简要总结
This is an open-label, prospective, randomized, multicenter phase II trial that will evaluate the efficacy and safety of intermittent addition of cetuximab to a FOLFIRI-based first line therapy to patients with RAS (Rat sarcoma)-mutant mCRC (Metastatic colorectal cancer) diagnosis who convert to RAS wild-type using monitoring of the RAS mutation status by liquid biopsy.

入选标准
- •Histologically confirmed, UICC stage IV adenocarcinoma of the left-sided colon or rectum with metastases (metastatic colorectal cancer), primarily non-resectable, confirmed RAS mutations proven in the primary tumor or metastasis (KRAS ans NRAS exon 2, 3, 4)
- •Age ≥ 18 years on day of signing informed consent
- •No previous chemotherapy for metastatic disease (1- 2 cycles FOLFIRI or mFOLFIRI are permitted before enrolment until RAS status is determined)
- •Patients suitable for chemotherapy administration
- •ECOG (Eastern Cooperative Oncology Group) status 0-1
- •Consent to liquid biopsy and mutation analysis
- •Estimated life expectancy > 3 months
- •Presence of at least one measurable reference lesion according to the RECIST 1.1 criteria (chest CT and abdominal CT 4 weeks or less before enrollment)
- •Adequate bone marrow function defined as: Leukocytes 3.0 x 10 9/L with neutrophils 1.5 x 10 9/L, Thrombocytes 100 x 10 9/L, Hemoglobin 9 g/dL
- •Adequate hepatic function defined as: Serum bilirubin 1.5 x ULN (Upper limit of normal), ALAT (Alanine-aminotransferase (= SGPT = serum glutamate pyruvate transaminase) and ASAT (aspartate-aminotransferase (= SGOT = serum glutamate oxalacetate transaminase) 2.5 x ULN (Upper limit of normal) (in the presence of hepatic metastases, ALAT and ASAT 5 x ULN)
- •Adequate renal function: Creatinine clearance ≥ 50 mL/min
- •Adequate cardiac function defined as Normal ECG and echocardiogram with a left ventricular ejection fraction (LVEF) of 55%
- •INR (International normalized ratio) < 1.5 and aPTT (activated Partial thromboplastin time) < 1.5 x ULN (patients without anticoagulation). Therapeutic anticoagulation is allowed if INR and aPTT have remained stable within the therapeutic range for at least 2 weeks.
- •Time interval of at least 6 months since last administration of any previous neoadjuvant/adjuvant chemotherapy or radiochemotherapy of the primary tumor in curative treatment intention to start of 1st line treatment
- •Any relevant toxicities of prior treatments must have resolved to grade ≤ 1 according to the CTCAE (version 5), except alopecia
- •Women of childbearing potential (WOCBP) should have a negative urine pregnancy test within 72 hours prior to receiving the first dose of study medication.
- •Highly effective contraception for both male and female patients throughout the study and for at least 3 months after last dose of study medication administration if the risk of conception exists. Highly effective contraception has to be in line with the definition of the CTFG (Clinical Trial Facilitation Group) recommendation
- •Signed written informed consent and capacity of understanding the informed consent
排除标准
- •Right sided mCRC
- •Primarily resectable metastases
- •Previous chemotherapy for the colorectal cancer with the exception of adjuvant treatment, completed at least 6 months before entering the study (1- 2 cycles FOLFIRI or mFOLFIRI are permitted before enrolment)

- •Active infection with hepatitis B or C
- •Medical or psychological impairments associated with restricted ability to give consent or not allowing conduct of the study
- •Additional cancer; Exceptions include adequately treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy without evidence of recurrence
- •Uncontrolled hypertension
- •Marked proteinuria (nephrotic syndrome)
- •Arterial thromboembolism or severe hemorrhage within 6 months prior to randomization (with the exception of tumor bleeding before tumor resection surgery)
- •Hemorrhagic diathesis or tendency towards thrombosis
- •Participation in a clinical study or experimental drug treatment within 30 days prior to study
- •Known hypersensitivity or allergic reaction to any of the study medications
- •Severe, non-healing wounds, ulcers, bone fractures or an infection requiring systemic therapy
- •Known history of alcohol or drug abuse
- •Complete dihydropyrimidine dehydrogenase (DPD) deficiency (phenotype and/or genotype test) (Patients with partial DPD deficiency may be included in this clinical trial at the discretion of the investigator and should receive a reduced starting 5-FU dose)
- •Known glucuronidation deficiency (Gilbert's syndrome) (specific screening not required)
- •Absent or restricted legal capacity
- •For female patients only: Pregnancy (absence to be confirmed by ß-HCG test) or lactating

FOLFIRI + cetuximab
Experimental
Patients in Arm A will receive FOLFIRI + cetuximab until progressive disease (PD), unacceptable toxicity, withdrawal of informed consent or death, whatever occurs first. The recurrence of RAS-mutation without PD to switch back to FOLFIRI. In case of repeated conversion to RAS wild-type without PD, treatment will shift to FOLFIRI + cetuximab again, and so on. Switches of treatment will proceed until progressive disease (PD), unacceptable toxicity, withdrawal of informed consent or death, whatever occurs first.
