What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cryopreserved aortaProcedure or surgery

    After resection of the tracheal or bronchial lesion with standard surgical techniques, the airway gap is reconstructed with a segment of human cryopreserved (-80 celsius degree) aortic allograft, which was not matched by the ABO and leukocyte antigen systems. The anastomosis is performed with standard technique for airway anastomosis. An Ultraflex covered tracheobronchial stent is inserted to prevent collapse for the aortic graft.

Questions about this trial

What is this clinical trial studying?

A study testing Cryopreserved aorta in people with Trachea Diseases and Tracheal Stenosis, run by National Taiwan University Hospital at 1 site in Taiwan.

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 11 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: status not confirmed, as of the sponsor's last update on 11 May 2021. 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 Taiwan. 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?

Results are not available in the source record.

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?

90-day mortality (time frame: 90 days). 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 NCT04850742, which also lists 5 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 11 May 2021.
