UC-MSC Cell Therapy Study for Systemic Lupus Erythematosus (SLE) Patients

Официальное название

A Phase I, Open-Label Study to Evaluate the Safety and Tolerability of Subcutaneous Administration of Umbilical Cord Derived - Mesenchymal Stromal Cell Therapy in Addition to Standard of Care as A Treatment For Active Systemic Lupus Erythematosus

Обзор

The goal of this clinical trial is to evaluate the safety and effectiveness of UC-MSCs in adults with systemic lupus erythematosus (SLE). The main questions this study aims to answer are: 1. Can UC-MSCs improve kidney function and reduce SLE disease activity? 2. Are UC-MSCs safe and well-tolerated in this patient population? Participants in this study will: * Receive UC-MSCs in a single dose in addition to standard of care treatment. * Provide blood and urine samples for laboratory assessments, including biomarkers and immune profiling (e.g., cytokines, complement proteins, and autoantibodies). * Attend regular clinic visits for physical exams, disease activity scoring, and imaging tests to monitor kidney health. * Complete assessments for safety, such as monitoring for adverse events and changes in laboratory values. This study aims to provide new insights into treatment options for SLE and lupus nephritis, addressing an unmet medical need in this population.

Вмешательства

• Диагностический тест Physical examination
  The physical examination will be performed at the Screening visit and at each subsequent study and safety in clinic follow-up visit. The exam will include: measurement of vital signs (heart rate, peripheral arterial blood pressure, respiratory rate, and temperature), weight, height (at Screening visit only), cardiovascular and respiratory systems, abdominal examination, skin evaluation, mouth and eye evaluation, and neurological assessment. Abnormal findings will be recorded in the CRF.
• Диагностический тест Electrocardiogram
  A twelve-lead electrocardiogram (ECG), including corrected QT interval (QTc interval), will be performed in all participants at the Screening visit.
• Другое SF-36 questionnaire
  Patients will fill out the SF 36 survey, assessing physical and mental health outcomes prior to dosing and/or any other clinical assessments, on visits 1 (baseline), visit 5 (day 14), visit 6 (day 28), visit 11 (day 168) and early termination visit.
• Диагностический тест Clinical laboratory evaluations - Serology
  Serologic testing for HIV, HBV, HCV, TB, and CMV will be performed; HBV and HCV PCR will be done only if serology is positive. Autoimmune tests (ANA, anti-ENA, total IgG, anti-nucleosome) will be done at Day 0 and end of study; ANA only at Screening if no positive ANA or anti-dsDNA in prior 6 months. Inflammatory markers (hs-CRP, ESR) will be tested at Day 0 and end of study. CBC with differential, biochemistry, anti-dsDNA, and complement C3/C4 will be assessed at each scheduled visit.
• Диагностический тест Clinical laboratory evaluations - Biochemistry
  The panel will include analysis of albumin, blood urea nitrogen (BUN), creatinine, glucose, uric acid, calcium, phosphorus, potassium, sodium, lactate dehydrogenase (LDH), total protein, magnesium, alkaline phosphatase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin and hs-CRP. For biochemistry, 3 mL blood will be collected at each study visit. Results relating to inclusion criteria must be confirmed within 7 days prior to Day 1.
• Диагностический тест Clinical laboratory evaluations - Hematology
  The complete blood count (CBC) will include: hemoglobin, hematocrit, white blood cells (WBCs) with complete manual or automated differential (total neutrophils, lymphocytes, monocytes, eosinophils, basophils; absolute or percentage will be acceptable), red blood cells (RBCs), platelet count. For CBC, 1mL blood will be collected at each study visit.
• Диагностический тест Pregnancy Test
  A serum b-hCG pregnancy test will be performed for women of child-bearing potential at the Screening visit;urine pregnancy tests will be performed for women of child-bearing potential at each study visit noted above, including on Day 0 prior to study treatment. Pregnancy tests are not required for women unable to become pregnant for one of the following reasons: Menopause confirmed by healthcare provider, verbally reported by a participant that she has had her uterus or both ovaries or both fal
• Диагностический тест Urinalysis
  General urinalysis will include analysis of pH, specific gravity, protein, glucose, ketones, bilirubin, urobilinogen, leukocytes, erythrocytes. In addition samples will be assessed for presence of urinary casts. Spot urine protein/creatinine measure will be done at each visit. If no casts are observed at Screening, then machine assessment of further urinary samples is allowed. For urinalysis, 10mL urine will be collected at each study visit.
• Диагностический тест SLE activity evaluation
  SLE status will be assessed using the Safety of Estrogens in Lupus Erythematosus National Assessment- SLE Disease Activity Index (SLEDAI 2K scale).SLE activity will also be assessed using British Isles Lupus Assessment Group (BILAG), physician global and participant global assessment allowing use of the Systemic Lupus Responder Index (SRI 4) and the BILAG-based Composite Lupus Assessment (BICLA) instruments to assess clinical response.
• Диагностический тест SLE biomarker profiling
  SLE biomarkers will be profiled at the study visit (Day 1) and at every subsequent follow up visit. For this purpose, urine and 10 ml blood will be collected. Anti-ENA, Anti-dsDNA antibodies, total serum IgG levels, CBC, C3, C4, anti-nucleosome antibodies, erythrocyte sedimentation rate, CRP, protein/creatinine ratio in spot urine, 24-hour urine protein - Day 1 - Baseline and at end of study visit only; Mononuclear cell changes. This analysis includes lymphocyte subsets and innate immune cell s
