Progress on Jevtana®, Zaltrap™ and JAK2 inhibitor featured…


Sanofi (EURONEXT: SAN and NYSE: SNY) announced today abstracts spanning the company’s innovative marketed and late-stage development compounds will be featured at the 2012 American Society of Clinical Oncology Annual Meeting in Chicago, Ill., June 1-5. Sanofi products are noted in more than 170 abstracts to be presented at the meeting.

This year’s meeting theme – Collaborating to Conquer Cancer – aligns with Sanofi Oncology’s approach to drug discovery and development through external partnerships that complement internal expertise. Diverse collaborations with leading scientists, academic institutions and other industry partners have brought forth numerous compounds to be highlighted in poster and oral presentations at the meeting, including investigational agents Zaltrap™ (aflibercept) and the JAK2 inhibitor, SAR302503.

“The data to be presented at ASCO underscore the commitment of Sanofi Oncology to the patient and focus on innovative scientific discovery to develop cancer therapies that meet patient needs,” said Debasish Roychowdhury, M.D., Senior Vice President and Head, Sanofi Oncology. “I thank the investigators and our partners for their strong collaboration in helping realize this progress.”

Zaltrap™ (aflibercept)

Zaltrap™ is a novel investigational recombinant human fusion protein that binds VEGF-A, VEGF-B and PlGF. A Biologics License Application (BLA) for Zaltrap for use in combination with irinotecanfluoropyrimidine- based chemotherapy in patients with metastatic colorectal cancer (mCRC) previously treated with an oxaliplatin-containing regimen is under review at the U.S. Food and Drug Administration (FDA).

About Zaltrap™ (aflibercept) and the Clinical Development Program

Zaltrap™ (aflibercept), also known in the scientific literature as VEGF Trap, 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 is being jointly developed under a global collaboration agreement between Sanofi Oncology and Regeneron Pharmaceuticals, Inc.

About Jevtana® (cabazitaxel)

Jevtana® (cabazitaxel) is a taxane chemotherapy approved in combination with prednisone for the treatment of patients with metastatic hormone-refractory prostate cancer previously treated with a docetaxel-containing treatment regimen.

About SAR302503 (JAK2 Inhibitor)

JAK2 is a key enzyme for blood cell development. SAR302503 is a novel, investigational, selective JAK2 inhibitor that has shown activity in preclinical studies against two activating mutations (JAK2V617F and MPLW515L) of JAK2. Dysregulated JAK2 signaling is thought to be a cause of MF and related disorders. SAR302503 is being investigated in multiple hematologic and solid tumor types.

About ombrabulin

Ombrabulin is an investigational small-molecule vascular-disrupting agent currently in Phase III clinical trials in patients with advanced soft tissue sarcoma, a disease with high unmet medical need, who have not responded to prior treatments and in phase II trials in NSCLC & ovarian cancer. In 2011, ombrabulin was granted orphan drug status for soft tissue sarcoma by the FDA because it is intended to treat a disease in a small patient population.
