Carfilzomib for the Treatment of Multiple Myeloma: Systematic Review of the Literature and Colombian Experience Based on RIPS

Abstract

Introduction: Multiple myeloma is a B-cell malignant and progressive tumor, associated with osteolytic lesions, immunodeficiency and renal dysfunction, that has been treated since 2008 with Bortezomib, which achieved an increase in patients survival, however its use was limited due to dose dependent adverse effects, especially painful peripheral neuropathy, it has recently come into use Carfilzomib (a second generation proteasome inhibitor agent) approved by the FDA in 2012 as the only agent for treatment of refractory disease and relapsing of multiple myeloma. Objective: To conduct a literature review and determine the Colombian experience with the drug Carfilzomib, considering national statistics contained in the individual records of health service delivery, plus the status of a case is described. Methodology: for the review was considered literature indexed in PubMed, as an inclusion criterion was considered clinical studies Phase 2 and 3 that reviewed Carfilzomib in handling multiple myeloma. Regarding the Colombian experience, taking information provided by Biotoscana, 37 multiple myeloma Colombian patients diagnosed between 2003 and 2012 and who had been prescribed Carfilzomib were identified. Results: A total of eight randomized trials shown on hematologic adverse effects such as fatigue (367 of 678 patients, 54%), and nausea (323 patients, 48%). For the RIPS of 37 patients, 22 patients received 1 to 8 cycles Carfilzomib (3.0 average, median 3). Clinical response in 9 of them, 4 patients (22%) very good partial response, 4 patients (22%) partial response, 1 patient (6%) with stable disease was assessed. Conclusions: We found difference between the side effects reported in Colombia from the ones who have been reported globally, fatigue prevails in our patients, also experience with new drugs has not been sufficiently documented. [Castañeda C, Pantoja MC, Montaño L, Rosselli D.
