Sjogren's syndrome (SS) is a chronic, multisystem autoimmune disease characterized by lacrimal and salivary gland inflammation, with resultant dryness of the eyes and mouth and occasional glandular enlargement. In addition, a variety of systemic manifestations may occur; including fatigue, musculoskeletal symptoms, rashes, and internal organ (e.g., pulmonary, renal, hepatic, and neurologic) disease. Sjogren's syndrome may occur in isolation, primary Sjogren's syndrome (pSS), or in a secondary form, often associated with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), or systemic sclerosis. Ravagalimab is an investigational drug being developed to help treat patients with inflammatory diseases like SS. This study will evaluate how well ravagalimab works within the body and how safe it is in patients with primary SS (pSS).
Ravagalimab, a potent CD40 antagonist is an investigational drug being developed for the treatment of Sjogren's syndrome (SS). This study is "double-blinded", which means that neither the trial participants nor the study doctors will know who will be given which study drug. Study doctors put the participants in 1 of 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. Participants 18-75 years of age with Sjogren's syndrome (SS) will be enrolled. Around 45 participants will be enrolled in the study in multiple sites within Netherlands.
Participants will receive ravagalimab intravenous (IV) loading dose or IV placebo at baseline followed by subcutaneous (SC) ravagalimab or matching placebo for 22 weeks.
There will be a higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, labial gland (lip) biopsy, and checking for side effects and completing questionnaires.

AbbVie is committed to responsible data sharing regarding the clinical trials we sponsor. This includes access to anonymized, individual and trial-level data (analysis data sets), as well as other information (e.g., protocols and clinical study reports), as long as the trials are not part of an ongoing or planned regulatory submission. This includes requests for clinical trial data for unlicensed products and indications.
Data requests can be submitted at any time and the data will be accessible for 12 months, with possible extensions considered.
Access to this clinical trial data can be requested by any qualified researchers who engage in rigorous, independent scientific research, and will be provided following review and approval of a research proposal and Statistical Analysis Plan (SAP) and execution of a Data Sharing Agreement (DSA).

| Change From Baseline in EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI) | ESSPRI is designed to evaluate the patient symptoms with 3 questions related to the dryness, pain and fatigue a participant has experienced in the prior 2 weeks. It is a numeric rating scale from 0 - 10, with a final score the mean of the 3 questions | Up to Week 24 |
| Change From Baseline in Tender Joint Count | An assessment of 68 joints will be done for tenderness by pressure manipulation on physical examination. Joint pain/tenderness will be classified as: present, absent, replaced or no assessment. | Up to Week 24 |
| Change From Baseline in Swollen Joint Count | An assessment of 66 joints will be done by directed physical examination. The joints to be examined for swelling are the same as those examined for tenderness, except the hip joints are excluded. Joint swelling will be classified as present, absent, replaced or no assessment. | Up to Week 24 |
| Change From Baseline in Salivary Flow (Unstimulated) | Patients will be asked to collect their saliva in a cup every 30 seconds for a total period of 5 minutes. The saliva production is expressed in ml/minute. | Up to Week 24 |
| Change From Baseline in Salivary Flow (Stimulated) | Saliva production is stimulated by parafilm and collected in a cup every 30 seconds for a total period of 5 minutes.. The saliva production is expressed in ml/minute. | Up to Week 24 |
| Change From Baseline in Lacrimal Flow (Schirmer's Test of Ocular Function) | Lachrymal flow will be assessed by Schirmer's test of ocular function. A small filter paper will be placed in the conjunctival sac for 5 minutes. After that, the degree of wetting is evaluated | Up to Week 24 |
| Change From Baseline in Van Bijsterveld Score | The van Bijsterveld score is an ocular score for dryness. The Bijsterveld score is determined by adding up the combined score (from 0 to 3; 0 is normal and 3 is the highest level of staining) in the central and two outer sections of the eye. | Up to Week 24 |
| Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) | FACIT-Fatigue is a 13-item questionnaire that evaluates fatigue/tiredness and its impact on daily activities and functioning in chronic diseases. This instrument includes items such as tiredness, weakness, listlessness, lack of energy, and the impact of these feelings on daily functioning (e.g., sleeping, and social activities).
