MONTREAL and CHARLOTTE, N.C., Nov. 13, 2019 /PRNewswire/ -- Milestone Pharmaceuticals Inc. MIST, a Phase 3 clinical-stage biopharmaceutical company dedicated to developing and commercializing etripamil for the treatment of cardiovascular indications, today reported financial results for the third quarter ended September 30, 2019 and provided a clinical and corporate update.

"Thanks to the hard work of our study team, a dedicated group of clinical sites, and, importantly, the patients participating in our study, NODE-301 continues to exceed our enrollment and PSVT event rate expectations, with topline data now expected in the middle of the first half of 2020," said Joseph Oliveto, President and Chief Executive Officer of Milestone Pharmaceuticals. "In addition, progress continues with efforts to ramp up our recently initiated global safety study, NODE-303, the largest study ever conducted in PSVT."

Mr. Oliveto added, "I am honored to welcome Dr. Richard Pasternak to our Board of Directors. A cardiologist by training, he brings a wealth of cardiovascular drug development experience that incorporates academia, large pharma and small entrepreneurial companies."

NODE-301 Update

Milestone today announced that it now expects to report topline data for the NODE-301 trial in the middle of the first half of 2020. The NODE-301 trial is a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial of etripamil, the Company's novel short-acting calcium channel blocker, for terminating paroxysmal supraventricular tachycardia (PSVT) episodes in the outpatient setting. The study is designed to treat an enriched population of those PSVT patients who historically experience 20 minutes or longer PSVT episodes or episodes requiring termination in the emergency department.  The primary endpoint of the NODE-301 study is time to conversion of PSVT to sinus rhythm after the administration of study drug, as confirmed by a central independent adjudication committee. Secondary study endpoints include relief of symptoms commonly associated with an episode of PSVT such as heart palpitations, chest pain, anxiety, shortness of breath, dizziness, or fainting, and rating of treatment satisfaction questionnaire for medication (TSQM).

As previously announced, after the NODE-301 trial reaches its target number of adjudicated PSVT events, collection of blinded data from randomized patients who have not yet experienced an event will continue. These data will be analyzed separately as a secondary data set, referred to as NODE-301B, and may contribute further to sub-population analyses and pharmacoeconomic assessments.

He received his B.A. and M.D. from Yale University, and completed his medical and cardiology training at Massachusetts General Hospital.
• Company to Commence Clinical Evaluation of Etripamil in Atrial Fibrillation with Rapid Ventricular Rate (RVR). In 2020, Milestone plans to initiate a proof-of-concept clinical trial of etripamil for the treatment of patients with atrial fibrillation with RVR, another type of supraventricular tachycardia in which most patients experience episodes of elevated heart rates and for which L-type calcium channel blockers are approved for rate control.
• Enrolled First Patient in NODE-303 Study. In October 2019, Milestone announced enrollment of the first patient in the Company's Phase 3 open-label, global safety study of etripamil in patients with PSVT. The study will primarily evaluate the safety of etripamil when self-administered without medical supervision during single or multiple PSVT episodes. Important secondary measures include efficacy, patient quality of life and pharmacoeconomic assessments. The study represents the largest study ever conducted in PSVT, assessing up to 1,500 patient episodes from patients who did not participate in NODE-301 or its open-label safety extension study, NODE-302.
• Announced Appointment of Amit Hasija as Chief Financial Officer and Executive Vice President of Corporate Development. In September 2019, the Company announced the appointment of Amit Hasija as Chief Financial Officer and Executive Vice President of Corporate Development.

About Etripamil in Paroxysmal Supraventricular Tachycardia

Paroxysmal Supraventricular Tachycardia (PSVT) is a rapid heart rate condition that starts and stops without warning, often experienced by patients with symptoms including palpitations, sweating, chest pressure or pain, shortness of breath, sudden onset of fatigue, lightheadedness or dizziness, fainting and anxiety. Calcium channel blockers have long been approved for the treatment of PSVT as well as other cardiac conditions, however, for episodes of PSVT calcium channel blockers are currently administered intravenously under medical supervision, usually in the emergency department. By contrast, etripamil is designed to serve as a self-administered therapy for the rapid termination of episodes of PSVT. With its combination of convenient delivery, rapid onset and short duration of action, etripamil has the potential to shift the current treatment paradigm for PSVT away from the burdensome and costly emergency department settings by treating episodes of PSVT wherever and whenever they occur.

Milestone is a Phase 3 clinical-stage biopharmaceutical company dedicated to developing and commercializing the investigational new drug etripamil for the treatment of cardiovascular indications. Milestone is actively recruiting patients for a Phase 3 clinical trial of etripamil for the treatment of PSVT. Milestone plans to initiate a Phase 2 clinical trial in atrial fibrillation, another rapid heart rate condition, and expects to subsequently initiate an additional Phase 2 clinical trial in angina to establish proof-of-concept for the broader use of etripamil.
