About this study

Official title: A Comparison Between Home-made Vitrification & Thawing Media and a Commercially Available Brand on Blastocyst Survival, Expansion and Implantation

This study was conducted to evaluate and compare cryo-survival, re-expansion, and implantation rates of Day 5/6 human blastocysts that were vitrified with home-made media (HM) according to (Shady grove protocol) and warmed with gradual Thawing HM according to (Kuwayama protocol)with Global Fast Freeze/Thaw Kits (LifeGlobal, Canada).

Read the detailed description

Group 1 blastocysts were vitrified with the Vit HM according to shady grove protocol using open system on cryotopvit. device and thawed with gradual thawing technique using HM according to Kuwayama protocol. Group 2 blastocysts were cryopreserved with the Global Fast Freeze Kitusing open system on cryotopvit. device and thawed using Gobal fast thaw kit. Blastocysts were subsequently cultured for 6-8 h, assessed for survival and expansion, then transferred and the percentages of Positive hCG, clinical pregnancy, implantation, multiple pregnancy and abortion were recorded.

What participants receive

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

  • home made vitrification & thawing kitBiological

    home made vitrification was made and prepared for vitrification of blastocysts then thawing with a prepared thawed media too

  • commercially made vitrification & thawing kitBiological

    commercially available vitrification \& thawing kit were made and prepared for vitrification of blastocysts then thawing with a prepared thawed media too

What is being measured

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

  1. blastocyst immediate survival

    The effect of Vitrification protocol on the blastocyst immediate survival

    Measured: 0 hour at time of thawing

Secondary outcomes (3)
  1. pregnancy rate

    clinical pregnancy rate in these cases

    Measured: 2 weeks after transfer

  2. live birth rate

    live birth rate of positive pregnancy cases

    Measured: 9 months

  3. Blastocyst survival at 6 hours

    The effect of Vitrification protocol on the blastocyst survival after 6 hours

    Measured: 6 hours after thawing

Model description
Group 1 blastocysts were vitrified with the Vit (home made) HM according to shady grove protocol using open system on cryotop vit. device and thawed with gradual thawing technique using HM thawing media according to Kuwayama protocol. Group 2 blastocysts were cryopreserved with the Global Fast Freeze Kit using open system on cryotop vit. device and thawed using Global fast thaw kit. Blastocysts were assessed immediately for survival, subsequently cultured for 6-8 h, assessed for survival and expansion, then transferred and the percentages of Positive hCG, clinical pregnancy, implantation, multiple pregnancy and abortion were recorded.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing home made vitrification & thawing kit and commercially made vitrification & thawing kit in people with Blastocyst Disintegration, run by Benha University.

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 3 inclusion and 3 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 7 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

blastocyst immediate survival (time frame: 0 hour at time of thawing). 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 7 Sep 2018.
