R&D update

Regulatory update

Regulatory updates since July 31, 2018 include the following:

• In October, the U.S. Food and Drug Administration approved Dupixent^® (dupilumab, collaboration with Regeneron) as an add-on maintenance therapy in patients with moderate-to-severe asthma aged 12 years and older with an eosinophilic phenotype or with oral corticosteroid-dependent asthma.
• In October, the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for the marketing authorization of Dengvaxia^® (dengue tetravalent vaccine), recommending its approval in Europe.
• In September, Libtayo^® (cemiplimab-rwlc, collaboration with Regeneron) was approved in the U.S. for the treatment of patients with metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC who are not candidates for curative surgery or curative radiation.
• In September, Sanofi and Regeneron announced that the U.S. Food and Drug Administration (FDA) accepted for review a supplemental Biologics License Application (sBLA) for Praluent^® (alirocumab, collaboration with Regeneron). The sBLA outlines a proposed update to the prescribing information to include the effect of Praluent^® in reducing the overall risk of major adverse cardiovascular events.
• In September, the European Commission granted marketing authorization for Cablivi^® (caplacizumab) for the treatment of adults with acquired thrombotic thrombocytopenic purpura (aTTP). In addition, the FDA accepted for priority review the Biologics License Application for caplacizumab for adults experiencing an episode of aTTP.
• Dupixent^® (dupilumab, collaboration with Regeneron) was submitted to the FDA and to the EMA for the treatment of atopic dermatitis for adolescent patients (aged 12-17 years).

At the end of October 2018, the R&D pipeline contained 94 projects including 42 new molecular entities in clinical development. 40 projects are in phase 3 or have been submitted to the regulatory authorities for approval.

Portfolio update

Phase 3:

• In October Sanofi and Regeneron announced that two pivotal Phase 3 placebo-controlled trials evaluating Dupixent^® (dupilumab) in adults with inadequately-controlled chronic rhinosinusitis with nasal polyps met all primary and secondary endpoints. Detailed results from these trials will be submitted for presentation at future medical meetings, and will form part of the companies’ regulatory submissions.
• In September, detailed results from a pivotal Phase 3 trial showing Dupixent^® (dupilumab) monotherapy demonstrated a significant improvement in signs and symptoms of atopic dermatitis and certain quality of life measures in adolescent patients with moderate-to-severe atopic dermatitis, were presented at the European Academy of Dermatology and Venereology (EADV) Congress.
• The results of the first Phase 3 evaluating MenQuadTT, a quadrivalent meningococcal conjugated vaccine, were presented in September at the International Pathogenic Neisseria Conference. This study demonstrated that MenQuadTT was safe and as immunogenic as Menactra^® when administered as a booster dose in adolescents and adults (15 yrs and above) primed with quadrivalent meningococcal conjugated vaccines
• Results from a Phase 3 trial for Fluzone^® High-Dose Quadrivalent showed comparable safety and immunogenicity to Fluzone^® High-Dose Trivalent. The primary endpoint was to determine if the quadrivalent high-dose vaccine induces an immune response that is non-inferior to that produced by Fluzone^® High-Dose Trivalent. The key secondary endpoints were to evaluate the safety of the vaccine and demonstrate that each B strain in the quadrivalent high-dose vaccine induces an immune response that is superior to that produced by the trivalent high-dose vaccine not containing the corresponding B virus type.
• A Phase 3 trial evaluating isatuximab was initiated in newly-diagnosed transplant-eligible multiple myeloma patients (in conjunction with the German Multiple Myeloma Group, GMMG).
• Two Phase 3 trials, evaluating sarilumab (collaboration with Regeneron) for the treatment of Giant Cell arteritis and Polymyalgia Rheumatica, are in the process of being initiated.
• A Phase 3 trial evaluating Dupixent^® (dupilumab) in Eosinophilic esophagitis has been initiated.
• Sanofi will not initiate a Phase 3 program to evaluate Lemtrada^® in primary progressive multiple sclerosis.

Phase 2:

• A Phase 2 study evaluating the combination of isatuximab and atezolizumab (PD-L1 monoclonal antibody from Roche) was initiated in advanced malignancies.
• A Phase 2 Study of AR101 (collaboration with Aimmune) with adjunctive dupilumab was initiated in peanut-allergic patients (ages 6-17).
• Following the results of the Phase 2b RESPIRE study, Sanofi decided not to pursue further development of ALX0171 (anti RSV Nanobody - Respiratory Syncitial Virus ) in the infant population. While results were positive for the primary endpoint of anti-viral efficacy and target exposure was achieved, consistent clinical efficacy was not observed across secondary endpoints. Sanofi will continue the phase 2 program (BREEZE) in adult patients who have received hematopoietic stem cell transplantation.

Phase 1:

• SAR442720, an SHP2 inhibitor (collaboration with Revolution Medicines), entered Phase 1 in solid tumors.
• SAR440234, a T-cell engaging multi-specific monoclonal antibody, entered Phase 1 for the treatment of leukemia.
