Inclusion criteria

Inclusion criteria: AGE 1. Age =18 years, at the time of signing the informed consent. TYPE OF SUBJECT AND DIAGNOSIS INCLUDING DISEASE SEVERITY 2. Documented Primary Sjögren’s Syndrome by American European Consensus Group criteria including: - either SS-A or SS-B positive. 3. Baseline unstimulated salivary flow >0.0 mL/min or evidence of glandular reserve function (stimulated baseline salivary flow >0.05 mL/min). 4. Symptomatic oral dryness (=5/10 on subject completed Numeric Response Scale) 5. Systemically active disease, ESSDAI =5 points. OR (for sites in ITALY ONLY) Systemically active disease, ESSDAI=5 points and with at least: a) 1 extraglandular domain moderate, OR b) 2 extraglandular domains low. SEX 6. Male and female subjects; females of child bearing potential are eligible if using effective contraception: Female subject is eligible to participate if she is not pregnant (as confirmed by a negative urine human chorionic gonadotropin (hCG) test), not lactating, and at least one of the following conditions applies: a. Non-reproductive potential defined as: -Pre-menopausal females with one of the following: -Documented tubal ligation -Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion -Hysterectomy -Documented Bilateral Oophorectomy - Postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) and estradiol levels consistent with menopause (refer to laboratory reference ranges for confirmatory levels)]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study; otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment. b. Reproductive potential and agrees to follow one of the options listed below in the GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) requirements from 30 days prior to the first dose of study medication up to Week 68 after Day 0. GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) This list does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penilevaginal intercourse on a long term and persistent basis. -Contraceptive subdermal implant that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label -Intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label -Combined estrogen and progestogen oral contraceptive -Injectable progestogen -Contraceptive vaginal ring -Percutaneous contraceptive patches -Male partner sterilization with documentation of azoospermia prior to the female subject's entry into the study, and this male is the sole partner for that subject. These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception. OTHER CRITERIA 8. For FRAN
