Primary Sjögren's Syndrome

This is a Phase 2b, multicenter, randomized, double-blinded, placebo-controlled study to assess the efficacy and safety of IMVT-1402 in adult participants with moderate to severe systemic primary Sjogren's disease (SjD).

Primary Sjögren's syndrome (pSS) can affect various organs, sometimes leads to life-threatening conditions and is always responsible for a decreased quality of life. Its evolution is chronic, with flares and relapses, and the need for reliable biomarkers to be carried out routinely is major in patients' follow-up. Because of the existence of autoreactive immunoglobulins E (IgE) in autoimmune diseases, the recently described role for anti-Ro/SSA antibodies in inducing interferon alpha (IFNα) signaling and the specific pharmacologic properties of IgE, anti-Ro/SSA IgE should be an interesting biomarker to determine pSS's activity. The aim of the study is to evaluate whether the proportion of anti-Ro/SSA IgE positive patients is higher in patients with active disease (i.e. Eular Sjögren Syndrome Disease Activity Index≥ 5). All consecutive patients with pSS (new or already known diagnosis) will be included, Anti-Ro/SSA IgE titers will be determined, the disease's features will be collected (including Eular Sjögren Syndrome Disease Activity Index/Eular Sjogren's Syndrome Patient Reported Index).

A multi-center, prospective, open-label, randomized controlled study of efficacy and safety of Iguratimod in patients with Primary Sjögren's syndrome

The ASSESS national multi-center prospective cohort (Assessment of Systemic complications (Signs) and Evolution in Sjögren's Syndrome "SS") was set up in 2006 thanks to a grant of the French Ministry of Health. Fifteen centers for autoimmune diseases consecutively included consecutive patients with Primary Sjögren's Syndrome "pSS" fulfilling American-European Consensus Criteria (AECG) between 2006 and 2009. The study was approved by the Ethics Committee of Bichat Hospital in 2006. All patients gave their informed written consent. This study was followed for 5 years with the grant of the French Ministry of Health and this study will be extended for 20 years by French Society of Rheumatology (SFR). On an annual basis for a duration of 20 years, a thorough standardized paper case report form (CRF) was filled prospectively by clinicians.
