Analysis of Availability and Access of Anti-myeloma Drugs and Impact on the Management of Multiple Myeloma in Latin American Countries.

INTRODUCTION: Latin American countries (LATAMC) represent a large fraction of patients treated for multiple myeloma (MM) worldwide. In order to understand the difficulty of access to anti-myeloma therapy in LATAMC, we designed this study that explores areas involved in the availability of drugs, such as health care systems, approval times, coverage of new agents, old drugs, use of generics, and the first-line treatments.
MATERIAL AND METHODS: We collected data from 16 countries in 2015.
RESULTS: The majority of LATAMC (88%; n = 14) had mixed public and private coverage, with patients with MM cared for in public institutions. Although bortezomib and lenalidomide were approved in 100% and 73% in LATAMC, these figures did not translate to real-world practice as one-half of the nations reported unequal access to the new agents (thalidomide, bortezomib, and lenalidomide) in both public and private systems. Conversely, cheaper old drugs, represented by melphalan, were not available commercially in 44% (n = 7) of nations. Thus, first-line MM treatments for old and young patients in public practice were triplets with thalidomide-alkylating agent-steroid, whereas in private practice, treatments involved bortezomib-alkylating agent-steroid. An alarming rate of 30% of the nations reported suboptimal regimens (eg, VAD [vincristine, adriamycin, and dexamethasone]) or the impossibility of transplantation.
CONCLUSION: Our data indicates that bortezomib and transplant are still an unmet medical necessity in public systems. In the complex puzzle of myeloma drug access in LATAMC, important issues, such as the adjustment of disparities between health systems, the incorporation of new drugs with an economic cost-effectiveness view, and the re-establishment of essential old drugs, can be a platform to the future.
