About this study

Official title: A Phase I Open-label Study to Assess the Safety, Tolerability and Potential Efficacy of a Novel Tracheal Replacement Consisting of a Tissue-engineered Decellularised Tracheal Scaffold With Seeded Autologous Mesenchymal Cells in Subjects With Severe Tracheal Stenosis or Malacia

This is a phase I study to evaluate the safety, efficacy and tolerability of a novel tracheal replacement therapy using cadaveric de-cellularised tracheal scaffold and patients' own mesenchymal cells isolated from a sample of their bone marrow in patients' who suffer from severe tracheal malacia or stenosis.

Read the detailed description

This is a phase I study to evaluate the safety, tolerability and potential efficacy of a novel tracheal replacement therapy using a cadaveric tracheal scaffold and patients own mesenchymal cells isolated from a sample of the patients own bone marrow. The study is aimed at treating patients who suffer from severe tracheal stenosis or malacia and for whom conventional therapies are no longer adequate. A total of 4 patients will be treated during the course of this study.

A hospital multi disciplinary team will review the medical history and available treatment options for all potential patients and recommend whether they are suitable for the study. Once patients are approved they will enter an 8 week screening period. During this period bone marrow from the patient will be harvested and the manufacturing of the final graft tissue will start. The manufacturing facility will use a cadaveric donated decellularised tracheal scaffold (supplied by the NHS blood and transplant body) and the patients own cells to make the final investigational product (graft).

The product will be surgically grafted into the patient in place of the damaged tracheal section. The graft will be supported by a stent for the first 6 months with replacements of this stent occurring at week 8 and week 16 post-surgical procedure. Hospitalization for a number of days will be required during this replacement steps. The patient will be followed frequently post surgery to capture any safety and efficacy measures. Long term follow up will continue up to 5 years post surgery.

    Measured: Up to 8 months post graft

Secondary outcomes (5)
  1. Efficacy: Post Implant Stent free period

    Measured: Up to 5 years post implant

  2. Efficacy: Post Implant Tracheostomy free period

    Absence of other surgical interventions

    Measured: Up to 5 years post implant

  3. Efficacy: Mean Airway Diameter evaluations as captured by CT scans

    Measured: Up to 5 years post implant

  4. Efficacy: Changes in lung function results using a combination of FEV1, FEF50 and PEFR results

    Measured: Up to 5 years post implant

  5. Number of treatment related AEs as assessed by CTCAE grading version 4.0

    Measured: Upto 5 years post implant

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Cadaveric decellularised tracheal scaffold seeded with autologous mesenchymal cells in people with Tracheomalacia and Tracheal Stenosis, run by Cell Therapy Catapult at 1 site in United Kingdom.

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 3 inclusion and 12 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: paused, as of the sponsor's last update on 29 Mar 2018. 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 United Kingdom. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

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?

Number of treatment related SAE's as assessed by CTCAE grades as defined in version 4.0 (time frame: Up to 8 months post graft). 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 29 Mar 2018.
