JOENJA vs MAYZENT
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 on lymphocytes, blocking egress from lymph nodes, reducing circulating lymphocytes.
JOENJA (lenalidomide) 2.5 mg orally once daily on days 1-21 of a 28-day cycle.
0.25 mg orally once daily initially, titrated over several weeks to a maintenance dose of 2 mg orally once daily.

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 8–10 days due to slow dissociation from sphingosine 1-phosphate receptors; steady-state reached in 3–4 weeks.
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 (≈76% as metabolites) and renal (≈24% as metabolites and minor unchanged drug).
