Brief summary: The incidence of melanoma is increasing with an estimated incidence of 59,940 cases and an annual death rate of 8110 in 2007. Although patients diagnosed with early stage disease have an excellent clinical outcome, patients diagnosed with advanced or recurrent disease, continue to have a high mortality rate, even with initial optimal surgical resection. Effective adjuvant strategies are needed to increase the time to progression and to decrease the recurrence rate. Immunotherapy has long been recognized as a potential therapy for melanoma; the goal of adjuvant vaccine therapy is to train the endogenous immune system to recognize and target minimal residual disease.

Detailed description: This is a Phase I open label dose escalation study of the TLR3 agonist Poly-ICLC as an adjuvant for NY-ESO-1 protein vaccination in patients with high risk melanoma in clinical complete remission (cCr), followed by a randomized Phase II component in which patients will be randomized to subcutaneous vaccination of NY-ESO-1 protein with Poly-ICLC alone dose TBD (Arm A) or with NY-ESO-1 protein, Poly-ICLC dose TBD and Montanide® ISA-51 VG (Montanide) (Arm B).

Patients with histological confirmed malignant melanoma, AJCC Stages: IIB, IIC, III or IV, who are in complete clinical remission (cCr) but at high risk of disease recurrence, will be eligible for enrollment, regardless of whether antigen expression in the autologous tumor can be demonstrated by either PCR or immunohistochemistry.

Primary Objectives:

* Phase I: To define the safety of subcutaneous vaccination with NY-ESO-1 protein, Montanide and escalating doses of Poly-ICLC.
* Phase II: To evaluate the induction of humoral and T cell (CD4+ and CD8+) immunity to subcutaneous vaccination with NY-ESO-1 protein in combination with Poly-ICLC when given with or without Montanide.

Exploratory analyses:

* Evaluation of primary tumor expression of NY-ESO-1 by IHC or RT-PCR.
* Histologic quantitation of original tumor TILs (tumor infiltrating lymphocytes), CD3+ cells, evaluation of mitotic index and correlation of this data with immunologic response.
* Correlation of NY-ESO-1 specific T cell responses with HLA type
* Investigation of polymorphisms for TLR3 through germline SNP analysis.
* Clinical Outcome (Time to Progression) reported descriptively.
* Skin section analysis of protein/adjuvant treated sites for immune cell infiltration and gene expression analysis

Eligibility criteria: Inclusion Criteria

   5. Serum creatinine \< 2.0 mg/dL
   6. Serum bilirubin \< 2 x upper limit of institutional normal
   7. AST/ALT \< 2 x upper limit of institutional normal
4. Patients must have an ECOG performance status of \<2 (ECOG criteria published in \[67\].
5. Life expectancy \> 6 months.
6. Age \> 18 years.
7. Able and willing to give written informed consent for participation in the trial (see Section 12.2).

Exclusion Criteria

6. Prior chemotherapy or vaccine therapy.
7. Radiation therapy, biological therapy or surgery within 4 weeks prior to first dose of study agent.
8. Concomitant treatment with systemic corticosteroids greater than physiologic doses. Topical (but not at the proposed vaccination sites) or inhalational steroids are permitted.
9. Participation in any other clinical trial involving another investigational agent within 4 weeks prior to first dose of study agent.
10. Pregnancy or lactation.
11. Women of childbearing potential not using a medically acceptable means of contraception.
12. Psychiatric or addictive disorders that may compromise the ability to give informed consent.
13. Lack of availability of the patient for immunological and clinical follow-up assessment.
