Recent Program Updates
Etripamil for PSVT
- NDA Submission for Etripamil Nasal Spray in Patients with PSVT Currently on Track for the Third Quarter of 2023. In March 2023, Milestone announced completion and database closures of the NODE-303 open-label safety and RAPID extension studies of etripamil, the Company's investigational calcium channel blocker that is administered by patients outside of the healthcare setting, in patients with PSVT. Data from these studies are being included in the PSVT NDA for etripamil which is currently expected to be submitted to the FDA in the third quarter of 2023. The Company believes feedback received from the FDA supports the proposed approach for the NDA.
- Data Highlighting Decreased Emergency Department (ED) Utilization in Patients with PSVT Treated with Etripamil Featured at the Professional Society for Health Economics and Outcomes Research (ISPOR) Annual Meeting. In May 2023, data highlighting decreased ED utilization in patients treated with etripamil in the Phase 3 NODE-301 Part 1 and RAPID studies were featured during a poster session at the ISPOR Annual Meeting. The previously presented data showed that relative to placebo, etripamil was associated with a significant reduction in use of the ED for medical intervention (14% of etripamil patients vs. 22% of placebo patients in the prespecified RAPID and NODE-301 Part 1 pooled analysis), reflecting a 39% relative risk reduction.
Etripamil for AFib-RVR
- Data from a Subset of Patients with AFib-RVR to be Presented at Heart Rhythm 2023 Annual Meeting. Data from a subset of patients with AFib-RVR in the NODE-303 study, which evaluated etripamil in patients with PSVT, will be featured during an oral session at the Heart Rhythm 2023 Annual Meeting: "Effect of Etripamil Nasal Spray on Ventricular Rate in Patients Experiencing Symptomatic Atrial Fibrillation," on Friday, May 19, 2023 at 3:00 p.m. CT .
- Company to Host Virtual Key Opinion Leader Event on Etripamil for the Treatment of AFib-RVR. Milestone will host a virtual KOL event on Monday, May 22, 2023 at 8:00 a.m. ET to discuss etripamil for the potential treatment of patients with AFib-RVR. The event will feature a review of data being featured at the upcoming Heart Rhythm 2023 Annual Meeting, an overview of AFib-RVR, including the current treatment landscape and etripamil characteristics, and commentary on next steps for the etripamil development program in this potential indication.

- Topline data from ReVeRA Phase 2 Proof-of-Concept Trial in Patients with AFib-RVR Expected in the Second Half of 2023. Enrollment continues in ReVeRA, Milestone's Phase 2 double-blind, placebo-controlled, proof-of-concept trial of etripamil nasal spray in emergency-department patients experiencing AFib-RVR. The trial, in which patients are randomized 1:1 to receive either 70 mg of etripamil or placebo, is designed to assess the safety and efficacy of etripamil nasal spray to reduce elevated ventricular rates in patients with symptomatic AFib-RVR. The primary endpoint will assess reduction in ventricular rate, with key secondary endpoints including the time to achieve the maximum reduction in rate and duration of the effect. Milestone expects to report topline data from this trial in the second half of 2023.
Recent Corporate Updates
- Announced $125 Million Strategic Financing with RTW Investments to Support the Advancement of Etripamil for PSVT. In March 2023, Milestone announced that it entered into a $125 million strategic financing with existing shareholder, RTW Investments, LP and certain of its affiliates ("RTW"). RTW has extended its investment relationship with Milestone by purchasing $50 million of senior secured convertible promissory notes in a private placement transaction. In addition, under the terms of a purchase and sale agreement, following FDA approval of etripamil and subject to certain conditions, RTW provided a $75 million non-dilutive synthetic royalty financing commitment to Milestone in return for tiered rate, cash royalty payments based on aggregate net sales of etripamil within the United States .
- Seth H.Z. Fischer Appointed to Board of Directors. In March 2023, Milestone appointed Seth H.Z. Fischer to the Company's Board of Directors.

About Paroxysmal Supraventricular Tachycardia
Paroxysmal Supraventricular Tachycardia (PSVT) is a highly symptomatic and impactful heart arrhythmia characterized by unpredictable attacks of a racing heart that afflicts approximately two million Americans. Symptoms of PSVT, including palpitations, chest pressure, and shortness of breath are often debilitating, causing the patient to stop their current activities or avoid pursuits altogether. 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. The uncertainty of when an episode of SVT will strike or how long it will persist can provoke anxiety in patients, which can have a negative impact on their day-to-day life. Many doctors are unsatisfied by the lack of effective treatment options besides a prolonged, unpleasant, and costly trip to the emergency department or, for some patients, an invasive ablation procedure.
About Atrial Fibrillation with Rapid Ventricular Rate
Atrial fibrillation (AFib) is a common arrhythmia marked by an irregular and often rapid heartbeat. AFib is estimated to affect five million patients in the United States, a prevalence projected by the Centers for Disease Control to increase to twelve million patients by 2030. Atrial fibrillation with rapid ventricular rate (AFib-RVR) is a condition that many patients with AFib experience and includes episodes of abnormally high heart rate, often with symptoms of palpitations, shortness of breath, dizziness, and weakness. Oral calcium channel blockers and/or beta blockers are used to reduce the heart rate in this condition. When AFib-RVR occurs, symptoms are often burdensome enough to cause patients to seek acute care in the emergency department, where standard-of-care procedures include intravenous administration of calcium channel blockers or beta blockers, or electrical cardioversion, under medical supervision. Milestone's initial market research indicates that 30-40% 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.
About Etripamil
Etripamil, Milestone's lead investigational product, is a novel calcium channel blocker nasal spray. It is designed to be a rapid-response therapy that is self-administered by the patient, without the need for direct medical oversight, for elevated and often highly symptomatic heart rate attacks associated with PSVT and AFib-RVR. If approved, etripamil is intended to provide health care providers with a new tool to enable virtual care and patient self-management, and to impart upon the patient a greater sense of control over their condition. Milestone is conducting a comprehensive development program for etripamil, with Phase 3 trials completed and an NDA soon to be submitted in the third quarter of 2023 in paroxysmal supraventricular tachycardia (PSVT). Milestone also has a Phase 2 proof-of-concept trial that is ongoing in patients with atrial fibrillation with rapid ventricular rate (AFib-RVR).
