A Phase 1, Bio-equivalence Study of TAK-536 Pediatric Formulation

The purpose of this study is to evaluate the bio-equivalence of a single oral administration of TAK-536 pediatric formulation (granules) in comparison with a TAK-536 commercial formulation (tablet) in healthy adult male participants in an open label, 2-period, 2-treatment, cross-over design.

• Has received TAK-536 or TAK-491 in a previous clinical study or as a therapeutic agent.
• Has uncontrolled, clinically significant neurologic, cardiovascular, pulmonary, hepatic, renal, metabolic, gastrointestinal, or endocrine disease or other abnormality, which may impact the ability of the participant to participate or potentially confound the study results.

• 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.
