Warnings/Precautions
Hypertension
Fruquintinib can cause hypertension. Hypertension occurred in 450 of 911 (49%) patients with mCRC treated with fruquintinib, including Grade 3-4 events in 19%, and hypertensive crisis in three patients (0.3%). The median time to first onset of hypertension was 14 days from first dose of fruquintinib.
Do not initiate fruquintinib unless blood pressure is adequately controlled. Monitor blood pressure weekly the first month, at least monthly thereafter, and as clinically indicated. Initiate or adjust anti-hypertensive therapy as appropriate. Withhold, reduce dose, or permanently discontinue fruquintinib based on the severity of hypertension.
Hemorrhagic Events
Fruquintinib can cause serious hemorrhagic events, which may be fatal. In 911 patients with mCRC treated with fruquintinib, 6% of patients experienced a gastrointestinal hemorrhage, including 13 patients (1%) with a Grade ≥3 event and 2 patients with fatal hemorrhages.
Permanently discontinue fruquintinib in patients with severe or life-threatening hemorrhage. Monitor the International Normalized Ratio (INR) levels in patients receiving anticoagulants.
Infections
Fruquintinib can cause an increased risk of infections, including fatal infections. In 781 patients treated with fruquintinib across three randomized, placebo-controlled trials, the overall incidence of infections was higher (18% vs. 12%) including for fatal infections (1% vs. 0.3%) as compared to the placebo arms (n=391).
In 911 patients with mCRC treated with fruquintinib, the most common infections were urinary tract infections (6.8%), upper respiratory tract infections (3.2%), and pneumonia (2.5%); fatal infections included pneumonia (0.4%), sepsis (0.2%), bacterial infection (0.1%), lower respiratory tract infection (0.1%), and septic shock (0.1%).
Withhold fruquintinib for Grade 3 or 4 infections, or worsening infection of any grade. Resume fruquintinib at the same dose when the infection has resolved.
Gastrointestinal Perforation
Fruquintinib can cause gastrointestinal perforation. In 911 patients with mCRC treated with fruquintinib, 12 patients (1.3%) experienced a Grade ≥3 gastrointestinal perforation, including one fatal event.
Permanently discontinue fruquintinib in patients who develop gastrointestinal perforation or fistula.
Hepatotoxicity
Fruquintinib can cause liver injury. In 911 patients with mCRC treated with fruquintinib, 48% experienced increased ALT or AST, including Grade ≥3 events in 5%, and fatal events in 0.2%. Median time to first onset of elevated liver enzymes was 29 days from first dose of fruquintinib.
Monitor liver function tests (ALT, AST, and bilirubin) before initiation and periodically throughout treatment with fruquintinib. Temporarily hold and then reduce or permanently discontinue fruquintinib depending on the severity and persistence of hepatotoxicity as manifested by elevated liver function tests.
Proteinuria
Fruquintinib can cause proteinuria. In 911 patients with mCRC treated with fruquintinib, 36% experienced proteinuria and 2.5% of patients experienced Grade ≥3 events. Median time to first onset of proteinuria was 22 days from first dose of fruquintinib.
Monitor for proteinuria before initiation and periodically throughout treatment with fruquintinib. For proteinuria ≥2 g/24 hours, withhold fruquintinib until improvement to ≤Grade 1 proteinuria; then resume fruquintinib at a reduced dose. Discontinue fruquintinib in patients who develop nephrotic syndrome.
Palmar-plantar Erythrodysesthesia (PPE)
Fruquintinib can cause PPE. In 911 patients with mCRC treated with fruquintinib, PPE occurred in 35%, including 8% with Grade 3 events. Median time to first onset of PPE was 19 days from first dose of fruquintinib.
Based on severity, withhold fruquintinib and then resume at the same or reduced dose
Posterior Reversible Encephalopathy Syndrome (PRES)
Fruquintinib can cause PRES, a syndrome of subcortical vasogenic edema diagnosed by characteristic finding on MRI. PRES occurred in one of 911 patients with mCRC treated with fruquintinib.
Perform an evaluation for PRES in any patient presenting with seizures, headache, visual disturbances, confusion, or altered mental function. Discontinue fruquintinib in patients who develop PRES.
