Trial summary

The main objective is to establish that a new technique of amyloidosis typing by Proteomics (based on nanoLC-MS/MS mass spectrometry) allows typing in > 90% of observations in patients whose Amyloidosis is reported to have failed typing (impossible typing, uncertain or inconsistent) with the traditional… Read more about this study

About this study

The main objective is to establish that a new technique of amyloidosis typing by Proteomics (based on nanoLC-MS/MS mass spectrometry) allows typing in > 90% of observations in patients whose Amyloidosis is reported to have failed typing (impossible typing, uncertain or inconsistent) with the traditional anatomopathological approach, and this in a cohort of 40 patients identified consecutively in the Department of pathological anatomy and cytology of the University Hospital of Toulouse and included prospectively.

Questions about this trial

What is this clinical trial studying?

A study testing Amyloidosis typing using mass spectrometry-based proteomics in people with Amyloidosis, run by University Hospital, Toulouse 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 6 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 12 Jul 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.

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?

Amyloidosis typing (time frame: Day 0). 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 NCT03984721, which also lists 2 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 12 Jul 2023.
