November 29, 2016 updated by: Central Clinical Hospital w/Outpatient Health Center of Business Administration for the President of Russian Federation

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Number of serious adverse events (SAEs) and serious adverse reactions (SARs)
Time Frame: 1 week after treatment
1 week after treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame: up to 24 weeks after treatment
Quality of life estimated by validated questionnaire: the Short Form (36) Health Survey (SF-36).
