3 Challenges to Patents on Therapeutic Monoclonal Antibodies

By Gregory Curfman

Three new developments — two based on litigation and one based on a federal statute — may have significant effects on pharmaceutical manufacturers’ use of patents to fend off competition and maintain high prices for therapeutic monoclonal antibodies.

Highly specific monoclonal antibodies have played an increasingly important role as precision therapies for a growing number of diseases, including malignant, cardiovascular, and inflammatory conditions. As therapies derived from research and development, therapeutic monoclonal antibodies may be — and usually are — patented, providing manufacturers with protection from competition and the prospect of high revenues.

AbbVie Wins First Round in Humira Antitrust Lawsuit

By Ryan Knox and Gregory Curfman

Since receiving FDA approval for Humira® (adalimumab) in 2002, AbbVie, the drug’s manufacturer, has filed hundreds of submissions to the U.S. Patent and Trademark Office for secondary patents – almost half of which were filed after 2014, just two years before the expiration of its core patent.

These patents were largely directed to methods of use and potential formulation changes, but they did not include claims that affect the clinical efficacy of the biologic, which is used in the treatment of rheumatoid arthritis, Crohn’s disease, and psoriasis, among other conditions. Instead, the purpose of the secondary patent filings was to assemble a thicket of patents, 132 in all, to prohibit competition from biosimilar companies.

And so far, the strategy has worked. AbbVie remains the sole U.S. manufacturer of the biologic, and has successfully defended its domain: in June 2020, a federal district court judge in Chicago dismissed an antitrust lawsuit against AbbVie.

To Cut Prescription Drug Spending, Stop Delays for Generic Competition

By Beatrice Brown and Benjamin Rome

Prescription drug spending in the U.S. remains high and continues to rise, accounting for about 20% of national health expenditures. While generic competition is crucial for reducing drug prices, brand-name drug manufacturers can utilize several strategies to delay such competition by increasing the length of market exclusivity for their drugs.

Although brand-name drugs only account for 18% of all prescriptions filled, they comprise 78% of total drug spending. By contrast, equally-effective, interchangeable generic drugs can offer discounts of up to 80% off their brand-name drug counterparts.

Generic competitors can only be introduced after brand-name drugs have completed their period of market exclusivity, which typically lasts 12-16 years and is largely determined by the patents covering the drug. Brand-name pharmaceutical manufacturers have strong financial incentives to prolong this market exclusivity period and delay entry of generic products.

New Study Provides Insights into Potential Regulatory Treatment of COVID-19 Drugs

By Beatrice Brown

As the global pandemic continues, trials have been established to test whether existing drugs such as hydroxychloroquine could be repurposed to treat patients with COVID-19. There are also hopes that a novel drug will surface. But questions remain about when treatments and vaccines will become available.

There is currently great optimism that a treatment or vaccine will be developed quickly, but there is no assurance that such a vaccine or treatment will be highly effective or that normalcy will return in any particular timeframe. A recent study published in the Lancet ID by Jonathan J. Darrow, Mehdi Najafzadeh, Kristina Stefanini, and Aaron S. Kesselheim provides data that might help to temper enthusiasm with evidence.

World Trade Month: Trade’s impact on domestic drug prices

By Oliver Kim

Happy World Trade Month! While health policy is often seen as something particularly domestic, trade can have an impact on health policy here at home.

Just a day before President Trump’s speech outlining the administration’s approach to rising drug costs, the Pharmaceutical Research and Manufacturers of America (PhRMA) declared May as a time to “celebrate the many American companies exporting products around the world.” However, PhRMA also warned that “Americans should not subsidize the medicine costs in other wealthy countries.”

Drug Law Factoids for Your Consideration

By Scott Burris

This is a succinct paragraph from the weekly newsletter of U. Maryland’s Center for Substance Abuse Research. Seems relevant both to the conference on law  enforcement and public health I reported on earlier this week, and the election results on marijuana:

There were an estimated 12,408,899 arrests in the United States in 2011, according to data from the national Uniform Crime Reporting (UCR) Program. The highest number of arrests were for drug abuse violations—selling, manufacturing, or possessing drugs, followed by larceny-theft and driving under the influence. The majority (82%) of these arrests were for possession and one-half of these drug abuse violations involved marijuana. A poll conducted in 2011 found that one-half of U.S. residents think that marijuana should be legalized (see CESAR FAX, Volume 21, Issue 19).
