Microgynon Riociguat Drug Interaction Study in Healthy Postmenopausal Women

August 13, 2015 updated by: Bayer

Microgynon Riociguat Drug Interaction Study to Investigate the Effect of Riociguat 2.5 mg 3 Times Daily Multiple-dose Treatment on the Plasma Concentrations of / Exposure to Levonorgestrel and Ethinyl Estradiol in Healthy Postmenopausal Women in a 2-fold Crossover Design

Physicians might be concerned that Adempas may have a metabolic interaction with oral contraceptives (OC) that could decrease the contraceptive efficacy of the OC. The information regarding lack of potential pharmacokinetic interaction has been communicated; there is a need for more re-assurance and further data that there is no interaction between Adempas and OCs. A drug-drug interaction study of riociguat with an OC such as Microgynon in the least vulnerable population for these purposes, i.e. healthy postmenopausal women, is considered adequate to inform about safe use of Adempas with OCs.

Study Overview

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

52 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Area under the plasma concentration time curve (AUC) of Ethinylestradiol (EE)
Time Frame: Up to 4 months
Plasma concentrations Ethinyl estradiol (EE) and levonorgestrel (LNG)
Up to 4 months
Area under the plasma concentration time curve (AUC) of Levonorgestrel (LNG)
Time Frame: Up to 4 months
Up to 4 months
Maximal concentration (Cmax) of Ethinylestradiol (EE)
Time Frame: Up to 4 months

Time Frame: Up to 4 months

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.
