For two decades, patients and physicians eagerly awaited a lower-cost version of the world’s bestselling drug, Humira, while its maker, AbbVie, fought off potential competitors by building a wall of more than 250 patents around it.
When the first Humira biosimilar — essentially a generic version — finally hit the market in January, it came with an unpleasant surprise. The biosimilar’s maker, Amgen, launched two versions of the drug, which treats a host of conditions including rheumatoid arthritis. They were identical in every way but this: One was priced at about $1,600 for a two-week supply, 55% off Humira’s list price. But the other was priced at around $3,300, only about 5% off. And OptumRx, one of three powerhouse brokers that determine which drugs Americans get, recommended option No. 2: the more expensive version.
As Murdo Gordon, an Amgen executive vice president, explained in an earnings call, the higher price enabled his company to give bigger rebates, or post-sale discounts, to Optum and other intermediaries. Most of that money would be passed on to insurers, and patients, he said. Gordon did not mention that the higher-priced option would leave some patients paying much more out-of-pocket, undermining the whole rationale for generic drugs.
The Optum-Amgen announcements perfectly elucidated why, after years of thundering against drugmakers, Congress and the administration have now focused on regulating the deal-makers known as pharmacy benefit managers, or PBMs. Sen. Bernie Sanders’ health committee grilled a panel of PBM and pharmaceutical executives Wednesday in preparation for a vote on PBM legislation, expected Thursday.
The three biggest PBMs — OptumRx, CVS Caremark, and Express Scripts — control about 80% of prescription drug sales in America and are the most profitable parts of the health conglomerates in which they’re nestled. CVS Health, the fourth-largest U.S. corporation by revenue on Fortune’s list, owns CVS Caremark and the insurer Aetna; UnitedHealth Group, a close fifth, owns Optum; and Cigna, ranking 12th, owns Express Scripts. While serving as middlemen among drugmakers, insurers, and pharmacies, the three corporations also own the highest-grossing specialty drug and mail-order pharmacies.
“John D. Rockefeller would be happy to be alive today,” said David Balto, a former Federal Trade Commission attorney who represents clients suing PBMs. “He could own a PBM and monopolize economic power in ways he never imagined.”
Drug manufacturers claim that exorbitant PBM demands for rebates force them to set high list prices to earn a profit. Independent pharmacists say PBMs are driving them out of business. Physicians blame them for unpredictable, clinically invalid prescribing decisions. And patients complain that PBMs’ choices drain their pocketbooks.
With PBMs driving prices, competition has had the opposite effect from what economic theory predicted Medicare patients would spend out-of-pocket on drugs, one large study showed. Over a five-year period, patients were paying 50% more for branded drugs that had competitors than for those that didn’t.
All this makes the PBMs ripe targets for politicians of both parties. Yet the complexity and obscurity of their role in the drug marketplace have skeptics wondering whether legislation advancing in the House and Senate will actually help patients or lower prices at the pharmacy counter.
“We may try to make things better and actually make things worse,” Sen. Rand Paul (R-Ky.) said at Wednesday’s hearing.
