The company’s pipeline spans 71 R&D projects, which includes 37 new molecular entities and novel vaccines. At least 10 pivotal phase 3 studies are expected to start over the next 12 months and will evaluate new treatments for:


chronic obstructive pulmonary disease and eosinophilic esophagitis (dupilumab1);


autosomal dominant polycystic kidney disease (ADPKD), a rare kidney disease (venglustat);


type 2 diabetes (efpeglenatide, a once-weekly GLP-1 agonist);


obesity (a GLP-1/GCG dual agonist);


primary progressive multiple sclerosis (alemtuzumab), and;


first line NSCLC2 (cemiplimab).
Regulatory filings expected in the next 12 months include two investigational cancer drugs (cemiplimab and isatuximab), a novel therapy for type 1 diabetes (sotagliflozin) and a potential treatment for uncontrolled, persistent asthma (dupilumab).

"We have seen significant advancement on our ambition to sustain innovation in R&D, with the development of leading technology platforms and proof of concept demonstrated in multiple high-potential projects in late stage trials. We are confident this portfolio will be the foundation for Sanofi’s future long-term growth," said Olivier Brandicourt, MD, Chief Executive Officer at Sanofi.

As a key pillar of the 2020 Roadmap, the new Sanofi R&D model is based on three key strategic shifts:


From small molecules to biologics;


From mono-targeting to multi-targeting compounds; and


From licensing to proprietary assets.

The company has continuously adapted its R&D model in recent years to deliver greater efficiency and excellence in development, resulting in a major uplift in productivity. Since 2016, consistent with the three key strategic shifts outlined above, Sanofi has placed increasing emphasis on developing proprietary technology platforms, including multi-specific antibodies (bi- & tri-specific), siRNA, trigonal peptides, dual and triple agonists, and PRR-Antibody conjugates. It has also leveraged external expertise in targeted platforms such as mRNA mixtures and Nanobodies.

"We aim to advance multi-targeting therapeutic approaches for core disease pathways that have the potential to attack more than one disease at a time or bring improved risk benefit in the treatment of a single disease," said Elias Zerhouni, MD, Global Head of R&D at Sanofi. "2018 will be an important year as we expect multiple milestones for Sanofi’s late-stage pipeline, made possible through the prioritization principles we have consistently applied to our early-stage research programs."

Building a competitive position in Specialty Care

Immunology

Sanofi is strengthening its specialty care portfolio and has executed launches in its fast-growing immunology franchise. Dupilumab, which we are developing in collaboration with Regeneron, has potential across multiple indications. Phase 3 trials for uncontrolled, persistent asthma recently demonstrated a potentially clinically important profile among biologic treatments. Submission in this important indication is expected before the end of 2017. Clinical development is underway in nasal polyposis, eosinophilic esophagitis, food allergies and in pediatric populations in most of these indications. Additionally, phase 3 development for dupilumab is now planned in chronic obstructive pulmonary disease (COPD). Sanofi, in collaboration with Regeneron, also expects to bring SAR440340, an anti-IL-33 antibody, which has the potential for a broader spectrum of immune modulation, into phase 2 in atopic dermatitis, asthma and COPD in 2018, alone or in combination with dupilumab.

Oncology

Sanofi is committed to re-building its position in oncology and has made major progress in the past two years. This strategy is starting to deliver and we anticipate 14 new proof-of-concept studies to be initiated, four potential proof-of-concept readouts, six phase one starts and three BLA/ MAA submissions in 2018. Cemiplimab is an investigational PD-1 checkpoint inhibitor and the

2
backbone of our checkpoint immuno-oncology strategy with our partner Regeneron. It is being studied in cutaneous squamous cell carcinoma (CSCC), for which it was granted "Breakthrough Therapy" designation by the U.S. Food and Drug Administration (FDA). Topline results show high and durable response rates (overall response rate 46.3%) in a pivotal Phase 2 study in 82 patients with advanced CSCC. This positive data has resulted in the initiation of a rolling BLA submission, with completed submission expected in Q1 2018. The development program also includes large or untapped opportunities in immuno-oncology, such as basal cell carcinoma, cervical cancer, and first line lung cancer.
Isatuximab is a Sanofi investigational antiCD38 monoclonal antibody with a first regulatory submission expected in 2018 for relapsed refractory multiple myeloma (RRMM). Beyond multiple myeloma, and building on the emerging evidence that CD38 inhibition may reverse resistance to PD-L1, isatuximab will be studied in combination with cemiplimab or other immuno-oncology agents. Sanofi will also present early research programs for its Selective Estrogen Receptor Degrader (SERD) and TGF-beta program to overcome PD-1 resistance.

