NCT06297213

Brief Summary

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.

  • Prior allogenic or autologous bone marrow or organ transplantation
  • Subjects with prior irradiation to the head and neck, including radioactive iodine treatment for hyperthyroidism
  • 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.
  • 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
  • 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
  • Pregnant or breastfeeding women
  • 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.
  • +7 more criteria
