Brief Summary:

RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors identify biomarkers related to cancer. Riluzole may help slow the growth of tumor cells.

PURPOSE: This phase I trial is studying riluzole in women with stage I, stage II, or stage IIIA breast cancer.


Condition or disease Intervention/treatment Phase
Breast Cancer Drug: riluzole Genetic: polymorphism analysis Procedure: axillary lymph node biopsy Procedure: digital image analysis Procedure: needle biopsy Procedure: sentinel lymph node biopsy Procedure: therapeutic conventional surgery Phase 1

Detailed Description:

OBJECTIVES:

Primary

  • To evaluate the effects of glutamate receptor blockade with riluzole on cellular pathways important in the genesis and progression of disease in women with stage I-IIIA breast cancer by examining components of the mGluR1 signaling pathway in the pre- and post-treatment tumor samples to determine if glutamate blockade affects signaling through this pathway.

Secondary

  • To determine whether treatment with riluzole affects the proliferation and apoptosis in a manner suggesting a potential for therapeutic effectiveness.
  • To determine whether treatment with riluzole causes objectively measurable tumor shrinkage.

OUTLINE: Patients receive oral riluzole twice daily on days -14 to 0. Approximately 12 hours after completion of riluzole therapy patients undergo standard surgery (i.e., partial or total mastectomy) along with sentinel lymph node biopsy (for patients with node-negative disease) or full axillary dissection (for patients with node-positive disease) on day 0.

Patients undergo 3-dimensional image assessment at pre- and post-treatment by Computerized Ultrasound Risk Evaluation (C.U.R.E.).

Patients undergo core needle biopsy at baseline and during surgery for biomarker analysis (e.g., mGluR1) by IHC, western blotting, and RT-PCR. Blood samples are collected for GRM1 polymorphism analysis.

After completion of study treatment, patients are followed every 6 months for 1 year and then according to standard-of-care thereafter.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Inhibition of downstream targets of the mGluR1 signaling cascade, specifically downregulation of PLCβ activity [ Time Frame: Pre and Post-treatment with RILUTEK® (riluzole) administration ]
  2. Downregulation of phosphorylated ERK1/2 [ Time Frame: Pre and Post treatment with RILUTEK® (riluzole) administration: ]

Secondary Outcome Measures :
  1. Measures of proliferation, specifically mitotic rate and expression of Ki-67 [ Time Frame: Pre and Post treatment with RILUTEK® (riluzole) administration: ]
  2. Measures of apoptosis, specifically levels of poly(ADP-ribose) polymerase (PAPR) cleavage and caspase III activity [ Time Frame: Pre and Post treatment with RILUTEK® (riluzole) administration: ]
