Lupus Nephritis (LN)

This Phase 2, multicenter, open-label study will evaluate the safety and efficacy of a single infusion of autologous anti-CD20/BCMA chimeric antigen receptor T cells (C-CAR168) following lymphodepleting chemotherapy in participants with refractory lupus nephritis who are not responding to standard therapy. Approximately 50 participants will undergo leukapheresis, lymphodepletion with fludarabine and cyclophosphamide, and infusion of C-CAR168. Participants will be followed for 104 weeks (approximately 2 years) to evaluate renal response, safety, CAR T-cell persistence, pharmacokinetics/pharmacodynamics, and biomarkers. Long-term safety follow-up for gene therapy-related events will continue for up to 15 years following CAR T-cell infusion.

The goal of this clinical trial is to evaluate the safety and preliminary efficacy of CD19 CAR-T cell therapy (TranspoCART19) in adults with refractory lupus nephritis. Lupus nephritis is a serious kidney complication of systemic lupus erythematosus that may not respond adequately to standard treatments. The main questions this study aims to answer are: * Is TranspoCART19 safe and tolerable in patients with refractory lupus nephritis? * Can TranspoCART19 induce complete or partial clinical and immunological remission? Participants will: * Undergo leukapheresis to collect immune cells for manufacturing TranspoCART19. * Receive lymphodepleting chemotherapy before treatment. * Receive a single fractionated infusion of TranspoCART19. * Attend regular follow-up visits for safety, disease activity, kidney function, immune response, and quality-of-life assessments for up to 24 months, with long-term safety follow-up after study completion.

A Phase 2 Study to Evaluate the Safety, Pharmacodynamics, Pharmacokinetics, and Clinical Activity of ADX-097 Administered Subcutaneously in Male and Female Participants Aged 16 Years or Older with Immunoglobulin A Nephropathy (IgAN), Lupus Nephritis (LN), or Complement Component 3 Glomerulopathy (C3G)

This is a single-center, single-arm, open-label phase 1/2 study of CART19 in children and young adults with refractory Systemic lupus erythematosus (SLE), including both patients diagnosed with lupus nephritis (LN) and patients with non-renal Systemic lupus erythematosus (SLE). Phase 1 will evaluate the safety of CART19 in 6-12 patients with Systemic lupus erythematosus (SLE). There is no planned dose escalation, but a dose de-escalation will be made based on the incidence of Dose Limiting Toxicities. Phase 2 will evaluate the efficacy and further evaluate the safety of CART19 in this population.

This Phase IIa, open-label, single-arm study includes an initial Safety Run-In followed by dose expansion to evaluate the safety, tolerability, cellular kinetics, pharmacodynamics, and preliminary clinical activity of a single infusion of ICG318 in participants with refractory SLE, with or without LN. Participants will receive protocol-specified lymphodepletion followed by ICG318 at the recommended Phase 2 dose.

This study is researching a particular group of experimental drugs administered for a short period in the treatment of participants with Lupus Nephritis (LN). The main aim of the current study is to see how safe and tolerable the study drugs are in a long-term follow-up. This is a main study, called an umbrella study, which includes several independent smaller sub-studies. Each of these smaller main sub-studies tests different drugs at the same time, all aimed at treating LN. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

To identify clinical and laboratory predictors of ICU admission and in-hospital mortality among hospitalized adults with lupus nephritis by evaluating the prognostic performance of NLR and CAR, comparing them with CRP and albumin using ROC analysis, determining optimal cutoff values, and identifying independent predictors through multivariable logistic regression

The purpose of this study is to evaluate an approach to managing patients with lupus nephritis called the Lupus Nephritis (LN) Pathway among approximately 25 patients. Activities include answering surveys and participating in an interview. Objectives include: 1) Assess feasibility and acceptability of the LN Care Pathway, 2) evaluate user experiences to identify opportunities for improvement, and 3) explore the preliminary effect of this pathway on medication adherence and clinical outcomes.

