About this study

Official title: A Randomized, Parallel-Group (Autogenous EVPOME Versus AlloDerm Without Incorporation of Keratinocytes) Study in Subjects Reconstructed With Large Defect Mandibular Resection in Need of Vestibuloplasty for Dental Rehabilitation

The purpose of this study is to compare the safety and effectiveness of performing oral reconstructive surgeries using either AlloDerm, a product commonly used for this purpose, or AlloDerm that has been overlaid with the subject's oral mucosal cells and developed into a type of graft that is called an ex vivo produced oral mucosal equivalent, EVPOME.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Graft Contracture

    During surgery, after preparation of the recipient bed, the recipient bed and the graft will be measured for the maximum distance between non-resorbable sutures placed at the margins of the graft. Post-surgical measurements of the graft site will be taken at visits 5, 6, 7, and 8 and compared to original graft size to assess percentage of graft contracture.

    Measured: 2-24 weeks

Secondary outcomes (2)
  1. Degree of Epithelialized Tissue

    Degree of epithelialized mucosa will be assessed by biopsy taken at the geometric center of the graft at week 4 s/p grafting. The biopsy will be evaluated by routine histology for the presence of an intact and stratified keratinized epithelial layer and by immunohistochemistry (IHC) for microvessel vascular ingrowth into the dermis/dermal matrix (AlloDerm).

    Measured: 4 weeks after surgery

  2. Laser Doppler Flowmetry (LDF)

    LDF measurements will be used to assess graft blood flow (tissue perfusion of the grafts). The LDF measures will also be compared with the immunohistochemistry (IHC) results seen on the biopsy to determine the relationship between the flood flow and degree of microvessel infiltration into the dermis/dermal matrix (AlloDerm) based on the two measures.

    Measured: Visit 1 and 2 and 4 weeks after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AlloDerm and EVPOME in people with Mandibular Injuries, run by Stephen E. Feinberg at 1 site in United States.

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 9 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: stopped early, as of the sponsor's last update on 22 Nov 2017. 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 States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study was stopped early (reason given: Loss of cGMP facility to manufacture product used in clinical trial.). 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?

Percent Graft Contracture (time frame: 2-24 weeks). 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 22 Nov 2017.
