Trial summary

Primary ciliary dyskinesia is an inherited respiratory disease caused by various functional and ultrastructural abnormalities of respiratory cilia. The genetic heterogeneity underlying PCD is extremely important and only few genes are clearly implicated in PCD. Their mutations account for about 20% of patients. Read more about this study

About this study

Official title: Molecular Diagnosis of Primary Ciliary Dyskinesia

Primary ciliary dyskinesia is an inherited respiratory disease caused by various functional and ultrastructural abnormalities of respiratory cilia. The genetic heterogeneity underlying PCD is extremely important and only few genes are clearly implicated in PCD. Their mutations account for about 20% of patients. For all the other PCD patients, the genes responsible for their ciliary defect remain to be identify.

Read the detailed description

1/ Evaluating the frequency of mutations of the two main genes implicated in PCD, in a large cohort of patients with PCD confirmed by ciliary investigations.2/ Identifying and testing new candidate genes responsible not only for typical PCD and related disorders of the axoneme, but also for so far-unexplored "syndromic forms of PCD", taking advantage of data obtained through comparative genomic approaches between different species, ciliated or not.

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Ciliary Dyskinesia and Kartagener Syndrome, 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 1 inclusion and 1 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 7 Aug 2013. 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?

After DNA extraction,standard procedures for the identification of human gene mutations will be used for each gene tested in the study (time frame: At the inclusion visit). 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 NCT00783887, which also lists 37 linked publications.

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 7 Aug 2013.
