Milestone® Pharmaceuticals Inc. announced that the United States Food and Drug Administration accepted the Company’s New Drug Application on May 26, 2024 for CARDAMYST nasal spray, its lead investigational product for the management of paroxysmal supraventricular tachycardia.
MONTREAL and CHARLOTTE, N.C., May 29, 2024 (GLOBE NEWSWIRE) -- Milestone® Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced that the United States Food and Drug Administration (FDA) accepted the Company’s New Drug Application (NDA) on May 26, 2024 for CARDAMYST (etripamil) nasal spray, its lead investigational product for the management of paroxysmal supraventricular tachycardia (PSVT). The FDA Prescription Drug User Fee Act (PDUFA) target date is 10 months from the acceptance date of May 26, 2024.
“The FDA’s acceptance of our NDA for CARDAMYST brings Milestone one step closer in our mission in providing a new, convenient and effective treatment option for patients with PSVT,” said Joseph Oliveto, President, and Chief Executive Officer of Milestone Pharmaceuticals. “We understand the frequent impact that PSVT has on patients, as well as the underappreciated burden it places on their families and caregivers. Our progress toward providing a sense of security for patients is a result of the dedicated Milestone team, patients, and investigators to whom we are thankful.”
The CARDAMYST clinical trial program represents the largest data package ever studied for an acute drug treatment intended for patient self-management of PSVT events. Milestone continues to advance commercial preparations to support the anticipated launch of etripamil with the proposed trade name, CARDAMYST. The brand name is conditionally approved by the FDA.
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 CARDAMYST (etripamil) nasal spray
CARDAMYST 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 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. The clinical trial program for CARDAMYST 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.
