Biological: GSK Biologicals' 719125
Patients receive six vaccinations at two-week intervals

Detailed Description:

This Phase I/II study will be conducted according to a multicenter, open-label design. At least 20 patients will receive the vaccine as first-line and at least 20 as second-line treatment. The treatment will comprise a maximum of 18 injections of dHER2 vaccine. Follow-up phase: This will commence with the end-of-treatment examination, followed by examinations three months, six months and twelve months after the last study vaccination. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

  • At least 18 years of age.
  • Written informed consent to participate in the study.

Receipt of such instructions from the sponsor constitutes an exclusion criterion for all further patients with lung metastases.For patients being considered for second-line study treatment, the presence of lung metastases that cause any functional impairment following will result in exclusion of the patient.

  • The patient has any acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
  • The patient presents with autoimmune disease.
  • The patient requires chronic administration of immunosuppressive drugs including corticosteroids.
  • Medical history includes splenectomy or irradiation to the spleen.
  • Known family history of congenital or hereditary immunodeficiency.
  • Received major organ graft (including bone-marrow transplantation).
  • Any uncontrolled bleeding disorder or coagulation disorder or thrombocytopenia or prothrombotic disorder.
  • History of anaphylaxis or severe allergic reaction to vaccines or unknown allergens.
  • HIV positive.
