Using virus-specific T-cells to treat CMV infections in young patients
Official title: A Pilot Study in the Treatment of Refractory Cytomegalovirus (CMV) Infections With Related Donor CMV Specific Cytotoxic T-cells (CTLs) in Children, Adolescents and Adult Recipients
Run by New York Medical College · NCT03266640 · Data updated 2026-11-12
This study is testing a new treatment using special immune cells to help children and young adults with stubborn CMV infections after organ transplants when regular medicines haven’t worked.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are children, adolescents, and young adults with refractory CMV infections post-transplant who have not responded to antiviral therapies.
✕Probably not a fit
Patients who do not have refractory CMV infections or those who are not post-transplant may not receive any benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This clinical trial aims to administer cytotoxic T-lymphocytes (CTLs) specifically targeting cytomegalovirus (CMV) to children, adolescents, and young adults suffering from refractory CMV infections following allogeneic hematopoietic stem cell transplantation or solid organ transplantation. The CTLs are manufactured using the Miltenyi CliniMACS Prodigy Cytokine Capture System and are intended for patients who have not responded to standard antiviral therapies. The study will evaluate the safety and efficacy of this innovative treatment approach in a vulnerable patient population with primary immune deficiencies.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with refractory CMV infections, potentially improving their health outcomes and quality of life.
How similar studies have gone: Other studies have shown promise in using virus-specific T-cells for treating viral infections, suggesting that this approach may be effective.
