Multi-omic profiling of children and adults receiving bone marrow transplant or CAR‑T therapy

Multi-omic Characterization of Pediatric and Adult Patients Undergoing Hematopoietic Stem Cell Transplantation and Advanced Cell Therapies

Not applicable Interventional IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT07464483

This project will test whether analyzing the gut microbiome and other biological samples before and after bone marrow transplant or CAR‑T therapy in children and adults can help predict complications and recovery.

What this trial studies

This single‑center effort will collect stool, urine, serum, saliva, and available biopsy specimens from pediatric and adult patients undergoing allogeneic hematopoietic stem cell transplantation or CAR‑T infusion. Samples will be analyzed using multi‑omic approaches (microbiome sequencing, metabolomics, host immune profiling, and histology) at multiple time points before and after therapy. Researchers will correlate molecular signatures with clinical outcomes such as graft‑versus‑host disease, infections, relapse, immune reconstitution, and treatment‑related toxicities. The goal is to identify biomarkers that could inform personalized prevention and management strategies.

Who should consider this trial

Good fit: Ideal candidates are pediatric or adult patients scheduled to receive allogeneic hematopoietic stem cell transplantation or CAR‑T infusion who can provide informed consent and biological samples.

Not a fit: Patients not undergoing allogeneic HCT or CAR‑T, those unwilling to provide serial biological samples, or those unable to attend follow‑up visits are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help identify biomarkers to predict and prevent complications like graft‑versus‑host disease, severe infections, and delayed immune recovery.

How similar studies have performed: Previous adult studies have linked reduced gut microbial diversity and pathogen domination with worse post‑transplant outcomes, but comprehensive pediatric‑to‑adult multi‑omic characterization across HCT and CAR‑T is relatively novel.
