Study population: Patients dianosed with CTEPH according to the contemporary guidelines

Who may be able to join

  • Patients must be diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH)
  • Patients must be willing to provide informed consent
  • Patients must meet the following criteria for CTEPH:

About this study

Official title: A Chinese Real-world Study to Investigate the Management Pattern and Outcomes of Chronic Thromboembolic Pulmonary Hypertension (CHANGE Study)

The Change Database is a prospective, observational multi-center disease registry, which will collect data on patients with chronic thromboembolic pulmonary hypertension (CTEPH) in China. It aims to illustrate the epidemiology, management and long-term outcomes of CTEPH.

Read the detailed description

18 CTEPH centers will be enrolled in the study. The epidemiology, diagnosis,treatments (pulmonary endarterectomy (PEA), balloon pulmonary angioplasty (BPA) and targeted medical therapy), and long-term prognosis of CTEPH will be evaluated.

Being tested
pulmonary endarterectomy or balloon pulmonary angioplasty

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • pulmonary endarterectomy or balloon pulmonary angioplastyProcedure or surgery

    Also called PEA or BPA

    A multidisciplinary team make the final treatments for patients with CTEPH depending on their disease and preferences.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. death

    all-cause death

    Measured: 3 years

  2. The change in mean pulmonary artery pressure (mPAP) in millimetre of mercury (mmHg), pulmonary vascular resistance (PVR) in Wood units, cardiac output (CO) in liter per minute (L/min) or cardiac index (CI) in liter per minute (L/min).

    mPAP, PVR, CO, and CI constitute critical parameters in hemodynamic assessments.

    Measured: 3 years

  3. The change in 6-minute walk distance in meter, in BNP or NT-proBNP in picograms per milliliter(pg/ml), or WHO-functional class.

    The 6-minute walk distance, BNP or NT-proBNP levels, and WHO-functional class are parameters used in the evaluation of functional capacity.

    Measured: 3 years

Secondary outcomes (2)
  1. lung or heart and lung transplantation

    proportion of patients experiencing lung or heart and lung transplantation due to severe right heart failure during the study

    Measured: 3 years

  2. changes of health related quality of life

    change of quality of life measured with the EQ-5D-5L or EmPHasis-10

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Thromboembolic Pulmonary Hypertension, run by China-Japan Friendship Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Zhenguo Zhai, Ph.D. (+86 10 84206269, zhaizhenguo2011@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

death (time frame: 3 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05311072, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2024.
