R&D update

Consult Appendix 6 for full overview of Sanofi's R&D pipeline

Regulatory update

Regulatory updates since April 26, 2019 include the following:

• In July, the U.S. Food and Drug Administration (FDA) accepted for review the Biologics License Application (BLA) for isatuximab for the treatment of patients with relapsed/refractory multiple myeloma (RRMM). The target action date for the FDA decision is April 30, 2020.
• In June, Libtayo^® (cemiplimab, collaboration with Regeneron) was approved in the European Union (EU) for the treatment of adults with metastatic or locally advanced cutaneous squamous cell carcinoma (CSCC) who are not candidates for curative surgery or curative radiation.
• In June, the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for Dupixent^® (dupilumab, collaboration with Regeneron) recommending extending its approval in the EU to include adolescents 12 to 17 years of age with moderate-to-severe atopic dermatitis who are candidates for systemic therapy.
• The FDA accepted for review the BLA for Sanofi's MenQuadfi™ Meningococcal Polysaccharide Tetanus Toxoid Conjugate Vaccine candidate to help prevent meningococcal meningitis. The target action date for the FDA decision is April 25, 2020.
• In June, the FDA approved Dupixent^® for the treatment of chronic rhinosinusitis with nasal polyposis (CRSwNP) in adults whose disease is not adequately controlled.
• In May, the European Commission approved Dupixent^® for use in adults and adolescents 12 years and older as an add-on maintenance treatment for severe asthma with type 2 inflammation characterized by raised blood eosinophils and/or raised fractional exhaled nitric oxide (FeNO), who are inadequately controlled with high dose inhaled corticosteroid (ICS) plus another medicinal product for maintenance treatment.
• In May, SAR341402 (insulin aspart), a rapid acting insulin, was submitted to the EMA for the treatment of Type I and II diabetes.
• In April, the FDA approved Praluent^® (collaboration with Regeneron) to reduce the risk of heart attack, stroke, and unstable angina requiring hospitalization in adults with established cardiovascular disease.

At the end of July 2019, the R&D pipeline contained 83 projects, including 34 new molecular entities in clinical development. 35 projects are in phase 3 or have been submitted to the regulatory authorities for approval.

Portfolio update

Phase 3:

• Topline results from three Phase 3 trials of Zynquista™ (sotagliflozin) in adults with type 2 diabetes from the InSynchrony clinical program were announced on July 26. Given the primary endpoint results of blood sugar control (HbA1c) reduction in the SOTA-CKD3 and SOTA-CKD4 studies, Sanofi provided notice to Lexicon that it is terminating the collaboration to develop, manufacture, and commercialize Zynquista™ in all ongoing global type 1 and type 2 diabetes programs. At this time, the ongoing Phase 3 clinical trials will continue and there will be no immediate changes. Sanofi has expressed willingness to work with Lexicon to ensure a smooth transition of the studies. Sanofi remains committed to working and supporting the investigators and patients enrolled in the studies while next steps are discussed with Lexicon.
• Results from a phase 3 study evaluating Soliqua^®/Suliqua^® (insulin glargine 100 Units/mL and lixisenatide) in adults with type 2 diabetes inadequately controlled by GLP-1 receptor agonist (GLP-1 RA) treatments were presented at the American Diabetes Association (ADA) Scientific Sessions in June. The study met the primary objective by demonstrating a statistically superior reduction of average blood sugar level (HbA1c) after 26 weeks, compared with continuing GLP-1 RA treatment.
• Pivotal phase 3 ICARIA-MM trial results were presented at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting in June and demonstrated that isatuximab added to pomalidomide and dexamethasone (isatuximab combination therapy) showed statistically significant improvements compared to pomalidomide and dexamethasone (pom-dex) alone in patients with relapsed/refractory multiple myeloma (RRMM).
• A phase 3 study evaluating cemiplimab, a PD-1 inhibitor, in adjuvant treatment for Cutaneous Squamous Cell Carcinoma (CSCC) started.
• Dupilumab , moved into phase 3 in Chronic Obstructive Pulmonary Disease (COPD).
• Fitusiran , a siRNA inhibitor targeting AT3, entered phase 3 for pediatric hemophilia.
• Nirsevimab ( SP0232, collaboration with Medimmune), a monoclonal antibody, entered phase 3 for respiratory syncytial virus (RSV)

Phase 2:

• SAR440340/REGN3500 (collaboration with Regeneron), an investigational IL-33 antibody, met the primary endpoint of improvement in loss of asthma control when comparing monotherapy to placebo in a phase 2 proof-of-concept trial The trial also met a key secondary endpoint, demonstrating SAR440340 monotherapy significantly improved lung function compared to placebo. Patients treated with Dupixent^® monotherapy did numerically better than SAR440340 across all endpoints, although the trial was not powered to show differences between active treatment arms. The combination of SAR440340 and Dupixent^® did not demonstrate increased benefit compared to Dupixent^® monotherapy in this trial.

Phase 1:

• A phase 1 trial evaluating SAR441255, a trigonal GLP1R/GIPR/GCGR agonist was initiated.
• SAR441236 , a tri-specific neutralizing anti-HIV mAb, entered into phase 1.

An additional seven research projects have been discontinued to enhance the company's focus on delivering first and best in class medicines

Collaboration

In June, Sanofi and Google announced that they will establish a new virtual Innovation Lab with the ambition to transform how future medicines and health services are delivered by tapping into the power of emerging data technologies. The collaboration aims to change how Sanofi develops new treatments and will focus on three key objectives: to better understand patients and diseases, to increase Sanofi's operational efficiency, and to improve the experience of Sanofi's patients and customers.
