Acoramidis, sold under the brand name Attruby, is a medication used for the treatment of cardiomyopathy.[1] It is a near-complete (>90%) transthyretin stabilizer, developed to mimic the protective properties of the naturally-occurring T119M mutation,[2][3] to treat transthyretin amyloid cardiomyopathy. It is taken by mouth.[1]

The most common adverse reactions include diarrhea and upper abdominal pain.[4]

Acoramidis was approved for medical use in the United States in November 2024.[4][5][6]

Medical uses

[edit]

Acoramidis is indicated for the treatment of the cardiomyopathy of wild-type or variant transthyretin-mediated amyloidosis (ATTR-CM) in adults to reduce cardiovascular death and cardiovascular-related hospitalization.[1][4][7]

ATTR-CM is a rare and serious disease that affects the heart muscle.[4] In people with ATTR-CM, there is a build-up of protein deposits in the heart, causing the walls of the heart to become stiff, and making the left ventricle unable to properly relax and fill with blood (called cardiomyopathy).[4] As the condition progresses, the heart can become unable to pump blood out adequately, causing heart failure.[4] There are two types of ATTR-CM, hereditary ATTR-CM (hATTR-CM) and wild-type ATTR-CM (wATTR-CM).[4] In hATTR-CM, which can run in families, there's a variant in the transthyretin gene, which results in protein deposits in the heart. In wATTR-CM, there is no variant in the transthyretin gene.[4]

Side effects

[edit]

The most common side effects are diarrhea and abdominal pain.[8]

History

[edit]

The efficacy and safety of acoramidis were evaluated in a multicenter, international, randomized, double-blind, placebo-controlled study in 611 adult participants with wild-type or hereditary (variant) ATTR-CM (NCT03860935).[4]

Clinical trials

[edit]

Phase I data indicated acoramidis achieved near-complete (>90%) TTR stabilization across the entire dosing interval at steady state.[9]

Phase II 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. [10]

Phase III 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 participants with ATTR-CM. Adverse events were similar in the two groups.[11]

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 participants with ATTR-CM.[12][13][14]

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.[15]

Society and culture

[edit]
[edit]

Acoramidis was approved for medical use in the United States in November 2024.[4][5][16] The approval was granted to BridgeBio Pharma.[7]

In December 2024, the Committee for Medicinal Products for Human Use of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Beyonttra, intended for the treatment of transthyretin amyloidosis in adults with cardiomyopathy.[17] The applicant for this medicinal product is BridgeBio Europe B.V.[17]

Acoramidis was designated an orphan medicine by the EMA.[17]

Names

[edit]

During development, acoramidis was known as AG10 (the Alhamadsheh-Graef molecule 10).[18]

Acoramidis is the international nonproprietary name.[19]
