About this study

Official title: A Pilot, Observational, Prospective Study to Evaluate the Performance of CHLOE Algorithm on the Prediction of Blastocyst Formation in Women Undergoing In-vitro Fertilization

This is an observational, prospective, single-arm, multi-center, clinical study to evaluate the performance of CHLOE, an Artificial Intelligence (AI)-based software application, as adjunct information to support identifying embryos on Day 3 that are most likely to form blastocysts.

Read the detailed description

The study is an observational, prospective, single-arm, multi-center, clinical study in order to evaluate the performance of CHLOE, an Artificial Intelligence (AI)-based software application, as adjunct information to support identifying embryos on Day 3 that are most likely to form blastocysts on Day 5.

What participants receive

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

  • CHLOEDevice

    CHLOE is designed to automatically analyze events related to embryo development from Time Lapse Incubator (TLI) images and provide prediction on the likelihood of embryos developing to the blastocyst. This information can assist embryologists and IVF professionals in the selection of the most viable embryo for transfer or freezing, when there are multiple embryos deemed suitable.

What is being measured

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

  1. The association between the adjunct prediction using CHLOE of blastocyst outcome and the actual blastocyst outcome for a subset of good/fair embryos

    The prediction of blastocyst outcome using CHLOE algorithm, and the actual blastocyst outcome for a subset of good/fair embryos will be measured using odds ratio.

    Measured: 3 days

Secondary outcomes (3)
  1. The association between the adjunct prediction using CHLOE of blastocyst outcome and the actual blastocyst outcome for all embryos

    The prediction of blastocyst outcome using CHLOE algorithm, and the actual blastocyst outcome for all embryos will be measured using odds ratio.

    Measured: 3 days

  2. Blastocyst formation using traditional human morphology only for all embryos

    The prediction of blastocyst outcome using traditional human morphology only, and the actual blastocyst outcome for all embryos will be measured using odds ratio.

    Measured: 3 days

  3. Blastocyst formation based on the CHLOE algorithm prediction for a subset of good/fair embryos

    The prediction of blastocyst outcome using the CHLOE algorithm for each individual embryologist will be measured using odds ratio for a subset of good/fair embryos.

    Measured: 3 days

Questions about this trial

What is this clinical trial studying?

An observational study of Fertility Disorders, run by Fairtility at 3 sites in 2 countries.

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 9 inclusion and 7 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 5 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Israel. 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?

The association between the adjunct prediction using CHLOE of blastocyst outcome and the actual blastocyst outcome for a subset of good/fair embryos (time frame: 3 days). 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 5 Mar 2025.
