Nephritis is one of the major complications of systemic lupus erythematosus (SLE). While glucocorticoids (GC) are frequently used as the first line treatment for lupus nephritis, long-term GC usage is often complicated by severe adverse effects. To address this challenge, we have developed a polyethylene glycol (PEG)-based macromolecular prodrug (ZSJ-0228) of dexamethasone, which self-assembles into micelles in aqueous media. When compared to the dose equivalent daily dexamethasone 21-phosphate disodium (Dex) treatment, monthly intravenous administration of ZSJ-0228 for two months significantly improved the survival of lupus-prone NZB/W F1 mice and was much more effective in normalizing proteinuria, with clear histological evidence …
