Objectives
Narrative objectives1
The aims of this trial are to evaluate safety of personalized peptide vaccine in combination with anti-IL6 receptor antibody and to examine the specific immunological responses to vaccine for determining an optimal dose of anti-IL6 receptor antibody in refractory colorectal cancer patients, who showed elevated plasma IL-6 more than 3 pg/ml.

Interventions/Control_1
Anti-IL6 receptor antibody [Actemra (tocilizumab), Chugai Pharmaceutical Co; 0.5mg/kg (n=6), 2mg/kg (n=6), or 8mg/kg (n=6)] is intravenously administrated. After three days, a maximum of 4 peptides (3 mg/each peptide), which are selected based on the results of HLA typing and peptide-specific IgG titers, are subcutaneously administrated with incomplete Freund's adjuvant (Montanide ISA51, Seppic)once a week for consecutive 6 weeks. During the treatment, safety is evaluated.The dose of anti-IL6 receptor antibody is escalated, if the safty is confirmed in 6 independent patients at the same dose.
