On August 30, FDA Commissioner Stephen Hahn remarked that the FDA is willing to issue an Emergency Use Authorization (EUA) for a vaccine before the completion of Phase III clinical trials, if the benefits outweigh the risks. EUA authority is granted by the Federal Food, Drug, and Cosmetic Act, allowing the FDA to make unapproved products or unapproved uses of an approved product available during a public health emergency in the absence of a suitable, approved alternative. EUAs have been issued for several drugs and products during the pandemic, including convalescent plasma just last week, remdesivir, and hydroxychloroquine (which has since been revoked). However, unlike drugs that are intended to treat unhealthy patients, vaccines are intended to be deployed to millions of healthy citizens, making safety and efficacy even more paramount. But a rushed EUA can undermine both this safety and efficacy. In a recent Viewpoint in JAMA, PORTAL researchers argue that premature rollout of a vaccine from unprecedented political and economic pressures could result in a major public health misstep. The authors explain the various mechanisms that FDA can utilize to expedite access to a vaccine, but they question whether expedited pathways—particularly, the issuance of an EUA—can negatively impact safety and efficacy by undermining randomized trials and public health measures like social distancing, as well as by missing opportunities for learning about the vaccine’s safety early on. Furthermore, current vaccine hesitancy not only makes it less likely that we will attain needed herd immunity, but it also means that any safety and efficacy issues with an expedited vaccine can undermine the public’s already fragile trust in vaccines. In the midst of one of the worst pandemics in recent history, science and data should come before politics and economics—the FDA can ensure the safety and health of the American public by acting on this data and not succumbing to political and economic pressures. Challenging Patents To Promote Timely Generic Drug Entry: The Second Look Act And Other Options8/31/2020
Liam Bendicksen, Jonathan J. Darrow, and Aaron S. Kesselheim This article was originally published on the Health Affairs Blog. Tackling prescription drug costs remains a top priority for voters. Drug spending in the US is driven both by increasing overall prescription volumes and by high prices for brand-name drugs, which are set freely by manufacturers during patent-protected exclusivity periods that last about 13.5 years after drug approval, on average. One important means of addressing the price component of rising expenditures is to facilitate the market entry of generic drugs after exclusivity periods for brand-name drugs last a reasonable amount of time, since the availability of substitutable generics often leads to rapid and substantial reductions in payer drug spending and patient cost sharing. The latest proposal to encourage timely generic entry is a bill in Congress intended to help efficiently screen out improperly issued drug patents. The Problem: Delays In Generic Entry Caused By Improperly Issued Brand-Name Drug Patents Improperly issued drug patents can and do delay the entry of generic drugs. Indeed, a key strategy of brand-name pharmaceutical manufacturers is to obtain patents not just for active ingredients, but also for peripheral features such as a drug’s coating, formulation, or delivery mechanism. In a previous study, we showed that two highly profitable active ingredients were covered by scores of patents. In some cases, these patents may be obtained after FDA approval of the original drug product (though usually based on patent applications filed prior to drug approval) and extend many years in the future at the time the patent on the active ingredient expires and generics are ready to enter the market. As a result, manufacturers of generics frequently must challenge brand-name drug patents in court to sell their products in the US. To address such improperly issued patents, the 1984 Hatch-Waxman Act created a framework that encouraged manufacturers of generic drugs to challenge brand-name patents in court. In the 1990s and 2000s, generic manufacturers prevailed in challenges of method-of-use and formulation patents between 33 percent and 71 percent of the time. But even an ultimately successful court challenge can entail a protracted legal battle that can delay timely entry of a generic, or even deter entry entirely. Moreover, the Hatch-Waxman Act provides that when patents are listed in the FDA’s “Approved Drug Products with Therapeutic Equivalence Evaluations” (commonly known as the “Orange Book”), a lawsuit initiated within 45 days by a brand-name manufacturer triggers a 30-month stay of FDA approval of the generic product, delaying generic market entry by two-and-a-half years or until the litigation resolves, whichever occurs sooner. The Second Look Act The Second Look at Drug Patents Act of 2020 (The Act), cosponsored by Sens. Patty Murray (D-WA) and John Cornyn (R-TX), would increase awareness of a quicker, more efficient way to challenge brand-name patents, without costly litigation and before they are listed in the Orange Book: inter partes review, an administrative process that Congress created in 2011 as part of the Leahy-Smith America Invents Act that allows the United States Patent and Trademark Office (USPTO) to reevaluate its initial decision to grant a patent. The Second Look Act would amend the Food, Drug, and Cosmetic Act to require sponsors of new drugs to