Condition Intervention Phase
Breast Cancer Drug: sorafenib Phase 2

Study Type: Interventional

Primary Outcome Measures:
  • Response Rate [ Time Frame: 12 weeks after treatment & 8 weeks after initial documentation of response ]
    Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR. Patients were followed monthly for clinical and toxicity evaluation. Disease response by RECIST criteria v1.0 was assessed after 3 months by appropriate scans and these were obtained every 2 months thereafter until progression.


Secondary Outcome Measures:
  • Time to Progression [ Time Frame: continuously ]
  • Clinical Benefit Rate [ Time Frame: 24 weeks ]
    Clinical benefit rate is defined as complete response, partial response, or stable disease (CR/PR/SD) as measured by Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for a minimum of at least 24 weeks.


Enrollment: 11
Study Start Date: October 2007
Study Completion Date: January 2015
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Sorafenib & Endocrine Therapy
Sorafenib & Endocrine Therapy
Drug: sorafenib
400 mg PO (orally) twice daily for 12 months from study enrollment or until disease progression, whichever occurs first.
Other Name: Nexavar

Detailed Description:
A pilot Phase II study adding sorafenib to endocrine therapy in 11 patients with metastatic estrogen receptor-positive breast cancer was conducted. Primary end point was response by Response Evaluation Criteria in Solid Tumors (RECIST) after 3 months of sorafenib. Secondary end points included safety, time to progression and biomarker modulation. The study closed early owing to slow accrual.

  • Estrogen receptor and/or Progesterone positive disease.
  • Metastatic or locally advanced disease.
  • Patients on a preexisting endocrine agent for at least 3 months before enrollment.
  • Have residual measurable disease after

    1. maximal response to endocrine therapy or

  • Major surgery, open biopsy or significant traumatic injury within the 4 weeks prior to the first dose of the study drug.
  • Pulmonary hemorrhage/bleeding event ≥ Common Toxicity Criteria for Adverse Effects (CTCAE) Grade 2 within the 4 weeks prior to the first dose of study drug.
  • Pregnancy
  • Any condition that impairs patient's ability to swallow whole pills.
  • Documented malabsorption problem.
