    • iscalimab (anti-CD40)
    • belimumab (anti-BAFF mAb)
    • Active viral, bacterial or other infections
    • History of major organ, hematopoietic stem cell or bone marrow transplant
    • History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes (e.g., mAb of IgG1 class) or to any of the constituents of the study drug formulation (sucrose, L-histidine hydrochloride/L-histidine, polysorbate 20)
    • Required regular use of medications known to cause dry mouth/eyes as a regular and major side effect, and which have not been on a stable dose for at least 30 days prior to Screening, or any anticipated change in the treatment regimen during the course of the study
    • Receipt of live/attenuated vaccine within a 4-week period prior to baseline
    • History of primary or secondary immunodeficiency, or a positive HIV (ELISA and Western blot) test result
    • History of malignancy of any organ system (other than localized basal cell carcinoma of the skin, in situ cervical cancer), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases.
    • History of head and neck radiation therapy or of having received radioactive iodine
    • Any one of the following screening values of CBC laboratory values
      • Hemoglobin levels below 8.0 g/dL;
      • Total leukocyte count less than 2,000/μL;
      • Platelets <50 x 109/L (if between 50 and 80, the PI should check that it is linked to Sjögren's syndrome and not to any other disease);
      • Absolute neutrophil count (ANC) <1.0 x 109/L (one re-test is allowed during the screening period)
      • Positive serology for hepatitis B surface antigen (HBsAg).
      • Positive serology for hepatitis B core antibody (HBcAb), except if all 3 following criteria are met
        • Hepatitis B (HBV) quantitative PCR for viral DNA is negative (i.e., <10 IU)
        • Prophylactic treatment (with tenofovir or entecavir) initiated latest on day 1 and continued until 12 months after last treatment
        • Hepatitis B monitoring is implemented: HBsAg (and HBV DNA) tested every 4 weeks during treatment and at least every 12 weeks after end of treatment for the entire duration of the follow-up. Antiviral prophylaxis must be implemented while on study and up to 12 months after end of study treatment.
        • Positive hepatitis C test result. Participants with a positive HCV antibody test should have HCV RNA levels measured. Participants with positive (detectable) HCV RNA should be excluded.
        • Evidence of active tuberculosis (TB) infection (after anti-TB treatment, patients with history of or latent TB may become eligible according to national guidelines)
        • Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test
        • Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 6 months after stopping of investigational medication. Highly effective contraception methods include
          • Total abstinence (when this is in line with the preferred and usual lifestyle of the patient). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
          • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) total hysterectomy or tubal ligation at least six weeks before taking investigational drug. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
          • Male sterilization (at least 6 months prior to screening and confirmed as successful). For female patients in the study, the vasectomized male partner should be the sole partner for that patient
          • Use of oral, (estrogen and progesterone), injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS) or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception. In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking investigational drug.
          • Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
          • If local regulations deviate from the contraception methods listed above to prevent pregnancy, local regulations apply and will be described in the informed consent form (ICF).
          • Known contraindication to SonoVue (sulphur hexafluoride microbubbles) ultrasound contrast agent
          • Participants not registered in the social security system
          • Participants within the exclusion period of a preceding study
          • Any surgical, medical (e.g. uncontrolled hypertension, heart failure or diabetes) psychiatric or additional physical condition that the investigator feels may jeopardize the patient in case of participation in this study
          • People deprived of their liberty by a judicial or administrative decision (Article L1121-6 of the French Public Health Code)
          • Screening Labial minor salivary gland (LMSG) biopsy lymphocyte focus score < 0.3/4 mm2 or B/B+T ratio in the gland < 0.2 (20%)
          • Use of topical ocular prescription medications (excluding artificial tears, gels, lubricants) that have not been on a stable dose for at least 90 days prior to treatment, or any anticipated change in the treatment regimen during the course of the study
