Also known as VEGF-trap, ziv-aflibercept is a recombinant fusion protein which is comprised of portions of binding domains for vascular endothelial growth factor (VEGF) receptors 1 and 2, attached to the Fc portion of human IgG1. Ziv-aflibercept acts as a decoy receptor for VEGF-A, VEGF-B, and placental growth factor (PlGF) which prevent VEGF receptor binding/activation to their receptors (an action critical to angiogenesis), thus leading to antiangiogenesis and tumor regression.

Concerns related to adverse effects:
• Bone marrow suppression: A higher incidence of neutropenia and complications due to neutropenia (neutropenic fever and infection) occurred in patients receiving ziv-aflibercept. Leukopenia and thrombocytopenia were also observed in clinical trials. Monitor CBC with differential (baseline and prior to each cycle); delay treatment until ANC is ≥1,500/mm3.
• Diarrhea: Severe diarrhea and dehydration have been reported. The incidence of diarrhea is increased in patients ≥65 years of age; monitor elderly patients closely for diarrhea.
• Fistula formation: The risk for gastrointestinal (GI) and non-GI fistulas is increased with ziv-aflibercept. Fistula sites have included anal, enterovesical, enterocutaneous, colovaginal, and intestinal. Discontinue in patients who develop fistula.
• Gastrointestinal perforation: [U.S. Boxed Warning]: Severe or fatal GI perforation is a possibility; discontinue ziv-aflibercept if GI perforation occurs. Monitor for signs/symptoms of GI perforation.
• Hemorrhage: The risk for hemorrhage is increased with ziv-aflibercept. [U.S. Boxed Warning]: Severe and occasionally fatal hemorrhage, including GI bleeding, has been reported with ziv-aflibercept/FOLFIRI. Monitor for signs and symptoms of GI and other severe bleeding events. Do not administer to patients with severe hemorrhage. Discontinue if severe hemorrhage develops. Hemorrhagic events have also included hematuria, postprocedural hemorrhage, intracranial hemorrhage, and pulmonary hemorrhage/hemoptysis.
• Hypertension: The risk for grades 3/4 hypertension is increased. Onset is generally within the first 2 treatment cycles. Monitor blood pressure every 2 weeks (more frequently if clinically indicated). Treat with appropriate antihypertensive therapy (may require adjustment of existing antihypertensives). Temporarily withhold treatment with uncontrolled hypertension; may reinitiate with permanent dose reduction when controlled. Discontinue for hypertensive crisis or encephalopathy. Patients with NYHA class III or IV heart failure were excluded from clinical trials.
• Proteinuria/nephrotic syndrome: Proteinuria, nephrotic syndrome, and thrombotic microangiopathy (TMA) have been associated with ziv-aflibercept. Evaluate for proteinuria during treatment with urine dipstick and/or urinary protein creatinine ratio (UPCR); if dipstick ≥2+ for protein or UPCR >1, obtain 24-hour urine collection. Withhold ziv-aflibercept for proteinuria ≥2 g per 24 hours; for recurrent proteinuria, withhold treatment until <2 g per 24 hours and then resume with permanent dose reduction. Discontinue treatment for nephrotic syndrome or TMA.
• Reversible posterior leukoencephalopathy syndrome (RPLS): Cases of RPLS have been reported. Confirm diagnosis with MRI; discontinue ziv-aflibercept if verified. Symptoms generally resolve or improve within days, although persistent neurologic symptoms and death have been reported.
• Thromboembolism: Arterial thrombotic events (ATE), including transient ischemic attack, cerebrovascular accidents, and angina have occurred. Discontinue ziv-aflibercept in patients who experience ATEs.
• Wound healing impairment: [U.S. Boxed Warning]: Severely compromised wound healing may occur with ziv-aflibercept/FOLFIRI. Discontinue ziv-aflibercept with compromised wound healing. Withhold ziv-aflibercept at least 4 weeks prior to elective surgery. Do not resume ziv-aflibercept treatment until at least 4 weeks after major surgery AND until the surgical wound is completely healed. For minor surgeries (eg, central venous access port placement, biopsy, or tooth extraction), ziv-aflibercept may be resumed or initiated as soon as the surgical wound is fully healed.
• Elderly: Certain adverse events, such as diarrhea, dizziness, weakness, weight loss, and dehydration, occurred at a higher incidence in elderly compared to younger adults; monitor closely during treatment.
CBC with differential (baseline and prior to each cycle); urine protein (dipstick analysis and/or urinary protein creatinine ratio [UPCR], obtain 24-hour urine collection if dipstick ≥2+ for protein or UPCR >1); blood pressure (every 2 weeks; more frequently if clinically indicated); monitor for signs/symptoms of hemorrhage or GI perforation; monitor elderly patients closely for diarrhea and/or dehydration. Monitor wounds for healing impairment.
Pregnancy Risk Factor
Adverse events were observed in animal reproduction studies with doses providing systemic exposure equivalent to ~30% of a human dose. The incidence of fetal malformations increased with increasing doses. Patients (male and female) should use effective contraception during therapy and for at least 3 months following treatment.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache, abdominal pain, weight loss, diarrhea, lack of appetite, loss of strength and energy, mouth sores, rhinorrhea, change in voice, or skin discoloration. Have patient report immediately to prescriber signs of infection, signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; blood in the urine; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any bleeding that is very bad or that will not stop), signs of posterior reversible encephalopathy syndrome (illogical thinking, not alert, vision changes, seizures, or severe headache), signs of fluid and electrolyte problems (mood changes, confusion, muscle pain or weakness, abnormal heartbeat, very bad dizziness or passing out, fast heartbeat, more thirst, seizures, feeling very tired or weak, not hungry, unable to pass urine or change in the amount of urine produced, dry mouth, dry eyes, or nausea or vomiting), signs of severe cerebrovascular disease (change in strength on one side is greater than the other, trouble speaking or thinking, change in balance, or change in eyesight), signs of DVT (edema, warmth, numbness, change in color, or pain in the extremities), severe dizziness, passing out, burning or numbness feeling, wound healing impairment, angina, shortness of breath, vision changes, blindness, or redness or irritation of palms or soles of feet (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
