Thalidomide and Dexamethasone as Maintenance Therapy After Stem Cell Transplant in Multiple Myeloma
Thalidomide Plus Dexamethasone as Maintenance Therapy for Multiple Myeloma
This multicenter, prospective, randomized trial was designed to evaluate the role of thalidomide with or without dexamethasone as a maintenance therapy for multiple myeloma patients after a single autologous stem cell transplantation.
Patients were recruited prior to receiving induction therapy, and randomization in a 1:1 ratio occurred on day 60 post-autologous stem cell transplantation. The treatment consisted of the following four phases:
induction with 3–5 cycles of vincristine plus doxorrubicin and dexamethasone (VAD) every 21–28 days: vincristine 0.4 mg , doxorubicin 9 mg/m² and oral dexamethasone 40 mg daily for 4 days;
cyclophosphamide (4 g/m2 ) plus filgrastim (G-CSF) (5 μg/kg twice a day) for stem cell mobilization;
melphalan (200 mg/m2 ) and one autologous stem cell transplant (ASCT);
Sixty days (D +60) after ASCT: RANDOMIZATION in two arms of maintenance: Arm A (oral dexamethasone alone 40 mg/d for 4 days every 28 days) and Arm B (dexamethasone plus thalidomide 200 mg daily by mouth) for 12 months or until disease progression.
