Transthyretin cardiomyopathy
ATTRibute-CM: Acoramidis Linked to Improved clinical outcomes in transthyretin amyloid cardiomyopathy
Key Points:
- Transthyretin amyloid cardiomyopathy develops because of mis-folded proteins infiltrating the myocardium, leading to clinical heart failure. Currently, tafamidis is the only commercially approved medication and is the most expensive cardiovascular drug on the market.
- Acoramidis is a once-daily medication that stabilizes the transthyretin tetrameric protein, preventing its degradation and subsequent deposition into the myocardium.
- Acoramidis in ATTR-CM resulted in a statistically significant reduction in hospitalization for heart failure and mortality based on a hierarchical analysis of a composite outcome with an overall win ratio of 1.8 (p<0.0001) compared to placebo.
Tafamidis, A Real Hope for People with Transthyretin Cardiomyopathy?
On Thursday, March 29th, Pfizer announced positive topline results from ATTR-ACT trial of tafamidis in patients with transthyretin cardiomyopathy. According to Pfizer, “Tafamidis met its primary endpoint, demonstrating a statistically significant reduction in the composite of all-cause mortality and frequency of cardiovascular-related hospitalizations compared to placebo at 30 months. The preliminary safety data showed that tafamidis was generally well tolerated in this population and no new safety signals were identified”. Continue reading
