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.

“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.
