News Briefs: CMS Rescinds Most Favored Nation Model | Jan. 13, 2022

CMS issued a final rule on Dec. 29 that rescinded the Most Favored Nation model. The mandatory model would have priced Medicare Part B drugs on the U.S. market based on their prices in certain countries. An interim final rule that was published in November 2020 had been blocked from being implemented on Jan. 1, 2021.

CMS published a proposed rule on Jan. 12 that would rein in direct and indirect remuneration (DIR) fees, which pharmacies have long complained about. The proposal would save consumers about $21.3 billion but cost the federal government $40.0 billion from 2023 through 2032.

Study: Opportunities to Improve Management of PNH Exist

Paroxysmal nocturnal hemoglobinuria (PNH) is an ultra-rare, potentially fatal disease. The FDA approved the first therapy, Alexion Pharmaceuticals, Inc.’s Soliris (eculizumab), a complement C5 inhibitor (C5I), to treat adults with the condition on March 16, 2007. Then the agency approved another C5I to treat adults with PNH from the same company, Ultomiris (ravulizumab-cwvz), on Dec. 21, 2018. A recent study of those two therapies from Prime Therapeutics LLC shows that there may be opportunities for payers in PNH management that will result in better health care outcomes for their members.

Prime presented findings from the study at the Academy of Managed Care Pharmacy (AMCP) Nexus meeting, which was held Oct. 18 through 21 in Denver. Funding for the study was provided by Apellis Pharmaceuticals, Inc., manufacturer of Empaveli (pegcetacoplan), a C3 inhibitor approved May 14, 2021, for the treatment of PNH in treatment-naïve people, as well as ones switching from any C5I. Researchers were from Prime, Apellis and the University of Minnesota College of Pharmacy.
