Outcomes
Primary Outcomes
Percentage of Participants Who Converted From Atrial Fibrillation (AF) Within 90 Minutes From Start of Infusion and Subsequently Had no AF Recurrence Within 1 Minute of Conversion From AF
Time Frame: Within 90 minutes from the start of infusion (Day 1)
The 12-lead Holter monitoring equipment was used to monitor heart rate and its rhythm. Electrocardiogram (ECG) was performed in a standardized manner after the participant had rested in the semi-supine position for at least 5 minutes. Conversion from AF to normal sinus rhythm within 90 minutes from start of infusion was determined by the investigator and documented with a rhythm strip confirming conversion. Percentages were based on "number of participants converted from atrial fibrillation and absence of recurrence of AF within 1 minute of conversion" divided by "total number of participants" \*100 in each treatment group. Analysis was performed based on Bayesian model.
Secondary Outcomes
- Time to Conversion From Atrial Fibrillation From Start of Infusion(From start of infusion (Day 1) up to Day 2)
- Percentage of Participants With Relapse of AF Within 5 Minutes (IRAF) After Pharmacological or Direct Current (DC) Cardioversion(Within 5 minutes after cardioversion (Day 1))
- Maximum Observed Peak Plasma Concentration (Cmax) of AP30663(Baseline (pre-infusion) and at 5, 15, 25, 30, 45 minutes, 1 hour, 1.5 hours, 4 hours, 8 hours and 24 hours post-infusion)
- Changes From Baseline in Fridericia's Correction of QT Interval (ΔQTcF) Interval Data Over Time(Baseline, 15 minutes, 45 minutes, 2 hours, 8 hours and 24 hours post-dose)
- Area Under the Concentration Time Curve From Pre-dose Concentration up to 30 Minutes (AUC0-0.5) of AP30663(Baseline (pre-infusion) and at 5, 15, 25, 30 minutes post-infusion)
- Area Under the Concentration-Time Curve From Pre-dose (Zero) Through Concentration to Infinity (AUC0-inf) of AP30663(Baseline (pre-infusion) and at 5, 15, 25, 30, 45 minutes, 1 hour, 1.5 hours, 4 hours, 8 hours and 24 hours post-infusion)
- Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious TEAEs(From start of infusion (Day 1) up to follow-up (Day 35))
