Study of the Effect of Zoledronate on Local Recurrence After Surgical Treatment of Giant Cell Tumors of Bone Zométa
A Phase 1/2 study testing acid Zoledronic in people with Giant Cell Tumors of Bone, run by Nantes University Hospital at 1 site in France.
Trial summary
The giant cell tumor (GTC) is an aggressive benign bone tumor, growing at the metaphyseal-epiphyseal regions of long bones, especially around the knee and the distal radius.It is responsible for bony destruction in para-articular zone fracture and leading to the breakdown and destruction of the underlying joint.

About this study
Official title: Phase 2 Study of the Effect of Zoledronate on Local Recurrence After Surgical Treatment of Giant Cell Tumors of Bone
The giant cell tumor (GTC) is an aggressive benign bone tumor, growing at the metaphyseal-epiphyseal regions of long bones, especially around the knee and the distal radius.It is responsible for bony destruction in para-articular zone fracture and leading to the breakdown and destruction of the underlying joint.
Histologically, the tumor cell contains a contingent of monocytic cells round, a contingent of giant type cell of type osteoclastic responsible for bone resorption that accompanies these tumors and a contingent of lengthened cells fibroblast-like considered to be contingent tumor.

The treatment is exclusively surgical; or by resection of the lesion which takes away tumour and its environment, solution which, if it prevents local recurrence, imposes an important bony and articular reconstruction, always limited and deteriorating rapidly over time in these young patients; or by curettage of lesion, by "hollowing-out" of the bone, creating a hole which it will be necessary to fill up by a bony grafting or a substitute of the bone (cement). This last solution, if it preserves a better function, exposes at risk of local recurrence,putting into play the prognosis of articulation near, most often the knee.Despite different local adjuvants treatments used during surgical operation, after having curetted the cavity and before filling it up, the recidivism rates vary from 12 % to 41 % (average 25 %) in literature.
The beneficial effect of the adjuvants therapeutics suggests the concept broadly accepted by a tumoral microscopic residual at the origin of the local recidivism .Biphosphonates (BP) is molecules which settle in vivo on the hydroxyapatite of the bone; they inhibit the recruitment of the osteoclast forerunners and the activity of mature osteoclast. Besides, biphosphonates containing some nitrogen (N-BP), leads to the apoptose of mature osteoclast. These molecules also have a direct effect on tumor cells , causing apoptosis of neoplastic cells of myeloma, of breast cancer. Clinical controlled studies confirm the experimental data of N-BP. Two work also showed their effect on osteoclasts and stroma cells of tumours with giant cells but no clinical study assessed potential on the prevention of the local recurrence.
The investigators offer a study phase 2 of the effectiveness of N-BP (acid zoledronique) on the prevention of the local recurrence of tumours with primary huge cells after surgical treatment by curettage - filing by a surgeon referent in oncologic orthopedic surgery.

Local recurrence will be discussed in the presence or appearance on the radiographic and IRM monitoring of an osteolysis in the periphery of the cavity curetted, does not exist on the radio in post-operative with IRM signal abnormalities in the same location,taking the gadolinium. If in doubt, a new surgical biopsy will confirm or not the diagnosis of local recurrence

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing acid Zoledronic in people with Giant Cell Tumors of Bone, run by Nantes University Hospital at 1 site in France.
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 6 inclusion and 7 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 30 Aug 2013. 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 France. 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?
The study was stopped early. 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?
Decrease in the recurrence rate of GTC of the bone after surgery (efficacy). (time frame: 36 months). 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 Aug 2013.
