Title: TRIUMPH I: Double Blind Placebo Controlled Clinical Investigation Into the Efficacy and Tolerability of Inhaled Treprostinil Sodium in Patients With Severe Pulmonary Arterial Hypertension
Brief Summary: This is a double-blind placebo-controlled clinical investigation into the efficacy and tolerability of inhaled treprostinil in patients with severe pulmonary arterial hypertension. The primary outcome is the change in 6-minute walk distance from baseline to week 12.


Options:
A: Inclusion Criteria:

* Clinically stable, pulmonary arterial hypertension diagnosed as either idiopathic or familial PAH, collagen vascular disease associated PAH, HIV PAH, or PAH induced by anorexigens, New York Heart Association (NYHA) Class III or Class IV.
* Been on a stable dose of 125 mg twice daily (bid) of bosentan OR any stable dose of sildenafil for at least three months prior to study start
* An unencouraged six minute walk test (6MWT) of between 200 and 450 meters at screening
* Cardiac catheterization within the past 13 months consistent with PAH, specifically mean pulmonary artery pressure (PAPm) ≥25 mmHg (at rest), pulmonary capillary wedge pressure (PCWP) (or left ventricular end diastolic pressure) ≤15 mmHg, and pulmonary vascular resistance (PVR) \>3 mmHg/L/min
* Within the past 12 months, patients must have had a chest radiograph consistent with the diagnosis of PAH
* Willing and able to follow all study procedures

Exclusion Criteria:

* Considering pregnancy, are pregnant and/or lactating
* PAH due to conditions other than noted in the above inclusion criteria.
* Have had any change in or discontinued any PAH medication within the last three months, including but not limited to endothelin receptor antagonist (ERA), or calcium channel blockers (CCB) (with the exception of anticoagulants)
* Have received any prostanoid within the 30 days before screening or are scheduled to receive any during the course of the study
* Have received any investigational medication within 30 days prior to the start of this study or are scheduled to receive another investigational drug during the course of this study
* Have a known intolerance to any drug, especially to treprostinil sodium or prostanoids
* Have an increased risk of hemorrhage
* Have a new type of chronic therapy (e.g., a different category of vasodilator, diuretic) for PAH added within the last month, except anticoagulants
* Have any musculoskeletal disease or any other disease that would limit ambulation.
B: * INCLUSION CRITERIA
* Completion of the 16-week treatment period in the double-blind ASSET study
* Women of childbearing potential must have a negative result on their serum pregnancy test and use reliable methods of contraception during study treatment and for 3 months after study treatment termination.

Reliable methods of contraception are:

1. Barrier type devices (e.g., female condom, diaphragm, contraceptive sponge) only in combination with a spermicide.
2. Intra-uterine devices.
3. Oral, injectable, transdermal or implantable contraceptives only in combination with a barrier method.

Hormone-based contraceptives alone, regardless of the route of administration, are not considered to be reliable methods of contraception.

Abstention, rhythm method, and contraception by the partner alone are not acceptable methods of contraception.

Women not of childbearing potential are defined as prepubescent, postmenopausal (i.e., amenorrhea for at least 1 year), or surgically or naturally sterile.
