Use of ZALTRAP® (ziv‑aflibercept) in Specific Populations1

Pregnancy
Pregnancy Category C

Risk Summary
There are no adequate and well-controlled studies with ZALTRAP in pregnant women. ZALTRAP was embryotoxic and teratogenic in rabbits at exposure levels lower than human exposures at the recommended dose, with increased incidences of external, visceral, and skeletal fetal malformations. ZALTRAP should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Animal Data
Ziv-aflibercept produced embryo-fetal toxicity when administered every 3 days during organogenesis in pregnant rabbits at all intravenous doses tested, ≥3 mg per kg. Adverse embryo-fetal effects included increased incidences of postimplantation losses and external (including anasarca, umbilical hernia, diaphragmatic hernia and gastroschisis, cleft palate, ectrodactyly, and atresia), visceral (in the heart, great vessels, and arteries), and skeletal fetal malformations (including fused vertebrae, sternebrae, and ribs; supernumerary arches and ribs, and incomplete ossification). Administration of the 3 mg per kg dose to rabbits resulted in systemic exposure (AUC) that was approximately 30% of the AUC in patients at the recommended dose. The incidence and severity of fetal anomalies increased with increasing dose.

Nursing Mothers
It is not known whether ZALTRAP is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from ZALTRAP, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use
The safety and effectiveness in pediatric patients have not been established. In a dose-escalation, safety, and tolerability study, 21 patients ages 2 to 21 years (median age 12.9) with solid tumors received ZALTRAP at doses ranging from 2 to 3 mg/kg, IV, every two weeks. The pharmacokinetics of free ziv-aflibercept were evaluated in 8 of these patients (ages 5 to 17 years) [see Clinical Pharmacology (12.3)]. The maximum tolerated dose in the study was 2.5 mg/kg, below the dose known to be safe and effective in adults with mCRC.

Geriatric Use
Of the 611 patients with mCRC treated with ZALTRAP/FOLFIRI, 205 (34%) were 65 years or older, and 33 (5%) were 75 years or older. Elderly patients (≥65 years of age) experienced higher incidences (≥5%) of diarrhea, dizziness, asthenia, weight decrease, and dehydration when compared to younger patients. Monitor elderly patients more closely for diarrhea and dehydration.

The effect of ZALTRAP on overall survival was similar in patients <65 years old and ≥65 years old who received ZALTRAP/FOLFIRI.

No dose adjustment of ZALTRAP is recommended for patients ≥65 years of age.

Hepatic Impairment
No dedicated clinical studies have been conducted to evaluate the effect of hepatic impairment on the pharmacokinetics of ziv-aflibercept.

Based on a population PK analysis with data from 1507 patients, ziv-aflibercept exposure in patients with mild and moderate hepatic impairment were similar to those in patients with normal hepatic function. There are no data available for patients with severe hepatic impairment.

Renal Impairment
No dedicated clinical studies have been conducted to evaluate the effect of renal impairment on the pharmacokinetics of ziv-aflibercept.

Based on a population PK analysis with data from 1507 patients, ziv-aflibercept exposure in patients with mild, moderate, and severe renal impairment were similar to those in patients with normal renal function.

Females and Males of Reproductive Potential
Male and female reproductive function and fertility may be compromised during treatment with ZALTRAP, as suggested by findings in monkeys. These animal findings were reversible within 18 weeks after cessation of treatment. Females and males of reproductive potential should use highly effective contraception during and up to a minimum of 3 months after the last dose of treatment.

ZALTRAP®, in combination with 5-fluorouracil, leucovorin, irinotecan-(FOLFIRI), is indicated for patients with metastatic colorectal cancer (mCRC) that is resistant to or has progressed following an oxaliplatin-containing regimen.

IMPORTANT SAFETY INFORMATION FOR ZALTRAP® (ZIV–AFLIBERCEPT) INJECTION FOR INTRAVENOUS INFUSION

WARNING: HEMORRHAGE, GASTROINTESTINAL PERFORATION, COMPROMISED WOUND HEALING

Severe and sometimes fatal hemorrhage, including gastrointestinal (GI) hemorrhage, has been reported in the patients who have received ZALTRAP in combination with FOLFIRI. Monitor patients for signs and symptoms of GI bleeding and other severe bleeding. Do not administer ZALTRAP to patients with severe hemorrhage.

