入选标准
- •Histologically proven diagnosis of colorectal cancer;
- •Previous adjuvant chemotherapy allowed only if with fluoropyrimidine monotherapy and more than 6 months elapsed between the end of adjuvant and first relapse;
- •Neutrophils >1.5 x 109/L, Platelets >100 x 109/L, Hb >9 g/dl;
- •Total bilirubin ≤1.5 times the upper-normal limits (UNL) of the normal values and AST (SGOT) and/or ALT (SGPT) <2.5 x UNL (or <5 x UNL in case of liver metastases) alkaline phosphatase <2.5 x UNL (or <5 x UNL in case of liver metastases);
- •Creatinine clearance ≥50 mL/min or serum creatinine ≤1.5 x UNL;
- •INR or aPTT ≤1.5 x ULN. This applies only to patients who are not receiving therapeutic anticoagulation;
- •Urine dipstick of proteinuria <2+. Patients discovered to have 2+ proteinuria on dipstick urinalysis at baseline, should undergo a 24-hour urine collection and must demonstrate ≤1 g of protein/24 h;
- •Women of childbearing potential must have a negative blood pregnancy test at the baseline visit. For this trial, women of childbearing potential are defined as all women after puberty, unless they are postmenopausal for at least 12 continuous months, are surgically sterile, or are sexually inactive. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient;
- •Male subjects with female partners of childbearing potential and female subjects of childbearing potential must, therefore, be willing to use adequate contraception as approved by the investigator (barrier contraceptive measure or oral contraception) and outlined in “Section 6.5 – Contraception”, starting with the first dose of study therapy through 6 months after the last dose of bevacizumab and fluorouracil and within 5 months after the last dose of atezolizumab. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject;
- •Females of childbearing potential must have a negative blood pregnancy test at the baseline visit. For this trial, women of childbearing potential are defined as all women after puberty, unless they are postmenopausal for at least 12 continuous months, are surgically sterile or sexually inactive;
- •Will and ability to comply with the protocol;
- •Initially unresectable metastatic colorectal cancer not previously treated with chemotherapy for metastatic disease;
- •Written informed consent to study procedures.
- •Proficient mismatch repair (pMMR) status in tumour tissue (primary or metastatic), as determined by a local laboratory assay in a CLIA- or similarly certified;
- •Immunoscore IC-high status in tumour tissue (primary or metastatic), as determined by a sponsor-defined central laboratory (HEGP, AP-HP, INSERM, France). Note: in case of metachronous disease, tumour tissue re-biopsy could be optionally performed only if it can be carried out safely with minimal risk and discomfort and patient’s disease is easily accessible. Fine-needle or cytological aspirates are not acceptable;
- •At least one measurable lesion according to RECIST criteria (version 1.1);
- •Availability of adequate tumour specimen (primary or metastatic);
- •Male or female of 18-75 years of age;
- •ECOG PS ≤ 2 if aged < 71 years, ECOG PS = 0 if aged 71-75 years;
- •Life expectancy of at least 12 weeks;

- •Other co-existing malignancies or malignancies diagnosed within the last 5 years with the exception of localized basal and squamous cell carcinoma or cervical cancer in situ;
- •Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to study treatment start, or anticipation of the need for major surgical procedure during the course of the study;
- •Core biopsy or other minor surgical procedure, excluding placement of a vascular access device, within 7 days prior to initiation of study treatment;

次要结局
- Overall Toxicity Rate is defined as the percentage of patients, relative to the total of enrolled subjects, experiencing any adverse event, according to National Cancer Institute Common Toxicity Criteria (version 5.0)3, during the induction and the maintenance phases of treatment.
- Toxicity Rate is defined as the percentage of patients, relative to the total of enrolled subjects, experiencing a specific adverse event of grade 3/4, according to National Cancer Institute Common Toxicity Criteria (version 5.0)3, during the induction and the maintenance phases of treatment.
- Objective Response Rate (ORR) is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR) or partial (PR) response, according to RECIST 1.1 criteria1, during the induction and the maintenance phases of treatment.

- Immuno-related Objective Response Rate (irORR) is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR) or partial (PR) response, according to immune-modified RECIST criteria2, during the induction and the maintenance phases of treatment. The determination of clinical response will be based on investigator reported measurements. Responses will be evaluated every 8 weeks.
- Early Objective Response Rate (EOR) is defined as the percentage of patients, relative to the total of the enrolled subjects, achieving a ≥20% decrease in the sum of diameters of RECIST target lesions at week 8 compared to baseline.
- Depth of Response (DpR) is defined as the relative change in the sum of longest diameters of RECIST target lesions at the nadir, in the absence of new lesions or progression of non-target lesions, when compared with baseline.

- Overall survival (OS) is defined as the time from randomization to the date of death due to any cause. For patients still alive at the time of analysis, the OS time will be censored on the last date the patients were known to be alive.
- Quality of Life (QoL) assessed using the EORTC QLQ-C30 and the EORTC QLQ-CR29 questionnaires, will be evaluated from patients who have completed at least one questionnaire item at baseline and during the study period according to the arm they were assigned to by randomization through descriptive summary statistics.
- Time To Deterioration in Quality of Life (TTD) is defined as the time from baseline to the first onset of a 10-point or greater decrease from baseline for functional scales or a 10-point or greater increase for symptom scales or death.
