MONTREAL and CHARLOTTE, N.C., March 20, 2025 (GLOBE NEWSWIRE) -- Milestone^® Pharmaceuticals Inc. (Nasdaq: MIST) a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced that it will present a moderated poster presentation at the American College of Cardiology annual meeting (ACC25), to be held March 29^th to 31^st, 2025 in Chicago, Illinois.

“This presentation highlights the potential ability of etripamil to successfully convert multiple episodes of Paroxysmal Supraventricular Tachycardia (PSVT) to restore normal sinus rhythm. Further, the data showed that conversion of earlier episodes was predictive of conversion in subsequent ones,” said David Bharucha, MD PhD FACC, Chief Medical Officer of Milestone Pharmaceuticals. “These new data support the opportunity to use etripamil, if approved, for successive PSVT episodes underscoring a potentially positive impact on patients’ experience and quality of life, in line with Milestone’s commitment to providing a convenient and effective therapeutic option for PSVT.”

A copy of the abstract can be viewed on the ACC25 website, on the Online Planner here.
