Safety Study of Intranasal Etripamil for the Termination of Spontaneous Episodes of Paroxysmal Supraventricular Tachycardia (PSVT). NODE-302

Multi-Centre, Open-Label, Safety Study of Etripamil Nasal Spray in Spontaneous Episodes of Paroxysmal Supraventricular Tachycardia The NODE-302 Trial (Extension of NODE-301)

The primary objective of this study is to evaluate the safety of etripamil nasal spray (NS) 70 mg when self-administered by patients with an episode of Paroxysmal Supraventricular Tachycardia in an outpatient setting (i.e., without medical supervision).

Study Overview

• Status: Terminated
• Conditions: Paroxysmal Supraventricular Tachycardia
• Intervention / Treatment: Drug: Etripamil NS 70 mg; Device: Aptar Pharma Nasal Spray Bidose System

Detailed Description

The NODE-302 study is an extension of the NODE-301 efficacy study. It is a multi-centre, open label study designed to evaluate the safety of etripamil NS 70 mg when self-administered by patients for spontaneous episodes of PSVT in an outpatient setting. All patients randomized in the NODE-301 study and who meet the inclusion and exclusion criteria of the NODE-302 study are eligible for the NODE-302 study.

After each episode of PSVT, patients will have the option to continue in the NODE-302 study and manage subsequent episodes of PSVT with etripamil NS 70 mg if they do not meet any withdrawal criteria.

Each episode of PSVT will be documented by an ambulatory cardiac monitoring system (CMS) that will be placed on the chest by the patient or caregiver when symptoms begin, and will record at least 5 hours of continuous ECG.

The study will include a Qualification Visit, a Treatment Period(s) , a Follow-up Visit(s) ,a Final Study Visit and if necessary an Early Termination Visit if the patient withdraws from the study after taking etripamil NS 70 mg and had a Follow-up Visit, or the patient withdraws from the study and did not take etripamil NS 70 mg.

Atrial fibrillation (event lasting longer than 30 seconds);

2. Any drug-related or procedure-related serious adverse event during the NODE-301 study;
3. Any severe adverse event (AE) in the NODE-301 study that was severe enough to preclude administration of etripamil NS 70 mg in the NODE-302 study;
4. Any new drug prescribed after the end of the patient's participation in the NODE-301 study that could lower blood pressure or decrease AV node conduction;
5. Systolic blood pressure <90 mmHg after a 5-minute rest in sitting position at the NODE-302 Qualification Visit;
6. Any symptoms consistent with clinically severe hypotension such as presyncope, medically significant lightheadedness, syncope, nausea, or vomiting;
7. New therapy with digoxin, amiodarone, or any Class I or III antiarrhythmic drug added after the end of the patient's participation in the NODE-301 study;

9. New symptoms of congestive heart failure defined by the New York Heart Association Class II to IV since randomization in the NODE-301 study;
10. New stroke since randomization in the NODE-301 study;
11. New evidence of a significant physical or psychiatric condition including drug abuse, which in the opinion of the Investigator, could jeopardize the safety of the patient, or impede the patient's capacity to follow the study procedures since randomization in the NODE-301 study;
12. New syncope since randomization in the NODE-301 study, especially if observed during the monitoring of the event treated in the NODE-301 study;
13. New evidence of hepatic dysfunction defined as alanine aminotransferase or aspartate aminotransferase >3 × the upper limit of normal (ULN) or total bilirubin >2 × ULN, unless due to Gilbert syndrome observed at the NODE-302 Qualification Visit;

14. New evidence of renal dysfunction as determined by an estimated glomerular filtration rate assessed at the NODE-302 Qualification Visit as follows:

    1. <60 mL/min/1.73 m2 for patients <60 years of age,
    2. <40 mL/min/1.73 m2 for patients ≥60 and <70 years of age, or
