Infliximab Efficacy, TDM and Serum TNFα Levels in Pediatric HSCT Recipients With aGVHD: Prospective Observational Study
Italy28 participantsStarted 2022-04-01
Plain-language summary
In children receiving a hematopoietic stem cell transplant (HSCT), blood levels of TNFalpha (an inflammatory cytokine) at the onset of the acute GVHD (graft-versus-host disease) could be correlated with the severity of the disease. The hypothesis is that the highest infliximab (a biologic drug against TNFalpha) could be associated with a significant reduction in TNFa levels and, subsequently, with a faster remission of the symptoms and prevention of disease progression. Moreover, a rapid drop of infliximab serum concentration, documented by therapeutic drug monitoring (TDM), could be related to the active phase of GVHD and higher production of TNFalpha. Therefore, the study is aimed at investigating whether the drop in infliximab plasma concentrations could be associated with clinical response and production of TNFalpha.
HSCT children receiving infliximab to control GVHD are enrolled. Blood samples will be collected during treatment and they serve to measure drug and TNFalpha concentrations. Drug levels are analyzed by a population pharmacokinetic modeling and results are compared with plasma concentrations of TNFalfa and clinical response.

* At least five days of steroid treatment (minimum 1 mg/kg of methylprednisone or equivalent) for systemic aGVHD without clinical or laboratory signs of response or no steroid treatment for onset of grade I-II hepatic/gastroesophageal/intestinal isolated aGVHD;
* Patients who consent for the off-label use of infliximab and data processing for research purposes based on the institutional model GECO;
* At least one dose of infliximab received during aGVHD management;
* Minimum follow-up after infliximab administration: 6 months
Exclusion Criteria:
* Follow up \< 6 months.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
