A West Virginia College authorized scholar says present legal guidelines could also be giving producers of biologic medicine, like antibodies and flu vaccines, an excessive amount of in the way in which of authorized protections earlier than copycat variations will be offered when put next with conventional small-molecule medicine, together with antibiotics and steroids.
In an article within the JAMA, Sean Tu, professor on the WVU School of Regulation, appears to be like on the Meals and Drug Administration exclusivity given to every of those various kinds of medicine and whether or not biologics actually need longer protections than small-molecule medicine. Tu argues that whereas there ought to be parity, the answer is to not elevate the small-molecule exclusivity time however to lower the exclusivity time on biologics.
“Small molecule drugs are chemical compounds that are relatively easy to make,” Tu stated. “I put it in a test tube, add the chemicals, and I’m going to get the same reaction every time, whether I make it here in West Virginia versus Canada or France, because the chemistry is the same.”
In contrast, biologics are manufactured in dwelling organisms. Antibodies, for instance, are created in dwelling cells and are affected by varied components in the course of the course of.
“The temperature you keep them at, what you feed them, the serum you use—all of that can change the product slightly,” he stated. “So, the product I make here in West Virginia may be different from the product that I make in Canada or France. And because of that, there are some issues that make biologics harder to produce than small-molecule drugs.”
Each biologics and small-molecule medicine take about 12–13 years to develop. Biologics price barely extra to develop—$3 billion vs. $2.1 billion, on common—and have stronger patent safety, with extra patents per drug. Moreover, biologics earn a lot larger revenues, each at their peak and general, and are considerably dearer for sufferers in comparison with small-molecule medicine.
FDA market exclusivities forestall the company from even approving a drug throughout that interval. Biologics get 12 years of safety earlier than copycat variations will be accepted. In contrast, small-molecule medicine are given 5 years of market exclusivity. Moreover, the Inflation Discount Act of 2022 states that biologics are exempt from Medicare worth negotiations for 11 years, in comparison with seven years for small-molecule medicine.
Biologics like Humira, Keytruda and Stelara comprise roughly 5% of all medicine and make up 40% of complete pharmaceutical spending. Most are injected in a hospital setting. They’re costly, so that they have a disproportionate impact on the price of pharmaceuticals.

Nevertheless, it does not imply they’re simpler.
“We wrote this paper because the small-molecule folks say nobody’s going to invest in small molecules now—everybody’s going to invest in biologics because they get longer protections and they make more money,” Tu stated. “But small-molecules are great drugs. Some actually cure the disease, like the direct acting antiviral drugs that can cure hepatitis C in just 12 weeks.”
Tu labored with fellow authors Olivier Wouters, London College of Economics; Matthew Vogel, Harvard; Reed Beall, College of Calgary; and William B. Feldman and Aaron Kesselheim, each of Harvard Medical College. The group analyzed knowledge on improvement occasions, scientific trial success charges, analysis and improvement prices, patent safety, market exclusivity durations, revenues and therapy prices of biologics versus small-molecule medicine.
They discovered patents on biologics could also be simpler at delaying biosimilar entry than patents on small-molecule medicine are at delaying generic entry. One technique that biologic producers have employed has been to acquire new patents simply as 12-year exclusivity durations expire, thereby creating uncertainty for biosimilar companies searching for to problem biologic patents. Moreover, biologic companies get hold of nearly 5 occasions as many patents to cowl their merchandise in comparison with small-molecule medicine. Because of this market exclusivity durations seem like a number of years longer for biologics.
The group noticed little proof to justify giving biologics longer authorized protections. Biologics have already got stronger patent safety, longer durations with out competitors and better revenues than small-molecule medicine.
“The Biologic Price Competition and Innovation Act granted biologics 12 years of exclusivity based on the assumption that biologics would face earlier competition, have fewer patents, encounter greater challenges during FDA approval, and ultimately generate less revenue over time. However, our analysis shows that each of these assumptions were incorrect.”
Tu stated the Trump administration could deal with the difficulty of parity.
“Congress should reduce the exclusivity period for biologics from 12 years to five years to bring the biologic exclusivity time in parity with small-molecule drugs. Reducing exclusivity for biologics could lower drug costs.”
