FEATURE Features Who Pays What, and Why? From R&D to PBMs, a look at the U.S. approach to drug pricing When it comes to setting drug prices, the U.S. is singular in its approach. The U.S. is the only nation in the developed world that does not regulate or negotiate prices of newly approved drugs as they come to market. Other countries, including most Euro- pean nations, have dedicated agencies that communicate with pharmaceutical compa- nies. These organizations scrutinize clinical data about a new drug’s efficacy and risks, then run comparative-effectiveness and cost-effectiveness analyses to score it against available therapies. Depending on the results of these analyses, the agencies issue a decision about a drug’s reimburse- ment and negotiate a set price with the drug’s manufacturer. And, for certain geographies and drugs, regional organiza- tions and hospitals also may be allowed to negotiate drug pricing. “The bottom line is that this country differs from all other developed countries in not having a process through which the federal government evaluates a new drug’s comparative effectiveness and weaves that into the funding and pricing of new drugs,” said Steven Pearson, MD, MSc, a physician, bioethicist, and the founder and president of the Institute for Clinical and Economic Review (ICER), a nonprofit health policy and comparative-effectiveness research organization based in Boston. “In the U.S., this has meant that drug prices tend to go higher, due to a mix of factors,” Dr. Pearson added. Curbing skyrocketing price hikes, therefore, will re- quire a multifaced approach. For example, ASHClinicalNews.org one solution that receives a lot of attention is bringing more generics to market, but the complexities of the U.S. drug-pricing system mean that may have little effect. “Because there is no federal process for negotiating prices and because there is so much innovation, it is difficult to have generics by themselves moderate overall spending.” ASH Clinical News spoke with Dr. Pearson and other health economists about who decides how much drugs cost, why they cost so much in the U.S., and how regulators, clinicians, and insurers are trying to rein in prices. Starting High A newly approved cancer treatment doesn’t always offer a drastic improvement in patient outcomes, which is one reason why regulatory agencies in other countries decide not to cover certain new medica- tions: A marginal improvement from available options can’t justify a substan- tially higher cost. One oft-cited case is that of aflibercept, which the U.S. Food and Drug Adminis- tration (FDA) approved to treat metastatic colorectal cancer in 2012. The drug’s manufacturer, Sanofi, initially priced the drug at about $11,000 per month of treat- ment. Then, physicians at the Memorial Sloan Kettering Cancer Center (MSKCC) in New York penned an editorial stating that their center would not use the drug, which fared no better in comparative studies than already-available, less expen- sive therapies. 1 One month later, Sanofi responded that aflibercept’s list price would not change, but the company of- fered a 50-percent discount on the price paid by doctors and hospitals. 2 Aflibercept isn’t the only extremely high-priced cancer treatment to gain na- tional attention. A 2017 analysis found that the costs of injectable cancer drugs in the U.S., including older, on-patent drugs, are increasing at rates higher than inflation. 3 Of the 24 injectable cancer drugs approved between 1996 and 2012, costs increased by an average of 25 percent. That dipped slightly to 18 percent after adjustment for inflation, or an average increase of about 6 percent per year. The inflation rate, how- ever, averaged 1 percent per year. Oral drugs that are dispensed through pharmacies directly to patients (rather than being administered by physicians) also are not immune to price hikes, according to Anna Kaltenboeck, a senior health econo- mist and program director at the Drug Pricing Lab at MSKCC. “Inflation among drugs administered by physicians gener- ally is more bounded than it is for drugs dispensed through the pharmacy.” For example, Novartis’s imatinib, used for the treatment of chronic myeloid leukemia, cost $26,000 per year when it was initially approved in 2001 – a high price at the time. In 2013, even though its patent expired and generic imatinib was made available, branded imatinib cost more than $120,000 per year. In 2016, that figure again jumped to $146,000 per year. 4 It appears that drug prices start out high and only get higher. The eventual list price is something drug manufactur- ers begin thinking about years before the drug is likely to come to market, while it is still in the early stages of development. “One reason cancer drugs demand high prices is that some of them have no competition – they are the only game in town,” Ms. Kaltenboeck said. “Cancer drugs also fall into a protected class, under Medicare Part D, which means that plans have to cover all or a substantial number of these drugs, which also means that health plans lose negotiating leverage on these products.” Some researchers have suggested that pharmaceutical companies defend their high drug prices based on the high costs of drug development. A 2016 analysis from the Tufts Center for the Study of Drug Development estimated that the cost of bringing a medicine from the laboratory to the pharmacy is $2.7 billion. 5 Companies may set their prices to cover those costs. However, Ms. Kaltenboeck, who has consulted for pharmaceutical manufac- turers in the past, rejects that claim. “The diligence to gauge a drug’s pricing and revenue potential starts before clinical development to make sure it’s worth the investment. By the time a price is deter- mined, which happens much later, it’s just not a part of the conversation.” What Does a Drug Really Cost? While other countries have a central agency that negotiates a price, in the U.S., pricing terms are restricted by the list price and access agreements. The system ASH Clinical News 57
