BridgeBio Pharma's acoramidis (Attruby) wins FDA approval for treating ATTR cardiomyopathy, competing with Pfizer's tafamidis. Attruby, a near-complete TTR stabilizer, aims to reduce cardiovascular death and hospitalization. Despite initial trial setbacks, 30-month data supported approval, positioning Attruby as the first oral stabilizer with near-complete stabilization claims. BridgeBio estimates a $15-20 billion market, dominated by Pfizer, with Alnylam and AstraZeneca also entering the space. Attruby's pricing is competitive but above cost-effectiveness benchmarks, with ongoing European review and a Bayer licensing deal.
