Extension Study to Assess Batoclimab in Participants With Thyroid Eye Disease

Phase 3

Recruiting

• Conditions: Thyroid Eye Disease
• Interventions: Other: Observational cohort study; Drug: Batoclimab

• Registration Number: NCT05517447
• Lead Sponsor: Immunovant Sciences GmbH

Brief Summary

This is a 2-cohort (observational and treatment cohort) extension study for participants completing feeder studies (IMVT-1401-3201 or IMVT-1401-3202). The observational cohort will assess the durability of proptosis response of feeder studies off treatment. The treatment cohort will evaluate the efficacy of batoclimab as assessed by proptosis responder rate.