Multiple Sclerosis

In multiple sclerosis (MS), Sanofi plans to build on the proven long-term clinical profile of Lemtrada (alemtuzumab) by initiating a Phase 3 study in 2018 for alemtuzumab in patients with primary progressive multiple sclerosis (PPMS). Consistent with Sanofi’s rigorous prioritization methodology, the company will deprioritize GLD-52 in this indication in favor of alemtuzumab. In addition, Sanofi, in collaboration with Principia, will be developing a novel Bruton’s tyrosine kinase (BTK) inhibitor, designed to access the brain and spinal cord by crossing the blood-brain barrier and impact immune cell and brain cell signaling. It is currently being studied in MS with potential applications in other central nervous system diseases3.
Sustaining leadership in Rare Disease, Diabetes & Cardiovascular and Vaccines

Rare Disease
Sanofi’s Rare Disease pipeline is structured with the goal of sustaining innovation in lysosomal storage disorders, while also expanding strategically into related conditions. Clinical development programs include venglustat, an oral inhibitor of glucosylceramide synthase, in Fabry Disease, Gaucher Disease Type 3, GBA Parkinson’s Disease and autosomal dominant polycystic kidney disease (ADKPD). Late-stage/pivotal programs include olipudase, a first-in-class enzyme replacement therapy (ERT) for the non-neurological manifestations of acid sphingomyelinase deficiency (ASMD), and avalglucosidase alfa, a novel ERT for Pompe disease. Finally, through a strategic collaboration with Alnylam, we are advancing the development of patisiran for hATTR4 amyloidosis and fitusiran for hemophilia A and B, with and without inhibitors.

hATTR = Hereditary Transthyretin-Mediated Amyloidosis

Diabetes & Cardiovascular
Sanofi is committed to sustaining a leadership position in diabetes and expanding into adjacent co-morbidities. Its late-stage diabetes pipeline includes sotagliflozin, an investigational SGLT-1/2 inhibitor being developed in collaboration with Lexicon, and efpeglenatide, a once-weekly GLP-1 being developed in collaboration with Hanmi, both of which potentially offer unique patient advantages. Additionally, Sanofi is leveraging its novel peptide incretin platform to develop breakthrough assets for diabetes, obesity and non-alcoholic steatohepatitis (NASH). The lead compound is a dual agonist of GLP-1/GCG which has shown highly competitive weight loss in the clinic and is expected to enter phase 3 in obesity in 2018. A phase 2 study in NASH is also due to start in 2018.

In cardiovascular, Sanofi continues to work in collaboration with Myokardia on therapeutic options for genetic forms of cardiomyopathy. The lead compound is mavacamten, an oral modulator of cardiac myosin, which is in phase 2 for HCM5 and is expected to start a registrational phase 2b/3 study in 2018.

Vaccines
Sanofi has six key vaccine projects currently in development, and priority disease areas include influenza, meningitis and respiratory syncytial virus (RSV). RSV is the leading cause of infant viral mortality and represents a new potential category for Sanofi. The company is taking a complementary dual approach to RSV with a monoclonal antibody in phase 2, in collaboration with MedImmune, and a vaccine in phase 1.

Webcast details
The event will be webcast live on Sanofi’s website at 8:30 am CET/2:30 am EST. The webcast details and full presentation will be made available on Sanofi’s Investor Relations webpage and an Appendix compiling all Sanofi studies registered on clinicaltrials.gov will also be published.

Regeneron and Sanofi Announce Positive Topline Pivotal Results for PD-1 Antibody Cemiplimab in Advanced Cutaneous Squamous Cell Carcinoma

On December 13, 2017 Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi reported positive topline results from a pivotal Phase 2 clinical study of cemiplimab in 82 patients with advanced cutaneous squamous cell carcinoma (CSCC), the second deadliest skin cancer after melanoma (Press release, Regeneron, DEC 13, 2017, View Source [SID1234522608]). Cemiplimab, an investigational human antibody targeting PD-1 (programmed cell death protein 1), demonstrated an overall response rate (ORR) of 46.3%, as determined by independent review. The median duration of response (DOR) had not yet been reached at the data cut-off point (32 of 38 responses are ongoing). At the time of this analysis, all patients had a minimum follow up of 6 months. The safety profile in the study was generally consistent with approved anti-PD-1 agents.

These pivotal data will form the basis of a rolling Biologics License Application (BLA) submission to the U.S. Food and Drug Administration (FDA), which has been initiated and is expected to be completed in the first quarter of 2018. A rolling BLA submission allows for portions of the regulatory application to be submitted to the FDA as they are completed. A submission to the European Medicines Agency (EMA) is also expected to be completed in the first quarter of 2018. These data confirm the positive Phase 1 clinical trial expansion cohort results reported at the 2017 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting, which led to a Breakthrough Therapy Designation for cemiplimab in advanced CSCC in September 2017.

