Outcome Measures
Primary Outcome Measures
- Incidence of Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [Screening up to 28 days after the last dose of study drug at Day 85 (up to approximately 1 year 5 months)]
Safety assessments will consist of monitoring and recording all adverse events (AEs) and SAEs; laboratory evaluation for hematology, blood chemistry, and urine values; periodic measurement of vital signs and electrocardiograms (ECGs); the performance of physical examinations and chest X-ray test.
Secondary Outcome Measures
- Cmax: Maximum Observed Plasma Concentration for E6742 and its Metabolite (ER-001132963) on Days 1 and 15 [Days 1 and 15: 0-6 hours post-dose]
- Tmax: Time to Reach the Maximum Plasma Concentration (Cmax) for E6742 and its Metabolite (ER-001132963) on Days 1 and 15 [Days 1 and 15: 0-6 hours post-dose]
- AUC(0-6Hours): Area Under the Plasma Concentration Versus Time Curve from Time 0 to 6 Hours for E6742 and its Metabolite (ER-001132963) on Days 1 and 15 [Days 1 and 15: 0-6 hours post-dose]
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male or Female, age greater than or equal to (>=) 18 years and less than or equal to (<=) 75 years at the time of written informed consent
-
Body mass index (BMI) >=15 kilogram per square meter (kg/m2) and less than (<) 30 kg/m2 at screening
-

-
Meets at least one of the following criteria at screening:
-

Exclusion Criteria:
-
Females who are breastfeeding or pregnant at screening or baseline (as documented by a positive beta-human chorionic gonadotropin [ß-hCG] or human chorionic gonadotropin [hCG] test). 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
-
Females of childbearing potential who:
• Within 28 days before study entry, did not use a highly effective method of contraception, which includes any of the following:
-
total abstinence (if it is their preferred and usual lifestyle)
-

-
a contraceptive implant
-

-
have a vasectomized partner with confirmed azoospermia
-
Do not agree to use a highly effective method of contraception (as described above) throughout the entire study period and for 28 days after study drug discontinuation
-
Participants on an oral contraceptive must use an additional barrier method throughout the study and for 28 days after study drug discontinuation NOTE: 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 (that is, bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing). Approved or certificated for drugs or medical devices in Japan
-
Males who have not had a successful vasectomy (confirmed azoospermia) if their female partners meet the exclusion criteria above (that is, the female partners are of childbearing potential and are not willing to use a highly effective contraceptive method throughout the study period and for 5 times the half-life of the study drug plus 90 days after study drug discontinuation). No sperm donation is allowed during the study period and for 5 times the half-life of the study drug plus 90 days after study drug discontinuation
-
Any history of gastrointestinal surgery that may affect pharmacokinetic (PK) profiles of E6742 (example, hepatectomy, nephrectomy, digestive organ resection) at screening
-
