BACKGROUND AND OBJECTIVES Lenvatinib is an oral, multitargeted tyrosine kinase inhibitor under clinical investigation in solid tumours. This study evaluated the influence of P-glycoprotein (P-gp) inhibition (single-dose rifampicin) and simultaneous cytochrome P450 3A4 (CYP3A4)/P-gp induction (multiple-dose rifampicin) on lenvatinib pharmacokinetics.

PURPOSE Felbamate (FBM) pharmacokinetic parameters, safety and tolerability in the dose range of 1,200-6,000 mg/day were assessed in two open-label studies with similar designs. METHODS In study A, newly diagnosed subjects with epilepsy receiving FBM monotherapy at a starting dose of 1,200 mg/day (400 mg/three times daily, t.i.d.) and increased 1,200(More)
OBJECTIVE To evaluate the effect of formulation and a high-fat meal on the pharmacokinetics of orally administered lenvatinib (E7080). MATERIALS Lenvatinib 10-mg capsule and tablet. METHODS Pharmacokinetics and safety of a single 10-mg lenvatinib dose were evaluated in healthy subjects in two randomized, two-period, crossover, phase 1, bioavailability(More)
PURPOSE This "3+3" phase I study evaluated the safety, biologic, and clinical activity of lenvatinib, an oral multikinase inhibitor, in patients with solid tumors. EXPERIMENTAL DESIGN Ascending doses of lenvatinib were administered per os twice daily in 28-day cycles. Safety and response were assessed for all patients. Angiogenic and apoptotic factors(More)
This open-label, single-dose study assessed lenvatinib pharmacokinetics (PK) in subjects with normal hepatic function (n = 8) and mild, moderate, or severe hepatic impairment (n = 6 each). Subjects received 10 mg oral lenvatinib, except those with severe hepatic impairment (5 mg). Plasma and urine samples were collected over 14 days; free and total(More)
Lenvatinib is an orally available multi-targeted tyrosine kinase inhibitor with anti-angiogenic and antitumor activity. To get more insight into the disposition of lenvatinib, a mass balance study was performed in patients with advanced solid tumors. A single oral 24 mg (100 μCi) dose of (14)C-lenvatinib was administered to six patients, followed by(More)
Background: Lenvatinib is an oral, multitargeted, tyrosine kinase inhibitor under clinical investigation in solid tumors. In vitro evidence indicates that lenvatinib metabolism may be modulated by ketoconazole, an inhibitor of CYP3A4 and p‐glycoprotein. (18–55 years; N ¼ 18) were randomized to one of two sequences (ketoconazole ! placebo or vice versa).(More)
Lenvatinib is an oral, multiple receptor tyrosine kinase inhibitor. Preclinical drug metabolism studies showed unique metabolic pathways for lenvatinib in monkeys and rats. A human mass balance study demonstrated that lenvatinib related material is mainly excreted via feces with a small fraction as unchanged parent drug, but little is reported about its(More)
AIMS Lenvatinib was recently approved for the treatment of radioiodine-refractory differentiated thyroid cancer (RR-DTC). Here, we characterized the pharmacokinetic (PK) profile of lenvatinib and identified intrinsic and extrinsic factors that explain interindividual PK variability in humans. METHODS This population PK analysis used pooled data from 15(More)
PURPOSE QT assessment of oncology drugs is generally challenging because they are genotoxic and, of necessity,they require multisite evaluation in cancer patients. Lenvatinib is not genotoxic, therefore, this thorough QT (TQT)study with lenvatinib, a multityrosine kinase inhibitor, was undertaken utilizing healthy volunteers and concentration effect(More)
