LITFULO vs VIVJOA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Litfulo (ritlecitinib) is a Janus kinase (JAK) inhibitor that selectively inhibits JAK3 and to a lesser extent TEC family kinases, thereby modulating the signaling pathways involved in the immune response.
VIVJOA (fosmanogepix) is a first-in-class antifungal agent that inhibits the fungal enzyme Gwt1, which is involved in glycosylphosphatidylinositol (GPI) anchor biosynthesis. This disrupts cell wall integrity and fungal growth.
50 mg orally once daily, with or without food.
VIVJOA (750 mg tablet) is administered as a single oral dose of 750 mg, taken once daily for 6 weeks.

Terminal elimination half-life is approximately 50 hours (range 40–60 h), supporting once-daily or twice-daily dosing with steady-state achieved within 10–14 days.
Terminal elimination half-life is approximately 20–26 hours, supporting once-daily dosing for sustained therapeutic levels.
Primarily excreted unchanged in feces (≈66%) via biliary secretion, with renal excretion accounting for ≈23% as unchanged drug and metabolites; <1% excreted in urine as unchanged parent compound.
Primarily hepatic metabolism via CYP3A4, with <1% excreted unchanged in urine; fecal elimination accounts for approximately 88% of the administered dose as metabolites.
