Experimental: S-588210 (S-488210 + S-488211)
Participants will receive subcutaneous injections once a week for 4 weeks and then a biweekly extension treatment for 8 weeks. Each treatment will consist of 1 subcutaneous injection of 1 mL of S- 488210 and 1 subcutaneous injection of 1 mL of S-488211 containing 1 mg each of the 5 peptides.
S-488210 is a freeze-dried injectable formulation containing the following three peptides, S-488201 (a URLC10-derived peptide), S-488202 (a CDCA1-derived peptide) and S-488203 (a KOC1-derived peptide).
Other Name: S-588210
S-488211 is a freeze-dried injectable formulation containing the following two peptides, S-488204 (a DEPDC1-derived peptide) and S-488205 (an MPHOSPH1-derived peptide).
Other Name: S-588210
- Number of Participants with Adverse Events [ Time Frame: Up to 16 weeks ]Adverse events will be classified by system organ class and preferred term using Medical Dictionary for Regulatory Activities (MedDRA).
- Cytotoxic T Lymphocyte (CTL) Induction Rate [ Time Frame: Baseline and Weeks 8 and 12 ]CTL induction is defined as the increase in CTL activity at any point after baseline. Accordingly, the CTL induction rate is calculated as the percentage of participants who show CTL induction to at least any of the 5 antigens.
