New Treatments for Troublesome Bleeding in Implanon Users

Phase 4 Study Comparison of Two Combined Oral Contraceptive Regimens and an Intravaginal Hormonal Ring Against Placebo for Management of Bleeding Problems in Women Using Implanon, the Sub-dermal Contraceptive Implant

Most Implanon users experience a reduction in the frequency and volume of menstrual bleeding, but a substantial minority experience unpredictable and frequent and/or prolonged episodes of bleeding. This is a double blind, placebo controlled, randomised study with an additional randomised non-blinded arm. Two hundred women between the ages of 18-45 years, who are Implanon users with prolonged or frequent breakthrough bleeding (WHO definition) will be recruited and randomised into 4 equal-sized treatment groups of 50 women assigned to Marvelon 7 days or 21 days, NuvaRing 21 days or placebo. Recruited subjects will maintain a daily menstrual diary chart for a minimum of 90 days prior to randomisation, and will be enrolled into the treatment phase provided that they have met one of the World Health Organization criteria for prolonged or frequent bleeding Following the initial 90 day record, eligible women will begin designated treatment on day 1 of the next episode of bleeding or spotting. Analysis of the subsequent menstrual pattern will begin from day 1 of that bleeding/spotting episode and will continue through 90 days.

Detailed Description

This is a double blind, placebo controlled, randomised study with an additional randomised non-blinded arm. Two hundred women between the ages of 18-45 years, who are Implanon users with prolonged or frequent breakthrough bleeding (WHO definition) will be recruited and randomised into 4 equal-sized treatment groups of 50 women assigned to Marvelon 7 days or 21 days, NuvaRing 21 days or placebo. Recruited subjects will maintain a daily menstrual diary chart for a minimum of 90 days prior to randomisation, and will be enrolled into the treatment phase provided that they have met one of the World Health Organization criteria for prolonged or frequent bleeding (in the 90 day reference period one episode of bleeding and/or spotting lasting > 10 days, or more than 4 bleeding/spotting episodes). Randomisation will be performed by computer generation of a random number table in blocks of ten, with equal numbers in each of the four groups. The medications will be packed in sequentially numbered and sealed opaque envelopes (independent of the investigators).

Following the initial 90 day record, eligible women will begin designated treatment on day 1 of the next episode of bleeding or spotting. Analysis of the subsequent menstrual pattern will begin from day 1 of that bleeding/spotting episode and will continue through 90 days. Analysis of the pre-treatment menstrual pattern will include the 90 days immediately preceding the bleeding episode in which treatment starts.

Women will participate in the study for approximately seven months depending on their bleeding pattern.

Data analysis:

Data will be analysed on an intention to treat basis, entered on SPSS and analysed prior to breaking the randomisation code. Frequency analyses will be undertaken for demographic data and means (SD) compared to check effectiveness of the randomisation scheme. Total number of days of spotting, bleeding, bleeding and spotting and number of episodes during the pre and post 90 days reference period will be entered.