Lupus Nephritis is one of the most severe organ manifestations of systemic lupus erythematosus and represents a major cause of morbidity, chronic kidney disease, and long-term mortality. Despite significant advances in immunosuppressive therapies, a substantial proportion of patients fail to achieve sustained renal remission or progress to end-stage renal disease, highlighting the need for improved understanding of disease mechanisms and more reliable biomarkers for disease monitoring and therapeutic response

Systemic lupus erythematosus (SLE) is a chronic, multisystem autoimmune disease characterized by loss of immune tolerance, autoantibody production, immune complex deposition, and complement activation, resulting in widespread inflammation and organ damage. Renal involvement, known as lupus nephritis (LN), occurs in approximately 40-60% of SLE patients and represents one of the most severe disease manifestations, significantly contributing to morbidity and mortality.Lupus nephritis arises from immune complex deposition in glomerular and tubulointerstitial structures, causing inflammatory and proliferative lesions that can progress to chronic kidney disease or end-stage renal disease. The ISN/RPS classification provides a standardized histopathological framework essential for prognosis and guiding treatment decisions. In addition to renal complications, patients with SLE and LN are at substantially increased risk of premature cardiovascular disease, which cannot be fully explained by traditional cardiovascular risk factors.Persistent systemic inflammation, endothelial dysfunction, dyslipidemia, and insulin resistance accelerate atherosclerosis in these patients. Subclinical vascular changes, including increased carotid intima-media thickness (CIMT) and carotid plaque formation, often precede overt cardiovascular events, underscoring the importance of early cardiovascular risk assessment The triglyceride-glucose (TyG) index is a validated surrogate marker of insulin resistance, correlating with endothelial dysfunction, subclinical atherosclerosis, and increased CIMT Elevated TyG index may therefore serve as a simple, non-invasive tool for early cardiovascular risk stratification in patients with lupus nephritis

Childhood-onset systemic lupus erythematosus (cSLE) is a severe chronic autoimmune disease with a high burden of major-organ involvement. Lupus nephritis (LN) affects more than half of children with SLE, and proliferative LN-including class III, IV, III+V, and IV+V disease-is associated with acute kidney injury, progression to end-stage kidney disease, and poor long-term outcomes. Glucocorticoids remain a cornerstone of induction therapy for proliferative LN. However, the optimal initial dose in children is uncertain. Although recent adult SLE and LN guidelines increasingly recommend lower-dose glucocorticoid regimens with rapid tapering, pediatric guidelines still commonly recommend high initial prednisone doses of 1.5-2.0 mg/kg/day. Adult trials and comparative observational studies suggest that lower-dose glucocorticoid regimens may preserve efficacy while reducing treatment-related toxicity. Because cumulative glucocorticoid exposure in children may impair growth, development, psychosocial well-being, and medication adherence, this trial will compare low-dose versus high-dose initial glucocorticoid regimens for induction treatment of pediatric proliferative LN. The objective is to determine whether a lower-dose regimen is non-inferior in efficacy while reducing glucocorticoid-related adverse effects and improving quality of life.

