简要总结
This study aims to study the efficacy and safety of oral cyclophosphamide in addition to carfilzomib and dexamethadone for RRMM patients who have been previously exposed to lenalidomide combination therapies.
详细描述
The survival of multiple myeloma (MM) patients has been improved significantly owing to the adoption of immunomodulatory agents (IMiD) and proteasome inhibitors (PI). However, most of the MM patients finally experience relapse of refractoriness of the disease, of which patients who relapse after bortezomib and lenalidomide have very poor prognosis. Carfilzomib is an irreversible second generation PI which is approved by Korean FDA for RRMM in combination with dexamethasone and/or lenalidomide based on the landmark studies ASPIRE and ENDEAVOR studies. The addition of intravenous cyclophosphamide to carfilzomib has recently showed a promising result for RRMM patients after bortezomib and lenalidomide. In this study, cyclophosphamide 50mg orally will be added to carfilzomib once weekly schedule for 21 days daily every 4 weeks. The rationale for oral metronomic cyclophosphamide is based on previous experimental studies which has shown that it removes CD4+CD25+regulatory T cells preserving T and NK/T cell funtions.