notify the USPTO after submitting patent information to the US Food and Drug Administration (FDA). The USPTO would be required to provide notice of these patents on a new website it would create and maintain and in the USPTO’s Official Gazette, a weekly publication. These notices would help alert interested parties that they could file a petition for inter partes review. Inter partes review can reduce the need to litigate the validity of drug patents in federal court. Compared to litigation, inter partes review has several advantages. Most importantly, it is generally cheaper, quicker, and more efficient than court-adjudicated lawsuits. The Patent Trial and Appeal Board (PTAB), which adjudicates inter partes reviews, is an expert body with more than 200 Administrative Patent Judges that collectively have greater expertise across a wide range of scientific and patent law issues than do most federal district courts. The PTAB uses the evidentiary standard of a “preponderance of the evidence” to determine if a patent is invalid, while courts apply the higher threshold of “clear and convincing evidence” to invalidate a patent, making it easier for a patent challenger to prevail before the PTAB. Any person may initiate an inter partes review at any time, potentially long before a generic drug application is filed. Prior questions about the constitutionality of inter partes review have been resolved, and the process now appears to be on solid legal ground. Of course, inter partes review does not guarantee invalidation of drug patents since, as with court litigation, patents will remain intact if they were validly granted. For example, only 3 percent of active ingredient patents challenged in Hatch-Waxman Act litigation were found invalid or not infringed. But early evidence suggests that inter partes reviews conducted by the PTAB are an effective way to address improperly granted patents, including drug patents. From September 2012 to November 2018, final written decisions issued by the PTAB invalidated 46 percent of claims in Orange Book-listed patents (patents often have multiple “claims” that define the scope of exclusionary rights). The Need For Additional Action While increasing awareness of inter partes review is important, it is crucial to recognize that the Second Look bill does not alter the existing inter partes review process for challenging patents in any way. Furthermore, the patent information provided by the Second Look Act is already in the public domain. Since 1984, federal law has required that drug patent information be provided to the FDA at the time of new drug application submission, and then listed in the Orange Book, which is freely available online. The USPTO already publishes information about new patents in its Official Gazette. Thus, while the Second Look Act might be helpful, more could be done to help generic drugs come to market. For example, patent law currently provides that “a patent shall be presumed valid,” placing the burden on the litigant challenging the patent to prove invalidity by clear and convincing evidence. Rep. Hakeem Jeffries (D-NY) and Rep. Doug Collins (R-GA) have proposed shifting this burden of proof to the brand-name manufacturer. Other policy alternatives include restricting the types of patents that may be listed in the Orange Book. For example, researchers have proposed that policymakers restrict Orange Book listings to a single patent per drug, or to only those patents covering the active ingredient of a drug. Lawmakers could also prohibit late-listed patents, i.e., patents not submitted to the FDA until after the filing a new drug application, unless a patent covers changes that confer additional clinical benefits. However, the listing of patents in the Orange Book was intended to increase transparency and facilitate the filing of patent challenges by generic drug companies, so listing only some patents would frustrate this goal. A better option would be to continue to require that most patents be listed in the Orange Book, but reduce the 30-month stay to a shorter period, such as 18 months. Lawmakers could also limit the stay to a narrower set of patents or eliminate the stay entirely, though this could lead to delayed litigation (and thus delayed generic entry) by removing the incentive for brand-name manufacturers to bring patent challenges within 45 days. Publishing drug patent information in the Official Gazette and a new USPTO website may elevate the visibility of both new drug patents and the inter partes review process, and could encourage generic manufacturers and other interested parties to challenge those patents. But its potential impact, even if enacted, is likely to be limited. Historically, approximately 91 percent of Orange Book-listed patents challenged in inter partes review have also been challenged in court, and 95 percent of Orange Book inter partes review petitions were filed after court litigation began. These figures suggest generic manufacturers are seeking the more challenger-favorable evidentiary standards and other benefits of inter partes review to help clear a path to market entry, but may be less willing to forego the 180-day exclusivity available to first generic patent challengers under the Hatch-Waxman Act (which inter partes review does not provide). While the Second Look Act is a step in the right direction, other ways that lawmakers can address the issue of invalid drug patents delaying generic entry will likely go further towards ensuring a proper balance between drug innovation and access.
