Biomarkers in Tissue Samples From Patients With Newly Diagnosed Breast Cancer Treated With Zoledronic Acid

April 28, 2020 updated by: City of Hope Medical Center

A Pilot Study of the Impact of a Single Dose of Zoledronic Acid on Biomarkers in Breast Cancer

This pilot clinical trial studies biomarkers in tissue samples from patients with newly diagnosed breast cancer treated with zoledronic acid (ZA). Studying samples of tumor tissue in the laboratory from patients receiving ZA may help doctors learn more about the effects of ZA on cells. It may also help doctors understand how well patients respond to treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate 14 tumor biomarkers of growth and metastasis (10 by microarray and 4 by RT-PCR) for change in response to ZA.

SECONDARY OBJECTIVES:

I. To evaluate 30 measures of immunologic function (by Luminex panel) for change in response to ZA a) after 48-72 hours and b) after 10-23 days.

II. To explore additional tumors biomarkers (approximately 20 by immunohistochemistry) for change in response to ZA.

OUTLINE: Patients receive zoledronic acid intravenously (IV) over 15 minutes on day 1. Patients then undergo planned definitive surgery (lumpectomy or mastectomy) on day 10-23. Tissue and blood samples from the initial biopsy and definitive surgery are collected to measure changes in biomarkers of tumor growth and metastasis, immunologic function, and the expression of genes important to breast cancer progression and metastasis.

After completion of study treatment, patients are followed up at 40-44 days.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

  • Estrogen receptor (ER)/progesterone receptor (PR) positive tumor (as confirmed by City of Hope Pathology Department if done on the outside) or
  • Biopsy proven ER/PR positive tumor
  • Ability to provide informed consent

Exclusion Criteria:

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Treatment (zoledronic acid)

Patients receive a single dose of zoledronic acid 4 mg IV over 15 minutes on day 1. Patients then undergo planned definitive surgery (lumpectomy or mastectomy) on day 10-23. Tissue and blood samples from the initial biopsy and definitive surgery are collected to measure changes in biomarkers of tumor growth and metastasis, immunologic function, and the expression of genes important to breast cancer progression and metastasis.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean (SE) Change From Pre-Treatment Baseline in (Log)pg/mL of Biomarker, by Time, Adjusted for Level at Baseline
Time Frame: "48-72 hrs" and "Surgery (10-23 days)"
After the trial's premature closure, no data were collected for the primary endpoints; however, data on 14 of 30 secondary endpoints were obtained and are summarized below. Serum level (pg/mL) per biomarker was log-transformed. Change from baseline over time was evaluated using a generalized linear mixed model where follow-up time was represented by terms for the sequence of post-baseline samples or for (log)day on study. To recognize regression to the mean across repeated samples, a term for biomarker level at baseline, with or without interaction by time, was included when it improved the model's fit to the observed data. With 14 biomarkers sampled twice after baseline, there were 28 evaluations of change in biomarker level with exposure to study drug. Therefore, to control the False Discovery Rate (FDR), only evaluations that maintained the study's FDR at no more than 5 percent were accepted as true.
