Filter by: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).
A randomized, double-blind, placebo controlled, 2-arm multicenter phase 3 study to assess the efficacy and safety of ianalumab in patients with active Sjogren's syndrome (NEPTUNUS-1)
This study aims at elucidating the mechanism of action of ianalumab in salivary glands and explore relationships with clinical assessments
The investigators had observed that baricitinib was effective and safe in active pSS patients in a pilot study. So the investigators plan to conduct a multi-center, prospective, open-label, randomized study to compare the efficacy of baricitinib + hydroxychloroquine (HCQ) with HCQ alone in active pSS patients. The participants will be randomized (1:2) to receive HCQ (200mg twice a day) or baricitinib (4mg per day) + HCQ (200mg twice a day) until week 24. The primary endpoint is the ESSDAI and ESSPRI response (define as an improvement of ESSDAI at least three points, and ESSPRI at least one point or 15%) at 12 weeks. According to an expected response rate of 70% in baricitinib + HCQ group and 30% in HCQ group, the investigators will involve approximately 87 participants (29:58) with 20% drop out rate. The investigators will switch HCQ to baricitinib + HCQ if the participants has no response at 12 weeks. The investigators hypothesized that baricitinib was effective and safe in active pSS patients.
N-acetylcysteine (NAC) allows the elimination of reactive oxygen species (ROSs) and it has an anti-inflammatory effect. For this reason, NAC has been used and researched for treatment of several diseases, such as autoimmune diseases. In these diseases there are a process of oxidative stress due to chronic inflammation, which promotes an imbalance between ROSs levels and the cellular capacity to eliminate reactive intermediates and repair the resulting damage through antioxidants. The imbalance between the production of free radicals from oxygen and antioxidant species may also be involved in the pathogenesis of primary Sjögren's syndrome (pSS). In fact, increased levels of oxidative stress markers were detected in biopsy samples from minor salivary glands in these patients. Treatment of pSS is not well established and it is also not able to modify the evolution of the disease, being often only symptomatic. In addition, there is little data in the literature regarding the true efficacy of NAC in the treatment of pSS and the few existing studies have evaluated heterogeneous populations (including patients with other causes of sicca syndrome) and validated instruments to measure the symptom index and disease activity were not use in these previous studies. Thus, the present randomized double-blind clinical study aims to evaluate the efficacy of NAC in the control of sicca syndrome symptoms in a homogeneous population of patients with pSS (not only regarding the classification criteria, but also regarding the low rate of systemic disease activity at study inclusion) through tests widely accepted in the literature. Additionally, the investigators will study the possible role of NAC on oxidative stress in peripheral blood and saliva of these patients.
Sjögren syndrome (SS) in adults is characterised by inflammation of the exocrine glands, principally the salivary and lacrimal glands resulting in xerostomia (dry mouth) and xerophthalmia (dry eyes).It can also present with more extensive exocrinopathy as well as extra-glandular, systemic features. SS is defined as primary SS (pSS) when it occurs in isolation, and as secondary SS, if associated with other autoimmune conditions. The incidence and prevalence rates of SS vary depending on the population. To date, there have been no studies reporting accurate incidence or prevalence of SS in childhood. Childhood onset SS defined as disease diagnosed before 18 years of age is believed to be rare; however, it is likely it is under-recognised and therefore under-diagnosed. The overarching aim of this study is to identify epidemiological, clinical and laboratory characteristics of paediatric SS in a United Kingdom (UK) multi-centre cohort of patients. Using this data our goal is to develop universally accepted classification criteria that could be validated for use in a paediatric population. Inclusion criterion for the study and repository is a diagnosis of SS made before 18 years by the referring physician. A data collection pack will be sent to authors willing to participate. Information collected will include but not exclusive to: demographic, clinical and laboratory/histological data at diagnosis and subsequent follow-up appointments. Biological samples including blood, tears, saliva, urine and glandular and extra-glandular (e.g. renal) tissue will be collected prospectively if available. Outcome measures related to disease activity and damage, as well as patient reported outcomes will also be collected at set time points (every 6 months) and during flares. PaedSSCoRe will capture data on a significant cohort of children with SS providing a powerful resource to help improve our understanding of the pathogenesis and natural course of this disease. Prospective data collection will allow a fuller analysis of poor prognostic features, impact of therapy and damage accrual, and variable outcome of childhood SS.
This study investigates the feasibility of a fully remote effectiveness evaluation of a self-management smartphone application for those with Sjogren's syndrome.
This study will evaluate the safety and tolerability of iscalimab at two dose levels in patients with Sjögren's Syndrome, who participated in the TWINSS core study, CCFZ533B2201(NCT03905525). Additionally, this Extension study will further explore the pharmacokinetics (PK) and efficacy of iscalimab at two dose level.
The coronavirus disease 2019 (COVID-19) pandemic is a potentially fatal disease that represents a great global public health concern. In European countries such as Spain, Italy, Germany, Portugal, England and France, the pandemic has been of utmost importance. To date, no treatment has been robustly validated, and two theoretically opposite therapeutic strategies are proposed, based either on antiretroviral therapy or on immunomodulating agents. In this complex context, people living with immune-mediated inflammatory diseases (IMID) raise specific concerns due to their potentially increased risk of infections or of severe infections. Among IMID, Sjögren's syndrome, systemic lupus erythematosus, rheumatoid arthritis, spondyloarthritis and giant cell arteritis are some key diseases. In this cross-sectional, observational, multi-centric study, the investigators aim to assess both clinical and serological prevalence of COVID-19 among samples of IMID patients in Europe. In parallel, the investigators aim to compare the prevalence of COVID-19 seroconversion across these five IMIDs, their penetration across different 6 European countries (France, Italy, Spain, Germany, United Kingdom and Portugal), and to assess the severity of COVID-19 in these patients. Moreover, changes in treatment will be assessed, including immunomodulatory tapering or discontinuation, its causes over the outbreak period, as well as the incidence of IMID flares and their severity over this same period. Finally, patient's perceptions towards the pandemic will be evaluated and compared to medication beliefs. Data will be collected through questionnaires during medical visit or phone consultation and serological tests will be performed within routine blood collection. As so, all study procedures are comprised within usual care. Through this study the investigators expect to have a better knowledge of the clinical and serological prevalence of COVID-19 in IMID across Europe, along with the psychological, clinical, and therapeutic impact of COVID-19 in this particular patient population.
