December 5, 2014 updated by: Bial - Portela C S.A.

Effect of Repeated Administration of Eslicarbazepine Acetate (BIA 2-093) 800mg Once-daily on the Pharmacokinetics of a Combined Oral Contraceptive in Healthy Female Subjects

The purpose of this study is to investigate whether multiple-dose administration of eslicarbazepine acetate (ESL, BIA 2-093) 800 mg once-daily (QD) affects the pharmacokinetics and tolerability of the components of a combined oral contraceptive (ethinyloestradiol and levonorgestrel).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

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

18 years to 40 years (Adult)

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
Cmax - Maximum Observed Plasma Concentration
Time Frame: 15-day
To investigate whether multiple-dose administration of eslicarbazepine acetate (ESL, BIA 2-093) 800 mg once-daily (QD) affects the pharmacokinetics of the components of a combined oral contraceptive (ethinyloestradiol and levonorgestrel).
15-day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
AUC0-t - Area Under the Plasma Concentration Versus Time Curve From Time Zero to the Last Sampling Time at Which Concentrations Were at or Above the Limit of Quantification
Time Frame: 15-day
To investigate whether multiple-dose administration of eslicarbazepine acetate (ESL, BIA 2-093) 800 mg once-daily (QD) affects the pharmacokinetics of the components of a combined oral contraceptive (ethinyloestradiol and levonorgestrel).
15-day
AUC0-∞ - Area Under the Plasma Concentration Versus Time Curve From Time Zero to Infinity
Time Frame: 15-day
To investigate whether multiple-dose administration of eslicarbazepine acetate (ESL, BIA 2-093) 800 mg once-daily (QD) affects the pharmacokinetics of the components of a combined oral contraceptive (ethinyloestradiol and levonorgestrel).

Primary Completion (Actual)

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.