GI perforation including fatal GI perforation can occur in patients receiving ZALTRAP. Discontinue ZALTRAP therapy in patients who experience GI perforation.

Severe compromised wound healing can occur in patients receiving ZALTRAP/FOLFIRI. Discontinue ZALTRAP in patients with compromised wound healing. Suspend ZALTRAP for at least 4 weeks prior to elective surgery, and do not resume ZALTRAP for at least 4 weeks following major surgery and until the surgical wound is fully healed.

warnings and precautions

  • Patients treated with ZALTRAP have an increased risk of hemorrhage, including severe and sometimes fatal hemorrhagic events.
    • Bleeding/hemorrhage (all grades) occurred in 38% of ZALTRAP/FOLFIRI patients vs. 19% of placebo/FOLFIRI patients. Grade 3–4 hemorrhagic events, including GI hemorrhage, hematuria, and post–procedural hemorrhage, occurred in 3% of ZALTRAP/FOLFIRI patients vs. 1% of placebo/FOLFIRI patients. Severe intracranial hemorrhage and pulmonary hemorrhage/hemoptysis including fatal events have occurred in patients receiving ZALTRAP.
    • Monitor patients for signs and symptoms of bleeding. Do not initiate ZALTRAP in patients with severe hemorrhage. Discontinue ZALTRAP in patients who develop severe hemorrhage.
  • GI perforation including fatal GI perforation can occur in patients receiving ZALTRAP.
    • Across three clinical trials (colorectal, pancreatic, and lung cancer), GI perforation (all grades/Grade 3–4) occurred in 0.8% /0.8% of Zaltrap patients and 0.3% /0.2% for placebo patients.
    • Monitor patients for signs and symptoms of GI perforation. Discontinue ZALTRAP in patients who experience GI perforation.
  • ZALTRAP impairs wound healing in animal models. Grade 3 compromised wound healing occurred in 2 patients (0.3%) treated with ZALTRAP/FOLFIRI and none of the patients treated with placebo/FOLFIRI.
    • Discontinue ZALTRAP in patients with compromised wound healing.
    • Suspend ZALTRAP for at least 4 weeks prior to elective surgery and do not initiate/resume ZALTRAP until at least 4 weeks after major surgery and surgical wound is fully healed.

    • Proteinuria was reported in 62% of ZALTRAP/FOLFIRI patients compared to 41% of placebo/FOLFIRI patients. Grade 3–4 proteinuria occurred in 8% of ZALTRAP/FOLFIRI patients compared to 1% of placebo/FOLFIRI patients. Nephrotic syndrome occurred in 2 patients (0.5%) treated with ZALTRAP/FOLFIRI compared to none of the patients treated with placebo/FOLFIRI. TMA was reported in 3 of 2258 patients with cancer enrolled across completed studies.
    • Monitor proteinuria by urine dipstick analysis and/or urinary protein creatinine ratio (UPCR) for the development or worsening of proteinuria. Obtain a 24-hour urine collection in patients with a dipstick of ≥2+ for protein or UPCR ˃1.
    • Suspend ZALTRAP when proteinuria ≥2 grams/24 hours and resume ZALTRAP when proteinuria <2 grams/24 hours.
    • If recurrent, suspend until proteinuria <2 grams/24hours and then reduce ZALTRAP dose to 2 mg/kg.
    • Discontinue ZALTRAP if nephrotic syndrome or TMA develops.
  • A higher incidence of neutropenic complications (febrile neutropenia and neutropenic infection) occurred in patients receiving ZALTRAP.
    • Grade 3–4 neutropenia occurred in 37% of ZALTRAP/FOLFIRI patients compared to 30% of placebo/FOLFIRI patients. Grade 3–4 febrile neutropenia occurred in 4% of ZALTRAP/FOLFIRI patients compared to 2% of placebo/FOLFIRI patients. Grade 3–4 neutropenic infection/sepsis occurred in 1.5% of ZALTRAP/FOLFIRI patients compared to 1.2% of placebo/FOLFIRI patients.
    • Monitor CBC with differential count at baseline and prior to initiation of each cycle of ZALTRAP. Delay administration of ZALTRAP/FOLFIRI until neutrophil count is ≥1.5 x 109/L.
