Consensus statements from a panel of U.S. managed care pharmacists and physicians for management of multiple sclerosis agents.

■■ Consensus Statements from a Panel of U.S. Managed Care Pharmacists and Physicians for Management of Multiple Sclerosis Agents Miller et al. (“Approaches to the Management of Agents Used for the Treatment of Multiple Sclerosis: Consensus Statements from a Panel of U.S. Managed Care Pharmacists and Physicians”) published in the January/February 2012 issue of JMCP present the results of a modified Delphi panel regarding formulary management of disease-modifying therapies (DMTs) for the treatment of multiple sclerosis (MS). The authors have noted that none of the participants had clinical practice experience treating MS patients, yet emphasized that all participants were considered experts in managed care. We commend the authors in consolidating and communicating prevailing opinions among U.S. payers in the management of access to MS therapies, however the explicit absence of MS expert clinical input renders the conclusions less robust. Given the complexity and heterogeneity of MS, we question the clinical validity and appropriateness of the panel’s opinion, particularly when the consequences of such decisions may have a significant effect on the health of plan members. To that end we wish to call attention to several concerns regarding the panel’s process and methods related to interpretation of the existing literature, which appears to be biased against fingolimod. • Funding for the project by Biogen Idec, a manufacturer of 2 of the products under consideration, is adequately described, but there is no description of the manufacturer’s role in reviewing the questions, survey data, or attendance at the live meeting. We would appreciate fuller transparency in this matter to resolve any issues relating to conflict of interest. • A “platform therapy” is any DMT “that can be initiated and continued on a long-term basis.” Fingolimod was not considered a “platform therapy” in the research despite published 1and 2-year pivotal studies, demonstrating the safety and efficacy in extended use, supplemented by published 3-year follow-up data. Although long-term real-world data do not exist on fingolimod, as with any newly approved agent, all of these publications support inclusion of fingolimod as a platform therapy and were available at the time the project was initiated. It would be worthwhile to clarify the definition used by the authors for inclusion under “platform therapy.” • The panel reached consensus that “if efficacy and safety are judged comparable among agents, then cost and contracting should be considered.” Fingolimod demonstrated superior efficacy to weekly intramuscular interferon beta-1a in a randomized, double blind, double dummy, controlled clinical trial, reducing annualized relapse rates by 38%-52% versus the active comparator. Yet because it was inappropriately excluded from the platform therapy category, it was subsequently not considered as an alternative to low-dose/low-frequency interferons. Hence, by default or design fingolimod was relegated to a “comparable” efficacy category without direct comparison of the available data. • Questions regarding combination therapy with interferons or glatiramer acetate were applied only to fingolimod despite the absence of any clinical data of fingolimod use in combination or FDA indication, suggesting that this was evidence-based or even a consideration among clinicians. This inherently creates a bias against fingolimod by positioning it as the only DMT with the “potential” to be used in combination with other platform therapies in the absence of any data supporting this conjecture. • Cladribine, an oral immunosuppressant with demonstrated efficacy in MS, was not discussed nor mentioned despite the fact that the manufacturer’s submission was still under review by the FDA at the time of this exercise. Subsequently, cladribine was rejected by the FDA in March 2011 for the MS indication and received negative reviews in Europe; and hence might not have been included in the publication. However, clarity should be provided whether it was considered in the panel discussion. • The paper defines consensus as a mean score of 3.3 on a 4.0 point Likert scale or 100% of panelists either “strongly agree” or “agree,” but the literature does not define consensus in a Delphi process. Moreover, one of the recommendations of the panel is that “prior authorizations should be utilized by health plans to manage patient access to fingolimod” even though the panel failed to reach consensus (3.1/4.0) based on the pre-specified definition. More precise definitions of consensus are needed to interpret the panel’s findings. In summary, we agree with the authors’ conclusions that “payers are challenged to make management decisions in the MS category without clinical consensus” but disagree that, in the absence of treatment guidelines, such decisions can be responsibly made without the counsel of clinical experts in the management of MS. We believe that this panel would have been more informative if conducted with such input in a more balanced manner. Furthermore questions around the panel’s processes and data interpretation raise questions around bias and conflict of interest which require explanation.
