NCT ID NCT05939037
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests whether the drug zanubrutinib, combined with standard rituximab, can improve nerve damage and disability in people with a rare blood condition called IgM MGUS. The study includes 35 adults across two Dutch hospitals. Participants take zanubrutinib daily for at least 6 months, and those who respond well may continue longer. The main goal is to see if walking, arm use, and overall function get better, while also checking for side effects.
