Background:

An autoimmune disease is one in which the immune system attacks a person s own body. Sjogren's syndrome (SS) is an autoimmune disease. It often involves multiple systems and organs of the body. Researchers are trying to find new, more effective and safe treatments for SS.

Objective:

To evaluate the safety and tolerance of tofacitinib in people with SS.

Eligibility:

Adults ages 18-75 with SS.

Design:

Participants will be screened on a separate protocol. They will undergo:

-Medical and dental history

-Physical exam

-Medicine review

-Electrocardiogram to test the heart s electrical activity (Participants will lay on a table. Sticky pads will be placed on their body.)

-Eye exam and test for dry eyes

-Oral, head, and neck exams

-Plaque collection (Dental plaques and tongue and mucosal scrapings will be collected using a small tongue depressor.)

-Salivary gland ultrasound

-Blood and urine tests

-Minor salivary gland biopsy (The lower lip will be numbed. Several tiny salivary glands will be removed through a small incision.)

-Saliva collection

-Disease assessment.

Participants will repeat some of the screening tests during the study.

Participants will take capsules of the study drug or a placebo by mouth for 168 days.

Participants will have tests to measure blood pressure and the speed of blood flow through the organs. They will also have a test that examines the function and reaction of the blood vessels. For these tests, they will wear blood pressure cuffs and other sensors.

Participants will complete questionnaires about their health.

Participants will have 9 study visits over 28 weeks. They may be contacted by phone between study visits.

Eligibility

INCLUSION CRITERIA:

Adult primary SS participants with mild-to-moderate disease activity will be eligible for this study. Enrolled participants can be na(SqrRoot) ve or failed immunosuppressive therapy beyond antimalarials and glucocorticoids; to prevent bias in the cohort of participants with more

recalcitrant disease. We expect that Tofacitinib is a potential second line therapy, in addition to antimalarials and glucocorticoids, depending on the participant s initial presentation and response. Women and members of minority groups, if eligible, will be included in accordance with the NIH Policy on Inclusion of Women and Minorities as Participants in Research Involving Human Participants.

In order to be eligible to participate in this study, an individual must meet all of the following criteria:

1. Ability of participant to understand and the willingness to sign a written informed consent document.

2. Participation and enrollment in companion protocol, 15-D-0051, Characterization of Diseases with Salivary Gland Involvement.

3. Stated willingness to comply with all study procedures and availability for the duration of the study

4. Male or female, aged between 18-75 years

5. In good general health as evidenced by medical history

6. Meets the 2002 American European Consensus Group classification criteria for primary Sjogren's Syndrome or 2016 American College of Rheumatology/European League against Rheumatism Classification Criteria (ACR-EULAR) with mild to moderate disease activity defined as ESSDAI between 0 to 13 at the screening visit and >0 ml/min/gland stimulated saliva flow.

7. Ability to take oral medication and be willing to adhere to the study intervention regimen

8. If on glucocorticoids, the dose must be less than 10 mg daily and stable for the 4 weeks (28 days) prior to screening visit.

9. If on hydroxychloroquine or other antimalarials such as chloroquine or quinacrine, the dose must have been stable for the 12 weeks (96 days) prior to screening visit. The maximum allowed dose is hydroxychloroquine up to 400 mg/day or 6.5 mg/kg/day if more than 400 mg/day. The maximum allowed dose for chloroquine phosphate is up to 500 mg daily and for quinacrine up to 100 mg daily.

10. Participants may be on lipid lowering medications if initiated at least 3 months prior to the screening visit and dose must be stable for 4 weeks (28 days) prior to study entry.

11. Males and females with potential for reproduction must agree to practice effective birth control measures. Females should be on adequate contraception if they are of child-bearing potential documented by a clinician, unless participants or spouse have previously undergone a sterilization procedure. Adequate birth control measures are: intrauterine device (IUD) alone or hormone implants, hormone patches, injectable, or oral contraceptives plus a barrier method (male condom, female condom or diaphragm), abstinence or a vasectomized partner.

12. Agreement to adhere to Lifestyle Considerations throughout study duration

EXCLUSION CRITERIA:

In order to be eligible to participate in this study, an individual must not meet any of the following criteria:

1. Current or prior treatment with rituximab, belimumab or any other biologic agent in the 6 months prior to screening.

2. Current treatment with methotrexate, azathioprine, mycophenolate mofetil, cyclosporine, tacrolimus, or other less common immunomodulatory drugs such as those falling into the class of disease-modifying antirheumatic drugs (DMARDs), not otherwise specified herein. Participants previously on methotrexate, azathioprine, mycophenolate mofetil, cyclosporine or tacrolimus, or other DMARDs should have withdrawn drug for at least 8 weeks (56 days) at the time of screening.

3. Treatment with cyclophosphamide, pulse methylprednisolone or IVIG within 6 months prior to screening.

4. Current treatment with potent inhibitors of Cytochrome P450 3A4 (CYP3A4) (e.g., ketoconazole) or receiving one or more concomitant medications that result in both moderate inhibition of CYP3A4 and potent inhibition of CYP2C19 (e.g., fluconazole) that would increase serum availability of Tofacitinib. Past treatment with the aforementioned agent is allowed if it was more than a week prior to the administration of the first dose of study medication.

5.History of chronic liver disease, not including well-controlled Sjogren s-related chronic liver disease or elevated LFTs:

-ALT or AST >= 2x upper limit of normal at screening

-Serum unconjugated bilirubin > 2mg/dL at screening

6. Serum creatinine >1.5mg/dL.

8. Active urinary sediment (WBC, RBC or mixed cellular casts 1+ or more /hpf).

9. Hypercholesterolemia: Values after 8-12 hour fasting blood specimen: total cholesterol >250 mg/dL or LDL >180 mg/dL or hypertriglyceridemia (triglyceride >300 mg/dL) within-45 days of screening visit.

17. Known active tuberculosis. Participants with treated latent tuberculosis (LTB) will be eligible to participate. Participants with untreated LTB will not be excluded but will be evaluated by an infectious disease (I.D.) consultant and may become eligible for trial based on infectious disease consultant recommendations.

18. History of opportunistic infections.

19. Participants with active renal or central nervous system disease or a high activity level in any organ system (except articular) in ESSDAI^54.
