Archives For drug pricing

The two-year budget plan passed last week makes important changes to payment obligations in the Medicare Part D coverage gap, also known as the donut hole.  While the new plan produces a one-year benefit for seniors by reducing what they pay a year earlier than was already mandated, it permanently shifts much of the drug costs insurance companies were paying to drug makers.  It’s far from clear whether this windfall for insurers will result in lower drug costs for Medicare beneficiaries.

Medicare Part D is voluntary prescription drug insurance for seniors and the permanently disabled provided by private insurance plans that are approved by the Medicare program.  Last year, more than 42 million people enrolled in Medicare Part D plans. Payment for prescription drugs under Medicare Part D depends on how much enrollees spend on drugs.  In 2018, after hitting a deductible that varies by plan, enrollees pay 25% of their drug costs while the Part D plans pay 75%.  However, once the individual and the plan have spent a total of $3,750, enrollees hit the coverage gap that lasts until $8,418 has been spent.  In the coverage gap, enrollees pay 35% of brand drug costs, the Part D plans pay 15%, and drug makers are required to offer 50% discounts on brand drugs to cover the rest.  Once total spending reaches $8,418, enrollees enter catastrophic coverage in which they pay only 5% of drug costs, the Part D plans pay 15%, and the Medicare program pays the other 80%.

The Affordable Care Act (ACA) included provisions to phase out the coverage gap by 2020, so that enrollees will pay only 25% of drug costs from the time they meet the deductible until they hit the catastrophic coverage level.  The budget plan passed last week speeds up this phase out by one year, so enrollees will start paying only 25% in 2019 instead of 2020.  The ACA anticipated that with enrollees paying 25% of drug costs and drug maker discounts of 50%, the Part D plans would pay the other 25%.  However, last week’s budget plan drastically redistributed the payment responsibilities from the Part D insurance plans to drug makers. Under the new plan drug makers are required to offer 70% discounts so that the plans only have to pay 5% of the total drug costs.  That is, the new plan shifts 20% of total drug costs in the coverage gap from insurers to drug makers.

Although the drug spending in each individual’s coverage gap is less than $5,000, with over 42 million people covered, the total spending, and the 20% of spending shifted from insurers to drug makers, is significant.  CMS has estimated that when drug makers’ discounts were only covering 50% of drug spending in the gap, the annual total discounts amounted to over $5.6 billion.  Requiring drug makers to cover another 20% of drug spending will add several billion dollars more to this total.

A government intervention that forces suppliers to cover 70% of the spending in a market is a surprising move for Republicans—supposed advocates of free markets.  Moreover, although reducing prescription drug costs has become a national priority, it’s unclear whether shifting costs from insurers to drug makers will benefit individuals at all.  Theoretically, as the individual Part D plans pay less of their enrollees’ drug costs, they should pass on the savings to enrollees in the form of lower premiums.  However, several studies suggest that enrollees may not experience a net decrease in drug spending.  The Centers for Medicare and Medicaid Services (CMS) has determined that under Medicare Part D, drug makers increase list prices to offset other concessions and to more quickly move enrollees out of the coverage gap where drug makers are required to offer price discounts.  Higher list prices mean that enrollees’ total out-of-pocket drug spending increases; even a 5% cost-sharing obligation in the catastrophic coverage for a high-priced drug can be a significant expense. Higher list prices that push enrollees out of the coverage gap also shift more costs onto the Medicare program that pays 80% of drug costs in the catastrophic coverage phase.

A better, more direct way to reduce Medicare Part D enrollees’ out-of-pocket drug spending is to require point-of-sale rebates.  Currently, drug makers offer rebates to Part D plans in order to improve their access to the millions of individuals covered by the plans.  However, the rebates, which total over $16 billion annually, are paid after the point-of-sale, and evidence shows that only a portion of these rebates get passed through to beneficiaries in the form of reduced insurance premiums.  Moreover, a reduction in premiums does little to benefit those enrolled individuals who have the highest aggregate out-of-pocket spending on drugs. (As an aside, in contrast to the typical insurance subsidization of high-cost enrollees by low-cost enrollees, high-spending enrollees under Medicare Part D generate greater rebates for their plans, but then the rebates are spread across all enrollees in the form of lower premiums).

