Trial summary

The goal of this study is to evaluate the bone regeneration capacity of BM-MSC (Bone marrow mesenchymal stromal cells), in patients with nonunion. BM-MSC cultured are seeded on a collagen scaffold, included into autologous platelet-rich plasma (PRP) clot, and implanted in the nonunion bone defect. Read more about this study

About this study

Official title: Treatment of Nonunion After Fractures (Pseudoartrosis) Using Mesenchymal Stromal Cells (MSCs)

The goal of this study is to evaluate the bone regeneration capacity of BM-MSC (Bone marrow mesenchymal stromal cells), in patients with nonunion. BM-MSC cultured are seeded on a collagen scaffold, included into autologous platelet-rich plasma (PRP) clot, and implanted in the nonunion bone defect.

Read the detailed description

Nonunion (pseudoarthrosis) is one of the most serious complications of bone fracture. Even though different treatments have been used to repair nonunion bone defects, most of them have limitations, like morbidities, limited supply, frequent treatment failure, and high cost.

Based on the knowledge that MSC have multipotential capacity of differentiation into bone, cartilage, fat, and endothelial cells, and also, play a key role in the process of bone formation and fracture repair. In this study, we evaluated the use the bone regeneration capacity of autologous or allogeneic BM-MSC, as a potential therapeutic strategy to induce formation of new bone tissue and fracture healing.

A bioengineering construct, constituted by MSCs and a collagen scaffold, is incorporated into platelet rich plasma (PRP) clot, wich is implanted at the nonunion site defect.

Being tested
Transplantation of autologous MSCs in nonunion fracture, Transplantation of allogeneic MSCs in nonunion fracture
Medical subject headings
Pseudarthrosis, Fractures, Ununited

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transplantation of autologous MSCs in nonunion fractureBiological

    At surgery, fibrotic tissue is removed from the nonunion sites. MSCs/Col/PRP clots are implanted in the site of nonunion.

    Patients received conventional orthopedic treatment as they needed (osteotomy, external and/or internal fixation systems, etc.)

  • Transplantation of allogeneic MSCs in nonunion fractureBiological

    At surgery, fibrotic tissue is removed from the nonunion sites. MSCs/Col/PRP clots are implanted in the site of nonunion.

    Patients received conventional orthopedic treatment as they needed (osteotomy, external and/or internal fixation systems, etc.)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Transplantation of autologous MSCs in nonunion fracture and Transplantation of allogeneic MSCs in nonunion fracture in people with Pseudoarthrosis of Bone and Pseudarthrosis, run by Instituto Venezolano de Investigaciones Cientificas at 1 site in Venezuela.

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 4 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 31 Oct 2023. 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 Venezuela. 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?

Clinical evaluation (time frame: Baseline, 1 and 7 days. 1, 2 and 6 months. 1 and 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06103396, which also lists 3 linked publications.

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 31 Oct 2023.
