* Female participant must be of non-childbearing potential, defined as: a) Postmenopausal: A postmenopausal state is defined as no menses for 12 months without an alternative medical explanation. A high follicle stimulating hormone (FSH) level (greater than \[\>\]40 international unit per liter \[IU/L\] or milli international unit per milliliter \[mIU/mL\]) in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, 2 FSH measurements will have to be taken at least 3 months apart, OR b) Permanently sterile - permanent sterilization methods include hysterectomy, bilateral salpingectomy, bilateral tubal occlusion/ligation procedures, and bilateral oophorectomy Male participants must either: a) be surgically sterile (have had a vasectomy), or otherwise incapable of fathering a child, OR b) if heterosexually active, have a partner who is postmenopausal (as defined above), permanently sterile (as defined above), or otherwise incapable of becoming pregnant, OR c) if heterosexually active with a woman of childbearing potential, agree to use effective methods of contraception as detailed in Prohibitions and Restrictions section, from screening onwards, and agree to continue to use the same method of contraception throughout the study and for at least 90 days after the last dose of study drug Contraceptive use should be consistent with local regulations regarding the use of contraceptive methods for participants participating in clinical studies
* Female participants should have a negative pregnancy test at screening and on Day -1
* Participants must be non-smokers for at least 3 months prior to screening
* Participants must have a body mass index (BMI; weight in kilogram \[kg\] divided by the square of height in meters) of 18.0 to 30.0 kilogram per meter square (kg/m\^2), extremes included. (Williamson 1993)

Any evidence of heart block is exclusionary. Any evidence of left or right bundle branch block is exclusionary Note: Retesting for abnormal QTc interval value that may lead to exclusion will be allowed once without prior approval from the Sponsor. Retesting may take place during an unscheduled visit in the screening phase. Participants with a normal value at retest may be included
* Participants must be healthy on the basis of a medical evaluation that reveals the absence of any clinically relevant abnormality and includes a physical examination, medical history, vital signs, and the results of blood chemistry, blood coagulation and hematology tests, and a urinalysis performed at screening
* Participant must be willing and able to adhere to the prohibitions and restrictions specified in Prohibitions and Restrictions section
* In the Investigator's opinion, the participant is able to understand and comply with protocol requirements, instructions, and study restrictions and is likely to complete the study as planned
* Participant must sign a separate if he or she agrees to provide an optional deoxyribonucleic acid (DNA) sample for research. Refusal to give consent for the optional DNA research sample does not exclude a participant from participation in the study

EXCLUSION CRITERIA Any potential participant who meets any of the following criteria will be excluded from participating in the study

* Participants with a past history of cardiac arrhythmias (for example, extrasystoli, tachycardia at rest), history of risk factors for Torsade de Pointes syndrome (for example, hypokalemia, family history of long QT Syndrome) or history or other clinical evidence of significant or unstable cardiac disease (for example, angina, congestive heart failure, myocardial infarction, diastolic dysfunction, significant arrhythmia, coronary heart disease, and/or clinically significant ECG abnormalities), moderate to severe valvular disease or uncontrolled hypertension at screening. Any evidence of heart block or bundle branch block is also exclusionary
* Participants with any current or previous illness that, in the opinion of the Investigator, might confound the results of the study or pose an additional risk in administering study drug to the participant or that could prevent, limit, or confound the protocol specified assessments. This may include but is not limited to renal dysfunction (estimated creatinine clearance below 60 milliliter per minute \[mL/min\] at screening, calculated by the Modification of Diet in Renal Disease \[MDRD\] formula \[Poggio 2005\]), significant cardiac, vascular, pulmonary, gastrointestinal (such as significant diarrhea, gastric stasis, or constipation that in the Investigator's opinion could influence drug absorption or bioavailability), endocrine, neurologic, ophthalmic, hematologic, rheumatologic, psychiatric, neoplastic, or metabolic disturbances. Any condition possibly affecting drug absorption (for example, gastrectomy or other significant gastrointestinal tract surgery, such as gastroenterostomy, small bowel resection, or active enterostomy) will also lead to exclusion
* Participants with any history of clinically significant skin disease such as, but not limited to, dermatitis, eczema, drug rash, psoriasis, food allergy, and urticaria
* Participants with a history of clinically significant drug allergy such as, but not limited to, sulfonamides and penicillins, or drug allergy witnessed in previous studies with experimental drugs
