Open-Label Extension Data Confirms Sustained Benefit of Acoramidis on Cardiovascular Outcomes, Including Statistically Significant Reduction in ACM Within 36 Months

PALO ALTO, Calif., Nov. 18, 2024 (GLOBE NEWSWIRE) — BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a new type of biopharmaceutical company focused on genetic diseases, presented positive initial outcomes from the ATTRibute-CM open-label extension (OLE) study of acoramidis in ATTR-CM at the American Heart Association (AHA) Scientific Sessions. ATTRibute-CM was designed to evaluate the efficacy and safety of acoramidis, an investigational, near-complete, orally-administered, small molecule stabilizer of TTR. The preliminary results from this ongoing OLE study were also simultaneously published in Circulation. The OLE study involves 389 participants who completed the 30-month ATTRibute-CM Phase 3 study.

“Results from the ATTRibute-CM OLE continue to showcase the potential of acoramidis, with ongoing data across the study suggesting that early intervention with this stabilizer leads to early separation from placebo, with sustained benefit for patients with ATTR-CM,” said Daniel Judge, M.D., professor of medicine and cardiology at the Medical University of South Carolina. “The prescribing community is eager to have another important treatment option given the remaining high unmet need for ATTR-CM patients.”

Key initial results from the OLE study, presented by Dr. Judge at AHA, show that continuous treatment with acoramidis led to:

  • A confirmed sustained improvement relative to placebo in time to first event (CVH or ACM) starting at Month 3 in ATTRibute-CM
  • A statistically significant reduction in ACM alone of 36% by Month 36 (p=0.009) and 34% by Month 42 (p=0.006), as assessed by the Stratified Cox proportional hazards model
  • A significant reduction of composite ACM and CVH by 46% at Month 36 (p<0.0001) and 48% at Month 42 (p<0.0001), as assessed by negative binomial regression, building upon the previously presented 42% reduction at Month 30 in ATTRibute-CM
  • Evidence of early benefit in patients who crossed over from placebo to acoramidis after Month 30 as compared to extrapolated placebo curve reinforces the early separation seen previously in ATTRibute-CM
  • Acoramidis continues to be well tolerated, with no new clinically significant safety signals identified in this long-term evaluation

    • The OLE data build on previously reported results from ATTRibute-CM in which acoramidis demonstrated clinically important treatment effects on mortality, CVH, and quality of life, further supporting that greater transthyretin (TTR) stabilization can improve clinical outcomes for patients. This included a 50% reduction in the cumulative frequency of CVH relative to placebo at Month 30.

    “We are pleased to share the initial results from the ongoing open-label extension study of ATTRibute-CM, which showcase the sustained benefits of acoramidis treatment for patients with ATTR-CM,” said Jonathan Fox, M.D., Ph.D., chief medical officer of BridgeBio Cardiorenal. “Coupled with acoramidis’ earliest time to separation of any known ATTR-CM treatment on clinical outcomes at 3 months, these analyses continue to support acoramidis as a meaningful first line option.”

    In addition to the featured science oral presentation at AHA, BridgeBio also shared three moderated posters:

  • Costs and Healthcare Resource Utilization in Transthyretin Amyloid Cardiomyopathy Exceeds That of Generalized Heart Failure
  • Evolving Baseline Risk in Patients with Transthyretin Amyloid Cardiomyopathy: A Systematic Literature Review of Clinical Trials
  • Acoramidis Improved Survival in Patients with Transthyretin Cardiac Amyloidosis Regardless of Prior Cardiovascular Hospitalization

    • These findings reinforce the importance of an effective therapy that reduces CVH and improves survival in patients with ATTR-CM.

    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.
