BridgeBio's acoramidis, a transthyretin stabilizer, may soon compete with Pfizer's tafamidis for treating transthyretin amyloid cardiomyopathy (ATTR-CM). Acoramidis, with an FDA action date of Nov. 29, could see approval, potentially challenging Pfizer's established position in the $5.2 billion ATTR-CM market. BridgeBio's Phase III trial showed acoramidis improved survival rates and reduced hospitalizations, though it faces challenges like twice-daily dosing and lack of mortality benefit data compared to tafamidis. Emerging RNA therapies, like Alnylam's Amvuttra and Intellia's nex-z, also show promise in treating ATTR-CM.
