Efficacy

For patients with previously treated metastatic GEJ or gastric cancer, help extend survival with LONSURF3,4,5

LONSURF® (FTD/TPI) tablets was studied in the TAGS trial3,4

LONSURF was studied in 507 patients with previously treated metastatic gastroesophageal junction (GEJ) or gastric cancer in the TAGS (TAS-102 Gastric Study) trial, a multinational, randomized, double-blind, placebo-controlled, phase 3 trial.3,4

Patients had received at least 2 prior regimens, including fluoropyrimidine, platinum agent, taxane and/or irinotecan, and HER2 therapy (in patients with HER2-positive tumors) and were refractory to or intolerant of the last prior therapy. 44% of patients taking LONSURF had undergone a previous gastrectomy.4

The primary endpoint in the TAGS trial was overall survival (OS), defined as the time (in months) from randomization until death. A key secondary endpoint was progression-free survival (PFS), defined as the time (in months) from randomization to the first radiologic confirmation of disease events from any cause. Another secondary endpoint was median time to deterioration of ECOG performance status defined as the time (in months) from randomization until the first date on which an ECOG Performance Status score of ≥ 2 was recorded.4,5

In the TAGS trial, LONSURF provided a statistically significant reduction in risk of mortality (31%)3,4,5

ECOG Performance Status6

Results were based on the ECOG performance status scale.

  • Grade 0 = fully active and able to carry on all pre-disease performance without restriction
  • Grade 1 = restricted in physically strenuous activity, but ambulatory and able to carry out work of a light or sedentary nature, e.g., light housework, office work
  • Grade 2 = ambulatory and capable of all self care, but unable to carry out any work activities; up and about >50% of waking hours
  • Grade 3 = capable of only limited self care and confined to a bed or chair >50% of waking hours
  • Grade 4 = completely disabled and cannot carry on any self care and totally confined to a bed or chair

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Severe Myelosuppression: LONSURF caused severe and life‑threatening myelosuppression (Grade 3‑4) consisting of neutropenia (38%), anemia (18%), thrombocytopenia (5%), and febrile neutropenia (3%). Two patients (0.2%) died due to neutropenic infection. A total of 12% 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, absolute neutrophil count less than 500/mm3, 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 and for at least 6 months after the final dose.

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 (46% vs 32%), Grade 3 anemia (22% vs 16%), and Grade 3 or 4 thrombocytopenia (7% vs 4%).

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. 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.

Renal Impairment: No adjustment to the starting dosage of LONSURF is recommended in patients with mild or moderate renal impairment (CLcr of 30 to 89 mL/min). Patients with severe renal impairment (CLcr < 30 mL/min) were not studied.

ADVERSE REACTIONS

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 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%), infections (27% vs 16%), abdominal pain (21% vs 18%), pyrexia (19% vs 14%), stomatitis (8% vs 6%), dysgeusia (7% vs 2%), and alopecia (7% vs 1%). In metastatic gastric cancer or gastroesophageal junction (GEJ), the most common adverse drug reactions, respectively were, nausea (37% vs 32%), decreased appetite (34% vs 31%), vomiting (25% vs 20%), infections (23% vs 16%) and diarrhea (23% vs 14%).

Pulmonary emboli occurred more frequently in LONSURF‑treated patients compared to placebo: (2% vs 0%) in mCRC and (3% vs 2%) in metastatic gastric cancer and GEJ.

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 mCRC, respectively, were anemia (77% vs 33%), neutropenia (67% vs 1%), and thrombocytopenia (42% vs 8%). In metastatic gastric cancer or GEJ, the test abnormalities, respectively, were neutropenia (66% vs 4%), anemia (63% vs 38%), and thrombocytopenia (34% vs 9%).
