Filter by:This is a phase2a, multicenter, double-blind, placebo control, randomized study to investigate the efficacy and safety of SA001 in subjects with pSS. A total of 28 subjects (including dropout rate of 30%) will be randomized in a 1:1:1:1 ratio to receive 3 different doses of SA001 or placebo everyday for 8 weeks. Screening visit will be performed within 1 to 2 weeks(run-in period) prior to dosing after signing the informed consent form (ICF). During the run-in period, if necessary, subjects will apply artificial tears in the symptomatic eyes according to the dosage of artificial tears. Only subjects who have completed the run-in period and who are determined to be suitable for the study eligibility(inclusion/exclusion) criteria as a result of the screening evaluations are randomized to one of the four groups. Subjects will receive investigational product start on Day 0 for 8 weeks during the active treatment period. Subjects will visit to the study site on 4 and 8 weeks after starting dosing investigational product. Subjects will be in this study approximately 12weeks, which includes run-in period of 1 to 2weeks and a safety follow-up period of 2weeks.
There are no approved treatments for pSS and the clinical endpoints currently used in clinical trials are inadequate to capture all aspects of the disease that should be evaluated in clinical trials. The newly developed composite endpoint: Sjögren's Tool for Assessing Response to treatment (STAR) will allow a more specific and meaningful assessment of treatment efficacy in pSS. Because of the heterogeneity of the disease and of the central role of the interplay between B- and T-cells in the pathogenesis, it is worth to evaluate combination of conventional synthetic immunomodulatory drugs targeting both B- and T-cells.
This study aims to evaluate the diagnosis performance of several item used for the classification, the diagnosis and the prognostic of pSS (primary Sjogren syndrome)
Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease characterized by lymphocytic infiltration leading to destruction of acinar and ductal cells and loss of glandular parenchyma. The main symptoms of pSS are dry eyes and dry mouth, diffuse pain, and fatigue. One third of patients develop systemic features, the most severe being lymphomas. Serum IL-6 is increased in serum, saliva, and tears of patients with pSS. IL-6 plays a pivotal role in B-cell activation, a hallmark of the pathogenesis of pSS, and in T-cell differentiation. Tocilizumab, a recombinant humanised monoclonal antibody acts as an IL-6R antagonist. The aim of this randomised double blind placebo controlled trial iss to evaluate the efficacy of tocilizumab for the treatment of pSS.
