Experimental: Inhaled Treprostinil
Inhaled treprostinil delivered via an ultrasonic nebulizer with a target dosing regimen of 12 breaths (72 micrograms [mcg]) 4 times daily (QID)
Drug: Inhaled treprostinil solution
Treprostinil inhalation solution
Placebo Comparator: Placebo
Placebo delivered via an ultrasonic nebulizer for QID administration
Drug: Placebo solution
- Change from Baseline to Week 12 in 6MWD at Peak Exposure (10 to 60 minutes after Dosing) [ Time Frame: Baseline, Week 12 ]The intent of the 6-Minute Walk Test (6MWT) is a validated and reliable measure of exercise ability in participants with chronic respiratory diseases.
- Change from Baseline to Week 12 in Moderate to Vigorous Physical Activity (MVPA) [ Time Frame: Baseline, Week 12 ]MVPA measured by actigraphy
- Change from Baseline to Week 12 in Overall Activity [ Time Frame: Baseline, Week 12 ]Activity measured by actigraphy
- Change from Baseline to Week 12 in Borg Dyspnea Score [ Time Frame: Baseline, Week 12 ]The Borg dyspnea score is a 10 point scale rating the maximum level of dyspnea experienced during the 6MWT. Scores range from 0 (no dyspnea at all) to 10 (very, very severe dyspnea).
- Change from Baseline to Week 12 in 6MWD/Borg Dyspnea Composite Score [ Time Frame: Baseline, Week 12 ]
- Change from Baseline to Week 12 in Quality of Life (QOL) Measured by St. George's Respiratory Questionnaire (SGRQ) [ Time Frame: Baseline, Week 12 ]The SGRQ is a designed to measure impact on overall health, daily life, and perceived well-being in participants with obstructive airways disease. Scores range from 0 to 100, with higher scores indicating more limitations.
- Change from Baseline to Week 12 in QOL measured by the University of California San Diego Shortness of Breath Questionnaire (UCSD SOBQ) [ Time Frame: Baseline, Week 12 ]The UCSD SOBQ is a self-administered rating of dyspnea associated with activities of daily living. The questionnaire uses a 6-point scale where 0 = "not at all" and 5 = "maximal or unable to do because of breathlessness"
- Change from Baseline to Week 12 in Plasma Concentration of N-terminal Pro-brain Natriuretic Peptide (NT-proBNP) Levels [ Time Frame: Baseline, Week 12 ]The NT-proBNP concentration is a biomarker associated with changes in right heart morphology and function.
- Change from Baseline to Week 12 in Patient Global Assessment (PGA) [ Time Frame: Baseline, Week 12 ]The PGA is used to rate participant fatigue and shortness of breath. Participants will use the Sponsor-provided smart device for at-home capture of PGA data.
