Clinical Trial Summary

This study aims to evaluate the efficacy, safety and tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of efgartigimod PH20 SC in participants with active, moderate-to-severe TED, compared with placebo PH20 SC. After the screening period, eligible participants will be randomized in a 2:1 ratio to receive efgartigimod PH20 SC or placebo PH20 SC, respectively during the double-blinded treatment period (DBTP). At the end of the DBTP, participants may enter a follow-up observational period while off study drug. Some participants may also enter the open-label treatment period with efgartigimod PH20 SC. The study duration varies from approximately 60 to 110 weeks. An alternative list of clinical sites open for recruitment could be found in the other UplighTED study record (https://www.clinicaltrials.gov/study/NCT06307613)
