What participants receive

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

  • Endometrial injuryProcedure or surgery

    Evaluate the position and size of the uterus by transabdominal ultrasonography, with the bladder comfortably full.

    Identify the cervix with a disposable speculum. Open one sealed opaque envelope for allocation.

    Endometrial injury:

    • Slide the Pipelle de Cornier® (Laboratoires Prodimed, Neully-En-Thelle, France) gently through the cervix up to the uterine fundus. Transbadominal ultrasound might be used to confirm position.
    • Draw back the piston to the end of the biopsy cannula until it locks creating a negative pressure.
    • Sweep the uterine fundus slowly several times up to the internal orifice of the cervix, using regular to-and-fro movements while rotating the sampler to include the whole uterine cavity in the specimen, for 30 seconds or until participant ask for stopping.
  • Control groupProcedure or surgery

    Also called Sham procedure

    The investigator will dry the cervix with gauze and forceps for for 30 seconds or until participant ask for stopping.

What is being measured

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

  1. Live Birth

    The complete expulsion or extraction from its mother of a product of fertilization, irrespective of the duration of the pregnancy, which, after such separation, breathes or shows any other evidence of life, such as heart beat, umbilical cord pulsation, or definite movement of voluntary muscles, irrespective of whether the umbilical cord has been cut or the placenta is attached.

    Note: All allocated women will be used as denominator when assessing live birth rate.

    Measured: 1 year

Secondary outcomes (8)
  1. Clinical Pregnancy

    Pregnancy diagnosed by ultrasonographic visualization of one or more gestational sacs or definitive clinical signs of pregnancy. It includes ectopic pregnancy. Multiple gestational sacs are counted as one clinical pregnancy.

    Note: All allocated women will be considered when assessing clinical pregnancy rate.

    Measured: 3 months

  2. Ongoing Pregnancy

    At least one fetus with heart beat after 12 weeks of gestational age.

    Note: All allocated women will be considered when assessing ongoing pregnancy rate.

    Measured: 6 months

  3. Miscarriage

    Loss of a clinical pregnancy before 20 completed weeks of gestational age (18 weeks after fertilization).

    Note: All allocated women will be considered when assessing miscarriage rate.

    Measured: 9 months

  4. Implantation Rate

    The number of gestational sacs observed divided by the number of embryos transferred.

    Measured: 3 months

  5. Endometrial Thickness

    The maximum distance perpendicular to the inter-endometrial interface from the endometrium-myometrium interface of the anterior to the posterior wall of the uterus assessed in the sagittal plane. This outcome will be assessed when at least one follicle ≥ 17mm is observed.

    Measured: 1 month

  6. Endometrial Volume

    The total volume of endometrial tissue assessed by three-dimensional ultrasonography. This outcome will be assessed when at least one follicle ≥ 17mm is observed.

    Measured: 1 month

  7. Three-dimensional Doppler Indices From Endometrium (VFI)

    Vascularization index (VI), flow index (FI) and vascularization-flow index (VFI) assessed from endometrium using three-dimensional Power Doppler ultrasonography. This outcome will be assessed when at least one follicle ≥ 17mm is observed.

    Only VFI was reported as it is a combination of VI and FI (VFI = VI*FI/100), and currently there are several concerns about the validity of these indices.

    Such indices have no scale.

    Measured: 1 month

  8. Procedure Related Pain

    Pain will be assessed using a Visual Analogue Scale (VAS). We will use a 10 cm length horizontal line, anchored by word descriptors at each end: "No Pain" = 0 cm and "Very Severe Pain" = 10 cm.

    This outcome will be assessed in both groups, just after endometrial injury or sham procedure.

    Measured: Immediately after procedure

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Endometrial injury in people with Infertility, run by University of Sao Paulo at 1 site in Brazil.

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 3 inclusion and 1 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: stopped early, as of the sponsor's last update on 17 Feb 2014. 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 Brazil. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 17 Feb 2014). 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?

Live Birth (time frame: 1 year). 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 NCT01132144, 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 17 Feb 2014.
