Detailed Description
This is a prospective, open-label, multicentric phase II randomized in a 1:2 ratio trial in which patients initially unresectable and previously untreated mCRC will receive induction treatment with FOLFOXIRI plus bev up to 8 cycles followed by maintenance with 5-FU/LV plus bev until disease progression, unacceptable toxicity or patient's refusal (arm A) versus FOLFOXIRI plus bev plus atezolizumab up to 8 cycles followed by maintenance with 5-FU/LV plus bev plus atezolizumab until disease progression, unacceptable toxicity or patient's refusal (arm B). If disease progression does not occur during induction, at the treating physician's discretion, the reintroduction after progression of the same induction treatment (up to 8 cycles) according to randomization arm, followed by maintenance until disease progression, unacceptable toxicity or patient's refusal, is recommended.
The third- and subsequent lines of treatment will be at investigators' choice.

Time Frame |
---|---|---|
Overall toxicity rate

24 months
|
Toxicity rate
Time Frame: 24 months
|
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 4.0), during the induction and the maintenance phases of treatment.
|
24 months

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 criteria, 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.
|
16 months
|
Early Objective Response Rate (EOR)
Time Frame: 16 months
|
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.
|
16 months
|
Deepness of response (DoR)
Time Frame: 16 months

|
Progression Free Survival 2 (PFS2) is defined as beginning with randomization and ending with the first of the following events: a) death; b) disease progression according to RECIST 1.1 criteria on any treatment given after 1st progression. For patients that will not receive any treatment within 3 months after 1st progression, PFS2 will be equal to PFS. Censoring rules for PFS2 will be: end of study without PD, loss at follow-up. Curative surgery for metastasis will not result in censoring for PFS2. PFS2 will be analyzed both in the intention-to-treat population (whichever 2nd-line treatment will be adopted) and in the per-protocol population. |

2nd-PFS will be censored on the date of the last evaluable on study tumor assessment documenting absence of progressive disease for patients who are alive, on study and 2nd-progression free at the time of the analysis.
2nd-PFS will be analyzed both in the intention-to-treat population (whichever 2nd-line treatment will be adopted) and in the per-protocol population.
