Clinical Trial Summary

This study is a randomized, controlled, open-label, multicentre clinical study. This study is designed to evaluate the efficacy and safety of TAS-102 combined with bevacizumab as second-line maintenance therapy versus standard chemotherapy combined with bevacizumab as second-line continuous therapy in advanced colorectal cancer after second-line induction therapy.

Description:

This study is a randomized, controlled, open-label, multicentre clinical study. This study is designed to evaluate the efficacy and safety of TAS-102 combined with bevacizumab as second-line maintenance therapy versus standard chemotherapy combined with bevacizumab as second-line continuous therapy in advanced colorectal cancer after second-line induction therapy.

The primary endpoint is investigator-assessed time to treatment failure (TTF). Secondary endpoints include ORR, DCR, DoR, PFS, OS, safety and patient reported outcomes.

This study plans to enroll 224 patients with advanced colorectal cancer who have previously achieved disease control after second-line induction therapy with standard chemotherapy (FOLFOX, FOLFIRI, or CAPEOX) combined with bevacizumab.

The subjects will be randomly assigned in a 1:1 ratio to the TAS-102 combined with bevacizumab second-line maintenance treatment group (experimental group) and the standard chemotherapy combined with bevacizumab second-line continuous treatment group (control group).

Male subjects also have to agree not to donate sperm during the same period.

Exclusion Criteria:

4. Have bleeding tendency and high risk of bleeding;

5. Known inherited or acquired bleeding (e.g., coagulopathy) or thrombophilia, as in patients with hemophilia; Current or recent (within 10 days before initiation of study treatment) use of a full-dose oral or injectable anticoagulant or thrombolytic agent for therapeutic purposes (prophylactic use of low-dose aspirin and low-molecular-weight heparin is allowed);

6. Thrombotic or embolic events, such as cerebrovascular accident (including transient ischemic attack, cerebral hemorrhage, cerebral infarction), pulmonary embolism, etc., occurred within 6 months before the initiation of study treatment;

7. Severe, unhealed or dehiscence wounds and active ulcers or untreated fractures;

8. 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;

9. Inability to swallow tablets, malabsorption syndrome or any condition affecting gastrointestinal absorption;

11. Active hepatitis (hepatitis B reference: HBsAg positive and HBV DNA=2000 IU/ml; Hepatitis C reference: HCV antibody positive and HCV virus copy number > upper limit of normal);

12. Known brain and/or leptomeningeal metastases. All subjects should receive brain CT/MRI to exclude brain metastases;

13. Active infection or fever of unknown origin > 38.5 ° C within 2 weeks before the first dose (tumor-related fever, as judged by the investigator, was eligible);

14. Acute or subacute intestinal obstruction, or chronic inflammatory bowel disease;

15. Have poorly controlled cardiac clinical symptoms or disease;

16. Patients with other malignant tumors within 5 years before enrollment, except basal cell carcinoma of the skin or carcinoma in situ of the cervix;

17. Pregnant or lactating women;

18. Patients with genotype MSI-H;

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to treatment failure (TTF)	TTF is defined as the time from the date of randomization to the date of the discontinuation of the trial protocol.	up to approximately 2 years.
Secondary	Objective response rate (ORR)	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.	up to approximately 2 years.
Secondary	Disease control rate (DCR)	DCR was defined as the percentage of patients who have achieved complete response (CR), partial response (PR) and stable disease (SD).	up to approximately 2 years.
Secondary	Duration of Response (DoR)	Response will be determined by investigator using RECIST 1.1.	up to approximately 2 years.
Secondary	Progression-free survival (PFS)	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.	up to approximately 2 years.
Secondary	Overall survival(OS)	OS is defined as the time from the date of randomization to the date of death due to any cause.	up to approximately 2 years.

Secondary	European Quality of Life Five Dimensions Five Level Scale Questionnaire (EQ-5D-5L)	EQ-5D-5L is an abbreviation for "European Quality of life - 5 Dimensions - 5 Level" and measures Quality of Life. The scale has five subcomponents with scores from 1 (best) to 5 (worst).	up to approximately 2 years.
Secondary	European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30)	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.	up to approximately 2 years.
