Brief Summary

To evaluate the progression-free survival (PFS1), objective response rate (ORR), disease control rate (DCR), progression-free survival from first-line treatment initiation (PFS2), overall survival (OS), and safety of irinotecan liposome combined with bevacizumab in patients with advanced metastatic colorectal cancer.

Conditions

Metastatic Colorectal Cancer

Outcome Measures

Primary Outcomes (1)

• Progression free survival -1

  The time from initiation of maintenance therapy to first recording of PD or death, whichever occurs first. To investigate antitumor efficacy of study.

  From initial medication to the date of first documented progression or end of medication, whichever came first . Assessed up to 18 months.

Secondary Outcomes (5)

• Progression free survival -2

  The time from the start of first-line treatment to the maintenance of PD treatment or death, whichever occurs first. Assessed up to 24 months.

• Objective response rate

  From initial medication to the date of first documented progression or end of medication, whichever came first. Assessed up to 18 months

• Disease control rate

  From initial medication to the date of first documented progression or end of medication , assessed up to 18 months.

• Overall survival

  From initial medication to the date of death from any cause, Assessed up to 30 months.

• Incidence of adverse events and severity of adverse events as assessed by CTCAE 5.0

  Assessed up to 6 months.
