Comparative Trial in Hormone Withdrawal Associated Symptoms

Phase 3

Completed

• Conditions: Oral Contraceptive
• Interventions: Drug: EE20/DRSP (YAZ, BAY86-5300); Drug: Ethinylestradiol (EE) and desogestrel (DSG) (Mercilon)

• Registration Number: NCT01076582
• Lead Sponsor: Bayer

Brief Summary

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.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: Female
• Target Recruitment: 592

Inclusion Criteria

• Subjects aged between 18 and 35 years (inclusive)
• Smokers with a maximum age of 30 years at time of informed consent
• Healthy female subjects requesting contraception and currently using a low-dose EE containing oral contraceptives (OC) in a 21-day regimen (for at least three months) and suffering from at least two of the hormone withdrawal associated symptoms headache, pelvic pain and bloating during all three months prior the planned baseline cycle and requiring further OC use
• To be valid for randomization, the total 7-day composite score of hormone-withdrawal symptoms during the baseline cycle must show an increase of at least 50% during Day 22 - 28 versus the 21-day composite score during Day 1 - 21 (21-day score divided by three [for normalization])
• History of regular cyclic menstrual periods

rescue medication consumption	baseline cycle and cycle 4
bleeding pattern	reference period is 90 days.
Adverse Event collection	up to 10 days after end of cycle 4
change from baseline to cycle 4 in number of days, where individual hormone withdrawal symptoms are present on cycle days 22 - 28 (i.e. Likert Scale >= 1),	Cycle days 22 - 28 of baseline cycle and cycle 4
change from baseline to cycle 4 in maximum intensity of individual hormone withdrawal symptoms on cycle days 22 - 28,	Cycle days 22 - 28 of baseline cycle and cycle 4
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),	Cycle days 22 - 28 of baseline cycle and cycle 4
evaluation of questionnaires: Q-LES-Q (short version)	baseline cycle and cycle 4
blood pressure	up to 10 days after end of cycle 4
