Levonorgestrel-Intrauterine System (LNG-IUS) Insertion in the Postpartum Period

July 16, 2025 updated by: United States Naval Medical Center, Portsmouth

Levonorgestrel-Intrauterine System (LNG-IUS) Insertion in the Postpartum Period: A Prospective, Randomized Pilot Study of Three Time Intervals

The investigators study is a prospective randomized trial of women undergoing the levonorgestrel intrauterine system (LNG-IUS: Mirena©, Bayer) at three separate time periods: immediate post placental (IPP) defined as insertion within 10 min delivery of placenta, early post partum (EP) defined as insertion after 10 min but within 72hrs postpartum, or interval (INT) insertion defined as insertion after 6wks postpartum. This is a pilot study in preparation for a multicenter, prospective randomized study of long-acting reversible contraception in the postpartum period.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years to 45 years (Child, Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • All reproductive age women who express a desire for the LNG-IUS (Mirena©) at routine questioning at their 36-38 week prenatal appointment or upon admission to labor and delivery are eligible for our study.

Exclusion Criteria:

  • Contraindications to the LNG-IUS include: Pregnancy or suspicion of pregnancy, Congenital or acquired uterine anomaly including fibroids if they distort the uterine cavity, Postpartum endometritis within the past 3 months, Known or suspected uterine or cervical neoplasia or unresolved, abnormal pap smear, untreated acute cervicitis or vaginitis including bacterial vaginosis or other lower genital tract infections, acute liver disease or liver tumor, hypersensitivity to any component of the product, known or suspected carcinoma of the breast. Any of these conditions would exclude the patient from our study.
  • Delivery <36 weeks
  • Intrapartum chorioamnionitis (defined as maternal fever >100.4 and two of the following conditions: Maternal leukocytosis (greater than 15,000 cells/cubic millimeter), Maternal tachycardia (greater than 100 beats/minute), Fetal tachycardia (greater than 160 beats/minute), Uterine tenderness, Foul odor of the amniotic fluid
  • Postpartum Hemorrhage (defined as >500cc EBL for spontaneous vaginal delivery)
  • Cesarean delivery if randomized to IPP or EP placement

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Continuation Rates of the LNG-IUS when placed postpartum at three time periods
Time Frame: at 6 months
Determine if there is a difference in continuation rates at 6 months between participants who had the LNG-IUS placed at three different time periods: Immediate Postplacental (within 10 minutes from delivery of placenta), Early Postpartum (after 10 minutes but before 48 hours postpartum) , and Interval (after 6 weeks postpartum).
at 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Expulsion rate of the LNG-IUS when placed postpartum at three time periods
Time Frame: at 3 weeks
Determine if there is a difference in expulsion rates at the three different time periods of placement.
at 3 weeks
Pain at placement
Time Frame: at 1 minute
Determine if there is a difference pain as assessed with the Visual Analog Scale at the time of placement of the LNG-IUS at three time period: Immediate Postplacental, Early Postpartum, or Interval.
at 1 minute

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 1, 2009

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
