简要总结
NODE-202 is a Phase 2, multicenter, multinational, single dose, open-label, 2-part, sequential design study in pediatric patients with an established diagnosis of paroxysmal supraventricular tachycardia (PSVT) presenting with a symptomatic episode of PSVT.
In Part 1, at least 30 patients aged 12 to <18 years will be enrolled and treated with etripamil nasal spray (NS). Efficacy, safety, tolerability and PK (for at least 12 patients) will be assessed after administration of 70 mg etripamil NS (Part 1A). At least 18 subsequent patients will be enrolled and treated with the etripamil NS with the dose determined by the Pharmacokinetic (PK) analysis and will undergo efficacy and safety/tolerability assessments (Part 1B).
In Part 2, at least 30 patients aged 6 to <12 years will be enrolled and treated with etripamil NS at a dose selected based on appropriate body size-based modeling, as well as efficacy, safety/tolerability, and PK data collected in Part 1. Efficacy, safety, tolerability and PK (for at least 12 patients) will be assessed after administration of etripamil NS (Part 2A). At least 18 subsequent patients will be enrolled and treated with the etripamil NS with the dose determined by the PK analysis and will undergo efficacy and safety/tolerability assessments (Part 2B).
The study will include the following visits: A Screening Visit, A Treatment Visit, , and A Follow-Up/End of Study Visit.
详细描述
NODE-202 is a Phase 2, multicenter, multinational, single-dose, open-label, 2-part, sequential design study of pediatric patients with an established diagnosis of PSVT presenting with a sustained, symptomatic episode of PSVT.
At least 60 evaluable patients administered etripamil NS are estimated as an adequate population to inform on the efficacy and safety of etripamil NS in pediatric patients (aged 6 to <18 years) with PSVT. Patients will be enrolled according to the following sequential design:
Part 1: At least 30 patients aged 12 to <18 years will be treated with 70 mg etripamil NS for a PSVT episode. Efficacy, safety, tolerability and PK (at least for 12 patients) will be assessed after administration of etripamil.
Part 1A: at least 12 patients will undergo efficacy, safety/tolerability, and PK assessments. The data safety monitoring committee (DSMC) will complete an interim assessment of safety, tolerability; if the Sponsor decides to increase the dose above 70 mg for the remaining 18 patients, the Pediatric Committee (PDCO) and the Food and Drug Administration (FDA) will complete an interim assessment of efficacy, safety, tolerability, and PK data before additional patients in this age group can be treated with etripamil at the same or a modified dose level.
Part 1B: at least 18 subsequent patients will be treated with etripamil NS with the dose determined based on Part 1A data analysis and will undergo efficacy and safety/tolerability assessments.

入选标准
- •Patients will be eligible for study participation if they meet all of the following criteria at screening:
- •Male or female patients
- •Part 1: patients 12 to <18 years of age
- •Part 2: patients 6 to <12 years of age
- •Body mass index (BMI) between the 5th and the 85th percentiles interpreted relative sex and age
- •History of PSVT documented by ECG or other monitoring modality (e.g., Holter monitor, event recorder) showing SVT involving the Atrioventricular (AV) node (i.e., Atrioventricular nodal reentry tachycardia (AVNRT) or Atrioventricular reentrant tachycardia (AVRT)). If patient had a prior ablation for PSVT, patient must have documented evidence of PSVT post-ablation
- •Signed written informed consent/assent obtained
- •Per Investigator's decision, females of childbearing potential (defined as any woman or adolescent who has begun menstruation) must additionally satisfy the following criteria:
- •Negative pregnancy test at screening
- •Adequate contraception, unless total abstinence is used
- •Willing and able to comply with study procedures.
排除标准
- •Patients will be excluded from the study if they meet any of the following criteria:
- •History or presence of any of the following at the screening visit:
- •Patients with a history of atrial arrhythmia that does not involve the AV node as part of the tachycardia circuit (e.g., atrial fibrillation, atrial flutter, atrial tachycardia) are not eligible
- •Permanent junctional reciprocating tachycardia
- •Ventricular pre-excitation (e.g., delta wave on ECG, Wolff Parkinson White syndrome)
- •Second- or third-degree AV block
- •Sick sinus syndrome or clinically significant bradycardia (<50 bpm or equivalent in this patient population) on the resting ECG
- •Ventricular tachycardia
- •Long QT syndrome
- •Major structural heart disease (e.g., Ebstein's anomaly, corrected congenital heart disease) or symptoms of congestive heart failure (New York Heart Association class II to IV).
- •Evidence of impaired liver function (alanine aminotransferase [ALT] and/or aspartate aminotransferase [AST] >3 x upper limit of normal for age and gender) at the Screening Visit
- •Evidence of End-Stage Renal Disease as determined by an estimated glomerular filtration rate assessed at the Screening Visit of <15 mL/min/1.73m2, or requiring hemodialysis;
- •Treatment with any of the following that cannot or will not be discontinued during study participation:
- •Any investigational drug within 60 days prior to study drug administration
- •IV beta-adrenergic blocking drugs (e.g., propranolol, esmolol), calcium channel blocking drugs (e.g., verapamil, diltiazem) or amiodarone within 24 hours prior to study drug administration
- •Oral amiodarone within 30 days prior to study drug administration
- •Class I or III antiarrhythmic agents (e.g., flecainide, propafenone, sotalol) within five half-lives prior to study drug administration

- •Known hypersensitivity to verapamil or to any of the excipients of the study drug
- •Any other significant co-morbid condition that may have a negative impact on the patient's participation in the study or likely to result in non-compliance
