- In participants who switched from tafamidis and placebo in the ATTRibute-CM study to acoramidis in its open-label extension (OLE), there was a mean of 3.0mg/dL increase in serum transthyretin (TTR) at Month 1 of the OLE (n=21) and mean of 3.4mg/dL increase in serum TTR at Month 6 of the OLE (n=18)
-Increased serum TTR at Day 28 of ATTRibute-CM was correlated with reduced risk of all-cause mortality (ACM), cardiovascular mortality (CVM), and cardiovascular-related hospitalization (CVH) in transthyretin amyloid cardiomyopathy (ATTR-CM)
-Greater stabilization has been shown to improve clinical outcomes for patients, and in ATTRibute-CM, acoramidis, a near-complete stabilizer of TTR, demonstrated a significant impact on mortality, hospitalizations, and quality of life including:
PALO ALTO, Calif., Aug. 30, 2024 (GLOBE NEWSWIRE) - BridgeBio Pharma, Inc. (Nasdaq: BBIO) ("BridgeBio" or the "Company"), a commercial-stage biopharmaceutical company focused on genetic diseases, presented additional data from an analysis of its Phase 3 ATTRibute-CM and open-label extension study of acoramidis in ATTR-CM at the European Society of Cardiology (ESC) 2024. ATTRibute-CM was designed to study the efficacy and safety of acoramidis, an investigational, next-generation, orally-administered, highly potent, small molecule stabilizer of TTR.
The data on change from baseline in serum TTR levels in participants receiving acoramidis versus those receiving tafamidis in the placebo group in ATTRibute-CM at Month 30, as well as serum TTR levels in patients who transitioned from placebo and tafamidis to acoramidis in the OLE study, were presented by Mathew Maurer, M.D. of Columbia University Irving Medical Center. In participants who switched from tafamidis and placebo in the ATTRibute-CM study to acoramidis in its OLE, there was a mean of 3.0mg/dL increase in serum TTR at Month 1 of the OLE (n=21, p=0.01) and mean of 3.4mg/dL increase in serum TTR at Month 6 of the OLE (n=18, p=0.01).
TTR plays an important role in the body transporting thyroxine and vitamin A, and higher TTR levels are associated with less heart failure and better survival. BridgeBio previously shared results demonstrating that acoramidis treatment resulted in increased serum TTR levels by Day 28 that were sustained and were correlated with a reduced risk of ACM, CVM, and CVH in ATTR-CM participants through Month 30. This includes the following results:
"The data shared show that switching from tafamidis to acoramidis resulted in an increase in serum TTR, which has been associated with improved outcomes in patients with ATTR-CM," said Dr. Maurer. "In a future arena of multiple disease modifying therapies for ATTR-CM, such data may provide a rationale for monitoring of patients with serum transthyretin levels and using these data in choosing a specific treatment."
Additionally, as part of the ongoing partnership with the Cardiovascular Data Science (CarDS) Lab, Rohan Khera, M.D., M.S., cardiologist-data scientist at Yale School of Medicine will be presenting about the artificial intelligence tools being deployed in the TRACE AI Network Study. The BridgeBio-partnered initiative will provide a scalable screening toolkit for ATTR-CM across large, diverse health systems to quantify the potential prevalence of undiagnosed ATTR-CM among all patients undergoing routine cardiovascular evaluation, specifically among key socioeconomic and demographic subpopulations.
Based on the positive results from ATTRibute-CM, BridgeBio submitted a New Drug Application to the U.S. Food and Drug Administration, which has been accepted with a PDUFA action date of November 29, 2024, and a Marketing Authorization Application to the European Medicines Agency, with a decision expected in 2025. BridgeBio has granted exclusive rights to Bayer to commercialize acoramidis for ATTR-CM in Europe.

BridgeBio and Bayer European License for Acoramidis - About the Collaboration
In March 2024, BridgeBio granted Bayer exclusive license to commercialize acoramidis as a treatment for patients with transthyretin amyloid cardiomyopathy (ATTR-CM) in Europe. Acoramidis is an investigational, highly potent and selective small molecule, under development as an orally administered transthyretin (TTR) stabilizer for the treatment of patients with ATTR-CM a progressive fatal disease presenting as an infiltrative, restrictive cardiomyopathy resulting in heart failure.
This partnership leverages Bayer's long legacy of expertise in cardiovascular disease and its established European cardiovascular infrastructure paired with BridgeBio's leadership in the emerging field of ATTR-CM.
BridgeBio Forward Looking Statements
This press release contains forward-looking statements. Statements in this press release may include statements that are not historical facts and are considered forward-looking within the meaning of Section 27A of the Securities Act of 1933, as amended (the Securities Act), and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act), which are usually identified by the use of words such as "anticipates," "believes," "continues," "estimates," "expects," "hopes," "intends," "may," "plans," "projects," "remains," "seeks," "should," "will," and variations of such words or similar expressions.
