Description

Inclusion criteria:

  • Is scheduled for breast biopsy due to a suspicious mass palpable or ≥1 cm on mammogram
  • Must be able to receive two doses of study medication 7 days apart prior to surgery
  • Has histologically confirmed invasive breast cancer with ER positive, ER and/or PR negative histology or triple negative (for ER, PR, HER-2) histology

  • Is able to swallow and retain oral medication

Exclusion criteria:

  • Has a concomitant medical condition that precludes adequate study treatment compliance or assessment, such as: a. Bleeding disorders that would increase risks of additional core biopsy for biomarkers b. Morbid obesity
  • Is currently receiving treatment with a medication on the prohibited medication list
  • Has allergy to benzamides or inactive components of study drug
  • Is participating in another clinical trial or has received another investigational agent within 30 days prior to informed consent
