Inter Partes Review: A Questionable Item in the Generic’s Tool Kit

Will Orlady, MJLST Lead Articles Editor

In 1984, Congress enacted the Drug Price Competition and Patent Term Restoration Act (Hatch-Waxman). Since then, pioneer pharmaceutical manufacturers and their generic counterparts have resolved patent disputes in federal district court under the Hatch-Waxman patent dispute framework. This framework is admittedly complex. But it forces interested parties to engage with Hatch-Waxman, mandating compliance with congressionally determined policy decisions regarding pharmaceutical exclusivity. Hatch-Waxman’s patent dispute framework was part of the larger bill, crafted to balance the interests of pioneer and generic drug manufacturers. Congress enacted the law to address two (apparently competing) goals: (1) to encourage innovation in pharmaceutical research and development and (2) to help generic drugs reach the market more quickly. The tension between these goals merits further discussion.

Before Hatch-Waxman, concerns grew that drug prices were too high and that access to certain treatments was too limited. Thus, there was both need and substantial demand for cheaper, generic drugs. On the other hand, pioneer drug manufacturers complained of inadequate market exclusivity following FDA’s New Drug Application (NDA) process. Put simply, pioneer companies spent (and continue to spend to this day) approximately $1 Billion brining a new drug to market. On top of the money, pioneer manufactures potentially spend several years of their drugs’ valuable patent terms going through the NDA process. Thus, pioneer companies noted that recouping R&D and regulatory expenses was not feasible given the “short” market exclusivity period.

Hatch-Waxman was a carefully wrought legislative compromise. It granted pioneers a patent term extension based on the length of FDA’s regulatory review, non-patent market exclusivity provisions, a mechanism for increasing the public notice of patents and patent challenges, and an automatic injunction forbidding FDA approval of a generic drug in certain circumstances. The generic manufacturers got, among other things, the Abbreviated New Drug Application (ANDA), making the regulatory process for generic drugs less onerous. To be sure, Hatch-Waxman is not without its critics, and its nuances are immense. But it is important to remember that the act represents a careful Congressional balancing of industry and public interests. Hatch-Waxman’s patent dispute resolution mechanism squarely fits within this compromise.

Enter the America Invents Act (AIA) of 2011. Of note, the AIA revised certain post-grant opposition procedures. Specifically, the law expanded the importance of inter partes review (IPR). IPR is a process by which a third party may have a patent reexamined by the patent office to verify that the office validly issued the patent. Since the AIA’s enactment, IPR has become immensely popular. Why is this? IPR offers a potential alternative to district court litigation. It provides advantageous invalidation standards—e.g. the “broadest reasonable interpretation” during claim construction. Further, IPR allows patent challenges with relatively limited discovery, cutting both the time and cost of district court patent litigation. Finally, IPR petitioners have been enormously successful in invalidating many of the patents challenged to date.

Needless to say, IPR frightens patentees holding rights to valuable patents. Can you see where I’m going here? Are particular Congressional mandates and policy determinations on a collision course?

The post-AIA surge of IPR proceedings has pioneer pharmaceutical manufacturers worried—rightly so. Generic manufacturers are already petitioning the U.S. Patent and Trademark Office (PTO) for IPR of patents protecting various pharmaceutical and biologic products. Given the aforementioned advantages of IPR, this shouldn’t come as a surprise, but that is not to say that it is not remarkable. Generic manufacturers could be leveraging the advantages of IPR to force pioneer drug manufacturers to settle patent disputes out of district court. Or, of more consequence, they could be using IPR to skirt the patent dispute frameworks required by Hatch-Waxman and the BPCIA (for biologics).

