Milestone Pharmaceuticals (MIST) received approval from China’s National Medical Products Administration (NMPA) for etripamil nasal spray to treat paroxysmal supraventricular tachycardia (PSVT) in adults in China, marking the first regulatory approval of etripamil outside the United States.
The decision triggers a $2.0 million milestone payment to Milestone. Everest Medicines holds exclusive rights to develop and commercialize etripamil in Greater China and, under the license, Milestone is eligible for up to $98.0 million in additional commercial and development milestones plus tiered royalties of up to 18% on future sales. Approval is supported by the global Phase 3 RAPID study and China Phase 3 JX02002 trial, where etripamil was significantly superior to placebo in converting PSVT to sinus rhythm within 30 minutes (hazard ratio 3.002; p=0.0005), with comparable adverse events to placebo and no serious adverse events within 24 hours of dosing across Phase 3 studies.

Milestone Pharmaceuticals (Nasdaq: MIST) reported results from a 247‑patient longitudinal web-based survey on paroxysmal supraventricular tachycardia (PSVT), presented at the ESC Congress 2026. The study evaluated how PSVT affects daily life and quality of life between episodes in adults in the United States and United Kingdom.
According to Milestone, about two-thirds of patients changed their lifestyle to avoid stress and nearly 40% reduced activity or exercise. Seventy‑three percent reported daytime activity interruption, with driving (53%) and travel (43%) commonly avoided and rated as particularly bothersome. Persistent anxiety, burdensome medication side effects, and dissatisfaction with sleep (30%) and work capacity (22%) highlight substantial quality‑of‑life impact and an unmet treatment need.
Milestone Pharmaceuticals (Nasdaq: MIST) has enrolled the first patient in ReVeRA-301, a pivotal Phase 3, multinational, randomized, double-blind, placebo-controlled trial of etripamil nasal spray for atrial fibrillation with rapid ventricular rate (AFib-RVR). The study will include approximately 150 patients.
Prompted by symptoms, patients will self-administer the same 70 mg repeat-dose regimen of etripamil that is FDA approved for paroxysmal supraventricular tachycardia (PSVT) as CARDAMYST. The primary endpoint is ventricular rate reduction within 30 minutes, with a key secondary endpoint of symptom improvement. Milestone is pursuing a single-study sNDA pathway for AFib-RVR based on prior Phase 2 data showing reduced ventricular rate and improved symptom relief and treatment satisfaction.
