Brief summary: This study is designed to first evaluate the effect of food on E7050's pharmacokinetic parameters following the administration of single 100 mg oral doses of E7050 tablet to each normal healthy participant in the study (Part A), and second to characterize E7050 pharmacokinetics after single doses at 200 mg and 400 mg under fasted conditions (Part B). Part A will be a randomized, single-dose, open-label, three-treatment period crossover study. Part B is a nonrandomized, open-label, two-treatment sequential study design. Twelve participants in Treatment Period 1 will receive a single dose of 200 mg of E7050 under fasted conditions. Following review of safety data of the 200 mg dose level, an additional 12 subjects will then receive a single dose of 400 mg of E7050 in Treatment Period 2.


Eligibility criteria: Inclusion criteria:

Subjects must meet all of the following criteria to be included in this study:

1. Normal healthy adult males and females (age 18-45 years).
2. Body Mass Index (BMI) greater than or equal to 18 and less than or equal to 32 at the time of Screening.
3. Pregnancy or lactation. Female patients of childbearing potential must have a negative pregnancy test before inclusion into the study, and must agree to use medically acceptable methods of contraception (eg, abstinence, condom + spermicide, or a double-barrier method \[eg, condom + diaphragm with spermicide\], or intrauterine device (IUD), or have a vasectomised partner) starting at Screening and throughout the entire study period and for 2 months after the last dose of study drug. Those female patients using hormonal contraceptives must also be using an additional approved method of contraception (as described previously) starting at Cycle 1 Day 1, and continuing throughout the entire study period and for 2 months after the last dose of study drug. Postmenopausal women must have been amenorrheic for at least 12 consecutive months; otherwise a pregnancy test is required. Male patients must agree to use contraceptive methods (eg, abstinence, condom + spermicide or a double-barrier method \[eg, condom + partner diaphragm with spermicide\]).
4. Non-smokers.
5. Willing and able to comply with all aspects of the protocol.
6. Provide written informed consent.

Exclusion Criteria:

Participants who meet any of the following criteria will be excluded from this study:

1. Evidence of clinically significant cardiovascular, hepatic, gastrointestinal, renal, respiratory, endocrine, hematological, neurological, or psychiatric disease or abnormalities or a known history of any gastrointestinal surgery that could impact the pharmacokinetics of study drug.
2. Clinically significant illness within 8 weeks or a clinically significant infection within 4 weeks of dosing.
3. Evidence of organ dysfunction or any clinically significant deviation from normal in their medical history.
4. Evidence of clinically significant deviation from normal in physical examination, vital signs, or clinical laboratory determinations at Screening or Baseline.
5. An interval corrected for heart rate (QTcF) interval greater than 450 msec at Screening or Baseline.
6. Females who are either pregnant or lactating.
7. A known or suspected history of drug or alcohol abuse within 6 months prior to screening, or who have a positive urine drug test or alcohol test at Screening or Baseline.
8. Positive results for Hepatitis B surface antigen (HBsAg) or Hepatitis C antibody (HCV) screen.
9. Diagnosis of acquired immune deficiency syndrome (AIDS), or positive test for human immunodeficiency virus (HIV).
10. Participation in another clinical trial less than 4 weeks prior to dosing or current enrollment in another clinical trial.
11. Receipt of blood products within 4 weeks, or donation of blood within 8 weeks, or donation of plasma within 1 week prior to dosing.
12. Hemoglobin level less than 12.0 g/dL.
13. Known history of any significant drug or food allergy or an ongoing seasonal allergy.
14. Use of prescription drugs within 2 weeks prior to Screening (unless drug has a long t1/2, ie, 5 x t1/2 exceeds 2 weeks).
15. Use of over-the-counter (OTC) medications within a minimum of 2 weeks prior to dosing.
16. Requiring a special diet or taking dietary aids known to modulate drug metabolizing enzymes, or who have consumed foods/beverages or herbal preparations containing Kava root, Ginkgo Biloba Extract (GBE), or St. John's Wort within 4 weeks of Baseline Period 1.
17. Known intolerance to the study drug (or any of the excipients).
18. Any medical or other condition which, in the opinion of the investigator, would preclude participation in a clinical trial.