Impaired Wound Healing
Impaired wound healing can occur in patients who receive drugs that inhibit the vascular endothelial growth factor (VEGF) signaling pathway. In 911 patients with mCRC treated with fruquintinib, 1 patient experienced a Grade 2 event of wound dehiscence.
Do not administer fruquintinib for at least 2 weeks prior to major surgery.
Do not administer fruquintinib for at least 2 weeks after major surgery and until adequate wound healing. The safety of resumption of fruquintinib after resolution of wound healing complications has not been established.
Arterial Thromboembolic Events
Fruquintinib may increase the risk of arterial thromboembolic events. In 911 patients with mCRC treated with fruquintinib, 7 patients (0.8%) experienced an arterial thromboembolic event; additionally, fruquintinib studies excluded patients with clinically significant cardiovascular disease, uncontrolled hypertension, or with thromboembolic events within the prior 6 months. Initiation of fruquintinib in patients with a recent history of thromboembolic events should be carefully considered. In patients who develop arterial thromboembolism, discontinue fruquintinib.
Allergic Reactions to FD&C Yellow No. 5 (Tartrazine) and No. 6 (Sunset Yellow FCF)
Fruquintinib 1 mg capsules contain FD&C Yellow No. 5 (tartrazine), which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons. Although the overall incidence of FD&C Yellow No. 5 (tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity.
Fruquintinib 1 mg contains FD&C Yellow No. 6 (sunset yellow FCF), which may cause allergic reactions.
Embryo-fetal Toxicity
Based on findings in animal studies and its mechanism of action, fruquintinib can cause fetal harm when administered to pregnant women. In an embryo-fetal developmental study in rats, embryotoxic and teratogenic effects were observed at exposures below the clinical exposure.
Advise pregnant women of the potential risk to a fetus. Advise females of childbearing potential and males with female partners of childbearing potential to use effective contraception during treatment with fruquintinib and for 2 weeks after the last dose.
Specific Populations
Pregnancy
Based on findings in animal studies and its mechanism of action, fruquintinib can cause fetal harm when administered to a pregnant woman. In an embryo-fetal developmental study in pregnant rats, oral administration of fruquintinib during the period of organogenesis resulted in teratogenicity and embryolethality at exposures below the clinical exposure. There are no data on the use of fruquintinib in pregnant women. Advise pregnant women of the potential risk to a fetus.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Lactation
There are no data regarding the presence of fruquintinib or its metabolites in human milk or its effects on a breastfed child or on milk production. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment with fruquintinib and for 2 weeks after the last dose.
Females and Males of Reproductive Potential
Verify pregnancy status of females of reproductive potential prior to initiating fruquintinib.
Females of childbearing potential and males with female partners of childbearing potential should use effective contraception during treatment and for 2 weeks after the last dose of fruquintinib.
Pediatric Use
The safety and efficacy of fruquintinib in patients younger than 18 years of age have not been established.
Geriatric Use
In the FRESCO-2 study, 212 (46%) patients who received fruquintinib were ≥65 years of age and older, of whom 43 (20%) of patients were ≥75 years of age. There were no observed overall differences in safety and effectiveness of fruquintinib in geriatric compared to younger patients.
Of the total number of fruquintinib-treated patients in the FRESCO study, 50 (18%) were 65 years of age and older, and one patient was ≥75 years of age. There were no observed overall differences in safety and effectiveness of fruquintinib in geriatric compared to younger patients.
Hepatic Impairment
No dosage adjustment is recommended for patients with mild hepatic impairment (total bilirubin less than or equal to the ULN with AST greater than ULN or total bilirubin greater than 1 to 1.5 times ULN with any AST).
Fruquintinib has not been sufficiently studied in patients with moderate hepatic impairment (total bilirubin greater than 1.5 times and less than 3 times ULN and any AST). Fruquintinib is not recommended for use in patients with severe hepatic impairment (total bilirubin greater than 3 times ULN and any AST).
Common Adverse Effects
Most common adverse reactions (incidence ≥20%) are hypertension, palmar-plantar erythrodysesthesia, proteinuria, dysphonia, abdominal pain, diarrhea, and asthenia.
