Examining Pricing And Availability For Neglected Tropical Disease Therapies In The Us, Maple Goh, Kevin Outterson, Aaron S. Kesselheim

Faculty Scholarship

Background

Neglected tropical diseases primarily affect vulnerable populations in low-resource settings worldwide. In the US, neglected tropical diseases such as Chagas, soil-transmitted helminthiases, and other infections historically impacted immigrants but are increasingly relevant for US residents with climate change. We examined the pricing, prescribing rates, and supply of therapies used to treat neglected tropical diseases in the US and their implications for accessibility and patient care. Methods

A retrospective analysis of prescription rates, wholesale acquisition costs, and shortages was conducted for 11 treatment products from 2019 to 2024, aggregating data from Symphony Metys, First Databank, NAVLIN, Red Book, and the …

Public Patent Powers, Laura E. Dolbow

Michigan Law Review

Congress has created multiple structures for agencies to control how patents are used, but that institutional design choice has received little academic attention. This Article provides the first comprehensive survey of existing laws that expressly authorize agencies to control patents. I locate 113 express conditions across 68 laws that expressly authorize executive actors to make some form of decision about patents. These powers, which I refer to as “public patent powers,” allow the government to use patented inventions, to obtain patents, to authorize third parties to use patented inventions, and to regulate how patents are used. Agencies have used many …

The Future Of Healthcare Is Generic: Expanding Hatch-Waxman To Equitably Regulate The Healthcare Products Industry, George Encarnacion Jr.

DePaul Journal of Health Care Law

This article serves to address the statutory disconnect in the healthcare industry regarding generic products. There has been marked success in the generics market pertaining to pharmaceutical drugs, but the same cannot be said for medical devices and, in more recent times, biosimilars. The end result for consumers is higher product prices, limited access of care, and a more burdensome healthcare system. This article explores the statutory history of drug and medical device approval and production. It also explores differences between modern regulation of generic drugs and generic medical devices, focusing on key issues of FDA approval, consumer safety and …

Ignoring Drug Trademarks, Erika Lietzan

Faculty Publications

If you walk into a pharmacy with a prescription for Merck’s ZOCOR, which contains simvastatin, the pharmacist will probably give you a product containing simvastatin made by another company. The pharmacist will dispense a “generic” simvastatin product. State generic substitution laws, passed in the 1970s to help the government save money by switching patients to cheaper generic drugs, either permit or require this substitution. But drug brand names -- such as ZOCOR -- are trademarks. Like other trademarks, they distinguish goods in the market from others, and they signal the source of the goods. These state laws essentially treat the …

The "Evergreening" Metaphor In Intellectual Property Scholarship, Erika Lietzan

Faculty Publications

This article is a plea for changes in the scholarly dialogue about "evergreening" by drug companies. Allegations that drug companies engage in "evergreening" are pervasive in legal scholarship, economic scholarship, medical and health policy scholarship, and policy writing, and they have prompted significant policymaking proposals. This Article was motivated by concern that the metaphor has not been fully explained and that policymaking in response might therefore be premature. It canvasses and assesses the scholarly literature-more than 300 articles discussing or mentioning "evergreening." It catalogues the definitions, the examples, and the empirical studies. Scholars use the term when describing certain actions …

Paper Promises For Drug Innovation, Erika Lietzan

Faculty Publications

Innovation does not stop when a new medicine is launched. Development of new uses for already approved drugs, in particular, can make profound contributions to the public health. Whether a new use is suspected during the initial premarket trials, identified through focused research after approval, or discovered serendipitously by physicians treating patients, however, it requires extensive clinical testing before it can be approved by FDA. This testing takes time and money — three to five years on average, and as much as $300 million. This Article considers the incentives that federal law offers to companies to make this investment: patent …

Improving Generic Drug Approval At The Fda, Kathleen Craddock

Michigan Journal of Environmental & Administrative Law

Generic drugs are the store-brand cereal of the drug world. While they lack the vibrant colors of and exciting commercials behind name brands, generics are still effective. Most importantly, for some people, they make the difference between accessing essential treatment and going without. Getting generics to market as quickly as possible means fewer people will cut pills in half or skip doses to save money, which also saves billions of dollars across the U.S. health system. Because a new generic does not offer lifesaving changes for people with rare or complicated diseases, generics lack the “cultural capture of rhetoric about …

