Brief Summary
This prospective open-label matched-control pilot study evaluates whether inhaled treprostinil improves exercise pulmonary vascular resistance and functional outcomes in adults with interstitial lung disease or connective tissue disease and exercise-induced pulmonary hypertension. Participants will receive inhaled treprostinil plus standard care or standard care alone and will be followed for 6 months, with an optional extension to 12 months.

Outcome Measures
Primary Outcomes (1)
Change in Exercise Pulmonary Vascular Resistance (PVR)
Change in exercise pulmonary vascular resistance (PVR) from baseline to Month 6, measured during exercise right heart catheterization with invasive cardiopulmonary exercise testing (iCPET). The primary analysis will compare the change in exercise PVR between the inhaled treprostinil and standard-of-care groups
Baseline to Month 6
Secondary Outcomes (10)
Incidence of Adverse Events and Treatment Discontinuations
Through Month 6
Progression to Resting Pulmonary Hypertension
Month 12
Change in Exercise Pulmonary Vascular Resistance (PVR) at Month 12
Month 12
Change in Right Ventricular Stroke Work Index (RVSWI) at Month 6
Baseline to Month 6
Change in Pulmonary Arterial Compliance at Month 6
Baseline to Month 6
- +5 more secondary outcomes
Study Arms (2)
Inhaled Treprostinil Plus Standard of Care
EXPERIMENTALParticipants receive inhaled treprostinil (Tyvaso) in addition to standard disease-specific care.
Standard of Care
ACTIVE COMPARATORParticipants receive standard disease-specific care without inhaled treprostinil
Interventions
Description: * Initial dose 18 mcg four times daily * Titrated to 54-72 mcg four times daily as tolerated Standard disease-specific therapy continues
