A chorus of concern over the cost of prescription drugs for both patients and the health system has been growing louder. Spending on prescription drugs surged 13% last year to a record $374 billion, according to a report from IMS Institute for Healthcare Informatics (http://bit.ly/1DzzWMw). That’s the largest increase in the pace of prescription drug spending since 2000-2001, when drug spending rose by 16%, and significantly faster than the 6.8% spending growth projected by the Centers for Medicare & Medicaid Services (CMS) (http://go.cms.gov/1G35bAD).

Much of the attention has been focused on 2 new drugs introduced by Gilead Sciences in 2013 (Solvadi; the highest-selling drug in 2014 at $7.9 billion, according to the IMS report) and 2014 (Harvoni) for treating hepatitis C virus (HCV) infection, as well as other new biologic or specialty drugs for cancer, diabetes, and multiple sclerosis. The recommendation by a US Food and Drug Administration (FDA) panel in June 2015 to approve 2 injectable cholesterol-lowering drugs is certain to keep the questions that are raised by the costs of these new drug types front and center.
But the reasons for the prescription drug–spending increases are more complicated than simply the introduction of the 2 new HCV medications. The number of people with HCV infection receiving treatment in 2014 grew by a factor of 10, but because these drugs and other HCV therapies can actually cure the disease, this type of increase is not expected to continue, as previously untreated patients are identified and treated. On the other hand, spending on diabetes, which surged 30% in 2014, is unlikely to slow, given the continuing problem of obesity in the United States (http://bit.ly/1DzzWMw). Expiring patents have slowed drug spending for the last few years, but a relatively modest number of drugs lost patent protection in 2014, contributing to the spike in drug spending.
Specialty Drugs in the Spotlight
It’s not surprising that the medicines that have garnered the most attention are the extremely expensive specialty drugs that typically target serious and complex diseases. The experience with Gilead’s new HCV drugs is especially interesting because they have been vulnerable to competitive pressure when alternative novel treatments become available, despite their patent protection. After trying to negotiate with Gilead for almost a year, Express Scripts, the largest pharmacy benefit manager, chose to cover AbbVie’s competitive HCV product, Viekira Pak, approved in late 2014, and cover the Gilead products only under certain exceptions. Viekira Pak had a list price similar to the Gilead products but AbbVie agreed to a significantly lower price, in line with the types of discounts pharmacy benefit managers and large insurers have negotiated for other drugs.
The public has been historically more sensitive to changes in drug prices—especially outpatient prescription coverage—compared with the cost of other components of health care, because insurance coverage has traditionally been more extensive for hospital use and physician services. A poll by the Henry J. Kaiser Family Foundation released on June 16 indicates that most people believe the costs of prescription drugs are “unreasonable,” with 77% citing the drug company profits and 64% citing the high cost of medical research as major factors contributing to the costs (http://bit.ly/1FZSWFW). Half of those polled said they were currently taking a prescription drug; more than three-quarters of people in this group said it was easy to pay for their prescription medicines. Even so, the Kaiser Family Foundation report noted, majorities of the public said that addressing high drug costs should be a top priority for Congress and the president.
Discussions about potential policy options need to recognize that there are dilemmas inherent in drug pricing that make this area even more challenging than elsewhere in health care. The country’s track record in getting pricing “right” in other areas of health care, such as the 2-decade battle over the formula used to determine payment for physician services for Medicare beneficiaries, has demonstrated just how difficult this can be (http://bit.ly/1cXQOXF).
The basic dilemma is that to encourage investment in innovations like prescription drugs and new biologics, the government needs to provide intellectual property protection for these products through patents. While the appropriate length of patents can be debated, they effectively provide monopoly power to the patent holders. The more unique the product, the more effective the monopoly power, although pricing products beyond certain points will lower the profits to the patent holder. Whether the specialty drug company profits are “excessive” or even unusually high is not easy to ascertain and would require calculating returns on invested capital for industries with a similar risk profile—numbers not readily available.
What is clear is that the presence of a monopoly will lead to higher prices than would be expected in a more competitive market. Further complicating appropriate pricing for drugs is the long time lag between when investments are made and when a product could potentially make it to the marketplace. This means that changing the investment patterns won't be felt until many years later.
But despite the monopoly power associated with patents, Express Scripts’ success in negotiating a lower price for AbbVie’s HCV product compared with the prices for Gilead’s new HCV drugs indicates the power that alternative therapies can have. It also suggests that expedited and efficacious reviews by the FDA for new and potentially competing biologics is one strategy to keep pressure on pricing.
Role of Third Party Payers
The role of third party payers in health care also complicates getting the pricing “right.” Because most insured people are not paying the full cost of a drug (or paying nothing out of pocket at all, in many cases), the usual indication of value that consumers find in other markets is absent.
Now, however, discussions of trying to provide information about approximate value of new oncology drugs to patients, even explicitly discussing the concept of value in oncology, are receiving increased attention. For example, the American Society for Clinical Oncology (ASCO) recently published a conceptual value framework to help physicians and patients better assess the value of new cancer treatment options based on clinical benefit, adverse effects, and cost (http://bit.ly/1GxpfMJ). All of this was unimaginable just a few years ago.
It remains to be seen whether clinicians and patients will be comfortable using concepts of value when choosing among oncologic drugs or when weighing other therapeutic products. But the fact that these issues are even being discussed indicates a new willingness to consider concepts of value when considering competing therapies—and represents an important first step in improving the value of health care provided to even the sickest patients.
