ICLUSIG vs NERLYNX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ponatinib is a multi-targeted tyrosine kinase inhibitor that inhibits BCR-ABL, including T315I mutant form, and also inhibits VEGFR, PDGFR, FGFR, EPH receptors, and SRC family kinases.
Neratinib is an irreversible pan-ErbB receptor tyrosine kinase inhibitor that inhibits EGFR, HER2, and HER4, leading to reduced downstream signaling and cell proliferation.
45 mg orally once daily with or without food.
NERLYNX (neratinib) 240 mg (6 tablets of 40 mg) orally once daily with food for a total duration of 1 year.

Terminal elimination half-life is approximately 7.5 hours in healthy subjects, supporting twice-daily dosing.
Terminal half-life approximately 7–17 days (mean ~9 days) after a 240 mg daily dose, supporting once-daily dosing. Steady state reached by ~4–6 weeks.
Primarily fecal (91%) as unchanged drug and metabolites; renal elimination accounts for less than 4% of the dose.
Primarily hepatic metabolism; 97% of dose recovered in feces (including unchanged drug and metabolites), <1% in urine as unchanged drug. Biliary excretion is a major route.
