About this study

Official title: Intrauterine Contraception for Adolescents Aged 14 to 18: A Multi-center Randomized Controlled Feasibility Trial of Levonorgestrel-releasing Intrauterine System Compared to the Copper T 380A

This is a pilot study to determine the feasibility for a randomized controlled trial of two forms of intrauterine contraception: the Levonorgestrel intrauterine system (LNG-IUS) and the Copper T 380A.

Read the detailed description

Teenagers have the highest percentage of unintended pregnancies, and often struggle to comply with daily methods of contraception. The intrauterine device (IUD) provides safe, long-term protection and rates highly for patient satisfaction. It also does not require repeat prescriptions or clinic visits, making it a potentially attractive method among teens. However, in adolescent populations, there is both a lack of information about the IUD, as well as few studies that have examined the use of these devices. This study will examine whether a larger scale study on this topic is feasible. IT will address the feasibility of recruiting, consenting, screening, enrolling, randomizing, and retaining adolescents randomized to the LNG-IUS or Copper T 380a.

What participants receive

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

  • Levonorgestrel-releasing intrauterine device (LNG-IUS)Device

    Also called Mirena IUD

    Teens are randomly assigned to receive the LNG-IUS after completing a screening visit.

  • Copper T380A intrauterine device (CuT380A)Device

    Also called Paraguard IUD

    Teens are randomly assigned to Copper T380 after the screening visit

Study groups in NCT00653159
Study groupRoleWhat they receive
Mirena IUD [LNG-IUS]Active comparatorParticipants in this arm had a Levonorgestrel-releasing intrauterine device (LNG-IUS), also known as the Mirena IUD, inserted within the first 5 days of the adolescent's menstrual cycle, at least 7 weeks after a vaginal or cesarean delivery or second-trimester abortion or at least 3 weeks after a first-trimester abortion. For participants who had used depot-medroxyprogesterone acetate, insertions occurred at least 6 months after the participant's last injection. Participants were blinded to the device type; however, investigators and research assistants were not.

What is being measured

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

  1. Retention Rate

    Percentage of participants who completed the final visit (i.e., not subject to early termination or loss to follow-up)

    Measured: 6 months

Secondary outcomes (4)
  1. Heavy Bleeding Rates

    Rates of participants experiencing heavy bleeding among teens randomized to the LNG-IUS or Copper T 380A.

    Measured: 6 months

  2. Pregnancy Rates

    Proportion of subjects who became pregnant within 6 months of IUD insertion

    Measured: 6 months

  3. Expulsion Rates

    Rates of partial or complete expulsion for teens randomized to the LNG-IUS or Copper T 380A. Patients experiencing partial expulsion had IUDs visible on speculum exam. Complete expulsion is characterized by complete evacuation of the IUD.

    Measured: 6 months

  4. Device Satisfaction Rates

    Satisfaction rate is the proportion of subjects who report being "happy" or "very happy" with their assigned intrauterine contraceptive method on the date of their 6 month study visit.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levonorgestrel-releasing intrauterine device (LNG-IUS) and Copper T380A intrauterine device (CuT380A) in people with Contraception, run by University of Chicago at 2 sites 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 4 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 23 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 18 Oct 2012). 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?

Retention Rate (time frame: 6 months). 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 23 Feb 2023.
