Autologous Bone Marrow Transplantation (BMT) Compared With Allogeneic BMT in Multiple Myeloma

This is an interventional treatment trial for Multiple Myeloma focused on measuring MM Read More

Inclusion Criteria:

• Age at diagnosis equal or under 55 year
• Meeting the Durie and Salmon criteria for initial diagnosis of MM
• Stage II or III MM at diagnosis or anytime thereafter
• Symptomatic MM requiring treatment at diagnosis or anytime thereafter
• If receiving chemotherapy-based mobilization regimens, must be able to receive high-dose melphalan between 2 and 8 weeks after the initiation of mobilization therapy whether delivered at the transplant center or at a referring center

• Adequate organ function as measured by:

  • Cardiac: Left ventricular ejection fraction at rest greater than 40%
  • Hepatic: Bilirubin less than 2 times the upper limit of normal and ALT and AST less than 3 times the upper limit of normal
  • Renal: Creatinine clearance greater than 40 ml/min (measured or calculated/estimated)
  • Pulmonary: DLCO, FEV1, and FVC greater than 50% of predicted value (corrected for hemoglobin), or O2 saturation greater than 92% of room air
• An adequate autologous graft defined as a cryopreserved PBSC graft containing at least 4.0 x 10^6 CD34+ cells/kg patient weight; if prior to enrollment it is known that a patient will be on the auto-allo arm (i.e., a consenting, eligible HLA-matched sibling donor is available), the required autograft must contain at least 2.0 x 10^6 CD34+ cells/kg patient weight; the graft may not be CD34+ selected or otherwise manipulated to remove tumor or other cells; the graft can be collected at the transplanting institution or by a referring center; for patients without an HLA-matched sibling donor, the autograft must be stored so that there are two products each containing at least 2 x 10^6 CD34+ cells/kg patient weight

Exclusion Criteria:

• Never advanced beyond Stage I MM since diagnosis
• Non-secretory MM (absence of a monoclonal protein [M protein] in serum as measured by electrophoresis and immunofixation and the absence of Bence Jones protein in the urine defined by use of conventional electrophoresis and immunofixation techniques)
• Plasma cell leukemia
• Karnofsky performance score less than 70%, unless approved by the Medical Monitor or one of the Protocol Chairs
• Uncontrolled hypertension
• Uncontrolled bacterial, viral, or fungal infections (currently taking medication and progression of clinical symptoms)
• Prior malignancies except resected basal cell carcinoma or treated cervical carcinoma in situ; cancer treated with curative intent less than 5 years previously will not be allowed unless approved by the Medical Monitor or one of the Protocol Chairs; cancer treated with curative intent more than 5 years previously will be allowed
• Pregnant or breastfeeding
• Seropositive for the human immunodeficiency virus (HIV)
• Unwilling to use contraceptive techniques during and for 12 months following treatment
• Prior allograft or prior autograft
• Received mid-intensity melphalan (more than 50 mg IV) as part of prior therapy
• Prior organ transplant requiring immunosuppressive therapy
