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, including but not limited to:
  • Simultaneous application of live vaccines during treatment with irinotecan and for at least 6 months after the last dose.
  • 5-FU must not be given in combination with brivudin, sorivudin and analogues to patients homozygous for DPD and patients known with completely missing DPD activity.

Egyéb

• Ileus or directly imminent ileus as assessed by the local study team. Patients with treated and resolved ileus are allowed into the trial.

• Histologically confirmed adenocarcinoma of the colon or upper rectum.
• Confirmed mismatch-repair proficient and/or microsatellite stable tumor. Both Immunohistochemistry and PCR can be used for diagnosis.
• Intent for curative surgery
• Predicted T3 or T4 stage and or nodal positivity (N+) in a computed tomography and/or magnetic resonance imaging scan of the abdomen/pelvis as assessed by the local study team.
  • T3-4 defined as invasion of surrounding tissue structures or organs
  • N+ defined as regional lymph node(s) without fat hilus and short axis diameter of ≥1 cm
• Absence of clear distant metastases assessed by the investigator based on respective routine evaluations within 6 weeks prior to inclusion into the trial (preferred: computed tomography of thorax and abdomen. Alternatively magnetic resonance images, sonography and x-rays might be used for assessment).
• Absence of significant active wound healing including severe chronic non-healing wounds, ulcerous lesions or untreated bone fracture
• 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 (1,500/µL)
  • Hemoglobin ≥ 80 g/L (8 g/dL) with or without transfusion
  • Platelet count ≥ 100 x109/L (100,000/µL) without transfusion
  • Total serum bilirubin of ≤ 1.5 x upper limit of normal (ULN)
  • Aspartate aminotransferase (AST/GOT) ≤ 3.0 × ULN.
  • Calculated glomerular filtration rate (GFR) according to Cockcroft-Gault formula or according to MDRD ≥ 50 mL/min or serum creatinine ≤ 1.5 x ULN
• Patients without anticoagulation need to present with an INR < 1.5 x ULN and PTT < 1.5 x ULN. Patient with prophylactic or therapeutic anticoagulation are allowed into the trial.
• Proficient fluorouracil metabolism as defined:
  • Prior treatment with 5-FU or capecitabine without unusal toxicity or
  • If tested, normal DPD deficiency test according to the standard of the study site or
  • If tested, in patients with DPD deficiency test with a CPIC activity score of 1.0-1.5 fluoropyrimidine dosage should be reduced by 50%
• For women of childbearing potential (WOCBP): negative pregnancy test within 7 days before treatment initiation 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 post-menarcheal, 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, 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.
  • With pregnant female partners, men must remain abstinent or use a condom during the treatment period and for 6 months after the last dose of study medication to avoid exposing the embryo.