Michael S. Sinha Antimicrobial resistance is a very real public health concern, but existing incentives have largely failed to stimulate a robust pipeline of antibiotic development. There are two major types of incentives. "Push incentives" come in the form of early funding of research and development that helps "push" a drug through trials and toward approval. In contrast, "pull incentives" come in the form of lucrative awards for successful drug approvals, intended to "pull" manufacturers toward targeted research and development. Most recently-proposed legislative incentives for antibiotic development largely fall into the latter category. The 21st Century Cures Act's Limited Population Pathway reduced the evidentiary threshold for antibiotic approval. The GAIN Act's Qualified Infectious Disease Product (QIDP) designation doubles the length of Hatch-Waxman exclusivity for qualifying antibiotics (from 5 to 10 years). Another program offers priority review vouchers (PRVs) for drugs to treat tropical diseases, which can be redeemed to expedite FDA review of future drug applications. Finally, wildcard vouchers have been proposed to extend patent exclusivity of marketed drugs in exchange for successful approval of a new antibiotic. A new article by PORTAL researchers in The Journal of Infectious Diseases reviews the latest pull incentives for developing novel antibiotics, which increase reimbursement by the Centers for Medicare and Medicaid Services for inpatient use of new antibiotics. We argue that such financial incentives will—like the other pull incentives described above—continue to favor new antibiotics with limited additional value over existing therapies. We instead recommend incentives that promote the development of better therapies that advance the care of patients with resistant infections.
Rachel E. Barenie Medication nonadherence occurs when patients do not take their medications as prescribed and can be due to numerous factors, such as side effects and high drug costs. Ultimately, nonadherence is tied to poorer patient outcomes and billions of dollars in healthcare spending annually. One possible contributor to nonadherence is the lack of consistency in the appearance of a patient’s medication. In this new study, PORTAL researchers collaborated with the US Food and Drug Administration to better understand patients’ and pharmacists’ preference for and experiences with changes in pill appearance. These included changes in the size, shape, color, and markings of medications. We conducted two independent surveys of practicing pharmacists and patients between January and April of 2016. Patients were 50 years or older and taking medications for one of six chronic diseases. We probed more about how often these changes were occurring, what their (both patients and pharmacists) responses to the changes were, and others. The study found that most patients reported experiencing a change in their pill’s appearance and preferred to be notified about those changes. Fewer than half the patients participating in the survey, however, reported being notified either verbally or with a sticker on their prescription bottle about the change. Of patients who reported a change, 12% reported they either stopped taking or used their medication less frequently because of the change. We found that most pharmacists reported that these changes occurred frequently in their pharmacies and most reported notifying patients when a change occurred.
Jonathan J. Darrow and Jing Luo This blog post originally appeared on the Blog of the Journal of Medical Ethics and can be found here. As government leaders move to relax physical distancing requirements related to severe acute respiratory coronavirus 2 (SARS-CoV-2), a central assumption is that mechanical ventilators will form part of the safety net needed to sustain life in those afflicted with the disease it causes, Covid-19. Ventilators have been described as “crucial” and “essential” “lifesaving devices” that are “desperately needed.” In March, Mayor Bill de Blasio memorably warned that if New York City didn’t get more ventilators “people will die.” By Executive Order, President Trump invoked the Defense Production Act, authorizing the government to compel private industry to produce more of them—at least 30,000 from General Motors alone, at $16,313 each. Overlooked in most news reports was the extent to which ventilators might actually benefit patients with Covid-19. Ventilator Effectiveness Outcomes can vary according to medical