- In a post-hoc analysis of ATTRibute-CM, acoramidis reduced the annual frequency of CVH due to AF/AFL by 43% compared to placebo and reduced the incidence of new-onset AF/AFL by 17% in the subgroup with no prior history of AF compared to placebo - In the ATTRibute-CM study, acoramidis demonstrated the most rapid benefit seen in any Phase 3 study of ATTR-CM to date in both ATTRv-CM and ATTRwt-CM patients: - In as few as 3 months, the time to first event (ACM or CVH) durably separated relative to placebo- A 42% reduction in composite ACM and recurrent CVH events relative to placebo at Month 30- A 50% reduction in the cumulative frequency of CVH events relative to placebo at Month 30 - Acoramidis 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 UK Medicines and Healthcare Products Regulatory Agency PALO ALTO, Calif., May 20, 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 ATTRibute-CM, highlighting the reduced incidence of atrial fibrillation (AF) events in the overall ATTR-CM population. These data were presented in a moderated ePoster at the Annual Congress of the Heart Failure Association of the ESC (Heart Failure 2025), taking place in Belgrade, Serbia from May 17 - 20, 2025. Acoramidis is a selective small molecule, orally administered, near-complete (≥90%) transthyretin (TTR) stabilizer. “The reduction in new-onset atrial fibrillation and AF-related hospitalizations represents an important finding for the ATTR-CM community. I am encouraged by the growing body of data from the ATTRibute-CM study, which adds to the understanding of acoramidis and its potential impact on clinical outcomes for patients. Furthermore, the observed reductions in hospitalizations and mortality, along with improvements in functional capacity and quality of life, suggest that acoramidis may offer benefit to both variant and wild-type ATTR-CM patients who have limited treatment options,” said Kevin Alexander, M.D. of Stanford University School of Medicine, USA. “These data support further consideration of acoramidis as a promising front-line therapy for ATTR-CM, particularly for patients with the hereditary form of the disease, who often face rapid and severe progression.” Details from the post-hoc analysis on incidence of AF in ATTRibute-CM included: Acoramidis Treatment Is Associated with a Lower Incidence of Atrial Fibrillation-related Events in Patients with ATTR-CM: A Post-hoc Analysis of the ATTRibute-CM Trial, presented by Dr. Alexander AF is a common complication of ATTR-CM, observed in up to 70% of patients, and the onset of AF is associated with an increased risk of cardiovascular-related hospitalizations (CVH)In ATTRibute-CM, a 43% relative risk reduction in the annual frequency of CVH due to AF/atrial flutter (AFL) was observed with acoramidis relative to placebo. In the subgroup who had no prior history of AF, a 17% lower incidence of new-onset AF/AFL was reported with acoramidis compared to placeboThese findings show the potential of acoramidis to reduce both disease progression, as indicated by a lower incidence of new-onset AF/AFL, and CVH morbidity caused by AF/AFL, in patients with ATTR-CM In addition to the moderated ePoster, three analyses were shared on the strong clinical outcomes in ATTRv-CM versus placebo. ATTRv-CM is associated with early age of disease onset with more advanced heart failure symptoms, which often leads to a poorer prognosis than those with wild-type ATTR-CM (ATTRwt-CM). These findings included: Acoramidis Improves Serum TTR Levels in Patients with Wild-type or Variant Transthyretin Amyloid Cardiomyopathy: Results from ATTRibute-CM, presented by Anique Ducharme, M.D. of Université de Montréal, CAN In both subgroups of ATTRv-CM and ATTRwt-CM, acoramidis treatment induced a rapid increase in serum TTR levels, a measure of TTR stability, by Day 28, with comparable serum TTR levels achieved in both subgroups from Day 28 through Month 30. Relative increases in serum TTR concentrations resulting from greater TTR stability have been associated with reduced risk of all-cause and cardiovascular mortality in the general population in recent literature1 Effect of Acoramidis on Functional Capacity and Quality of Life