Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Diagnosis / Prognosis - niPGT-A
Other interventions - Morphology criteria

Active Comparator: Control group (group 1) - Deferred single day 6/7 blastocyst transfer with blastocyst selection according to morphology.

Experimental: Intervention group (group 2) - Deferred single day 6/7 blastocyst transfer with blastocyst selection according to the analysis of the spent culture media (niPGT-A).


Diagnosis / Prognosis: niPGT-A
Two scenarios should be considered according to the results in the SBM analysis:
The couple decides to transfer the blastocyst selected according to the SBM result (blastocyst prioritization system).
The couple decides to biopsy the blastocysts (if SBM results show low euploidy score). This PGT-A analysis will be offered for free but the outcome of these transfers will be excluded for the analysis per completed protocol. However, all transfers will be included in the intention-to-treat analysis.
In the exceptional case of getting a non-informative result for all the SBM analysed, the niPGT-A could be performed again on new SBM samples collected after an additional culture of the embryos for, at least, 8 hours.

Other interventions: Morphology criteria
Embryos for transfer will be selected by the only applicable technique, the assessment of morphology according to Gardner´s criteria, which is the most standardized method.

Eligibility
Key inclusion criteria
- Patients whose written informed consent approved by the Ethics Committee (EC) has been
obtained, after having been duly informed of the nature of the study and voluntarily
accepted to participate after being fully aware of the potential risks, benefits and
any discomfort involved.

- IVF patients intending to undergo deferred day 6/7 blastocyst SET for any medical
indication.

- All the oocytes/embryos from the cycle should follow the laboratory protocol described
in the study (embryo culture and vitrification on day 6/7).

- ICSI, IVF or ICSI/IVF performed in fresh own oocytes from couples not undergoing
PGT-A. Note: Donor sperm is allowed.

- Female age: 20-40 years, both included.
Minimum age
20 Years
Maximum age
40 Years
Sex
Females
Can healthy volunteers participate?
No
Key exclusion criteria
- Assisted hatching and artificial collapse before collecting SBM samples. Note: Both
procedures are allowed only after collecting the culture media sample.

- A known abnormal karyotype if the couple provides it at consultation. If not,
karyotype is not compulsory.

- Couples planning to undergo PGT-M or PGT-SR cases will be excluded.

- Surrogate pregnancy (in those countries where it is allowed).

- ERA test and embryo transfer according to ERA result.

- Time-lapse culture systems are not allowed after day 4 of culture.

- Presence of pathologies or malformations that affect the uterine cavity such as
polyps, intramural myomas = 4cm or submucosal, septum or hydrosalpinx during the
patient's participation in the study. Patients suffering these pathologies before or
after their inclusion in the study can participate if the pathology is corrected
before performing any study procedure.

- Any illness or medical condition that is unstable or which, according to medical
criteria, may put at risk the patient's safety and her compliance in the study.

Summary
Brief summary
Chromosomal aneuploidies are linked with spontaneous miscarriages and abnormal offspring in
human pregnancies. In addition, some types of aneuploidies are reported to prevent
implantation. Thus, there is a need to identify the embryos with highest implantation
potential on in vitro fertilization (IVF) programs.

Since embryo morphology and kinetics have a weak association with embryo ploidy,
trophectoderm biopsy plus Next-Generation Sequencing (NGS) is becoming a very popular
approach to determine the embryo chromosomal status. This technique is called Preimplantation
Genetic Testing for Aneuploidy (PGT-A). Although shown to be efficient, it is invasive for
the embryo, requires specific technical skills and it remains expensive. Therefore, the
development of a non-invasive, rapid and cheaper method for assessing embryo ploidy status
would represent a progress in the field of IVF.

The non-invasive approach has been explored by some groups that analyzed the Spent Blastocyst
Medium (SBM) where the embryo was incubated up to the time of transfer or freezing. In daily
routine, this media is discarded after finishing the culture of the embryo. Importantly,
though, this media reportedly contains traces of embryonic cell-free DNA (cfDNA) that can
represent the genetic load of the embryo.

On the basis of that, the hypothesis of this study is that embryo prioritization according to
the analysis of the embryonic cfDNA in the SBM could improve ongoing pregnancy rate in 10
percentual points compared to standard blastocyst transfer based on morphology.
