Sunitinib in Treating Patients With Stage I, Stage II, or Stage III Breast Cancer Who Have Tumor Cells in the Bone Marrow

NCT ID: NCT00824538

Last Updated: 2018-04-05

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE2
• Total Enrollment: 13 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2009-02-28
• Study Completion Date: 2013-12-31

Brief Summary

RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

PURPOSE: This phase II trial is studying how well sunitinib works in treating patients with stage I, stage II, or stage III breast cancer who have tumor cells in the bone marrow.

Detailed Description

OBJECTIVES:

Primary

• To determine the effect of sunitinib malate on occult tumor cells (OTC) in the bone marrow of patients with high-risk stage I-III breast cancer.

Secondary

• To evaluate the number of patients who are able to tolerate this drug for 6 months and complete the study.
• To evaluate the toxicities of this drug in these patients.
• To evaluate the effects of this drug on OTC in peripheral blood.
• To evaluate correlative markers, including endothelial cells, soluble cKIT, and VEGF.
• To evaluate relapse-free and overall survival of patients treated with this drug.

OUTLINE: Patients receive oral sunitinib malate once daily for 6 months in the absence of disease progression or unacceptable toxicity.

Patients undergo bone marrow aspiration and peripheral blood sample collection at baseline and at 6 and 12 months. Bone marrow aspirate samples are analyzed by IHC and flow cytometry. Peripheral blood samples are analyzed for circulating tumor cells.

After completion of study treatment, patients are followed at 1 and 6 months.
