Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Sjogrens Syndrome
• Date of first enrollment: 28/03/2025

• Study type: Interventional

Intervention(s)

Nipocalimab:Nipocalimab SC:Participants will receive nipocalimab subcutaneously(SC) along with standard of care treatments. At the Week 48 visit, eligible participants from both studies will have the option to enter an open-label long-term extension (OLE) phase, where they will continue to receive nipocalimab until Week 143 or until the study intervention is discontinued and participants opt to withdraw from the study.

Placebo:Placebo SC:Participants will receive placebo subcutaneously along with standard of care treatments. At the Week 48 visit, eligible participants from both studies will have the option to enter an OLE phase,where they will receive nipocalimab until Week 143 or until the study intervention is discontinued and participants opt to withdraw from the study.

Outcome(s)

• Primary Outcome: Change from Baseline in Clinical European League Against Rheumatism Sjogren's Syndrome Disease Activity Index (ClinESSDAI) Score at Week 48: Baseline to Week 48: ClinESSDAI is a validated tool used in clinical studies to measure the systemic disease activity in participants with SjD. The ClinESSDAI includes 11 domains divided into 3-4 activity levels, where zero represents no activity and low, medium, and high scores can vary in numerical value depending on the domain being measured. A higher score represents worse disease symptoms.

Secondary Outcome

-Improvement from Baseline in Minimal Clinically Important Improvement (MCII) in ClinESSDAI Score at Week 48: Baseline to Week 48: The ClinESSDAI is a validated tool used in clinical studies to measure the systemic disease activity in participants with Sjogren's syndrome.
-Improvement from Baseline in ClinESSDAI Score at Week 48 in Participants with High Immunoglobulin (IgG) Levels at Baseline: Baseline to Week 48: ClinESSDAI is a validated tool used in clinical studies to measure the systemic disease activity in participants with SjD.
-Change from Baseline in ClinESSDAI Score at Week 8: Baseline to Week 8: ClinESSDAI is a validated tool used in clinical studies to measure the systemic disease activity in participants with SjD.
-Change from Baseline in Stimulated Salivary Flow Rate at Week 48: Baseline to Week 48: Stimulated salivary flow is considered a reliable and objective method to evaluate glandular function in SjD patients.
-Change from Baseline in Sjogren's Symptoms Dryness Score at Week 48: Baseline to Week 48: Participants will be asked to report the worst severity of their dryness symptoms on a 0 to 10 numeric rating scale (NRS), with score 0 indicating "No [specific symptom] " and score 10 indicating "Severe [specific symptom] ". Higher scores reflect greater symptom severity. Change from baseline in Sjogren' s Symptoms dryness score at Week 48 for US, US reference regions, and other non-US regions will be reported.
-Change from Baseline in Sjogren's Symptoms Joint Pain Score at Week 48: Baseline to Week 48: Participants will be asked to report the worst severity of their joint pain symptoms on a 0 to 10 numeric rating scale (NRS), with score 0 indicating "No [specific symptom] " and score 10 indicating "Severe [specific symptom] ". Higher scores reflect greater symptom severity. Change from baseline in Sjogren's Symptoms joint pain score at Week 48 for US, US reference regions, and other non-US regions will be reported.
-Change from Baseline in EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI) Score Through Week 48: Baseline through Week 48: ESSPRI is a participant-reported assessment of the severity of dryness, fatigue, and pain associated with primary Sjogren's Syndrome. Participants are asked to rate the severity of dryness, fatigue, and pain on a 0 to 10 NRS, with score 0 indicating "No [specific symptom]" and score 10 indicating "Severe [specific symptom]". A global score, calculated as the mean of the 3 domain scores, ranges from 0 to 10, with higher scores reflecting greater (worse) symptom severity. Change from baseline in Sjogren's Symptoms score at Week 48 for EU, UK & EU reference regions will be reported.
-Change from Baseline in Functional Assessment of Chronic Illness Therapy Fatigue (FACIT) Fatigue Score at Week 48: Baseline to Week48: FACIT-Fatigue version 4.0 is a 13-item questionnaire that assesses participant-reported fatigue and its impact upon daily activities and function over the past 7 days. Participants will be asked to answer each question using a 5-point Likert scale (0=Not at all; 1=A little bit; 2=Somewhat; 3=Quite a bit; and 4=Very much). FACIT-Fatigue has a total score range from 0 to 52, with 0 being the worst possible score and 52 the best.
