How Attruby Works

Stability

The only FDA-approved treatment described as achieving near-complete (>90%) in vitro TTR stabilization in its label1,2

  • Designed to mimic the protective properties of the T119M variant1,2
  • Rational design enables enthalpy-driven TTR stabilization due to the formation of hydrogen bonds deep in the T4 binding pocket, slowing the rate of dissociation into monomers3,4

Important Safety Information and Indication

Important Safety Information

Adverse Reactions
Diarrhea (11.6% vs 7.6%) and upper abdominal pain (5.5% vs 1.4%) were reported in patients treated with Attruby versus placebo, respectively. The majority of these adverse reactions were mild and resolved without drug discontinuation.
Discontinuation rates due to adverse events were similar between patients treated with Attruby versus placebo (9.3% and 8.5%, respectively).

Laboratory Tests
Mean increase in serum creatinine of 0.2 and 0.0 mg/dL and a mean decrease in eGFR of 8.2 and 0.7 mL/min/1.73 m2 was observed in the adults with ATTR-CM treated with Attruby versus placebo, respectively, at Day 28 and then stabilized. These changes were reversible after treatment discontinuation.

Use in Specific Populations

Pregnancy & Lactation: There are no data on the use of Attruby in pregnant women. Animal data have not shown developmental risk associated with the use of Attruby in pregnancy. There are no available data on the presence of Attruby in either human or animal milk or the effects of the drug on the breastfed infant or maternal milk production.

Indication

Attruby® (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.

More information on DDIs1

Avoid concomitant use of Attruby (acoramidis) with UGT inducers and strong CYP3A inducers, as these can potentially decrease Attruby exposure.

Consider more frequent monitoring for evidence of increased exposure to CYP2C9 substrates when Attruby (acoramidis) is coadministered with sensitive CYP2C9 substrates.

CYP=cytochrome P450; DDI=drug-drug interaction; UGT=uridine diphosphate glucuronosyltransferase.
