5 Clinical Trials for Various Conditions
The purpose of this study is to determine if 24 chromosome preimplantation genetic diagnosis (PGD) increases implantation and delivery rates in couples attempting to conceive through in vitro fertilization (IVF).
Gene Security Network has developed a novel technology called Parental SupportTM (PS) which is used for Preimplantation Genetic Screening/Diagnosis (PGS/D) during in vitro fertilization (IVF). This technology allows IVF physicians to identify embryos, prior to transfer to the uterus, which have the best chance of developing into healthy children. The purpose of this study is to validate clinical use of PS to detect specific genetic mutation(s) known to cause severe inheritable diseases in embryos produced by at-risk couples. This may be done while simultaneously testing these embryos for aneuploidy. This study will allow for first of its kind commercial PGS/D testing to detect disease-associated genetic mutations together with aneuploidy screening.
Natera is recruiting patients for a research study evaluating pregnancy and implantation rates in women undergoing In Vitro Fertilization (IVF) and Preimplantation Genetic Screening (PGS). PGS is also referred to as Preimplantation Genetic Diagnosis (PGD) for aneuploidy. Healthy women undergoing IVF who are between the ages of 35 to 42 years are being recruited to participate in a randomized study. The purpose of this study is to determine whether PGS- testing of embryos created during IVF for chromosomal abnormalities, prior to transfer to the uterus- improves pregnancy and implantation rates in patients when compared to patients whose embryos are not tested. PGS will be conducted using 24 Chromosome Aneuploidy Screening with Parental Support from Natera. All subjects who qualify and enroll will receive discounted IVF medications (both TEST and CONTROL arms). If you become pregnant during the study, you will receive a small payment for providing information about your pregnancy and birth. If you are assigned to the TEST arm of the study you will receive free PGS.
Patients who have shown previous implantation failures, despite transferring good quality and chromosomally normal embryos (diagnosed by PGT-A), could have a displaced Window of Implantation (WOI) and consequently, alterations in their endometrial receptivity. The correction of this displacement can improve the results of the Assisted Reproduction Treatments (ART). The ERA test (Endometrial Receptivity Analysis) evaluates the transcriptomic endometrial profile to determine if the patient's uterus is receptive when the embryo is transferred during an In Vitro Fertilization (IVF) process, and identifies the personalized WOI of the patient. This process is called Personalized Embryo Transfer (pET). The Preimplantation Genetic Test of Aneuploidies or PGT-A (Preimplantation Genetic Testing for Aneuploidy), is currently carried out using Next Generation Sequencing (NGS) and serves to identify chromosomally normal embryos prior to their transfer in an IVF treatment. Aneuploidies are rarely compatible with life or can cause congenital diseases. So, the identification of chromosomally normal embryos, improves the success of reproduction in cases in which infertility is caused by such aneuploidies. Therefore, the aim of this study is to determine, in a randomized and prospective way, the clinical benefit of adding the ERA test to the embryonic aneuploidies test for patients with a PGT-A indication.
The objective of this study is to demonstrate that Preimplantation Genetic diagnosis will significantly reduce spontaneous abortions and increase ongoing pregnancy rates in patients of advanced maternal age (37-42) undergoing IVF. We would like to test this hypothesis by a randomized trial performed with the most suitable conditions using very successful IVF laboratories capable to perform the embryo biopsy under strict controlled conditions after proper training and validation of the techniques.
