Study for the Evaluation of "MitoScore" Marker in the Diagnosis of Embryo

Status Active, not recruiting

Clinical Trial Summary

The number of copies of mitochondrial genes (mtDNA or "MitoScore") is related to the energy supply of the embryo, which can affect its ability to implant in the maternal uterus.

The objective of this study is to analyse the potential of MitoScore before embryo transfer as a marker to identify and select the embryo with greater capacity of implantation. First of all, chromosomally normal embryos will be selected and mtDNA copies will be quantified. Finally, embryos with less copies of mtDNA will be considered for embryo transfer.

Clinical Trial Description

The number of mitochondrial DNA copies (mtDNA) of a chromosomally normal embryo is related to a state of energy, which affects the ability of the embryo to implant in the maternal uterus. There is a decrease in the rate of implantation in euploid embryos containing a high number of mtDNA copies. It is known that after a certain number of mtDNA copies implantation is disrupted even in euploid embryos.

The main purpose of this study is to evaluate the possible relationship between the mtDNA content contained in developing embryos and the result of implantation in order to evaluate the potential of such relationship as a diagnostic tool.

The number of mtDNA copies present in chromosomally normal embryos will be quantified. Subsequently, the transfer of euploid embryos after the randomization will be using either routine morphological or MitoScore criteria.

Study population: women undergoing either IVF or egg donation that go through preimplantation genetic screening (PGS) for different indications, either in day 5/6 or day 3.

This is a triple blinded, randomized, prospective, clinical study where patients with embryos analyzed by PGS in blastocyst stage or day 3 and mitochondrial analysis with day 5/6 transfer, with deferred cycle for those analyzed in day 5/6 and fresh embryo transfer for those analyzed in day 3, will be randomized into two groups:

GROUP A: Embryo selection for transfer will be based initially on chromosomal normality and secondly on embryo morphology criteria (specific for IVF lab).

GROUP B: Embryo selection for transfer will be based initially on chromosomal normality and secondly on the MitoScore value, trying to transfer normal embryos containing the lowest number of mitochondrial DNA copies. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
