Summary:

      With the pharmacokinetics (PK) of centanafadine currently being evaluated in adults. The PK
      of extended-release centanafadine may differ in children compared to adults due to
      physiological differences in the gastrointestinal tract. The information in this trial will
      support pediatric dose selection in future trials.
