About this study

Official title: Zoledronic Acid-loaded Bone Cement as a Local Adjuvant Therapy for Giant Cell Bone Tumor After Intralesional Curettage: a Prospective, Multicenter, Single Blinded, Randomized Control Trial.

The purpose of this study is to investigate whether zoledronic acid-loaded bone cement (4mg ZOL+ gentamicin PMMA ) as adjuvant method can decrease local recurrence in patients with giant cell bone tumor following intralesional curettage surgery. The hypothesis is that patients with local administration of zoledronic acid to the bone cement has lower relapse rate compared those with traditional bone cement(gentamicin PMMA ).

Read the detailed description

The purpose of the clinical study is to investigate whether the local delivery of zoledronic acid (4mg ZOL-loaded gentamicin PMMA bone cement) as a surgical adjuvant can decrease the local recurrence rate of giant cell tumor (GCT) of bone. The investigators will also evaluate whether patients with zoledronic acid as a surgical adjuvant improves secondary outcomes, including function (MSTS and TESS), surgery related complications (henderson's failure mode) and ZOL-related complications.

What participants receive

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

  • 4mg ZOL loaded gentamicin PMMAProcedure or surgery

    During surgery, 4mg ZOL will be mixed with gentamicin (1000mg) PMMA cement (40g) by surgeon under sterile conditions to prepare ZOL loaded bone cement, and then it will be filled into the bony defects of the patient where the lesion has been removed after intralesional curettage.

  • gentamicin PMMAProcedure or surgery

    During surgery, gentamicin (1000mg) PMMA (40g) was prepared by surgeon under sterile conditions and will be filled into the bony defects of the patient where the lesion has been removed after intralesional curettage.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. time to first local recurrence

    Time to first local recurrence will be reported during postoperative 18-month follow up period

    Measured: All patients will be followed for this endpoint until 18 months postoperatively

Secondary outcomes (4)
  1. MSTS score

    The Musculoskeletal Tumor Society (MSTS) scoring system is a disease-specific instrument to determine the physical and mental health for patients underwent limb-salvage surgery after tumor resection and is a validated and well-accepted functional scoring system used in orthopaedic oncology research

    Measured: Doctors will be responsible in filling this questionnaire 3 months, 9 months, 12 months, 18 months postoperatively during patients' follow up

  2. TESS score

    The Toronto Extremity Salvage Score (TESS) is a physical disability measure developed specifically for patients undergoing surgery for extremity tumours and has been shown to have superior measurement properties compared with other commonly used sc

    Measured: Patients will be asked to fill this survey 3 months, 9 months, 12 months, 18 months postoperatively

  3. postoperative complication

    Including wound healing problem, mechanical failure, infection and any tumor progression issues

    Measured: Patients will be asked to report any complication 1 month, 3 months, 6 months, 9 months, 12 months, 18 months postoperatively during follow up

  4. Potential ZOL-related complications

    Patients will be followed for atypical bone fractures and avascular necrosis (AVN) of jaw, one of the most severe complication of ZOL

    Measured: Patients will be followed to report any complication 1 month, 3 months, 6 months, 9 months, 12 months, 18 months postoperatively.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 4mg ZOL loaded gentamicin PMMA and gentamicin PMMA in people with Giant Cell Tumor of Bone, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 1 site in China.

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 5 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: looking for participants now, as of the sponsor's last update on 15 Mar 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 China. 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 phase mean?

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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Meng Liu, MD (13515711791, liumeng80@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

time to first local recurrence (time frame: All patients will be followed for this endpoint until 18 months postoperatively). 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 15 Mar 2023.
