Pharmacokinetic Study of E7080/Lenvatinib in Chinese Patients With Unresectable Hepatocellular Carcinoma (HCC)

The primary purpose of this study is to assess the single- and multiple-dose pharmacokinetic (PK) profile of lenvatinib in Chinese participants with unresectable Hepatocellular Carcinoma (HCC).

   1. Absolute neutrophil count (ANC) ≥ 1.5 × 10\^9/Liter (L)
   2. Hemoglobin (Hb) ≥ 8.5 gram per deciliter (g/dL)
   3. Platelet count ≥ 75 × 10\^9/L
4. Adequate liver function, defined as:

   1. Albumin ≥ 2.8 g/dL
   2. Bilirubin ≤ 3.0 milligram per deciliter (mg/dL)
   3. Aspartate aminotransferase (AST), alkaline phosphatase (ALP), and alanine aminotransferase (ALT) ≤ 5 × the upper limit of normal (ULN)
5. Adequate blood coagulation function, defined as international normalized ratio (INR) ≤ 2.3
6. Adequate renal function defined as creatinine clearance \> 40 milliliter per min (mL/min) calculated per the Cockcroft-Gault formula
7. Adequately controlled blood pressure (BP) with up to 3 antihypertensive agents, defined as systolic BP ≤ 150 millimeter of mercury (mm Hg) and diastolic BP ≤ 90 mm Hg at screening and no change in antihypertensive therapy within 1 week prior to the registration.
8. Child-Pugh A (score 5-6)
9. Eastern Cooperative Oncology Group (ECOG)- performance status (PS) 0 or 1
10. Survival expectation of 12 weeks or longer after starting study drug
11. Males or females aged at least 18 years at the time of informed consent.
12. Females must not be lactating or pregnant at Screening or Baseline (as documented by a negative beta-human chorionic gonadotropin \[Beta-hCG\] test with a minimum sensitivity of 25 International Unit/Liter \[IU/L\] or equivalent units of beta-hCG). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.
13. All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group and without other known or suspected cause) or have been sterilized surgically (ie, bilateral tubal ligation, total hysterectomy or bilateral oophorectomy, all with surgery at least one month before dosing).
14. Females of childbearing potential must not have had unprotected sexual intercourse within 30 days before study entry and must agree to use a highly effective method of contraception (eg, total abstinence, an intrauterine device, a double-barrier method \[such as condom plus diaphragm with spermicide\], a contraceptive implant, an oral contraceptive, or have a vasectomized partner with confirmed azoospermia) throughout the entire study period and for 30 days after study drug discontinuation. If currently abstinent, the participant must agree to use a double barrier method as described above if she becomes sexually active during the study period or for 30 days after study drug discontinuation. Females who are using hormonal contraceptives must have been on a stable dose of the same hormonal contraceptive product for at least 4 weeks before dosing and must continue to use the same contraceptive during the study and for 30 days after study drug discontinuation.
15. Male participants must have had a successful vasectomy (confirmed azoospermia) or they and their female partners must meet the criteria above (ie, not of childbearing potential or practicing highly effective contraception throughout the study period and for 30 days after study drug discontinuation). No sperm donation is allowed during the study period and for 30 days after study drug discontinuation.
16. Provide written informed consent
17. Willing and able to comply with all aspects of the protocol as judged by the Investigator.

Exclusion Criteria

1. Imaging findings for HCC corresponding to any of the following:

   1. HCC with ≥50% liver occupation
   2. Clear invasion into the bile duct
   3. Portal vein invasion at the main portal branch (Vp4)
2. Participants who have received lenvatinib
3. Participants who have received any anti-cancer therapy (including surgery, percutaneous ethanol injection, radio frequency ablation, transarterial \[chemo\] embolization, hepatic intra-arterial chemotherapy, biological, immunotherapy, hormonal, any investigational drugs or radiotherapy) or any blood enhancing treatment (including blood transfusion, blood products, or agents that stimulate blood cell production, eg, granulocyte colony-stimulating factor \[G-CSF\]) within 28 days prior to registration.
4. Participants who have not recovered from toxicities as a result of prior anticancer therapy except alopecia and infertility. Recovery is defined as \< Grade 2 severity per Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE v4.0).
5. Significant cardiovascular impairment: history of congestive heart failure greater than New York Heart association (NYHA) Class II, unstable angina, myocardial infarction or stroke within 6 months of the first dose of study drug, or cardiac arrhythmia requiring medical treatment at screening
6. Prolongation of Q wave and T wave interval corrected by the Fridericia formula (QTcF) interval to \> 480 milli second (msec)
7. Gastrointestinal malabsorption, or any other condition in the opinion of the investigator that might affect the absorption of lenvatinib
8. Bleeding or thrombotic disorders or use of anticoagulants requiring therapeutic INR monitoring, eg, warfarin or similar agents. Treatment with low molecular weight heparin and factor X inhibitors which do not require INR monitoring is permitted. Antiplatelet agents are prohibited throughout the study.
9. Gastrointestinal bleeding event within 28 days prior to registration
10. Gastric or esophageal varices that require interventional treatment within 28 days prior to randomization. Prophylaxis with pharmacologic therapy (eg, nonselective beta-blocker) is permitted.
11. Active hemoptysis (bright red blood of at least 0.5 teaspoon) within 28 days prior to registration
12. Active malignancy (except for HCC or definitively treated melanoma in-situ, basal or squamous cell carcinoma of the skin, or carcinoma in-situ of the cervix) within the past 36 months from registration.
13. Any history of or current brain or subdural metastases
14. Participants having \> 1+ proteinuria on urine dipstick testing will undergo 24h urine collection for quantitative assessment of proteinuria. Participants with urine protein ≥ 1 gram (g)/24 hour (h) will be ineligible.

16. Any medical or other condition that in the opinion of the investigator would preclude participation in a clinical study
17. Human immunodeficiency virus (HIV) positive, or active infection requiring treatment (except for hepatitis virus)
