Study Summary

The overall objective is to evaluate the safety and efficacy of teprotumumab in the treatment of thyroid eye disease (TED) in participants who participated in the lead-in study HZNP-TEP-301 (NCT03298867; OPTIC) and who were either proptosis non-responders at Week 24 of HZNP-TEP-301 or were proptosis responders at Week 24 but met the criteria for re-treatment due to relapse during the Follow-Up Period of HZNP-TEP-301.

Primary Outcome

Proptosis responders were defined as participants with a ≥ 2 mm reduction from study baseline in proptosis in the study eye, without deterioration (≥ 2 mm increase) of proptosis in the fellow eye at Week 24. Participants missing Week 24 values were considered non-responders, aside from those with missing data related to the COVID-19 pandemic.
