Trial summary

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of simvastatin and anastrozole may stop cancer from forming, growing, or coming back in patients with invasive breast cancer, ductal carcinoma in situ, or a high risk of breast cancer.

About this study

Official title: A Trial Assessing the Effect of Simvastatin on the Pharmacokinetics of Anastrozole

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of simvastatin and anastrozole may stop cancer from forming, growing, or coming back in patients with invasive breast cancer, ductal carcinoma in situ, or a high risk of breast cancer.

PURPOSE: This phase II trial is studying how well giving simvastatin together with anastrozole works in treating postmenopausal women with invasive breast cancer, ductal carcinoma in situ, or a high risk of breast cancer.

Read the detailed description

OBJECTIVES:

Primary

  • Assess the effects of concurrent anastrozole and simvastatin on anastrozole's steady-state concentration in postmenopausal women with history of invasive breast cancer or ductal carcinoma in situ or at high risk for developing breast cancer.

Secondary

  • Study the effect of concurrent simvastatin and anastrozole on estrogen suppression in these patients.

OUTLINE: This is a pilot study.

Patients continue to receive oral anastrozole once daily (as prior to study entry). They also receive oral simvastatin once daily for 14-18 days in the absence of unacceptable toxicity or diagnosis of new or recurrent breast cancer.

Patients undergo blood sample collection at baseline and after study therapy for analysis of anastrozole and hormone (estradiol and estrogen) concentrations.

PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing anastrozole, simvastatin and pharmacological study in people with Breast Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins 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?

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 24 Jun 2013. 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. 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 24 Jun 2013). 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?

Change in Blood Concentrations (time frame: Baseline and 14 days). 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 24 Jun 2013.
