About this study

Official title: Randomized Phase 2 Study on the Relationship Between Circulating VEGF and Weekly or Every-four-week Zometa in Breast Cancer Patients With Bone Metastases

The primary objective of this study is to evaluate the effects of Zometa (zoledronic acid, 1 mg per week versus 4 mg every four weeks) on the circulating vascular endothelial growth factor (VEGF) levels in breast cancer patients with bone metastases. Sixty patients will be randomized into two groups.

Read the detailed description

The administration of Zometa in short intervals has been implied to be more potent in maximizing its antitumor and antiangiogenesis effects, while dosing every four weeks is an appropriate strategy for the prevention and management of bone metastases. This study was designed to explore the relationship between dosing of Zometa and level of circulating VEGF.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Zoledronic acid in people with Metastatic Breast Cancer and Bone Metastases, run by Fudan University 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 13 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: finished, as of the sponsor's last update on 14 Sep 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 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 combined 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.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Circulating VEGF levels in breast cancer patients with bone metastases (time frame: one month). 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 NCT00524849, 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 14 Sep 2010.