A Solution In Search Of A Problem At The Biologics Frontier, Erika Lietzan

Faculty Publications

This short paper comments on Professor Carrier's new article, Biologics: The New Antitrust Frontier. His article makes a profound initial contribution to a new area of scholarship, based on a large body of prior work considering antitrust issues relating to small molecule drugs. But Professor Carrier’s article, like my own forthcoming piece on innovation and competition in the biologics marketplace, is inherently speculative. We are making our best judgments about the nature of a still emerging marketplace and likely conduct in that marketplace, based on our understandings of a new regulatory framework that is itself still emerging, the broader legal …

The History And Political Economy Of The Hatch-Waxman Amendments, Erika Lietzan

Faculty Publications

Reform of the Hatch–Waxman generic drug framework is in the air. Scholars, consumer advocacy groups, regulated industry, and policymakers are engaged in heated debate about perceived shortcomings in the scheme, flaws, and unexpected loopholes. Changes in how the U.S. Food and Drug Administration (FDA) implements the law, as well as changes to the law itself, are under serious consideration. These policymaking discussions take place against a backdrop of shared assumptions about the origins and nature of the original Hatch–Waxman legislation — assumptions that this Article claims are wrong. Convention wisdom holds that the Hatch–Waxman legislation was a delicate compromise privately …

Wiggle Room: Problems And Virtues Of The Inwood Standard, Rian C. Dawson

Indiana Law Journal

This Note investigates the origins of Inwood that led to the slim opinion with wide influence. It argues that the very vagueness for which scholars and practitioners have decried Inwood is the case's greatest virtue: Inwood provides a flexible standard that has allowed the common law to evolve and address new business models. Part I discusses the origins of contributory infringement in intellectual property. Part II investigates the Inwood case and the climate of trademark law at the time Inwood was litigated. It also dissects the majority opinion and Justice White's concurrance. Part III examines the Inwood standard's evolution at …

Deterring Innovation: New York V. Actavis And The Duty To Subsidize Competitors' Market Entry, Joanna Shepherd

Faculty Articles

This Article examines a relatively new business strategy in the pharmaceutical market -- "product hopping" or "product replacement" -- in which brand pharmaceutical companies shift their marketing efforts from a drug nearing the end of its patent period to a new, substitute drug with a longer patent life. In July 2015, the Second Circuit issued an opinion in the first appellate case addressing pharmaceutical product replacement, New York ex rel. Schneiderman v. Actavis PLC. This Article explains that product replacement is the predictable business response to the incentives created by patent law and state substitution laws, and withdrawing an …

An Administrative Meter Maid: Using Inter Partes Review And Post-Grant Review To Curb Exclusivity Parking Via The "Failure To Market" Provision Of The Hatch-Waxman Act, Brian T. Apel

Michigan Law Review

Congress created the unique Hatch-Waxman framework in 1984 to increase the availability of low-cost generic drugs while preserving patent incentives for new drug development. The Hatch-Waxman Act rewards generic drug companies that successfully challenge a pharmaceutical patent: 180 days of market exclusivity before any other generic firm can enter the market. When a generic firm obtains this reward, sometimes drug developers agree to pay generic firms to delay entering the market. These pay-for-delay agreements give rise to exclusivity parking and run counter to congressional intent by delaying full generic drug competition. The Medicare Prescription Drug, Improvement, and Modernization Act created …

Patent Punting: How Fda And Antitrust Courts Undermine The Hatch-Waxman Act To Avoid Dealing With Patents, Rebecca S. Eisenberg, Daniel A. Crane

Michigan Telecommunications & Technology Law Review

Under the Hatch-Waxman Act, patent law and FDA regulation work together to determine the timing of generic entry in the market for drugs. But FDA has sought to avoid any responsibility for reading patents, insisting that its role in administering the patent provisions of the Hatch-Waxman Act is purely ministerial. This gap in regulatory oversight has allowed innovators to use irrelevant patents to defer generic competition. Meanwhile, patent litigation has set the stage for anticompetitive settlements rather than adjudication of the patent issues in the courts. As these settlements have provoked antitrust litigation, antitrust courts have proven no more willing …

