Sjogren's Syndrome (SS)

This is the first-in-human trial of MTS109 (mRNA-LNP). The goal of this clinical trial is to evaluate the safety, tolerability of intravenous injection of MTS109 in moderate to severe autoimmune diseases.

This study evaluates the safety and efficacy of YTS109 cells in adults with relapsed/refractory autoimmune diseases, such as Systemic Lupus Erythematosus (SLE), including LN and SLE-ITP, Sjogren's Syndrome, etc. Aproximately 18 patients aged 18-65 will receive a single infusion of YTS109 cells. The dose groups are set to commence at 3×10⁶ STAR -T cells/kg, employing a 3+3 escalation principle for dose titration. The primary objective of this study is to evaluate the safety of YTS109 cells therapy in treating recurrent/refractory autoimmune diseases, while the secondary objectives are to assess the efficacy of YTS109 cells as well as their pharmacokinetic and pharmacodynamic characteristics. The primary endpoint is observations of types, severity, and frequency of adverse events (AEs) and efficacy assessment. This single-arm, open-label trial will enroll patients across The First Affiliated Hospital of Anhui Medical University.

This exploratory, single-arm, open-label study will evaluate the safety and preliminary efficacy of YTS109 cell therapy in pediatric patients with relapsed/refractory autoimmune diseases, including systemic lupus erythematosus, diffuse systemic sclerosis, idiopathic inflammatory myopathies, and Sjögren's syndrome, as well as other eligible autoimmune diseases defined by the protocol eligibility criteria. Approximately 12 patients aged 5 to \<18 years will be enrolled at Children's Hospital of Fudan University and will receive a single intravenous infusion of YTS109 cells. Dose escalation will follow a standard 3+3 design starting at 1.5 × 10\^6 cells/kg. The primary objective is to assess the safety and preliminary efficacy of YTS109 cell therapy in this population. Secondary objectives include characterizing the pharmacokinetic and pharmacodynamic profiles of YTS109 cells. Primary endpoints include the type, severity, and frequency of adverse events, along with efficacy assessments.

This is an open-label, dose escalation study in patients with relapsed and refractory autoimmune diseases. Study drug, TI-0032-III injection, is composed of lipid nanoparticles (LNPs) targeting T cells that encapsulate circular RNA encoding the CD19 chimeric antigen receptor (CAR), which is a therapeutic biological product. It is clinically intended for the treatment of various relapsed and refractory B cell-related autoimmune diseases, such as systemic lupus erythematosus, sjögren's syndrome, systemic sclerosis, idiopathic inflammatory myositis, and antiphospholipid syndrome.
