  • Ages 18 to 99 years
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients with core breast biopsy that, on pathology review, demonstrates invasive breast cancer and are determined to need surgical excision of the lesion. All subtypes of invasive breast cancer will be enrolled. Core biopsy specimens of enrolled patients will be stained for RET by immunohistochemistry and scored, however, patients will not be excluded according to RET expression.
  • Female gender
  • Age >/= 18 years of age
  • ECOG performance status </= 2
  • Life expectancy of greater than 6 months
  • Ability and willingness to provide informed consent to participate in study

Who cannot join

  • Prolonged QT interval (QTc > 480 milliseconds) on screening EKG or congenital long QT syndrome
  • Any concomitant medications that are known to be associated with Torsades de Pointes or QT elongation (see appendix 2).
  • Hypertension not controlled by medical therapy (systolic BP greater than 160 millimeters of mercury [mmHg] or diastolic blood pressure great than 100 mmHg).
  • Patients taking metformin or digoxin.
  • History of arrhythmia (multifocal premature ventricular contractions, bigeminy, trigeminy, ventricular tachycardia), which is symptomatic or requires treatment (CTCAE Grade 3), symptomatic or uncontrolled atrial fibrillation despite treatment, or asymptomatic sustained ventricular tachycardia. Patients with atrial fibrillation controlled by medication are permitted.
  • Significant cardiac event (e.g., myocardial infarction), superior vena cava syndrome, New York Heart Association (NYHA) classification of heart disease ≥2 within 12 weeks, or presence of cardiac disease that in the opinion of the Investigator increases the risk of ventricular arrhythmia.

  • Previous exposure to Vandetanib
  • Previous enrollment or randomization in this study
  • Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and staff at UIHC).

About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Trial Investigating the Effect of Vandetanib on Cellular Markers of Proliferation and Apoptosis in Invasive Breast Cancer

The purpose of this project is to examine whether treatment with vandetanib has an effect on the tumor cells in breast cancer by examining tissue markers.

Read the detailed description

The purpose of this research study is to test whether vandetanib has an effect on tumor growth markers. Vandetanib is not approved by the FDA for use in treating breast cancer. This study will compare vandetanib to a placebo.

The proposed study is designed to determine the change in Ki-67 expression on paired breast cancer samples obtained before and after treatment with vandetanib. Other tumor markers including RET, TUNEL and phosphorylation specific levels of ERK1/2, AKT and mTOR will also be assessed on the paired samples.

Those who have a core biopsy of the breast which demonstrates invasive breast cancer and requires surgical excision of the lesion will be eligible for inclusion in the study. The tyrosine kinase inhibitor, vandetanib 300 mg, will be given once a day for 7-14 days prior to surgery. Following surgery, tissue markers would be analyzed on each of the paired samples, allowing for rapid assessment of in vivo response to TKI treatment.

What is being measured

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

  1. Percent Change From Baseline in Ki-67 Cells Observed 2 Weeks Post-treatment

    Pre- and post-treatment samples will be assessed by immunohistochemistry for positivity for Ki-67.

    Measured: 2 weeks

Secondary outcomes (1)
  1. Percent Change From Baseline in TUNEL Observed 2 Weeks Post-treatment

    Pre- and post-treatment samples will be assessed by immunohistochemistry for positivity for TUNEL.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Vandetanib in people with Invasive Breast Cancer, run by Ronald Weigel at 1 site in United States.

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 22 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 1 Nov 2021. 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 United States. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 1 Nov 2021). 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?

Percent Change From Baseline in Ki-67 Cells Observed 2 Weeks Post-treatment (time frame: 2 weeks). 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 1 Nov 2021.
