Studying how drugs transfer through the placenta

Ex Vivo Study of Drugs Transfer Across the Placenta

Observational Assistance Publique - Hôpitaux de Paris · NCT04400084

What this trial studies

This observational study aims to investigate the transfer of drugs across the placenta using human cotyledon perfusion after delivery. Pregnant women are often excluded from clinical trials, leading to a lack of data on drug safety and efficacy during pregnancy. By perfusing the maternal and fetal sides of the placenta with a drug and a control molecule, researchers will analyze the concentrations of these substances to understand the mechanisms and quantities of drug transfer. The study will also explore factors that may influence drug transfer, such as genetics and protein expression.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women over 18 years old, from the 24th week of amenorrhea, who have provided informed consent.

Not a fit: Patients with pre-existing maternal pathologies or pregnancy complications, such as diabetes or pre-eclampsia, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide crucial insights into the safety and efficacy of medications used during pregnancy, ultimately improving maternal and fetal health outcomes.

How similar studies have performed: While studies on drug transfer across the placenta exist, this specific approach using cotyledon perfusion is relatively novel and may provide new insights.
