Mayo clinic launches gut bacteria study for rare plasma cell disorders
NCT ID NCT06252948
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at the gut microbiome (the bacteria living in the digestive system) of people with POEMS syndrome, multiple myeloma, MGUS, AL amyloidosis, and healthy household members. Participants provide stool samples at home using a collection kit. The goal is to understand how gut bacteria differ in these conditions. No treatment is given; this is an observational study.
