Chronic Thromboembolic Disease Registry

Study Purpose

The goal of this patient registry is to learn about the natural history in patients with chronic thromboembolic disease (CTD) and/or chronic thromboembolic pulmonary hypertension (CTEPH). The main question[s] it aims to answer are:

  • - Long-term outcome after various types of treatment, including medication, balloon pulmonary angioplasty, and pulmonary endarterectomy.
  • - Effect of treatment on patient's quality of life and exercise tolerance Participants will be followed longitudinally to assess their health outcomes and quality of life via chart review and health quality surveys.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Patients referred with CTED and/or CTEPH defined as: 1.
Mean pulmonary arterial pressure (mPAP) > 20 mmHg at rest with pulmonary vascular resistance (PVR) > 2 Wood units (WU); or if mPAP ≤ 20 mmHg or PVR ≤ 2 WU at rest, have exercise limitations from chronic thromboembolic pulmonary disease (CTEPD) without pulmonary hypertension (PH) 2. Radiologic finding of chronic thromboembolic disease, including abnormal ventilation perfusion scan, pulmonary angiogram, computer tomographic pulmonary angiogram, or magnetic resonance pulmonary angiogram. 3. Post-embolic exercise intolerance and evidence of chronic thromboembolic disease in the absence of resting pulmonary hypertension.
  • - Treatment with anticoagulation for ≥ 3 months before diagnosis of CTEPH or CTEPD without PH.
  • - Age ≥ 18 years.

Exclusion Criteria:

- Main cause of PH other than World Health Organization (WHO) group 4 (CTEPH) - Patient's refusal to participate in clinical research and/or receive intervention

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT05843500
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
