R&D Update

Regulatory update

Regulatory updates since the publication of the fourth quarter results on February 9, 2016 include the following:

• In February, the U.S. Food and Drug Administration (FDA) accepted the New Drug Application (NDA) for the investigational fixed-ratio combination of basal insulin glargine and GLP-1 receptor agonist lixisenatide for the treatment of adults with type 2 diabetes. The FDA decision is anticipated in August 2016. In March, the FDA announced that on May 25, 2016, the Endocrinologic and Metabolic Drugs Advisory Committee will review the NDA for the investigational fixed-ratio combination of basal insulin glargine and lixisenatide and investigational lixisenatide. InEurope, Sanofi submitted the dossier of this fixed-ratio combination to health authorities in March.

• In February, the new hexavalent pediatric vaccine, PR5i (DTP-HepB-Polio-Hib), was granted a Marketing Authorization in EU.

At the end of April 2016, the R&D pipeline contained 46 pharmaceutical new molecular entities (excluding Life Cycle Management) and vaccine candidates in clinical development of which 15 are in Phase III or have been submitted to the regulatory authorities for approval.

Portfolio update

Phase III:

• The Data Monitoring Committee (DMC) of the ODYSSEY OUTCOMES study for Praluent^® has completed the first interim analysis based on unblinded study data. In addition to the review of the safety data, the DMC performed a futility assessment and recommended the study continue with no changes. Sanofi remains blinded to the actual results of this analysis. The second interim analysis for futility and overwhelming efficacy potentially could occur in the second half of 2016 when 75% of the targeted number of primary events have occurred

• In March, Sanofi and Regeneron announced positive topline results from the Phase III ODYSSEY ESCAPE trial evaluating Praluent^® (alirocumab) Injection in patients with an inherited form of high cholesterol known as heterozygous familial hypercholesterolemia, whose cholesterol levels required chronic, weekly or bi-weekly apheresis therapy.

• In March, Sanofi and Regeneron announced that a Phase III monotherapy study, SARIL-RA-MONARCH, met its primary endpoint demonstrating that sarilumab was superior to adalimumab (marketed by AbbVie as Humira^®) in improving signs and symptoms in patients with active rheumatoid arthritis at Week 24.

• In April, Sanofi and Regeneron announced positive topline results from two placebo-controlled Phase 3 studies known as LIBERTY AD SOLO 1 and SOLO 2, evaluating investigational dupilumab in adult patients with inadequately controlled moderate-to-severe atopic dermatitis. In the studies, treatment with dupilumab as monotherapy significantly improved measures of overall disease severity, skin clearing, itching, quality of life, and mental health.

• The second generation meningococcal ACYW conjugate vaccine, Men Quad TT, with a broader age indication (from infants to the elderly) entered into Phase III.

Phase II:

• In March, data from a Phase I/II clinical study, NEO1, evaluating the investigational novel enzyme replacement therapy neoGAA in 24 patients with late-onset Pompe disease were presented at WORLD Symposium 2016. The safety and efficacy data from this study support further development of the therapy. Sanofi plans to begin enrolling patients in a pivotal Phase 3 trial for neoGAA in Q2 2016.

• SAR422459, ABC4A gene therapy, entered in Phase IIa in Stargardt Disease, a rare eye disease.
