Carfilzomib and pomalidomide in patients with relapsed and/or refractory multiple myeloma with baseline risk factors

Review of key results from carfilzomib and pomalidomide clinical trials in patients with relapsed and/or refractory multiple myeloma who also have baseline comorbidities or treatment-induced or disease-induced complications (e.g. presence of renal impairment, cardiac risk factors, peripheral neuropathy, or high-risk cytogenetics). Scenario-specific treatment recommendations are also provided.While survival times have increased over the last decade, most patients with multiple myeloma (MM) eventually relapse and become refractory to therapy. The treatment of patients with relapsed and/or refractory MM is frequently further complicated by the presence of pre-existing comorbidities that arise from an advanced disease state and of toxicities stemming from prior antimyeloma treatment. Carfilzomib and pomalidomide have recently been approved for the treatment of patients with relapsed and refractory MM. While these agents represent important additions to the available treatment options, the identification of patients who may best benefit from the use of each of therapy is still being investigated. A number of patient-related and disease-related factors may impact treatment efficacy and/or tolerability, and the clinical presentation and medical history of each patient must be carefully considered to optimize treatment. Here, we review results from carfilzomib and pomalidomide clinical trials in patients with relapsed and/or refractory MM who also have baseline comorbidities or treatment-induced or disease-induced complications (including the presence of renal impairment, cardiac risk factors, peripheral neuropathy, or high-risk chromosomal abnormalities) to evaluate the safety and efficacy of the two agents in these difficult-to-treat patients and to provide treatment recommendations specific to each scenario.
