About this study

Official title: On Demand Contraception: Investigating Efficacy of Ulipristal Acetate Plus a COX-2 Inhibitor at Peak Fertility

This is an exploratory prospective study investigating if addition of a COX-2 inhibitor can increase efficacy of ulipristal in disrupting ovulation at peak fertility.

Read the detailed description

This is an exploratory prospective study investigating if addition of a COX-2 inhibitor can increase efficacy of ulipristal in disrupting ovulation at peak fertility. We will compare the proportion of women with ovulatory disruption after taking the study medications with those women's own placebo cycles and also to previously established/published rates of ovulatory disruption of ulipristal alone.9 Given the established efficacy of ulipristal during the follicular time period as well as the theoretical mechanism of meloxicam to disrupt cumulus-oocyte expansion is a late step in ovulation, we hypothesize that this medication could emerge as the best candidate for an oral on-demand contraceptive option.

What participants receive

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

  • Ulipristal Acetate 30 MG Oral TabletDrug

    Also called Meloxicam

    Each study participant will receive one dose of the study medication (ulipristal acetate 30mg plus meloxicam 15mg) at peak fertility in the treatment cycle.

What is being measured

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

  1. ovulatory disruption

    (1) no follicle rupture or (2) follicle rupture that was (a) not preceded within 24-48 hours by an LH peak, (b) preceded by a blunted LH peak (<21IU/L), and/or (c) followed by a luteal phase progesterone peak of <3ng/mL

    Measured: 8 weeks from start of study, approximately

Secondary outcomes (3)
  1. luteal hormone levels

    luteal hormone levels

    Measured: 8 weeks from start of study, approximately

  2. progesterone hormone levels

    progesterone hormone levels

    Measured: 8 weeks from start of study, approximately

  3. maximum follicle diameter

    maximum ovarian follicle diameter

    Measured: 8 weeks from start of study, approximately

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ulipristal Acetate 30 MG Oral Tablet in people with Contraception, run by Stanford 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 9 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 25 Jun 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

ovulatory disruption (time frame: 8 weeks from start of study, approximately). 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 NCT03354117, which also lists 1 linked publication.

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 25 Jun 2019.
