About this study

The objective of the study is to gain a better understanding of the gene expression changes in the endometrial biopsy especially whether the endometrium has reached a receptive status, i.e. the implantation window, or not.

Read the detailed description

The endometrium goes through huge gene expression changes during a cycle, the cells are transformed, the mucous membrane thickens, then loosens, and finally sheds. In this process, the expression of the genes also goes through significant changes, which can be determined from a small tissue sample.

Endometrium biopsy samples can be used for endometrium phasing. A question of the study is the feasibility of using for endometrium phasing beside endometrium tissue biopsy also samples generated by endometrium lavage. The advantage of this latter method is that it is minimally invasive, it does not cause haemorrhage and has minimal side effects. In some selected cases endometrial lavage will be performed on the same day with endometrial tissue sampling together with the drawing of a peripheral blood sample.

A list of potential biomarkers was proposed from the meta-analysis of published gene expression datasets. From the endometrium derived samples, RNA will be isolated and gene expression biomarkers will be measured. Expression profiles will be compared to published reference samples.

What participants receive

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

  • endometrium biopsyOther

    All patients will have endometrium biopsy.

  • endometrium lavageOther

    In some selected cases biopsy is preceded by endometrium lavage.

  • repeated endometrium lavageOther

    Endometrium lavage is repeated during the same cycle.

Study groups in NCT04052464
Study groupRoleWhat they receive
endometrium biopsy onlyIn these cases, only endometrium biopsy is investigated for the selected biomarkers gene expression profile.
Receives: Other: endometrium biopsy
endometrium lavage followed by endometrium tissue biopsyIn these cases before the endometrium tissue biopsy, an endometrial lavage is performed and from both samples, the selected biomarkers gene expression profile are investigated.
Receives: Other: endometrium biopsy; Other: endometrium lavage
serial endometrium lavage followed by endometrium biopsyIn these cases before the endometrium tissue biopsy, at different days endometrial lavage samples are taken. From all samples, the selected biomarkers gene expression profile are investigated.
Receives: Other: endometrium biopsy; Other: repeated endometrium lavage

What is being measured

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

  1. gene expression profile

    the endometrium derived samples are measured for the mRNA level expression of a selected list of biomarkers as it follows: ABCC3, ACTB, ADAMTS2, ADAMTS8, ARG2, ASPN, B2M, BAMBI, C10orf10, C1QTNF6, C2CD4A, CCDC71L, CD55, CEBPD, CP, CRISP3, CTHRC1, CYP24A1, CSRP2, DDX52, DPP4, DUOX1, DUOXA1, EDNRB, FCER1G, G0S2, GADD45G, GNG2, GNG4, GPX3, GRAMD1C, GREM2, GZMA, HPGD, HTR2B, IGFBP1, IGFBP3, IGFBP6, IL1B, IRX3, ITGA2, ITGB6, KAL1, KCND2, KCNK3, LCP2, LEFTY2, LRP4, LTBP2, LUM, MAOA, MAP2K6, MFSD4, MMP10, MS4A7, MT1M, MUC16, NID2, NNMT, OPRK1, PAEP, PDE4B, PHLDB2, PKHD1L1, PLAT, PLD1, POLR2A, PPIA, RARRES1, RDH10, RGS1, RHOB, RHPN2, RIMKLB, SGIP1, SLAIN1, SLC15A1, SLC15A2, SLC1A1, SLC26A7, SLC5A3, SOD2, SPP1, SYT11, TBP, TCN1, TFPI2, THBS1, TIMP3, TMC5, TMED6, TNFRSF11B, TSPAN8

    Measured: measurements are performed within 3 weeks after samples are shipped to the laboratory

  2. endometrium phase assesment

    based on the gene expression profile endometrium samples are phase assigned based on published reference samples

    Measured: phase assignment is performed within two weeks after the measurements are performed.

Questions about this trial

What is this clinical trial studying?

An observational study of Infertility, Female and IVF, run by Prelife Kft.

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 4 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: finished, as of the sponsor's last update on 9 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

gene expression profile (time frame: measurements are performed within 3 weeks after samples are shipped to the laboratory). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Aug 2019.
