New antibody treatment offers hope for rare blistering skin disease
NCT ID NCT06900010
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug called CM336 in 30 adults with moderate to severe autoimmune bullous disease, a condition where the immune system attacks the skin causing painful blisters. The drug targets specific immune cells to reduce this attack. The main goal is to see if the drug can help patients achieve lasting remission.
