Interventions/Control_1	OBP-301: Intratumoral injection directly into the target region of a tumor at Day 1, Day 15, and Day 29 Dose of OBP-301 in Phase 1a: 1x10^10 (Cohort 1), 1x10^11 (Cohort 2), 1x10^12VP (Cohort 3)(VP:virus particle) Additional administration of OBP-301 After the recommended dose of OBP-301 has been established, additional administration of OBP-301 is allowed. After completion of administration of OBP-301 on Day 1 - Day 29(+/- 4 days), if the target region has not disappeared, additional administration of OBP-301 is allowed after Day 43 or later. The patients in Phase 1a, Pembrolizumab administration has continued, are included. The recommended dose determined in the Phase 1a part will be administered 3 times biweekly (+/- 4 days); max 4 cycles. Pembrolizumab: Administration at a dose of 200 mg/body on Day 8.
