Summary:

      The purposes of this study are to evaluate BE between a single-dose of TAK-438ASA tablet
      versus a single-dose combination of TAK-438 tablet 10 milligram (mg) and aspirin
      enteric-coated tablet 100 mg in Japanese healthy adult men (Study 1), and to evaluate the
      effects of food on the pharmacokinetics of TAK-438ASA tablet in Japanese healthy adult men
      (Study 2).