"For patients with CSCC that cannot be cured by surgery or radiation, there are no FDA-approved treatment options, and advanced CSCC is responsible for 3,900 to 8,800 deaths per year in the U.S.," said Israel Lowy, MD, PhD, Vice President of Global Clinical Development and Head of Translational Science and Clinical Oncology, Regeneron. "This is the largest prospective study ever conducted in this disease, and we are pleased that many patients were able to achieve deep and durable responses with cemiplimab monotherapy. The high and durable response rates seen in this study are particularly notable given that the study enrolled patients regardless of biomarker status."

The efficacy data reported today include results from 82 patients in the Phase 2 EMPOWER-CSCC 1 study. Approximately two-thirds of patients had progressed after prior systemic chemotherapy or radiation.

"EMPOWER-CSCC 1 was initiated in 2016 and has enrolled rapidly, underscoring the serious unmet need in advanced CSCC," said Elias Zerhouni, MD, President, Global R&D, Sanofi. "We look forward to working with regulatory agencies globally to bring this important therapy to advanced CSCC patients as quickly as possible. We continue to rapidly advance a broad development program to evaluate cemiplimab both as monotherapy and combination across a number of solid tumor and blood cancers."

EMPOWER-CSCC 1 is a single-arm, open-label clinical trial and remains active. Enrollment is complete in the study arm of patients with metastatic CSCC receiving a 3 mg/kg dose of cemiplimab every two weeks. Enrollment continues in the remaining two study arms of patients with metastatic CSCC receiving a 350 mg flat dose of cemiplimab every three weeks and patients with locally advanced and unresectable CSCC receiving a 3 mg/kg dose of cemiplimab every two weeks.

Updated results from both the EMPOWER-CSCC 1 and the Phase 1 clinical trial will be submitted for presentation at a 2018 medical congress.

Cemiplimab is being jointly developed by Regeneron and Sanofi under a global collaboration agreement, and was invented by Regeneron using the company’s proprietary VelocImmune technology that yields optimized fully-human antibodies. Cemiplimab is currently under clinical development, and its safety and efficacy has not been fully evaluated by any regulatory authority.

About Cutaneous Squamous Cell Carcinoma (CSCC)
CSCC is the second most common type of skin cancer in the United States. Although CSCC has a good prognosis when caught early, it can prove especially difficult to treat when it progresses to advanced stages. Patients at this stage can be disfigured due to multiple surgeries to remove CSCC tumors on the head, neck and other parts of the body. CSCC is the second deadliest skin cancer after melanoma and is responsible for the most deaths among non-melanoma skin cancer patients.

Eleven Biotherapeutics Announces Chief Scientific Officer to Chair a Session at the Antibody Engineering and Therapeutics Meeting

"Checkpoint inhibitors are a significant step forward in the quest to engage the patient’s immune system in the fight against cancer. Checkpoint inhibitors function by blocking the signals that cancers use to inhibit the immune system. However, for checkpoint inhibitors to be effective, they require the presence of an active immune response against the cancer. There is broad recognition of the potential for tumor-targeted payloads, such as Eleven’s Targeted Protein Therapeutics (TPTs), to provide this spark to the immune system and act synergistically with checkpoint inhibitors," said Dr. Gregory Adams, Chief Scientific Officer of Eleven Biotherapeutics. "Earlier this year at the American Association of Cancer Research Conference, we presented data which supports this potential, demonstrating that TPTs induce immunogenic cell death as evidenced by the presence of damage-associated molecular patterns. Our collaboration with the National Cancer Institute and AstraZeneca aims to build on this evidence."

Title: Antibody-Drug Conjugates & Fusion Proteins
Date: Wednesday, December 13, 2017
Time: 8:10 am – 12:00 pm PT
Location: Manchester Grand Hyatt; San Diego, CA

About Vicinium

Vicinium is manufactured as a single protein anti-epithelial cell adhesion molecule (anti-EpCAM) fusion protein fused with Pseudomonas Exotoxin A (ETA) designed to specifically target and deliver a potent anti-cancer payload directly into tumor cells. It is constructed with a stable, genetically-engineered linker to ensure its potent protein payload remains attached until it is internalized by the cancer cell, which is believed to decrease the risk of toxicity to healthy tissues thereby improving the compound’s safety. Vicinium’s one-step manufacturing process offers significant cost advantages and results in the production of a homogenous product, with less batch-to-batch variability than most antibody drug conjugates. Vicinium is currently in a Phase 3 registration clinical trial for the treatment of high-grade non-muscle invasive bladder cancer (NMIBC) in patients who have previously received two courses of Bacillus Calmette-Guérin (BCG) and whose disease is now BCG-unresponsive. Eleven Biotherapeutics intends to enroll 134 subjects in the trial, including 77 subjects with carcinoma in situ (CIS), at over 70 centers in the United States and Canada. Primary and secondary endpoints include complete response (CR) in CIS subjects, time to disease recurrence and event free survival. The Company expects to complete patient enrollment in the first quarter of 2018 and to report topline three-month data in mid-2018.
