About this study

Official title: Oral Contraception and Ovarian Suppression in Women With Different Weights

This study proposes a double blind randomized clinical trial to include normal weight and obese women who have normal ovulatory function at baseline; the investigators will randomize women to 2 widely used OCs and evaluate ovarian follicle development and circulating progesterone to assess ovarian suppression during OC use.

Read the detailed description

There is a large gap between lowest expected failure rates of about 1.5% and typical use failure rates of about 7% per year. This gap may be due to incorrect use or to decreased oral contraceptive (OC) effectiveness in population subgroups. Recent reports suggest greater OC failure among heavier women, particularly those using the lowest doses. The prevalence of obesity in the US population has recently increased to about 23% in women aged 20-29, peak years for OC use. OC physiology and effectiveness have not been evaluated in obese women.

What participants receive

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

  • Low dose formulationDrug

    Also called Low dose

    Participants are randomized to either Portia (levonorgestrel/ethinyl estradiol tablets, United States Pharmacopeia (USP)0.15 mg/0.03 mg or Lessina (levonorgestrel/ethinyl estradiol tablets, USP 0.1 mg/0.02 mg) for 3 months use.

    Dose formula contains 20 ug of ethinyl estradiol (EE) and 100 ug of levonorgestrel (LN) per tablet.

  • High dose formulationDrug

    Also called High dose

    Participants are randomized to either Portia (levonorgestrel/ethinyl estradiol tablets, United States Pharmacopeia (USP)0.15 mg/0.03 mg or Lessina (levonorgestrel/ethinyl estradiol tablets, USP 0.1 mg/0.02 mg) for 3 months use.

    Dose formula contains 30 ug of ethinyl estradiol (EE) and 150 ug of levonorgestrel (LN) per tablet.

What is being measured

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

  1. Risk of Oral Contraceptive (OC) Failure Due to Less Contraceptive-mediated Ovarian Suppression.

    Perpendicular diameter, ethinyl estradiol, and progesterone values were used to create Hoogland Scores. Hoogland Scores were used to assess ovarian suppression during OC use. The Hoogland Score comprises 6 grades (Because of small numbers, grades 5 and 6 were combined):

    1. no activity
    2. potential activity
    3. nonactive follicle-like structure
    4. active follicle-like structure
    5. luteinized unruptured follicle
    6. ovulation

    Each participant received a score from 1-6 to indicate the level of ovarian suppression; total number of participants were tallied for each Hoogland score.

    Measured: Up to 8 biweekly visits from start of OCP therapy

Secondary outcomes (2)
  1. Lipid or Carbohydrate Metabolism in Obese Versus Normal Weight Oral Contraceptive (OC) Users at Baseline and Exit Visit (12-16 Weeks OC Exposure).

    Measured: Screening (baseline) and follow-up 1 (exit)

  2. Pharmacokinetics of 15 Obese Weight and 15 Normal Weight Women on Combined Oral Contraceptives.

    Measured: 24 hours during week 3 of follow-up cycle

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Low dose formulation and High dose formulation in people with Ovarian Suppression, run by Columbia 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 9 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 30 Apr 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 14 Jun 2011). 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?

Risk of Oral Contraceptive (OC) Failure Due to Less Contraceptive-mediated Ovarian Suppression. (time frame: Up to 8 biweekly visits from start of OCP therapy). 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 NCT00827632, 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 30 Apr 2019.
