Arm | Intervention/treatment |
---|---|
Experimental: ONO-4538 + SOX Therapy Cohort (Part 1)
ONO-4538 360 mg solution intravenously for 30 min in every 3 weeks. Oxaliplatin 130 mg/m2 (BSA) solution intravenously for 2 hours once-daily, followed by 20 days off. Tegafur-gimeracil-oteracil potassium combination drug 40 - 60 mg bid orally in 14 days, followed by 7 days off Each drug will be continued until documented disease progression, discontinuation due to toxicity, withdrawal of consent or the study ends. |
Drug: ONO-4538 Drug: Oxaliplatin Drug: Tegafur- Gimeracil-Oteracil potassium |
Experimental: ONO-4538 + CapeOX Therapy Cohort (Part 1)
ONO-4538 360 mg solution intravenously for 30 min in every 3 weeks. Oxaliplatin 130 mg/m2 (body surface area) solution intravenously for 2 hours once-daily, followed by 20 days off. Capecitabine 1200 - 2100 mg bid orally in 14 days, followed by 7 days off. Each drug will be continued until documented disease progression, discontinuation due to toxicity, withdrawal of consent or the study ends. |
Drug: ONO-4538 Drug: Oxaliplatin Drug: Capecitabine |
Experimental: ONO-4538 + chemotherapy group (Part 2)
With regard to the ONO-4538 + chemotherapy group, either SOX therapy or CapeOX therapy will be selected as the chemotherapy by the investigator or the subinvestigator, taking into account the condition of each subject. ONO-4538 360 mg solution intravenously for 30 min in every 3 weeks. Oxaliplatin 130 mg/m2 (body surface area) solution intravenously for 2 hours once-daily, followed by 20 days off. Tegafur-gimeracil-oteracil potassium combination drug 40 - 60 mg bid or Capecitabine 1000 mg/ m2 (body surface area) bid orally in 14 days, followed by 7 days off. Each drug will be continued until documented disease progression, discontinuation due to toxicity, withdrawal of consent or the study ends. |
Drug: ONO-4538 Drug: Oxaliplatin Drug: Tegafur- Gimeracil-Oteracil potassium Drug: Capecitabine |
Placebo Comparator: Placebo + Chemotherapy group (Part 2)
With regard to the placebo + chemotherapy group, either SOX therapy or CapeOX therapy will be selected as the chemotherapy by the investigator or the subinvestigator, taking into account the condition of each subject. Placebo solution intravenously for 30 min in every 3 weeks. Oxaliplatin 130 mg/m2 (body surface area) solution intravenously for 2 hours once-daily, followed by 20 days off.
