AK112+AK117+XELOX AK112 20 mg/kg iv day 1, AK117 20 mg/kg iv day 1 and day 8 and day15, XELOX(Oxaliplatin 130 mg/sqm iv day 1, Capecitabine via oral, the total daily dose was 2000mg/sqm, day1-14)(to be repeated every 3 weeks for a maximum of 6 cycles) If no progression occurs during AK112 plus AK117 plus XELOX, patients will receive maintenance capecitabine plus AK112 plus AK117(day 1and day 8 and day15) at the same dose used at the last cycle of the induction treatment. Capecitabine plus AK112 plus AK117 will be repeated every 3 weeks until disease progression, unacceptable toxicity or patient's refusal.
AK112+AK117+FOLFOXIRI AK112 20 mg/kg iv day 1, AK117 20 mg/kg iv day 1and day 8, FOLFOXIRI(Irinotecan 150-165 mg/sqm iv day 1, Oxaliplatin 85 mg/sqm iv day 1, Leucovorin(LV) 400 mg/sqm iv day 1, 5-fluorouracil(5-FU) 2400-2800 mg/sqm 48 h-continuous infusion, starting on day 1) (to be repeated every 2 weeks for a maximum of 8 cycles) If no progression occurs during AK112 plus AK117 plus FOLFOXIRI, patients will receive maintenance 5-FU/LV plus AK112 plus AK117(day 1and day 8) at the same dose used at the last cycle of the induction treatment. 5-FU/LV plus AK112 plus AK117 will be repeated biweekly until disease progression, unacceptable toxicity or patient's refusal.
AK112+Chemotherapy(Decided by Chemotherapy Regimen Selection Stage) AK112 20 mg/kg iv day 1, XELOX or FOLFOXIRI(the same dosage, frequency and duration with Chemotherapy Regimen Selection Stage)
AK112+AK117+Chemotherapy(Decided by Chemotherapy Regimen Selection Stage) AK112 20 mg/kg iv day 1, AK117 20 mg/kg iv day 1(qw), XELOX or FOLFOXIRI(the same dosage, frequency and duration with Chemotherapy Regimen Selection Stage)
Bevacizumab+Chemotherapy(Decided by Chemotherapy Regimen Selection Stage) Bevacizumab 5 mg/kg iv day 1(q2w) or 7.5 mg/kg iv day 1(q3w), XELOX or FOLFOXIRI(the same dosage, frequency and duration with Chemotherapy Regimen Selection Stage)
Subjects receive AK112 until disease progression or unacceptable toxicity AK112 20 mg/kg iv day 1(to be repeated every 3 weeks until disease progression, unacceptable toxicity or patient's refusal)
Subjects receive AK117 and AK112 until disease progression or unacceptable toxicity AK112 20 mg/kg iv day 1, AK117 20 mg/kg iv day 1(qw)(to be repeated every 3 weeks until disease progression, unacceptable toxicity or patient's refusal)
