Secondary Outcome Measures

  1. Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) in Part 1 [From Baseline up to Safety Follow-Up during Treatment Sequences A and B (up to Day 46)]

    An adverse event (AE) was any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. TEAEs were defined as AEs with a start date/time on or after the first dose of study medication (OC or PSL) or any unresolved event already present before administration of study medication that worsened in intensity following exposure to the treatment.

  2. Percentage of Participants With Serious TEAEs in Part 1 [From Baseline up to Safety Follow-Up during Treatment Sequences A and B (up to Day 46)]

    Serious AEs were defined as any untoward medical occurrence that resulted in death, is life threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent disability, is a congenital anomaly, or is an important medical event which based on medical or scientific judgement may jeopardize the participants, or may require medical or surgical intervention to prevent any of the above.

  3. Percentage of Participants With TEAEs in Part 2 [From Baseline up to Safety Follow-Up during Treatment Sequences A and B (up to Day 42)]

    An AE was any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. TEAEs were defined as AEs with a start date/time on or after the first dose of study medication (OC or PSL) or any unresolved event already present before administration of study medication that worsened in intensity following exposure to the treatment.

  4. Percentage of Participants With Serious TEAEs in Part 2 [From Baseline up to Safety Follow-Up during Treatment Sequences A and B (up to Day 42)]

    Serious AEs were defined as any untoward medical occurrence that resulted in death, is life threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent disability, is a congenital anomaly, or is an important medical event which based on medical or scientific judgement may jeopardize the participants, or may require medical or surgical intervention to prevent any of the above.

  5. Steady State Plasma Concentration (Cmax,ss) of Padsevonil in Part 1 [Day 12 and 13 (Sequence A) and Day 29 and 30 (Sequence B)]

    Maximum observed plasma concentration of padsevonil at steady-state was reported. This outcome measure was planned to be analyzed for 'PSL + Oral contraceptive' and 'PSL Alone' arms.

  6. Steady State Plasma Concentration (Cmax,ss) of Padsevonil in Part 2 [Day 8 and 9 (Sequence A) and Day 25 and 26 (Sequence B)]

    Cmax,ss is the steady state plasma concentration of padsevonil.

  7. Area Under the Concentration-time Curve From Time 0 to Time Tau (AUC[0-tau]) of Padsevonil in Part 1 [Day 12 and 13 (Sequence A) and Day 29 and 30 (Sequence B)]

    Area under the concentration-time curve over a dosing interval from time 0 to tau for padsevonil was reported. This outcome measure was planned to be analyzed for 'PSL + Oral contraceptive' and 'PSL Alone' arms.

  8. Area Under the Concentration-time Curve From Time 0 to Time Tau (AUC[0-tau]) of Padsevonil in Part 2 [Day 8 and 9 (Sequence A) and Day 25 and 26 (Sequence B)]

    AUC0-tau is area under the concentration-time curve over a dosing interval from time 0 to tau of padsevonil.

Title Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) in Part 1
Description An adverse event (AE) was any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. TEAEs were defined as AEs with a start date/time on or after the first dose of study medication (OC or PSL) or any unresolved event already present before administration of study medication that worsened in intensity following exposure to the treatment.
Time Frame From Baseline up to Safety Follow-Up during Treatment Sequences A and B (up to Day 46)
