Active clinical trials for "Aneuploidy"

Analysis of embryonic cell-free DNA (cfDNA) present in the spent culture media (SCM) is a non-invasive alternative for preimplantation genetic testing for aneuploidies (PGT-A) that avoids the technical challenges and limitations of biopsy. Initial studies investigating this non-invasive PGT-A (niPGT-A) method reported variable concordance between cfDNA in SCM and the trophectoderm sample (~ 30%-86%) and indicated a contribution from both the inner cell mass and trophectoderm to the cfDNA in SCM. This study aims to evaluate the use of the embryo culture medium as a source of genetic material for PGT-A and validate a niPGT-A protocol using cfDNA in SCM.

The study is promoted by the Emilia Romagna Region which identified in the Bologna AUSL the coordinating center (Unità Operativa Complessa Laboratorio Unico Metropolitano, LUM, Maggiore Hospital). The medical genetics centers, participating in the technical-scientific coordination group of assessment (resolution No. 1894, 4/11/2019), the family counseling centers and the region prenatal hospital clinics are involved as collaborative experimental centers. Currently, 14,400 combined tests are carried out in the Emilia Romagna Region every year. As a result offering the new non-invasive NIPT test, it is estimated that the number of participants in the screening program will increase by up to 20,000/year. The study will collect data on the women who will access the combined test in the first 9 months of the protocol and join the enrollment.

The purpose of this study is to develop and evaluate a blood test and automated microfluidic test platform for the prenatal screening of fetal aneuploidy.

The objective will focus on the characterization of DNA fragments present in Blastocoele fluid, and the evaluation of these fragments as potential target for Preimplantation Genetic Diagnosis. To reach this goal, real-time PCR, Whole Genome Amplification techniques and -subsequently- Next Generation Sequencing and aCGH approaches will be used.

The study is conducted to evaluate the sensitivity and specificity of non-invasive preimplantation genetic testing for aneuploidy (NiPGT-A) using cell free DNA into spent culture medium (SCM).