Pay-For-Delay Settlements In The Wake Of Actavis, Michael L. Fialkoff

Michigan Telecommunications & Technology Law Review

“Pay-for-delay” settlements, also known as reverse payments, arise when a generic manufacturer pursues FDA approval of a generic version of a brand-name drug. If a patent protects the brand-name drug, the generic manufacturer has the option of contesting the validity of the patent or arguing that its product does not infringe the patent covering the brand-name drug. If the generic manufacturer prevails on either of these claims, the FDA will approve its generic version for sale. Approval of a generic version of a brand-name drug reduces the profitability of the brand-name drug by forcing the brand-name manufacturer to price its …

Actavis, The Reverse Payment Fallacy, And The Continuing Need For Regulatory Solutions, Daniel A. Crane

Articles

The Actavis decision punted more than it decided. Although narrowing the range of possible outcomes by rejecting the legal rules at the extremes and opting for a rule of reason middle ground, the opinion failed to grapple with the most challenging issues of regulatory policy raised by pharmaceutical patent settlements. In particular, it failed to clearly delineate the social costs of permitting and disallowing patent settlements, avoided grappling with the crucial issues of patent validity and infringement, and erroneously focused on “reverse payments” as a distinctive antitrust problem when equally or more anticompetitive settlements can be crafted without reverse payments. …

The Paradox Of Legal Equivalents And Scientific Equivalence: Reconciling Patent Law's Doctrine Of Equivalents With The Fda's Bioequivalence Requirement, Janet Freilich

Faculty Scholarship

Contrary to popular perception, generic drugs often enter the market before the patents covering their brand name counterparts have expired by making slight changes to the drug to avoid the brand name patent. These generics face a paradox: the U.S. Food and Drug Administration (FDA) requires that the generic "not show a significant difference" from the reference product, while patent law requires that the generic have "substantial differences" as compared to the reference product. The generic must be bioequivalent, but not legally equivalent, to the brand name drug. This paradox occurs frequently in the courts but has never been discussed …

Patent Infringement In The Context Of Follow-On Biologics, Janet Freilich

Faculty Scholarship

This Article fills a gap in the literature by conducting a comprehensive analysis of patent infringement in the context of follow-on biologics. Patent infringement is an important topic because, like small molecule generic drugs, follow-on biologics are likely to begin their life facing infringement suits. Because it is tremendously expensive to develop a follow-on biologic, it is vital that there be consistency in how they are treated in the courts once the inevitable patent infringement suits arrive. If follow-on biologics companies cannot predict how their product will be received in court, they may decide it is not worth the risk …

Patents V. Statutory Exclusivities In Biological Pharmaceuticals - Do We Really Need Both, Yaniv Heled

Michigan Telecommunications & Technology Law Review

Over the past decade or so, the United States has been the arena of a boisterous debate regarding the creation of a new regulatory framework for the approval of generic versions of biologics-based pharmaceutical products (also known as "biological products" and "biologics")--an important and increasingly growing class of drugs. The basic purpose of such a framework is to create a fast and less-costly route to FDA approval for biologics that would be similar or identical to already-approved biological products--typically ones that are sold on the market at monopoly rates--thereby allowing cheaper versions of such medicines to enter the market. One …

Use Patents, Carve-Outs, And Incentives — A New Battle In The Drug-Patent Wars, Arti K. Rai

Faculty Scholarship

The Hatch-Waxman Act of 1984 aims to strike a balance between the innovation incentives provided by patents and the greater consumer access provided by low-cost generic drugs. The legislation, which relies in part on an explicit link between the FDA drug approval process and the U.S. patent system, has been controversial, particularly because of the ways in which firms producing brand-name drugs have exploited that link to delay market entry of generics as long as possible. Voluminous scholarship has focused on so-called "pay-for-delay" settlements of patent litigation between brand name and generic firms.

In contrast, this Perspective uses the lens …

Pliva V. Mensing And Its Implications, Brian Wolfman, Dena Feldman

Georgetown Law Faculty Publications and Other Works

The U.S. Supreme Court ruling in PLIVA Inc. v. Mensing will immunize generic drug manufacturers facing failure-to-warn claims from state-law liability, and may also have implications for preemption jurisprudence more generally, says attorney Brian Wolfman and co-author Dena Feldman in this BNA Insight. The authors analyze the ruling, and offer their views on the questions that PLIVA raises about the ongoing vitality of the presumption against preemption, the standard for determining ‘‘impossibility’’ preemption, and the propriety of deference to an agency’s views on preemption.

