Arm Groups

ArmDescriptionAssigned Intervention
Cohort 1 Cohort 1 will include approximately 500 patients who are not receiving inhaled treprostinil at time of study enrollment.
  • Other: Prospective study assessments
    Patients will complete prospective assessments at 6- and 12-month intervals for up to 5 years. There will be 1 check in at the first 3 months of enrollment. Follow up visits will include a ±45 day visit window. If an assessment is performed within 45 days of the visit window as part of the patient's standard of care, those values will be used in place of a prospective assessment.
Cohort 2 Cohort 2 will include approximately 150 patients who are newly initiated on Tyvaso/Tyvaso DPI. For patients to be eligible for Cohort 2, they must have initiated Tyvaso/Tyvaso DPI at Baseline or ≤ 60 days prior to Baseline.
  • Other: Prospective study assessments
    Patients will complete prospective assessments at 6- and 12-month intervals for up to 5 years. There will be 1 check in at the first 3 months of enrollment. Follow up visits will include a ±45 day visit window. If an assessment is performed within 45 days of the visit window as part of the patient's standard of care, those values will be used in place of a prospective assessment.
Cohort 3 Cohort 3 will include approximately 350 patients who have been receiving Tyvaso/Tyvaso DPI for > 60 days prior to Baseline.
  • Other: Prospective study assessments
    Patients will complete prospective assessments at 6- and 12-month intervals for up to 5 years. There will be 1 check in at the first 3 months of enrollment. Follow up visits will include a ±45 day visit window. If an assessment is performed within 45 days of the visit window as part of the patient's standard of care, those values will be used in place of a prospective assessment.

Detailed Description

The purpose of this study is to observe and capture demographic characteristics, treatment patterns, and clinical outcomes of interest for patients with PH-ILD to further clinical understanding of the epidemiological landscape and outcomes of the disease and treatment. In this registry, patients will be enrolled into 1 of 3 cohorts. Cohort 1 will include approximately 500 patients who are not receiving inhaled treprostinil at time of study enrollment. Cohort 2 will include approximately 150 patients who are newly initiated on Tyvaso/Tyvaso DPI. Cohort 3 will include approximately 350 patients who have been receiving Tyvaso/Tyvaso DPI for >60 days. As part of the registry, assessments will be completed for data collection in 6- or 12 month intervals, unless the data are already available via standard of care. This patient registry will follow patients for up to 5 years after enrollment. Assessments include pulmonary function tests (PFTs) including diffusing capacity of the lungs for carbon monoxide (DLCO); high resolution computed tomography (HRCT); vital signs; 6-Minute Walk Test; blood draw for plasma N-terminal pro-BNP (NT-proBNP) concentration, genetics analysis, biomarker analysis; echocardiography; EuroQoL 5 Dimension 5 Level Questionnaire (EQ-5D-5L); King's Brief Interstitial Lung Disease Questionnaire (K-BILD); Living with Pulmonary Fibrosis Questionnaire (L-PF); Therapy Administration Questionnaire; healthcare resource utilization; current medications and rehabilitation; WHO functional class; transplant status; survival data; and RHC.
