E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety and efficacy of a single oral dose of vanoxerine HCl compared to placebo in subjects with AF/AFL for conversion to sinus rhythm. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Subject has been informed of the investigational nature of this study and has given written, informed consent in accordance with institutional, local, and national guidelines. 2. Able to return for Day 8 follow up and provides at least two modes of contact information (e.g., home and mobile phone numbers, address) and contact information for at least one close contact (e.g., family member or friend) to facilitate Day 30 vital status follow up. 3. Male or female 18 years of age or greater. 4. Onset of AF/AFL within the 7 calendar days preceding randomization, based on symptoms. 5. AF/AFL documented by ECG during the screening period. Subjects with (a) both AF and AFL or (b) coarse fibrillation that is difficult to discern from AFL will be designated as AF. AF or AFL must be reconfirmed electrocardiographically e.g., bedside monitor, telemetry, paper ECG, etc., immediately (within 5 minutes) prior to study drug administration. Subjects who spontaneously convert to sinus rhythm after randomization but before study drug administration will not receive study drug and will not proceed further in the study. 6. Adherence to local clinical standards or the ACC/AHA or ESC practice guidelines for AF/AFL regarding thromboembolic event prevention and treatment.

E.4 | Principal exclusion criteria |
1. Previous exposure to vanoxerine HCl. 2. Women of childbearing potential (neither surgically sterilized nor post-menopausal defined as cessation of menses for over one year). 3. Systolic blood pressure <110 mmHg during screening (unless documented to be usual value). 4. Average heart rate <60 bpm documented by screening ECG. 5. Average QTc >440 msec documented by screening ECG. 6. QRS interval >140 msec documented by screening ECG. 7. Paced atrial rhythm on screening ECG. 8. Serum potassium <4.0 mEq/L or mmol/L by local laboratory at screening. 9. Serum magnesium < 1.6 mEq/L or mmol/L or 1.8 mg/dL by local laboratory at screening. 10. History of receiving another Class I or Class III antiarrhythmic drug within 3 days prior to randomization. Excluded Class I antiarrhythmic drugs include quinidine, procainamide, disopyramide, lignocaine, mexilitine, flecainide, and propafenone. Excluded Class III drugs include, dofetilide, sotalol, dronedarone, and ranolazine. 11. History of amiodarone (oral or IV) within the 90 days prior to randomization. 12. Native or prosthetic aortic or mitral stenosis with aortic valve area ≤ 1.0 cm2 or mitral valve area of <1.5 cm2 or any other valvular disease for which surgery is indicated. 13. Treatment with any loop diuretic (e.g., furosemide, bumetanide, torsemide, ethacrynic acid, etc.) in the 30 days prior to randomization. 14. Ejection fraction of <35% within the 3 months prior to randomization (most recent measure if more than one). 15. AF/AFL as a result of surgery (postoperative AF/AFL) within 30 days prior to randomization. 16. History of electrical cardioversion within the 7 calendar days prior to randomization. 17. History of any polymorphic ventricular tachycardia including torsades de pointes. 18. History or family history of long QT syndrome or other inherited arrhythmia syndrome. 19. History of ventricular tachycardia requiring drug or device therapy. 20. Participation in another investigational drug or device trial within 30 days prior to randomization. (Subjects in registries may participate with approval of registry sponsor.) 21. Acute cardiovascular events (myocardial infarction, pulmonary embolism, cerebrovascular accident, unstable angina, or transient ischemic attack) within the 90 days prior to randomization. 22. Psychiatric disorder, active alcohol/drug abuse, or other circumstance or condition that, in the investigator’s opinion, may interfere with any aspect of protocol adherence (including Day 8 visit or Day 30 follow-up) or a subject’s ability to give informed consent. 23. Untreated hyperthyroidism 24. Acute pericarditis 25. Any unrelated illness (e.g., substantial infection, fever > 37.8 ď‚°Celsius or prescribed antibiotics in the last 7 days, inflammation, acute rheumatic fever, metastatic cancer, severe hepatic impairment, or other medical conditions or laboratory abnormalities), which, in the judgment of the investigator would significantly jeopardize subject’s clinical status. 26. Receipt of potent CYP3A4 inhibitors within 5 half-lives prior to randomization. Potent CYP3A4 inhibitors include but are not limited to boceprevir, clarithromycin, conivaptan, grapefruit juice, indinavir, itraconazole, ketoconazole, lopinavir/ritonavir, mibefradil, nefazadone, nelfinavir, posaconazole, ritonavir, saquinavir, telaprevir, telithromycin, and voriconazole.

E.5 End points |
E.5.1 | Primary end point(s) |
• Conversion to sinus rhythm (or atrial paced rhythm in the case of subjects with a pacemaker and atrial leads) documented by ECG (Holter ECG, 12-lead ECG, monitor lead ECG, or other format ECG) of at least 1 continuous minute within the 24 hours defined by the time of study drug administration through 24 hours after the time of study drug administration. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Length of Stay (from time of study drug administration) • Sinus rhythm present at 12 and 24 hours from study drug administration and at the Day 8 visit. • Time to restoration of sinus rhythm through 24 hours. • Change in subject symptom score from baseline to 4 and 24 hours from study drug administration and to Day 8. Safety endpoint will comprise the occurrence of any of the following events: a. Death through Day 8. b. Ventricular fibrillation on ECG through 32 hours. c. Ventricular tachycardia with heart rate >120 bpm requiring intervention through 32 hours. d. Torsades de pointes >10 seconds on ECG through 32 hours. (All episodes of torsades de pointes will be reported [including duration] as a safety variable. Only torsades de pointes >10 seconds will be included as a primary safety outcome endpoint.)
