JOENJA vs ZEPOSIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
JOENJA (lenvatinib) is a tyrosine kinase inhibitor that inhibits multiple receptor tyrosine kinases including VEGFR1-3, FGFR1-4, PDGFRα, RET, and KIT. It blocks tumor angiogenesis and proliferation.
Sphingosine 1-phosphate receptor modulator; binds with high affinity to S1P receptors 1 and 5, blocking lymphocyte egress from lymph nodes, reducing circulating lymphocytes.
JOENJA (lenalidomide) 2.5 mg orally once daily on days 1-21 of a 28-day cycle.
0.92 mg orally once daily with or without food.

Terminal elimination half-life is approximately 12-15 hours in patients with normal renal function. This supports once-daily dosing in most indications. Half-life is prolonged in renal impairment, requiring dose adjustment.
Terminal elimination half-life is approximately 21 hours (range 14–30 hours) in healthy subjects, supporting once-daily dosing without need for loading dose.
Primarily renal excretion of unchanged drug (approximately 70-80% of the dose). A small fraction (5-10%) is eliminated via feces via biliary excretion. The remainder is metabolized and excreted as inactive metabolites.
Primarily fecal (approximately 78% of dose) via biliary excretion of unchanged drug and oxidative metabolites; renal excretion accounts for approximately 15% of dose, with <1% excreted unchanged in urine.
