Milestone Pharmaceuticals Reports Third Quarter 2019 Financial Results and Provides Clinical and Corporate Update

- NODE-301 topline data readout expected in mid-1H20 -

- Richard Pasternak, M.D. appointed to the Company's Board of Directors -

MONTREAL and CHARLOTTE, N.C., Nov. 13, 2019 /PRNewswire/ -- Milestone Pharmaceuticals Inc. (Nasdaq: 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.

    --  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. Mr.
        Hasija brings to Milestone two decades of experience in corporate
        finance and business development within the healthcare industry.

Third Quarter 2019 Financial Results

    --  As of September 30, 2019, Milestone had cash, cash equivalents, and
        short-term investments of $136.5 million and 24.5 million shares
        outstanding.
    --  Research and development expense for the third quarter of 2019 was $9.5
        million compared with $3.9 million for the prior year period. For the
        nine months ended September 30, 2019, research and development expense
        was $27.8 million compared with $9.6 million for the prior year period.
        The increase in 2019 amounts reflects spending on Milestone's full Phase
        3 clinical program evaluating etripamil for the treatment of PSVT.
    --  General and administrative expenses for the third quarter of 2019 were
        $2.1 million compared with $0.6 million for the prior year period. For
        the nine months ended September 30, 2019, general and administrative
        expense was $4.7 million compared with $1.8 million for the prior year
        period. During 2019, Milestone increased its managerial headcount and,
        as a result, the related personnel costs. In addition, Milestone
        incurred increased spending for consulting fees, recruiting fees and
        professional fees, including legal and accounting services incurred to
        support its IPO.
    --  Commercial expense for the third quarter of 2019 was $2.1 million
        compared with $1.2 million for the prior year period. For the nine
        months ended September 30, 2019, commercial expense was $6.4 million
        compared with $2.3 million for the prior year period. These increases
        reflect increased commercial headcount and related costs, continued
        commercial and market research, increases in Milestone's patient
        advocacy activities and costs for its medical affairs team focused on
        key opinion leaders' engagement and disease awareness.
    --  For the third quarter of 2019, operating loss was $12.9 million compared
        to $5.7 million in 2018. For the nine months ended September 30, 2019,
        Milestone's operating loss was $37.0 million compared to $13.5 million
        in the prior year period.

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.

About Milestone Pharmaceuticals

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.
