ZALTRAP(R) (ziv-aflibercept) Approved in the EU for Patients with Previously Treated Metastatic Colorectal CancerFirst and only agent to statistically significantly improve survival in combination with FOLFIRI chemotherapy after an oxaliplatin regimen
PARIS and TARRYTOWN, N.Y., Feb. 5, 2013 -- (Healthcare Sales & Marketing Network) -- Sanofi (EURONEXT: SAN and NYSE: SNY) and Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the European Commission (EC) has granted marketing authorization in the European Union for ZALTRAP 25mg/ml concentrate for solution for infusion in combination with irinotecan/5-fluorouracil/folinic acid (FOLFIRI) chemotherapy in adults with metastatic colorectal cancer (mCRC) that is resistant to or has progressed after an oxaliplatin-containing regimen. This decision was based on the efficacy and safety results of the VELOUR Phase 3 trial.
"ZALTRAP is an important addition to the metastatic colorectal cancer treatment landscape and helps to fill a critical treatment gap," said Eric Van Cutsem, M.D., Ph.D., University Hospitals Leuven, Belgium and lead investigator of the VELOUR study. "ZALTRAP is the first and only agent to demonstrate a survival improvement in a Phase 3 trial in patients previously treated with an oxaliplatin-based regimen who are being treated with FOLFIRI for their metastatic disease."
"I would like to thank the physicians, patients, and their families for their support in moving ZALTRAP through the clinical trial process leading to approval in Europe," said Debasish Roychowdhury, M.D., Senior Vice President and Head, Sanofi Oncology. "We are thrilled to provide a new therapy that further extends the lives of patients with metastatic colorectal cancer and look forward to working with European health authorities to ensure patients have access to ZALTRAP."
In Europe, colorectal cancer is the most common cancer in both men and women and is the second leading cause of cancer death. In 2008, there were 436,000 new cases diagnosed and 212,000 deaths from colorectal cancer.
Commenting on the marketing authorization, George D. Yancopoulos, M.D., Ph.D., Chief Scientific Officer of Regeneron and President of Regeneron Laboratories, added: "The European approval of ZALTRAP provides a new option to address the unmet medical need in this patient population. There continues to be a need to develop new cancer therapies and Regeneron and Sanofi are committed to finding novel investigational treatments and combinations."
ZALTRAP received approval from the U.S. Food and Drug Administration (FDA) in August 2012 after a Priority Review, and marketing authorization applications for ZALTRAP are under review with other regulatory agencies worldwide.
About the VELOUR Phase 3 Study
The ZALTRAP approval was based on data from the pivotal Phase 3 VELOUR trial, a multinational, randomized, double-blind trial comparing FOLFIRI in combination with either ZALTRAP or placebo in the treatment of patients with mCRC. The study randomized 1,226 patients with mCRC who previously had been treated with an oxaliplatin-containing regimen. Twenty-eight percent of patients in the study received prior bevacizumab therapy. The primary endpoint of the trial was overall survival. Secondary endpoints included progression-free survival, overall response rate, and safety.
The VELOUR trial showed that in patients previously treated with an oxaliplatin containing regimen, adding ZALTRAP to FOLFIRI significantly improved median survival from 12.06 months to 13.50 months (HR=0.817 (95% CI 0.714 to 0.935; p=0.0032), an 18 percent relative risk reduction. A significant improvement in progression-free survival from 4.67 months to 6.90 months (HR=0.758 95% CI 0.661 to 0.869; p=0.00007), a 24 percent relative risk reduction, was also observed. The overall response rate in the ZALTRAP plus FOLFIRI arm was 19.8% vs. 11.1% for FOLFIRI alone (p=0.0001).
The most common adverse reactions (all grades, greater than or equal to 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 (greater than or equal to 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.
About ZALTRAP® (ziv-aflibercept)
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), as shown in preclinical studies. VEGF-A is one of the mediators contributing to angiogenesis. VEGF-B and PlGF, related growth factors in the VEGF family, may contribute to tumor angiogenesis as well. In the US, ZALTRAP is a registered trademark of Regeneron Pharmaceuticals, Inc.
In the US, ZALTRAP is approved with the US proper name ziv-aflibercept. The World Health Organization (WHO) recommended international non-proprietary name for ZALTRAP is aflibercept. Marketing authorization applications for ZALTRAP are also under review other regulatory agencies worldwide.

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® (ziv-aflibercept). 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® (ziv-aflibercept) when proteinuria greater than or equal to 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 greater than or equal to 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.

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 experiences ongoing neurologic sequelae or death.
The most common adverse reactions (all grades, greater than or equal to 20% incidence) reported at a higher incidence (2% or greater between-arm difference) in the ZALTRAP® (ziv-aflibercept)/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 (greater than or equal to 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® (ziv-aflibercept)/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
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. According to the American Cancer Society, 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.
