More options are needed for the treatment of refractory mCRC
Based on SEER data, 20% of colorectal cancer cases diagnosed between 2004 and 2010 were metastatic at diagnosis. 5‑year survival for these patients was 12.9%.1*
“Given the current limited treatment options, mCRC patients who are refractory to standard therapy would benefit from the availability of additional treatment options. LONSURF represents such an option in this area of high unmet medical need.”2
Data source: Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute.
*SEER 18 areas (San Francisco, Connecticut, Detroit, Hawaii, Iowa, New Mexico, Seattle, Utah, Atlanta, San Jose-Monterey, Los Angeles, Alaska Native Registry, Rural Georgia, California excluding SF/SJM/LA, Kentucky, Louisiana, New Jersey, and Georgia excluding ATL/RG). Based on follow‑up of 211,799 patients into 2011.1
LONSURF: The first and only oral oncolytic combination tablet for your patients with refractory mCRC3
LONSURF® (trifluridine and tipiracil) tablets are indicated for the treatment of patients with metastatic colorectal cancer (mCRC) who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan‑based chemotherapy, an anti‑VEGF biological therapy, and if RAS wild type, an anti‑EGFR therapy.3
The efficacy and safety profile of LONSURF were studied in RECOURSE, an international, randomized, double‑blind, placebo-controlled phase 3 trial involving 800 patients with previously‑treated mCRC.3,4 All patients had KRAS wild‑type or mutated tumors.3
In the trial, randomized patients received at least 2 prior regimens of standard chemotherapy and were refractory to or were failing all of the therapies mentioned above within 3 months.3,4 Disease progression was based on imaging during or within 3 months of the last administration of each of the standard chemotherapies.2
Mechanism of Action
An oral oncolytic combination tablet that interferes with the DNA of tumor cells* to inhibit proliferation3,4,5
LONSURF mechanism of action3-7
- Uses a dual approach to inhibit rapid degradation of trifluridine and subsequently tumor growth
- Demonstrated anti‑tumor activity against KRAS wild‑type and mutated human colorectal cancer xenografts in mice
Learn about the components of LONSURF, and how they work together:
LONSURF® (trifluridine and tipiracil) tablets consist of a thymidine‑based nucleoside analog, trifluridine, and the thymidine phosphorylase inhibitor, tipiracil, at a molar ratio 1:0.5 (weight ratio, 1:0.471). Inclusion of tipiracil increases trifluridine exposure by inhibiting its metabolism by thymidine phosphorylase.
Following uptake into cancer cells, trifluridine, in its triphosphate form (FTD‑TP), is incorporated into the DNA, interferes with DNA function, and inhibits cell proliferation. No enzyme has been identified for the dephosphorylation of FTD‑TP, which may explain its incorporation into DNA.
Trifluridine/tipiracil demonstrated anti‑tumor activity against KRAS wild‑type and mutant human colorectal cancer xenografts in mice.3

WARNINGS AND PRECAUTIONS
Severe Myelosuppression: In Study 1, LONSURF caused severe and life‑threatening myelosuppression (Grade 3‑4) consisting of anemia (18%), neutropenia (38%), thrombocytopenia (5%), and febrile neutropenia (3.8%). One patient (0.2%) died due to neutropenic infection. In Study 1, 9.4% of LONSURF‑treated patients received granulocyte‑colony stimulating factors.
Obtain complete blood counts prior to and on day 15 of each cycle of LONSURF and more frequently as clinically indicated. Withhold LONSURF for febrile neutropenia, Grade 4 neutropenia, or platelets less than 50,000/mm3. Upon recovery, resume LONSURF at a reduced dose as clinically indicated.
Embryo‑Fetal Toxicity: LONSURF can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with LONSURF.
USE IN SPECIFIC POPULATIONS
Lactation: It is not known whether LONSURF or its metabolites are present in human milk. There are no data to assess the effects of LONSURF or its metabolites on the breast‑fed infant or the effects on milk production. Because of the potential for serious adverse reactions in breast‑fed infants, advise women not to breastfeed during treatment with LONSURF and for 1 day following the final dose.
Male Contraception: Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use condoms during treatment with LONSURF and for at least 3 months after the final dose.
Geriatric Use: Patients 65 years of age or over who received LONSURF had a higher incidence of the following compared to patients younger than 65 years: Grade 3 or 4 neutropenia (48% vs 30%), Grade 3 anemia (26% vs 12%), and Grade 3 or 4 thrombocytopenia (9% vs 2%).
Hepatic Impairment: Patients with severe hepatic impairment (total bilirubin greater than 3 times ULN and any AST) were not studied. No adjustment to the starting dose of LONSURF is recommended for patients with mild hepatic impairment. Do not initiate LONSURF in patients with baseline moderate or severe (total bilirubin greater than 1.5 times ULN and any AST) hepatic impairment.
Renal Impairment: In Study 1, patients with moderate renal impairment (CLcr=30 to 59 mL/min, n=47) had a higher incidence (difference of at least 5%) of ≥Grade 3 adverse events, serious adverse events, and dose delays and reductions compared to patients with normal renal function (CLcr ≥90 mL/min, n=306) or patients with mild renal impairment (CLcr=60 to 89 mL/min, n=178).
Patients with moderate renal impairment may require dose modifications for increased toxicity. Patients with severe renal impairment were not studied.
Most Common Adverse Drug Reactions in Patients Treated With LONSURF (≥5%): The most common adverse drug reactions in LONSURF‑treated patients vs placebo‑treated patients with refractory mCRC, respectively, were asthenia/fatigue (52% vs 35%), nausea (48% vs 24%), decreased appetite (39% vs 29%), diarrhea (32% vs 12%), vomiting (28% vs 14%), abdominal pain (21% vs 18%), pyrexia (19% vs 14%), stomatitis (8% vs 6%), dysgeusia (7% vs 2%), and alopecia (7% vs 1%).
Additional Important Adverse Drug Reactions: The following occurred more frequently in LONSURF‑treated patients compared to placebo: infections (27% vs 15%) and pulmonary emboli (2% vs 0%).
The most commonly reported infections which occurred more frequently in LONSURF‑treated patients were nasopharyngitis (4% vs 2%) and urinary tract infections (4% vs 2%).
Interstitial lung disease (0.2%), including fatalities, has been reported in clinical studies and clinical practice settings in Asia.
Laboratory Test Abnormalities in Patients Treated With LONSURF: Laboratory test abnormalities in LONSURF‑treated patients vs placebo-treated patients with refractory mCRC, respectively, were anemia (77% vs 33%), neutropenia (67% vs 1%), and thrombocytopenia (42% vs 8%).Please see full Prescribing Information.
