With the U.S. FDA approval of Attruby (acoramidis) for transthyretin amyloidosis with cardiomyopathy (ATTR-CM), Bridgebio Pharma Inc. is taking on an industry giant. The next-generation, oral, small-molecule stabilizer of transthyretin will take on Pfizer Inc.’s Vyndamax (tafamidis, Vyndaqel), a TTR stabilizer approved in 2019 for ATTR-CM but expected to lose exclusivity in late 2028. The approval was based on a phase III study that showed Attruby significantly reduced death and cardiovascular-related hospitalizations. The NDA, which had a Nov. 29 PDUFA date, was approved Nov. 22.
