Primary Outcome Measures:
  • Abscopal response rate [ Time Frame: up to 20 weeks ] [ Designated as safety issue: No ]
    Defined as the percentage of patients who have responses (complete or partial) outside the irradiated lesions. The abscopal response is assessed at 15 weeks, and confirmed minimum 4 weeks later. The abscopal response is evaluated based on immune-related response criteria (irRC) (Wolchok et al, 2009).

Enrollment: 24
Study Start Date: July 2011
Estimated Study Completion Date: March 2016
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1 (Fresolimumab 1 mg/kg)
Fresolimumab is administered intravenously (i.v.) at a dose of 1 mg/kg on day 1 of weeks 0, 3, 6, 9 & 12 and radiation administered at 7.5 Gy/fraction in 3 fractions during weeks 1 (to lesion 1) and 7 (to lesion 2).
Drug: Fresolimumab
Other Name: GC1008
Radiation: Radiation Therapy
Experimental: Arm 2 (Fresolimumab 10 mg/kg)
Fresolimumab is administered intravenously (i.v.) at a dose of 10 mg/kg on day 1 of weeks 0, 3, 6, 9 & 12 and radiation administered at 7.5 Gy/fraction in 3 fractions during weeks 1 (to lesion 1) and 7 (to lesion 2).
Drug: Fresolimumab
Other Name: GC1008
Radiation: Radiation Therapy


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Biopsy-proven breast cancer, metastatic (persistent or recurrent).
  • Failed ≥1 line of therapy (endocrine or chemotherapy) for metastatic disease.
  • Min. 3 distinct metastatic sites, at least one measurable lesion which is at least 1 cm or larger in largest diameter.
  • Must be ≥4 weeks since all of the following treatments (recovered from toxicity of prior treatment to ≤Grade 1, excluding alopecia):

    • major surgery;
    • radiotherapy;
    • chemotherapy (≥6 weeks since therapy if a nitrosourea, mitomycin, or monoclonal antibodies such as bevacizumab);
    • immunotherapy;
    • biotherapy/targeted therapies.
  • >18 years of age.
  • Life expectancy >6 months.
  • Eastern Cooperative Oncology Group (ECOG) status 0 or 1.
  • Adequate organ function including:

    • Hemoglobin ≥10.0g/dL, absolute neutrophil count (ANC) ≥1,500/mm3, and platelets ≥100,000/mm3.
    • Hepatic: Serum total bilirubin ≤1.5x upper limit of normal (ULN) (Patients with Gilbert's Disease may be included if total bilirubin is ≤3.0mg/dL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) ≤2.5xULN. If patient has known liver metastases, ALT and/or AST ≤5xULN are allowed.
    • Renal: creatinine clearance ≥60mL/min.
    • Prothrombin (PT) and partial thromboplastin times (PTT) <ULN.
  • Negative for hepatitis viruses B and C unless consistent with prior vaccination or prior infection with full recovery.
  • Patients of childbearing potential must agree to use effective contraception while on study, and for ≥3 months after last treatment.
  • Understand and sign written informed consent document. No consent by durable power of attorney.

Exclusion Criteria:

  • Second malignancy - unless following curative intent therapy, has been disease free for ≥2 years with probability of recurrence <5%. Curatively treated early-stage squamous cell carcinoma of the skin, basal cell carcinoma of the skin, or cervical intraepithelial neoplasia (CIN) are allowed.
  • Concurrent cancer therapy.
  • Uncontrolled central nervous system (CNS) metastases, meningeal carcinomatosis, malignant seizures, or disease that causes or threatens neurologic compromise (e.g. unstable vertebral metastases).
  • History of ascites or pleural effusions, unless successfully treated.
  • Organ transplant, including allogeneic bone marrow transplant.
  • Immunosuppressive therapy including:

    • Systemic corticosteroid therapy, including replacement therapy for hypoadrenalism. Inhaled or topical corticosteroids are allowed (if therapy is <5 days and is limited to systemic steroids as antiemetics);
    • Cyclosporine A, tacrolimus, or sirolimus.
  • Investigational agents within 4 weeks prior to study enrollment (≥6 weeks if treatment was long-acting agent such as monoclonal antibody).
  • Significant or uncontrolled medical illness, e.g. congestive heart failure (CHF), myocardial infarction, symptomatic coronary artery disease, significant ventricular arrhythmias within the last 6 months, or significant pulmonary dysfunction. Patients with remote history of asthma or active mild asthma may participate.
  • Active infection, including unexplained fever (>38.5°C).
  • Systemic autoimmune disease (e.g. systemic lupus erythematosus, active rheumatoid arthritis).
  • Known allergy to any component of GC1008.
  • Active thrombophlebitis, thromboembolism, hypercoagulability states, bleeding, or anti-coagulation therapy (including anti platelet agents i.e. aspirin, clopidogrel, ticlopidine, dipyridamole, other agents inducing long-acting platelet dysfunction). Patients with history of deep venous thrombosis are allowed if treated, completely resolved, and no treatment for >4months.
  • Calcium >11.0mg/dL (2.75mmol/L) unresponsive or uncontrolled in response to standard therapy (e.g. bisphosphonates).
  • Patients who, in the opinion of the Investigator, have significant medical or psychosocial problems, including, but not limited to:

    • Other serious non-malignancy-associated conditions that may be expected to limit life expectancy or significantly increase the risk of SAEs;
    • Conditions, psychiatric, substance abuse, or other, that, in the opinion of the Investigator, would preclude informed consent, consistent follow-up, or compliance with any aspect of the study;
  • Pregnant or nursing women.
