Jade Biosciences, Inc. JBIO

We are a clinical-stage biopharmaceutical company developing novel biologic therapies for patients living with autoimmune diseases. Our goal is to improve meaningfully upon the existing treatment paradigm through the delivery of improved dosing and convenience, a comparable safety profile, and potentially increased clinical activity. Our approach is to discover and efficiently develop biologics that address emerging targets supported by third-party clinical data and that overcome shortcomings of existing product candidates in development, such as potency, bioavailability, formulation, and pharmacokinetic properties.

Our lead product candidate, JADE101, is a monoclonal antibody ("mAb") targeting a cytokine called "A PRoliferation Inducing Ligand" ("APRIL") that modulates plasma cell survival and immunoglobulin production, which we plan to initially develop for the treatment of IgA nephropathy ("IgAN"). Our second product candidate is JADE201, a mAb targeting B cell activating factor receptor ("BAFF-R") for the treatment of multiple autoimmune disorders. Our third product candidate is JADE301, a mAb targeting an undisclosed pathway.
