Clinical trial: Tivantinib in Treating Patients With Recurrent or Metastatic Breast Cancer

Summary: This phase II trial studies how well tivantinib works in treating patients with recurrent or metastatic breast cancer. Tivantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description: PRIMARY OBJECTIVES:
  I. To evaluate the activity of tivantinib (ARQ-197) as defined by 6-month progression-free survival (PFS) of participants with triple-negative metastatic breast cancer.
  SECONDARY OBJECTIVES:
  I. To evaluate objective response based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
  II. To evaluate c-Met and phospho c-Met expression in archival tumor tissue. (Exploratory) III. To evaluate the incidence of c-Met-positive circulating tumor cells at baseline. (Exploratory) IV. To evaluate the effect of ARQ-197 on serum markers relevant to c-Met pathway (hepatocyte growth factor [HGF] and vascular endothelial growth factor [VEGF]). (Exploratory) V. To evaluate phosphatase and tensin homolog (PTEN) loss and PI3K mutations in archival tumor tissue. (Exploratory) VI. To evaluate proportion of participants with basal-like breast cancer. (Exploratory)
  OUTLINE: This is a multicenter study.
  Patients receive tivantinib orally (PO) twice daily (BID) on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo blood sample collection at baseline and periodically during study for c-Met expression, relevant markers (HGF and VEGF), PTEN loss, and PI3K mutation analysis by fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC). Archived tumor tissue samples are also analyzed.
  After completion of study treatment, patients are followed up every 6 months.

  -  Serum creatinine =< 1.5 times ULN OR creatinine clearance >= 60 mL/min/1.73 m^2 for participants with creatinine levels above institutional normal
  -  Either the primary tumor and/or the metastasis must be triple-negative; the invasive tumor must be hormone-receptor poor, defined as estrogen-receptor negative (ER-) and progesterone-receptor negative (PR-), or staining < 10% by immunohistochemistry (IHC)
  -  Human epidermal growth factor receptor 2 (HER2) status: the invasive tumor must be HER2-negative, defined as 0 or 1+ by IHC, or FISH < 2.0
  -  Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) during the study and for 90 days after the last investigational drug dose received
  -  Female subjects of childbearing potential must have a negative serum pregnancy test within 21 days of cycle 1 day 1
  -  Participants on bisphosphonates may continue receiving bisphosphonate therapy during study treatment; bisphosphonate therapy may also be initiated on study treatment if needed
  -  Confirmed availability of formalin-fixed, paraffin-embedded (FFPE) tumor tissue

  -  Participants who are receiving any other investigational agents
  -  Known brain metastases that are untreated, symptomatic, or require therapy to control symptoms
  -  Participants with a history of treated central nervous system (CNS) metastases are eligible
  -  Treated brain metastases are defined as those having no evidence of progression or hemorrhage for >= 2 months after treatment, and no ongoing requirement for corticosteroids, as ascertained by clinical examination and brain imaging (magnetic resonance imaging or computed tomography [CT] scan) during the screening period
  -  Treatment for brain metastases may include whole-brain radiotherapy, radiosurgery, or a combination as deemed appropriate by the treating physician
  -  Participants may be taking anti-convulsant medications, which must be non-enzyme-inducing anti-epileptic drugs
