E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To assess the safety and tolerability of multiple intravenous infusion of CFZ533 in patients with primary Sjögren’s syndrome as measured by adverse events (AEs).
• To compare the effect of multiple intravenous infusion of CFZ533 versus placebo on the clinical disease activity of primary Sjögren’s syndrome patients as measured by the change of an EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) after 12 weeks treatment. |
|
E.2.2 | Secondary objectives of the trial |
• To assess the safety and tolerability of multiple subcutaneous doses of CFZ533 in patients with primary Sjögren’s syndrome as measured by adverse events (AEs).
• To compare the effect of multiple subcutaneous doses of CFZ533 versus placebo on the clinical disease activity of primary Sjögren’s syndrome patients as measured by the change of an EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) after 12 weeks treatment.
• To assess the pharmacokinetics of multiple subcutaneous doses and multiple intravenous infusion of CFZ533 in primary Sjögren’s syndrome patients.
Other protocol defined inclusion criteria may apply; |

E.4 | Principal exclusion criteria |
• Secondary Sjögren’s syndrome. Patients with laboratory or clinical signs of another connective tissue disease (e.g., systemic lupus erythematous) may be eligible at the investigators discretion;
• Use other investigational drugs at the time of enrollment, or is within five half-lives of using other investigational drugs or longer if required by local regulations, at the time of enrollment;
• History of hypersensitivity to study drug or to drugs of similar chemical classes;
• Patients having received the following treatments (within given timeframe before randomization):
Oral or i.v. cyclosphosphamide treatment within 6 months;
i.v. corticosteroid bolus with dose > 1 mg/kg within 3 months;
Rituximab within 12 months. For patient who received rituximab earlier, B cell count should be within normal range;
Belimumab within 6 month;
Any other biologic within 1 month or five times the half-life, whichever is longer;
Any other immunosuppressives (despite methotrexate, glucocorticoids, and
hydroxychloroquine on stable doses as described in the inclusion criteria 8, 9, 10, 11) such as cyclosporine A or mycophenolate within 3 months;
• Patients where the primary cause of sicca symptoms (e.g. dry mouth, dry eyes) as judged by the investigator, is attributable to a medication used regularly or intermittently (rather than to primary Sjogren`s syndrome)
• Patients who are at significant risk for thromboembolic events as judged by the investigator or have any one of the following:
History of either thrombosis or 3 or more spontaneous abortions with or without the presence of anti-cardiolipin autoantibodies;
Presence of lupus anticoagulant or prolonged partial thromboplastin time (PTT);
• Pancreatic injury or pancreatitis as indicated by abnormal signs or symptoms of pancreatitis or clinically significant elevations in amylase or lipase;
• History or presence of any medically significant cardiac condition which according to the investigator may jeopardize the patient in case of participation in the study, including ischemic heart disease, heart failure, cardiomyopathy, myocardial infarction or stroke;
• Sitting vital signs outside of the following ranges at screening or baseline: body temperature: 35.0 - 37.5°C, systolic blood pressure: 90 - 145 mmHg, diastolic blood pressure: 50 - 90 mmHg, pulse rate 50 - 100 bpm.
• History of malignancy of any organ system (other than localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases;
• Signs or symptoms of a clinically significant systemic viral, bacterial or fungal infection within 30 days of randomization;
Other protocol defined exclusion criteria may apply. |
