The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended acoramidis, a selective small molecule, orally administered transthyretin (TTR) stabilizer, for marketing authorization in the European Union (EU).

The compound is recommended in adult patients with transthyretin amyloid cardiomyopathy (ATTR-CM), a progressive fatal disease that presents as an infiltrative, restrictive cardiomyopathy resulting in heart failure. In vitro, acoramidis demonstrated near-complete TTR stabilization. In the Phase III study ATTRibute-CM, acoramidis has been shown clear benefits on cardiovascular endpoints.

The positive CHMP opinion for acoramidis is based on the pivotal ATTRibute-CM study results. The study investigated the efficacy and safety of acoramidis given twice daily compared to placebo, in patients with ATTR-CM.1 In the ATTRibute-CM Phase III study, acoramidis was superior to placebo in reducing the composite of all-cause mortality (ACM) and cardiovascular-related hospitalizations (CVH).

“ATTR-CM is often delayed in its recognition or is misdiagnosed, which can have a negative impact on patients’ outcomes. It is a condition that invariably progresses in the absence of treatment, and is ultimately fatal,” said Julian Gillmore, Professor of Medicine, University College London (UCL) Centre for Amyloidosis, UK. “The CHMP's positive opinion offers hope to individuals living with ATTR-CM. We are encouraged by the prospect of additional treatment, which provides near-complete stabilization of TTR, to slow the progression of symptoms and improve outcomes in patients with ATTR-CM.”

“Patients living with ATTR-CM often see a decline in their quality of life due to the physical and functional challenges posed by their condition. There is a clear need for continued innovation and further options for patients affected,” said Christine Roth, Executive Vice President, Global Product Strategy and Commercialization and Member of the Pharmaceuticals Leadership Team at Bayer. “This positive recommendation from the CHMP represents a significant milestone in the fight against this life-threatening heart disease. We eagerly anticipate the European Medicines Agency's approval for acoramidis, expected in early 2025 and are striving to make this new treatment available to patients as soon as possible.”

The final decision from the European Commission on the marketing authorization is expected in the coming months. Acoramidis, developed by BridgeBio Pharma, Inc. (Nasdaq: BBIO), was recently approved by the Food and Drug Administration (FDA) for the U.S. with a label specifying near-complete stabilization of TTR.3 BridgeBio holds the marketing rights for acoramidis in the U.S., while Bayer holds the exclusive marketing rights for the product in Europe. Pending approval, Bayer plans to launch acoramidis in Europe in the first half of 2025.

Since March 2024, Bayer and BridgeBio and affiliates, have pursued a collaboration for acoramidis. 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.
