Brief Summary

To explore the safety and efficacy of Surufatinib and Sintilimab in Combination With Capecitabine in Patients With Previously Treated Metastatic Adenocarcinoma of Small Intestine or Appendix Carcinoma : a Single-arm, a Single-center , Phase 2 Trial. Meanwhile, Exploring the maximum tolerant dose or recommended II research dose of Surufatinib combined with a fixed dose of Sintilimab and Capecitabine using 3 + 3 dose climbing experiment.

Conditions

Adenocarcinoma of Small Intestine; Appendix Carcinoma; Metastatic

Outcome Measures

Primary Outcomes (1)

• Progression-free survival (PFS)

  The PFS is defined as the time from the start of treatment to the date of first documented PD or death as a result of any cause, whichever occurred first. When a patient was alive and without progression, PFS was censored at the date of the last disease assessment.

  2 year

Secondary Outcomes (4)

• Objective response rate (ORR)

  2 year

• Overall Survival (OS)

  2 year

• Disease Control Rate (DCR)

  2 year

• Safety variables (Incidence of Adverse Events [Safety and Tolerability])

  2 year

Study Arms (1)

Surufatinib and Sintilimab in Combination With Capecitabine

EXPERIMENTAL

Patients were given solventinib (a "3+3" design was adopted in the dose exploration phase, with two dose levels of 200mg and 250mg for dose exploration; after the recommended dose was determined in the dose exploration phase, the dose amplification phase was entered), once a day (QD) for continuous administration * sindilizumab, 200mg, iv every 3 weeks (Q3W) * Capecitabine, 1000mg/m2, twice a day (BID, once in the morning and once in the evening), orally after meals, stopped for 1 week after 2 weeks of treatment; The three-drug combination therapy was continued every 3 weeks in a cycle until patients developed disease progression or met other criteria for termination of study treatment specified in the protocol.
