Brief summary
This study is a randomized, controlled, open-label, phase II clinical study. This study is designed to evaluate the efficacy and safety of second-line standard treatment sequential TAS-102 and bevacizumab combined with local treatment versus continuous treatment of standard second-line therapy in advanced colorectal cancer.
Detailed description
This study is a randomized, controlled, open-label, phase II clinical study. This study is designed to evaluate the efficacy and safety of second-line standard treatment sequential TAS-102 and bevacizumab combined with local treatment versus continuous treatment of standard second-line therapy in advanced colorectal cancer. In this study, 119 metastatic colorectal cancer patients who reach CR/PR/SD after 3 months second-line treatment will be randomized to receive sequential TAS-102 +bevacizumab combined with local treatment or continuous treatment of previous second-line therapy. The primary endpoint is investigator-assessed time to treatment failure (TTF). Secondary endpoints include ORR, DCR, PFS, OS, safety and patient reported outcomes.
Interventions
patients achieve disease control after second-line induction therapy with standard therapy(FOLFOX/FOLFIRI/XELOX/ mXELIRI+bevacizumab/cetuximab), then achieve TAS-102+bevacizumab+local treatment
Standard therapy:FOLFOX/FOLFIRI/XELOX/ mXELIRI±bevacizumab/cetuximab

Acute or subacute intestinal obstruction, or chronic inflammatory bowel disease; 10. There are serious psychological or psychiatric abnormalities that affect the compliance of patients to participate in this clinical study. * Has undergone major surgical treatment (excluding diagnosis) within 4 weeks before the start of the study or is expected to undergo major surgical treatment during the study period; * Inability to swallow pills, presence of malabsorption syndrome or any condition affecting gastrointestinal absorption; * The investigator assessed that it is not appropriate to participate in the study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to treatment failure (TTF) | up to approximately 2 years. | TTF is defined as the time from the date of randomization to the date of the discontinuation of the trial protocol. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Disease control rate (DCR) | up to approximately 2 years. | DCR was defined as the percentage of patients who have achieved complete response (CR), partial response (PR) and stable disease (SD). |
| Progression-free survival (PFS) | up to approximately 2 years. | PFS is defined as the time from randomization until the date of first occurrence of investigator-assessed radiological disease progression or death due to any cause, whichever came first. |
| Overall survival(OS) | up to approximately 2 years. | OS is defined as the time from the date of randomization to the date of death due to any cause. |
| Objective response rate (ORR) | up to approximately 2 years. | ORR is defined as the percentage of subjects with complete response (CR) or partial response (PR) by investigator assessment per RECIST criteria, version 1.1. |
| European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) | up to approximately 2 years. | To compare change in Quality of Life, as defined by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30 (Version 3)) during study treatment. The EORTC QLQ-C30 (Version 3) uses for the questions 1 to 28 a 4-point scale. The scale scores from 1 to 4: 1 (Not at all), 2 (A little), 3 (Quite a bit) and 4 (Very much). Half points are not allowed. The range is 3. For the raw score, less points are considered to have a better outcome. The EORTC QLQ-C30 (Version 3) uses for the questions 29 and 30 a 7-points scale. The scale scores from 1 to 7: 1 (very poor) to 7 (excellent). Half points are not allowed. The range is 6. More points are considered to have a better outcome. |
| Progression-free survival(PFS2) | up to approximately 2 years. | PFS2 is defined as the time from receiving second-line standard therapy until the date of first occurrence of investigator-assessed radiological disease progression or death due to any cause, whichever came first. |
| Adverse Events | up to approximately 2 years. | AE assessed by NCI-CTCAE v5.0. |
