E.3 | Principal inclusion criteria |
Adults (18 years or older) SchS diagnosis based on Strasbourg clinical criteria Active SchS, refractory to treatment with antihistamines, NSAIDS or colchicine, hydroxychloroquine or dapsone Patients who have a symptom score (PGA) of at least 8 (0-20) at baseline If necessary, concurrent/ongoing treatment with a stable dose of systemic corticosteroids not greater than 10mg/d for 14 days prior to screening If necessary, concurrent/ongoing treatment with a stable dose of antihistamines and NSAIDs for 7 days prior to screening Able to read, understand and willing to sign the informed consent form and abide with study procedures Willing, committed and able to return for all clinic visits and complete all study-related procedures, including willingness to have SC injections administered by a qualified person In females of childbearing potential: Negative pregnancy test within 28 days of randomization; males and females willing to use highly effective contraception (Pearl-Index < 1) during study treatment and for a minimum of 3 months after last dose of TCZ.

A woman will be considered not of childbearing potential if she is post-menopausal for greater than two years or surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy) Subjects are considered eligible, if they meet the following tuberculosis (TB) screening criteria: no history of latent or active TB prior to screening, no signs or symptoms suggestive of active TB, no recent close contacts with a person with active TB, and negative QuantiFERON-TB test at screening (if QuantiFERON-TB test is positive, the patient can only be included if active TB is ruled out with appropriate measurements according to standard of care, e.g. the patient is pre-treated with isoniazide for 4 weeks). No participation in other clinical trials 4 weeks before and after participation in this study |
