The purpose of this study is to collect additional safety and efficacy data during treatment with trifluridine / tipiracil in patients with a pretreated metastatic colorectal cancer (mCRC).
Eligible patients may receive an early access to trifluridine / tipiracil through this clinical study until progression of disease, unacceptable toxicity, investigator decision, patient refusal or until market authorization or reimbursement has been granted by the relevant Authority of the country where that patient is treated or until trifluridine / tipiracil is available by a doctor's prescription or can be accessed from another source or Sponsor decision.

Experimental: S95005
Film-coated tablet containing 15 mg of trifluridine and 7.065 mg of tipiracil hydrochloride, or 20 mg of trifluridine and 9.42 mg of tipiracil hydrochloride, taken orally twice a day at the dose of 35 mg/m²/dose. The treatment is given until progression of disease, unacceptable toxicity, investigator decision, patient refusal or until market authorization or reimbursement has been granted by the relevant Authority of the country where that patient is treated or until trifluridine / tipiracil is available by a doctor's prescription or can be accessed from another source or Sponsor decision.

Inclusion Criteria:
- Male or Female participant aged ≥18 years old.
- Has definitive histologically confirmed adenocarcinoma of the colon or rectum.
- Has metastatic lesion(s).
- Has received at least 2 prior regimens of standard chemotherapies (including fluoropyrimidines, irinotecan, oxaliplatin, an anti-VEGF monoclonal antibody and at least one of the anti-EGFR monoclonal antibodies for RAS wild-type patients) for mCRC and is refractory or intolerant to those chemotherapies or is not candidate for those chemotherapies.

Female participants of childbearing potential and male participants with partners of childbearing potential must agree to use a highly effective method of birth control during the study and for 6 months after the discontinuation of study medication. Women and female partners using hormonal contraceptive must also use a barrier method.
Exclusion Criteria:

- Eligible for enrolment into another available ongoing clinical study of trifluridine / tipiracil.
- Has previously received trifluridine / tipiracil or hypersensitivity to the active substances or to any of the excipients of trifluridine / tipiracil.
- Has rare hereditary problems of galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption.
- Has certain serious illness or medical condition(s) described in the protocol.
- Has had certain other recent treatment e.g. major surgery, anticancer therapy, radiation therapy, participation in another interventional study, within the specified time frames prior to first day of study drug administration.
- Has unresolved toxicity of greater than or equal to Common Terminology Criteria for Adverse Events (CTCAE) Grade 2 attributed to any prior therapies (excluding anemia, alopecia, skin pigmentation, and platinum-induced neurotoxicity).
