About this study

Non-invasive preimplantation genetic testing for aneuploidy (NiPGT-A) is an emerging approach that analyzes embryonic cell-free DNA (cfDNA) released into the spent culture medium (SCM) to assess chromosomal status without performing trophectoderm biopsy. This technique has the potential to reduce procedural invasiveness and eliminate biopsy-related risks while providing additional information for embryo selection in assisted reproductive technology (ART). However, the clinical value of NiPGT-A remains uncertain because available evidence is limited and largely derived from observational studies, with few studies reporting live birth outcomes.

This prospective observational study aims to evaluate the correlation between NiPGT-A results and clinical outcomes after single blastocyst transfer in patients with a favorable prognosis undergoing IVF/ICSI treatment. In this study, embryos with good morphological quality will undergo non-invasive sampling of spent culture medium for cfDNA analysis. NiPGT-A results will be categorized into four groups: no result, euploid, mosaic, and aneuploid. The study will compare pregnancy and birth outcomes across these groups to determine the clinical utility of NiPGT-A in embryo selection strategies.

Read the detailed description

Background and Rationale:

Preimplantation genetic testing for aneuploidy (PGT-A) using trophectoderm biopsy has been widely used in IVF to improve embryo selection. However, the invasive nature of embryo biopsy raises concerns about potential impacts on embryo viability and limits its routine use in certain patient populations. Non-invasive preimplantation genetic testing for aneuploidy (NiPGT-A) has been proposed as an alternative approach that analyzes cell-free DNA (cfDNA) released by the embryo into the spent culture medium (SCM) during in vitro development.

Several studies have demonstrated that cfDNA in SCM can reflect embryonic chromosomal status, but the concordance between NiPGT-A results and trophectoderm biopsy remains variable and influenced by factors such as sampling timing, maternal DNA contamination, embryo mosaicism, and laboratory protocols. Additionally, cases have been reported where embryos classified as aneuploid by NiPGT-A resulted in healthy live births, raising concerns about potential misclassification and highlighting the need for further clinical validation.

Recent research has suggested that NiPGT-A may be more valuable when used as a complementary tool to embryo morphology rather than as a direct replacement for biopsy-based PGT-A. Some studies have also reported that embryos with low or undetectable cfDNA levels in the culture medium may have favorable developmental potential, suggesting that cfDNA characteristics themselves could be associated with embryo viability.

Given the limited clinical evidence, particularly regarding live birth outcomes, further prospective studies are needed to clarify the relationship between NiPGT-A results and reproductive outcomes.

Study Objectives:

The primary objective of this study is to evaluate the correlation between clinical outcomes and NiPGT-A results in patients with favorable prognosis undergoing single blastocyst transfer.

A secondary objective is to explore criteria for embryo selection that combine NiPGT-A results with embryo morphological assessment.

Study Design:

This study is a prospective observational study conducted at My Duc Hospital (Tan Binh and Phu Nhuan centers) in Vietnam. A total of approximately 200 patients with favorable prognosis undergoing IVF/ICSI treatment will be enrolled. Eligible patients are women younger than 35 years with good ovarian response and at least four good-quality embryos on day 3.

Procedures:

Controlled ovarian stimulation will be performed using a standard antagonist protocol. Oocyte retrieval will be followed by intracytoplasmic sperm injection (ICSI), and embryos will be cultured to the blastocyst stage.

On day 5, the best-quality blastocyst (grade 1 or 2) from each patient will be selected. Approximately 10 µL of spent culture medium will be collected for NiPGT-A analysis without performing embryo biopsy. The embryo will then be cryopreserved using vitrification according to standard laboratory procedures.

Cell-free DNA extracted from the spent culture medium will undergo whole genome amplification (WGA) followed by next-generation sequencing to detect chromosomal copy number abnormalities. NiPGT-A results will be categorized into four groups: (1)No result (WGA failure); (2) Euploid; (3) Mosaic; (4) Aneuploid.

Importantly, NiPGT-A results will be blinded to clinicians and patients during the study and will not influence clinical decision-making. Embryo selection for transfer will be based solely on morphological assessment according to routine clinical practice. Frozen embryo transfer will be performed in a hormonally prepared cycle. Pregnancy testing will be conducted 10-14 days after embryo transfer. Ultrasound confirmation of clinical pregnancy will be performed approximately 3 weeks later. Participants will be followed throughout pregnancy and delivery using the hospital clinical database.

Outcome Measures:

Primary Outcome: Ongoing pregnancy or live birth rate after single blastocyst transfer, compared across the four NiPGT-A result groups.

Secondary Outcomes: Positive β-hCG rate, Biochemical pregnancy rate, Clinical pregnancy rate, Miscarriage rate, and prenatal ultrasound findings, including nuchal translucency measurement.

Statistical Analysis:

Continuous variables will be summarized using mean ± standard deviation or median with interquartile range. Categorical variables will be presented as percentages. Comparisons between groups will be performed using chi-square tests or Fisher's exact tests where appropriate. Statistical significance will be defined as p < 0.05. Data analysis will be conducted using R software (version 4.3.0).

Ethical Considerations:

The study uses spent embryo culture medium that would otherwise be discarded during routine IVF laboratory procedures. Collection of the medium does not involve embryo biopsy and does not interfere with embryo development, cryopreservation, or embryo transfer procedures.

Participation in the study does not alter standard clinical care, and NiPGT-A results are not used for clinical decision-making. All participants will provide written informed consent, and patient confidentiality will be strictly maintained.

What participants receive

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

Study groups in NCT07700602
Study groupRoleWhat they receive
No Result (WGA Failure) NiPGT -AEmbryos classified as having no NiPGT-A result due to unsuccessful whole genome amplification (WGA) of cell-free DNA obtained from the spent culture medium. These embryos are selected for transfer based solely on morphological assessment. Clinical outcomes after single frozen embryo transfer will be evaluated in this group.
Euploid NiPGT-AEmbryos classified as euploid based on NiPGT-A analysis of cell-free DNA obtained from the spent culture medium. Embryo selection for transfer is based only on morphological criteria according to routine clinical practice, and NiPGT-A results are blinded during treatment. Clinical outcomes will be compared with other NiPGT-A result groups.
Mosaic NiPGT-AEmbryos classified as mosaic according to NiPGT-A analysis of cell-free DNA from the spent culture medium. As in other groups, embryo transfer decisions are based solely on morphological evaluation, and NiPGT-A results are not used for clinical decision-making during the study.
Aneuploid NiPGT-AEmbryos classified as aneuploid according to NiPGT-A analysis of cell-free DNA obtained from the spent culture medium. Embryos included in this cohort are transferred based on morphological assessment without knowledge of NiPGT-A results. Clinical outcomes will be analyzed and compared with other groups.
