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.
With the biggest biosimilar launch in the U.S. just days away, Humira’s (adalimumab) record-breaking ride is quickly slowing down, but the Abbvie Inc. mega-blockbuster immunology drug is nowhere near the end of its road. Meanwhile, the U.S. journey is just beginning for the eight adalimumab biosimilars that could come to market as early as July 1 through licensing agreements with Abbvie. Besides revving their engines against Humira, the new launches will be looking to overtake Amgen Inc.’s biosimilar, Amjevita, which got a five-month headstart in the U.S., thanks to the first-mover status Amgen earned for being the first to sign a licensing agreement with Abbvie.
The U.S. FTC picked up six allies in its unprecedented effort to stop Amgen Inc.’s $27.8 billion acquisition of Horizon Therapeutics plc, as the attorneys general for California, Illinois, Minnesota, New York, Washington and Wisconsin joined the agency in signing onto an amended complaint filed under seal June 22 in the U.S. District Court for the Northern District of Illinois.
The roadmap and conservative substitution methods Amgen Inc. laid out to “enable” its genus claims for antibodies that inhibit PCSK9 to lower LDL cholesterol are “little more than two research assignments,” the U.S. Supreme Court said in a unanimous opinion handed down May 18 in Amgen Inc. v. Sanofi SA that gave the win to Sanofi. The roadmap “merely describes step-by-step Amgen’s own trial-and-error method for finding functional antibodies — calling on scientists to create a wide range of candidate antibodies and then screen each to see which happen to bind to PCSK9 in the right place and block it from binding to LDL receptors,” the court said in the decision written by Justice Neil Gorsuch.
