The feasibility and efficacy of a triple regimen of oral weekly cyclophosphamide, monthly pulsed dexamethasone and low-dose Thalidomide (CDT) was studied in 52 patients with relapsed or refractory multiple myeloma (MM). All 52 patients were evaluable for response with a median follow up of 18 (4-29) months. About 17% achieved complete response (CR), 62% partial response (PR), 11% minimal response (MR), 6% stable disease (SD) and 4% progressive disease (PD), resulting in an objective response rate (>/=MR) of 90%. Subsequent to successful response, nine patients received high-dose therapy (HDT) followed by stem cell transplantation (SCT) and 34 received thalidomide monotherapy as maintenance. Response rate was not influenced by disease status, prior HDT or age. The regimen was successfully delivered to all patients except for one patient who developed abnormal liver function at 7 weeks. Infective complications were minimal and there were no infection-related deaths. The estimated overall and event-free survival (EFS) at 2 years was 73% and 34%, respectively, and the median time to progression has not been reached. We conclude that the CDT regimen is safe, well tolerated and effective in patients with relapsed and refractory myeloma.
