A Study to Assess the Effect of Food Intake and Drug-drug Interactions of E7090 When Co-administered With Rabeprazole or Rifampin in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
This study will have three parts: Part A, Part B, and Part C. The primary purpose of Part A is to evaluate the effect of food on the rate and extent of E7090 absorption following single oral doses of E7090 in healthy participants, Part B is to evaluate the effects of rabeprazole (a gastric acid-reducing agent) on the rate and extent of E7090 absorption following single oral doses of E7090 in healthy participants, Part C is to evaluate the effects of rifampin (a strong Cytochrome P450 3A [CYP3A] inducer) on pharmacokinetics (PK) of single oral doses of E7090 in healthy participants.
