What is being measured

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

  1. Annual Overall Skeletal Morbidity Rate (SMR)

    The SMR was computed by summing all Skeletal Related Event(s) (SREs)which occurred during the observation period and dividing it by the ratio "days of observation period / 365.25", for each participant. SRE was defined as: pathologic bone fracture, spinal cord compression, surgery to bone both curative and prophylactic, radiation therapy to bone, or hypercalcemia of malignancy.

    SMR (years) = 365.25 x SMR(days) where SMR (days) = total number of SREs / total SRE risk period (days). Risk period for SMR was computed as the days from randomization date to the date of last visit.

    Measured: 12 months

Secondary outcomes (8)
  1. Percentage of Participants Experiencing Skeletal Related Event(s) (SREs)

    Skeletal Related Events (SREs) are defined as a:

    • pathologic bone fracture such as non-vertebral and vertebral compression fractures
    • spinal cord compression identified by positive diagnosis documented by X-ray evidence
    • surgery to bone both curative and prophylactic
    • radiation therapy to bone including palliative, therapeutic or prophylactic
    • hypercalcemia of malignancy, defined as a corrected serum calcium > 12 mg/dl (3.00 mmol/l) or a lower level of hypercalcemia which is symptomatic and which requires active treatment other than rehydration.

    Measured: 12 month

  2. Annual Incidence of Any Skeletal Related Events (SREs)

    Skeletal Related Events (SREs) are defined as a:

    • pathologic bone fracture such as non-vertebral and vertebral
    • spinal cord compression identified by X-rays evidence
    • surgery to bone both curative and prophylactic
    • radiation therapy to bone including palliative, therapeutic or prophylactic
    • hypercalcemia of malignancy, defined as a corrected serum calcium > 12 mg/dl (3.00 mmol/l) or a lower level of hypercalcemia which is symptomatic and which requires active treatment other than rehydration. Annual incidence for each SRE was computed in the same way as annual overall SMR.

    Measured: 12 months

  3. Median Time to First Skeletal Related Event(s) (SRE)

    Median Time to first skeletal related event (SRE) is defined as the time from randomization to the date of first occurrence of any SRE which includes at least one of the following: radiation therapy to bone, pathologic bone fracture, spinal cord compression, surgery to bone, and hypercalcemia of malignancy (HCM). Due to the few numbers of SRE, Kaplan-Meier estimate never reaches a failure probability >=25%; so median time, 25th and 75th percentiles are not determined.For this reason only the estimated percentage of patient SRE free are reported at each time point.

    Measured: 12 month

  4. Percentage of Participants Skeletal Related Event (SRE) Free

    Percentage of participants SRE free is defined as the Kaplan-Meier estimate of participants free of any Skeletal Related Events(SRE) at each time point.

    Skeletal Related Events (SREs) are:

    • pathologic bone fracture; non-vertebral and vertebral
    • spinal cord compression identified by X-rays
    • surgery to bone both curative and prophylactic
    • radiation therapy to bone (palliative, therapeutic or prophylactic)
    • hypercalcemia of malignancy, defined as a corrected serum calcium > 12 mg/dl (3.00 mmol/l) or a lower level which is symptomatic and requires treatment other than rehydration.

    Measured: 12 months

  5. Composite Bone Pain Score According to the Brief Pain Inventory (BPI) Questionnaire

    Bone pain was assessed by means of a pain score obtained using the Brief Pain Inventory (BPI) questionnaire. The BPI can produce three pain scores: worst pain, a composite pain score, and a pain interference score. The composite pain score, which is the average of questions 3, 4, 5 and 6 of the questionnaire was used in this study. Pain was rated on a scale of 0 (no pain) to 10 (pain as bad as you can imagine). The outcome is given as the median score for participants at baseline, and 3, 6, 9 and 12 months of treatment

    Measured: At Baseline, Month 3, Month 6, Month 9 and Month 12

  6. Evaluation of Pain According to Verbal Rating Scale (VRS) Based on Median Score Value

    Pain intensity at rest and on movement is rated by the patient by means of a validated 6-point Verbal Rating Scale (VRS) and refers to the pain which occurred during the last week before the assessment. Median score value is the median of all the observed scores (none=0, very mild=1, mild=2, moderate=3, severe=5 and very severe=6) at each time point.

    Measured: At Baseline, Month 3, Month 6, Month 9 and Month 12

  7. Use Of Analgesic Medications According to the Analgesic Score Scale

    The analgesic score used for this study is modified from the Radiation Therapy Oncology Group (RTOG) analgesic score scale. The scale represents type of medication administered from 0 to 4 where:

    0 = None

    1. = Minor analgesics (aspirin, NSAID, acetaminophen, propoxyphene, etc.)
    2. = Tranquilisers, antidepressants, muscle relaxants, and steroids
    3. = Mild narcotics (oxycodone, meperidine, codeine, etc.)
    4. = Strong narcotics (morphine, hydromorphone, etc.) The outcome is given a the median score for the participants at Baseline and 3, 6, 9 and 12 months of treatment

    Measured: At Baseline, Month 3, Month 6, Month 9 and Month 12

  8. Assessment of the Eastern Cooperative Oncology Group (ECOG) Performance Score

    ECOG Performance Score has 4 grades. 0 = Fully active, able to carry out all pre-disease activities; 1 = Restricted in strenuous activity but ambulatory and able to carry out work of light or sedentary nature; 2 = Ambulatory and capable of all self-care but unable to carry out work activities. Active about 50% of waking hours; 3 = Capable of limited self-care, confined to bed/chair more than 50% of waking hours; 4 = Completely disabled; cannot carry on self-care. Totally confined to bed/chair. Outcome is given as median score for participants at Baseline and 3, 6 , 9 and 12 months of treatment

    Measured: At Baseline, Month 3, Month 6, Month 9 and Month 12

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zoledronic acid in people with Breast Cancer With Bone Metastasis, run by Novartis Pharmaceuticals at 1 site in Italy.

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 11 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 11 Apr 2012. 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 Italy. 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?

Yes. Results are posted in the registry (first posted 4 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Annual Overall Skeletal Morbidity Rate (SMR) (time frame: 12 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 11 Apr 2012.
