NCT07227116 · Shady Grove Fertility Reproductive Science Center
Evaluating the Status of Complex Aneuploidy to Locate Additional Transferrable Embryos
(ESCALATE)
What this study is about
This study aims to evaluate the reproductive potential of embryos classified as "complex aneuploid" (involving three or more abnormal chromosomes) or "chaotic" (six or more abnormal chromosomes) through preimplantation genetic testing for aneuploidy (PGT-A).
View original scientific description
This study aims to evaluate the reproductive potential of embryos classified as "complex aneuploid" (involving three or more abnormal chromosomes) or "chaotic" (six or more abnormal chromosomes) through preimplantation genetic testing for aneuploidy (PGT-A). Specifically, we seek to determine whether embryos initially reported as having multiple chromosomal abnormalities might still have the potential for normal chromosomal composition, the opportunity for transfer, and ultimately, the potential to achieve a live birth through re-biopsy and reanalysis. Key Information: This portion of the study seeks your consent for the re-biopsy and genetic reanalysis of the embryos only. It does not yet include consent for potential future transfer. Participation remains completely voluntary, and your decision will not affect your current or future care. We deeply appreciate your support and commitment to advancing fertility research.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
