The aim of this clinical trial is to evaluate the safety and efficacy of anti-BTLA agonist therapy (LY3361237) in treating patients with primary Sjogren's syndrome.\n\nThe primary objective is to evaluate the efficacy of LY3361237 in patients with primary Sjogren's syndrome by assessing changes in the Sjogren's Tool for Assessing Response (STAR) after 12 weeks of treatment.\n\nThe secondary objective is to determine the effect of LY3361237 on glandular changes measured by PET/MRI.", 'detailedDescription': "This study is a single-site, open-label study in subjects with primary Sjogren's syndrome being conducted at the Stanford University rheumatology clinic. All eligible subjects will receive LY3361237 450mg SC Q2W over a period of 12 weeks and will be followed up for an additional 10 weeks after the last dose. Twelve subjects will be included in the study.\n\nAfter the Screening visit, consenting patients will be seen in clinic on day 1 (Baseline) and return to clinic on Weeks 2, 4, 6, 8, 10, 12, and 22.\n\nAt Screening (up to 35 days before baseline), a complete medical history, physical exam, vital signs, clinical laboratory tests \\[comprehensive metabolic panel, complete blood count, quantitative immunoglobulins, ANA, RF, anti-Ro, anti-La, C3, C4, ESR, CRP, urinalysis, urine protein:creatinine, serum pregnancy test for females, HIV serologies, hepatitis B serologies, hepatitis C serologies, quantiFERON test for tuberculosis, SARS-CoV-2 PCR\\], chest x-ray, electrocardiogram, and salivary gland ultrasound will be conducted.\n\nAt all subsequent visits, at a minimum, a complete physical exam, vital signs, focused history, and clinical laboratory tests (comprehensive metabolic panel, complete blood count, ESR, CRP, and urine pregnancy test for females) will be conducted.\n\nEfficacy will be assessed using the Sjogren's Tool for Assessing Response (STAR) and by measuring changes in unstimulated salivary flow rate, changes in salivary glands by ultrasound, changes in salivary glands by PET/MRI, changes in Schirmer I testing, changes in laboratory values including inflammatory markers (ESR, CRP) complement levels (C3, C4), immunoglobulins (IgG, IgA, IgM), and autoantibodies (ANA, SS-A, SS-B, RF), and changes in patient reported outcomes.\n\nAt Screening, Baseline, Week 4, and Week 12, patients will record their global assessment of disease as well as visual analog scales for ocular and salivary symptoms and the ESSPRI. At Baseline, Week 4, and Week 12, patients will record the FACIT-F for fatigue and RAND SF-36, and the physician will calculate the ESSDAI, ClinESSDAI, physician global assessment of disease, and tender and swollen joint count.\n\nIn addition, safety will be assessed for all patients."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\nSubjects are eligible for enrollment in the study only if they meet all of the following criteria:\n\n* Have given written informed consent\n* Are men or women aged 18 to 85, inclusive, at the time of initial screening\n* Have a confirmed diagnosis of primary Sjogren's syndrome by the 2016 ACR-EULAR classification criteria for primary Sjogren's syndrome \\[2\\]\n* ≥50mm on a visual analog scale (VAS) for ocular dryness or oral dryness or ≥5 on the ESSPRI score for dryness\n* Have a Hočevar salivary gland ultrasound score (SGUS) (on a 0-48 point scale) and ≥10 \\[to detect relatively early disease with less anatomic derangement that will potentially be more responsive to treatment and to exclude patients with no changes on ultrasound that would preclude an ability to see improvement\\] \\[3\\]\n* All women (regardless of childbearing potential) must test negative for pregnancy at the time of screening.
