 1-year (yes vs. no) [ Time Frame: 12 months from the date of transplant ]

Enrollment: 78
Study Start Date: October 2008
Study Completion Date: September 2010
Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Standard of Care
The current standard of care for GVHD prophylaxis at Princess Margaret Hospital is cyclosporine and Mycophenolate or cyclosporine and methotrexate.
Drug: mycophenolate or cyclosporine and methotrexate
One of the two GVHD prophylaxis used at PMH-either cyclosporine and mycophenolate or cyclosporine and methotrexate
Experimental: Cyclosporine and Campath
The efficacy of experimental arm will be tested against standard of care for prevention of Chronic extensive GVHD.
Drug: Alemtuzumab
A new GVHD prevention strategy will be tested against established GVHD prophylaxis in patients undergoing matched sibling donor transplant using peripheral blood stem cells.
