Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 42 years
  • Women only
  • No healthy volunteers
  • Adult

Who may be able to join

  • All patients medically cleared to do a fresh or frozen embryo transfer.
  • Age up to 42 years

Who cannot join

  • microsurgical epididymal sperm aspiration (MESA) and Testicular sperm extraction (TESE) patients
  • At least one partner carrier of a chromosomal or genetic disease
  • Abnormal ovarian reserve, defined as follicle stimulating hormone (FSH) of >10 IU/L on day 2-4 of the cycle and anti-mullerian hormone (AMH) < 1ng /ml (If only one of the two parameters altered then patients is acceptable). This is based on Mandy Katz abstract at American Society for Reproductive Medicine (ASRM) 2011 where they showed that these patients have 35% chance of having no euploid embryos - They are excluded only to make the study size smaller, otherwise, if an euploid embryo is found in these patients, they implant as well as patients with normal ovarian reserve. Not all centers do AMH testing - we recommend first to run FSH and only test AMH if FSH is abnormal.
  • Egg donor cycle (sperm donor is acceptable)
  • Gender selection cycles
  • Thaw cycles

About this study

Official title: Comparison of Standard ART Practice vs. Trophectoderm Biopsy, Whole Chromosome Analysis by Next Generation Sequencing, and Replacement of a Single Euploid Embryo

We propose to perform a clinical randomized trial to evaluate the effect of blastocyst biopsy and whole chromosome analysis by Next Generation Sequencing (NGS) in comparison to standard Assisted Reproductive Technologies (ART) methods on on implantation rates, miscarriage rates, and pregnancy rates.

This will be three studies into one: a) a comparison of treatment (NGS) and no treatment, b) a non-selection study based on the control group for which we will replace without knowing the ploidy of the embryos, but we will know it later, c) a retrospective study about the use of Mitochondrial DNA as a selection tool.

Read the detailed description

Patients following the inclusion criteria will be randomized into two groups:

  1. Control group: All blastocyst embryos will be biopsied on day 5/6, but the biopsies will be frozen and will not be analyzed before replacement. Blastocyst embryos will be vitrified for future frozen embryo transfer (FET) cycle. Patients will have a single hatching blastocyst (*) thawed and transferred into the uterus in a FET cycle based on standard embryo quality assessment without NGS. After transfer, all biopsied samples will be analyzed (the replaced embryo also, in order to do a non-selection study). If patients in the control group do not have a pregnancy to term from that FET cycle, euploid frozen blastocysts will be thawed and transferred on the next FET transfer.
  2. Test group: All blastocyst embryos will be biopsied on day 5/6, and the biopsies will be analyzed using NGS. (*) and Biopsied blastocyst embryos will be vitrified for a future frozen embryo transfer (FET) cycle. Patients will have a single hatching euploid blastocyst (*) thawed and transferred into the uterus in a FET cycle (*) Hatching blastocysts as described by Gardner and Schoolcraft (1999)

The Primary efficacy endpoint of comparing the study group with the control will be ongoing implantation rate (# fetus reaching 2nd trimester / # embryos replaced).

All biopsied embryos from the test and control group will have their mitochondrial DNA analyzed, but that information will not be used for purposes of choosing embryos for replacement. Retrospectively but blindly (see blinding of results section), the information will be used at the end of the study to determine which embryos have a higher chance of implanting. If at that point the participating patients have remaining embryos frozen, they will be able to use that information for purposes of embryo selection.

What is being measured

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

  1. improvement in ongoing implantation rates

    We foresee a significant increase in ongoing implantation rates in the Test group compared to the Control group based on several studies showing about a 50% improvement of implantation rates after Preimplantation Genetic Diagnosis (PGD) with blastocyst biopsy and comprehensive chromosome analysis techniques The center participating in the study has an average 41.5% implantation rate of blastocysts in patients 35-39 years of age without PGD. Assuming that NGS will increase the detection power of chromosome abnormalities, we expect a higher implantation rate in the test group.

    Furthermore, we expect a 6% miscarriage rate in the Test group, based on extensive data from array comparative genomic hybridization (aCGH) results (Hodes-Wertz et al. 2012), while about 21% in the Control group based on Society for Assisted Reproductive Technologies (SART) data (ages 35-40, SART 2011).

    Measured: When a fetal heartbeat is detected for each patient. (8 weeks after implantation).

Secondary outcomes (1)

  1. Determine specificity and sensitivity rates

    The pregnancy outcome of Controls patients with euploid embryos replaced will be compared to that of control patients with aneuploid embryos replaced. This will give us the specificity of the test (false positive rate) by obtaining the ongoing pregnancy rate of cycles with aneuploid embryos replaced, and the sensitivity of the test (false negative rate) by obtaining the miscarriage rate and ongoing pregnancy rate of cycles with euploid embryos replaced.

    Measured: During a pregnancy term

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 2 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 9 Sep 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 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

improvement in ongoing implantation rates (time frame: When a fetal heartbeat is detected for each patient. (8 weeks after implantation).). 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 NCT01946945, which also lists 18 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 9 Sep 2014.
