PhaseBio Announces Bentracimab Phase 2b Trial Data Accepted for Late Breaking Clinical Research Presentation at the 2022 American College of Cardiology (ACC.22) Annual Scientific Session
MALVERN, PA & SAN DIEGO--(BUSINESS WIRE)-- PhaseBio Pharmaceuticals, Inc. (Nasdaq: PHAS), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapies for cardiopulmonary diseases, today announced that the Phase 2b trial of bentracimab, which was conducted in healthy, older volunteers 50-80 years old, has been accepted for presentation in a Late Breaking Clinical Research session at the American College of Cardiology Annual Scientific Session & Expo being held in Washington, D.C., April 2-4, 2022. The Phase 2b trial is a multi-center, randomized, double-blind, placebo-controlled study with 150 subjects receiving bentracimab and 50 subjects receiving placebo after all were pretreated with dual antiplatelet therapy composed of ticagrelor and low-dose aspirin. Top-line results from the Phase 2b trial were previously announced in November 2021.
- Title: Bentracimab Immediately and Significantly Reverses the Antiplatelet Effects of Ticagrelor in Older People
- Presenting Author: Deepak L. Bhatt, M.D., MPH, Executive Director of Interventional Cardiovascular Programs, Brigham and Women's Hospital and Professor of Medicine at Harvard Medical School
- Session Title: Featured Clinical Research I
- Session Number: 403-10
- Date: April 2, 2022
- Session Time: 12:00 pm – 1:15 pm ET
- Presentation Time: 12:15 pm – 12:25 pm ET
“As part of the pivotal development program for bentracimab, which also includes the Phase 3 REVERSE-IT trial, the Phase 2b trial was designed to help answer important safety and efficacy questions related to bentracimab use in older subjects pre-treated with ticagrelor and aspirin therapy,” said John Lee, M.D., Ph.D., Chief Medical Officer of PhaseBio. “We are pleased to have the opportunity to present the results from this trial to key stakeholders in the cardiology community at a high-profile medical congress like ACC.22.”
REVERSE-IT is a Phase 3, multi-center, open-label, prospective single-arm trial designed to study reversal of the antiplatelet effects of ticagrelor with bentracimab in patients who present with uncontrolled major or life-threatening bleeding or who require surgery or invasive procedure. Approximately 200 patients are being targeted to be enrolled from major health centers worldwide. In November 2021, PhaseBio presented interim results from the REVERSE-IT trial during a Late-Breaking Science Session at the 2021 American Heart Association Scientific Sessions. In December 2021, the REVERSE-IT interim results were subsequently published in NEJM Evidence, a new digital journal from the NEJM (New England Journal of Medicine) Group. The Company is commencing preparation of the BLA and targeting a BLA submission to the U.S. Food and Drug Administration (FDA) in mid-2022.
Bentracimab has been studied in Phase 1 and Phase 2 clinical trials and has demonstrated the potential to bring life-saving therapeutic benefit through immediate and sustained reversal of the antiplatelet activity of ticagrelor, potentially mitigating concerns regarding bleeding risks associated with the use of this antiplatelet drug. Additionally, in a translational study, bentracimab achieved equivalent reversal of branded ticagrelor and multiple ticagrelor generics.
About Bentracimab (PB2452)
Bentracimab is a novel, recombinant, human monoclonal antibody antigen-binding fragment designed to reverse the antiplatelet activity of ticagrelor in major bleeding and urgent surgery situations. In a Phase 1 clinical trial, bentracimab demonstrated the potential to bring life-saving therapeutic benefit through immediate and sustained reversal of ticagrelor’s antiplatelet activity, mitigating concerns regarding bleeding risks associated with the use of this antiplatelet drug. Data from the Phase 1 clinical trial of bentracimab in healthy volunteers was published in the New England Journal of Medicine in March 2019. In April 2019, bentracimab received Breakthrough Therapy Designation from the FDA. In September 2019, PhaseBio completed a Phase 2a trial in which bentracimab was investigated in healthy, older subjects on dual antiplatelet therapy of ticagrelor and low-dose aspirin. Additionally, the Phase 2a trial investigated a bentracimab regimen for the reversal of supratherapeutic doses of ticagrelor in healthy younger subjects. In November 2021, PhaseBio completed a Phase 2b trial in which bentracimab was investigated in healthy, older subjects on dual antiplatelet therapy of ticagrelor and low-dose aspirin. In all active treatment arms in both the Phase 2a and Phase 2b trials, bentracimab achieved immediate and sustained reversal of the antiplatelet effects of ticagrelor and was generally well-tolerated, with only minor adverse events reported. These results are consistent with the results observed in healthy younger subjects treated with ticagrelor in the previously published Phase 1 trial. PhaseBio initiated REVERSE-IT, a pivotal Phase 3 clinical trial of bentracimab, in March 2020 to support a potential Biologics License Application for bentracimab in both major bleeding and urgent surgery indications. Interim results from the Phase 3 REVERSE-IT trial were presented in November 2021 and subsequently published in NEJM Evidence in December 2021.
