Overview
Brief Summary
This is a prospective, multicenter phase II trial designed to determine efficacy and safety of a combination chemotherapy consisting of Bendamustine + Dexamethasone + Thalidomide in patients with multiple myeloma (MM) after treatment with lenalidomide and bortezomib or which are ineligible to one of these drugs.
Detailed Description
Eligible patients will be treated according to the following scheme until the occurrence of maximum response, dose limiting toxicity or disease progression. Repeat cycles every 28 days for a maximum of 6 cycles and a minimum of 4. * Bendamustine 60 mg/m2 i.v. days 1, 8, 15 * Dexamethasone 20 mg p.o. days 1,8 , 15, 22 * Thalidomide 100 mg daily p.o. days 1-28; initial dose of 50 mg/day, with an increment to 100 mg after the first 15 days of treatment.
