Medical Director; Nephrology

Medical Director (Nephrology) – Jade Biosciences

Jade Biosciences is focused on developing innovative, best‑in‑class therapies to address critical unmet needs in autoimmune diseases. Our lead candidate, JADE
101, is designed to inhibit the cytokine APRIL (A Proliferation‑Inducing Ligand) and is being developed for the treatment of immunoglobulin A nephropathy (IgAN), a chronic kidney disease that can impair kidney function over time. JADE
101 aims to reduce harmful IgA antibodies, lower proteinuria (a key marker of kidney damage), and preserve long‑term kidney function. A Phase 1 healthy‑volunteer study of JADE
101 is ongoing, with interim, biomarker‑rich data expected in the first half of 2026. Jade’s pipeline also includes a second development candidate, JADE
201, and an undisclosed antibody discovery program, JADE‑003, both currently in preclinical development. Visit  and follow us on Linked In for more information.
