Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Preimplantation genetic diagnosis using next generation sequencing. Involves patient's biopsied embryos genetic analysis. Choice of the embryos for transfer was based on the PGD NGS results.
Duration: 12 hours of analysis
Frequency: Once in this investigation
Intervention code [1] 289909 0
Diagnosis / Prognosis
Comparator / control treatment
ICSI with preimplantation genetic diagnosis (PGD) vs standard treatment (ICSI without PGD). In control group selection of embryos for transfer was based on microscopic morphology analysis and rate of divisions analysis.

Summary
Brief summary
Our objective was to determine pregnancy rate after comprehensive chromosome screening (CCS) using PGD NGS in frozen embryo transfer cycles after blastocyst’s trophoectoderm biopsy. 40 patients who decided to undergo PGD on 24 chromosomes on blastocystes with vitrification and frozen embryo transfer were included in the study as an investigated group. As a control group we selected 74 cases which were comparable in age, anty-mullerian hormone level (AMH), antral follicle count (AFC) and causes of infertility. Only first IVF cycles were taken under consideration.

Public notes
We have been performing preimplantation genetic diagnosis (PGD) for many years now (using FISH method). As we decided to introduce a new and more reliable tool for PGD - next generation sequencing (NGS) we submitted appropriate application to Ethics Committee before enrolment of first patient. We didn't receive Committee consent but a notification that such agreement is not necessary in case of routine research like PGD. However, after our insistence we received a consent retrospectively in which the Committee explained that their had agreed although their agreement was not necessary in this case.
