Actual body weight should be used for calculating creatinine clearance. For patients with a Body Mass Index (BMI) > 30 kg/m2, lean body weight should be used instead.
You likely can't join if
- Anti-cancer chemotherapy, biologic therapy or any other systemic therapy if administered prior to the first planned dose of study medication within period of time equivalent to the usual cycle length of the regimen. An exception is made for oral fluoropyrimidines (e.g. capecitabine, S-1), where a minimum of 10 days since last dose must be observed prior to the first planned dose of protocol treatment. Radiotherapy, immunotherapy (including immunotherapy administered for non-neoplastic treatment purposes), or investigational agents within four weeks of first planned dose of study medication, with the exception of limited field radiation up to 14 days before randomization.
- Patients with clinically significant ascites or pleural effusions (e.g., requiring fluid removal within 2 months before randomization, and/or frequent or large volume removal, or requiring an indwelling drainage catheter).
- Patients with hereditary non-polyposis colorectal cancer (HNPCC or Lynch syndrome) or familial adenomatous polyposis syndrome (FAP).
- The MSI/MSS status of the tumor must be known prior to randomization. Patients with microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) status will be excluded.
- Known hypersensitivity to fluoropyrimidine or patients who as a result of toxicity had to reduce or stop 5-FU infusion at the dose of 900 mg/m2/day (total 1800 mg/m2/day)
- Known dihydropyrimidine dehydrogenase (DPD) deficiency.

- Other baseline laboratory evaluations, listed in Section 6.0, must be done within 14 days prior to randomization.
- Patients must consent to provision of, and investigator(s) must confirm access to and agree to submit a representative formalin fixed paraffin block of tumor tissue in order that the specific correlative marker assays may be conducted.
- Must have histologically confirmed adenocarcinoma of the colon or rectum that is metastatic (Stage IV). Patients with more than a single primary CRC adenocarcinoma will be excluded.
- Must have failed standard chemotherapy-based regimens containing a fluoropyrimidine, irinotecan and oxaliplatin.
