About this study

Official title: Evaluation of the Impact of Vitrification on the Reproductive Performance and Potential of Human Oocytes

The purpose of this study is to determine the rate of cryosurvival of mature oocytes following vitrification, and to then compare the reproductive potential of vitrified oocytes relative to those which have not been cryopreserved.

Read the detailed description

This study will recruit patients from the NY/NJ/CT/eastern PA area only.

Cryopreservation of human oocytes has a great potential to preserve or extend fertility in the face of disease whose treatment would result in a loss of ovarian function. (malignancy, severe autoimmune disease, etc.). It would also provide a means of quarantining oocytes to be used in oocyte donation to provide the lowest possible risk of infection.

There are two methods for storage of oocytes: slow freezing or vitrification. Slow freezing is the conventional method and has been successfully used for embryos since 1983 and more recently for oocytes. Recent reports indicate that vitrification may be more successful than slow freezing. However, the technique has not been rigorously validated to date. The aim of this study is to determine the rate of cryosurvival of mature oocytes following vitrification, and to then compare the reproductive potential of vitrified oocytes relative to those which have not been cryopreserved.

Patients will undergo ovarian stimulation for in vitro fertilization (IVF) according to the protocol recommended by their primary doctor. After retrieval, mature oocytes will be divided in half. One half will undergo vitrification, immediate thaw and intracytoplasmic sperm injection (ICSI). The other half will undergo just ICSI. All embryos will then develop on identical culture until day 3 or day 5. Prior to transfer, the best embryo from each group will undergo biopsy for genetic fingerprinting. The patient will have a 2 embryo transfer (one from each group). All extra embryos will be biopsied for pre-implantation genetic diagnosis (PGD) prior to being cryopreserved. If the patient becomes pregnant, we will follow up with an additional blood draw at approximately 9 weeks gestation and buccal swabs after the delivery of the infant(s).

What participants receive

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

  • Vitrification and PGDProcedure or surgery

    Also called Vitrification, PGD

    Half of the oocytes retrieved from each patient will undergo vitrification, immediate thaw and insemination. All embryos will undergo biopsy for PGD prior to transfer.

Study groups in NCT01223118
Study groupRoleWhat they receive
Oocyte VitrificationExperimentalEach patient will have oocytes randomized into two groups immediately after retrieval. Half of oocytes will be vitrified, thawed and inseminated. The other half will be inseminated only. All embryos will be biopsied for PGD prior to transfer and one embryo from each group will be transferred (vitrification and control groups). Following delivery, buccal swabs will be collected on all infants.
Receives: Procedure: Vitrification and PGD

What is being measured

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

  1. Aneuploidy Rate (evaluation of whether embryo is chromosomally normal)

    Compare the rate of chromosomally-abnormal embryos among embryos originating from vitrified oocytes versus embryos originating from fresh/control oocytes.

    Measured: 1 year

Secondary outcomes (2)
  1. Delivery rates

    All embryos will be biopsied prior to transfer and DNA samples will be collected from all infants. Compare embryonic and infant DNA to evaluate whether the live birth resulted from a vitrified or a fresh/control oocyte.

    Measured: 1 year

  2. Paired Sustained Implantation Rate (number of viable fetuses beyond the first trimester per embryo transferred)

    Among patients with a paired two blastocyst transfer, compare the implantation rate of embryos originating from vitrified oocytes versus embryos originating from fresh/control oocytes.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Vitrification and PGD in people with Fertilization, run by Reproductive Medicine Associates of New Jersey at 2 sites 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 6 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 23 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 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?

Aneuploidy Rate (evaluation of whether embryo is chromosomally normal) (time frame: 1 year). 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 23 Jan 2013.
