Severe bleeding has occurred with ziv-aflibercept use, including GI bleeding, intracranial bleeding, and pulmonary hemorrhage/hemoptysis; some cases were fatal. Monitor patients for signs and symptoms of bleeding. Do not use ziv-aflibercept in patients with severe hemorrhage and discontinue therapy if patients develop severe bleeding.
GI perforation has been reported with ziv-aflibercept use; some cases were fatal. Monitor patients for signs and symptoms of GI perforation; discontinue therapy if patients develop GI perforation.
Compromised wound healing/wound dehiscence has been reported in patients who received ziv-aflibercept. Temporary suspension of therapy is recommended at least 4 weeks before elective surgery. After major surgery, do not restart ziv-aflibercept for at least 4 weeks and until the surgical wound is entirely healed. Ziv-aflibercept may be initiated/resumed once the surgical wound is entirely healed after minor surgery (e.g., central venous access port placement, biopsy, dental work such as tooth extraction). Discontinue therapy if patients develop impaired wound healing.

ZALTRAP Intravenous Inj Sol: 1mL, 25mg
4 mg/kg IV over 1 hour, followed by FOLFIRI (irinotecan 180 mg/m2 IV over 90 minutes and leucovorin 400 mg/m2 IV over 2 hours (infused at the same time via Y-line), followed by 5-FU 400 mg/m2 IV bolus then 2,400 mg/m2 as a 46-hour continuous IV infusion) on day 1, every 2 weeks until disease progression or unacceptable toxicity. Administer ziv-aflibercept prior to FOLFIRI. In a randomized, double-blind, placebo-controlled, phase III study (the VELOUR study), treatment cycles were repeated every 2 weeks until disease progression or unacceptable toxicity. The median overall survival (OS) time (primary endpoint) was significantly improved with ziv-aflibercept plus FOLFIRI compared with FOLFIRI alone (13.5 vs. 12.06 months; hazard ratio (HR) = 0.817; 95% CI, 0.713 to 0.937; p = 0.0032) in 1,226 metastatic colorectal cancer patients who were resistant to or had progressed during or within 6 months of an oxaliplatin-containing regimen. Additionally, the progression-free survival (PFS) time was significantly improved with ziv-aflibercept plus FOLFIRI compared with FOLFIRI alone (6.9 vs. 4.67 months; HR = 0.758; 95% CI, 0.661 to 0.869; p < 0.0001). In a preplanned subgroup analysis, OS was not improved in the 373 patients who had previously received bevacizumab in combination with oxaliplatin-containing therapy (HR = 0.862; 95% CI, 0.673 to 1.104).
4 mg/kg IV q2 weeks.
Safety and efficacy have not been established.
Specific guidelines for dosage adjustments in hepatic impairment are not available. Ziv-aflibercept has not been studied in patients with severe hepatic impairment (total bilirubin greater than 3 times the upper limit of normal and any AST/ALT).
Specific guidelines for dosage adjustments in renal impairment are not available; it appears that no dosage adjustments are needed.

