简要总结
This was a Phase 1, open-label, fixed-dose study of immunization with the NY-ESO-1 protein combined with CpG 7909 as an adjuvant in patients with histopathologically confirmed, high-risk Stage D1 or advanced prostate cancer. The primary study objective was to assess the safety of NY-ESO-1 protein/CpG 7909 immunization, and the secondary objective was to evaluate the immunity induced by immunization.
详细描述
Eligible patients received vaccinations consisting of the NY-ESO-1 protein (100 µg) combined with CpG 7909 (2.5 mg) administered intradermally every 3 weeks for 4 doses. Patients who demonstrated stable disease, minor response, partial response, or complete response at Week 13 may have continued to receive vaccinations until disease progression. In patients with mixed response, single progressive lesions may have been resected and vaccination may have been continued.
Safety was monitored continuously. Blood samples were obtained for clinical hematology, biochemistry and immune response assessments, including antinuclear antibody (ANA) and anti-dsDNA, NY-ESO-1 and/or LAGE-1 specific antibodies, and NY-ESO-1 specific cluster of differentiation (CD)4+ and CD8+ T cells.
A tumor sample, resected prior to immunization, was tested to determine NY-ESO-1 and/or LAGE-1 expression. Delayed-type hypersensitivity (DTH) testing was performed at baseline and on study.
Disease status was assessed at baseline and on study in patients with measurable disease.

结局指标
主要结局
Number of Patients With Treatment-emergent Adverse Events (TEAEs)
时间窗: Up to 56 weeks
Toxicity was graded in accordance with the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 3.0, as follows: Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (life-threatening), and Grade 5 (fatal). Adverse events (AEs) were reported based on clinical laboratory tests, vital sign and weight measurements, physical examinations, performance status evaluations, and any other medically indicated assessments, including patient interviews, from the first dose of study treatment through the final follow-up visit. AEs were considered to be treatment emergent (TEAE) if they occurred or worsened in severity after the first dose of study treatment.
次要结局
- Number of Patients With Cellular Antibody Response to NY-ESO-1(Up to 28 weeks)
- Number of Patients With Humoral Antibody Response to NY-ESO-1(Up to 28 weeks)
- Number of Patients With Best Tumor Response as Measured by the Response Evaluation Criteria in Solid Tumors (RECIST)(Up to 32 weeks)
