Perioperative Treatment of Resectable Liver Metastases (PERIMAX)

This is an interventional treatment trial for Colon Cancer Liver Metastasis focused on measuring Colorectal cancer, Liver metastases, Perioperative treatment, Liver resection Read More

Main selection criteria:

1. Histological proven CRC with completely resectable metachronous or synchronous liver metastases (as judged by the treating surgeon).
2. Patients must have undergone complete resection (R0) of the primary tumor at least 4 weeks before randomization. Or in case of synchronous disease with intact primary; the primary tumor have to be R0 resectable together with the liver metastases and the patient has a non-obstructive primary tumor and is able to receive preoperative chemotherapy before surgery. Synchronous rectal primary is not allowed.
3. Measurable hepatic disease by Response Evaluation Criteria in Solid Tumors (RECIST version 1.1).
4. No evidence of extra-hepatic metastasis of CRC.
5. Patients must be from 18 to 75 years.
6. ECOG Performance status ≤ 1
7. No previous chemotherapy for metastatic disease. Radiotherapy alone is allowed if given pre or post protocol treatment.
8. Previous adjuvant chemotherapy for primary CRC is allowed if completed at least 6 months before inclusion in this study.

9. All the following tests should be done within 4 weeks prior to randomization

   • Absolute neutrophil count > 1.5 x 109/L, platelets > 100 x 109/L, and hemoglobin > 9 g/dL or 5.59 mmol/l.
   • Serum creatinine less than 1.5 times the upper limit of normal (ULN) (to exclude severe renal impairment); no significant proteinuria (urine dipstick for proteinuria ³ 2+. If urine dipstick is ³ 2+, 24-hour urine must demonstrate £ 1 g of protein in 24 hours for patient to be eligible).
   • Absence of major hepatic insufficiency (bilirubin < 1.5 x ULN and aspartate aminotransferase (ASAT)/alanine aminotransferase (ALAT) < 5 x ULN).
   • Patients not receiving therapeutic anticoagulation must have an INR < 1.5 ULN and aPTT < 1.5 ULN within 7 days prior to registration. The use of full dose anticoagulants is allowed as long as the INR or aPTT is within therapeutic limits (according to the medical standard in the institution) and the patient has been on a stable dose for anticoagulants for at least two weeks at the time of registration.
10. No pregnancy or breast feeding. Negative serum pregnancy test within 7 days of starting study treatment in pre-menopausal women and women < 1 year after the onset of menopause is required before entering in the trial. Note: a negative test has to be reconfirmed by a urine test, should the 7-day window be exceeded.
11. Adequate contraception is required during and for 3 months after study treatment for both male and female patients if the risk of conception exists.
12. No major surgical procedure, open biopsy, or significant traumatic injury within 4 weeks prior to randomization.
13. No previous exposure to VEGF/VEGFR-targeting therapy within the last 12 months.
14. No thrombosis or severe bleeding within 6 months prior to entry into the study (except for bleeding of the tumor before its surgical resection) and no evidence of bleeding diathesis or coagulopathy.
15. Absence of peripheral neuropathy NCI CTCAE-grade ≥ 1, active inflammatory bowel disease or other bowel disease causing chronic diarrhea (defined as > 4 loose stools per day), serious wound complications, ulcers, or bone fractures.
16. No evidence of any other disease, metabolic dysfunction, physical examination finding or laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or puts the patient at high risk for treatment-related complications.
17. No concomitant treatment with ASS > 325 mg or NSAIDs, known to inhibit platelet function, sorivudin or analog compounds or preparations of St. John's wort.