Reversible posterior leukoencephalopathy syndrome (RPLS), also known as posterior reversible encephalopathy syndrome (PRES), has been reported in patients treated with ziv-aflibercept. Discontinue ziv-aflibercept in patients suspected of developing RPLS. Patients with headache, lethargy, seizures, confusion, blindness, and other visual or neurologic disturbances should be evaluated for RPLS with magnetic resonance imaging (MRI). Mild to severe hypertension may also be present. Symptoms usually resolve or improve within days of treatment discontinuation; however, some patients have experienced ongoing neurologic sequelae.
Severe hypertension, including hypertensive crisis, has been reported with ziv-aflibercept use. Monitor blood pressure every 2 weeks or more often if clinically indicated; treat hypertension with antihypertensive therapy. In patients with recurrent or severe hypertension, temporarily hold therapy until blood pressure is controlled and then permanently reduce the ziv-aflibercept dose. Discontinue therapy in patients who develop hypertensive crisis or hypertensive encephalopathy. Over half of the grade 3 or 4 hypertension cases occurred within the first 2 cycles of ziv-aflibercept therapy. Use ziv-aflibercept with caution in patients with pre-existing hypertension.
Severe proteinuria, including nephrotic syndrome or thrombotic microangiopathy (TMA), has been reported with ziv-aflibercept use. Monitor urine protein by urine dipstick analysis and urinary protein creatinine ratio (UPCR); obtain a 24-hour urine collection for a UPCR higher than 1 or a urine dipstick of 2+ or higher for protein. For proteinuria of 2 grams/24 hours, temporarily hold therapy until proteinuria is less than 2 grams/24 hours. If proteinuria recurs, hold therapy until proteinuria is less than 2 grams/24 hours then permanently reduce the ziv-aflibercept dose. Discontinue therapy in patients who develop nephrotic syndrome or TMA.
Neutropenic complications, including febrile neutropenia and neutropenic infection/sepsis, has been reported with ziv-aflibercept use. Monitor complete blood counts with differential at baseline and prior to each cycle of therapy; hold ziv-aflibercept/FOLFIRI therapy until the neutrophil count is greater than or equal to 1.5 X 109/L.
There was a higher incidence of toxicity (>= 5%) including diarrhea, dizziness, asthenia, weight loss, and dehydration with ziv-aflibercept plus 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI) therapy in geriatric patients (>= 65 years of age) with metastatic colorectal cancer compared with younger patients in a randomized study. Although no dosage adjustment is necessary in elderly patients, careful monitoring for diarrhea and dehydration is recommended in this population.
Counsel patients about the reproductive risk and contraception requirements during ziv-aflibercept treatment. Ziv-aflibercept can be teratogenic if taken by the mother during pregnancy; male-mediated teratogenicity is also possible. Females of reproductive potential should avoid pregnancy and undergo pregnancy testing prior to initiation of treatment with ziv-aflibercept. Females and males should use highly effective contraception during and for at least 3 months after treatment. Women who become pregnant while receiving ziv-aflibercept should be apprised of the potential hazard to the fetus. In addition, based on animal data, ziv-aflibercept may cause impaired fertility or infertility. Specifically, ziv-aflibercept inhibited ovarian function and follicular development in monkeys, and caused alterations in sperm morphology and decreased sperm motility. These effects were observed at all doses tested including the lowest tested dose, which was approximately 60% of the AUC in humans at the recommended dose. Reversibility was observed within 18 weeks after cessation of treatment.
Ziv-aflibercept is classified as FDA pregnancy category C. No adequate studies of ziv-aflibercept exist in pregnant women. Ziv-aflibercept was embryotoxic and teratogenic in rabbits at exposure levels that were less than recommended human exposure levels. In rabbits, doses of 3 mg/kg IV resulted in an AUC that was 30% of the human exposure; increasing doses resulted in more frequent and severe fetal abnormalities. Adverse embryo-fetal effects included increased incidences of post-implantation losses and external (e.g., anasarca, umbilical hernia, diaphragmatic hernia and gastroschisis, cleft palate, ectrodactyly, and atresia), visceral (e.g., heart, great vessels, and arteries), and skeletal (e.g., incomplete ossification, supernumerary arches and ribs, and fused vertebrae, sternebrae, and ribs) fetal malformations. Use ziv-aflibercept during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus.
According to the manufacturer, ziv-aflibercept or breast-feeding should be discontinued because of the potential for serious adverse reactions in nursing infants from ziv-aflibercept. It is not known if ziv-aflibercept is excreted into human milk. Consider the benefits of breast-feeding, the risk of infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.

Clozapine: (Major) It is unclear if concurrent use of other drugs known to cause neutropenia (e.g., antineoplastic agents) increases the risk or severity of clozapine-induced neutropenia. Because there is no strong rationale for avoiding clozapine in patients treated with these drugs, consider increased absolute neutrophil count (ANC) monitoring and consult the treating oncologist.
Ziv-aflibercept is an angiogenesis inhibitor. It is a fully humanized recombinant fusion protein that acts as a soluble receptor to bind vascular endothelial growth factor (VEGF)-A, VEGF-B, and placental growth factors 1 and 2, which prevents other native receptors from binding. Inhibition of native receptor binding can result in decreased neovascularization and decreased vascular permeability. In animals, ziv-aflibercept inhibited the growth of new blood vessels through inhibition of endothelial cell proliferation. Also, in mice, ziv-aflibercept inhibited the growth of xenotransplanted colon tumors.
Ziv-Aflibercept is administered by intravenous infusion. The elimination half-life of free ziv-aflibercept was approximately 6 days (range, 4 to 7 days) after 4 mg/kg IV every two weeks. Free ziv-aflibercept concentrations appear to exhibit linear pharmacokinetic parameters in the dose range of 2 to 9 mg/kg.
Steady state concentrations of free ziv-aflibercept were reached by the second dose of 4 mg/kg IV every two weeks. The accumulation ratio for free ziv-aflibercept was approximately 1.2.
