About this study

Official title: Clinical, Radiological, Tissue and Biological Phenotyping for the Analysis of the Transition From Physiology to Pathology in Pulmonary Diseases With Pulmonary Hypertension.

This is a monocentric, case-control, comparative study aiming at investigating the transition from physiological to pathological pulmonary circulation in patients with pulmonary hypertension (PH) and chronic lung diseases. The study will include 105 adults participants undergoing lung surgery, divided into three groups, Group A (patients with chronic lung disease and PH undergoing lung transplantation), Group B (patients with chronic lung disease without PH), and Group C (patients without chronic lung disease nor PH). The primary objective is to identify the association between vascular remodeling and PH by measuring the medial thickness of pulmonary arteries. Secondary objectives include multimodal phenotyping (clinical, radiological, tissue, and biological) to explore mechanisms of PH development. Blood, broncho-alveolar lavage, and lung tissue samples will be collected during routine care. The study aims to improve understanding of PH pathophysiology and identify potential biomarkers and therapeutic targets.

Being tested

What is being measured

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

  1. Percentage of pulmonary artery media thickness measured by optical microscopy

    Measured: Surgical intervention

Secondary outcomes (9)
  1. Quantify endovascular (angiophagy) and perivascular (fibrosis, pro-inflammatory cells) tissue lesions.

    number of stage I, II and III angiophagia lesions relative to the number of arteries analyzed on a field of anatomopathology slides and classified according to artery diameter; surface area of pulmonary fibrosis relative to the total surface area of the tissue field explored; quantification of immune system cells in interstitial tissue relative to the tissue surface area explored.

    Measured: Surgical intervention

  2. Compare the radiological phenotyping of patients with pulmonary hypertension and without pulmonary hypertension, determined from patient lung scans

    Measured: Baseline

  3. Compare cardiorespiratory functional clinical phenotyping between patients with pulmonary hypertension and without pulmonary hypertension.

    Using generalized linear model for assesment of respiratory function tests, 6-minute walk test and echocardiography of patients

    Measured: Baseline

  4. Compare the biological phenotyping of biological lung inflammation from bronchioloalveolar lavage of patients with pulmonary hypertension and without pulmonary hypertension.

    Dosage of inflammatory proteins (IL1, IL10, IL6, etc.) and cytological analysis of bronchioloalveolar lavage

    Measured: Surgical intervention

  5. High-throughput proteomic quantification indices of circulating serum from patients with pulmonary hypertension compared with patients without pulmonary hypertension.

    Measured: Baseline

  6. Compare the phenotyping of pulmonary vascular microstructure by microCT in patients with pulmonary hypertension and without pulmonary hypertension.

    Measured: Surgical intervention

  7. Compare protein tissue phenotyping of pulmonary hypertension regulatory pathways in patients with and without pulmonary hypertension evaluated with Elisa tests on lung parenchyma.

    Measured: Surgical intervention

  8. Evaluate the statistical relationships between tissue vascular remodeling and tissue, alveolar, and blood protein alterations.

    Measured: Baseline and surgical intervention

  9. Compare genetic tissue phenotyping of pulmonary hypertension regulatory pathways in patients with and without pulmonary hypertension evaluated with PCR tests on lung parenchyma.

    Measured: Surgical intervention

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Hypertension and Chronic Pulmonary Disease, run by Assistance Publique Hopitaux De Marseille.

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 8 inclusion and 2 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: opening soon, as of the sponsor's last update on 22 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of pulmonary artery media thickness measured by optical microscopy (time frame: Surgical intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Sep 2025.
