About JADE101

JADE101 is an investigational anti-APRIL (A Proliferation-Inducing Ligand) monoclonal antibody being developed for the treatment of IgA nephropathy (IgAN), a chronic autoimmune kidney disease characterized by the deposition of pathogenic IgA-containing immune complexes in the kidneys. These deposits can lead to proteinuria, declining kidney function, and potentially end-stage kidney disease requiring dialysis or transplantation. By targeting APRIL, a protein involved in the overproduction of IgA, JADE101 aims to reduce the levels of disease-driving IgA, decrease proteinuria, and preserve kidney function. Engineered with half-life extension technology, JADE101 is designed for dosing at intervals of at least eight weeks, offering the potential for durable clinical activity and improved patient convenience, particularly important for a condition often diagnosed in young adulthood and potentially requiring life-long treatment.
