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.
Interventions
Given intravenously on days 1,4,8 and 11 of a 21-day cycle for a minimum of 8 cycles.
Taken orally once a day for 2 weeks (days 1-14) of a 21-day cycle for a minimum of 8 cycles
Taken orally on days 1,2,4,5,8,9,11,and 12 of a 21-day cycle for a minimum of 8 cycles

| Lenalidomide, Dexamethasone, Bortezomib Combination Patients were treated for up to 8 21-day cycles with the combination of bortezomib 1.0 mg/m2 IV, days 1, 4, 8, and 11, and oral lenalidomide 15 mg/day, days 1 through 14, with oral dexamethasone 40 mg/day (cycles 1-4) and 20 mg/day (cycles 5-8) on the days of and days after bortezomib dosing (days 1, 2, 4, 5, 8, 9, 11, and 12).Following a protocol amendment , dexamethasone dosing was reduced to 20 mg/day in cycles 1 through 4 and 10 mg/day in cycles 5 through 8.
Beyond cycle 8, responding patients and those with stable disease (SD) could receive maintenance therapy until disease progression or unacceptable toxicity. Maintenance therapy comprised bortezomib and lenalidomide at the doses tolerated on completion of cycle 8, with lenalidomide on days 1 through 14 and using an amended schedule of weekly bortezomib (days 1 and 8) and dexamethasone 10 mg on days 1, 2, 8, and 9. | 64 |
