Pomalidomide/Cyclophosphamide/Dexamethasone in Relapse Refractory Myeloma: Safety Profile in Mexicans

Summary

Despite available therapies, MM uniformly fatal and participants who have received prior lenalidomide (Len) and bortezomib have a median overall survival (OS) of 9 months. Pomalidomide (Pom) plus low-dose dexamethasone (Dex) significantly improved efficacy parameters in terms of progression free survival (PFS), OS, and overall response (ORR) compared with high-dose Dex in participants with refractory or relapsed, and refractory MM, including participants with disease refractory to both bortezomib and lenalidomide. Alkylating agents also represent standard therapies for participants with MM. There are some reports demonstrating combination of Len and continuous cyclophosphamide (Cy) achieve an ORR of 50% in Len refractory participants, suggesting Cy may be able to overcome resistance to Len. The investigators aimed to assess the safety in Mexican MM participants in relapse/refractory stage of the triple combination: IV Cy in combination with Pom plus Dex until disease progression. A multicenter study is proposed. Primary endpoint: Safety. Efficacy as secondary endpoint: PF, OS and ORR.