Indeed, if pioneer pharmaceutical manufacturers hold patents allowing for market exclusivity, the patents should be validly issued. It is, however, simultaneously important to remember that Congress has treated drug and biologic patents differently since, at the very least, 1984. Pharmaceutical patents are remarkable in at least three key ways. First, patents on commercially successful drugs are extraordinarily valuable. Congress (at least ostensibly) allows this because of the enormous regulatory barriers to entry. In other words, it’s a trade. FDA imposes supra-burdensome regulatory costs to ensure new drugs are safe and effective. Consequently, Congress allows pioneer drug manufacturers to unilaterally exploit the market to recoup losses, and make money. Second, pharmaceutical patents read on particles of matter that are harnessed to treat disease and save lives. This creates a unique demand. And third, pharmaceutical patents read on products which require sensational development costs, including the time and money required for regulatory approval.

Does this mean pharmaceutical patents should be treated differently, or made exempt from IPR? The answer is not so simple. But legislators, scholars, and practitioners should consider whether IPR is having unintended consequences within the pharmaceutical industry. Just as a quick example: Did Congress truly intend for the AIA’s IPR to be a way around Hatch-Waxman or the BPCIA? And even if it did, does it make sense to put enormously valuable patents at the mercy of an overburdened administrative agency? As I said, the answers don’t come readily. It’s a policy debate that needs to happen. Until it does, I think it unwise to abandon previously established Congressional compromises—i.e. Hatch-Waxman—for a hasty change to our patent system.


A Story to Warm Your Iron-Rich Hemoglobin

Becky Huting, MJLST Articles Editor

While recently home in Chicago on spring break, I offered to make my dad a spinach-packed smoothie. My dad (a good sport) agreed, but asked me to make it light on the spinach as he understood men at his age (60) should be taking it easy on the iron intake. I had heard this principle before, and knew that men’s and women’s vitamin supplements were different in part due to the additional iron needs of women. My dad was right about one thing: he needs a lot less iron than me. His recommended dietary allowance for iron is 8 mg/day whereas mine is a lofty 18 mg/day. In actuality, men rarely suffer from iron deficiency so supplements are usually unnecessary, and in fact too much iron can indeed be harmful. There are possible links with excessive iron consumption to diabetes as well as neurodegenerative disease.

But where his concerns are unfounded are in the nutritional numbers. One cup of uncooked spinach contains only .8 mg of iron. That is only one-tenth of his daily iron needs. Three ounces of ground beef containing 15% fat contains 2.2 mg of iron. What about his daily serving of canned, drained clams, you ask? Fine, you have me there: if my father actually consumed such item, he’d have gone over at 23.8 mg of iron. It is very hard though for a human to overdose on iron from food, because an adult body has systems in place to regulate the amount of iron it absorbs. In short, my dad need not be concerned about spinach in his smoothie, except for reasons of palatability.

So given the different nutritional needs of men, women, and also children, what entity is telling consumers whether a vitamin is for them by way of labels? The Food and Drug Administration (FDA) relinquished that duty back in October of 1994, when the Dietary Supplement Health and Education Act (DSHEA) was passed. This law created a new regulatory framework for the safety and labeling of dietary supplement that places the responsibility on the product manufacturers rather than the FDA. The DSHEA was a response to lobbying by health food companies to vote down several bills that would have had the effect of increasing the FDA’s powers over supplement labeling. Celebrities even got involved. In one commercial, Mel Gibson portrayed a citizen being raided and arrested by FDA agents for possessing a bottle of Vitamin C.

This mentality that too much government oversight is a bad thing is a popular ideal. After all, it’s only a vitamin. Perhaps a label signifying use by pregnant and nursing moms is enough, but consider the 60-year-old guy grabbing this supplement in haste. He is now getting 27 mg iron per day from the vitamin alone, perfect for a pregnant woman, but over 3X his nutritional needs. Are a few words on a label enough to signify safety to a consumer? Certainly there is an argument that too much information will lead to a cluttered, confused label. So where do you come down, bring the FDA back in or leave it to the companies? And do you feel like a green smoothie? I promise you the banana masks the spinach flavor.


