Study Arms:
- Camrelizumab combined with Apatinib and Capecitabine (Type: EXPERIMENTAL): Camrelizumab was administered 200mg iv every 3 weeks. Capecitabine was administered 1000mg/m2 orally, b.i.d. every 3 weeks (Day 1-14 of a treatment cycle) Apatinib:A safety-run-in was conducted in the first cycle to identify the recommended dose of Apatinib, the initial dose was administered 250mg orally daily every 3 weeks (Day 1-14 of a treatment cycle). The dose of Apatinib increase and reduction was 250 mg orally q.d. and 250 mg orally q.o.d. every 3 weeks respectively according to the number of doses limiting toxicity events (DLTs) in the initial group. The final dose of Apatinib for the extension stage was detemained by the result of safety-run-in stage.

Based on this trial design, predict the completion outcome and termination type (if applicable).
