About this study

The investigators propose to perform a clinical randomized trial to evaluate the effect of a frozen-thawed embryo transfer and a fresh embryo transfer on pregnancy and implantation rates; with the added benefit of a blastocyst biopsy and whole chromosome analysis by Next Generation Sequencing (NGS).

Read the detailed description
  1. Fresh group: All embryos will be hatched on day 3. Patients will have hatching blastocysts (*) biopsied on day 5, analyzed by NGS, and will have one or two euploid embryo transferred on day 6, in the am. If more than two euploid blastocysts are available the one(s) to be transferred will be selected based on morphology (*). Any morulas developing to hatching blastocyst on day-6 will be also analyzed but vitrified for use in a future cycle.
  2. Frozen group: All embryos will be hatched on day 3. Patients will have hatching blastocysts (*) biopsied on day 5 or day 6, embryos will then be vitrified, analyzed by NGS, and will have one or two euploid embryo(s) thawed and transferred on a FET cycle, before noon. If more than two euploid blastocysts are available the one(s) to be transferred will be selected based on morphology (*). (*) Hatching blastocysts as described by Gardner and Schoolcraft (1999):

What is being measured

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

  1. Implantation rate

    determining whether a frozen or a fresh embryo transfer will improve implantation rate.

    Measured: 8 weeks after replacement

Secondary outcomes (1)

  1. Correlation of Mitochondrial DNA and implantation

    The second aim of this study is to determine retrospectively if mt DNA content is linked to implantation potential and if that is measurable by NGS. NGS provides the additional advantage that it can measure mitochondrial DNA, which it's content, seems to be inversely correlated with implantation (Fragouli et al 2013, ASRM).

    Measured: When a fetal heartbeat is detected (8 weeks after implantation)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PGD in people with Infertility, run by Reprogenetics at 1 site 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 1 inclusion and 7 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 17 Nov 2015. 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?

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: 8 weeks after replacement). 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 NCT02000349, which also lists 13 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 17 Nov 2015; AzTrials last refreshed its copy on 8 Nov 2026.
