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

Phase 1RecruitingNCT06737380

LiveKidney.Bio10 enrolled

Overview

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.

Interventions

Physical examinationDIAGNOSTIC_TEST

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.

ElectrocardiogramDIAGNOSTIC_TEST

A twelve-lead electrocardiogram (ECG), including corrected QT interval (QTc interval), will be performed in all participants at the Screening visit.

SF-36 questionnaireOTHER

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.

Clinical laboratory evaluations - SerologyDIAGNOSTIC_TEST

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.

Clinical laboratory evaluations - BiochemistryDIAGNOSTIC_TEST

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.

Clinical laboratory evaluations - HematologyDIAGNOSTIC_TEST

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.

Pregnancy TestDIAGNOSTIC_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 fallopian tubes removed.

UrinalysisDIAGNOSTIC_TEST

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.

SLE activity evaluationDIAGNOSTIC_TEST

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.

SLE biomarker profilingDIAGNOSTIC_TEST

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 subsets

Cytokines and chemokine profilingDIAGNOSTIC_TEST

Samples will be analyzed for the following cytokines/chemokines: IFNγ, IL-6, IL-10, IL-18, TNFα, TGFβ1, CXCL10, CCL2, N-GAL, urine endothelin, KIM1. Serum and urine samples will be collected on Days 0, 28, 56, 140, 168, and early termination visit.

single dose of UC-MSCsBIOLOGICAL

participants will be treated on Baseline Day 1 with a UC-MSCs product administered subcutaneously. Participants will be observed for 2 to 3 hours after end of study treatment and then followed up for safety assessments over the subsequent 6-month period.

PROMIS instrumentsOTHER

PROMIS Fatigue, PROMIS, Depression, PROMIS Pain prior to dosing and/or any other clinical assessments, on visits 1 (baseline, day 0), visit 5 (day 14), visit 6 (day 28), visit 11 (day 168) and early termination visit.

Outcomes

Primary Outcomes

Incidence of Treatment-Emergent Adverse Events

Analysis for the primary endpoint will be descriptive in nature. safety and tolerability will be measured by the number of AEs and SAEs observed. Adverse event incidents will be summarized descriptively. The severity grade of each recorded AE, and their relationship to study treatment will be analyzed. The action taken and outcome will also be analyzed accordingly.

Time frame: day 1 to day 168

Secondary Outcomes

Change from baseline in the SLEDAI 2K following administration

Total score ranging from 0 to 105. Interpretation: Scores are categorized to indicate disease activity: 0: No activity 1-5: Mild activity 6-10: Moderate activity 11-19: High activity ≥20: Very high activity Improvement is defined as a decrease in score.

Time frame: day 1 to day 168

Change from baseline in PROMIS(Patient-Reported Outcomes Measurement Information System) score

Change from baseline in scores for quality of life, fatigue, pain, and depression as reported by the patient. Scores range from 0 to 100. Higher scores indicate worse symptoms.

Time frame: day 1 to day 168

Change from baseline in the BILAG-2004 Index score following administration

Organ involvement is categorized into grades: A: Severe active disease B: Moderate active disease C: Stable disease D: Resolved disease E: No involvement Improvement is defined as an increase in score.

Time frame: day 1 to day 168

Efficacy by SRI-4 Responder assessment at Day 168.
