New antibody aims to tame lupus by targeting troublemaking cells
NCT ID NCT07491900
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tests a new drug called HB2198 in 30 adults with moderate to severe lupus, including kidney inflammation. The drug is designed to temporarily remove certain immune cells (B cells) that drive the disease. Participants receive two doses and are monitored for a year to check safety and whether lupus activity improves.
