Korábbi kezelés

• Treatment of metastases greater than 3 cm with radio-frequency/microwave ablation within 24 months prior to study entry if applicable.
• Treatment of metastases greater than 5 cm with radiation (stereotactic/ brachytherapy) within 24 months prior to study entry if applicable.

  • A total duration of oxaliplatin-based therapy of six months (i.e. 12 cycles of FOLFOX / FOLFOXIRI or 8 cycles CAPOX) is not exceeded - including therapy within the FIRE-9/PORT trial
  • If already more than three months of oxaliplatin-based therapy (i.e. \>6 cycles of FOLFOX / FOLFOXIRI or \>4 cycles CAPOX) was used, the study therapy should be started with an irinotecan-based regimen (i.e. FOLFIRI or FOLFOXIRI) However, in the case of FOLFOXIRI therapy in the trial, the above mention regulation concerning the total dosing of oxaliplatin still applies (i.e. 12 cycles of FOLFOX / FOLFOXIRI or 8 cycles CAPOX should not be exceeded - including therapy within the FIRE-9/PORT trial).

• Known alcohol or drug abuse.
• Participation in a clinical trial or experimental drug treatment within 28 days prior to potential inclusion in the clinical trial or within a period of 5 half-lives of the substances administered in a clinical trial or during an experimental drug treatment prior to potential inclusion in the clinical trial, depending on which period is longest, or simultaneous participation in another clinical trial while taking part in this clinical trial.
• Concomitant administration of strong CYP3A4 and/or UGT1A1 inducers (e.g. Rifampicin, Carbamazepin, Phenobarbital, Phenytoin or Apalutamid).
• Planned inoculation/vaccination with a live vaccine during treatment with Oxaliplatin and/or Irinotecan, and until 6 months after treatment with Irinotecan.

• Peripheral sensitive neuropathy with functional impairment (\> grade 1 acc. to CTCAE version 5.0 (see appendix 2)).
• Inflammatory bowel disease and/or bowel obstruction.
• Medical history of malignant disease other than mCRC with the following exceptions:
  • patients who have been disease-free for at least three years before randomization
  • patients with adequately treated and completely resected basal cell or squamous cell skin cancer, in situ cervical, breast or prostate cancer, stage I uterine cancer
  • patients with any treated or untreated malignant disease that is associated with a 5-year survival prognosis of ≥ 90% and does not require active therapy
• Suspected SARS-CoV-2 infection with or without symptoms (evaluation according to local policy in respective center with respect to actual status of pandemic and with reference to the policy that would apply to patients with similar therapy outside the trial). This may include assessment of vaccination status, anamnesis, physical examination and potentially antigen and/or PCR testing.

Laborértékek

• Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications.

Egyéb

• Ongoing toxicities \> grade 2 NCI CTCAE
• Severe chronic non-healing wounds, ulcerous lesions or untreated bone fracture.

• Histologically confirmed adenocarcinoma of the colon or rectum.
• Resected (R0 or R1) and/or effectively treated metastases (all techniques allowed) of colorectal cancer within 3-10 weeks before randomization (earlier randomisation allowed if at least 3 weeks interval between intervention and treatment start is guaranteed) AND resected primary tumor (synchronous or metachronous). In cases of synchronous metastases the interval of 3-10 weeks might be calculated following the removal of the primary tumor if this intervention was the last to address all tumor lesions.
• Absence of significant active wound healing complications (if applicable) at randomization. Resolved wound healing complications after resection/ablation are acceptable for inclusion into the trial.
• No radiographic evidence of active metastatic disease at study entry in a CT and/or MRI scan not older than 10 weeks prior randomization. Pre-surgery/ablation images are eligible for the study if all lesions have been addressed in the interval.
• ECOG performance status 0-2.
• 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)

  • Aspartate aminotransferase (AST/GOT) ≤ 3.0 × ULN.

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, hormone-releasing intrauterine devices, and copper intrauterine devices.
  • For men: With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of \< 1% per year during the treatment period and for 6 months after the last dose of study treatment. Men must refrain from donating sperm during this same period.
