Vunakizumab for the Treatment of Mild to Moderate Systemic Lupus Erythematosus

Pilot Study on the Treatment of Vunakizumab in Mild to Moderate Systemic Lupus Erythematosus

About This Trial

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
