Outcome

Type Measure Description Time frame Safety issue
Primary Number of Participants With Paroxysmal AF With an Event of Documented Symptomatic Atrial Fibrillation (AF)/Flutter A documented episode of symptomatic AF /Flutter was defined as AF/Flutter documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. Atrial flutter, a closely related rhythm disorder, was distinguished from AF by the presence of distinctive flutter p-waves at regluar intervals. The occurrence of symptomatic atrial flutter was treated as an occurrence of symptomatic AF for this outcome measure. "Censored" in the table below refers to participants who did not have a documented episode of symptomatic AF or flutter. From first dose of study drug (Day 1) to the first symptomatic recurrence of AF/flutter (up to Week 24) No
Secondary Number of Participants With Persistent AF and in Both AF Subgroups Combined With an Event of Documented Symptomatic AF/Flutter A documented episode of symptomatic AF/flutter was defined as AF/flutter documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. Atrial flutter, a closely related rhythm disorder, was distinguished from AF by the presence of distinctive flutter p-waves at regluar intervals. The occurrence of symptomatic atrial flutter was treated as an occurrence of symptomatic AF for this outcome measure. "Censored" in the table below refers to participants who did not have a documented episode of symptomatic AF or flutter. From first dose of study drug (Day 1) to the first symptomatic recurrence of AF/flutter (up to Week 24) No
Secondary Number of Participants With Paroxysmal AF or Persistent AF With an Event of Documented Symptomatic AF (Exclusive of Atrial Flutter) A documented episode of symptomatic AF was defined as AF documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. "Censored" in the table below refers to participants who did not have a documented episode of symptomatic AF. From first dose of study drug (Day 1) to the first symptomatic recurrence of AF (up to Week 24) No
Secondary Number of Participants in Both AF Subgroups Combined With an Event of Documented Symptomatic AF (Exclusive of Atrial Flutter) A documented episode of symptomatic AF was defined as AF documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. "Censored" in the table below refers to participants who did not have a documented episode of symptomatic AF. From first dose of study drug (Day 1) to the first symptomatic recurrence of AF (up to Week 24) No
Secondary Number Participants With Paroxysmal or Persistent AF With an Event of Documented Symptomatic or Asymptomatic AF/Flutter A documented episode of symptomatic or asymptomatic AF/flutter was defined as AF/flutter documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. Asymptomatic episodes of AF or flutter were recorded by TTM during routine bi-weekly transmissions. Atrial flutter, a closely related rhythm disorder, was distinguished from AF by the presence of distinctive flutter p-waves at regluar intervals. "Censored" in the table below refers to participants who did not have a documented episode of symptomatic or asymptomatic AF/flutter. From first dose of study drug (Day 1) to the first symptomatic or asymptomatic recurrence of AF/flutter (up to Week 24) No

Secondary Number of Participants With Paroxysmal or Persistent AF With an Event After Completion of Day 7 to the Occurrence of Symptomatic AF/Flutter A documented episode of symptomatic AF/flutter was defined as AF/flutter documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. Atrial flutter, a closely related rhythm disorder, was distinguished from AF by the presence of distinctive flutter p-waves at regluar intervals. "Censored" in the table below refers to participants who did not have a documented episode of symptomatic AF/flutter. From completion of Day 7 of study drug to the first symptomatic recurrence of AF/flutter (up to Week 24) No
Secondary Number of Participants in the Combined AF Subgroups With an Event After Completion of Day 7 to the Occurrence of Symptomatic AF/Flutter A documented episode of symptomatic AF/flutter was defined as AF/flutter documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. Atrial flutter, a closely related rhythm disorder, was distinguished from AF by the presence of distinctive flutter p-waves at regluar intervals.

Secondary Number of Participants With Paroxysmal or Persistent AF With an Event That Occurred After Completion of Day 7 to the Occurrence of Symptomatic AF (Exclusive of Flutter) A documented episode of symptomatic AF was defined as AF documented by an electrocardiogram (ECG) or transtelephonic monitoring (TTM) tracing associated with symptoms consistent with AF. "Censored" in the table below refers to participants who did not have a documented episode of symptomatic AF. From completion of Day 7 of study drug to the first symptomatic recurrence of AF (up to Week 24) No

"Censored" in the table below refers to participants who did not have a documented episode of symptomatic AF. From completion of Day 7 of study drug to the first symptomatic recurrence of AF (up to Week 24) No
Secondary Annualized Number of AF/Flutter Rescue Episodes During the Treatment Period Rescue was defined as any pharmacological/electrical/surgical intervention for the termination/prevention of AF/flutter with a maximum of one rescue episode counted per day. Note: all annualized values were calculated by counting the number of rescue episodes, dividing by the number of days on treatment, then multiplying that number by 365.25. From first dose of study drug (Day 1) to the last dose of study drug (up to Week 24) No
Secondary Annualized Cumulative Frequency of Symptomatic AF/Flutter Recurrences During the Treatment Period Values were annualized by counting the number of episodes of symptomatic AF/flutter recurrences (maximum of one per day), dividing by the number of days on treatment, then multiplying this number by 365.25. From first dose of study drug (Day 1) to the last dose of study drug (up to Week 24) No
Secondary Annualized Cumulative Frequency of Symptomatic AF Recurrences During the Treatment Period Values were annualized by counting the number of episodes of symptomatic AF recurrences (maximum of one per day), dividing by the number of days on treatment, then multiplying this number by 365.25.