circumstances, but historical data provide some insight. The most comprehensive evaluation of prolonged (generally >14 days) mechanical ventilation is a 2015 meta-analysis of 124 observational studies, which found that 57% of patients suffering from various conditions were liberated from mechanical ventilation and 38% were alive at 1 year. Limited evidence is available in patients with coronavirus: in the largest case series in the US, approximately 20% of 5700 hospitalized patients with confirmed SARS-CoV-2 receiving care in NY-area hospitals required mechanical ventilation. Of the 320 patients with an out-of-hospital disposition by study completion, a staggering 88% of those receiving mechanical ventilation died. These preliminary figures could change since 831 patients remained hospitalized and on ventilation when these results were published, but available data suggest that the overall prognosis for patients with Covid-19 who require mechanical ventilation is poor. Even for those who survive, life may not return to normal. The 2015 meta-analysis found that only 19% of all patients were discharged to home (rather than to another facility), and a separate Duke University study of 126 patients reported that only 9% were independent of major functional status limitations at 1 year. A 2019 study of 315 patients receiving prolonged mechanical ventilation at a Chicago-area hospital found that, at 1 year, 60 (19%) could bathe independently, 75 (24%) could dress independently, and 61 (19%) could toilet independently. Expectations of Outcomes by Physicians and Family Members Consistent with the evidence-free discussion of ventilator value, patients and family members have been shown to substantially overestimate the clinical benefits of mechanical ventilation. In a 2009 Duke University study, almost all (93%) family members expected the patient to survive at 1 year, and most (71%) expected high functional status at that time. These inaccurate expectations about prognosis could be the result of the unique circumstances of each patient, such as age and baseline health status, and associated variability in expected outcomes. But the available data offer another possibility: In contrast to family members, fewer than half (43%) of physicians expected patients to be alive at 1 year and almost none (6%) expected them to have high functional status at that time. These data suggest that poor communication may be contributing to inaccurate perceptions of ventilator benefit. The Importance of Disclosure It can be uncomfortable to communicate poor prognoses to patients, and physicians and government officials may prefer to emphasize hope, particularly when there is genuine uncertainty. But ethical ideals of patient autonomy cannot be achieved without disclosing treatment alternatives and their expected benefits and risks, based on the best available evidence. Disclosure is also necessary to enable government officials to make appropriate decisions and benefit from public support when doing so. For example, if ventilator benefit/risk ratios are overestimated, physicians could be pressured to continue a patient on ventilation even when clearly futile, and government officials might under-invest in prevention efforts or, in the longer term, in the development of new drugs or vaccines. Patients and government officials may overestimate benefit in part because the use of mechanical ventilators is supported by a compelling mechanistic rationale: patients need oxygen, and ventilators help patients breathe. But real-world complexities mean simplistic rationales do not always accurately predict outcomes. In some patients with Covid-19, the use of ventilators with higher pressures could actually cause harm, such as by causing over-expansion of alveoli in unaffected regions of the lungs. Ventilator associated pneumonia is also a risk. The issue of effectiveness is not unique to ventilators, and overestimations (or underestimations) of the benefits of drugs, vaccines, social distancing, and other measures could similarly lead to incorrect priorities and misallocation of resources while leaving family members unprepared for what is to come. Although it is desirable for policymakers to actively work to avoid shortages of ventilators or other resources before they occur, the greater the reluctance to engage with the evidence, the less likely important decisions will be evidence-based, leaving officials and health care workers—and ultimately patients—vulnerable to the potential influence of public emotion.

