FDA to Publish Biosimilars Labeling, Generic Opioids Guidance Later This Year

Posted 27 February 2015 By Alexander Gaffney, RAC


US pharmaceutical regulators with the US Food and Drug Administration's (FDA) Center for Drug Evaluation and Research (CDER) say they plan to release two new guidance documents on, separately, the labeling of biosimilar products and how companies can evaluate abuse-deterrent properties of generic solid oral opioid drugs.

News of the new guidance documents, which FDA anticipated will come out before the end of the year, came in an updated "Guidance Agenda" document the agency puts out each year. CDER's current list of documents now contains more than 90 guidance documents it plans to either release or finalize in the coming year.

Biosimilar Labeling

The biosimilar labeling guidance is seen by many industry watchers as particularly important, as it will need to address several critical issues essential to the approval of the US' first biosimilar products, which are already under review by CDER. In particular, FDA will need to decide what "generic" name each biosimilar product will go by. Unlike generic pharmaceutical products, which are identical copies of their chemical innovators, biosimilar drugs have inherent differences relative to the biological drug they reference.

To account for these differences—and the potential for each drug to cause slightly different side effects—some have advocated for biosimilars to contain unique suffixes to make the reporting of adverse events easier.

For more on this debate and its nuances, please see a previous article on the subject here.

Industry watchers will undoubtedly be keeping a close eye on how—or whether—FDA chooses to differentiate biosimilar products from the products they reference in its upcoming guidance, Labeling for Biosimilar Biological Products.

Abuse Deterrence Guidance

A second guidance document just added to FDA's list focuses on the abuse deterrent qualities of generic opioids—long a controversial topic at the agency.

At issue: After an opioid is approved, its manufacturer often works to improve its abuse-deterrent qualities to make it harder to misuse and abuse. However, these new qualities do not necessarily extend the original drug's patent protection or marketing exclusivity. As a result, FDA may subsequently approve drugs generic to the original—i.e. non-abuse-deterrent—opioid drug.

FDA has defended this practice by saying it is up to manufacturers to prove that their new abuse-resistance measures actually live up to their claims and deter abuse, and that without such data it is under no obligation to prevent generic competition.

Some industry trade groups and legislators, meanwhile, have called on FDA to change its standards in light of the potential for these generic drugs to increase rates of abuse. In January 2015, for example, industry groups PhRMA and BIO called on the agency to hold generic opioid products to the same abuse-deterrence standards as the most recently approved abuse-deterrent opioid.

Now FDA appears poised to weigh in on the issue. Later this year, FDA will publish the guidance General Principles for Evaluating Abuse-Deterrent Properties of Generic Solid Oral Opioid Drug.
