Details and patient eligibility

About

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.

Enrollment: 42 patients

Sex: All

Ages: 20 to 55 years old
