Summary:

      This first-in-human study has three parts. In Parts A and B, the safety, tolerability, and
      pharmacokinetics (PK) will be evaluated following administration of single and multiple doses
      of KRP-A218, including food-effect. In Part C, the drug-drug interaction (DDI) with
      itraconazole will be evaluated.
