研究概览
简要总结
This cancer vaccine research study involves the injection of the NY-ESO-1b peptide along with 2 other agents to help stimulate the immune system. Peptides are small fragments of protein. NY- ESO-1 peptides are normally found in the testis and the placenta. They have also been found on various types of cancer cells. The purpose is to stimulate the immune system to react against the peptides that are found on cancer cells.
详细描述
This is a pilot study of patients of HLA-A2 phenotype whose tumor expresses the NY-ESO-1 or LAGE-1 antigen. Patients will receive NY-ESO-1b peptide mixed with 0.5 milliliter (mL) of Montanide® ISA-51 and 1 mg of CpG 7909 given every three weeks for four doses by subcutaneous injection. There will be a three-week follow-up period after the fourth injection making the cycle 13 weeks long. In the absence of toxicity and progressive disease, a second cycle will be offered to patients who have received four vaccinations.
The primary objective is to evaluate the immune response (antibodies, CD8+ T-cells, and DTH) and safety to vaccination with NY-ESO-1b peptide mixed with CpG 7909 and Montanide® in patients with cancer expressing NY-ESO-1 or LAGE-1. The secondary objective is to document tumor responses in patients with evaluable or measurable disease.

结局指标
主要结局
Number of Patients With NY-ESO-1 Specific Cellular Immunity as Measured by an Increase in NY-ESO-1b Specific CD8+ T-cells Following Treatment.
时间窗: up to 27 weeks
Blood samples were obtained at baseline, prior to the second, third and fourth injection and 2 weeks after the fourth injection in both cycles 1 and 2 for the assessment of NY-ESO-1b specific CD8+ T-cells by ELISPOT assays.
Number of Patients With Delayed-Type Hypersensitivity (DTH) Skin Reactions to NY-ESO-1b Peptide
时间窗: up to 25 weeks
10 mcg NY-ESO-1b peptide was injected intradermally at a separate site from the vaccination at baseline and after the second and fourth injection of each cycle. Assessment of DTH reactions as evidenced by redness and induration was performed 48 h after injection. The number of patients with DTH positive skin reactions was reported at each timepoint.
Number of Patients With NY-ESO-1 Specific Humoral Immunity as Determined by an Increase in Antibody Titer From Baseline.
时间窗: up to 27 weeks
Blood samples were obtained at baseline (prior to the first dose), prior to the second, third and fourth injection and 2 weeks after the fourth injection in both cycles 1 and 2 for the assessment of NY-ESO-1 specific antibodies by an enzyme-linked immunosorbent assay (ELISA). A positive response was a readable optical density at 280 nm.
Safety as Measured by the Number of Patients With Dose Limiting Toxicities (DLT)
时间窗: up to 28 weeks
DLT was defined as the following toxicities definitely, probably, or possibly related to the administration of NY-ESO-1b peptide, 100 μg mixed with 1 mg CpG 7909 and 0.5mL of Montanide® ISA-51: * ≥ Grade 2 autoimmune phenomena * Asymptomatic bronchospasm or generalized urticaria * ≥ Grade 3 hematological and non hematological toxicities.
次要结局
- Number of Patients With Tumor Responses as Measured by the Response Evaluation Criteria in Solid Tumors (RECIST)(up to 28 weeks)
