Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Iloprost; The study enrolled patients who were already using iloprost with PD-6 without any safety or tolerability concerns, thereby facilitating a direct comparison of the PD-15 to the PD-6. The single-arm design allowed each patient to serve as his/her own control

Drug: Iloprost PD-6; Period 1 (PD-6): study period defined as the 14 days prior to the first dose of study iloprost inhalation with PD-15. Commercial iloprost inhalation solution delivered using the Power Disc-6 with the I-neb® Adaptive Aerosol Delivery (AAD®) system administered 6 to 9 times per day; Other Names: Ventavis; Drug: Iloprost PD-15; Period 2 (PD-15): study period between the administration of the first dose with PD-15 on Day 1 until Day 28 inclusive. Period 3 (PD-15): study period from Day 29 until discontinuation of the PD-15. Commercial iloprost inhalation solution delivered using the Power Disc-15 with the I-neb® Adaptive Aerosol Delivery (AAD®) system administered 6 to 9 times per day; Other Names: Ventavis
