Acoramidis Begins to Reduce Cumulative Cardiovascular Outcomes Within the First Month of Treatment in Patients with ATTR-CM

September 28, 2025 11:15 ET | Source: BridgeBio Pharma, Inc. - By Month 1, numerically fewer cumulative events were observed with acoramidis compared to placebo- Acoramidis significantly reduced the cumulative risk of CVM or recurrent CVH through Month 30 versus placebo with a 49% hazard reduction (p<0.0001)- The difference in cumulative events increased progressively with results at Month 30 showing 53 events were avoided per 100 treated participants (95% CI:29–79)PALO ALTO, Calif., Sept. 28, 2025 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a new type of biopharmaceutical company focused on genetic diseases, presented data from the ATTRibute-CM study showing that acoramidis reduced cumulative cardiovascular outcomes, including cardiovascular mortality (CVM) or recurrent cardiovascular-related hospitalizations (CVH), within the first month of treatment in patients with ATTR-CM. These data were presented in a Late Breaking Clinical Trials Oral Presentation at the Heart Failure Society of America (HFSA) Annual Scientific Meeting (ASM) 2025 and simultaneously published in Journal of the American College of Cardiology. Acoramidis is a selective, small molecule, orally administered, near-complete (≥90%) transthyretin (TTR) stabilizer.“Acoramidis demonstrated early and sustained clinical efficacy on the totality of cumulative cardiovascular outcomes, where accrued events start to numerically diverge within the first month of treatment,” said Ahmad Masri, M.D., M.S. of Oregon Health & Science University. “As a practicing cardiologist, these findings are incredibly meaningful because it draws attention to the time-sensitive nature of transthyretin amyloidosis diagnosis and treatment initiation, where a safe and effective treatment such as acoramidis can potentially have an early effect on reducing patients' risk of cardiovascular hospitalizations and events.”Details from the late breaking oral presentation, Effect of Acoramidis on Recurrent and Cumulative Cardiovascular Outcomes in ATTR-CM: Exploratory Analysis from ATTRibute-CM, presented by Dr. Masri included:At Month 1, numerically fewer cumulative events were observed with acoramidis compared to placeboAcoramidis significantly reduced the cumulative risk of CVM or recurrent CVH through Month 30 versus placebo with a 49% hazard reduction (p<0.0001)The difference in cumulative events increased progressively with results at Month 30 showing 53 events were avoided per 100 treated participants (95% CI:29–79)In addition to the late breaking oral presentation, a simultaneous publication in Journal of the American College of Cardiology, with the same title as the presentation, noted the same details and also concluded that at Month 42, CVM was reduced with continuous acoramidis versus placebo-to-acoramidis with a hazard reduction of 45% (p=0.0011)In addition to the late breaking oral presentation and simultaneous publication of the cumulative cardiovascular outcomes data from ATTRibute-CM, one oral presentation and three poster sessions were shared on the open-label extension data from ATTRibute-CM and real-world evidence. These findings included:Continuous Acoramidis Treatment Significantly Reduced Risk of All-cause Mortality and Cardiovascular-related Hospitalization at Month 42, in Patients with Wild-type And Variant Transthyretin Amyloidosis Cardiomyopathy, shared in an oral presentation by Lily Stern, M.D. of Cedars-Sinai Heart InstituteAt Month 42, continuous acoramidis was associated with lower risk of all-cause mortality (ACM), first CVH, and ACM/first CVH vs placebo to acoramidis switch in both wild-type ATTR-CM and variant ATTR-CM, highlighting the importance of early and continuous acoramidis regardless of TTR genotypeAcoramidis Mitigates the Rise in NT-proBNP Levels Observed with Placebo in Patients with Variant Transthyretin Amyloid Cardiomyopathy: Results from ATTRibute-CM, presented in a poster session by Nitasha Sarswat, M.D. of UChicago MedicineIn the variant ATTR-CM subpopulation from ATTRibute-CM, acoramidis consistently mitigated the rise in N-terminal pro-B-type natriuretic peptide (NT-proBNP) observed in the placebo variant group, with effects starting at Month 3, and continuing through Month 30. Considering the higher risk posed by variant ATTR-CM, these findings are especially relevant in addressing the distinct medical needs of the variant ATTR-CM patient populationEffect of Acoramidis on Cardiac Conduction Abnormalities in Transthyretin Amyloid Cardiomyopathy, presented in a poster session by Brett W. Sperry, M.D. of Saint Luke's Health SystemIn ATTRibute-CM, acoramidis treatment was associated with numerically lower percentages of participants with worsening, prolonged PR or QRS intervals at Month 24 and Month 30, compared with placebo. These observations are consistent with the slowing of ATTR-CM disease progression previously reported with acoramidisState-Level Differences in Incidence of Transthyretin Amyloid Cardiomyopathy in United States Veterans Persist After Introduction of Disease-Modifying Therapy, presented in a poster session by Sandesh Dev, M.D. of Arizona State UniversityThe incidence of ATTR-CM in the U.S. Veteran population increased nationally in the setting of available treatment, possibly due to improved awareness in most statesAcoramidis is approved as Attruby® by the U.S. FDA and is approved as BEYONTTRA® by the European Commission, Japanese Pharmaceuticals and Medical Devices Agency, and the UK Medicines and Healthcare Products Regulatory Agency with all labels specifying near-complete stabilization of TTR.More data on the benefit of Attruby for ATTR-CM patients is planned for future medical meetings.About Attruby™ (acoramidis) INDICATION Attruby is a transthyretin stabilizer 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.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).About BridgeBio BridgeBio Pharma (BridgeBio; NASDAQ:BBIO) is a new type of biopharmaceutical company founded to discover, create, test, and deliver transformative medicines to treat patients who suffer from genetic diseases.
