Primary Outcome Measures:
  • Number of Participants With Progression Free Survival (PFS) [ Time Frame: up to 18 months ] [ Designated as safety issue: No ]
    Complete Response (CR): disappearance of all target lesions. Any pathological lymph nodes (target or non-target) must have exhibited a reduction in short axis to < 10 mm. Partial Response (PR): at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum of diameters. Progressive Disease (PD): at least 20% increase in sum of diameters of target lesions taking as reference the smallest sum on study accompanied by an absolute increase of at least 5 mm or appearance of one or more new lesions. Stable Disease (SD): neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference smallest sum diameters. PFS is time from enrollment to date of first documented disease progression or death due to any cause. A participant is considered to be censored when data on time to event is missing due to a subject being lost to follow-up or non-occurrence of the outcome event before the completion of the trial.


Secondary Outcome Measures:
  • Percentage of Patients With Circulating Tumor Cell Levels of at Least 5 Per 7.5 mL of Peripheral Blood by Month [ Time Frame: Baseline, Month 1, 2, 4, 6, 9 and 18 ] [ Designated as safety issue: No ]
    Circulating tumor cells (CTCs) have been associated with poor patient prognosis and outcomes in patients receiving treatment for MBC. CTCs have been evaluated as a potential biomarker for predicting treatment effects and overall survival. Baseline was defined as the last predose measurement for patients who received any study drug and as the later of the screening visit or Visit 2 value for patients who did not receive the study drug. Percentage was calculated as the number of patients with CTC ≥5/7.5 mL against the number of patients with nonmissing CTC values (represented as 'n' in the categories).

  • Time to Progression (TTP) [ Time Frame: up to 18 months ] [ Designated as safety issue: No ]
    Time to progression is defined as the time from the date of enrollment to the date of first documented disease progression or death due to metastatic breast cancer.

  • Change From Baseline in Urine NTX by Month [ Time Frame: Baseline, Month 2, Month 4 ] [ Designated as safety issue: No ]
    NTX= N-telopeptide of type 1 collagen (nmol bce/mmol [nanomoles of bone collagen equivalents per millimole of creatinine]). Baseline was defined as the last predose measurement for patients who received any study drug and as the later of the screening visit or visit 2 value for patients who did not receive study drug.


Enrollment: 44

Study Completion Date: August 2012
Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Patients without bone metastases
Patients with no bone metastasis were randomized into a 1:1 ratio to standard therapy plus zoledronic acid 4mg IV Zoledronic acid administration monthly during Months 1-18.
Drug: Zoledronic acid
Patients with no bone metastasis (n=150) will receive Standard therapy plus Zoledronic acid administration 4 mg IV monthly during Months 1-18.
Other Names:
  • Zometa
  • bisphosphonates
  • CZOL446E
Experimental: Patients with bone metastases
Patients with bone metastasis received standard therapy + zoledronic acid for 18 months (discontinued upon disease progression/secondary malignancy)
Drug: Standard Therapy
Standard Therapy, including chemotherapy and hormonal therapy, was determined at the discretion of the investigator.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Written informed consent
  • Female patients (age ≥18 years)
  • HER2-negative metastatic breast cancer (stage IV)
  • Patients will be receiving chemotherapy or hormonal therapy
  • Patients with no bone metastasis and ≤1 prior treatments for metastatic breast cancer. Patients with newly diagnosed metastatic breast cancer may have received adjuvant or neoadjuvant chemotherapy as long as treatment was completed ≥12 months prior to relapse.
  • Asymptomatic brain metastasis is permitted if all of the following criteria are met:

    1. no sign of clinical progression or known progression of brain metastasis
    2. off steroids for at least 2 weeks prior to study enrollment
  • Stable renal function: two serum creatinine determinations of <3 mg/dL, obtained no less than 7 days apart (one value may be obtained within 6 weeks prior to Screening; the second must be obtained during Screening)
  • ECOG performance status of 0 or 1
  • Life expectancy of ≥ 6 months
  • Negative serum pregnancy test
  • Ability and willingness to comply with all study requirements

Exclusion Criteria:

  • Known hypersensitivity to zoledronic acid or other bisphosphonates
  • Patients with history of another malignancy within the last two years prior to study enrollment, except cured basal cell carcinoma of the skin or excised carcinoma in site of the cervix
  • Use of concurrent investigational agents is prohibited. Prior use of investigational agents is permitted if discontinued ≥30 days prior to Screening.
  • No prior therapy with an antiresorptive agent
  • Patients with active brain metastases or meningeal metastases
  • Current or recent (in the six months prior to initial study drug treatment) severe cardiovascular disease (defined as uncontrolled congestive heart failure), hypertension refractory to treatment, or poorly controlled Type I/II diabetes mellitus
