Bad news for Amgen Inc. could mean upside for Mirati Therapeutics Inc., though the meeting of the U.S. FDA’s Oncologic Drugs Advisory Committee (ODAC) has yet to tell the tale regarding Lumakras (sotorasib), the former’s KRAS-G12C inhibitor.
As biosimilar development expands beyond monoclonal antibodies to more complex biologics, the flexibility built into regulatory paths across the world will become more essential. Rather than making wholesale changes to those pathways, regulators need to follow the science in exercising the flexibility they already have, Leah Christl, executive director of global biosimilars regulatory affairs and R&D policy at Amgen Inc., told BioWorld. In doing so, “we do need to look forward to what might be coming down the pipeline,” in addition to looking backwards at what types of biosimilars have already been approved, she said.
If the U.S. FDA has its way, biosimilars and interchangeable biosimilars would no longer be a difference with a distinction – at least when it comes to labeling. Instead of distinguishing between the two, the agency is recommending that the labeling for both follow-ons include a “biosimilarity statement.”
Amgen Inc. has patented new quinazoline compounds acting as GTPase KRAS (G12D mutant) inhibitors and thus reported to be useful for the treatment of cancer.
Forget location. It’s timing, timing, timing when it comes to escaping the first round of U.S. Medicare price negotiations due to pending biosimilar competition. Under the Inflation Reduction Act (IRA), only single-source drugs that have been approved for a specific length of time are subject to the forced negotiations, which focus on drugs with the biggest Medicare spend, not necessarily the highest price tag. Since the IRA gives biologics a 12-year safe harbor from negotiations, which aligns with the biologic exclusivity provided by the Biologic Price Competition and Innovation Act, it creates a scenario in which the innovator could be facing negotiations just as its first biosimilar competition prepares to launch. That creates a lot of what-ifs.
Now that the U.S. FDA has nearly 15 years of experience with developing and implementing a biosimilar pathway, it’s time for that regulatory path to catch up with the science, according to experts that have been involved in biosimilar development even before Congress passed the Biologics Price Competition and Innovation Act that created the framework for the U.S. biosimilar market.
The U.S. FTC’s antitrust challenge to Amgen Inc.’s $27.8 billion acquisition of Horizon Therapeutics plc has been resolved. Amgen agreed to do what it said it would do all along: not bundle pharmacy benefit manager rebates on high volume blockbuster drugs Tepezza and Krystexxa.
The U.S. FTC has recalibrated its challenge to Amgen Inc.’s $27.8 billion acquisition of Horizon Therapeutics plc while one of the biggest trade groups has voiced its concerns about the government’s role in the deal. An amicus brief from the Biotechnology Innovation Organization (BIO), along with the Illinois Manufacturers Association, the Chicagoland Chamber of Commerce and the Illinois Biotechnology Innovation Organization, calls the FTC expansion into such deals overreach that chills pro-competitive biopharma mergers.
Nearly 13 years after Congress created a biosimilars path to bring competition to the U.S. biologics market, new rules of the road are coming into play, via the Inflation Reduction Act (IRA), that could change the course for biosimilars in the long haul – if the IRA’s prescription drug price negotiation mandate withstands numerous constitutional challenges.
