PARIS, France I January 8, 2013 I Sanofi (EURONEXT: SAN and NYSE: SNY) today will providean update on its Research & Development (R&D) pipeline with Dr. Elias Zerhouni, President, Global Research and Development, presenting at the JP Morgan Healthcare Conference in San Francisco, California.

Highlights of the presentation will include key products in late stage development in several disease areas with significant development and regulatory milestones in the next six months. Executing a successful strategy to reposition Sanofi R&D has fueled a pipeline with 65 NME (New Molecular Entity) projects and vaccine candidates in clinical development of which 17 are in Phase III or have been submitted to the health authorities for approval.

“Sanofi has made significant progress in the transformation of its R&D over the last couple of years, including advances in late stage projects and early stage pipeline as well as talent recruitment. We feel we have the ingredients to ensure R&D contributes to Sanofi’s goal of sustainable growth in the coming years while rigorously managing R&D costs,” said Dr. Elias Zerhouni.

Regarding regulatory milestones, Sanofi received two positive opinions from the Committee for Medicinal Products for Human Use (CHMP) since the last R&D update on October 25, 2012, with decisions from the European Commission targeted in Q1 2013: Lyxumia® (lixisenatide) in type 2 diabetes and Zaltrap® (aflibercept) in metastatic second-line colorectal cancer.

Portfolio update

·         SAR236553 (collaboration with Regeneron), a subcutaneously administered, fully-humanantibody, is being evaluated for its impact on lowering low-density lipoprotein cholesterol (LDL-C) by targeting PCSK9. In November, Sanofi and Regeneron announced that the ODYSSEY OUTCOMES trial, a Phase III cardiovascular outcomes trial with SAR236553 started to recruit patients. This study will enroll approximately 18,000 patients, who recently suffered an acute coronary syndrome. With the start of this study, eleven Phase III trials are now recruiting hypercholesterolemic patients not at goal for LDL-C and mainly at high cardiovascular risk, a population estimated at 21 million people globally.

·         Clostridium Difficile Toxoid Vaccine, for the prevention of primary symptomaticClostridiumDifficile infections (CDI), is expected to enter Phase III in Q3 2013 in patients at high risk ofCDI. In the U.S., a Fast Track Development Program designation was granted by CBER (Center for Biologics Evaluation and Research). CDI is the most common cause of health-care related infections in the developed world and is increasingly reported globally.

·         SAR231893 (collaboration with Regeneron), an anti IL-4Rα monoclonal antibodywith dual IL-4/IL-13 cytokine antagonism, will enter Phase IIb in mid-2013 in asthma and atopic dermatitis following positive proof of concept data for both indications. These data will be submitted for presentation at medical conferences in 2013.

·         SAR302503: In December, Sanofi announced that the Phase II trial evaluating its JAK2inhibitor in myelofibrosis met its primary endpoint. The data was presented during the 2012 Annual Meeting of the American Society of Hematology. Recruitment of the Phase III JAKARTA study is completed.

·         Aubagio® (teriflunomide): Sanofi has discontinued the TERACLES study. This decision isbased on recruitment challenges and an assessment of changing market dynamics which suggests that combining oral and injectable immunomodulatory platform multiple sclerosis therapies may not be a preferred treatment option. This decision is not related to any safety concern.

·         Ombrabulin: Results of the Phase III study in sarcoma did not demonstrate sufficient clinicalbenefit to support regulatory submissions despite reaching its primary endpoint of progression free survival and the phase II study in ovarian cancer was terminated early based on an interim analysis. There were no substantial safety concerns in these studies. We have informed our partner Ajinomoto of our decision to discontinue this project.

·         SAR245408 (XL 147, partnership with Exelixis): The Phase II trial in endometrial cancer hasbeen discontinued. The study did not demonstrate sufficient clinical benefit to pursue late-stage trials in this indication. SAR245408 is being examined in an ongoing Phase II trial in combination with letrozole in breast cancer and in combination with SAR256212 in a Phase I trial.

Key development milestones expected in the next six months

·         Eliglustat: Phase III results of the ENCORE study evaluating the oral therapy eliglustat vs.Cerezyme® in patients with Gaucher disease are expected in Q1 2013.

·         Otamixaban: Phase III results of the TAO study evaluating otamixaban, the first intravenousdirect and selective factor Xa inhibitor with quick onset/offset, are expected in Q2 2013.

·         SAR302503: Headline results from the Phase III JAKARTA study in myelofibrosis areexpected in Q2 2013.

·         New glargine formulation: The first Phase III headline results in diabetes are expected in Q22013.

·         Iniparib: Headline results from the Phase III in first-line squamous non-small-cell lung cancerare expected in Q2 2013.

 

Key regulatory milestones expected in the next six months

·         Zaltrap® (aflibercept, collaboration with Regeneron): The European Commission decision insecond-line metastatic colorectal cancer is targeted in Q1 2013.

·         Lyxumia® (lixisenatide, licensed from Zealand Pharma): The European Commission decisionin type 2 diabetes is targeted in Q1 2013. The FDA decision on file acceptance in type 2 diabetes in the U.S. is expected in Q1 2013.

·         Aubagio® (teriflunomide): The CHMP opinion for the treatment of relapsing multiple sclerosisis expected in Q1 2013.

·         Lemtrada™1 (alemtuzumab): The CHMP opinion for the treatment of relapsing multiplesclerosis is expected in Q2 2013. The FDA decision on file acceptance is expected in Q1 2013.

·         Kynamro™ (mipomersen sodium, development partnership with Isis Pharmaceuticals): TheFDA decision for the treatment of patients with Homozygous Familial Hypercholesterolemia is expected in Q1 2013. In December, the CHMP adopted a negative opinion for its marketing authorization application for the treatment of patients with Homozygous Familial Hypercholesterolaemia. Genzyme has requested a re-examination of the CHMP Opinion.

·         Vaxigrip® QIV IM (quadrivalent inactivated flu vaccine, intramuscular): The submission ofregulatory file in the EU is expected in Q1 2013.

·         Paediatric hexavalent vaccine (DTP-Hep B-Polio-Hib): The CHMP opinion is expected inQ1 2013.

·         Fluzone® QIV IM (quadrivalent inactivated flu vaccine, intramuscular): The FDA decision isexpected in Q2 2013.