in Patients with Variant ATTR-CM: Results from ATTRibute-CM, presented by Marianna Fontana, M.D. of University College London, UK Data from ATTRibute-CM showed that when acoramidis was administered for 30 months, participants with ATTRv-CM had a clinically significant slower decline in functional capacity and quality of life compared with placebo, consistent with the overall results in both ATTRv-CM and ATTRwt-CMAt Month 30, the mean difference between acoramidis and placebo treatment groups in the change from baseline in 6-minute walk distance was 86.7 meters (p = 0.0048) in favor of acoramidis and in the change from baseline in KCCQ-OS at Month 30, was 20.3 points (p = 0.0019) in favor of acoramidis, in patients with ATTRv-CM Effect of Acoramidis on All-cause Mortality, Cardiovascular Hospitalization and NT-proBNP in Variant ATTR-CM: Results from ATTRibute-CM, presented by Marianna Fontana, M.D. of University College London, UK In ATTRibute-CM, acoramidis treatment administered for 30 months led to a substantial reduction (>50%) in the composite of all-cause mortality (ACM)/CVH, ACM and CVH in participants with ATTRv-CM compared to placebo. This improvement was accompanied by favorable effects on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels “Based on the findings from ATTRibute-CM, we believe that acoramidis has the potential to enable patients with both variant and wild-type ATTR-CM to live longer, healthier lives, especially for those with variant ATTR-CM who typically have a poorer prognosis. We observed both a striking reduction in the frequency of cardiovascular hospitalizations (which included clinic or emergency department visits for urgent heart failure management) and a clinically important and statistically significant reduction in all-cause mortality in the important subgroup. These clinical outcomes were further mirrored in robust improvements in functional capacity, quality of life, and biomarkers of heart failure severity,” said Jonathan Fox, M.D., Ph.D., President and Chief Medical Officer of BridgeBio Cardiorenal. “Given these compelling results, acoramidis should be considered as first-line treatment for newly diagnosed patients, and those currently on other therapies could be switched to acoramidis to maximize their potential to achieve such benefits.” Additional acoramidis moderated ePosters at Heart Failure 2025 included: Disease Progression Among Patients Receiving Tafamidis for ATTR-CM in a Real-world Setting, presented by Daniel P. Judge, M.D. of Medical University of South Carolina, USA This analysis suggests disease progression despite treatment with tafamidis in ATTR-CM. CVH was frequent, with approximately 1 in 5 tafamidis-treated patients hospitalized in the first six months of therapy. As more therapeutic options become available, measuring the clinical effectiveness of therapies in a real-world setting will be important to help inform physicians and patients when making treatment decisions Cause of Death in Patients with Transthyretin Amyloid Cardiomyopathy (ATTR-CM): Findings from the ATTRibute-CM Study, presented by Laura Obici, M.D. of University of Pavia, ESP In the ATTRibute-CM study, total deaths were numerically lower with acoramidis compared with placebo. The relative risk reduction of 30% in cardiovascular-related mortality by Month 30 was driven predominantly by a reduction in heart failure-related deaths Time from First Recorded Clinical Manifestation to Diagnosis of Transthyretin Amyloid Cardiomyopathy: A Retrospective Cohort Study Using U.S. Claims Data, presented by Joshua Mitchell, M.D., Washington University School of Medicine in St. Louis, USA The median time from the first documented clinical manifestation to ATTR-CM diagnosis was almost 5 years, and over 2 years from the first heart failure diagnosis. This demonstrates that the patient journey to an ATTR-CM diagnosis can be prolonged and challenging, which potentially leads to more severe disease at diagnosis. Understanding the factors contributing to diagnostic delays is important to improving diagnostic pathways and patient outcomes Acoramidis 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. 1Christoffersen M et al.

