Brief Summary:
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).

Condition or disease Intervention/treatment Phase
Paroxysmal Supraventricular Tachycardia Drug: Etripamil NS 70 mg Phase 3

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.

Primary Outcome Measures :
  1. Time to conversion of an episode of PSVT to sinus rhythm (SR) after study drug administration. [ Time Frame: 18 months ]
    The efficacy analyses will be performed on the Efficacy Population. The primary efficacy variable is the time to conversion of an episode of PSVT to SR after study drug administration.

Criteria

Inclusion Criteria

Patients who meet all of the following criteria will be eligible to participate in the study:

  1. Male or female patients at least 18 years of age;
  2. Signed the NODE-302 written informed consent;
  3. Previously randomized in the NODE-301 study:

    • Received the study drug to treat symptoms the patient believed were consistent with an episode of PSVT during the NODE-301 study, irrespective of the study drug efficacy; OR
    • Did not experience an episode of PSVT or did not use the study drug at the time of the NODE-301 study completion;
  4. Willing and able to comply with all aspects of the study;
  5. Females of childbearing potential who are sexually active must agree to use an approved highly effective form of contraception from the time of signed informed consent until 30 days after the last administration of study drug. Females of childbearing potential should have a negative urine pregnancy test result at the Qualification Visit and at the Follow-up Visit(s), and must use an approved form of contraception between the 2 visits. Approved forms of contraception include hormonal intrauterine devices and hormonal contraceptives (oral birth control pills, Depo Provera®, patch, or other injectables) together with supplementary double barrier methods, such as condoms or diaphragms with spermicidal gel or foam;

    The following categories define females who are NOT considered to be of childbearing potential:

    • Premenopausal females with 1 of the following:

      1. Documented hysterectomy,
      2. Documented bilateral salpingectomy, or
      3. Documented bilateral oophorectomy, or
    • Postmenopausal females, defined as having amenorrhea for at least 12 months without an alternative medical cause; and
  6. Male patients, except those who are surgically sterile, must use an approved highly effective form of contraception during the 3 days after study drug administration.

Exclusion Criteria

Patients who meet any of the following criteria will be excluded from participation in the study, including but not limited to:

  1. Evidence of new severe arrhythmia discovered since the NODE-301 Test Dose Randomization Visit, including those reported on the Cardiac Monitoring System (CMS) report of the outpatient PSVT event treated with the study drug in the NODE 301 study:

    d. Third-degree AV block, Mobitz II second-degree AV block, or Wenckebach with bradycardia ≤40 bpm; e. Significant symptomatic sinus bradycardia heart rate (HR) ≤40 bpm or sinus pauses (≥3 seconds); f. Any significant ventricular arrhythmia (premature ventricular beats and couplets [>6 premature ventricular contractions per 45 seconds electrocardiogram (ECG)] are considered significant); or g. 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;

  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

  • Patient failure to comply with protocol requirements or study-related procedures;