Drug maker rebates will more directly benefit Medicare Part D enrollees if rebates are passed through at the point-of-sale to reduce drug copays.  Point-of-sale rebates would ensure that enrollees see immediate savings as they meet their cost-sharing obligations.  Moreover, the enrollees with the highest aggregate out-of-pocket spending would be the ones to realize the greatest savings.  CMS has recently solicited comments on a plan to require some portion of drug makers’ rebates to be applied at the point of sale, and the President’s budget plan released yesterday proposes point-of-sale rebates to lower Medicare Part D enrollees’ out-of-pocket spending.  Ultimately, targeting rebates to consumers at the point-of-sale will more effectively lower drug spending than reducing insurance plans’ payment obligations in hopes that they pass on the savings to enrollees.

Last week, several major drug makers marked the new year by announcing annual increases on list prices.  In addition to drug maker Allergan—which pledged last year to confine price increases below 10 percent and, true to its word, reported 2018 price increases of 9.5 percent—several other companies also stuck to single-digit increases.   Although list or “sticker” prices generally increased by around 9 percent for most drugs, after discounts negotiated with various health plans, the net prices that consumers and insurers actually pay will see much lower increases. For example, Allergan expects that payors will only see net price increases of 2 to 3 percent in 2018.

However, price increases won’t generate the same returns for brand drug companies that they once did.  As insurers and pharmacy benefit managers consolidate and increase their market share, they have been able to capture an increasing share of the money spent on drugs for themselves. Indeed, a 2017 report found that, of the money spent on prescription drugs by patients and health plans at the point of sale, brand drug makers only realized 39 percent.  Meanwhile, supply-chain participants, such as pharmacy benefit managers, realized 42 percent of these expenditures.  What’s more, year-after-year, brand drug makers have seen their share of these point-of-sale expenditures decrease while supply-chain entities have kept a growing share of expenditures for themselves.

Brand drug makers have also experienced a dramatic decline in the return on their R&D investment.  A recent Deloitte study reports that, for the large drug makers they’ve followed since 2010, R&D returns have dropped from over 10 percent to under 4 percent for the last two years.  The ability of supply-chain entities to capture an increasing share of drug expenditures is responsible for at least part of drug makers’ decreasing R&D returns; the study reports that average peak sales for drugs have slowly dropped over time, mirroring drug maker’s decreasing share of expenditures.  In addition, the decline in R&D returns can be traced to the increasing cost of bringing drugs to market; for the companies Deloitte studied, the cost to bring a drug to market has increased from just over $1.1 billion in 2010 to almost $2 billion in 2017.

Brand drug makers’ decreasing share of drug expenditures and declining R&D returns reduce incentives to innovate.  As the payoff from innovation declines, fewer companies will devote the substantial resources necessary to develop innovative new drugs.  In addition, innovation is threatened as brand companies increasingly face uncertainty about the patent rights of the drugs they do bring to market.  As I’ve discussed in a previous post,  the unbalanced inter partes review (IPR) process created under the Leahy-Smith America Invents Act in 2012 has led to significantly higher patent invalidation rates.  Compared to traditional district-court litigation, several pro-challenger provisions under IPR—including a lower standard of proof, a broader claim construction standard, and the ability of patent challengers to force patent owners into duplicative litigation—have resulted in twice as many patents deemed invalid in IPR proceedings.  Moreover, the lack of a standing requirement in IPR proceedings has given rise to “reverse patent trolling,” in which entities that are not litigation targets, or even participants in the same industry, threaten to file an IPR petition challenging the validity of a patent unless the patent holder agrees to specific settlement demands.  Even supporters of IPR proceedings recognize the flaws with the system; as Senator Orrin Hatch stated in a 2017 speech: “Such manipulation is contrary to the intent of IPR and the very purpose of intellectual property law. . . I think Congress needs to take a look at it.” Although the constitutionality of the IPR process is currently under review by the U.S. Supreme Court, if the unbalanced process remains unchanged, the significant uncertainty it creates for drug makers’ patent rights will lead to less innovation in the pharmaceutical industry.  Drug makers will have little incentive to spend billions of dollars to bring a new drug to market when they cannot be certain if the patents for that drug can withstand IPR proceedings that are clearly stacked against them.

