About Interventional Cardiology Medical Group (ICMG) Founded nearly 40 years ago, ICMG’s community-based cardiology team of physicians, nurse practitioners, sonographers, radiation technologists, research staff and patient care coordinators have distinguished itself as the preeminent cardiology practice in the West Valley area (suburban Los Angeles, CA). About Paroxysmal Supraventricular Tachycardia An estimated two million people in the United States are currently diagnosed with PSVT which is a type of arrhythmia or abnormal heart rhythm. PSVT is characterized by episodes of sudden onset rapid heartbeats often exceeding 150 to 200 beats per minute. The heart rate spike is unpredictable and may last several hours. The rapid heart rate often causes disabling severe palpitations, shortness of breath, chest discomfort, dizziness or lightheadedness, and distress, forcing patients to limit their daily activities. The uncertainty of when an episode of PSVT will strike or how long it will persist can provoke anxiety in patients and negatively impact their day-to-day life between episodes. The impact and morbidity from an attack can be especially detrimental in patients with underlying cardiovascular or medical conditions, such as heart failure, obstructive coronary disease, or dehydration. Many health care providers are dissatisfied with the lack of effective treatment options with patients often requiring prolonged, burdensome, and costly trips to the emergency department or even invasive cardiac ablation procedures. About Atrial Fibrillation with Rapid Ventricular Rate An estimated five million Americans suffer from atrial fibrillation (AFib), a common arrhythmia marked by an irregular, disruptive and often rapid heartbeat. The incidence of AFib is expected to grow to approximately 10 million by 2025 and up to about 12 million by 2030. A subset of patients with AFib experience episodes of abnormally high heart rate most often accompanied by palpitations, shortness of breath, dizziness, and weakness. While these episodes, known as AFib-RVR, may be treated by oral calcium channel blockers and/or beta blockers, patients frequently seek acute care in the emergency department to address symptoms. In 2016, nearly 800,000 patients were admitted to the emergency department due to AFib symptoms where treatment includes medically supervised intravenous administration of calcium channel blockers or beta blockers, or electrical cardioversion. With little available data for AFib-RVR, Milestone's initial market research indicates that 30 to 40% of patients with AFib experience one or more symptomatic episodes of RVR per year that require treatment, suggesting a target addressable market of approximately three to four million patients in 2030 for etripamil in patients with AFib-RVR. About Etripamil Etripamil is Milestone's lead investigational product. It is a novel calcium channel blocker nasal spray under clinical development for frequent and often highly symptomatic episodes of PSVT and atrial fibrillation with rapid ventricular rate (AFib-RVR). It is designed as a self-administered rapid response therapy for patients thereby bypassing the need for immediate medical oversight. If approved, etripamil is intended to provide health care providers with a new treatment option to enable on-demand care and patient self-management. This portable, self-administered treatment may provide patients with active management and a greater sense of control over their condition. CARDAMYST™ (etripamil) nasal spray, the conditionally approved brand name for etripamil nasal spray, is well studied with a robust clinical trial program that includes a completed Phase 3 clinical-stage program for the treatment of PSVT and Phase 2 trial for the treatment of patients with AFib-RVR. About Milestone Pharmaceuticals Milestone Pharmaceuticals Inc. (Nasdaq: MIST) is a biopharmaceutical company developing and commercializing innovative cardiovascular solutions to improve the lives of people living with complex and life-altering heart conditions. The Company’s focus on understanding unmet patient needs and improving the patient experience has led us to develop new treatment approaches that provide patients with an active role in self-managing their care. Milestone’s lead investigational product is etripamil, a novel calcium channel blocker nasal spray that is being studied for patients to self-administer without medical supervision to treat symptomatic episodic attacks associated with PSVT and AFib-RVR.

Sept. 06, 2024 -- Milestone® Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced its licensing partner, Ji Xing Pharmaceuticals Ltd, released positive topline results from a multi-center, randomized, double-blind, placebo-controlled trial in China evaluating the efficacy and safety of etripamil nasal spray in paroxysmal supraventricular tachycardia (PSVT). The trial design closely matched the RAPID Phase 3 Study of etripamil in PSVT conducted by Milestone in North America and Europe. The 500-patient Phase 3 trial (JX02002) met its primary endpoint, with a Kaplan Meier analysis shows a statistically significantly greater proportion of patients who self-administered etripamil converted from PSVT to sinus rhythm within 30 minutes compared to placebo (40.5% vs. 15.9%, respectively; hazard ratio [HR] = 3.00; 95% CI 1.58-5.71; p<0.001). Statistically significant (p<0.05) results were also shown for the secondary efficacy endpoints for percent of patients’ PSVT converted to sinus rhythm by 10, 15, 45, and 60 minutes after self-administration of study drug. Ji Xing further reported that, overall, treatment emergent adverse events were comparable between treatment groups, and there were no reported serious adverse events related to etripamil. The safety and tolerability data from the JX02002 trial were consistent with previous clinical studies. This important study further expands the etripamil global development program to more than 2,000 unique patients treated with etripamil. "Congratulations to Ji Xing and all the clinical investigators on the successful completion of this large Phase 3 study of etripamil in PSVT," said Joseph Oliveto, President and Chief Executive Officer of Milestone Pharmaceuticals. "We are proud to partner with our colleagues at Ji Xing as they advance etripamil toward regulatory approval in China, with the potential to help millions of patients struggling with PSVT." Under the terms of the license agreement announced on May 21, 2021, Milestone granted Ji Xing an exclusive license to develop and, if regulatory approval is obtained, commercialize etripamil in patients with PSVT in Greater China. Milestone received an upfront cash payment consisting of $15 million along with a $5 million equity investment by RTW Investments, LP. In addition, Milestone remains eligible to receive up to $107.5 million in milestone payments and royalties on future sales of etripamil in Greater China (including Mainland China, Hong Kong, Macau & Taiwan). Milestone supplies etripamil and delivery devices to Ji Xing. Ji Xing is responsible for development and commercialization costs in Greater China.
