Abstract : After failure of erythropoiesis-stimulating agents ESAs, lenalidomide LEN yields red blood cell RBC transfusion independence TI in 20-30% of lower-risk non-del5q myelodysplastic syndrome MDS. Several observations suggest an additive effect of ESA and LEN in this situation. We performed a randomized phase III study in 131 RBC transfusion-dependent TD, median transfusion requirement six RBC units per 8 weeks lower-risk ESA-refractory non-del5q MDS. Patients received LEN alone, 10 mg per day, 21 days per 4 weeks L arm or LEN same schedule + erythropoietin EPO beta, 60,000 U per week LE arm. In an intent-to-treat ITT analysis, erythroid response HI-E, IWG 2006 criteria after four treatment cycles primary end point was 23.1% 95% CI 13.5-35.2 in the L arm and 39.4% 95% CI 27.6-52.2 in the LE arm P=0.044, while RBC-TI was reached in 13.8 and 24.2% of the patients in the L and LE arms, respectively P=0.13. Median response duration was 18.1 and 15.1 months in the L and LE arms, respectively P=0.47. Side effects were moderate and similar in the two arms. Low baseline serum EPO level and a G polymorphism of CRBN gene predicted HI-E. Combining LEN and EPO significantly improves erythroid response over LEN alone in lower-risk non-del5q MDS patients with anemia resistant to ESA
