A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria and are reported as outside of the normal reference range for healthy volunteers may be included only if the Investigator considers the finding is unlikely to introduce additional risk to the subject and will not interfere with the study procedures.
* Body weight >50 Kilograms(kg) (110 pounds) for men and >45kg (99pounds) women and a body mass index (BMI) between 18.5-32 kg/meter^2 inclusive will be allowed.
* Male or female between 18 and 55 years of age inclusive, at the time of signing the informed consent.
* A female subject is eligible to participate if she is of: Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy [for this definition, "documented" refers to the outcome of the investigator's/designee's review of the subject's medical history for study eligibility, as obtained via a verbal interview with the subject or from the subject's medical records]; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) >40 milli international unit [MlU]/milliliter [mL] and estradiol <40 picogram [pg]/mL [<147 picomoles /litre] is confirmatory]..
* Male subjects with female partners of child-bearing potential must agree to use contraception method. This criterion must be followed from the time of the first dose of study medication until the follow up visit.his criterion must be followed from the time of the first dose of study medication until the follow up visit (7 to 14 days post last dose).

Each episode of ischemia must be separated by a minimum duration of at least 1 minute, during which the ST segment returns back to baseline (1x1x1 rule).
