Jade Biosciences Inc., a biotechnology company specializing in therapies for autoimmune diseases, announced plans to initiate a clinical study of its anti-APRIL monoclonal antibody, JADE101, in healthy volunteers in the latter half of 2025. This study will assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and biomarker suppression of JADE101, specifically targeting APRIL and IgA. Interim results from this study are expected in the first half of 2026, which will aid in determining appropriate dosing for future studies in patients with IgA nephropathy (IgAN). Preclinical data, presented at the 62nd European Renal Association Congress, highlighted JADE101's potential for best-in-class efficacy with convenient dosing intervals. A conference call and webcast regarding these developments were held on June 9, 2025.