Pharmaceutical Patent Litigation Settlements: Balancing Patent & Antitrust Policy Through Institutional Choice, Timothy A. Cook

Michigan Telecommunications & Technology Law Review

Should a branded pharmaceutical company be allowed to pay a generic competitor to stay out of the market for a drug? Antitrust policy implies that such a deal should be prohibited, but the answer becomes less clear when the transaction is packaged as a patent-litigation settlement. Since Congress passed the Hatch-Waxman Act, which encourages generic manufacturers to challenge pharmaceutical patent validity, settlements of this kind have been on the rise. Congress, the Department of Justice, and the Federal Trade Commission have condemned these agreements as anticompetitive and costly to American consumers, but none of these bodies has been able to …

Teva V. Eisai: What's The Real Controversy, Grace Wang

Michigan Telecommunications & Technology Law Review

This Note examines the changing role of declaratory judgment actions in challenging patents upon generic entry and evaluates alternative regulatory schemes to the FDA's current system of patent enforcement in the drug approval setting. Part I reviews the Federal Circuit's recent decisions regarding generic drug entry, focusing on how the courts justify declaratory judgments in the current system and when a "controversy" exists to create Article III jurisdiction. Part II examines the complex system of regulating generic drug entry and how attempts to stop the exploitation of loopholes have resulted in a patchwork of regulation by various parties. It challenges …

Provigil: A Commentary, Daniel A. Crane

Articles

Michael Carrier's case study on Provigil' offers new support for the view that Big Pharma is to blame for stymieing competition, retarding innovation, and inflating prices in the drug industry. Carrier argues that Cephalon was able to thwart generic entry by a combination of anticompetitive strategies. It entered into a reverse payment settlement agreement with generics seeking to enter the market. These settlements purported to allow generic entry before the expiration of the patent period, but, according to Carrier, the promise of early entry was negated by the second prong of Cephalon's anticompetitive strategy. During the time that it had …

Allocating Liability For Deficient Warnings On Generic Drugs: A Prescription For Change, Sarah C. Duncan

Vanderbilt Journal of Entertainment & Technology Law

Brand-name pharmaceutical companies create pioneer drugs that cure diseases around the world. However, because research and development costs are very high, brand-name drugs are expensive. In response to escalating costs, Congress enacted the Drug Price Competition and Patent Term Restoration Act of 1984 ("Hatch-Waxman Act") to promote generic competition. As generics become more prominent in the pharmaceutical marketplace, individuals injured by generic drugs are suing the manufacturers with more frequency. The cases often turn on which company should bear the liability for failing to warn--the brand-name manufacturer or the generic drug maker. Although the injured person took the generic drug, …

Generic Preemption: Applying Conflict Preemption After Wyeth V. Levine, Hannah B. Murray

Michigan Telecommunications & Technology Law Review

If a generic manufacturer does not have control over its safety warnings, can it comply with the obligations posed by state tort liability? State failure-to-warn actions evaluate whether a product manufacturer has met its obligation to warn consumers about known dangers associated with its product. In essence, if a manufacturer knows about a potentially dangerous outcome, it has a duty to warn its consumers. If the generic manufacturer can comply with a state duty to warn only by changing a label that the FDA will not allow it to change, it becomes impossible for the corporation to meet both requirements. …

A New History And Discussion Of 180-Day Exclusivity, Erika Lietzan, David E. Korn, Shaw W. Scott

Faculty Publications

This is the third in a series of articles on 180-day exclusivity. The first article traced the history of 180-day exclusivity from 1984 through its amendment in 2003 and court cases in 2004. A second article, published by two of the authors in 2007, updated the earlier piece through the end of 2006 but was arranged by issue rather than in a chronology. This article, which includes a third author, provides a comprehensive resource on 180-day exclusivity for old abbreviated new drug applications (ANDAs) (but less detail in some places where the 2007 article may be referenced) and focuses more …

Pharma's Nonobvious Problem, Rebecca S. Eisenberg

Articles

This Article considers the effect of the recent decision of the U.S. Supreme Court in KSR International Co. v. Teleflex, Inc. on the nonobviousness standard for patentability as applied to pharmaceutical patents. By calling for an expansive and flexible analysis and disapproving of the use of rigid formulas in evaluating an invention for obviousness, KSR may appear to make it easier for generic competitors to challenge the validity of drug patents. But an examination of the Federal Circuit's nonobviousness jurisprudence in the context of such challenges reveals that the Federal Circuit has been employing all along the sort of flexible …
