Background: Early therapeutic intervention in high-risk SMM (HR-SMM) has demonstrated benefit based on previous studies that included treatment with lenalidomide or lenalidomide and dexamethasone (Mateos et al. N Engl J Med 2013; Lonial et al. J Clin Oncol 2020). Combination therapy with triplets has shown higher rates of deep response and improved outcomes in patients with multiple myeloma, including the combination of ixazomib, lenalidomide, and dexamethasone (Moreau et al. N Eng J Med 2016). We present our results of phase II study of ixazomib, lenalidomide and dexamethasone in HR-SMM.