Frank, Jerry Avorn, Aaron S. Kesselheim Editorial Note: Prescription drug spending in the United States continues to increase. A new report from IQVIA titled "Medicine Spending and Affordability in the U.S.: Understanding Patients’ Costs for Medicines" was published earlier this week, providing an updated snapshot of just how high drug costs can be for various stakeholders, including patients. One key finding was that “a record $67 billion was paid out-of-pocket by patients for all prescriptions filled in retail pharmacies in 2019, up from $61 billion in 2015.” The report also notes that patients with higher out-of-pocket costs more frequently abandon their new prescriptions. What do high drug prices buy us, anyway? In April, PORTAL researchers co-authored a Health Affairs blog post which seeks to answer that question. US patients pay far more for the same brand-name drugs than do patients in other affluent countries; these prices are often well out of proportion to the clinical benefits they offer. Recent legislation passed by the House of Representatives would give the federal government the authority to negotiate prices on a modest number of costly brand-name medications, based on factors such as the drug’s effectiveness, the adequacy of alternative treatments, and market size. The Congressional Budget Office has estimated that such negotiation would reduce taxpayer spending on prescription drugs by about $456 billion over 10 years. The pharmaceutical industry has strongly opposed these proposals, making its common objection that they would diminish the incentive to innovate and thereby deprive Americans and the world of access to new cures. The industry’s argument can be summarized as follows: Government should not be involved in limiting what taxpayers and consumers pay for drugs because doing so would lead to less innovation, which would lead to fewer new drugs, which would ultimately put the health of the public at risk. In effect, the industry is administering its own national innovation premium, arguing for its necessity to promote the health of the public. But, having paid that premium for decades now, what do we actually get for it? What do high drug prices buy us? Answering these questions can help provide a more evidence-based assessment of the effects of thinking about the problem in this way. Other Nations Assess the Likely Clinical Impact of Drugs We evaluated all 46 new drugs approved in the United States during the year 2017. Specifically, we considered them in light of the appraisals of their likely clinical impacts conducted by three national health technology assessment agencies outside the US: those in Canada, Germany, and France. The US has no government-funded organization with a mandate or resources to make such assessments for use by patients and their physicians. But a number of industrialized nations systematically assess the therapeutic benefit likely to result from each new medication proposed for inclusion in their health care systems, as part of their standard drug approval and reimbursement processes. These assessments are performed by independent groups of scientists and clinicians based on clinical trials, observational outcome data, consideration of drugs already on the market to treat the same conditions, and the experiences of other nations with a given product. The determinations are made without regard to the drugs’ costs; they are simply an assessment of their benefit to patients, compared to available treatments. Each of the countries whose assessments we used take a slightly different approach: The Canadian Patented Medicine Prices Review Board classifies the incremental benefit of each new drug as conferring one of five levels of improvement: “breakthrough,” “substantial,” “moderate,” “little,” or “no” improvement. In France, the Transparency Committee of the government’s National Authority for Health routinely assesses the medical benefit of recently approved drugs on a four-point scale: “none,” “minor,” “moderate,” or “important.” In Germany, the Institute for Quality and Efficiency in Health Care is an independent nonprofit institute that evaluates the comparative effectiveness of medical interventions. It produces a report that informs the government’s assessment of whether a new drug offers patients “major added benefit,” “considerable added benefit,” “minor added benefit,” “nonquantifiable added benefit” (a category used if, for example, the underlying evidence appears biased or decision uncertainty is high), “no evidence of added benefit,” or less benefit than the appropriate currently available comparator(s). Forty-Six New Drugs For all 46 new molecular entities (NMEs) approved by the Food and Drug Administration in 2017, we reviewed the assessments of each made by these national health care technology assessment bodies (see exhibit 1).
Of the 17 new drugs expected to offer few if any additional benefits to patients above what was available with existing treatments, many are extremely costly. More than two out of every five new medications have not yet been evaluated by any of these three national assessment programs. That could be because the drug has not been approved by the European Medicines Agency or, for drugs such as deflazacort, have been available outside the US for many years. Many of the new products that were assessed (such as glecaprevir-pibrentasvir for vital hepatitis infection, or semaglutide for type 2 diabetes) are highly effective but represent second- or third-in-class products that offer little clinical benefit over their predecessors in the class. It is reasonable to offer some incentives for such products, to offer options for patients who cannot tolerate the first-line product, or to encourage competition, even though price competition among comparable brand-name products in the US has historically been quite limited. Together, this information raises the question of how effectively the existing “innovation premium” imposed by the pharmaceutical industry is yielding gains for patients or the public’s health. Furthermore, if the government negotiated for prices based on a drug’s real advantage over existing products, it could provide a better incentive for more useful innovation as well as improve the affordability of prescription drugs. Would such a policy lead to the development of more drugs that truly advance patients’ health, as well as address the growing problem of the affordability of new medications? To fairly answer these questions, it is time to think about what the US innovation premium buys. Exhibit 1: Drugs approved in the US in 2017 and the outcomes of their clinical reviews in Germany, France, and Canada Source: Authors’ compilation from corresponding agencies. Notes: * Determinations different for indicated population subgroups for brodalumab (for patients with inadequate response to systemic therapy or contraindicated/intolerant to it, in light of the “assumptions were made for both approaches in order to take into account the very high proportion of values to be replaced”) and emicizumab (for patients with bypassing agent “due to uncertainties regarding the appropriateness of the treatment regimens used”). All assessments are for indications at the time of European approval/market entry.
