Trial summary

Mitochondrial diseases are the most frequent metabolic diseases (2.5 persons among 10 000) and are clinically heterogeneous making diagnosis particularly challenging for clinicians. Molecular analysis of mitochondrial DNA (mtDNA) is a critical step in diagnosis and genetic counselling of respiratory chain defects. Read more about this study

About this study

Official title: Economic and Medical Evaluation of the Whole Mitochondrial DNA Screening by Surveyor and Mitochips Techniques.

Mitochondrial diseases are the most frequent metabolic diseases (2.5 persons among 10 000) and are clinically heterogeneous making diagnosis particularly challenging for clinicians.

Molecular analysis of mitochondrial DNA (mtDNA) is a critical step in diagnosis and genetic counselling of respiratory chain defects. DNA sequencing remains the gold standard but it is time-consuming and fails to detect mutations that may be present at a low heteroplasmic level (20% or below); therefore the diagnosis is yet based on the detection of a few number of pathogenic mutations.

The present study aims to evaluate the benefit and the cost of a diagnosis strategy based on the combined use of 2 techniques named "Surveyor Nuclease" and "Mitochip". Surveyor nuclease is a mismatch-specific DNA endonuclease that will be used for screening the entire mtDNA in order to identify heteroplasmic mutations. In absence of any identified mutation, another technique based on the use an oligonucleotide sequencing microarray (MitoChip) will be performed for the identification of homoplasmic mutations. Mitochip is an array-based sequencing platform for rapid and high-throughput analysis of mitochondrial DNA.

The economical study will compare the cost of these techniques to the standard diagnosis method in term of direct and indirect costs

Questions about this trial

What is this clinical trial studying?

An observational study of Mitochondrial Disease, run by Centre Hospitalier Universitaire de Nice 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 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: finished, as of the sponsor's last update on 18 Dec 2012. 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?

Evaluation of the benefit and the cost of a mitochondrial disease diagnosis strategy based on the combined use of 2 techniques named "Surveyor Nuclease" and "Mitochip" (time frame: 2 years). 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 18 Dec 2012.
