About this study

Official title: The Clinical Efficiency of Transcriptome-based Endometrial Receptivity Assessment (Tb-ERA) in Chinese Patients With Recurrent Implantation Failure (RIF)

In order to further explore the clinical utility of endometrial receptivity array in patients with repeated implantation failure, the patients divide into the experimental group or the control group. In the experimental group, those patients undergo endometrial receptivity array. In the control group, those patients do not receive any treatment before next cycle of transfer. In the experimental group, according to the results of endometrial receptivity array, the transplantation time will be adjusted and retransplantation will be carried out. Statistical analysis of the two groups of primary endpoint and secondary endpoint are done.

Read the detailed description

In the field of assisted reproduction techonology, there are still 10% of patients with repeated implantation failure. In order to further explore the clinical utility of endometrial receptivity array in patients with repeated implantation failure, the patients divide into the experimental group or the control group. In the experimental group, those patients undergo endometrial receptivity array. In the control group, those patients do not receive any treatment before next cycle of transfer. In the experimental group, according to the results of endometrial receptivity array, the transplantation time will be adjusted and retransplantation will be carried out. In the control group, no intervention will be performed. Statistical analysis of the two groups of primary endpoint (clinical pregnancy rate) and secondary endpoint (endometrial implantation window evaluation results, embryo implantation rate, biochemical pregnancy rate, early abortion rate, ectopic pregnancy rate) are done. Through the comparative analysis of clinical outcomes to verify the clinical efficacy of endometrial receptivity analysis in patients with repeated implant failure, this method will provide a new treatment for repeated implant failure population.

Questions about this trial

What is this clinical trial studying?

A study testing Endometrium biopsy in people with Endometrial Receptivity and Repeated Implantation Failure, run by ShangHai Ji Ai Genetics & IVF Institute at 1 site in China.

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 4 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 26 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Clinical pregnancy rate (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04497558, which also lists 3 linked publications.

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 26 Feb 2025.