Scientific Responsibility: Why Lawyers are Imperative in Scientifically Informed Neuro-ethics

Thomas Hale-Kupiec, MJLST Staff Member

In Volume 11, Issue 1 of the Minnesota Journal of Law, Science, & Technology, Eagleman, et al. conclude that “the neuroscientific community should continue to develop rehabilitative strategies so that the legal community can take advantage of those strategies for a rational, customized approach” in Why Neuroscience Matters for Rational Drug Policy. Though perhaps this assertion is valid in the context of Drug Addiction, I believe it is necessary to limit this assertion to solely rehabilitative drug addiction studies; to allow a further extension of this conclusion would be sociologically detrimental. I postulate that beyond ideas of who we define as a “Neuroscientist,” legal experts need to be at the forefront of this debate in order to better define and formulate ideas of “rehabilitation.”

In a related reflection entitled ‘Smart Drugs’: Do they work? Are they ethical? Will they be legal?, researcher Stephen Rose poses a number of ethical and neurological impacts of mind enhancing substances. The author posits an interesting question: what is “normal” for a brain? If someone undergoes pharmacological manipulation, what should the standard be for “abnormal?” For instance, Rose poses that some substances could be used for patients with Down Syndrome to allow for cognitive enhancement. Is this a valid designation as “abnormal?” Inexorably linked to this issue would be Autism Spectrum Disorder — where on the spectrum does a cognitive “abnormality” manifest? Further, how do we define potentially less visible disorders such as “anxiety?” With this spectrum of diseases and mental health conditions, variety of measured “abnormalities,” and varying pharmacological treatment effectiveness, I think we need to be mindful that neuroscientific constructions are often blurry, but always need to be conceptualized within the paradigm of ethics.

More than ever, the question of “what is abnormal” and “what mandates treatment” needs to be addressed in pharmaceutical policy. For instance, federally designated controlled substances like marijuana may be effective at treating anxiety and other medical conditions. Should the legal community allow for Eagleman’s assertion to snowball? Imagine an increasing number of states embrace evidence that the active ingredients in marijuana could treat certain medical conditions? Should the scientific community solely argue the validity of these findings? Legal professionals, bioethicists, and regulators need to be included in these questions. It is not that the data driven outcomes need to be pursued; rather, that a level of ethics and sociological morals need to be layered above these decisions.


Country of Origin Labeling for Food and Pharmaceutical Products

by Daniel Schueppert, UMN Law Student, MJLST Staff

The USDA has recently lifted restrictions on the practice of shipping US Chicken to China for processing, for an eventual return to the US. Under the present regulations, chicken originating from US farms can be shipped to China for processing, then shipped back to the US for sale. This chicken need not include Country of Origin Labeling (COOL) to indicate that it has been processed in China. This change comes in the wake of a years of food safety scares relating to China’s food supply. Although the Food Safety Inspection Service (FSIS) has completed audits of the China’s “poultry processing inspection system” and certified some of the Chinese processing plants and procedures, American consumers have retained some reservations about the safety of chicken processed in China. As it stands, this system leaves consumers in the position of not knowing which country their chicken products have been processed because the Chinese operations are considered a comparable food component to what results from US processing.

This recent action by the USDA clearly raises questions concerning the United States’ food safety, and perhaps security. A sophisticated consumer may nevertheless be able avoid chicken products known to be processed in China, but absent COOL disclosures this may be a difficult task and arguably involve some guess work. This is not necessarily the case with generic pharmaceuticals, an area in which there are substantial parallels to the chicken debate. Some of the concerns raised relating to the quality and safety of chicken processed in China also bring to light the COOL requirements for other consumables like pharmaceuticals. Import screening and labeling for pharmaceuticals, and particularly off patent generics, is a convoluted area of regulatory law where Federal agencies to not always agree. Currently many of the various components of just one pharmaceutical drug are manufactured all over the world and come from a variety of sources. Manufacturing in India, China, and Eastern Europe account for a large part of the market.

