About this study

Official title: Effect of Low Molecular Weight Heparin (Bemiparin) on Implantation Rate in Patients With Recurrent Implantation Failure Undergoing IVF/ICSI - A Prospective Randomized Clinical Trial

The objective of this study is to determine the effect of Bemiparin, a low molecular weight heparin, on implantation rate in women with unexplained recurrent implantation failure undergoing IVF/ICSI treatment.

Read the detailed description

Recurrent implantation failure (RIF), defined as failure of conception following three or more consecutive In Vitro Fertilization (IVF) cycles despite the transfer of good quality embryos, is a major cause of distress amongst infertile couples. While factors underlying implantation failure are many, most cases remain unexplained. In order to improve pregnancy outcomes and delivery rates in women with unexplained RIF, various investigational treatments have been proposed.

The investigators propose a prospective controlled randomized comparative study to evaluate the effect of Bemiparin on implantation rates in women with unexplained RIF. A total of 200 patients will be recruited and randomized between two groups. The study group will receive Bemiparin plus standard care; while the control group will receive only standard care. Treatment will start on the day following embryo transfer and will be continued until 12 weeks gestation in the event of pregnancy.

The primary objective is to determine the effect of Bemiparin on implantation rate in women with unexplained recurrent implantation failure.

What participants receive

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

  • Bemiparin sodiumDrug

    Also called Hibor

    Bemiparin sodium 3,500 IU will be started on the evening of the same day of embryo transfer and until the day of pregnancy test. If the test is positive, Bemiparin will be discontinued by the end of the 12th week of gestation.

What is being measured

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

  1. Implantation rate (%)

    Number of intrauterine gestational sacs observed by transvaginal ultrasonography divided by the number of transferred embryos

    Measured: Vaginal ultrasound at 8 weeks gestation

Secondary outcomes (4)
  1. Live birth rate (%)

    birth of live born

    Measured: Time of delivery up to 42 weeks gestation

  2. Ongoing pregnancy rate (%)

    Fetal heart beat seen by ultrasound at 20 weeks gestation

    Measured: Vaginal ultrasound at 20 weeks of gestation

  3. Clinical pregnancy rate (%)

    Fetal heart beat seen by ultrasound at 8 weeks gestation

    Measured: Vaginal ultrasound at 8 weeks gestation

  4. Total pregnancy rate (%)

    Positive hCG titer

    Measured: Up to 15 days from oocyte collection

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bemiparin sodium in people with Sterility, run by American University of Beirut Medical Center at 1 site in Lebanon.

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 6 inclusion and 12 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 20 Jul 2023. 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 Lebanon. 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?

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?

Implantation rate (%) (time frame: Vaginal ultrasound at 8 weeks gestation). 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 20 Jul 2023.
