Primary Sjögren's Syndrome Clinical Trial
Official title:
Open-Label Extension Study to Evaluate the Safety of Efgartigimod in Adult Patients With Primary Sjögren's Syndrome (pSS) Who Complete Qualifying Efgartigimod pSS Studies
Efgartigimod contributes to successfully treat pSS and has the potential to improve disease manifestations by the reduction of IgG autoantibodies in pSS. This open-label extension study will evaluate the long-term safety of efgartigimod in participants with pSS who have completed the treatment period of the qualifying efgartigimod studies (including ARGX-113-2106).
ARGX-113-2211 is a long-term, single-arm, open-label, multicenter extension study of the pSS-qualifying efgartigimod studies designed to evaluate the long-term safety of efgartigimod in adult patients with pSS. Participants will be enrolled from both active and placebo arms of qualifying efgartigimod studies and receive efgartigimod 10 mg/kg over 48 weeks in the extension study without knowledge of their treatment assignment in the qualifying study. Eligible participants must have completed the treatment period of the qualifying study and must not have permanently discontinued the IMP in that study. ;