Liam Bendicksen This blog post originally appeared on the Incidental Economist blog and can be found here. Despite overwhelming agreement among voters that the cost of prescription drugs is too high, Congress has yet to pass substantive legislation in recent years to tackle drug prices. In the absence of federal action, New York lawmakers stepped up to the task in 2017, establishing a drug spending cap in the state’s Medicaid program. Setting an annual limit on the state Medicaid program’s prescription drug spending, however, meant that the legislature also needed to give Medicaid officials a way to keep costs down. So how has New York gone about cutting excess drug spending? The answer is that the New York legislature gave officials the power to systematically limit the price of high-cost prescription drugs to their therapeutic value. More specifically, the state authorized its Medicaid Drug Utilization Review Board to conduct reviews of the value of expensive drugs when officials project that the program’s annual drug spending cap will be exceeded. After the board determines a value-based price for a drug, the state then negotiates additional rebates with the drug’s manufacturer. To compel manufacturers to come to the table and concede supplemental rebates, the New York Medicaid program may implement a number of strategies intended to lower manufacturers’ profits if they don’t comply. These bargaining chips include instituting prior authorization requirements, directing Medicaid managed care organizations to remove the drug from their formularies, and limiting reimbursement for provider-administered therapies that are billed under the medical benefit. Under the terms of the Medicaid Drug Rebate Program, however, New York may not remove a drug from its Medicaid formulary. This means that using a state-run approval process, beneficiaries can still receive Medicaid coverage for drugs that are not on their managed care plan’s formulary. Though the New York Medicaid program was the first public payer in the US to limit reimbursement for prescription drugs based on therapeutic value, this practice is common in many European countries. The New York Medicaid Drug Utilization Review Board utilizes many of the same tools used in health technology assessment in Europe, including quality-adjusted life-years (QALYs) and reference pricing, though in a more limited capacity. To date, the New York Medicaid Drug Utilization Review Board has completed three pricing reviews. In these reviews, the board determined target supplemental rebate amounts for lumacaftor/ivacaftor (Orkambi), infliximab (Remicade), and nusinersen (Spinraza). Following the board’s reviews of lumacaftor/ivacaftor and infliximab, the New York Department of Health was able to reach confidential supplemental rebate agreements for both drugs with their respective manufacturers. In the case of nusinersen, the board only recently announced the completion of their review at a public meeting on July 23, 2020. Though negotiations between New York officials and the drug’s manufacturer Biogen will be kept confidential, the state’s prospects for securing additional rebates seem promising in light of the drug’s billing under the medical benefit in Medicaid. This is the case because of the board’s ability to direct Medicaid managed care organizations to reduce reimbursement for provider-administered drugs billed under the medical benefit, which includes nusinersen, if manufacturers refuse to concede adequate supplemental rebates. It’s possible that this same leverage helped prompt Janssen Pharmaceuticals, the manufacturer of infliximab, to agree to pay additional rebates to New York after the board’s review of the drug last year. Efforts to conduct assessments of the value of drugs and other medical goods and services in the public sector in the US have been met with fiery political opposition. After all, who could forget Sarah Palin’s infamous and wildly inaccurate claims about how the Affordable Care Act would create “death panels”? More than a decade later, the consequences of rejecting cost-effectiveness research are starting to come into focus. Today, rising brand-name prescription drug prices (and increasingly-prevalent high-deductible health plans) pose a threat to Americans’ financial security and to the health of our communities. Political controversies notwithstanding, using cost-effectiveness research and analyses to pay for high-value prescription drugs can help US patients afford the drugs they need as prices continue to rise. While value is difficult to measure or even define in health care, working through those difficult questions is well worth the reward of maximizing patient health and lowering costs. Value-based pricing frameworks, such as those used by the Institute for Clinical and Economic Review, are valuable tools that can help policymakers rationalize the way we pay for pharmaceuticals. Taxpayer dollars have bankrolled the pharmaceutical industry’s inflated bottom line for far too long. To protect Americans’ health and financial security, lawmakers across the country should follow the trailblazing example of the New York Medicaid Drug Utilization Review Board and join in the pursuit of systematically-achieved, value-based drug prices in the US.
