Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
It has been already demonstrated the existence of transcriptomic profiles that are characteristics of each endometrial phase: pre-receptive, receptive and post-receptive. 'Igenomix' group developed a molecular tool able to classify the endometrium based on its transcriptomic profile, the Endometrial Receptivity Analysis (ERA). This molecular tool analyses, by next generation sequencing (NGS), the expression of 248 genes related to implantation coupled to a computational predictor to identify the specific transcriptomic profile for each endometrial stage. This test has been applied at clinical level from 2010, helping to synchronize a viable embryo with a receptive endometrium through the personalized embryo transfer (pET). It aims to improve clinical implantation by personalizing, diagnosing, and synchronizing the endometrial factor.
Our goal in this project is to investigate at what extent, if any, the analysis of the endometrial factor, at receptivity level, in patients at their first in vitro fertilization (IVF) cycle improves their clinical outcome through a personalized embryo transfer by the ERA test in comparison to embryo transfer(FET).

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The ERA test allows to transfer in a personalized manner by synchronizing the embryo with the WOI of the patient. Nowadays, it has been published that around 30% of patients present 1 or 2 days of displacements and about 50% show 12 hours of displacement.
The ERA has been broadly applied around the world in order to increase the probabilities of recurrent implantation failure patients becoming pregnant. Recently, a multicenter international open-label randomized controlled trial comparing personalized embryo transfer guided by the ERA test versus frozen and fresh embryo transfer was carried out at first appointment of infertile patients undergoing IVF. The current project aims to assess in a randomized way the potential improvement on the clinical outcome of Chinese infertile patients at their first IVF cycle by diagnosing, personalizing and synchronizing the endometrial factor with the ERA. To do that, only the outcomes of the first single embryo transfers performed after the inclusion of each patient will be considered.
Considering a 30% of possible drop-outs, a total of 714 patients will be recruited (357 randomized in each group). They will be allocated on a balanced way (assigned by chance like the flip of a coin) in one of the two arms described below. Reproductive outcomes (defined following The International Glossary on Infertility and Fertility Care, 2017) will be compared between the two groups.
Data exported from the source documents will be duly codified and treated in order to protect the clinical and personal information of participants in accordance with the current local legislation.
All the statistical analysis performed on the data, as well as the procedures, will be registered in a detailed Statistical Analysis Plan (SAP) that will be developed during the study and before starting data analysis.
An interim analysis of this data is planned once 50% of the recruitment has been achieved. Besides and at that same moment, the study will be overseen by an independent Data Monitoring Committee.
All the statistical procedures will be done systematically by both, intention to treat analysis (ITT) and per protocol analysis (PP). The ITT analysis will include all randomized patients recruited and assigned to one of two groups after endometrial biopsy collection. The PP analysis will be applied to those patients who adequately follow the protocol assigned according to their group and arm and in whom the transfer of the good quality blastocyst is performed.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention group(pET)
Personalized embryo transfer of a single vitrified blastocyst in a HRT cycle according to the ERA test results.
ERA
Before the randomization, Endometrial Fluid (EF) and Endometrial Biopsy (EB) samples will be collected from all participants. EF will be obtained by aspiration immediately prior to the EB after around 120 hours of progesterone (P) impregnation following the standard HRT cycle. The results of the ERA test will be provided to participants and their gynecologists for the personalized embryo transfer.
Control group(FET)
Frozen embryo transfer of a single vitrified blastocyst in a HRT cycle according to the clinical standard practice.
ERA
Before the randomization, Endometrial Fluid (EF) and Endometrial Biopsy (EB) samples will be collected from all participants. EF will be obtained by aspiration immediately prior to the EB after around 120 hours of progesterone (P) impregnation following the standard HRT cycle. The results of the diagnosis will not be disclosed with the patients randomized into this arm nor with their gynecologists.
