Acoramidis

Acoramidis /ə-corAM’-i-dis/ (formerly AG10, named for "Alhamadsheh-Graef molecule 10") is an investigational, near-complete (>90%) transthyretin stabilizer, developed to mimic the protective properties of the naturally-occurring T119M mutation,[1][2] to treat transthyretin amyloid cardiomyopathy. It is delivered by mouth. An alternative treatment is tafamidis.[3][4][5] Acoramidis is pending FDA approval (PDUFA Nov. 29, 2024) for the treatment of both wild-type and hereditary transthyretin amyloid cardiomyopathy (ATTR-CM) to reduce cardiovascular death and hospitalization.

In vitro data indicated acoramidis exhibits near-complete (>90%) TTR stabilization at therapeutic trough concentrations, and its TTR stabilization exceeds that of tafamidis' across a range of destabilizing TTR mutations.[6]

Phase 1 data indicated acoramidis achieved near-complete (>90%) TTR stabilization across the entire dosing interval at steady state.[7]

Phase 2 and the Open-Label Extension (OLE) data indicated after a median of 38 months, long-term treatment with acoramidis was generally well tolerated and resulted in a median decline in NT-proBNP levels, normalization of serum TTR, and sustained stabilization of TTR in individuals with ATTR-CM. [8]

Phase 3 data from ATTRibute-CM indicated acoramidis resulted in a significantly better four-step primary hierarchical outcome containing components of mortality, morbidity, and function than placebo at 30 months in patients with ATTR-CM. Adverse events were similar in the two groups.[9]

Other analyses from ATTRibute-CM indicated a 50% reduction in cumulative cardiovascular hospitalizations (CVH), a 42% reduction in all-cause mortality (ACM) and recurrent CVH, and a 3-month time-to-separation of the Kaplan Meier curves for ACM or CVH. No other treatment has demonstrated this degree of treatment effect this quickly in patients with ATTR-CM.[10][11][12][13]