Neeraj Patel Today, PORTAL Director Aaron Kesselheim testified as a witness before the Subcommittee on Health of the House Committee on Energy and Commerce during a hearing on "Improving Access to Care: Legislation to Reauthorize Key Public Health Programs." Dr. Kesselheim urged Congress against passing H.R. 4439, which would permanently reauthorize the rare pediatric disease priority review voucher program. He outlined shortfalls of the program and pointed to alternative approaches that Congress can take to improve availability and access to drugs for rare pediatric diseases. In describing the shortfalls of the program, Dr. Kesselheim's testimony references a February 2019 Health Affairs study by PORTAL researchers and colleagues. He writes, "My colleagues and I at Harvard Medical School showed no increases after 2012 in the rate of new drugs entering clinical trials for rare pediatric diseases when compared to drugs for rare adult diseases, which did not earn a voucher." Dr. Kesselheim also discussed the overstated and diminishing economic value of the voucher incentive, the potentially dangerous public health risks associated with accelerated review of these types of products, and strains that the program has put on the FDA. Moreover, Dr. Kesselheim outlined alternative approaches that can be taken to increase development of and access to drugs for rare pediatric disease: "For example, Congress could provide greater up-front public funding or tax credits for research into rare pediatric diseases. Another approach would be to provide greater support for late-stage development through public-private partnerships with non-profit organizations. Naturally, such partnerships should include guarantees about affordable access to the rare pediatric disease drugs that emerge because of the public’s involvement in reducing the risks and costs of research and development." Dr. Kesselheim's full written testimony can be found here. Full video of the hearing is available below. Phebe Hong The patent-based pharmaceutical innovation system in the United States is often criticized on two grounds. First, it does not incentivize the development of drugs with the greatest impact on patient or public health, instead encouraging private investment in drugs that are likely to generate the greatest revenues. Second, it leads to drug prices that patients and health care systems cannot afford. One well-known example of the shortcomings in the current innovation model is the direct-acting antiviral Solvadi, a drug approved by the FDA in 2013 that cures chronic hepatitis C virus infection. Payers like Medicaid were unable to offer it to all qualifying patients because of the drug’s high cost. Although prices of direct-acting antivirals have declined in recent years due to competition, they remain high, with many patients still unable to access treatment. A new study by researchers at PORTAL takes a closer look at new, transformative models for promoting drug innovation and access. Specifically, the study analyzes three different models: delinkage, public manufacturing, and public private partnerships. All three models offer greater innovation, transparency, efficiency, and affordability. Delinkage. Delinkage models involve payments for drug innovation based on public health value rather than patient use. Instead of rewarding innovators with market exclusivity, innovators are rewarded directly with so-called “innovation inducement prizes” or “market entry rewards.” Delinkage systems reduce or eliminate an innovator’s reliance on sales to recuperate research and development investments and earn profits. The study found that although delinkage has been proposed as a strategy to tackle antimicrobial resistance, to date there has been no large-scale implementation of delinkage models for drug development. Public Manufacturing. Public manufacturing refers to the development and production of drugs by a government or nonprofit entity. The most prominent example is Civica Rx, which launched in September 2018 as a nonprofit devoted to bringing stability to the hospital supply chain by manufacturing common generic drugs. In addition, the Affordable Drug Manufacturing Act, first proposed by Senator Elizabeth Warren in 2018 and re-introduced in January 2020, is a proposal for a government authority to manufacture generic drugs. The study recommends that in order to protect against industry capture, governance of public manufacturing entities must be designed with clear objectives, transparency, and public participation in mind. Public Private Partnership. Finally, public private partnerships involve publicly-funded organizations working closely with for-profit partners on drug development. The leading example is the Biomedical Advanced Research and Development Authority, a federal body created in 2006 to prepare society with biodefense and pandemic tools. Although some partnerships, such as the Drugs for Neglected Diseases Initiative, have been successful in developing and commercializing novel treatments, most partnerships continue to operate within the existing system that allows companies to retain patent-based monopolies, which can lead to high prices and suboptimal access. The study suggests that reforms related to intellectual property rights associated with such partnerships are necessary to prevent this outcome. Each of these models exhibits promise in promoting prescription drug innovation and access. The study recommends further research to better understand these three models, with the goal of eventually creating an alternative system to the current patent-based model of drug development.
