Inclusion Criteria

1.Patient’s signed informed consent
2.Patients = 18 years at the time of signing the informed consent
3.Histologically confirmed adenocarcinoma of the colon or rectum (appendix carcinoma is excluded)
4.Metastatic colorectal cancer (mCRC) with at least one measurable lesion according to RECIST 1.1 in a computed tomography (CT) or magnetic resonance imaging (MRI) scan performed within 5 weeks prior to randomisation
5.Metastases are primarily unresectable or patient is unable/unwilling to undergo surgery
6.RAS wild-type (KRAS, exons 2, 3, 4 and NRAS, exons 2, 3, 4) mCRC, proven in the primary tumor or metastasis. The RAS mutational status must be determined by means of a validated test method.
7.Patient is not eligible to undergo combination chemotherapy according to investigator’s assessment or unwilling to undergo combination chemotherapy.
8.ECOG performance status 0-2
9.Adequate bone marrow, hepatic and renal organ function, defined by the following laboratory test results:
•Absolute neutrophil count ? 1.5 x 109/L (1500/µL)
•Hemoglobin = 80 g/L (8 g/dL)
•Platelet count = 75 x109/L (75,000/µL) without transfusion
•Total serum bilirubin of = 1.5 x upper limit of normal (ULN)
•Aspartate aminotransferase (AST/GOT) and alanine aminotransferase (ALT/GPT) = 2.5 × ULN; if liver function abnormalities are due to underlying liver metastasis, AST and ALT = 5 × ULN
•Calculated glomerular filtration rate (GFR) according to Cockcroft –Gault formula or according to MDRD = 30 mL/min or serum creatinine = 1.5 x ULN
•Urine dipstick for proteinuria < 2+ (within 14 days prior to randomisation), unless a subsequent 24-hour urine collection demonstrates < 1 g of protein in 24 hours.
10.Patients without anticoagulation need to present with an INR <1.5 x ULN and PTT <1.5 x ULN. Patients with anticoagulation may be enrolled if the patient receives the medication at a stable dose for at least 2 weeks before randomisation and provided that INR and PTT are <1.5 x ULN.
11.For females of childbearing potential (FCBP): negative pregnancy test within 14 days before randomisation and agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods with a failure rate of <1% per year during the treatment period and for at least 6 months after the last dose of study treatment.
A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (= 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male partner’s sterilization, hormonal contraceptives that inhibit ovulation supplemented with a barrier method, hormone-releasing intrauterine devices, and copper intrauterine devices.
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
12.For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below:
With female partners of childbearing potential, men must remain abstinent or use a condom plus a

Exclusion Criteria

1.Prior systemic therapy of metastatic disease.
Note: Prior adjuvant chemotherapy is permitted, if completed > 3 months prior to randomisation. Multimodal treatment of rectal cancer is not considered anti-metastatic therapy and does not preclude study participation
2.Known brain metastasis. In case of symptoms that are suggestive of brain metastasis, brain metastasis has to be ruled out by means of cranial CT/MRI.
3.Significant cardiovascular disease such as: New York Heart Association Class III or greater heart failure; myocardial infarction within 6 months prior to randomisation; balloon angioplasty (PTCA) with or without stenting within 6 months prior to randomisation; despite anti-arrhythmic therapy unstable cardiac arrhythmia > grade 2 NCI CTCAE; unstable angina pectoris
4.Transient ischaemic attack or cerebrovascular accident within 6 months prior to randomization, history of cerebral or aortic aneurysm or dissection
5.Medical history of deep vein thrombosis or pulmonary embolism within 6 months prior to randomisation or medical history of recurrent thromboembolic events (> 1 episode of deep vein thrombosis, pulmonary embolism, peripheral embolism) within the last 2 years.
6.Severe bleeding event within the last 6 months before randomisation (except tumor bleeding surgically treated by tumor resection)
7.Evidence of bleeding diathesis or significant coagulopathy
8.Uncontrolled hypertension defined as systolic blood pressure =160 mm Hg and/or diastolic = 100 mm Hg under antihypertensive medication
9.Severe chronic non-healing wounds, ulcerous lesions or untreated bone fracture.
10.History of abdominal or tracheoesophageal fistula or gastrointestinal perforation, or intra-abdominal abscess -unrelated to surgery- within 6 months prior to randomisation.
11.Acute or subacute bowel obstruction, active chronic inflammatory bowel disease or chronic diarrhea
12.History of keratitis, ulcerative keratitis or severe dry eye.
13.Hypersensitivity to trifluridine/tipiracil or panitumumab or bevacizumab or any of the excipients, known hypersensitivity to Chinese hamster ovary cell products, known hypersensitivity to human or humanized antibodies
14.Current or recent (within 10 days of randomisation) use of or anticipated need for continuous treatment during study treatment with acetylsalicylic acid ? 325 mg/day or treatment with dipyramidole, ticlopidine > 2 x 250 mg/day, clopidogrel > 75 mg/day, and cilostazol.
Combination of these drugs are not allowed.
15.Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to randomisation, or abdominal surgery, abdominal interventions or significant abdominal traumatic injury within 28 days prior to randomisation or anticipation of need for major surgical procedure during the course of the study or non-recovery from side effects of any such procedure
16.Core biopsy or other minor surgical procedure, excluding placement of a vascular access devices, within 3 days prior to the first dose of bevacizumab
17.History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis/interstitial pneumonia, or idiopathic pneumonitis/interstitial pneumonia, or evidence of active pneumonitis or pulmonary fibrosis on screening chest imaging
