RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Zoledronate may prevent bone loss and stop the growth of tumor cells in bone. It is not yet known whether monoclonal antibody is more effective than zoledronate in treating women who have breast cancer and bone metastases.
PURPOSE: Randomized phase I/II trial to compare the effectiveness of monoclonal antibody with that of zoledronate in treating women who have breast cancer and bone metastases.
OBJECTIVES:
OUTLINE: This is a randomized, double-blind, multicenter study. Patients are stratified according to average prestudy pain score on question 3 of a daily electronic telephone pain diary (less than 3 vs 3 or more) and prior bisphosphonate therapy (yes vs no). Patients are randomized to 1 of 4 treatment arms.
Patients keep a pain diary throughout study participation.
Patients are followed at 24 weeks.
PROJECTED ACCRUAL: A total of 72 patients (18 per treatment arm) will be accrued for this study.
DISEASE CHARACTERISTICS:
Radiographical evidence of at least 1 bone
Hormone receptor status:
PATIENT CHARACTERISTICS:
Age
Sex
Menopausal status
Performance status
Hematopoietic
Hepatic
Renal

PRIOR CONCURRENT THERAPY:
Biologic therapy
Chemotherapy
Endocrine therapy
Radiotherapy
Surgery

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
