16. Psychotic disorder(s) or unstable recurrent affective disorder(s) evident by use of antipsychotics or prior suicide attempt(s) within approximately the last 2 years.

17. History of drug or alcohol dependency or abuse within approximately the last 2 years.

18. Presence of a progressive central nervous system (CNS) disease, including degenerative CNS diseases and progressive tumors.

19. Pulmonary lymphangitic involvement that results in pulmonary dysfunction requiring active treatment, including the use of oxygen.

20. Use of illegal recreational drugs.

21. Any medical or other condition that, in the opinion of the investigator, would preclude the subject's participation in a study.

Intervention

Drug:
• E7820
FOOD EFFECT STUDY: Each subject (a minimum of 12 subjects) will be assigned according to a randomization code to receive a single 50 mg dose of E7820 on Day 1, either after fasting for 10 hours, or immediately after consuming a high fat breakfast. Following a 7-day washout period, the subjects will crossover and a second 50 mg dose of E7820 will be administered on Day 8.
• E7820
MTD DETERMINATION FOR BID DOSING SCHEDULE The initial dose of E7820 will be 50 mg BID. If allowed by the rules for dose escalation, the dose escalations will be to 60 mg BID, 80 mg BID, and 100 mg BID.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Treatment Phase Part A: AUC(0-inf): Area Under the Plasma Concentration-time Curve From Time 0 to Infinity for E7820		Day 1 or 8: 0.5-48 hours
Primary	Treatment Phase Part A: AUC(0-t): Area Under the Plasma Concentration- Time Curve From Time 0 to t for E7820		Day 1 or 8: 0.5-48 hours
Primary	Treatment Phase Part A: Cmax: Maximum Observed Plasma Concentration for E7820		Day 1 or 8: 0.5-48 hours
Primary	Treatment Phase Part B: Maximum Tolerated Dose (MTD) of E7820 BID Dosing Schedule	MTD defined as the highest dose level at which no more than 1 of 6 participants experienced a dose-limiting toxicity(DLT), with the next higher dose having at least 2 of 3 or 2 of 6 participants experiencing DLTs. DLTs were defined using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events(CTCAE) Version 4.03 as: Neutropenia less than(<) 0.5*10^9/liter(L) for greater than(>) 5 days; neutropenia <1*10^9/L with fever; thrombocytopenia <25*10^9/L accompanied by bleeding or thrombocytopenia <10*10^9/L; any Grade 3 or 4 nonhematological toxicity for which the study drug could not be excluded as a cause (other than nausea, vomiting or diarrhea in the absence of appropriate prophylaxis) with the following clarification: Grade 3 or 4 nonhematological laboratory abnormalities for which there was no expected clinical correlation would not be considered DLTs; treatment delay of >14 days required to recover from E7820-related toxicities.	Up to Cycle 6 (Cycle length =28 days)
Secondary	Extension Phase Part A, and Treatment and Extension Phase Part B: Number of Participants With Best Overall Response (BOR)	BOR based on RECIST 1.1 for target and non-target lesions is complete response (CR) or partial response (PR) for >4 weeks or stable disease (SD) for >5 weeks from first dose. CR: disappearance of target and non-target lesions, normalization of tumor marker level, all lymph nodes must be non- pathological in size (<10 millimeter [mm] short axis). PR: at least 30% decrease in sum of diameters (SOD) of target lesions, taking as reference the baseline SOD persistence of one or more non- target lesions and/or maintenance of tumor marker level above the normal limits. SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest SOD. PD: at least 20% increase (including an absolute increase of at least 5 mm) in the SOD of target lesions, taking as reference the smallest sum and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions.	From first dose of study drug (Baseline) up to approximately 6.6 years
Secondary	Extension Phase Part A, and Treatment and Extension Phase Part B: Duration of Response	Duration of response based on RECIST 1.1 for target and non-target lesions is the time from the date of first documented confirmed CR/PR until the first documentation of confirmed progressive disease (PD) or death, whichever came first. CR: disappearance of target and non-target lesions,normalization of tumor marker level,all lymph nodes must be non-pathological in size(<10 mm short axis). PR: at least 30% decrease in SOD of target lesions,taking as reference the baseline SOD persistence of one or more non- target lesions and/or maintenance of tumor marker level above the normal limits. PD:at least 20% increase (including an absolute increase of at least 5 mm) in the SOD of target lesions,taking as reference the smallest sum and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions.	From date of first documented confirmed CR/PR until date of first documentation of PD or death (approximately up to 6.6 years)
Secondary	Extension Phase Part A, and Treatment and Extension Phase Part B: Number of Participants With Death and Progressive Disease (PD)	PD: at least 20% increase (including an absolute increase of at least 5 mm) in the SOD of target lesions. For PD: participants with best response of PD have been reported. For Death: participants with death known to have died at any point have been reported.	From first dose date to the date of the first documentation of confirmed PD or death (approximately up to 6.6 years)
Secondary	Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)	Safety assessments consisted of monitoring and recording all AEs and SAEs; regular monitoring of hematology, clinical chemistry, and urine values; physical examinations; and regular measurement of vital signs, ECG, and multiple-gated acquisition (MUGA) scans or echocardiograms.	From the first dose of study drug up to 30 days after the last dose of study drug (approximately up to 6.6 years)
