Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Do mesenchymal stem cells accelerate new bone formation in persistent non-unions treated with carrier plus in vitro expanded autologous BMSCs or carrier alone (control). Secondary aims were to analyze predictors of union in these patients and describe adverse events at final follow-up.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
35

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 76 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • An established non-union according to the US Food & Drug Administration criteria14.
  • Non-union following fracture of tibia or femur suitable for synthetic bone grafting.

Exclusion Criteria:

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: carrier plus BMSCs
carrier plus in vitro expanded autologous BMSCs
Biological: carrier plus in vitro expanded autologous BMSCs
The non-unions of fractures were stabilized with internal or external fixation devices. The non-union site was clearly exposed and decorticated to introduce sub-periosteal bone graft. Depending on the surgical approach, the site was partitioned in either medial/lateral or anterior/posterior sides. The contents of each universal container were mixed individually with a carrier by the surgeon, who was blinded to the contents of the container
PLACEBO_COMPARATOR: carrier alone (control).

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
Measure Description
Time Frame
Radiological assessment of new callus and fracture bridging
Time Frame: 12 months
The primary outcome measure was formation of new callus and cortical bridging, assessed from pre-operative and multiple post-operative radiographs and CT-scans up to 12 months. These images were divided into early (0-3 months) and late (9-12 months) groups. Non-unions were assessed from anonymized slides by four independent reviewers (two radiologists and two orthopedic surgeons) blinded to the side of cell insertion. Each slide had a pre-operative radiograph for comparison but no indication of time since surgery, and showed a medial/ lateral or an anterior/ posterior view depending on the surgical approach . At first, each reviewer indicated the side with largest callus and most cortical bridging pre-operatively. Then each reviewer examined subsequent radiographs to indicate the side with the largest increase in new callus and cortical bridging.
12 months

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
Measure Description
Time Frame
EQ-5D
Time Frame: 12 months
Change in EQ-5D index at 1 year was used as secondary outcome measures.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
