Clinical trials

This randomized, double-blind, parallel-group, noninferiority clinical trial will evaluate the efficacy and safety of ivarmacitinib compared with oral prednisone in participants with mild-to-moderate active systemic lupus erythematosus (SLE) without active major organ involvement. Approximately 294 participants will be randomized in a 1:1 ratio to receive either ivarmacitinib 8 mg once daily or oral prednisone starting at 30 mg/day with a prespecified tapering schedule, together with the corresponding matching placebo, for 24 weeks. The study will assess whether ivarmacitinib is noninferior to oral prednisone in achieving the primary efficacy outcome. The primary outcome is the proportion of participants achieving remission of arthritis and/or rash, as defined by the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), at Week 12. Safety and secondary efficacy outcomes will be evaluated throughout the 24-week treatment period.

This is a 52-week, multicenter, prospective, open-label, randomized controlled clinical study, comparing the efficacy and safety of tocilizumab, rituximab, and csDMARD methotrexate in patients with RA-ILD.

The goal of this clinical trial is to learn if sirolimus, added to standard background therapy (corticosteroids and hydroxychloroquine), works to treat systemic lupus erythematosus-associated immune thrombocytopenia (SLE-ITP) in adults aged 18 to 65 years. The study also aims to evaluate the long-term effectiveness and safety of sirolimus over 48 weeks. The main questions it aims to answer are: 1. Does sirolimus increase the overall response rate (complete or partial remission of thrombocytopenia) at 24 weeks compared with placebo? 2. The safety issues when taking sirolimus over 24 weeks (Phase 1) and up to 48 weeks (Phase 2). 3. How long does the treatment effect last, and what is the relapse rate during open-label extension? In Phase 1 (first 24 weeks), researchers will compare sirolimus to a placebo (an identical-looking capsule containing no active drug) to see if sirolimus works to treat SLE-ITP when both groups also receive standardized prednisone and hydroxychloroquine. In Phase 2 (weeks 24 to 48), all participants will receive open-label sirolimus to assess long-term efficacy and safety. Participants will: 1. Phase 1: Take sirolimus (1.5 mg once daily) or a placebo for 24 weeks, plus standardized prednisone (tapered according to protocol) and hydroxychloroquine (0.4 g daily) 2. Phase 2: After completing Phase 1, take open-label sirolimus (1.5 mg once daily) for an additional 24 weeks, continuing stable or tapering doses of prednisone and hydroxychloroquine 3. Visit the clinic at screening, baseline, weeks 4, 12, 24 (end of Phase 1), and then at weeks 28, 36, and 48 (end of Phase 2) for checkups, blood tests, and disease activity assessments 4. Receive telephone follow-ups at weeks 8, 16, 20, 32, 40, and 44 to report platelet counts, medication adherence, and adverse events

This is a prospective, open-label, controlled, multiple centers, randonmized clinical trial. It compares the clinical efficacy and safety of vunakizumab ivarmacitinib and glucocorticoids in the treatment of active Takayasu's arteritis.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by heterogeneous clinical manifestations ranging from mild cutaneous involvement to severe multi-organ damage. While its pathogenesis involves complex cytokine dysregulation, emerging evidence implicates IL-17 as a potential contributor. Elevated serum IL-17 levels have been observed in SLE patients compared to healthy controls, with heightened expression detected in renal and cutaneous lesions. Ustekinumab, a monoclonal antibody targeting IL-23/IL-12 that indirectly modulates IL-17 signaling, demonstrated superior efficacy and safety to placebo in an SLE clinical trial, particularly in glucocorticoid dose reduction. Notably, no clinical trials have directly evaluated IL-17-targeted therapies for SLE, though case reports suggest secukinumab (an anti-IL-17A agent) may improve cutaneous manifestations in psoriasis-SLE overlap patients. Vunakizumab, a humanized anti-IL-17A monoclonal antibody (IgG1/κ) with a unique epitope-binding profile, selectively inhibits IL-17A-mediated inflammatory signaling. Its established safety profile and infrequent dosing regimen in IL-17-mediated diseases (e.g., psoriasis, psoriatic arthritis) warrant investigation in SLE. The investigators aim to provide new treatment options for SLE patients

This is a 24-week, single-center, randomized, open-label trial conducted by Peking Union Medical College Hospital. The aim of this study is to assess the efficacy and safety of deucravacitinib in adult patients with relapsing TAK in comparison to patients treated with TNF inhibitor (TNFi), the most well-recognized therapeutic choice of non-glucocorticoid immunosuppressive for patients with relapsed or refractory TAK.

This is a single-center, single-arm, open-label, prospective study on the efficacy and safety of Telitacicept in patients with refractory rheumatoid arthritis.

Early prediction of major organ damage in SLE needs to dynamically track the evolution of SLE patients before and after the onset of major organ damage, and analyze the microscopic molecular evolution patterns synchronized with the macroscopic pathophysiological changes.

The goal of this clinical trial is to determine whether mycophenolate mofetil(MMF) combined with tacrolimus(TAC) can maintain remission in patients with lupus nephritis (LN) who have reached treatment targets after steroid tapering. The main question\[s\] it aims to answer are: * The efficacy, safety and tolerability of MMF combined with TAC regimen in the treatment of LN patients in the maintenance period. * The influence of low-dose steroid on carotid intima thickness (CIMT). * The omics and cell-free RNA (cfRNA) spectral differences related to lupus flare. * The differences in health economics between steroid tapering and steroid maintenance patients. Participants will be randomly assigned into 2 groups. In the steroid tapering group, participants will take MMF+TAC treatment without steroid for 1 year, and participants who stop steroid treatment without lupus flare will be randomly assigned to monotherapy with MMF or TAC. In the steroid maintenance group, participants will take MMF+TAC+steroid for 1 year, and participants without lupus flare will stop the use of steroid for 6 months. Participants without lupus flare after the stop of steroid will be randomly assigned to monotherapy with MMF or TAC.

This is an observational study of patients with lupus nephritis aiming to find biomarkers that can predict patients' response to immunosuppressants. We planed to collect 100 lupus nephritis patients' peripheral blood,kidney tissues and urine before and after treatment (mycophenolate mofetil or cyclophosphamide, in combination with glucocorticoids). Then multi omics analysis, including single cell RNA-seq, ATAC-seq and CITE-seq, will be performed to find new biomarkers for patients' response and prognosis.

This study is a prospective, open-labelled, randomized, controlled, single-center clinical trial. The aim of this study is to compare the remission rate of patients treated with Telitacicept combined with azathioprine and azathioprine alone in remission-maintenance treatment of AAV.

This study is a prospective, open-labelled, randomized, controlled, single-center clinical trial. The aim of this study is to investigate the remission rate of patients treated with Telitacicept combined with Rituximab in remission-induction and Telitacicept alone in remission-maintain treatment.
