Probably not a fit

Patients who have permanently discontinued batoclimab or require immediate surgical intervention may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This extension study involves two cohorts: an observational cohort that evaluates the durability of proptosis response after participants have completed feeder studies, and a treatment cohort that assesses the efficacy of batoclimab in improving proptosis rates. Participants must have completed a prior study and will be monitored for their response to treatment. The study aims to gather additional data on the long-term effects of batoclimab in patients with thyroid eye disease.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients suffering from thyroid eye disease.

How similar studies have gone: Other studies involving monoclonal antibodies for autoimmune disorders have shown promising results, suggesting potential success for this approach.