The FDA’s main measure on determining the quality of components in generic drugs is a fuzzy spectrum concerning the “bioavailability” of certain chemicals but this measure does not necessarily take account of inert components or varying quality or quantities of active ingredients. Much like chicken, a consumer or regulatory agency would be hard pressed to find a problem with these products until a quality control issue develops and American consumers are put at risk. COOL labeling regarding Chicken and Drugs are developing issues without a clear regulatory action in sight. Stay tuned to the Minnesota Journal of Law, Science & Technology for further updates.


United States v. Caronia After-The-Fact: What Was All That Fuss About, Again?

by Ashley Zborowsky, UMN Law Student, MJLST Notes & Comments Editor

Thumbnail-Ashley-Zborowsky.jpgIn a split decision on December 3, 2012, the Second Circuit issued its long-awaited opinion in U.S. v. Caronia–a case concerning off-label promotion and commercial free speech. The 2011 U.S. Supreme Court holding in Sorrell v. IMS Health acknowledging off-label promotion to be “per se” protected under the First Amendment marked a significant shift in this area of law. Previously, the Food and Drug Administration (FDA) was able to recover billions of dollars in penalties from manufacturers engaged in off-label promotion, or the act of promoting regulated products for uses other than those approved by the agency. Despite other challenges on constitutional grounds, the FDA has been successful at defending its current practice–that is, until recently.

After Sorrell, it was unclear how the Second Circuit would apply this precedent in Caronia. For a robust discussion of the holding in Sorrell and alternate regulatory pathways to mitigate the effects of constitutional challenges to FDA authority, see Rethinking Off-Label Regulation in the Wake of Sorrell v. IMS Health: Can State Involvement Compensate for Waning FDA Authority to Curb Commercial Free Speech? Much to the agency’s chagrin, the Second Circuit found that truthful, non-misleading off-label speech is in fact protected by the First Amendment and therefore cannot be prosecuted under the Federal Food, Drug and Cosmetics Act (FDCA). Although the circuit court opinion is not binding outside of its jurisdiction and is only one early example of how Sorrell will be interpreted by lower courts, the Caronia decision signals potentially diminishing regulatory authority in this realm.

To be sure, the gradual constitutional erosion of its authority to police purported FDCA violations is a viable cause for concern–but is it imminent? Though analysts predicted a more panicked response on behalf of the agency, the FDA has apparently decided not to petition the U.S. Supreme Court for certiorari, stating that the agency “does not believe. . . the Caronia decision will significantly affect [ its] enforcement” of off-label promotion. Because of its limited precedential value and the fact that both Sorrell and Caronia only recognize speech that is truthful and non-misleading as protected, the Second Circuit decision may have very little practical effect. In fact just last month in a related case out of the Ninth Circuit, U.S. v. Harkonen, the court chose to ignore Caronia altogether–asserting that the First Amendment does not protect “fraudulent speech.”

While off-label promotion itself cannot form the basis of an FDCA violation under Caronia, it may still be introduced as evidence of criminal misbranding. As such, it seems that the Caronia uproar could have all been for naught. The FDA’s reaction (or lack thereof) to the Second Circuit’s holding indicates that this is likely true. If nothing else, however, Caronia will surely increase the number of constitutional challenges to FDA enforcement activity, forcing the agency to reexamine its priorities. Thus, while Caronia has the potential for wide-ranging implications down the line, industry stakeholders will just have to wait and see. Although Caronia has done little to alter the regulatory landscape presently, it may only be a matter of time before a circuit split begins to evolve.

Reviving GRAS(E): Bringing Reform to the Drug Approval Process

by Maya Suresh, UMN Law Student, MJLST Staff

Thumbnail-Maya-Suresh.jpgBringing new drugs to the market has turned into a time consuming and costly process. Resulting in a process that takes roughly 12 years and 1.2 billion dollars to develop a single new drug and move it through the approval process, the current laws administered by the FDA have the potential to stifle potential economic growth. Current laws and FDA regulations require new drugs to go through three phases of clinical trials focusing on safety, optimal dosage, and effectiveness. It is in the prolonged third phase (where effectiveness is tested through extensive clinical trials) that many manufacturers decide to pull the drug from the program as the clinical trials threaten the firm’s financial viability. Ultimately, it is consumers that are hurt by the process, as they are unable to benefit from the drugs.

