  Purpose

A phase II clinical study to assess the efficacy of post-transplantation cyclophosphamide as single-agent GvHD prophylaxis after allogeneic hematopoietic stem cell transplantation in patients with multiple myeloma or lymphoma and to describe the influence of the modified immunosuppression concept on relapse rates, minimal residual disease, immune reconstitution and chimerism.

Primary Outcome Measures:
  • Number of patients not requiring additional immunosuppression [ Time Frame: day 100 after transplant ] [ Designated as safety issue: Yes ]
    The primary endpoint is met if at least 1 of the 5 first patients and 3 of a total of 11 patient will reach day 100 after transplant without additional immunsuppressive drug treatment


Secondary Outcome Measures:
  • Overall Survival [ Time Frame: day 100 after transplant ] [ Designated as safety issue: Yes ]
  • engraftment [ Time Frame: day 100 after transplant ] [ Designated as safety issue: Yes ]
    absolute neutrophil count of > 0.5 x 10e9/l on 3 consecutive days

  • chimerism [ Time Frame: day 100 after transplant ] [ Designated as safety issue: Yes ]
    Percentage of donor cells in leukocytes from peripheral blood or bone marrow

  • relapse incidence [ Time Frame: day 100 after transplant ] [ Designated as safety issue: No ]
    cumulative incidence of relapse until day 100

  • acute GvHD [ Time Frame: day 100 after transplant ] [ Designated as safety issue: Yes ]
    cumulative incidence of acute GvHD

  • non-relapse mortality [ Time Frame: day 100 after transplant ] [ Designated as safety issue: Yes ]
    cumulative incidence of death from any cause without prior relapse or progression of malignant disease

  • immune reconstitution [ Time Frame: day 100 after transplant ] [ Designated as safety issue: No ]
    relative and absolute counts of B- and T-lymphocyte subsets in peripheral blood
