Osteonecrosis of the Femoral HeadPhase 3NCT01529008
Study on Autologous Osteoblastic Cells Implantation to Early Stage Osteonecrosis of the Femoral Head
A Phase 3 study testing Core decompression/PREOB® implantation in people with Osteonecrosis of the Femoral Head, run by Bone Therapeutics S.A.
Trial summary
Non-traumatic osteonecrosis is a painful disorder of the hip characterized by a necrosis of the osteomedullary tissue, which leads to subchondral bone collapse and joint destruction. Core decompression is currently the treatment of choice for early stage osteonecrosis of the femoral head. Read more about this study

About this study
Official title: Phase 3, Pivotal, Multicentre, Randomised, Double-blind Controlled Study to Evaluate the Efficacy and Safety of Autologous Osteoblastic Cells (PREOB®) Implantation in Early Stage Non Traumatic Osteonecrosis of the Femoral Head
Non-traumatic osteonecrosis is a painful disorder of the hip characterized by a necrosis of the osteomedullary tissue, which leads to subchondral bone collapse and joint destruction. Core decompression is currently the treatment of choice for early stage osteonecrosis of the femoral head. This method consists in decompressing the rigid intra-osseous chamber to promote revascularization, thus halting progression of the disease and stimulating repair. Still this treatment remains highly controversial, since the success rates of the first studies have not been repeated.
The exact pathology mechanisms involved in osteonecrosis have not yet be fully elucidated. Several hypotheses have been evoked, including fat embolism, trabecular bone microfractures, microvascular tamponade and, more recently, impaired bone and/or mesenchymal cells recruitment.

Three studies have indicated the potential clinical benefits of cell-based approaches for the treatment of osteonecrosis (Hernigou 1997, Hernigou \& Beaujean 2002, Gangji et al. 2004). This is on the basis of these observations that a proprietary population of autologous osteoblastic cells (PREOB®) has been developed.
This Phase 3 study aims at demonstrating the efficacy and safety of PREOB® in the treatment of early stage osteonecrosis of the femoral head. More specifically, the purpose of the study is to demonstrate that core decompression/PREOB® implantation into the necrotic lesion is superior to core decompression/placebo implantation in relieving hip symptoms and halting (or reverting) radiological progression of the disease.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Core decompression/PREOB® implantation in people with Osteonecrosis of the Femoral Head, run by Bone Therapeutics S.A.
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 8 inclusion and 33 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 24 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 24 Jun 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Percentage of Treatment Responders (time frame: 24 months). 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 NCT01529008, which also lists 1 linked publication.
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 24 Jun 2022.
