Trial outcomes

Primary outcomes

1

Change from baseline in ESSDAI score compared with placebo.

ESSDAI is a validated clinical disease activity index for Sjögren's syndrome. It includes 12 organ-specific domains, each scored by the investigator according to severity using 3- or 4-level scales. Weighted domain scores are summed to generate a total score (maximum score: 123). Domains include constitutional, lymphadenopathy, glandular, articular, cutaneous, pulmonary, renal, muscular, peripheral nervous system, central nervous system, hematological, and biological domains. Higher scores on the ESSDAI scale are associated with poorer health states.

Time frame
Up to approximately 25 weeks
