Ludwig Institute for Cancer Research
  Purpose
Mixed cancer vaccines, CHP-HER2 protein and CHP-NY-ESO-1 protein, are to be studied to evaluate the safety and immune responses in patients who are positive either or both antigens. Nine patients will be enrolled, who are refractory to standard therapies for cancer or at high risk to relapse. CHP-HER2 and CHP-NY-ESO-1 are subcutaneously given on bimonthly basis, together with OK-432(Picibanil) as an immunoadjuvant. Six doses will be given. Toxicity profiles will be monitored, and antigen specific humoral anad T cell responses will be described.

    2. have metastatic disease, and treatment has failed, or in the situation where effective therapy is not available, or has been refused.
  4. Complete recovery from surgery (at least 4 weeks).
  5. Laboratory values within the following limits:

    Hemoglobin 9.0 g/dL or more, or 10.0 g/dL or more if <50 kg Neutrophil count >1.5 x 109/L Lymphocyte count >0.5 x 109/L Platelet count >100 x 109/L Serum creatinine ≤ 1.8 mg/dL Serum bilirubin ≤ 2 mg/dL
