Preimplantation Genetic Screening in IVF Treatment — PGSINIVF  

Infertility Clinical Trial

Official title:
Preimplantation Genetic Testing for Aneuploidy (PGT-A) in in Vitro Fertilisation (IVF) Treatment: Pilot Phase of a Randomised Controlled Trial

Clinical Trial Summary

This is the pilot phase of a randomised controlled trial. The purpose of the pilot study is to assess the ability to recruit, randomise, adherence to the study protocol and plan for a full study. The purpose of the full study will be to determine if a policy of embryo selection and transfer based on morphological evaluation and preimplantation genetic testing for aneuploidy (PGT-A) is a more clinically effective, safer, cost-effective and acceptable way to provide in vitro fertilisation (IVF) treatment in women of advanced reproductive age compared to the routine practice of embryo selection and transfer based on morphological evaluation alone.

Clinical Trial Description

The target population for the trial are women aged 35 - 42 years undergoing IVF±ICSI treatment. Intervention The experimental strategy will be to perform PGT-A (also referred as preimplantation genetic screening - PGS) involving trophectoderm biopsy on embryos reaching the blastocyst stage on day 5/6/7 following egg collection. All embryos will be frozen after the biopsy procedure. Comprehensive chromosome screening (CCS) of all chromosomes will be performed using next generation sequencing (NGS). Embryos will be categorised as euploid, mosaic euploid and aneuploid embryos and embryos will be ranked based on the degree of euploidy. Only euploid embryos or mosaic euploid embryos deemed suitable to be replaced will be transferred in subsequent frozen-thawed embryo transfer cycles. Comparison Women in the control arm will have the fresh embryo transfer procedure on day 5 following egg collection or a frozen-thawed embryo transfer as first line if clinically indicated in keeping with current routine practice. Embryo selection for transfer will be based on morphological criteria alone. ;