The negative effect on consumers is what Emily Puchalski hopes to eliminate with the recommendation detailed in her note published in Issue 14.1 of the Minnesota Journal of Law, Science & Technology. In “Bringing Dormant GRAS(E) to Bloom: Reviving The GRASE Concept for Drugs,” Puchalski suggests that a revival of the Food and Drug Administration’s (FDA) “generally recognized as safe and effective” laws and regulations, commonly reffered to as “GRASE”, could minimize the negative effects on consumers. Many drugs, once discovered, have formulations found in earlier drugs that have already been established as safe for consumer use. The GRASE law is grounded in this understanding, and provides a way for these “already established as safe” drugs to get to the market quicker without having to go through extensive clinical trials.

The problem with GRASE however, is that it is very difficult for a drug to achieve GRASE status. Due to this difficulty, GRASE has fallen out of use as manufacturers have stopped trying to achieve the status. Puchalski suggests that if the FDA were to revive GRASE, it could convince manufacturers to apply for GRASE status, allowing already established safe and effective drugs to come to market more quickly, thus benefiting consumers.

It would appear that Puchalski’s recommendation is being heard. In late February Micropharma Limited was able to obtain GRASE status for their new heart health probiotic. Ryan Jones, CEO of Micropharma Limited, echoed Puchalski when he spoke of the benefits the company has been able to reap with the highly coveted status. GRASE status will allow the company to accelerate development of the drug within both the United States and international markets. Further, it provides strong reputational benefits for the company, as it makes clear to the public that Micropharma is committed to investing a significant amount of time and energy into providing safe and effective drugs to the market.

The ability for Micropharma to obtain GRASE status could serve as evidence of a potentially reformed drug approval process. However, the full benefits realized by consumers and the market will only become clear with time.


Improving Healthcare Quality: Electronic Prescribing

by Johanna Smith, UMN Law Student, MJLSTStaff

Thumbnail-Johanna-Smith.jpgA new study published online on February 20, 2013 in the Journal of the American Medical Informatics Association found that when hospitals used electronic prescribing, it prevented 17 million drug errors–and if implemented more widely and consistently, it could prevent more than 50 million drug errors. But as of 2008, only about one in three acute care hospitals used electronic prescribing. Although there are various methods suggested to improve healthcare quality, one of the simplest is to make medical errors public. If hospitals, and the general public, were more aware of the safety benefits of electronic prescribing, this could lead to increased use and standardization. Another option to increase the use of electronic prescribing is to connect funding or reimbursement to the use of electronic prescribing.

An article in the January 23, 2013 Journal of the American Medical Association reported that once Medicare and Medicaid stopped reimbursing costs due to certain medical errors, the number of times a foreign item was left in a surgical patient dropped by half. The authors note that this number may not be truly accurate, since the hospitals would have financial incentives to hide the errors. Currently, reporting relies mainly on self-reporting by the hospitals, which is not always accurate. A new article in the Minnesota Journal of Law, Science, and Technology (MJLST) by John R. Grout, John W. Hill, and Arlen W. Langvart entitled “Mistake-Proofing Medicine: Legal Considerations and Healthcare Quality Implications,” discusses how to mistake-proof medicine and looks at healthcare quality on a broader level, including electronic prescribing. The MJLST article highlights that many hospital administrators are concerned more with the finances of the hospital than with patient safety. Connecting these two items increases the probability that patient safety will become a priority for hospitals. Although electronic prescribing is not a complete fix for incorrect prescriptions, it is an important part of improving the process. Compared to the cost of medical errors–including incorrect prescriptions–mistake-proofing is generally less expensive.
