Diagnosis of ATTRv disease will be evaluated as the primary analysis of the study - In the ACT-EARLY study, BridgeBio will partner globally with ATTR amyloidosis treating physicians and patient advocacy organizations with the hope of addressing a serious unmet need and proving that ATTRv can be delayed or prevented - 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 PALO ALTO, Calif., May 13, 2025 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a new type of biopharmaceutical company focused on genetic diseases, announced today that the first asymptomatic participant with a known pathogenic transthyretin (TTR) variant, that may lead to transthyretin amyloid disease (either cardiomyopathy, ATTR-CM, polyneuropathy, ATTR-PN, or both), has been dosed in ACT-EARLY with acoramidis. Acoramidis is a selective, small molecule, orally administered near-complete (≥90%) TTR stabilizer. “Launching ACT-EARLY is part of our ongoing commitment to further the genetic understanding of the variants causing ATTR and to ensure patients from around the world have access to optimal care. Our hope is that this study will have profound impact to patients and caregivers, and we look forward to growing our partnership with providers and patient advocacy organizations to establish a new prevention paradigm in an area where there is serious unmet need,” said Adam Castaño, M.D., Vice President of Global Clinical Development at BridgeBio Cardiorenal and Head of the ACT-EARLY clinical program. ACT-EARLY is the first ever primary prevention study for ATTR, testing the hypothesis that prophylactic treatment of asymptomatic carriers of a pathogenic TTR variant ...
