BridgeBio Pharma Presents Cardiac Magnetic Resonance (CMR) Imaging Evidence Consistent with Clinical Improvement Observed in the ATTRibute-CM Phase 3 Study in Patients with Transthyretin Amyloid Cardiomyopathy (ATTR-CM)

- In this exploratory substudy, treatment with acoramidis was associated with possible cardiac structural and functional improvement compared with placebo, with potential cardiac amyloid regression

- The data demonstrate that targeting near-complete transthyretin (TTR) stabilization with acoramidis may enable cardiac remodeling and functional recovery in patients with ATTR-CM

- These results are the first prospective, longitudinal evaluation of cardiac structure and function by CMR imaging in a double-blind, placebo-controlled, interventional study in ATTR-CM

- The findings from this study build upon positive results from BridgeBio’s global ATTRibute-CM Phase 3 trial, wherein the primary endpoint was met (Win Ratio of 1.8) with a high statistical significance (p<0.0001); the substudy data are consistent with the cardiovascular clinical benefits observed with acoramidis

- Acoramidis was well-tolerated, with no safety signals of potential clinical concern observed

- BridgeBio’s New Drug Application (NDA) has been accepted by the U.S. Food and Drug Administration (FDA) with a PDUFA action date of November 29, 2024; a Marketing Authorization Application (MAA) for acoramidis has been accepted by the European Medicines Agency (EMA), with an expected decision in 2025

PALO ALTO, Calif., April 07, 2024 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a commercial-stage biopharmaceutical company focused on genetic diseases and cancers, today presented results from the exploratory CMR imaging substudy of ATTRibute-CM, its Phase 3 trial of acoramidis in ATTR-CM. These data were presented at the American College of Cardiology (ACC) Annual Scientific Sessions & Expo in a moderated poster session by Yousef Razvi, M.D. of University College London. 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. Based on the positive results from ATTRibute-CM, BridgeBio submitted an NDA to the U.S. FDA, which has been accepted with a PDUFA action date of November 29, 2024, and an MAA to the European Medicines Agency, with a decision expected in 2025.
