About this study

Official title: Determining the Impact of Combined Hormonal Contraceptives on Ulipristal Acetate

The purpose of this research study is to determine if taking a birth control pill effects how well an emergency contraceptive pill called Ulipristal acetate (UPA) works. This type of emergency contraceptive is the most effective oral method available. However, this medication is an anti-progestin and most regular forms of birth control contain progestin (a female hormone). It is unknown if taking the two close together may make the emergency contraceptive not work well. The overall goal of this research is to improve the effectiveness of contraception for women and to better counsel women.

Read the detailed description

Emergency contraception (EC) provides women with an additional line of defense against unintended pregnancy during an act of unprotected intercourse. An antiprogestin, ulipristal acetate (UPA; ellaTM), has emerged as one of the most effective oral options. However, there is currently a lack of information regarding the practical use of UPA. Basic science studies have shown that UPA binds to and prevents progesterone receptor from working, leading to the possible concern that hormonal contraceptives, like the birth control pill, would prevent UPA from working. Ideally, women should start their regular method of birth control soon after EC use but by doing this, they may prevent the UPA EC from working. A woman could just delay starting her regular method of birth control but then she is still at risk for pregnancy.

This proposal has been designed to address this gap in knowledge and will focus on the impact of the birth control pill on UPA's ability to delay ovulation (or the release of an egg). Subjects will undergo a referent cycle UPA only (Cycle 1, 1 month), followed by a washout cycle (Cycle 2, 1 month) and finally UPA with combined oral contraceptives (COCs) dosed 2 days later (Cycle 3, 1 month treatment cycle). The hypothesis is that starting the birth control pill shortly after UPA adversely impacts UPA's ability to delay ovulation.

Study groups in NCT02577601
Study groupRoleWhat they receive
UPA OnlyActive comparatorDuring the first treatment month, 1 dose of the study medication ulipristal acetate (UPA) will be given when the follicle is a certain size (approximately cycle day 10). Following this, there will be daily study visits for 7 days unless evidence of ovulation occurs earlier.
Receives: Drug: Ulipristal Acetate
Washout CycleNo interventionThe month following this first treatment month (washout-cycle),there will be no study visits during this menstrual cycle but there will be contact with study staff (1 or 2 times) by telephone or email to discuss any health changes that are experiencing.
UPA + COCActive comparatorDuring the second treatment month, 1 dose of the study medication ulipristal acetate (UPA) will be given when the follicle is a certain size (approximately cycle day 10) and then 2 days later start birth control pills. Following this, there will be daily study visits for 7 days unless evidence of ovulation occurs earlier.
Receives: Drug: Ulipristal Acetate; Drug: Levonorgestrel (LNG)/Ethinyl estradiol birth control pill

What is being measured

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

  1. Number of Participants With Follicle Rupture

    Following dosing with UPA, subjects underwent daily visits with ultrasound monitoring until evidence of follicle rupture (complete disappearance or >50% reduction of the mean size of the leading follicle).

    Measured: within 5 days of taking the study drug

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ulipristal Acetate in people with Contraception, run by Oregon Health and Science University at 1 site in United States.

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 4 inclusion and 7 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 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Follicle Rupture (time frame: within 5 days of taking the study drug). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Nov 2019.
