Solid Tumors

Brief summary

In this study, the investigators examine using a combination of two types of HLA-A\*2402 (or HLA-A\*0201)-restricted epitope peptides, which were derived from VEGF-R1 and VEGF-R2 the safety, immunogenicity, and antitumor effect of vaccine treatment for advanced solid tumor patients who are refractory to standard therapy.

Detailed description

The purpose of this study is to evaluate the safety, tolerability, immune response and clinical efficacies of HLA-A\*2402 or HLA-A\*0201 restricted epitope peptides (VEGF-R1 and VEGF-R2) emulsified with Montanide ISA 51 for advanced solid tumors. In this phase I/II trial, the investigators examine using a combination of the two peptides the safety, immunogenicity, and antitumor effect of vaccine treatment for HLA-A\*2402 or HLA-A\*0201-positive advanced solid tumor patients who are refractory to standard therapy.

Interventions

BIOLOGICALHLA-A*2402 or A*0201 restricted peptides

Open Label, Non-Randomized, Safety/Efficacy study: 1. HLA-A\*2402-positive patients will be vaccinated subcutaneously once a week with HLA-A\*2402 restricted peptides for VEGF-R1 and VEGF-R2 with adjuvant. 2. HLA-A\*0201-positive patients will be vaccinated subcutaneously once a week with HLA-A\*0201 restricted peptides for VEGF-R1 and VEGF-R2 with adjuvant.
