Study Summary

This is a multicentric single arm, open label trial. In this study patients candidated to a first line of chemotherapy for metastatic colorectal cancer will be treated with 8 cycles of folfoxiri plus bevacizumab plus nivolumab followed by a maintenance with bevacizumab plus nivolumab.

Patients who do not progress during chemotherapy phase will receive bevacizumab plus nivolumab as maintenance therapy.

Patients will be treated until disease progression, unacceptable toxicity or patient/physician decision.

Availability at baseline of a representative formalin-fixed, paraffin-embedded (FFPE) diagnostic tumor specimen, as primary and/or metastatic tumor tissue block oras fifteen 5-micron unstained slides are allowed (the neoplastic cell content ofeach tumor sample will be assessed and in those cases with neoplastic cells <50% amacro-dissection of the specimen will be performed, if possible).

  11. If DPD status is known it must be wild type. No restriction are applied if DPDstatus in unknown.

  12. Women of childbearing potential must have a negative blood pregnancy test within 24hr prior to the start of study drug. For this trial, women of childbearing potentialare defined as all women after puberty, unless they are postmenopausal for at least 12 months, are surgically sterile, or are sexually inactive.

  13. Subjects and their partners must be willing to avoid pregnancy during the trial anduntil 5 months for WOCBP (Women of Childbearing Potential) and 7 months for malesubjects with female partners of WOCBP after the last trial treatment. Male subjectswith female partners of childbearing potential and female subjects of childbearingpotential must, therefore, be willing to use adequate contraception as approved bythe investigator (barriers contraceptive measure or oral contraception).

Exclusion

Exclusion Criteria:

  1. Prior chemotherapy, excluded patient treated in neo/adjuvant setting at least 12months before diagnosis of metastatic disease.

  2. Radiotherapy to any site within 4 weeks before the study.

  3. Serious, non-healing wound, ulcer, or bone fracture.

  4. Evidence of bleeding diathesis or coagulopathy.

  5. Uncontrolled hypertension and prior history of hypertensive crisis or hypertensiveencephalopathy.

  6. Systemic corticosteroids within 2 weeks of the first dose of nivolumab.

  7. Diagnosis of immunodeficiency or is receiving systemic steroid therapy or any otherform of immunosuppressive therapy within 14 days prior to the first dose of trialtreatment.

  8. Additional malignancy in the last 5 years. Exceptions include basal cell carcinomaof the skin, squamous cell carcinoma of the skin, or in situ cervical cancer thathas undergone potentially curative therapy.

  9. Active and untreated brain (CNS) metastases and/or carcinomatous meningitis.Subjects with previously treated brain metastases may participate provided they arenot using steroids for at least 7 days prior to trial treatment.

  10. Any active or recent history of a known or suspected autoimmune disease or recenthistory of a syndrome that required systemic corticosteroids (> 10 mg dailyprednisone equivalent) or immunosuppressive medications except for syndromes whichwould not be expected to recur in the absence of an external trigger.

  11. Evidence of interstitial lung disease, active non-infectious pneumonitis, or ahistory of grade 3 or greater pneumonitis.

  12. Active infection requiring systemic therapy.

  13. History of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).

  14. Any positive test for hepatitis B or hepatitis C virus indicating acute or chronicinfection.

  15. Live vaccine within 30 days prior to the first dose of trial treatment.

  16. Chronic, daily treatment with high-dose aspirin (>325 mg/day).

  17. Significant vascular disease (e.g. aortic aneurysm requiring surgical repair orrecent arterial thrombosis) within 6 months of study enrolment.

  18. Any previous venous thromboembolism > NCI CTCAE Grade 3.

  19. History of abdominal fistula, GI perforation, intra-abdominal abscess or active GIbleeding within 6 months prior to the first study treatment.

  20. Current or recent (within 10 days prior to study treatment start) ongoing treatmentwith anticoagulants for therapeutic purposes.

  21. Major surgical procedure, open biopsy, or significant traumatic injury within 28days prior to study treatment start, or anticipation of the need for major surgicalprocedure during the course of the study.

  22. Presence of colic prosthesis or stent.

  23. History of any severe hypersensitivity reactions to any monoclonal antibody.

  24. Women of childbearing potential who are pregnant or breastfeeding.

Study Description

This is a prospective, open-label, multicentric phase II trial in which patients with metastatic colorectal cancer RASm/BRAFm patients will receive nivolumab in combination with FOLFOXIRI/Bevacizumab as first line chemotherapy.

Study screening will take place within 28 days prior to initiation of study treatment. At screening, every patient must have local RAS/BRAF known status. A centralized review of RAS/BRAF status will be performed during the study.

Eligible patients will be enrolled and begin treatment with FOLFOXIRI/bevacizumab plus nivolumab every 2 weeks for 8 cycles followed by maintenance with bevacizumab plus nivolumab every 2 weeks until disease progression, unacceptable toxicity or patient/physician decision. Bevacizumab will be administered intravenously at dose of 5 mg/kg every 2 weeks. Nivolumab will be administered intravenously at flat dose of 240 mg every 2 weeks.

Folfoxiri will be administered as 165 mg/m2 intravenous infusion of irinotecan for 60 min, followed by an 85 mg/m2 intravenous infusion of oxaliplatin given concurrently with leucovorin at a dose of 200 mg/m2 for 120 min, followed by a 3200 mg/m2 continuous infusion of fluorouracil for 48 h.

During the study treatment period, patients will be followed for safety based on AE assessments including vital signs, physical findings and clinical laboratory test results.

In order to guarantee the safety of the patients, the enrolment will be stopped when the 10th patient will start treatment. An Independent Monitoring Committee will evaluate the safety data of these patients and will decide if the study should be completed, amended or closed.

Efficacy will be evaluated by the investigator according to RECIST v1.1 every 8 weeks during treatment and then every 3 months for 3 years.

During the study baseline tumor blocks will be centrally analysed to determinate inflammatory infiltrate, MSI/MSS and PD-L1 status. The biological characterization and Tumor Mutation Burden (TMB) will be also analysed centrally.

Following discontinuation of study treatment, safety assessments will be conducted 30 days after the last study drug administration or until initiation of other anti-cancer therapy (whichever occurs first). Thereafter, patients will be followed for disease progression (unless this has already occurred), SAEs, anticancer therapy and survival. Follow-up will continue for up to 3 years.

A blood sample will be collected for all patients at baseline, prior to cycle 5, at the end of chemotherapy and at disease progression.

Quality of life will be assessed at baseline, every 4 weeks during treatment and study discontinuation visit.
