Jade Biosciences announced that the first participant has been dosed in Juniper, the Company's Phase 2 trial evaluating JADE101 in participants with immunoglobulin A nephropathy. JADE101 is designed with high binding affinity to selectively block APRIL, a key driver of pathogenic IgA production in IgAN, a chronic autoimmune disease that frequently affects young adults and can lead to end-stage kidney disease over a patient's lifetime. Interim data from JUNIPER are expected in 2027.

About JBIO
Jade Biosciences, Inc. is a biotechnology company, which is focused on developing therapies for autoimmune diseases. The Company’s lead asset, JADE-001, is an investigational anti-A PRoliferation-Inducing Ligand (APRIL) monoclonal antibody for the treatment of Immunoglobulin A (IgA) nephropathy (IgAN), an autoimmune condition in which the kidney is damaged by pathogenic IgA containing immune complexes, leading to proteinuria and kidney function decline, and potentially progressing to end-stage kidney disease requiring dialysis or transplantation. Designed to block the APRIL protein, JADE-001 targets an underlying cause of IgAN, offering the potential to reduce pathogenic IgA levels, decrease proteinuria, and preserve kidney function over the long term. The Company’s pipeline also includes two undisclosed antibody discovery programs: JADE-002 and JADE-003, which are in preclinical development.
