- Time frame
- Assessed every cycle (1 cycle=28 days) for the first 12 cycles, and then every 2 cycles while on treatment. Post treatment assessed every 3 months < 2 years from study entry, every 6 months if 2-5 years, every 12 months if 6-10 years from study entry.
What was measured
Response evaluation was based on the International Myeloma Working Group (IMWG) response criteria. VGPR rate was defined as patients achieving at least VGPR which include patients who achieving complete response (CR) and VGPR. CR refers to patients who have complete disappearance of an M-protein and no evidence of myeloma in the bone marrow. VGPR refers to patients who meet the following criteria: Serum and urine M-component detectable by immunofixation but not on electrophoresis; Or 90% or greater reduction in serum M-component plus urine M-component \<100 mg per 24 hours; If the serum and urine M protein are unmeasurable and the immunoglobulin free light chain parameter is being used to measure response, a ≥ 90% decrease in the difference between involved and uninvolved free light chain (FLC) levels is required in place of the M protein criteria.
Analysis population: Intention-to-treat (ITT) population
Groups in this outcome
Arm I (MPT-T)
Patients receive melphalan, prednisone and thalidomide induction plus thalidomide maintenance (MPT-T). INDUCTION THERAPY: Patients receive melphalan PO and prednisone PO daily on days 1-4, and thalidomide PO daily on days 1-28. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. MAINTENANCE THERAPY: Patients receive thalidomide PO daily and continue in the absence of disease progression.
Arm II (mPR-R)
Patients receive lower-dose melphalan, prednisone and lenalidomide (Revlimid®) induction plus lenalidomide maintenance (mPR-R). INDUCTION THERAPY: Patients receive melphalan PO and prednisone PO daily on days 1-4, and lenalidomide PO on days 1-21. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. MAINTENANCE THERAPY: Patients receive lenalidomide PO daily on days 1-21. Courses repeat every 28 days in the absence of disease progression.
