Brief Summary

The purpose of this study is to evaluate the efficacy and safety of subcutaneous Telitacicept versus placebo in subjects with active primary Sjogren's Syndrome.

Detailed Description

This is a phase Ⅲ, multi-center, randomized, placebo-controlled, study. Subjects with active primary Sjogren's Syndrome (pSS) will be randomized to receive subcutaneous Telitacicept 80 mg, Telitacicept 160 mg or placebo weekly for a total of 48 weeks. Subjects are allowed to be transferred to another group after Week 24 by the investigator so that those randomized to the placebo group are able to receive either Telitacicept 80 mg or Telitacicept 160 mg afterwards. Subjects who are randomized to Telitacicept 80 mg and Telitacicept 160 mg groups will remain in the previous treatment group even if the investigator chooses to transfer them. Subjects and investigators are blinded throughout the study.

Primary Outcome Measures
NameTimeMethod
Change from baseline in ESSDAI scoreWeek 24

The EULAR Sjogren's syndrome (SS) disease activity index (ESSDAI) is a systemic disease activity index that was designed to measure disease activity in patients with primary SS. It includes 12 domains (ie, organ systems: cutaneous, respiratory, renal, articular, muscular, peripheral nervous system (PNS), central nervous system (CNS), haematological, glandular, constitutional, lymphadenopathic, biological). Each domain is divided into 3-4 levels of activity (no, low, moderate, high). Overall score is calculated as sum of all individual weighted domain scores (ranges from 0 (best) to 123 (worst activity). A higher score indicates worsening of the disease.

Secondary Outcome Measures
NameTimeMethod
Percentage of subjects with ESSPRI score decreased from baseline by at least 1 point or 15%Week 24 & Week 48

The EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI) is a patient-reported, subjective symptom index for primary Sjögren's syndrome. It consists of three questions covering the cardinal symptoms of Sjögren's syndrome: dryness, fatigue and pain (articular and/or muscular). Each domain scored on scale of 0-10 (0 =no symptom at all and 10 = worst symptom imaginable), and an overall score is calculated as the mean of the three individual domains.

Incidence of AEs, SAEsUp to Week 48

An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death; is life-threatening experience; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or is a congenital anomaly/ birth defect; or any other important medical event that may not be immediately life-threatening or result in death or hospitalization but may require intervention to prevent one of the other serious outcomes listed in the definition above.

Change from baseline in MFI-20Week 24 & Week 48

The multidimensional fatigue inventory (MFI-20) is a 20-item self-report instrument designed to measure fatigue. It covers the following dimensions: general fatigue, physical fatigue, reduced activity, reduced motivation and mental fatigue. Each question is scored from one to five and each dimension consists of five questions. The dimensional score consequently ranges from 4 to 20 (a higher score indicates more fatigue).
