What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to assist women who have experienced difficulties with embryo implantation during IVF treatments by studying the timing of the uterus lining's most receptive stage, known as the window of implantation (WOI). Researchers will use the ERA® test to identify this optimal time and the EMMA® test to examine the uterus's microbiome (bacterial environment). Women with previous failed embryo transfers, particularly those with at least one failed attempt using a good-quality embryo, will be suitable candidates. Participants will continue their IVF treatment, and samples will be collected to study these factors, but the test results will not be shared with them or their doctors.

As a Phase 2 trial, this study measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to significant research in IVF advancements.

Do I have to stop taking my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that no hormone replacement therapy (HRT) should be used in the biopsy and/or embryo transfer cycle, and intrauterine devices (IUDs) should not have been used within 3 months before sample collection.

What prior data suggests that the ERA® test is safe for assessing endometrial receptivity?

Research has shown that the ERA® test, which identifies the optimal time for embryo transfer, is generally safe as it involves no medications. The test examines a small tissue sample from the uterus, similar to a biopsy, a common procedure for collecting tissue for examination.

Studies have found that while the ERA® test does not guarantee higher pregnancy rates, it poses no major safety risks. Most reports focus on its effectiveness rather than safety concerns. As the test is diagnostic and drug-free, it has no serious side effects directly associated with it.

The test has been widely used and is approved for its intended purpose, indicating it is well-tolerated by patients. Participants typically experience only minor discomfort during the biopsy, akin to other standard biopsies.12345

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores a novel approach to understanding implantation failures in assisted reproductive technology (ART). Instead of introducing new drugs, this study uses the ERA® test to analyze the receptivity of the endometrium, which is crucial for successful embryo implantation. By collecting endometrial biopsies and fluid, the trial aims to identify the optimal window for implantation, potentially increasing success rates in patients with previous failures. This focus on personalizing treatment timelines makes it a promising development in reproductive medicine.

What evidence suggests that the ERA® test is effective for determining the window of implantation?

Research has shown that the ERA® test can identify the optimal time for embryo transfer by assessing uterine readiness. In this trial, participants will be divided into two groups based on their ERA® test results: those with a receptive endometrium and those with a non-receptive endometrium. Studies suggest that using ERA® to guide embryo transfers can improve pregnancy chances for some women, particularly those who have previously experienced implantation difficulties. The test pinpoints the best time for placing an embryo in the uterus. However, some experts believe more research is needed to confirm its effectiveness for everyone. Overall, ERA® aims to align embryo transfers with a woman's unique biological timing, potentially increasing the likelihood of a successful pregnancy.12678

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

1-2 months

Non-selection Phase

Participants follow their programmed IVF/ICSI treatment, undergo PGT-A testing, and have endometrial samples collected for ERA® and EMMA® tests.

1-2 months
1 additional visit for sample collection

Rescue Phase

For patients not achieving ongoing pregnancy, ERA® results may guide a personalized embryo transfer in a new HRT cycle.

Varies based on individual treatment cycles

Follow-up

Participants are monitored for clinical outcomes such as pregnancy and live birth rates.

Up to 13 months