We are likely to see a renewed push for drug pricing reforms in 2018 as access to affordable drugs remains a top policy priority.  Although Congress has yet to come together in support of any specific proposal, several states are experimenting with reforms that aim to lower drug prices by requiring more pricing transparency and notice of price increases.  As lawmakers consider these and other reforms, they should consider the current challenges that drug makers already face as their share of drug expenditures and R&D returns decline and patent rights remain uncertain.  Reforms that further threaten drug makers’ financial incentives to innovate could reduce our access to life-saving and life-improving new drugs.

Today, the Senate Committee on Health, Education, Labor, and Pensions (HELP) enters the drug pricing debate with a hearing on “The Cost of Prescription Drugs: How the Drug Delivery System Affects What Patients Pay.”  By questioning the role of the drug delivery system in pricing, the hearing goes beyond the more narrow focus of recent hearings that have explored how drug companies set prices.  Instead, today’s hearing will explore how pharmacy benefit managers, insurers, providers, and others influence the amounts that patients pay.

In 2016, net U.S. drug spending increased by 4.8% to $323 billion (after adjusting for rebates and off-invoice discounts).  This rate of growth slowed to less than half the rates of 2014 and 2015, when net drug spending grew at rates of 10% and 8.9% respectively.  Yet despite the slowing in drug spending, the public outcry over the cost of prescription drugs continues.

In today’s hearing, there will be testimony both on the various causes of drug spending increases and on various proposals that could reduce the cost of drugs.  Several of the proposals will focus on ways to increase competition in the pharmaceutical industry, and in turn, reduce drug prices.  I have previously explained several ways that the government could reduce prices through enhanced competition, including reducing the backlog of generic drugs awaiting FDA approval and expediting the approval and acceptance of biosimilars.  Other proposals today will likely call for regulatory reforms to enable innovative contractual arrangements that allow for outcome- or indication-based pricing and other novel reimbursement designs.

However, some proposals will undoubtedly return to the familiar call for more government negotiation of drug prices, especially drugs covered under Medicare Part D.  As I’ve discussed in a previous post, in order for government negotiation to significantly lower drug prices, the government must be able to put pressure on drug makers to secure price concessions. This could be achieved if the government could set prices administratively, penalize manufacturers that don’t offer price reductions, or establish a formulary.  Setting prices or penalizing drug makers that don’t reduce prices would produce the same disastrous effects as price controls: drug shortages in certain markets, increased prices for non-Medicare patients, and reduced incentives for innovation. A government formulary for Medicare Part D coverage would provide leverage to obtain discounts from manufacturers, but it would mean that many patients could no longer access some of their optimal drugs.

As lawmakers seriously consider changes that would produce these negative consequences, industry would do well to voluntarily constrain prices.  Indeed, in the last year, many drug makers have pledged to limit price increases to keep drug spending under control.  Allergan was first, with its “social contract” introduced last September that promised to keep price increases below 10 percent. Since then, Novo Nordisk, AbbVie, and Takeda, have also voluntarily committed to single-digit price increases.

So far, the evidence shows the drug makers are sticking to their promises. Allergan has raised the price of U.S. branded products by an average of 6.7% in 2017, and no drug’s list price has increased by more than single digits.  In contrast, Pfizer, who has made no pricing commitment, has raised the price of many of its drugs by 20%.

If more drug makers brought about meaningful change by committing to voluntary pricing restraints, the industry could prevent the market-distorting consequences of government intervention while helping patients afford the drugs they need.   Moreover, avoiding intrusive government mandates and price controls would preserve drug innovation that has brought life-saving and life-enhancing drugs to millions of Americans.