- For each 5-mg/dL increase in serum TTR level within 28 days of starting treatment, the relative risk reduction of mortality was up to 31.6% through Month 30, confirming the hypothesis that ever better levels of stabilization achieved by treatment with acoramidis, a near-complete (≥90%) TTR stabilizer, lead to ever better clinical outcomes - ATTRibute-CM is the only study to demonstrate a direct association between a prompt, sustained increase in serum TTR and survival in patients with ATTR-CM - The open-label extension data for all ATTRibute-CM participants at Month 42 showed that rapid, sustained TTR stabilization from acoramidis demonstrated statistically significant reductions in ACM and CVH (including urgent outpatient treatment for heart failure exacerbations) - In the ATTRibute-CM study, acoramidis demonstrated the most rapid benefit seen in any Phase 3 study of ATTR-CM to date in both ATTRv-CM and ATTRwt-CM patients: - In as few as 3 months, the time to first event (ACM or CVH) durably separated relative to placebo - A 42% reduction in composite ACM and recurrent CVH events relative to placebo at Month 30 - A 50% reduction in the cumulative frequency of CVH events relative to placebo at Month 30 - Acoramidis is approved as Attruby™ by the U.S. FDA and is approved as BEYONTTRA ® by the European Commission, the Japanese Pharmaceuticals and Medical Devices Agency, and the UK Medicines and Healthcare Products Regulatory Agency PALO ALTO, Calif., May 19, 2025 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a new type of biopharmaceutical company focused on genetic diseases, published data showing that an early, sustained increase in serum transthyretin (TTR) levels predicted improved survival in ATTRibute-CM, its Phase 3 trial of acoramidis in transthyretin amyloid cardiomyopathy (ATTR-CM). These findings were published in Journal of the American College of Cardiology (JACC) in the Special Focus Issue: Amyloid . Acoramidis is a selective, small molecule, orally administered, near-complete (≥90%) TTR stabilizer. These findings further support the thesis that ever better increases in serum TTR lead to ever better clinical outcomes and that early elevations in serum TTR are an important prognostic marker to inform treatment selection. “Patients with ATTR-CM have progressive amyloid accumulation in the heart, which when untreated manifests as progressive heart failure, arrhythmias, and eventually can result in death. Increases in serum TTR seen with acoramidis therapy within 28 days of initiation and that were sustained with therapy, were associated with a decrease in all-cause mortality independent of baseline risk among subjects in the ATTRibute-CM trial. The increase in serum TTR is hypothesized to be due to a leftward shift in amyloidogenic TTR to a more stable tetrameric TTR. This is the first concrete evidence that there is a link between this rapid increase in serum TTR and survival. Such data may inform clinical practice, as early and sustained increases in serum TTR could represent a new potential ATTR disease-specific and prognostic biomarker that may further inform clinical decisions in optimizing care for ATTR-CM patients,” said Mathew Maurer, M.D. of Columbia University Irving Medical Center. In patients with ATTR-CM, aging or an inherited variant can cause tetrameric TTR to destabilize and misfold, causing buildup of amyloid fibrils in the organs, specifically in the heart. These data demonstrate that by using acoramidis, a selective near-complete TTR stabilizer to bind serum TTR, a rapid and sustained increase in tetrameric TTR was independently associated with an improvement in overall survival, even after adjustment for known predictors like TTR variant status, baseline New York Heart Association (NYHA) functional class, baseline National Amyloidosis Centre (NAC) stage, and baseline serum TTR levels. Findings from the analysis included: Treatment with acoramidis resulted in a sharp, significant early rise in serum TTR levels (mean 9.1 mg/dL) within 28 days which was sustained throughout the 30-month treatment period For every 5-mg/dL increase in serum TTR level, the Cox proportional hazards model predicted a relative risk reduction of mortality of 26.6% and the logistic model predicted a relative reduction of 31.6% in odds of death through Month 30 An early increase in serum TTR levels on Day 28 of dosing was associated with reduced all-cause mortality (ACM) in univariate analysis, an association which persisted in multivariate analysis independent of TTR variant status, baseline NYHA functional class, baseline NAC stage, and baseline serum TTR levels Logistic modeling demonstrated that among participants treated with acoramidis, the early increase in serum TTR was associated with reduced ACM, whereas there was no prompt and sustained increase in serum TTR observed in participants treated with placebo Causal mediation analysis showed evidence that the acoramidis treatment effect on ACM probability through month 30 was fully mediated by the observed prompt and sustained increase in serum TTR “This landmark analysis adds an incredibly important proof point to acoramidis’s repository of compelling data that higher serum TTR levels are directly correlated with and mediate a reduction in mortality risk.” said Jonathan Fox, M.D., Ph.D., Chief Medical Officer of BridgeBio Cardiorenal. “We believe that this will be an important measure for physicians treating ATTR-CM to consider and will be encouraging information for new and existing patients when reviewing options to treat their condition.” Data from 42 months sustained treatment in the open-label extension study from ATTRibute-CM showed that rapid and sustained TTR stabilization from acoramidis demonstrated statistically significant reductions in both ACM and cardiovascular-related hospitalizations (CVH, which included urgent outpatient treatment for heart failure exacerbations). The continued curve separation of the composite endpoint of ACM and CVH emphasizes the importance of early and continuous treatment resulting in early and sustained clinical benefits. These data further underscore the hypothesis that ever better levels of stabilization lead to ever better clinical outcomes and emphasizes the importance of a prognostic biomarker, serum TTR, to inform decision making for patient care.
