Bortezomib, Lenalidomide, and Dexamethasone Combination Therapy for Patients With Relapsed or Relapsed and Refractory Multiple Myeloma
- Conditions
- Multiple Myeloma

- Registration Number
- NCT00378209
- Lead Sponsor
- Dana-Farber Cancer Institute
- Brief Summary
The purpose of this study is to evaluate the effectiveness and side effects of the bortezomib, lenalidomide and dexamethasone combination in relapsed or relapsed and refractory multiple myeloma. Each of these drugs are approved by the U.S Food and Drug Administration, but have not been approved in the combination for treating patients in this setting.
- Detailed Description
* Participants took the study medication in the clinic on Cycle 1 day 1. Each treatment cycle lasted three weeks. They took the lenalidomide (capsules) every day for the first two weeks only (days 1-14). They took dexamethasone (tablets) on Day 1, 2, 4, 5, 8, 9, 11 and 12 and came to the outpatient treatment center for intravenous bortezomib on Day 1, 4, 8 and 11. The third week of the cycle was a rest period and the participant did not take any study medication.
* Certain tests and procedures were performed throughout each treatment cycle at definitive time periods. These tests included: medical history update, physical/neurological examination, skeletal survey (x-rays or scan), blood samples, urine samples, optional bone marrow aspiration/tissue biopsy, 12-lead ECG, and MRI/CT (if needed).
* It was expected that participants were going to complete at least 8 cycles of the study, which adds up to 168 days. If the participant completed the first 8 cycles, had stable or responding disease and had not experienced bad side effects, they were allowed to continue treatment on a maintenance schedule, detailed in the protocol, at the study doctor's discretion.

- Primary Outcome Measures
Name Time Method The Proportion of Patients Alive and Without Progressive Disease (PD) for ≥6 Months 6 months after therapy Response assessed by the European Group for Blood and Marrow Transplant (EBMT) criteria, modified to include nCR and VGPR from the international uniform response criteria (IMWG).
Progressive disease (PD) required one or more of the following:
\>25% increased in serum monoclonal paraprotein (must also be an absolute increase of at least 5 g/L and confirmed on a repeat investigation) \>25% increased in 24-hour urinary light chain excretion (must also be an absolute increase of at least 200 mg/24 h and confirmed on a repeat investigation) \>25% increased in plasma cells in a bone marrow aspirate or on trephine biopsy (must also be an absolute increase of at least 10%) Definite increase in the size of existing lytic bone lesions or soft tissue plasmacytomas.
Development of new bone lesions or soft tissue plasmacytomas (not including compression fracture).
Development of hypercalcemia (corrected serum calcium \>11.5 mg/dL or 2.8 mmol/L not attributable to any other cause).
- Secondary Outcome Measures
Name Time Method Progression Free Survival aassesed at a median follow-up of 44 months Progression-free survival is defined as the time from registration to the disease progression or death from any cause, censored at date last known progression-free for those who have not progressed or died.
Objective Response Rate Assessed every cycle for up to 8 cycles and best response was reported Response assessed by the European Group for Blood and Marrow Transplant (EBMT) criteria, modified to include nCR and VGPR from the international uniform response criteria (IMWG).
Objective response was defined by the achievement of at least Partial Response (PR) or better (CR-complete response, nCR-near complete response, and VGPR-very good partial response).Overall Survival assesed at a median follow-up of 44 months defined as time from treatment initiation to death, or last known to be alive for those who had not died
Duration of Response Assessed at a median follow-up of 44 months Duration of response will be measured as the time from initiation of a response to first documentation of disease progression or death, or date last known progression-free and alive for those who have not progressed or died.
