Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults aged 18 and older with a confirmed diagnosis of interstitial lung disease and pulmonary hypertension.
✕Probably not a fit
Patients who do not have a diagnosis of interstitial lung disease or those who are not eligible for the specified cohorts may not benefit from this registry.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational registry aims to collect and analyze data from patients diagnosed with pulmonary hypertension associated with interstitial lung disease (PH-ILD). It will enroll patients into three cohorts based on their treatment status with Tyvaso/Tyvaso DPI and will follow them for up to five years. Assessments will include pulmonary function tests, imaging, vital signs, and various questionnaires to capture treatment patterns and clinical outcomes. The goal is to enhance understanding of the disease's epidemiology and treatment effects in real-world settings.
Why it matters
Potential benefit: If successful, this registry could provide valuable insights that lead to improved management and treatment strategies for patients with PH-ILD.
How similar studies have gone: Other observational studies in similar patient populations have shown success in capturing meaningful data, suggesting that this approach is viable.

Inclusion Criteria: 1. Adults aged 18 years or older 2. Diagnosis of fibrotic ILD based on high-resolution computed tomography imaging, including but not limited to: 1. Idiopathic interstitial pneumonia, including idiopathic pulmonary fibrosis 2. Autoimmune ILD 3. Chronic hypersensitivity pneumonitis 4. Nonspecific interstitial pneumonia 5. Occupational lung disease 6. Combined pulmonary fibrosis and emphysema with fibrosis greater than the extent of emphysema on lung imaging as determined by the Investigator 3. For patients to be eligible for Cohorts 1 to 3: RHC confirmed PH (mean pulmonary artery pressure \>20 mmHg, pulmonary artery wedge pressure ≤15 mmHg, pulmonary vascular resistance \>2 WU). 4. For patients to be eligible for Cohort 1, they must not be receiving inhaled treprostinil at Baseline. 5. For patients to be eligible for Cohort 2, they must have initiated Tyvaso/Tyvaso DPI at 1 of the following time points: 1. Baseline 2. ≤90 days prior to Baseline 6. For patients to be eligible for Cohort 3, they must be receiving Tyvaso/Tyvaso DPI at Baseline and for \>90 days prior to Baseline. 7. For patients to be eligible for Cohort 4: Prior RHC not meeting the definition of PH as described in Inclusion Criterion 3 but has a pulmonary artery wedge pressure ≤15 mmHg. 8. Co-enrollment in other observational or interventional studies is permitted. 9. Patient is willing and able to provide informed consent and complete surveys/questionnaires in English or Spanish. Exclusion Criteria: 1. Confirmed diagnosis of Group 1, 2, 4, or 5 PH a. In cases in which a patient has a diagnosis of PH-ILD along with a concomitant diagnosis of another PH group (eg, Group 1), enrollment may be permitted at the Investigator's discretion if, in their clinical judgment, PH-ILD is the predominant driver of the patient's PH. 2. Confirmed diagnosis of Group 3 PH associated with lung diseases and or hypoxia other than fibrotic ILD, as outlined in Inclusion Criterion 2. 3. Patients receiving inhaled treprostinil (Yutrepia™) at Baseline. Patients receiving other forms of PH therapy will be eligible for enrollment.