Systemic lupus erythematosis (SLE) is a chronic, most probably auto-immune multisystem disease marked by relapsing-remitting course and the formation of a range of autoantibodies. SLE patients present with serious renal (lupus nephritis (LN)), cardiopulmonary, or nervous manifestation. LN occurs in 40%-70% of SLE cases during the first 10 years of disease and is marked by the presence of proteinuria (hallmark). A novel class of medications had been extracted from phlorizin and indicated for the treatment of type 2 diabetes (T2D), referred to as Sodium glucose cotransporter 2 (SGLT-2) inhibitors. They act by decreasing glucose reabsorption in the proximal renal tubules (SGLT2). Previous studies proved that SGLT2 inhibitors resulted in decreased postprandial hyperglycemia, enhanced glycemic control, reduced body weight and blood pressure, and albuminuria in those with T2D. Large placebo-controlled trials such as Empagliflozin-Kidney (EMPA-Kidney) and Dapagliflozin in Patients with Chronic Kidney Disease (DAPA-CKD) trial demonstrated the efficacy of empagliflozin and dapagliflozin, respectively, in patients with chronic kidney disease (CKD) regardless the diabetic cause of CKD, compared to placebo. EMPA-Kidney with median 2.0 years of follow-up reported that empagliflozin (EMPA) significantly (P\<0.001) lowered (13.1%) the risk of progression of kidney disease and death from cardiovascular causes than placebo (16.9%). Together with, DAPA-CKD trial reported that the risk of a composite of a sustained decline in the estimated GFR of at least 50% was significantly (P\<0.001) lower in the DAPA group (9.2%) compared to placebo group (14.5%) over a median of 2.4 years of follow-up. However, such studies excluded lupus nephritis population from clinical trials. Consequently, an experimental study is conducted to test the hypothesis that SGLT2 inhibitor EMPA is superior to placebo in improving proteinuria and estimated glomerular filtration rate (eGFR) in a group of patients with established LN already receiving the usual standard care and treatment. The trial participants compatabile with the elgibility criteria will be randomly assigned to two groups. One group will take Empagliflozin 25 mg tablet each day along with the standard care therapy. The other group will take a matching placebo besides the usual standard care therapy during the clinical trial period. Study outcomes will be measured three times, one before starting the medical study, the second and third will be 6 and 12 weeks after starting the clinical study, respectively. After that, the statistical siginficance of values between both groups will be reported to test the credibilty of the hypothesis. The study is primarily designed to evaluate the reno-protective effect of EMPA on kidney function, in terms of urinary protein-creatinine ratio (uPCR)and eGFR. Empagliflozin efficacy testing in lupus nephritis population (EMPA-LN) is a prospective, randomized, triple-blinded, parallel-group, placebo controlled phase 4 trial recruiting 66 subjects. A 10% drop-out rate is anticipated based on the clinical opinion of the care provider. The study will be conducted in accordance with the declaration of Helsinki. An ethical approval will be provided from an ethics committee.

Lupus nephritis is a chronic and life-threatening autoimmune cause of kidney disease that predominately impacts young people and can lead to kidney failure. Sodium-glucose co-transporter-2 inhibitors, including dapagliflozin, are known to improve outcomes for people with other causes of chronic kidney disease. This pilot and feasibility randomized clinical trial will test the use of dapagliflozin versus placebo in addition to standard of care treatment for patients with early and active lupus nephritis, a group who has not been included in past trials.

This is an investigator-initiated, open-label, single-arm, dose-escalation and dose-expansion study to evaluate the safety, tolerability, PK, PD, and preliminary efficacy of MTM-H-001 in adult participants with B-cell-related autoimmune diseases.

This study is a single-arm, single-center, open-label, dose-escalation exploratory clinical study designed to evaluate the safety, tolerability, and preliminary efficacy of CD19 CAR-γδ T cells. The subjects enrolled in this study are patients with relapsed/refractory autoimmune nephropathy, including lupus nephritis, IgA nephropathy, and membranous nephropathy. This study adopts a standard "3+3" design to assess the recommended dose (RD) and identify dose-limiting toxicities (DLTs). The treatment process is as follows: subjects who meet the inclusion criteria will receive lymphodepletion conditioning, followed by a single intravenous infusion of CD19 CAR-γδ T cells. The primary objective of this study is to evaluate the safety profile of this cellular therapy, including the incidence of DLTs, maximum tolerated dose (MTD) or RD, as well as the incidence and severity of treatment-related adverse events and clinically significant abnormal laboratory test results after CAR-γδ T cell infusion (including the incidence of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS)). The planned follow-up duration of this study is 1 years.

Approximately 30 participants will receive two intravenous doses of HB2198 and be followed for 12 months to assess safety, B cell depletion, disease activity, immunologic biomarkers, and renal outcomes.

