Pharmacology

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.

Half-Life Elimination

~6 days (range: 4 to 7 days)

Special Populations Note

Body weight: Patients weighing ≥100 kg had a 29% increase in systemic exposure compared with patients weighing 50 to 100 kg.

Use: Labeled Indications

Colorectal cancer, metastatic: Treatment of metastatic colorectal cancer (in combination with fluorouracil, leucovorin, and irinotecan [FOLFIRI]) that is resistant to or has progressed on an oxaliplatin-based regimen.

Off Label Uses

Ascites (symptomatic; due to malignant ovarian cancer)

Data from a multicenter, double-blind, placebo-controlled, parallel group, phase 2 trial in patients with advanced chemoresistant ovarian cancer (including fallopian tube or primary peritoneal adenocarcinoma) and recurrent symptomatic malignant ascites (requiring paracenteses) suggest that ziv-aflibercept may be efficacious in managing refractory ascites and providing symptomatic relief, although vascular endothelial growth factor (VEGF) blockade should be used with caution in this patient population due to the risk of fatal GI perforation (Gotlieb 2012).

Contraindications

There are no contraindications listed in the manufacturer’s labeling.

Dosing: Adult

Ascites, symptomatic; due to malignant ovarian cancer (off-label use; based on limited data): IV: 4 mg/kg every 2 weeks for 2 to 6 months (Gotlieb 2012). Note: Vascular endothelial growth factor (VEGF) blockade should be used with caution in this patient population due to the risk of fatal GI perforation.

Colorectal cancer, metastatic: IV: 4 mg/kg every 2 weeks (in combination with fluorouracil, leucovorin, and irinotecan [FOLFIRI]), continue until disease progression or unacceptable toxicity (Van Cutsem 2012).

ALERT: U.S. Boxed Warning

Hemorrhage:

Severe and sometimes fatal hemorrhage, including GI hemorrhage, has been reported in patients who have received ziv-aflibercept in combination with irinotecan, leucovorin, and 5-fluorouracil (FOLFIRI). Monitor patients for signs and symptoms of GI bleeding and other severe bleeding. Do not administer ziv-aflibercept to patients with severe hemorrhage.

GI perforation:

GI perforation, including fatal GI perforation, can occur in patients receiving ziv-aflibercept. Discontinue ziv-aflibercept therapy in patients who experience GI perforation.

Compromised wound healing:

Severe compromised wound healing can occur in patients receiving ziv-aflibercept with irinotecan, leucovorin, and 5-fluorouracil. Discontinue ziv-aflibercept in patients with compromised wound healing. Suspend ziv-aflibercept for at least 4 weeks prior to elective surgery, and do not resume ziv-aflibercept for at least 4 weeks following major surgery and until the surgical wound is fully healed.

Warnings/Precautions

Concerns related to adverse effects:

• Bone marrow suppression: A higher incidence of neutropenia and complications due to neutropenia (neutropenic fever and infection), including grade 3 and 4 events, occurred with ziv-aflibercept. Leukopenia and thrombocytopenia have also occurred. Monitor CBC with differential (baseline and prior to each cycle); delay treatment until ANC is ≥1,500/mm3.

• Diarrhea: Severe diarrhea and dehydration (grades 3 and 4) have been reported with ziv-aflibercept. 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 ziv-aflibercept in patients who develop fistula.

• Gastrointestinal perforation: [US Boxed Warning]: GI perforation, including fatal GI perforation, may occur in patients receiving ziv-aflibercept. Discontinue ziv-aflibercept therapy in patients who experience GI perforation. Monitor for signs/symptoms of GI perforation.

• Hemorrhage: The risk for hemorrhage is increased with ziv-aflibercept. [US Boxed Warning]: Severe and sometimes fatal hemorrhage, including GI bleeding, has been reported in patients who have received ziv-aflibercept in combination with FOLFIRI. Monitor patients for signs and symptoms of GI bleeding and other severe bleeding. Do not administer ziv-aflibercept to patients with severe hemorrhage. Discontinue if severe hemorrhage develops. Grade 3 and 4 hemorrhagic events, including hematuria and postprocedural hemorrhage, have been reported. Intracranial hemorrhage and pulmonary hemorrhage/hemoptysis (including fatal events) have also occurred.

• Hypertension: The risk for grades 3/4 hypertension is increased with ziv-aflibercept. Onset is generally within the first 2 treatment cycles. Monitor blood pressure every 2 weeks (more frequently if clinically indicated). Manage with appropriate antihypertensive therapy (may require adjustment of existing antihypertensives). Temporarily withhold ziv-aflibercept treatment with uncontrolled hypertension; may reinitiate with permanent dose reduction when controlled. Discontinue for hypertensive crisis or hypertensive encephalopathy. Patients with NYHA class III or IV heart failure were excluded from clinical trials.

• Proteinuria/nephrotic syndrome: Severe 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: Cases of reversible posterior leukoencephalopathy syndrome 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 accident, and angina, have occurred. Discontinue ziv-aflibercept in patients who experience ATEs.

• Wound healing impairment: [US Boxed Warning]: Severely compromised wound healing may occur in patients receiving ziv-aflibercept with FOLFIRI. Discontinue ziv-aflibercept in patients with compromised wound healing. Suspend ziv-aflibercept for at least 4 weeks prior to elective surgery, and do not resume ziv-aflibercept for 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, tooth extraction), ziv-aflibercept may be resumed or initiated as soon as the surgical wound is fully healed.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Elderly: Certain adverse events, such as diarrhea, dizziness, weakness, weight loss, and dehydration, occurred at a higher incidence in elderly patients compared to younger adults; monitor closely during treatment.

Monitoring Parameters

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

C

Pregnancy Considerations

Based on the mechanism of action and data from animal reproduction studies, in utero exposure to ziv-aflibercept may cause fetal harm. Aflibercept is a vascular endothelial growth factor (VEGF) inhibitor; VEGF is required to achieve and maintain normal pregnancies (Peracha 2016).

Males and females of reproductive potential should use effective contraception during therapy and for at least 3 months following ziv-aflibercept treatment.

Patient Education

• 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 weight loss, diarrhea, lack of appetite, loss of strength and energy, mouth sores, mouth irritation, 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; hematuria; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any severe or persistent bleeding), signs of posterior reversible encephalopathy syndrome (confusion, not alert, vision changes, seizures, or severe headache), signs of fluid and electrolyte problems (mood changes, confusion, muscle pain or weakness, abnormal heartbeat, severe dizziness, passing out, tachycardia, increased thirst, seizures, loss of strength and energy, lack of appetite, urinary retention or change in amount of urine passed, dry mouth, dry eyes, or nausea or vomiting), signs of severe cerebrovascular disease (change in strength on one side is greater than the other, difficulty speaking or thinking, change in balance, or vision changes), signs of DVT (edema, warmth, numbness, change in color, or pain in the extremities), severe headache, severe dizziness, passing out, wound healing impairment, chest pain, shortness of breath, vision changes, severe abdominal pain, 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.
