8. Female participant of childbearing potential or male participant must agree to use highly effective contraception/preventive exposure measures.

Key Exclusion Criteria:

1. Secondary Sjögren's syndrome according to the ACR-EULAR (2016) classification.

2. History or presence of unstable condition not related to Sjögren's Syndrome that, in the opinion of the investigator, could constitute an unacceptable risk when taking the IP or interfere with the interpretation of data.

3. Participant has any active systemic infection within 2 weeks prior to first IP dosing, or poorly controlled chronic cardiac, pulmonary, or renal disease.

4. Participant has a known or suspected history of or a current immunosuppressive condition, or a history of opportunistic infections (e.g., human immunodeficiency virus [HIV] infection, histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, aspergillosis).

5. Participant has a chronic hepatitis B virus (HBV) infection, as defined by persistent HBV surface antigen (HBsAg) positivity. Participant has hepatitis C virus (HCV) infection, as defined by positive HCV antibody at screening and detectable HCV viremia. Participants with positive HCV antibody must undergo reflex HCV ribonucleic acid (RNA) testing, and participants with HCV RNA positivity will be excluded. Participants with positive HCV antibody and negative HCV RNA are eligible.

Participants presenting any signs or symptoms of SARS-CoV-2 infection, as detected prior to first IP dosing following careful physical examination (e.g., cough, fever, headaches, fatigue, dyspnea, myalgia, anosmia, dysgeusia, anorexia, sore throat, etc). In addition, any other locally applicable standard diagnostic criteria may also apply to rule out SARS-CoV-2 infection.

7. Participant has taken any disallowed therapies:

• Mycophenolate mofetil (MMF) within a week prior to screening.

• Cyclosporine/Tacrolimus within a week prior to screening.

• Cyclophosphamide within 6 months prior to screening.

• Ocular medicines (e.g., topical cyclosporine, topical NSAIDs/ corticosteroids) for at least 4 weeks prior to screening, except for a sporadic use.

• Biologics such as, but not limited to, rituximab, abatacept, and any other unapproved biologic within 6 months prior to screening.

• Plasmapheresis within 12 weeks prior to screening.

• Plasma exchange within 12 weeks prior to screening.

• Intravenous immunoglobulin (IVIG) therapy within 24 weeks prior to screening.

• Other prohibited medications within 2 weeks or 5 half-lives, whichever is longer, prior to first IP dosing.

8. Concurrent use of anticholinergic agents or any other medication known to cause dry mouth/dry eyes that, in the opinion of the investigator, are a contributing factor to the participant's dryness and/or use of anticholinergic agents not contributing to this dryness, if not stable at least 4 weeks prior to screening.

9. Participant has a history of tuberculosis (TB) diagnosis or evidence of active or latent infection with Mycobacterium tuberculosis.

10. Participant has a history of lymphoma or any malignancy within the past 5 years prior to screening with the exception of excised and curatively treated non-metastatic basal cell carcinoma or squamous cell carcinoma of the skin or carcinoma in situ of cervix which is considered cured with minimal risk of recurrence.

11. Participant has severe organ manifestation or life-threatening condition, or has planned a surgery during the study.

Note: Other protocol-defined Inclusion/Exclusion criteria may apply.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in European League Against Rheumatism (EULAR) Sjögren's Syndrome Disease Activity Index (ESSDAI) Score at Week 12	The ESSDAI is a systemic disease activity index to assess 12 domains (organ systems: constitutional, lymphadenopathy and lymphoma, glandular, articular, cutaneous, pulmonary, renal, muscular, peripheral nervous system, CNS, hematological, biological) in participants with pSS. Each of the domains was assessed for activity level (no, low, moderate, and high). Each domain score was obtained by multiplying the activity level with the domain weight, ranged from 1 to 6, and assigned a numerical score based on pre-determined weighting of each individual domain. The sum of all individual weighted domain scores was the overall score, ranged from 0 (best) to 123 (worst activity). A higher score indicated more disease activity. A clinically meaningful reduction from baseline (=3 points) indicated the improvement of symptoms. Least squares (LS) mean was calculated using mixed models for repeated measures (MMRM).	Baseline, Week 12
Primary	Number of Participants Who Experienced Treatment Emergent Adverse Events (TEAEs) by Severity	An adverse event (AE) was any untoward medical occurrence in a participant administered study drug and which did not necessarily have a causal relationship with study drug. The severity of AEs was graded using the Common Terminology Criteria for Adverse Events (CTCAE) current version at the time of assessment. The maximum intensity of the AE were Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (life-threatening), or Grade 5 (fatal). A TEAE was any AE with an onset date on or after the first dose of GLPG3970 and no later than 30 days after last dose of GLPG3970, or any worsening of any AE on or after the GLPG3970 start date.	From first dose of study drug up to 30 days after last dose of study drug (maximum duration=16 weeks)
Secondary	Change From Baseline in EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) Score at Weeks 4, 8, and 12	The ESSPRI is a participant-reported questionnaire to assess subjective participant symptoms and includes 3 domains (dryness, pain, and fatigue). Each domain was scored on scale of 0-10 (0 = no symptom at all and 10 = worst symptom imaginable), and an overall score was calculated as the mean of the 3 individual domains where all domains carry the same weight. Minimum score can be 0 and maximum score can be 10. A higher score indicates worst symptom. A clinically significant reduction from baseline of the ESSPRI score (at least one point or 15% of the baseline value) indicated the improvement of symptoms.	Baseline, Weeks 4, 8, and 12
Secondary	Change From Baseline in ESSDAI Score at Weeks 4, 8, and 12	The ESSDAI is a systemic disease activity index to assess 12 domains (organ systems: constitutional, lymphadenopathy and lymphoma, glandular, articular, cutaneous, pulmonary, renal, muscular, peripheral nervous system, CNS, hematological, biological) in participants with pSS. Each of the domains was assessed for activity level (no, low, moderate, and high). Each domain score was obtained by multiplying the activity level with the domain weight, ranged from 1 to 6, and assigned a numerical score based on pre-determined weighting of each individual domain. The sum of all individual weighted domain scores was the overall score, ranged from 0 (best) to 123 (worst activity). A higher score indicated more disease activity. A clinically meaningful reduction from baseline (=3 points) indicated the improvement of symptoms. Results of Week 12 is presented in primary outcome measure 1.	Baseline, Weeks 4, 8, and 12
Secondary	Observed Pre-dose Plasma Concentration (Ctrough) of GLPG3970	Plasma concentration of GLPG3970 observed at pre-dose in nanogram per milliliter (ng/mL), obtained directly from the observed concentration versus time data.	Pre-dose (within 30 minutes prior to dosing) on Weeks 1, 4, 8, and 12
