About ZALTRAP® (ziv-aflibercept) Injection for Intravenous Infusion
ZALTRAP is indicated for use in combination with 5-fluorouracil, leucovorin, irinotecan (FOLFIRI) for patients with metastatic colorectal cancer (mCRC) that is resistant to or has progressed following an oxaliplatin-containing regimen. ZALTRAP was approved by the U.S. Food and Drug Administration on August 3, 2012. ZALTRAP received a CHMP positive opinion for marketing authorization in the European Union in November 2012, and marketing authorization applications for ZALTRAP are under review by the European Medicines Agency and other regulatory agencies worldwide.
ZALTRAP is a recombinant fusion protein, which acts as a soluble receptor that binds to Vascular Endothelial Growth Factor-A (VEGF-A), VEGF-B and placental growth factor (PIGF). Inhibition of these factors can result in decreased neovascularization and decreased vascular permeability. ZALTRAP is formulated as a hyperosomotic solution and must be diluted prior to intravenous administration. ZALTRAP is intended for intravenous infusion only and is not to be administered by other routes.
ZALTRAP was discovered by Regeneron Pharmaceuticals and co-developed with Sanofi. Sanofi and Regeneron co-commercialize ZALTRAP in the United States. In the US, ZALTRAP is a registered trademark of Regeneron Pharmaceuticals, Inc.
Important Safety Information for ZALTRAP®
WARNING: HEMORRHAGE, GASTROINTESTINAL PERFORATION, COMPROMISED
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.
- For minor surgery such as central venous access port placement, biopsy, and tooth extraction, ZALTRAP may be initiated/resumed once the surgical wound is fully healed.
- Fistula formation involving GI and non-GI sites occurs at a higher incidence in patients treated with ZALTRAP. Fistulas (anal, enterovesical, enterocutaneous, colovaginal, intestinal sites) were reported in 1.5% (9/611) of ZALTRAP/FOLFIRI treated patients and 0.5% (3/605) of placebo/FOLFIRI patients. Grade 3 GI fistula formation occurred in 2 patients treated with Zaltrap (0.3%) and 1 placebo-treated patient (0.2%). Discontinue ZALTRAP therapy in patients who develop fistula.
- An increased risk of Grade 3-4 hypertension has been observed in patients receiving ZALTRAP.
- There is no clinical trial experience administering ZALTRAP to patients with NYHA class III or IV heart failure. In patients with mCRC, Grade 3 hypertension (defined as requiring adjustment in existing anti-hypertensive therapy or treatment with more than one drug) was reported in 1.5% of patients treated with placebo/FOLFIRI and 19% treated with ZALTRAP/FOLFIRI. Grade 4 hypertension (hypertensive crisis) was reported in 1 patient (0.2%) treated with ZALTRAP/FOLFIRI. Of patients treated with ZALTRAP/FOLFIRI who developed Grade 3-4 hypertension, 54% had onset during the first two cycles of treatment.
- Monitor blood pressure at least every two weeks, treat with appropriate anti-hypertensive therapy, and continue monitoring blood pressure regularly during ZALTRAP treatment. Temporarily suspend ZALTRAP until hypertension is controlled, and reduce ZALTRAP dose to 2 mg/kg for subsequent cycles. Discontinue Zaltrap in patients with hypertensive crisis or hypertensive encephalopathy.
- Arterial thromboembolic events (ATE), including transient ischemic attack, cerebrovascular accident, and angina pectoris, occurred more frequently in patients who have received ZALTRAP. ATE occurred in 2.6% of ZALTRAP/FOLFIRI patients and 1.7% of placebo/FOLFIRI patients. Grade 3-4 events occurred in 11 patients (1.8%) treated with ZALTRAP/FOLFIRI and 4 patients (0.7%) treated with placebo/FOLFIRI. Discontinue ZALTRAP in patients who experience an ATE.
- Severe proteinuria, nephrotic syndrome, and thrombotic microangiopathy (TMA) occurred more frequently in patients treated with ZALTRAP.
- 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 urinary protein creatinine ratio (UPCR) for the development or worsening of proteinuria. Obtain a 24-hour urine collection in patients with a 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.
- Incidence of severe diarrhea and dehydration is increased in patients treated with ZALTRAP/FOLFIRI.
- Grade 3-4 diarrhea was reported in 19% of ZALTRAP/FOLFIRI patients compared to 8% of placebo/FOLFIRI patients. Grade 3-4 dehydration was reported in 4% of ZALTRAP/FOLFIRI patients compared to 1% of placebo/FOLFIRI patients.
- The incidence of diarrhea is increased in patients ≥65 years of age compared to patients ˂65 years of age. Monitor closely.
- RPLS (also known as posterior reversible encephalopathy syndrome) was reported in 0.5% of 3795 patients treated with ZALTRAP monotherapy or in combination with chemotherapy. Confirm diagnosis of RPLS with MRI and discontinue ZALTRAP in patients who develop RPLS. Symptoms usually resolve or improve within days, although some patients have experienced ongoing neurologic sequelae or death.
- The most common adverse reactions (all grades, ≥20% incidence) reported at a higher incidence (2% or greater between-arm difference) in the ZALTRAP/FOLFIRI arm, in order of decreasing frequency, were leukopenia, diarrhea, neutropenia, proteinuria, AST increased, stomatitis, fatigue, thrombocytopenia, ALT increased, hypertension, weight decreased, decreased appetite, epistaxis, abdominal pain, dysphonia, serum creatinine increased, and headache.
- The most common Grade 3-4 adverse reactions (≥5%) reported at a higher incidence (2% or greater between-arm difference) in the ZALTRAP/FOLFIRI arm, in order of decreasing frequency, were neutropenia, diarrhea, hypertension, leukopenia, stomatitis, fatigue, proteinuria, and asthenia.
- Infections occurred at a higher frequency in patients receiving ZALTRAP/FOLFIRI (46%, all grades; 12%, Grade 3-4) than in patients receiving placebo/FOLFIRI (33%, all grades; 7%, Grade 3-4), including urinary tract infection, nasopharyngitis, upper respiratory tract infection, pneumonia, catheter site infection, and tooth infection.
- In patients with mCRC, venous thromboembolic events (VTE), consisting primarily of deep venous thrombosis and pulmonary embolism, occurred in 9% of patients treated with ZALTRAP/FOLFIRI and 7% of patients treated with placebo/FOLFIRI.
PREGNANCY AND NURSING MOTHERS
- ZALTRAP should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. 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.
- It is not known whether ZALTRAP is excreted in human milk. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

About Colorectal Cancer
According to the American Cancer Society, more than 143,000 new cases of colorectal cancer were diagnosed in 2012, and more than 51,000 people died from it. Approximately 60 percent of colorectal cancer cases are diagnosed at the locally advanced or metastatic stage. Although survival for early stage disease is relatively high, once colorectal cancer metastasizes to distant organs, five-year survival is estimated to be 12 percent.3
Worldwide, colorectal cancer is the third most commonly diagnosed cancer in males and the second most in females, with more than 1.2 million new cases diagnosed in 2008. One of the deadliest cancers, colorectal cancer was responsible for more than 600,000 deaths globally in 2008 alone.4
