The purpose of this study is to assess the safety of repeated doses of cholesterol-bearing hydrophobized pullulan (CHP) and NY-ESO-1 protein (CHP-NY-ESO-1) and describe the NY-ESO-1 specific-humoral and cellular immune response to immunization with CHP-NY-ESO-1 in patients with cancer expressing NY-ESO-1.

Condition Intervention Phase
Neoplasms Biological: protein vaccination Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Immunization of Patients With Tumors Expressing NY-ESO-1 or LAGE Antigen With Complex of NY-ESO-1 Protein and Cholesterol-bearing Hydrophobized Pullulan (CHP)

Further study details as provided by Ludwig Institute for Cancer Research:

Primary Outcome Measures:
  • NY-ESO-1-specific immune responses

Secondary Outcome Measures:
  • tumor responses

Estimated Enrollment: 9
Study Start Date: June 2004
Study Completion Date: December 2006
Detailed Description:

NY-ESO-1 was isolated by serological analysis of recombinant cDNA expression libraries (SEREX), using tumor mRNA and autologous serum from an esophageal cancer patient. Reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that NY-ESO-1 displayed the typical expression pattern of CT antigens. NY-ESO-1 mRNA was expressed only in testis of normal tissues tested and in various types of cancer, including lung cancer, breast cancer, malignant melanoma and bladder cancer. LAGE-1 was identified by the representational difference analysis and revealed to display 84% amino acid homology with NY-ESO-1. In most cases, expression of LAGE-1 parallels the expression of NY-ESO-1. Since testis is an immune privileged organ where HLA molecules are not expressed, these antigens can be considered tumor-specific.

Because of frequent NY-ESO-1 mRNA expression and high immunogenicity in advanced cancer, NY-ESO-1 is an attractive target molecule for a cancer vaccine. Current therapies against advanced cancer have limited effectiveness. The idea of vaccination with NY-ESO-1 protein in cancer patients with tumors expressing NY-ESO-1 mRNA is based on two findings: 1) the number of CD8+ T cell epitopes identified in NY-ESO-1 molecule are limited to those binding to HLA-A0201, A31, Cw3 and Cw6. These HLA subtypes are carried by a minor Japanese population; 2) CD8+ T cell responses specific to NY-ESO-1 are polyclonal. Protein vaccination may induce immune response more effectively against tumors expressing NY-ESO-1 than peptide immunization.
