| NCT01018368 | Study of VX-770 and Rifampin in Healthy Male Subjects | PHASE1 | COMPLETED | 24 | — | — | Nov 1, 2009 | Mar 1, 2010 | May 10, 2010 | 1 | United States |
Subjects inhaled hyperpolarized helium-3 (3He) gas mixed with nitrogen to make a total volume of approximately one-third forced vital capacity (FVC) to a maximum of 1 liter and hold their breath for 20 seconds or less. Rapid magnetic resonance imaging (MRI) was performed during inhalation/exhalation and/or breath-hold. Areas of decreased ventilation were observed as ventilation defects that are visualized as decreased (and/or absent) 3He intensity in 3He-MRI. The total ventilation defect was defined as the ratio of total ventilation defect volume (L) to total lung volume (L), expressed as a percentage. Baseline was defined as the most recent non-missing measurement collected before initial administration of study drug in VX-770 treatment phase (Day 15 to 42).

| Arm | Type | Description |
|---|---|---|
| VX-770 | EXPERIMENTAL | Part A: Subjects received placebo tablets matched to VX-770 150 milligram (mg) orally twice daily from Day 1 to 14 (Placebo run-in period), followed by VX-770 150 mg tablets orally twice daily from Day 15 to 42 (VX-770 treatment period), and then placebo tablets matched to VX-770 150 mg orally twice daily from Day 43 to 57 (Placebo washout period) during Part A of the study. Part B: Subjects received VX-770 150 mg tablets orally twice daily for 48 weeks during Part B of the study. Part B included subjects from Part A and newly enrolled subjects. |
