• Biological: Peptides
  NY-ESO-l 157-165 (165V) and gpl002 80-288 (288V) peptides each at a dose of 0.5 mg will be emulsified with Montanide ISA 51 VG and administered to all patients in the study at Weeks 1,3, 5, 7, 9, 11, 17, 21, 25 33, 41, and 53. Peptides will be administered as a total of 6 deep subcutaneous (s.c.) injections into alternating lower extremities one hour after CP 870,893 infusions.

  The dosage of poly IC:LC chosen for the current trials has been used safely in over one hundred patients with central nervous system (CNS) malignancies enrolled in nitrates and bone turnover (NABT) trials. The injection of 1000 mcg will be made deeply subcutaneously into the same limb as the peptides/Montanide ISA 51 VG, at least 5 cm. proximal to the peptides vaccination site. Poly IC:LC will be administered to all patients in the study at Weeks 1, 3, 5, 7, 9, 11, 17, 21, 25 33, 41, and 53 one hour after CP 870,893 infusion.

• Life expectancy ? 6 months
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
• Patients with resected brain metastases that are off steroids, have no evidence of disease by brain magnetic resonance imaging (MRI) scanning, or computer tomography (CT) of the brain if an MRI cannot be performed, are eligible.
• Screening laboratory values must meet the following criteria: white blood cell (WBC): ?2500 cells/mm³; absolute neutrophil count (ANC): ?1500 cells/mm³, Platelets: ?100,000/mm³; Hematocrit: ?30%; Hemoglobin: ?10 g/dL; Creatinine: ?2.0 mg/dL; aspartate aminotransferase (AST): ?3 x ULN; Bilirubin: ?1.0 x upper limit of normal (ULN) (except patients with Gilbert's Syndrome who must have a total bilirubin less than 3.0 mg/dL); human immunodeficiency virus (HIV): negative; HBsAg: negative; hepatitis C virus (HCV) antibody [anti-HCV Ab]: nonreactive. If reactive, patient must have a negative HCV RNA qualitative PCR.

Exclusion Criteria:

• Any prior malignancy except for the following: adequately treated basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix, or any other cancer from which the patient has been disease-free for at least 5 years.
• History of any autoimmune disease, specifically including the following diseases: inflammatory bowel disease or any other autoimmune bowel diseases; systemic lupus erythematosis; rheumatoid arthritis; or any autoimmune ocular diseases. Patients with an autoimmune disease history affecting the pancreas, pituitary, liver, gastrointestinal (GI) tract or adrenals, and prior history of Guillan-Barre and other neurologic conditions felt to be autoimmune in nature are also excluded.
• Active infection, requiring therapy, chronic active hepatitis B virus (HBV) or HCV, or confirmed reactivity with HIV tests.
• Pregnancy or nursing: due to the possibility that CP 870,893 could have a detrimental effect on the developing immune system of the fetus or infant, exposure in utero or via breast milk will not be allowed.
• Systemic hypersensitivity to Montanide ISA 51 (IFA), Montanide ISA 51 VG or any vaccine component

• Prior treatment with CP 870,893 or any anti-CD40 antibody
• Evidence or history of significant cardiac, pulmonary, hepatic, renal, psychiatric or gastrointestinal disease that would make the administration of CP 870,893 unsafe
• Concurrent treatment with chemotherapy or other immunotherapy regimens (must be completed at least 4 weeks before Screening; 6 weeks for nitrosoureas); prior treatment with chemotherapy, radiotherapy or other than anti CD40 antibodies will not be an exclusion.
