About this study

Official title: An Open-label Study to Evaluate Contraceptive Efficacy and Safety of the Transdermal Contraceptive System of 17dNorgestimate and Ethinyl Estradiol With the Oral Contraceptive Mercilon.

The purpose of the study was to compare the contraceptive efficacy and safety of the transdermal patch to Mercilon.

Read the detailed description

This is an open-label, multicenter, international study to evaluate the contraceptive efficacy, safety, cycle control, compliance, and subject satisfaction of the transdermal patch compared with Mercilon. Fourteen hundred healthy women will receive study medication for either 6 or 13 cycles. The first 265 transdermal patch subjects and the first 200 Mercilon subjects will be expected to complete 13 cycles of medication. All subsequent subjects will be expected to complete 6 cycles. The ratio of subjects assigned to the transdermal patch arm of the study and to the Mercilon arm will be 4:3. At admission (Visit 1) study drug, diary cards and subject instructions for Cycle 1 and replacement patches for Cycles 1 to 6 are dispensed. The first patch will be applied and Mercilon pill will be taken on the first day of menses. Study medication and diary cards will be issued on day 28 of Cycles 1 (Visit 2) and 3 (Visit 3), and those continuing for 13 cycles will receive study drug again on day 28 of Cycles 6 (Visit 4) and 9 (Visit 5). Diary cards and empty medication packages will be collected at every visit. Final visits are on day 28 of Cycles 6 and 9. Diary card information was used to record compliance and bleeding information (to assess cycle control). Contraceptive efficacy was assessed by means of the Pearl Index and life table analysis (gross cumulative probability of pregnancy). Safety evaluations were based on adverse events, which were collected throughout the study, and changes in gynecologic examinations, vital signs, and laboratory results from prestudy to final visit. A transdermal patch, containing 6 mg NGM and 0.75 mg EE, delivering 250 ug NGM and 25 ug EE over 24 hours for 7 days, is worn for 1 week and replaced for 3 consecutive weeks.The fourth week is patch-free. A Mercilon pill is taken for 21 consecutive days followed by a 7-day pill-free week.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • norelgestromin + ethinyl estradiol; mercilonDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Contraceptive efficacy of the 2 treatments was estimated by determination of pregnancy rates, using the Pearl Index and life table analysis (cumulative probability of pregnancy). Safety was evaluated throughout the study.

Secondary outcomes (1)

  1. Cycle control and compliance were assessed with diary cards containing bleeding and dosing information.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing norelgestromin + ethinyl estradiol; mercilon in people with Contraception, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Contraceptive efficacy of the 2 treatments was estimated by determination of pregnancy rates, using the Pearl Index and life table analysis (cumulative probability of pregnancy). Safety was evaluated throughout the study.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00236782, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2011.
