The aim of study is to investigate the immunity-enhancing effects, safety , clinical efficacy of personalized peptide vaccination in combination with Dai-kenchu-to for colorectal cancer patients resistant to standard therapies.
Safety,Efficacy
Exploratory
Pragmatic
Phase II
Comparison of immune-enhancing effects (changes in anti-peptide IgG titers in plasma)between two groups.
1.Comparison of peptide-specific CTL responses in PBMCs between two groups.
2. Comparison of safety between two groups.
3. Comparison of overall survival between two groups .

arm1:
The right peptides (up to 4 peptides) for vaccination to individual patients will be selected in consideration of the pre-existing host immunity assessed by the titers of anti-peptide IgG before vaccination, and subcutaneously injected with incomplete Freund's adjuvant every week (3.0 mg/each peptide; 6 times/cycle).
Dai-kenchu-to(5 g/time, 3 times/day) will be orally administered from the date of the first vaccination to the date of the sixth vaccination.
If the patients want to continue the vaccination after completion of the first cycle of 6 vaccinations, the peptide vaccination will be allowed to continue (every 2-4 weeks).
arm2:
The right peptides (up to 4 peptides) for vaccination to individual patients will be selected in consideration of the pre-existing host immunity assessed by the titers of anti-peptide IgG before vaccination, and subcutaneously injected with incomplete Freund's adjuvant every week (3.0 mg/each peptide; 6 times/cycle).
If the patients want to continue the vaccination after completion of the first cycle of 6 vaccinations, the peptide vaccination will be allowed to continue (every 2-4 weeks).

5) (Females) Pregnant or nursing patients. Patients desiring future fertility.
(Males) Patients who do not accept contraception from the 1st vaccination until 70 days after the last vaccination.
6) Patients who are judged inappropriate for entry to this clinical trial by doctors.
