A Single and Repeat Dosing Study of the Safety, Drug Exposure and Clinical Activity of R-2487 in Patients With Sjogren's Syndrome (SjD)

The goal of this study is to determine the safety and tolerability of orally taken probiotic (R-2487) in patients with Sjogren's Syndrome.

Patients will take an oral dosage of probiotic (R-2487) and physicians will assess and measure their Sjogren's Syndrome. Blood and fecal evaluations of inflammation and assessment of probiotic (R-2487) on fecal level will also be measured.

All female subjects who are biologically capable of having children must have a negative pregnancy test result before administration of investigational product; The use of probiotics prior to study enrollment is accepted; however, during the course of the study, the use of probiotics is forbidden.

Exclusion: Prior allogenic or autologous bone marrow or organ transplantation; Subjects with prior irradiation to the head and neck, including radioactive iodine treatment for hyperthyroidism; Prior immunotherapy, biologics, or investigational therapy must have completed at least 5 half-lives or 30 days, whichever is longer, prior to the first dose of R-2487 DP; Subjects should not receive any of the following medications:; Rituximab or belimumab within 6 months prior to Day 1 Abatacept within 3 months prior to Day 1 Infliximab, Adalimumab, Certolizumab, Tocilizumab, Cyclosporine, or Mycophenolate mofetil within 2 months prior to Day 1 Etanercept, Anakinra, Immunoglobulin, or blood products within 28 days prior to Day 1; No known active overlapping or associated other autoimmune disease; Subjects with positive results for human immunodeficiency virus (HIV), hepatitis A virus (HAV), hepatitis B virus (HBV), or hepatitis C virus (HCV); Subjects with active viral, bacterial, or fungal infection, or history of severe opportunistic infection within the preceding 3 months, or COVID-19 infection in the past 3 months; Subjects with evidence of active or latent tuberculosis; Active infection of the salivary or lacrimal glands; Any form of vaccination in the last 30 days, to include but not limited to influenza, COVID, shingles, tetanus, hepatitis, pneumonia, HPV, DPT, MMR, and polio; Subjects who have a present malignancy or previous malignancy within the last 5 years prior to screening (except documented history of cured non-metastatic squamous or basal cell skin carcinoma or cervical carcinoma in situ). Subjects who had a screening procedure that is suspicious for malignancy, and in whom the possibility of malignancy cannot be reasonably excluded following additional clinical, laboratory or other diagnostic evaluations; Current clinical findings of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, pulmonary, cardiac, endocrine, neurological, or cerebral disease with laboratory values as following:; Hemoglobin level < 9.0 g/dL; Absolute white blood cell (WBC) count of <3.0×109/L (<3000/mm3), or absolute neutrophil count of <1.2×109/L (<1200/mm3), or absolute lymphocyte count of <0.8×109/L (<800/mm3); Thrombocytopenia, defined by platelet count <100×109/L (<100,000/mm3); Chronic kidney disease defined as Estimated glomerular filtration rate (eGFR) <60 mL/min/1.73m2, based on the age appropriate calculation; Proteinuria ≥3+; Total bilirubin (T-bili), aspartate aminotransferase (AST), alanine aminotransferase (ALT) more than 1.5 times upper limit of normal (ULN); Previously diagnosed hepatic cirrhosis (Child Pugh A or higher) or previously diagnosed significant liver fibrosis (> F3); Prior immunotherapy, including systemic corticosteroids, such prednisone, biologics, Janus kinase (JAK) inhibitors (such as tofacitinib, or upadacitinib), ozanimod, or investigational therapy must have completed at least 5 half-lives or 30 days, whichever is longer, prior to Day 0, unless otherwise specified.
