Summary
This is a 24-month, multi-center, prospective, open-label, safety evaluation in PAH subjects following transition from a stable dose of inhaled iloprost (Ventavis).
Subjects are to be evaluated for safety throughout the course of the study while secondary assessments will be conducted at Baseline, Week 6, Week 12, and Months 6, 12, 18 and 24 following initiation of treprostinil sodium.
