Study Description

Brief Summary

This is a Phase 4, single-center, open-label, fixed-sequence, multiple-dose, 2-way drug-drug interaction study.

Condition or Disease Intervention/Treatment Phase
  • Drug: Pitavastatin (NK-104)
  • Drug: Diltiazem (Cardizem LA) 240 mg QD
Phase 4

Detailed Description

Each subject will qualify for entry into the study not more than 30 days prior to admission into the clinical unit. Subjects will check into the clinical unit on Day -1 for baseline assessments. During the treatment period, each subject will receive a once-daily dose of pitavastatin 4 mg on Days 1 through 5 and on Days 11 through 15 and a once-daily dose of diltiazem 240 mg on Days 6 through 15. Subjects will fast overnight for at least 8 hours before dosing and will remain fasted until 4 hours after dosing on the morning of Days 5, 10, and 15.
