About this study

Official title: Effectiveness and Safety of Method of Maxilla Alveolar Process Reconstruction Using Tissue Engineered Construction Based on a Synthetic Tricalcium Phosphate and Autologous Multipotent Mesenchymal Stromal Cells Obtained From Oral Mucosa

Autologous MMSCs will be isolated from oral mucosa biopsy sample and expanded in vitro.Tissue engineered construction will be created using synthetic tricalcium phosphate and autologous MMSCs. Patients will undergo sinus lift procedure with implantation of created tissue-engineered construction. This is a single arm study with no control. All patients receive cell therapy.

Read the detailed description

Patients with verified diagnosis partially edentulous maxilla and alveolar bone atrophy will undergo oral mucosa biopsy and autologous MMSCs will be derived and expanded in vitro during 3-4 weeks. After that tissue engineered construction will be created using synthetic tricalcium phosphate and autologous MMSCs. Patients will undergo sinus lift procedure with implantation of created tissue-engineered construction. Six months later patients will undergo dental implant installation. Biopsy of bone tissue at the site of sinus lift will be performed as a part of dental implant installation with subsequent histological analysis of bone specimen.

What is being measured

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

  1. Number of serious adverse events (SAEs) and serious adverse reactions (SARs)

    Measured: 1 week after treatment

Secondary outcomes (3)
  1. Quality of life monitoring

    Quality of life estimated by validated questionnaire: the Short Form (36) Health Survey (SF-36).

    Measured: up to 24 weeks after treatment

  2. Changes in bone tissue volume

    Changes in volume and density of bone tissue at the site of manipulation and newly formed bone micro-architecture assessed by cone beam CT (morphometrical analysis using Hounsfield unit measurements)

    Measured: up to 24 weeks after treatment

  3. Correlation of morphometrical analysis using cone beam CT scan with absolute value of the newly formed bone

    Biopsy of bone tissue at the site of sinus lift will be performed as a part of dental implant installation. Bone sample will be evaluated histologically: absolute value of the newly formed bone will be calculated using histomorphometrical analysis.

    Measured: 24 weeks after treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Oral mucosa biopsy, Sinus lift with implantation of tissue engineered construction and Dental implant in people with Partially Edentulous Maxilla and Alveolar Bone Atrophy, run by Central Clinical Hospital w/Outpatient Health Center of Business Administration for the President of Russian Federation at 2 sites in Russia.

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 18 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: status not confirmed, as of the sponsor's last update on 30 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Russia. 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 combined 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.

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?

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 serious adverse events (SAEs) and serious adverse reactions (SARs) (time frame: 1 week after treatment). 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 30 Nov 2016.
