About this study

Official title: Multicenter, Open-label, Randomized Phase III Trial for Administration of Zoledronate to Breast Cancer Metastatic Patients With Non-symptomatic Bone Lesions

This is an open-label, randomized, multicenter phase III trial to assess the efficacy of early administration of zoledronate versus observation in delaying bone-related symptoms in metastatic breast cancer patients.

Read the detailed description

Patients will be randomised to receive 4 mg zoledronate every 3-4 weeks versus observation until bone-related symptoms appear, or up to 12 months. One hundred twelve patients per treatment arm will be enrolled in the study.

Once bone-related symptoms appear, study participation is over. During the study, the following will be assessed:

  • quality of life,
  • performance status,
  • pain rating,
  • analgesic administration and
  • adverse events The principal objective is the delay in bone-related symptoms in those patients with early zoledronate administration.

What participants receive

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

Study groups in NCT00130494
Study groupRoleWhat they receive
Arm A: Zoledronic acid 4 mgExperimentalZoledronate 4 mg every 3 or 4 weeks. This arm will receive study treatment from the time of entry into the trial, until the appearance of the symptoms of bone metastases (or a maximum period of 12 months, whichever occurs first).
Receives: Drug: Zoledronic acid
Arm B: ObservationNo interventionPatients will not receive any treatment with bisphosphonates until the time of onset of symptoms (or a maximum period of 12 months, whichever occurs sooner).

What is being measured

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

  1. Time to first bone metastases

    The main variable of evaluation is the time until the appearance of first bone metastases.

    Measured: Up to disease progression

Secondary outcomes (2)
  1. Quality of life per treatment arm

    Quality of Life (QoL) will be measured with Short Form (SF)-36 questionnaire and Short questionnaire for the evaluation of pain since baseline visit and during all treatment period delivered to the patient before the start of each visit.

    Measured: Up to disease progression

  2. The Number of Participants Who Experienced Adverse Events (AE)

    Safety will be assessed by standard clinical and laboratory tests. Adverse events grade will be defined by the NCI CTCAE.

    Measured: Through study treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zoledronic acid in people with Breast Cancer and Neoplasm Metastasis, run by Spanish Breast Cancer Research Group at 1 site in Spain.

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 10 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 16 Apr 2019. 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 Spain. 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 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 was stopped early (reason given: Low recruitment). 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?

Time to first bone metastases (time frame: Up to disease progression). 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 16 Apr 2019; AzTrials last refreshed its copy on 8 Nov 2026.
