Brief Summary

Subjects will receive immunizations every other week for 8 immunizations prior to clinical and immunological evaluations. Patients will then receive immunizations every month up to one year. Cyclophosphamide will be administered intravenously 3 days prior to the first immunization, 3rd, 5th, 7th, 9th, and subsequent monthly immunizations. Women and men \>= 18 years of age with refractory metastatic malignancies that express NY-ESO-1 by RT-PCR or immunohistochemistry. Alternatively, patients may be elected on the basis of serum anti-NY-ESO-!-antibodies as detected by ELISA. Primary Objective: To evaluate the toxicity profile of the regimens described in Section 1.6. Secondary Objective: To detect and quantitate immune responses induced by the proposed peptide vaccine or protein vaccine in association with CpG 7909 and cyclophosphamide. This endpoint will be assessed by an IFN-y ELISPOT assay of NY-ESO-1-specific tumor-reactive CD8 + T cells. We also will look for NY-ESO-1 tetramer CD8+ T cells, Delayed-type Hypersensitivity (DTH), and NY-ESO-1-specific CD4+ T cell responses with ELISPOT assays and cytokine-release-assays. Tertiary Objectives: To evaluate tumor response in terms of clinical tumor regression and progression-free interval. To evaluate the survival of patients treated with the regimens described in Section 1.6. The first 3 patients will be assigned treatment A. All three patients will be treated and observed for one month. If no DLTs are observed in the first 3 patients, accrual to arm A will be put on hold and accrual will continue with Arm B. However, if 1 DLT is observed in Arm A, up to 3 additional patients will be treated on Arm A, until either 2 DLTs have been observed, or 6 patients have been treated with just 1 DLT among them. If 2 DLTs are observed in Arm A, the study will terminate and all treatments will be deemed intolerable. The same principles apply to the cohorts treated on B-E: if the number of DLTs (after one month of treatment) is zero, accrual proceeds to the next treatment group; if it is 1, accrual continues with the same treatment for up to 3 additional patients; if it is 2, no patients will be treated on the remaining treatment arms.

Study Arms (6)

A

EXPERIMENTAL

PF-3512676, and three MHC class I Montanide ISA 720 VG and the peptides NY-ESO-1 157-165V, NY-ESO-1 53-62 and NY-ESO-1 94-102 will be administered in three separate subcutaneous (under the skin) injections.

Biological: Vaccine only

B

EXPERIMENTAL

This vaccine injection contains all the same components of Arm A and will also be administered in 3 separate subcutaneous injections. However, 3 days prior to your 1st, 3rd, 5th, 7th, 9th and subsequent monthly vaccinations, you will have low-dose cyclophosphamide administered intravenously (through a vein in your arm). Cyclophosphamide is an agent that is thought to increase the anti-tumor response of vaccines.

Biological: Vaccine only

D

EXPERIMENTAL

This vaccine injection contains all the same components of Arm C and will also be administered in 3 separate subcutaneous injections. However, 3 days prior to your 1st, 3rd, 5th, 7th, 9th and subsequent monthly vaccinations, you will have low-dose cyclophosphamide administered intravenously (through a vein in your arm).

Biological: Vaccine + cyclophosphamide

E

EXPERIMENTAL

PF-3512676, Montanide ISA 720 VG and the NY-ESO-1 protein will be administered in three separate subcutaneous injections.

Biological: Vaccine only

F

EXPERIMENTAL

This vaccine injection contains all the same components of Arm E and will also be administered in 3 separate subcutaneous injections. However, 3 days prior to your 1st, 3rd, 5th, 7th, 9th and subsequent monthly vaccinations, you will have low-dose cyclophosphamide administered intravenously (through a vein in your arm).

Interventions

Vaccine only BIOLOGICAL

PF-3512676, Montanide ISA 720 VG and MHC class I peptides from NY-ESO-1 (NY-ESO-1 157-165V, NY-ESO-1 53-62 (MPS-190) and NY-ESO-1 94-102) in three subcutaneous injections (i.e., 1mg of PF-3512676 at 15mg/ml and 50 μg of each peptide (2mg/ml) for each of the three injections + Montanide ISA 720 VG + saline). The final volume of immunization will be 4.5 ml administered as 3 separate 1.5 ml subcutaneous injections. The remaining 1.5 ml will be used for sterility testing. Each injection will be done in the vicinity of the nodal drainage of one extremity.

A

Vaccine + cyclophosphamide BIOLOGICAL

PF-3512676, Montanide ISA 720 VG and three MHC class I-restricted epitopes from NY-ESO-1 (NY-ESO-1 157-165V, NY-ESO-1 53-62 (MPS-190) and NY-ESO-1 94-102) and cyclophosphamide. The vaccine preparation is identical to arm A. Each injection will be done in the vicinity of the nodal drainage of one extremity. Each will consist of 1.5 ml of product. Low-dose cyclophosphamide (300mg/m2) will be given IV, monthly, 3 days prior to the first, 3rd, 5th, 7th, 9th, and subsequent monthly immunizations.
