Could a cell infusion free organ transplant patients from lifelong drugs?
NCT ID NCT06997471
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests whether giving a special mix of blood cells after an organ transplant can help the body accept the new organ without needing lifelong anti-rejection drugs. About 10 children and adults receiving kidney, lung, or intestinal transplants will get the cell infusion after a short preparation. The main goal is to see if the approach is safe and can reduce rejection and infections.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Pediatric patients (\<18 years old) who are candidates to receive intestinal or lung transplantation (before SOT). * Pediatric (\<18 years old) or adult patients (≥18 years old) who are either candidates for renal transplantation or have already undergone renal transplantation and remain candidates for subsequent HSCT. * Patients who provide informed consent (or their legal guardians in the case of minors) before any study-related procedures. * Recipients should have no active infectious disease or other medical condition that would contraindicate the combined transplantation procedure, as determined by the investigational team. Exclusion Criteria: * Recipients with existing bone marrow disorders or those receiving medications known to adversely affect bone marrow function. * Patients with advanced organ dysfunction (hepatic, cardiac, or pulmonary) incompatible with successful combined transplantation. * Patients with active or uncontrolled autoimmune conditions that may interfere with transplantation and the induction of chimerism. * Patients with known allergies to medications or products required for conditioning or transplantation. * Patients with severe psychiatric or cognitive disorders that may interfere with adherence to study instructions or postoperative care. * Patients currently enrolled in another clinical trial that could interfere with the outcomes or safety of this study. * Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test. * Any other condition that, in the opinion if the Investigator, may interfere with the efficacy and/or safety evaluation of the trial.
