About ZALTRAP® (aflibercept) and the Clinical Development Program

ZALTRAP, also known as aflibercept, is an investigational angiogenesis inhibitor with a unique mechanism of action.  This fusion protein binds all forms of Vascular Endothelial Growth Factor-A (VEGF-A), as well as VEGF-B and placental growth factor (PIGF), additional angiogenic growth factors that appear to play a role in tumor angiogenesis and inflammation. ZALTRAP has been shown to bind VEGF-A, VEGF-B, and PlGF with higher affinity than their native receptors.

Sanofi Oncology and Regeneron are collaborating on a broad oncology development program for ZALTRAP.  The Phase 3 clinical program was designed to evaluate ZALTRAP in combination with common chemotherapy regimens in the treatment of patients with advanced cancers, including cancers where bevacizumab has not demonstrated efficacy.  Patients who had previously received bevacizumab were also included in the clinical trials for certain second-line treatment settings.  The current development program is focused on metastatic prostate and colorectal cancers and includes the following late stage trials:

• VENICE: First-line treatment for androgen-independent (hormone-refractory) metastatic prostate cancer in combination with docetaxel and prednisone (Phase 3).  Final results are anticipated in 2012.

• AFFIRM: First-line treatment in metastatic colorectal cancer in combination with a modified FOLFOX6 regimen (Phase 2).  Final results are expected during the second half of 2011.

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.  Colorectal cancer is one of the deadliest cancers and was responsible for more than 600,000 deaths in 2008 alone.  In Europe the overall survival rate is 43 percent, whereas in the United States it is 62 percent; these numbers drop considerably when the cancer spreads to distant organs.  The risk of colorectal cancer increases with age — in developed countries, more than 90 percent of cases are diagnosed in individuals older than age 50.
