NCT02932007

Brief Summary

The goal of this pilot study is to explore the efficacy of chloroquine in terminating persistent AF and assess its potential role as a pharmacological cardioversion agent for the management of AF.

Study Arms (1)

Chloroquine Phosphate

EXPERIMENTAL

Chloroquine Phosphate will be provided at 500 mg dosage strength for oral administration. Patient will be instructed to take 2 tablets per day on the first two days and 1 tablet each day for the next 12 days for a total of 14 days treatment.

Drug: Chloroquine Phosphate

Interventions

Two tablets of study drug are to be taken on the day of study drug initiation and the next day, followed by one tablet each day for the next 12 days. Study drug to be orally administered and taken with food.

Chloroquine Phosphate

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18 years and older
  • History of symptomatic persistent AF Persistent AF - defined as continuous AF that is sustained more than 7 days but less than 12 months. Episodes of AF of ≥ 48 hours duration in which a decision is made to terminate with electrical or pharmacological cardioversion prior to 7 days will also be classified as persistent AF
  • AF must be documented at least once either by ECG, event monitoring, loop recorder, telemetry, trans-telephonic monitoring, pacemaker or cardiac defibrillator readouts within 24 months prior to enrollment
  • Currently on anticoagulation therapy as indicated per local guidelines, which is considered optimal for stroke prevention in the opinion of the investigator
  • Implanted dual chamber pacemaker/ICD capable of monitoring atrial arrhythmias or willingness to wear a 2 weeks event monitor if patient does not have a device capable of monitoring atrial arrhythmias
  • Signed informed consent

You may not qualify if:

  • Age \< 18 years
  • AF felt to be secondary to an obvious reversible cause such as, but not limited to, acute myocardial infarction, pulmonary embolism, recent surgery, pericarditis, alcohol intoxication, hypoxemia, or thyrotoxicosis
  • Structural heart disease including patients with artificial heart valves or valvular AF
  • Obstructive coronary artery disease or history of any myocardial infarction
  • Ejection fraction \< 50% within 1 year of consent
  • Severe or moderate to severe aortic stenosis, mitral stenosis, aortic regurgitation, or mitral regurgitation per PI discretion
  • Prolonged QTc of \>460 msec on baseline ECG
  • Contraindications to quinolines
  • Known allergy or hypersensitivity to Chloroquine
  • Use of amiodarone 12 months prior to enrollment
  • History of AF ablation within 30 days prior to enrollment
  • Renal impairment (eGFR \< 30 mL/min/1.73 m2 or Serum Creatinine \> 1.25 mg/dL) for subjects over the age of 65
  • Hepatic disease (ALT/AST 2X the upper normal limit)
  • History of alcohol abuse and/or drug abuse per PI discretion
  • Pre-existing auditory damage
  • +7 more criteria
