Batoclimab shows promise for thyroid eye disease in extension study
NCT ID NCT05517447
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is for people who finished earlier trials of batoclimab for thyroid eye disease. It has two parts: one watches how long benefits last without treatment, and the other gives batoclimab to see if it helps more patients. The goal is to see if the drug can control eye bulging and other symptoms.
