About this study

Official title: Fetal Genome Profiling After Non-Invasive Isolation of Trophoblast Cells

The objective of this study is to utilize trophoblast cells accumulating in the endocervical canal at the beginning of pregnancy for non-invasive prenatal testing. If we are able to validate that trophoblast cells obtained at an early gestational age can be reliably used for prenatal testing, there is great potential to improve early pregnancy management and counseling options for potential parents. The target population will be all women between the age of 18-45 undergoing care at the Center for Reproductive Medicine (CRM) in order to achieve a pregnancy.

Read the detailed description

The primary purpose of the study is to validate trophoblast retrieval and isolation from the cervix (TRIC) as a means of reliable non invasive prenatal genetic diagnosis (for both chromosomal abnormalities, as well as single gene defects).

The study population will be recruited from women, age 18 to 45, presenting to the Center for Reproductive Medicine (CRM) for medical care with the desire to become pregnant. Patients that achieve pregnancy will be invited by a physician to participate in the study. If prospective subjects agree to participate, they will meet with a co-investigator to go through the informed consent process.

Subjects will undergo a one-time non-invasive collection of trophoblast cells (trophoblast retrieval and isolation from the cervix, TRIC) at approximately 5-6 weeks of pregnancy as the experimental procedure for the study. TRIC is performed with ThinPrep kits using a cytobrush, the same method of Pap smear collection which is a routine part of prenatal care. The fetal trophoblast cells will then be isolated using immunomagnetic isolation. Once isolated, DNA fragmentation, fluorescent in situ hybridization (FISH), and single-cell PCR methods will be utilized to analyze the fetal genome at single nucleotide resolution. Any abnormal results identified by TRIC will be communicated to the subjects' by their physician in the office who will counsel them on the potential meaning of the results and recommend follow up testing to be ordered by their obstetrician to confirm results.

The cellular analysis from TRIC will then be compared to results obtained from CVS, amniocentesis, preimplantation genetic screening (PGS) and/or preimplantation genetic diagnosis (PGD) of the transferred embryo(s), or cytogenetic testing of fetal tissue in the event of miscarriage or pregnancy termination for validation. In the event that a patient does not undergo any of the aforementioned testing, TRIC results will be compared to birth outcomes.

Subjects will be followed via medical records through the final outcome of the pregnancy, whether termination of pregnancy, miscarriage, or live birth. If the pregnancy results in termination of pregnancy or miscarriage, cytogenetic testing of the fetus will be completed as standard care with the results compared to those obtained through TRIC testing. If the pregnancy results in live birth, basic neonatal information will be obtained via medical records, specifically whether the neonate is diagnosed with a disorder that can be identified through single gene testing (see attached table).

What participants receive

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

  • Fetal Genome Profiling.Diagnostic test

    Once pregnancy is achieved, patients will undergo non-invasive collection of trophoblast cells (trophoblast retrieval and isolation from the cervix, TRIC) at an early gestational age, approximately 5-6 weeks. The patient will also be screened with blood work for carrier status for genetic conditions.

Fetal Genome ProfilingOtherTrophoblast cells will be collected from the cervix approximately 5-6 weeks once pregnancy is achieved.
Receives: Diagnostic Test: Fetal Genome Profiling.

What is being measured

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

  1. Occurrence of chromosomal anomalies as detected via fetal genome analysis of trophoblast cells

    Trophoblast cells isolated from the cervix will be used to detect chromosomal anomalies occurrences as a means of non-invasive prenatal screening.

    Measured: 6 weeks post pregnancy

Secondary outcomes (1)
  1. Occurrence of chromosomal anomalies detected via trophoblast cell analysis as compared to occurrence of chromosomal anomalies detected via preimplantation genetic testing (PGT), chorionic villi sampling (CVS), amniocentesis, or cytogenetic results.

    Occurrence of chromosomal anomalies detected via trophoblast cells analysis will be compared to the occurrence of chromosomal anomalies detected via either PGT, CVS, amniocentesis, or cytogenetic which ever is available for validation.

    Measured: 16 weeks post pregnancy

Questions about this trial

What is this clinical trial studying?

A study testing Fetal Genome Profiling. in people with Fetal Growth Retardation, run by Weill Medical College of Cornell University at 1 site in United States.

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 2 inclusion and 1 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: stopped early, as of the sponsor's last update on 3 Aug 2023. 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 United States. 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 was stopped early (reason given: Lack of personnel and funding resources). Results are not available in the source record.

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?

Occurrence of chromosomal anomalies as detected via fetal genome analysis of trophoblast cells (time frame: 6 weeks post pregnancy). 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 3 Aug 2023.
