Indicated for metastatic colorectal cancer in patients previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF biological therapy, and if RAS wild-type, an anti-EGFR therapy
Dose is based on trifluridine component rounded to the nearest 5-mg increment
35 mg/m² PO BID on Days 1-5 and Days 8-12 of each 28-day cycle; not to exceed 80 mg/dose
Administer within 1 hr of completion of morning and evening meals
Administer until disease progression or unacceptable toxicity
Obtain CBC counts prior to and on Day 15 of each cycle
Do not initiate the cycle until
- ANC ≥1500/mm³ or febrile neutropenia is resolved
- Platelets ≥75,000/mm³ grade 3 or 4 nonhematological adverse reactions are resolved to Grade 0 or 1
Within a treatment cycle, withhold for any of the following
- ANC <500/mm³ or febrile neutropenia
- Platelets <50,000/mm³ grade 3 or 4 nonhematological adverse reactions
Resume drug with reduced dose
- After recovery, resume drug after reducing the dose by 5 mg/m²/dose from the previous dose level, if the following occur
- Febrile neutropenia
- Uncomplicated grade 4 neutropenia (which has recovered to ≥1500/mm³) or thrombocytopenia (which has recovered to ≥75,000/mm³) that results >1 week delay in start of next cycle
- Nonhematologic grade 3 or 4 adverse reaction, except for grade 3 nausea and/or vomiting controlled by antiemetic therapy or grade 3 diarrhea responsive to antidiarrheal medication

- Mild (total bilirubin [TB] ≤ULN and AST >ULN, or TB <1-1.5 xULN and any AST): No dosage adjustment required
- Moderate-to-severe: Not studied
- Mild-to-moderate (CrCl 30-89 mL/min): No dosage adjustment required; however, patients with moderate impairment (30-59 mL/min) may require dose modification for increased toxicity

Safety and efficacy not established
Based on animal studies and its mechanism of action, trifluridine/tipiracil can cause fetal harm when administered to pregnant women
Caused embryo-fetal lethality and embryo-fetal toxicity in pregnant rats when orally administered during gestation at dose levels resulting in exposures lower than those achieved at the recommended dose of 35 mg/m² BID
Advise pregnant women of the potential risk to the fetus
Advise females of reproductive potential to use effective contraception during treatment
Unknown if distributed in human breast milk
In nursing rats, trifluridine and tipiracil or their metabolites were present in breast milk
Because of the potential for serious adverse reactions in breastfeeding infants, advise women not to breastfeed during treatment and for 1 day following the final dose
A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA:Information not available.
What Is Tipiracil-trifluridine?
Tipiracil and trifluridine is a combination cancer medicine that interferes with the growth and spread of cancer cells in the body.
Tipiracil and trifluridine is used to treat colorectal cancer that has spread to other parts of the body (metastatic).
Tipiracil and trifluridine is usually given after other cancer medicines have been tried without success.
