About this study
Official title: A Phase IV, Multi-center, Open Label, Single Arm Clinical Trial to Evaluate the Relationship of Bone Remodeling Markers for Skeletal Complications in Metastatic Breast Cancer Patients

- time to skeletal-related events
- time to bone metastases progression
- overall survival
- the incidence of each adverse event including osteonecrosis

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
zoledronic acidDrug
Also called ZOMETA
Intravenous zoledronic acid 4mg over a minimum of 15 minutes in at least 100mls of calcium free infusion solution (0.9% sodium chloride or 5% glucose solution) every 4 weeks.
| Study group | Role | What they receive |
|---|---|---|
| Zoledronic acid | Experimental | Patients with advanced breast cancer with radiographic confirmation of bone metastases. This arm will be receiving zoledronic acid administration. The primary endpoint is to find the correlation between bone turnover markers and the frequency of skeletal-related-events for one year. Skeletal related events are defined as pathologic fractures, the need for radiation therapy, orthopaedic surgery, hypercalcemia of malignancy and spinal cord compression. A total of 237 patients will be included. Receives: Drug: zoledronic acid |
What is being measured
The primary outcome is the main question the study is designed to answer.
Urinary NTX and serum osteocalcin will be assessed at baseline, 3, 6, 9, and 12 months and when unexpected skeletal related events is detected.
Measured: one year

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing zoledronic acid in people with Metastatic Breast Cancer, run by Korean Breast Cancer Study Group at 1 site in South Korea.
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 12 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 17 Feb 2010. 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 South Korea. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Urinary NTX and serum osteocalcin will be assessed at baseline, 3, 6, 9, and 12 months and when unexpected skeletal related events is detected. (time frame: one year). 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 17 Feb 2010.
