Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Symptomatic paroxysmal Atrial Fibrillation (AF) who, in the opinion of the investigator, are candidates for catheter ablation for AF
  • Refractory (that is, ineffective, not tolerated, or not desired) or contraindicated to at least one Class I/III antiarrhythmic drugs (AAD)
  • Willing and capable of providing consent
  • Able and willing to comply with all pre-, post-, and follow-up testing and requirements

Exclusion Criteria:

  • Previously diagnosed with persistent or long-standing persistent AF (more than [>] 7 days in duration)
  • Previous surgical or catheter ablation for AF
  • Significant congenital anomaly or medical problem that in the opinion of the investigator would be a contraindication to catheter ablation for AF
  • Current enrollment in an investigational study evaluating another device or drug
  • Life expectancy less than 12 months
  • Any contraindications as defined in the Protocol

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Occurences of Early Onset Primary Adverse Events (PAEs) Within 7 days of the Index Ablation Procedure
Time Frame: Within 7 days post index procedure
PAE's will include the following adverse events: atrio-esophageal fistula, phrenic nerve paralysis, cardiac tamponade/perforation, pulmonary vein stenosis (PVS), device or procedure related death, stroke/cerebrovascular accident (CVA), major vascular access complication/bleeding, thromboembolism, myocardial infarction, transient ischemic attack (TIA), pericarditis, heart block, pulmonary edema (respiratory insufficiency), and vagal nerve injury/gastroparesis.
Within 7 days post index procedure
Freedom From Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmias Episodes
Time Frame: Day 61-1095 post-index procedure
Freedom from documented (symptomatic and asymptomatic) atrial tachyarrhythmias (atrial fibrillation [AF], atrial tachycardia [AT] or atrial flutter [AFL] of unknown origin) episodes will be reported. AFL of unknown origin is defined as all AFL except those Cavotricuspid isthmus CTI dependent AFL as confirmed by 12-Lead electrocardiogram (ECG) and entrainment maneuvers in an evaluation period study.
Day 61-1095 post-index procedure

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
