Primary Outcome Measures:
  • To assess the safety of Tyvaso ® as assessed by changes or stability of acute oxygenation (pulse oximetry) and spirometry (FEV1). [ Time Frame: This is a 4 week trial ]
    A 4-Week, Open Label Study Testing the Safety of Inhaled Treprostinil (Tyvaso®) in the Treatment of Pulmonary Hypertension (PH) Associated with Chronic Obstructive Lung Disease (COPD) (PH-COPD)


Secondary Outcome Measures:
  • New York Heart Association (NYHA) functional class [ Time Frame: Change in New York Heart Association (NYHA) functional class assessed at baseline and at week 4. ]
    A change in functional class is assessed as improvement or deterioration in the patient's functional status

  • Six minute walk distance [ Time Frame: Change from baseline in 6 minute walk distance at 4 weeks ]
    A change in how far the subject can walk in 6 minutes will be measured at baseline and compared to how far the subject can walk in 6 minutes at week 4.

  • Clinical Worsening [ Time Frame: From the time of randomization to until the subject discontinues from study for any cause, assessed up to 4 weeks ]
    Clinical worsening is described as Death, hospitalization (all cause)and COPD exacerbations (worsening of respiratory symptoms which require treatment with oral corticosteroids, antibiotics or both).

  • Peripheral Blood Mononuclear Cells (PBMC) phagocytic index (PI) and PBMC gene expression [ Time Frame: Change from baseline in PBMC PI and PBMC gene expression at 4 weeks ]

    The phagocytic index is the average number of bacteria ingested per phagocyte in an incubated mixture of bacteria, phagocytes, and blood serum. We will also be looking a a change in gene expression of these (PBMC) cells.


  • St. George's Chronic Obstructive Pulmonary Disease (COPD) questionnaire [ Time Frame: change from baseline in the St. George's respiratory questionnaire at 4 weeks ]
    The St. George's questionnaire is a quality of life questionnaire completed by the subject at baseline and at week 4.


Enrollment: 10
Study Start Date: December 2012
Study Completion Date: July 2016
Primary Completion Date: July 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treprostinil
Inhaled prostanoid therapy with Treprostinil
Drug: Inhaled Treprostinil Therapy
Treprostinil: Inhaled prostanoid therapy
Other Name: Tyvaso ®

Detailed Description:
This is a pilot study of 10 patients that have COPD-PH. Primary outcome measure is to see if this drug is safe for this patient population and the secondary measure is to see if the drug improves patient functional capacity.
