Milestone Pharmaceuticals Reports Third Quarter 2020 Financial Results and Provides Clinical and Corporate Update

MONTREAL and CHARLOTTE, N.C., Nov. 13, 2020 /PRNewswire/ -- Milestone Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today reported financial results for the third quarter ended September 30, 2020 and provided a clinical and corporate update.

"We remain on track to reopen enrollment in the pivotal Phase 3 RAPID trial by year-end, and are confident that the updated study design will help us to best characterize the potential clinical utility of our product candidate etripamil in patients with paroxysmal supraventricular tachycardia (PSVT)," said Joseph Oliveto, President and Chief Executive Officer of Milestone Pharmaceuticals. "In light of the safety and efficacy data from the completed NODE-301 trial, as well as positive feedback from the physicians charged with treating patients with PSVT, we believe that etripamil has the potential to serve as a much needed at-home intervention for this population. Backed by a strong balance sheet, which includes gross proceeds of $51.7 million from our recent public offering, we look forward to continuing to execute the etripamil PSVT program, with the goal of bringing this investigational therapy to as many appropriate patients as possible if approved by the FDA."

Recent Updates

    --  Pivotal Phase 3 RAPID Trial on Track to Reopen by Year-End. The Company
        remains on track to reopen enrollment in the pivotal Phase 3 RAPID trial
        by the end of the year. The RAPID trial is expected to randomize up to
        500 patients and will be completed after a total of 180 confirmed
        supraventricular tachycardia (SVT) events are reached. Patients in the
        RAPID trial will be randomized 1:1 to etripamil or placebo. To help
        maximize the potential treatment effect of etripamil, patients who do
        not experience symptom relief within 10 minutes of the first study drug
        administration will be directed to administer a second dose of study
        drug. As previously announced, the primary efficacy endpoint for both
        the RAPID trial and the already-completed NODE-301 trial will be time to
        conversion of SVT within 30 minutes following initial study drug
        administration, with a target p-value of less than 0.05 for each trial.
        Milestone expects to report data from the RAPID trial in late 2021/early
        2022. The RAPID and completed NODE-301 trials could potentially serve to
        fulfill the efficacy requirement for a future New Drug Application (NDA)
        for etripamil in patients with PSVT.
    --  Raised $51.7 Million in Public Offering. In October 2020, Milestone
        announced the closing of an underwritten public offering of 5,095,897 of
        its common shares and, to certain investors in lieu thereof, pre-funded
        warrants to purchase 4,761,903 of its common shares at an exercise price
        of $0.01 per share. The public offering price of each common share was
        $5.25 and the public offering price of each pre-funded warrant was $5.24
        per underlying share. Total gross proceeds to Milestone were
        approximately $51.7 million before deducting underwriting discounts and
        offering expenses.
    --  Recent Changes to Board of Directors. In September 2020, Milestone
        announced the appointment of highly accomplished industry veterans Lisa
        Giles and Robert Wills to its Board of Directors. In addition, the
        Company today announced that Dr. Wills will replace Paul R. Edick as
        Chairman of the Board of Directors. Mr. Edick will be stepping down from
        the Board, effective January 1, 2021, to focus on his role as Chief
        Executive Officer at Xeris Pharmaceuticals and their recent product
        launch.

Mr. Oliveto added, "On behalf of the entire Board of Directors, I would like to thank Paul for his insights and contributions over the last two years. We wish him the very best of luck in all of his future endeavors."

Third Quarter 2020 Financial Results

    --  As of September 30, 2020, Milestone had cash, cash equivalents, and
        short-term investments of $102.9 million, 24.7 million shares
        outstanding and 6.7 million pre-funded warrants outstanding.
    --  Research and development expenses for the third quarter of 2020 were
        $8.2 million compared with $9.5 million for the prior year period. For
        the nine months ended September 30, 2020, research and development
        expenses were $28.7 million compared with $27.8 million for the prior
        year period. The increase for the nine-month period ending September 30,
        2020 reflects increased clinical development costs supporting
        Milestone's Phase 3 clinical trials and efforts in developing a clinical
        trial pathway for etripamil.
    --  General and administrative expenses for the third quarter of 2020 were
        $3.0 million compared with $2.1 million for the prior year period. For
        the nine months ended September 30, 2020, general and administrative
        expenses were $8.6 million compared with $4.7 million for the prior year
        period. The increase in the nine-month period ending September 30, 2020
        reflects increasing insurance costs, as well as additional professional
        fees and head count to support the compliance requirements of being a
        public company.
    --  Commercial expenses for the third quarter of 2020 were $0.9 million
        compared with $2.1 million for the prior year period. For the nine
        months ended September 30, 2020, commercial expense was $4.6 million
        compared with $6.4 million for the prior year period. The decrease in
        expenses in the nine-month period ending September 30, 2020 reflects
        efforts in reducing operating expenses affecting primarily
        pre-commercialization activities as Milestone focused its efforts on an
        optimized clinical development pathway for etripamil.
    --  For the third quarter of 2020, operating loss was $12.1 million compared
        to $13.7 million in 2019. For the nine months ended September 30, 2020,
        Milestone's operating loss was $41.9 million compared to $39.0 million
        in the prior year period.

About Paroxysmal Supraventricular Tachycardia

PSVT is a rapid heart rate condition characterized by intermittent episodes of SVT that start and stop suddenly and without warning. Episodes of SVT are often associated with symptoms including palpitations, sweating, chest pressure or pain, shortness of breath, sudden onset of fatigue, lightheadedness or dizziness, fainting, and anxiety. Certain calcium channel blockers have long been approved for the treatment of PSVT as well as other cardiac conditions. However, calcium channel blockers approved for the termination of SVT episodes must be administered intravenously under medical supervision, usually in an emergency department or other acute care setting.

About Etripamil

Etripamil, the Company's lead investigational product, is designed to be a rapid-response therapy for episodic cardiovascular conditions. The novel calcium channel blocker is self-administered via a nasal spray, which has the potential to shift the current treatment paradigm for many patients with PSVT from the emergency department to the at-home setting. Milestone is conducting a comprehensive development program for etripamil, with Phase 3 trials underway in PSVT, and plans to commence a Phase 2 proof-of-concept trial in patients with atrial fibrillation with rapid ventricular rate.
