NCT ID NCT07416201

First seen Feb 19, 2026 · Last updated May 13, 2026 · Updated 14 times

Summary

This study follows 700 people with Down syndrome (and some healthy relatives) for up to 15 years to understand how their immune system changes over time. Researchers will look at infections, autoimmune problems, and blood cancers, and compare those who had part of their thymus removed during heart surgery to those who did not. The goal is to gather information, not to test a new treatment.
