Safety and Efficacy Study of the Trifunctional Antibody Ertumaxomab to Treat Patients With Advanced or Metastatic Breast Cancer (IV REXBC 02)

April 30, 2015 updated by: Neovii Biotech

Phase II Study of the Trifunctional Anti-HER-2/Neu x Anti-CD3 Antibody Ertumaxomab for Hormone Therapy Refractory Patients With Her-2/Neu 1+ or 2+ Expressing Advanced or Metastatic Breast Cancer

The purpose of this study is to determine the safety and efficacy of the investigational trifunctional anti-Her-2/neu x anti-CD3 antibody ertumaxomab as treatment for hormone therapy refractory Her-2/neu 1+ or 2+ expressing advanced or metastatic breast cancer

Detailed Description

A multi-centre, phase II study of ertumaxomab in metastatic breast cancer patients who became progressive after hormonal therapy. Each eligible patient will receive three ascending doses of ertumaxomab, administered intravenously. Ertumaxomab will be administered as a 3-hour constant rate infusion with a dosing interval of 7 days. Each patient will participate in this study for up to 7 months (includes the up to 21 days screening period, 14 days treatment period, and up to 180 days/6 months follow-up), with 3-monthly post-study follow-up until the patient becomes progressive.

  • Patients must have had disease progression after hormonal therapy including at least one aromatase inhibitor.
  • Adequate hematological, liver and kidney function:

    • Thrombocytes ³ 100000 / mm³ (= 100 x 109 /l)
    • Hemoglobin ³ 10 g/dl
    • Neutrophil count ³ 1500/mm³ (= 1.5 x 109 /l)
    • WBC ³ 3 X 109 /l
    • Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvate transaminase (SGPT) ≤ 2.5 x upper limit of normal (ULN)
    • Serum bilirubin ≤ 2 x ULN
    • Creatinine ≤ 1.5 x ULN or clearance ³ 60 ml/min
  • No life-threatening visceral disease.
  • No known brain or central nervous system metastases.
  • No symptomatic pleural effusions.
  • No symptomatic pericardial effusions.
  • No subjects whose only site of metastatic involvement is bone metastases with the exception of those with a measurable soft tissue component of the bone lesion seen with imaging that does not require palliative radiation intervention and/or the patient has a lytic bone lesion ³ 1 cm measured with radiography that can be followed for evidence of re-calcification.
  • No history of relevant cardiovascular disease:

    • LVEF within the institutional ranges of normal as measured by echocardiogram or MUGA scan
    • No prior uncontrolled or symptomatic congestive heart failure NYHA ³ 2
    • No myocardial infarction within the past two years
    • No uncontrolled or symptomatic cardiac arrhythmias
  • No severe dyspnea.
  • No pulmonary dysfunction or need for continuous supportive oxygen inhalation.
  • No other concurrent uncontrolled co-morbid illness.
  • No other concurrent malignancy, except treated basal cell or squamous cell carcinoma of the skin, or in situ carcinoma of the cervix.
  • Patients with documented autoimmune diseases (such as lupus) are excluded from participation in the study unless a waiver is granted by the responsible medical monitor.
  • Patients with a human immunodeficiency virus, hepatitis B or hepatitis C positive status are excluded from participation in the study.
  • No prior or concurrent chemotherapy regimen for advanced or metastatic disease.
  • Prior neo-adjuvant or adjuvant chemotherapy is allowed provided it was stopped at least six months before study entry.
  • No concurrent hormone therapy (hormone therapy must be stopped at the screening visit).
  • At least 4 weeks since prior radiotherapy.
  • No concurrent immune therapy.
  • No concurrent corticosteroid therapy.
  • No regularly used medication for a health condition or comorbidity that might result in undue risk to the patient.
  • No prior investigational treatment for advanced or metastatic disease.
  • Able and willing to comply fully with the protocol.
