Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 50 years
  • Women only
  • Healthy volunteers accepted
  • Adult

Study population: Women of reproductive age who, in order to achieve a pregnancy, will have embryos created from thawed autologously or heterologously implanted oocytes that were either: * cryopreserved at the time of or following the Registry's launch, or * cryopreserved prior to the Registry's launch, but will undergo thaw/fertilization/transfer procedures while the subject is enrolled in the Registry.

Who may be able to join

  • Must be in an ART program
  • Donor and recipients must be of reproductive age (18-50 years old, inclusive at the time of oocyte freezing and/or thawing) who intend to achieve a pregnancy by utilizing frozen thawed autologous or heterologous oocytes
  • Female and partner (if applicable) must voluntarily provide written informed consent/HIPAA authorization prior to any Registry-related data collection
  • Female and partner (if applicable) must be willing to provide a second written informed consent following each live birth prior to any Registry- related data collection on birth characteristics and twelve (12) month evaluation of offspring
  • Children born from women who take part in this registry from birth to 12 months (+/- 1 month) of age

Who cannot join

  • Have clinically significant systemic disease
  • Have abnormal, undiagnosed gynecological bleeding
  • Have any contraindication to Controlled Ovarian Stimulation (COS) for ART and to gonadotropins to be used in ART
  • Also, in a rare situation, are undergoing ET with mixed embryos generated from fresh oocytes produced in the current cycle as well as frozen embryos generated from nonfrozen oocytes obtained in a previous ART cycle
  • Children born from women who do not take part in this Registry
  • Any offspring of woman who are not Registry subjects cannot take part in this registry

About this study

Official title: A Phase IV, Prospective, Multicenter, Observational Oocyte Cryopreservation Registry

Phase IV, prospective multicenter, observational Registry will track cycle outcomes for subjects who are thawing frozen oocytes for subsequent use through in vitro fertilization (IVF) and embryo transfer (ET)

Read the detailed description

Subjects will be enrolled at as many ART clinics that offer oocyte cryopreservation and are willing to participate in the Registry. Oocytes will be retrieved and cryopreserved from autologous or heterologous donors. When the subject decides she would like to get pregnant, oocytes will be thawed, fertilized and the resultant embryos will be transferred to the oocyte donor (for autologous use) or to another recipient (for heterologous use). The treatment regimen will be completed with births and well-baby follow-up of children at 12 months of age. Information on children will be submitted by their parents to the Investigators. Data collection for the Registry will be active for a maximum of five (5) years, including three (3) years of enrollment and two (2) additional years to complete the well-baby follow-up for all the children.

What is being measured

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

  1. Thawing Cycle Level Live Birth Rate

    Live birth rate per thawing cycle was calculated from the number of live births divided by the number of oocytes thawed less the number of embryos cryopreserved from thawed oocytes, averaged over all thawing cycles.

    Measured: Birth of one or more live babies

Secondary outcomes (8)
  1. Oocyte Level Live Birth Rate

    Oocyte Level Live Birth Rate was calculated from the total number of live births divided by the total number of oocytes thawed less the total number of embryos cryopreserved from thawed oocytes

    Measured: Birth of one or more live babies

  2. Number of Live Babies

    Measured: Birth of one or more live babies

  3. Number of Oocytes Frozen

    Measured: At cryopreservation

  4. Number of Oocytes Thawed

    Measured: At start of thawing cycle

  5. Oocyte Survival Rate

    Number of oocytes fertilized divided by number of oocytes thawed per thawing cycle

    Measured: At time of fertilization

  6. Implantation Rate

    Implantation rate was calculated as the number of fetal sacs per transferred embryo averaged over all thawing cycles

    Measured: At time of ultrasound after embryo transfer

  7. Number of Clinical Pregnancies

    Number of clinical pregnancies defined as the presence of one or more fetal sacs with a heartbeat.

    Measured: At time of ultrasound after embryo transfer

  8. Number of Miscarriages

    Number of pregnancy outcomes reported as spontaneous abortions

    Measured: Anytime after embryo transfer

Questions about this trial

What is this clinical trial studying?

An observational study of Oocyte Cryopreservation, run by EMD Serono at 15 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 5 inclusion and 6 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 24 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 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?

Yes. Results are posted in the registry (first posted 24 Jan 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Thawing Cycle Level Live Birth Rate (time frame: Birth of one or more live babies). 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 NCT00699400, which also lists 1 linked publication.

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 24 Jan 2014.