In a weekend interview with the Washington Post, Donald Trump vowed to force drug companies to negotiate directly with the government on prices in Medicare and Medicaid.  It’s unclear what, if anything, Trump intends for Medicaid; drug makers are already required to sell drugs to Medicaid at the lowest price they negotiate with any other buyer.  For Medicare, Trump didn’t offer any more details about the intended negotiations, but he’s referring to his campaign proposals to allow the Department of Health and Human Services (HHS) to negotiate directly with manufacturers the prices of drugs covered under Medicare Part D.

Such proposals have been around for quite a while.  As soon as the Medicare Modernization Act (MMA) of 2003 was enacted, creating the Medicare Part D prescription drug benefit, many lawmakers began advocating for government negotiation of drug prices. Both Hillary Clinton and Bernie Sanders favored this approach during their campaigns, and the Obama Administration’s proposed budget for fiscal years 2016 and 2017 included a provision that would have allowed the HHS to negotiate prices for a subset of drugs: biologics and certain high-cost prescription drugs.

However, federal law would have to change if there is to be any government negotiation of drug prices under Medicare Part D. Congress explicitly included a “noninterference” clause in the MMA that stipulates that HHS “may not interfere with the negotiations between drug manufacturers and pharmacies and PDP sponsors, and may not require a particular formulary or institute a price structure for the reimbursement of covered part D drugs.”

Most people don’t understand what it means for the government to “negotiate” drug prices and the implications of the various options.  Some proposals would simply eliminate the MMA’s noninterference clause and allow HHS to negotiate prices for a broad set of drugs on behalf of Medicare beneficiaries.  However, the Congressional Budget Office has already concluded that such a plan would have “a negligible effect on federal spending” because it is unlikely that HHS could achieve deeper discounts than the current private Part D plans (there are 746 such plans in 2017).  The private plans are currently able to negotiate significant discounts from drug manufacturers by offering preferred formulary status for their drugs and channeling enrollees to the formulary drugs with lower cost-sharing incentives. In most drug classes, manufacturers compete intensely for formulary status and offer considerable discounts to be included.

The private Part D plans are required to provide only two drugs in each of several drug classes, giving the plans significant bargaining power over manufacturers by threatening to exclude their drugs.  However, in six protected classes (immunosuppressant, anti-cancer, anti-retroviral, antidepressant, antipsychotic and anticonvulsant drugs), private Part D plans must include “all or substantially all” drugs, thereby eliminating their bargaining power and ability to achieve significant discounts.  Although the purpose of the limitation is to prevent plans from cherry-picking customers by denying coverage of certain high cost drugs, giving the private Part D plans more ability to exclude drugs in the protected classes should increase competition among manufacturers for formulary status and, in turn, lower prices.  And it’s important to note that these price reductions would not involve any government negotiation or intervention in Medicare Part D.  However, as discussed below, excluding more drugs in the protected classes would reduce the value of the Part D plans to many patients by limiting access to preferred drugs.

For government negotiation to make any real difference on Medicare drug prices, HHS must have the ability to not only negotiate prices, but also to put some pressure on drug makers to secure price concessions.  This could be achieved by allowing HHS to also establish a formulary, set prices administratively, or take other regulatory actions against manufacturers that don’t offer price reductions.  Setting prices administratively or penalizing manufacturers that don’t offer satisfactory reductions would be tantamount to a price control.  I’ve previously explained that price controls—whether direct or indirect—are a bad idea for prescription drugs for several reasons. Evidence shows that price controls lead to higher initial launch prices for drugs, increased drug prices for consumers with private insurance coverage,  drug shortages in certain markets, and reduced incentives for innovation.

Giving HHS the authority to establish a formulary for Medicare Part D coverage would provide leverage to obtain discounts from manufacturers, but it would produce other negative consequences.  Currently, private Medicare Part D plans cover an average of 85% of the 200 most popular drugs, with some plans covering as much as 93%.  In contrast, the drug benefit offered by the Department of Veterans Affairs (VA), one government program that is able to set its own formulary to achieve leverage over drug companies, covers only 59% of the 200 most popular drugs.  The VA’s ability to exclude drugs from the formulary has generated significant price reductions. Indeed, estimates suggest that if the Medicare Part D formulary was restricted to the VA offerings and obtained similar price reductions, it would save Medicare Part D $510 per beneficiary.  However, the loss of access to so many popular drugs would reduce the value of the Part D plans by $405 per enrollee, greatly narrowing the net gains.

