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.
The U.S. FTC’s unprecedented antitrust challenge to Amgen Inc.’s $27.8 billion acquisition of Horizon Therapeutics plc, could be a disruptor to biotech investment if the agency is victorious, some analysts are warning. “With essentially zero commercial overlap [between the two companies], this deal would seem to be a slam dunk under long-established antitrust considerations,” said Christopher Raymond, a senior research analyst with Piper Sandler Research.
Amgen Inc. and Tscan Therapeutics Inc. have entered into a multi-year collaboration that will use Tscan’s proprietary target discovery platform, Targetscan, to identify the antigens recognized by T cells in patients with Crohn’s disease.
Tscan Therapeutics Inc.’s Wall Street-pleasing deal with Amgen Inc. in Crohn’s disease (CD) could expand into ulcerative colitis, but meanwhile is bringing $30 million up front with the potential for more than $500 million in preclinical, clinical, regulatory and commercial milestone payments, plus tiered single-digit royalties. Shares of Waltham, Mass.-based Tscan (NASDAQ:TCRX) closed May 9 at $3.40, up $1.25, or 58%, as the world learned of the multiyear collaboration with Amgen, of Thousand Oaks, Calif., that will use Tscan’s target discovery platform, Targetscan, to identify the antigens recognized by T cells in patients with CD.
