Has taken any excluded medication, supplements, dietary products, or food products during the time periods specified in the protocol. Has any current or recent (within 6 months) gastrointestinal diseases that would be expected to influence the absorption of drugs (that is, a history of malabsorption, esophageal reflux, peptic ulcer disease, erosive esophagitis, frequent [more than once per week] occurrence of heartburn, or any surgical intervention). Has a history of cancer, except basal cell carcinoma which has been in remission for at least 5 years prior to Day 1 of Period 1. Has a positive test result for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody, human immunodeficiency virus (HIV) antibody/antigen, or serological reactions for syphilis at Screening. Has poor peripheral venous access. Has undergone whole blood collection of at least 200 milliliter (mL) within 4 weeks (28 days) or at least 400 mL within 12 weeks (84 days) prior to the start of the study drug administration in Period 1. Has undergone whole blood collection of at least 800 mL in total within 52 weeks (364 days) prior to the start of the study drug administration in Period 1. Has undergone blood component collection within 2 weeks (14 days) prior to the start of the study drug administration in Period 1. Has an abnormal (clinically significant) ECG at Screening or prior to the study drug administration in Period 1. Has abnormal laboratory values that suggest a clinically significant underlying disease, or participant with the following laboratory abnormalities at Screening or prior to the study drug administration in Period 1: alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) greater than (>) 1.5 * the upper limits of normal (ULN). Who, in the opinion of the investigator or sub-investigator, is unlikely to comply with the protocol or is unsuitable for any other reason.

| Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs) | An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant who has signed informed consent to participate in a study; it does not necessarily have to have a causal relationship with this treatment or study participation. An AE can therefore be any unfavorable and unintended sign (for example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the study participation, whether or not it is considered related to the drug. A TEAE is defined as an adverse event with an onset that occurs after receiving study drug. | Baseline up to Day 6 of Intervention Period 2 (Day 18) | 
| Number of Participants With TEAEs Related to Vital Signs |  | Baseline up to Day 6 of Intervention Period 2 (Day 18) | 
| Number of Participants With TEAEs Related to Body Weight |  | Baseline up to Day 6 of Intervention Period 2 (Day 18) | 
| Number of Participants With TEAEs Related to Electrocardiograms (ECGs) |  | Baseline up to Day 6 of Intervention Period 2 (Day 18) | 
| Number of Participants With TEAEs Related to Clinical Laboratory Tests |  | Baseline up to Day 6 of Intervention Period 2 (Day 18) |
