Study of VX-770 and Rifampin in Healthy Male Subjects
- Registration Number
- NCT01018368
- Lead Sponsor
- Vertex Pharmaceuticals Incorporated
- Brief Summary
The objectives of this study are to evaluate the effects of multiple doses of rifampin on the single-dose pharmacokinetics of VX 770.
- Detailed Description
This is a single-center, nonrandomized, open-label, 2-period, 1-sequence crossover study to investigate the safety, tolerability and pharmacokinetics of VX 770 when administered alone or with rifampin.
All enrolled subjects will receive the same treatments and undergo the same procedures. In Period 1, subjects will receive a single dose of VX 770 on Day 1. In Period 2, subjects will receive a daily dose of rifampin on Days 1 through 10 and a single dose of VX 770 on Day 6.