1. Study Design This is a single-center, prospective, randomized, controlled, exploratory clinical trial. The study is designed to evaluate and compare the efficacy and safety of two biologic-based induction regimens against standard of care (SOC) and a triple-combination regimen in patients with active proliferative lupus nephritis (LN). 2. Study Objectives Primary Objective: To compare the 6-month complete renal response (CRR) rate among patients receiving biologic-based induction therapy, SOC induction therapy, and triple-combination induction therapy. Secondary Objectives: To compare the rates of partial renal response (PRR) and overall renal response (ORR) at monthly intervals up to Month 6; to assess the time to achieve CRR/PRR; to evaluate changes in clinical and immunological parameters from baseline; and to compare the safety profiles of the three treatment regimens. 3. Key Eligibility Criteria Patients aged 14-65 years with biopsy-proven active Class III or IV (±V) LN according to ISN/RPS 2018 classification, an SLE-DAI score \>6, and 24-hour urine protein \>1.0 g/d will be eligible. Key exclusion criteria include an eGFR ≥45 ml/min/1.73m², recent use of renal replacement therapy or potent immunosuppressive procedures, significant concurrent infections, severe hematological/ hepatic abnormalities, and known hypersensitivity to the study biologics. 4. Treatment Groups and Intervention Eligible patients will be randomized in a 2:2:1 ratio to one of three treatment arms for a 6-month induction period: Biologics Group (n≈20): Glucocorticoids + either Belimumab or Telitacicept. SOC Group (n≈20): Glucocorticoids + Mycophenolate Mofetil (MMF). Triple Therapy Group (n≈10): Glucocorticoids + MMF + either Belimumab or Telitacicept. The choice between Belimumab and Telitacicept within the Biologics and Triple Therapy groups will be determined jointly by the investigator and the patient. 5. Study Medications \& Administration Glucocorticoids: All patients will receive oral prednisone (or equivalent) starting at 0.5 mg/kg/day (max 40 mg/day), with a mandatory taper to ≤5 mg/day by Month 4 and stable dosing from Months 5-6. Intravenous methylprednisolone pulses are permitted per investigator discretion. Mycophenolate Mofetil (MMF): Administered only in the SOC and Triple Therapy groups. The target dose is 1.5-2.0 g/day, maintained until the end of the treatment period. Belimumab: Administered via intravenous infusion at 10 mg/kg (600 mg/dose) every 2 weeks. Telitacicept: Administered via subcutaneous injection at 160 mg once weekly. Patients in the Biologics or SOC groups showing no response by Month 3 may directly switch to the Triple Therapy regimen. 6. Primary Efficacy Endpoint The primary endpoint is the proportion of patients achieving Complete Renal Response (CRR) at Month 6. CRR is strictly defined as: 24-hour urine protein \<0.5 g/d, AND Estimated Glomerular Filtration Rate (eGFR) ≥85% of the baseline value, AND No requirement for rescue therapy or premature treatment withdrawal. 7. Secondary Efficacy \& Safety Assessments Key secondary efficacy assessments include monthly CRR, PRR, and ORR rates; time to response; incidence of renal-related events; and changes in proteinuria, eGFR, serum creatinine, and disease activity scores (SELENA-SLEDAI, BILAG-2004, PGA). Safety will be evaluated through the incidence and severity of adverse events, with special attention to infections, infusion/injection reactions, and metabolic parameters. 8\. Statistical Considerations This is an exploratory study with a planned enrollment of 40-50 patients. The primary analysis will use the Full Analysis Set (FAS) under the intention-to-treat principle. The difference in the Month 6 CRR rate among the three groups will be analyzed using the Chi-square test. Time-to-event data will be analyzed using the Kaplan-Meier method with Log-rank test for comparisons. 9\. Hypothesis: This study protocol outlines a head-to-head comparison of novel biologic-based induction strategies against current SOC for active LN. It aims to generate critical preliminary data on whether glucocorticoids combined with a biologic (Belimumab or Telitacicept) alone can induce effective renal remission, potentially offering a targeted treatment option with a different safety profile compared to conventional immunosuppressive therapy. The results may inform the design of larger, confirmatory trials in LN management.
