Understanding Thymoglobulin use in stem cell transplantation

Thymoglobulin® Pharmacokinetics for Graft-versus Host Disease in Children and Adults Undergoing Hematopoietic Stem Cell Transplantation

Phase 4 Interventional Hospices Civils de Lyon · NCT05743400

This study is testing how well Thymoglobulin works to prevent graft-versus-host disease in patients getting stem cell transplants and aims to find the best dose for each person.

What this trial studies

This study investigates the pharmacokinetics of Thymoglobulin, a medication used to prevent graft-versus-host disease (GvHD) in patients undergoing hematopoietic stem cell transplantation (HSCT). The research aims to identify the relationships between drug exposure and response, which can vary significantly among patients. By analyzing these pharmacokinetic and pharmacodynamic parameters, the study seeks to optimize Thymoglobulin dosing to enhance clinical outcomes and minimize adverse effects. Participants will receive Thymoglobulin injections and undergo blood tests to monitor drug levels and effects.

Who should consider this trial

Good fit: Ideal candidates include patients aged 2 years and older receiving Thymoglobulin therapy as part of their first HSCT.

Not a fit: Patients who have received serotherapy within the last three months or have uncontrolled infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized Thymoglobulin dosing, improving patient outcomes in HSCT.

How similar studies have performed: Other studies have shown varying success with pharmacokinetic approaches in similar contexts, but this specific investigation into Thymoglobulin is relatively novel.
