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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

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.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

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
Pregnancy Rate
Time Frame: Up to 60 days after enrollment

A high sensitivity pregnancy test was performed at inclusion (between 48h and 120h after unprotected intercourse) and then until menses occured or up to 60 days if they did not, at the following time points:

  • 5-7 days after expected date of menses
  • 1 week later
  • every two week after
Up to 60 days after enrollment

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
Prevented Fraction (Number of Prevented Pregnancies Divided by the Number of Expected Pregnancies)
Time Frame: within the menstrual cycle of the unprotected Intercourse
Number of prevented pregnancies divided by the number of expected pregnancies
within the menstrual cycle of the unprotected Intercourse
Impact on Menstrual Bleeding Patterns
Time Frame: within the menstrual cycle of the unprotected Intercourse
Menstrual cycle length post treatment
within the menstrual cycle of the unprotected Intercourse
Frequencies of Subjects With Treatment Emergent Adverse Events
Time Frame: 12-14 days after expected menses
Most common related adverse events in ITT population.
12-14 days after expected menses
