OBJECTIVE: This study assessed the impact of varying lenvatinib crystalline forms in 10-mg lenvatinib capsules on drug bioavailability in healthy volunteers.
MATERIALS: Lenvatinib 10-mg capsules (low C and high C forms).
METHODS: This randomized, three-period- crossover study compared the pharmacokinetics and safety of two crystalline forms of capsules (low C-form, <4% crystalline; high C-form, 38% crystalline) to a standard (ref Cform, 15% crystalline).
RESULTS: 59 subjects were evaluable for pharmacokinetics. Test/reference ratios of the geometric least squares means (LSM) and 90% confidence intervals (CI) for AUC0-t (t up to 120 hours), AUC0-∞, and Cmax for low C-form vs. ref C-form were 101 (94.8, 107), 101 (95.3, 107), and 98.7 (88.6, 110), respectively; and for high C-form vs. ref C-form were 96.0 (92.1, 100), 96.5 (92.5, 101), and 90.6 (83.5, 98.4), respectively. The incidence of treatment-emergent adverse events (TEAE) and treatment-related adverse events (TRAE) were comparable between all formulations (TEAE range 20-24%; TRAE range 15-19%). One serious TRAE (spontaneous abortion) occurred in the low C-form group.
CONCLUSIONS: For both comparisons, the 90% CIs of the test/reference ratios were within the regulatory acceptance range (80-125%), suggesting that both test formulations (low Cform and high C-form) were bioequivalent to the reference formulation for Cmax, AUC0-t, and AUC0-∞.
