Study Overview

Detailed Description

This a 3-part drug-drug interaction (DDI) study.

All the 3 parts of the study includes:

  • Screening Period: 27 days (Day -28 through Day -2)
  • Two Treatment Periods:

    • Part 1: Treatment Period 1 (Day -1 through Day 8) and Treatment Period 2 (Day 1 through Day 12)
