This is an interventional treatment trial for Breast Cancer focused on measuring triple-negative breast cancer Read More

Inclusion Criteria:

• Invasive carcinoma of the breast

• HER2 non-overexpressing status documented as:
• FISH ratio of less than 2.0, OR
• IHC staining of 0 or 1+
• No evidence of distant metastatic disease. Patients with regional lymph node involvement are eligible.
• >18 years old
• Female
• No prior treatment for the disease under study
• No prior treatment within 5 years for any other cancer including chemotherapy, surgery (except for diagnostic biopsy), radiotherapy, hormonal therapy, or investigational agents, unless curative treatment of non-melanoma skin-cancer or in-situ cancer
• Able to understand and sign an informed consent (or have a legal representative who is able to do so)
• Clinically or radiologically measureable disease in the breast after diagnostic biopsy, defined as longest diameter greater than or equal to 2cm
• Willing to undergo three mandatory core biopsies after diagnosis to obtain tissue for biologic expression profiling.
• An Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1
• Adequate bone marrow reserves as evidenced by:
• Leukocytes > 3,000/μL
• Absolute neutrophil count (ANC) > 1,500/μL without the use of hematopoietic growth factors,
• Platelet count > 100,000/μL, and
• Hemoglobin > 9 g/dL
• Adequate hepatic function as evidenced by:
• Serum total bilirubin within institutional normal limits
• Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase less than or equal to 2.5 × ULN
• Adequate renal function as evidenced by a serum creatinine within ULN or creatinine clearance > 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
• Eligible for treatment with paclitaxel, doxorubicin and cyclophosphamide
• If of childbearing potential, are willing to abstain from sexual intercourse or to use an effective form of contraception (e.g., a double-barrier method) during the study and for 90 days following the last dose of ganetespib

Exclusion Criteria:

• • Patients may not be receiving any other investigational agents.

  • Patients may not have a known hypersensitivity to any of the components of ganetespib
  • Patients may not have a history of severe allergic reactions to paclitaxel or other drugs formulated in Cremaphor® EL.
  • Patients with a QTc > 470 ms, a family history of long QT Syndrome, and those on medications known to cause Torsades de Pointes will be excluded from the study.
  • Patients may not have an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Patients may not have New York Heart Association (NYHA) Class III or IV congestive heart failure or left ventricular ejection fraction (LVEF) < 50%.
  • As patients with immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy, HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study.
  • Patients may not have a need for chronic systemic steroid therapy
  • Patients may not be pregnant or breastfeeding
