About this study

Sickle cell disease (SCD) is the most common inherited disease of the world affecting African and Caribbean populations. SCD is caused by the homozygous inheritance of the gene for sickle hemoglobin (HbS). Most patients with SCD develop abnormal pulmonary function characterized by airway obstruction, restrictive lung disease, abnormal diffusing capacity, hypoxemia and pulmonary hypertension In healthy subjects, lung capillary blood volume (Qc) and membrane diffusing capacity (Dm) can be accurately measured by the nitric oxide-carbon monoxide (NO-CO) method. We propose to study, for the first time, lung capillary blood volume and alveolar membrane diffusing capacity, using the NO-CO method, in children with SCD aged of at least 6 years Early determination of lung function and pulmonary circulation in children with SCD is very important, not only for the understanding of physiopathologic mechanisms of the disease but also for a better therapeutic management of these children.

Read the detailed description

We propose to study, for the first time, lung capillary blood volume and alveolar membrane diffusing capacity, using the NO-CO method, in children with SCD aged of at least 6 years. We will compare lung function and measurement of Qc and Dm in 2 groups of 120 subjects, one group of SCD children, and the other of normal children matched on age and ethnic origin. Measurement of lung capillary blood will be measured twice, to assess short term reproducibility. The measurement will be done in sitting position and lying down for one part of subjects, and at rest and during a moderate rectangular exercise for the other part of subjects. These different tests are designed to assess the physiological adaptation of pulmonary circulation in these two populations of children. Combined with complete lung function measurements, echocardiographic assessment of pulmonary hemodynamics, and measurement of exhaled nitric oxide, these evaluations will lead to a better understanding of pathophysiology of lung injury in SCD. The study will be completes at Robert Debré Hospital, in close collaboration with Sickle Cell Disease Center and Physiology Department. Children will be included after informed consent signed, as legally prescribed.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing NO-CO inhalation and expiration in people with Sickle Cell Disease, run by Assistance Publique - Hôpitaux de Paris 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 4 inclusion and 5 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 3 Feb 2023. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Study of lung capillary blood volume and alveolar membrane diffusing capacity using NO-CO method (time frame: The day of the measure). 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 NCT00560261, 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 3 Feb 2023.
