The Impact of Inhaled Treprostinil on Dyspnea and Exercise Intolerance in Mild COPD; a Pilot and Feasibility Trial
Source: ClinicalTrials.gov · Last updated 8 Jul 2026
Brief summary (registry, in English)
The goal of this clinical trial is to evaluate the impact of inhaled Treprostinil on breathlessness and low exercise capacity in patients living with mild chronic obstructive pulmonary disease. Participants will be asked to: * Perform lung function and exercise tests * Have ultrasound of their heart * Have CT images of their lungs * Visit the lab on 5 different occasions (plus one visit to the CT imaging clinic) The researchers will compare the effectiveness and feasibility of inhaled Treprostinil to improve breathlessness upon exertion and exercise capacity
