Clinical Trial Summary

Patients with interstitial lung disease (ILD) and scleroderma who develop pulmonary hypertension (PH) do not fit well into the current classification system and treatments for pulmonary hypertension. This study aims to better understand patients with ILD-PH and scleroderma and to determine if treatment with Macitentan is beneficial.


Clinical Trial Description

The investigators aim to use pressure-volume loop derived right ventriculo-vascular coupling, pulmonary impedance, and invasive cardiopulmonary exercise testing (CPET) to:

1. Comprehensively phenotype patients with scleroderma ILD-PH and pulmonary vascular exercise limitation (PVL) relative to scleroderma ILD-PH without PVL.

2. Compare the efficacy of chronic Macitentan therapy in improving 1) right ventricular hemodynamics 2) exercise capacity and 3) symptoms in scleroderma ILD-PH patients with and without PVL. ;
