Clinical Trial Summary

It has been proposed that enriching transfer media with hyaluronan (EmbryoGlue medium) improves pregnancy outcomes compared with media containing lower concentrations of this molecule. However, none of previous studies included preimplantation genetic testing for aneuploidy (PGT-A) embryos. In order to investigate the impact of this hyaluronan-enriched on pregnancy outcomes, it is essential to evaluate its efficacy on euploid-only embryo transfers. The aim of the present study is to evaluate whether a short period of exposure of euploid blastocysts to EmbryoGlue prior to and during transfer positively impact on pregnancy outcomes of frozen embryo transfer (FET) cycles.

Description:

The study period will be determined by the completion of the predetermined sample size, with two interim analyses planned when 35% (n=274) and 70% (n=548) of the target sample size is achieved to calculate conditional power. If conditional power is estimated to be lower than 15% at first interim analysis or lower than 30% in the second interim analysis, the trial will be stopped due to futility. The study will be performed in Abu Dhabi-Fertility clinic. During the period of this prospective study, euploid blastocysts of enough quality that have been biopsied only on Day-5 for PGT-A, will be warmed for single blastocyst transfer. The patient´s endometrial preparation protocol for FET will be restricted to HRT only. The study will be double-blinded (blinded to patient and doctor performing transfer).