History has shown that consumers don’t like their access to drugs reduced.  In 2014, Medicare proposed to take antidepressants, antipsychotic and immunosuppressant drugs off the protected list, thereby allowing the private Part D plans to reduce offerings of these drugs on the formulary and, in turn, reduce prices.  However, patients and their advocates were outraged at the possibility of losing access to their preferred drugs, and the proposal was quickly withdrawn.

Thus, allowing the government to negotiate prices under Medicare Part D could carry important negative consequences.  Policy-makers must fully understand what it means for government to negotiate directly with drug makers, and what the potential consequences are for price reductions, access to popular drugs, drug innovation, and drug prices for other consumers.

On November 9, pharmaceutical stocks soared as Donald Trump’s election victory eased concerns about government intervention in drug pricing. Shares of Pfizer rose 8.5%, Allergan PLC was up 8%, and biotech Celgene jumped 10.4%. Drug distributors also gained, with McKesson up 6.4% and Express Scripts climbing 3.4%. Throughout the campaign, Clinton had vowed to take on the pharmaceutical industry and proposed various reforms to reign in drug prices, from levying fines on drug companies that imposed unjustified price increases to capping patients’ annual expenditures on drugs. Pharmaceutical stocks had generally underperformed this year as the market, like much of America, awaited a Clinton victory.

In contrast, Trump generally had less to say on the subject of drug pricing, hence the market’s favorable response to his unexpected victory. Yet, as the end of the first post-election month draws near, we are still uncertain whether Trump is friend or foe to the pharmaceutical industry. Trump’s only proposal that directly impacts the industry would allow the government to negotiate the prices of Medicare Part D drugs with drug makers. Although this proposal would likely have little impact on prices because existing Part D plans already negotiate prices with drug makers, there is a risk that this “negotiation” could ultimately lead to price controls imposed on the industry. And as I have previously discussed, price controls—whether direct or indirect—are a bad idea for prescription drugs: they lead to higher initial launch prices for drugs, increased drug prices for consumers with private insurance coverage, drug shortages in certain markets, and reduced incentives for innovation.

Several of Trump’s other health proposals have mixed implications for the industry. For example, a repeal or overhaul of the Affordable Care Act could eliminate the current tax on drug makers and loosen requirements for Medicaid drug rebates and Medicare part D discounts. On the other hand, if repealing the ACA reduces the number of people insured, spending on pharmaceuticals would fall. Similarly, if Trump renegotiates international trade deals, pharmaceutical firms could benefit from stronger markets or longer patent exclusivity rights, or they could suffer if foreign countries abandon trade agreements altogether or retaliate with disadvantageous terms.

Yet, with drug spending up 8.5 percent last year and recent pricing scandals launched by 500+ percentage increases in individual drugs (i.e., Martin Shkreli, Valeant Pharmaceuticals, Mylan), the current debate over drug pricing is unlikely to fade. Even a Republican-led Congress and White House is likely to heed the public outcry and do something about drug prices.

Drug makers would be wise to stave off any government-imposed price restrictions by voluntarily limiting price increases on important drugs. Major pharmaceutical company Allergan has recently done just this by issuing a “social contract with patients” that made several drug pricing commitments to its customers. Among other assurances, Allergan has promised to limit price increases to single-digit percentage increases and no longer engage in the common industry tactic of dramatically increasing prices for branded drugs nearing patent expiry. Last year throughout the pharmaceutical industry, the prices of the most commonly-used brand drugs increased by over 16 percent and, in the last two years before patent expiry, drug makers increased the list prices of drugs by an average of 35 percent. Thus, Allergan’s commitment will produce significant savings over the life of a product, creating hundreds of millions of dollars in savings to health plans, patients, and the health care system.

If Allergan can make this commitment for its entire drug inventory—over 80+ drugs—why haven’t other companies done the same? Similar commitments by other drug makers might be enough to prevent lawmakers from turning to market-distorting reforms, such as price controls, that could end up doing more harm than good for consumers, the pharmaceutical industry, and long-term innovation.
