Supercharged donor cells take on viruses after transplant
NCT ID NCT02048332
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This study tests whether specially grown donor immune cells (viral-specific T-cells) can safely treat viral infections that often occur after a stem cell transplant. These infections can be serious and sometimes don't respond to standard antiviral drugs. The approach aims to boost the patient's weakened immune system using cells from their donor, potentially reducing hospital stays and side effects from medications.
