Trial summary

Non-invasive assessment of lung involvement is a crucial issue for the follow-up of cystic fibrosis patients. Currently, CT is the method of reference to evaluate and quantify the lung morphological changes in cystic fibrosis adults but it remains a radiation-based technique. Read more about this study

About this study

Official title: Assessment of Lung Involvement in Cystic Fibrosis Patients Using 1.5T MR Imaging With Ultrashort Echo Time (UTE) Pulse Sequences

Non-invasive assessment of lung involvement is a crucial issue for the follow-up of cystic fibrosis patients. Currently, CT is the method of reference to evaluate and quantify the lung morphological changes in cystic fibrosis adults but it remains a radiation-based technique. MRI with ultrashort echo time (UTE) pulse sequences is a promising non-ionizing alternative for lung imaging. The investigators' objective is to evaluate cystic fibrosis lung involvement using CT and MRI-UTE, and to test the agreement between both techniques.

Read the detailed description

Cystic fibrosis is a recessive autosomic fatal disease, affecting about 6000 people in France. Thanks to progress in symptomatic care, median survival is increasing. The lung involvement is the most common and responsible for most deaths. The evaluation of respiratory disease severity is based on pulmonary functional tests (PFT) and imaging. Multi-slice computed tomography (CT) is the method of reference to quantify lung involvement in cystic fibrosis. It detects respiratory lung involvement earlier than PFT, and it reveals lesions associated with the onset of respiratory exacerbations, the mortality increase and the reduction of quality of life. However CT provides ionizing radiation, thus limiting the possibility of long-term follow-up. MRI is a non-ionizing 3D imaging technique; nevertheless, lung MRI is technically challenging with the result that it is currently not used in routine practice. Indeed, both low proton density and susceptibility effects lead to very low signal intensity derived from lung parenchyma. Recently, pulse sequences with ultrashort echo time (UTE) have been implemented by the use of half radio-frequency excitations and radial projection reconstruction. These UTE sequences make it theoretically possible to retrieve more signal from the lung parenchyma. The investigators aim at using 3D T1-weighted UTE pulse sequences on a 1.5T magnet (Avanto dot, Siemens) in cystic fibrosis patients in order to assess lung involvement severity. Thirty three cystic fibrosis adults are expected to take part in the study. All will benefit from PFT, CT and MRI. The investigators' strategy is to establish a semi quantitative score of pulmonary severity (Helbich score) using MRI and CT in subjects, testing for correlations between MRI and CT measurements and assessing the reproducibility of lung lesions quantification using MRI. The investigators' objective is to demonstrate that MRI-UTE pulse sequence at 1.5T is accurate and reproducible in evaluating and quantifying pulmonary involvement in cystic fibrosis.

What is being measured

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

  1. Agreement between MRI and CT for scoring lung involvement in cystic fibrosis

    MRI and CT evaluation of lung lesions quantification in cystic fibrosis will be assessed by 2 blind radiologists.

    Agreement between both evaluation will be assessed during statistical analyses after study completion.

    Measured: During MRI and CT, Day one

Secondary outcomes (6)
  1. Cystic fibrosis lesions scoring extracted from CT and MR images

    MRI and CT evaluation of lung lesions quantification in cystic fibrosis will be assessed by 2 blind radiologists.

    Agreement between both evaluation will be assessed during statistical analyses after study completion.

    Measured: During MRI and CT, Day one

  2. MRI cystic fibrosis reproductibility scoring over the time

    MRI cystic fibrosis scoring will be assessed a second time the same blind radiologist

    Measured: During MRI, Day one

  3. Correlation between MRI cystic fibrosis scoring and PFT indexes

    Measured: Day one

  4. Correlation between MRI cystic fibrosis scoring and exacerbation number

    Measured: 12 month after Day one

    Measured: Day one and 12 month after Day one

  6. Evolution of MRI cystic fibrosis scoring after one year

    Measured: 12 month after Day one

Questions about this trial

What is this clinical trial studying?

A study testing MR measurements of lung morphological changes in cystic fibrosis (Avanto dot, Siemens) and CT measurements of lung morphological changes in cystic fibrosis in people with Cystic Fibrosis, run by University Hospital, Bordeaux at 1 site in France.

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 2 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: finished, as of the sponsor's last update on 27 Nov 2017. 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 France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Agreement between MRI and CT for scoring lung involvement in cystic fibrosis (time frame: During MRI and CT, Day one). 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 NCT02449785, 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?
