NCT00367770

Brief Summary

This 6-month open label study will evaluate the long term safety of bosentan (via oxygen saturation) and efficacy (exercise capacity) in patients who have completed the BREATHE-5 study (PAH related to Eisenmenger physiology). Treatment duration is 6 months.

Outcome Measures

Primary Outcomes (3)

  • Change in 6-minute Walk Distance

    from baseline to week 24

  • Change in Borg Dyspnea Index

    Borg scale a numerical scale for assessing dyspnea, from 0 representing no dyspnea to 10 as maximal dyspnea.

    from baseline to week 24

  • Number of Participants With a Change in WHO Functional Class

    Number of participants with a change in WHO functional class from baseline to week 24. A change from a higher to a lower functional class (i.e. III to II, III to I or II to I) is considered as an improvement.

    from baseline to week 24

Study Arms (1)

Tracleer

EXPERIMENTAL

The starting dose for all patients will be 62.5 mg b.i.d. At the Week 4 visit, patients who were started on 62.5 mg b.i.d. will be uptitrated to 125 mg b.i.d. if the 62.5 mg b.i.d. dose was well-tolerated.

Drug: Tracleer®

Interventions

Patients will receive up to 125 mg b.i.d. of Tracleer.
