Comparative Trial in Hormone Withdrawal Associated Symptoms

October 27, 2014 updated by: Bayer

A Multi-centre, Randomized, Double-blind, Active Control, Parallel-group, 2-arm Study to Investigate the Effect of Ethinylestradiol / Drospirenone (0.02 mg/3 mg) Oral Contraception in a 24/4 Regimen Compared to Ethinylestradiol / Desogestrel (0.02 mg/0.15 mg) Oral Contraception in a 21/7 Regimen on Hormone Withdrawal Associated Symptoms in Otherwise Healthy Women After 4 Cycles of Treatment

This clinical research study will examine whether an oral contraceptive pill taken with a monthly hormone-free interval of 4 days reduces hormone withdrawal associated symptoms compared to an oral contraceptive pill taken with a monthly hormone-free interval of 7 days after 4 cycles of treatment.

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 35 years (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
Time Frame

Time Frame: Cycle days 22 - 28 of baseline cycle and cycle 4.
Cycle days 22 - 28 of baseline cycle and cycle 4.

Secondary Outcome Measures

Secondary Outcome Measures

change from baseline to cycle 4 in the sum of individual scores during cycle days 22 - 28 (AUC of days 22 - 28 for each score),

Time Frame: Cycle days 22 - 28 of baseline cycle and cycle 4

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.
