Massive study to uncover hidden link between blood mutations and immune disorders
NCT ID NCT05969821
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will follow 5,000 adults with immune system problems to see if certain blood cell mutations (called clonal hematopoiesis) are linked to their condition. Researchers will track new cases of immune-related diseases over time. No treatments or drugs are tested—this is purely an observation study to gather information.
