CAMBRIDGE, Mass., Sept. 9, 2020 /PRNewswire/ --?Sanofi Genzyme today announced that new data from across the company's neurology portfolio will be presented at MSVirtual2020, the 8th Joint Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) - European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) Meeting from 11-13 September 2020. The congress will feature new data relating to tolebrutinib (SAR442168), an investigational oral, brain-penetrant, selective small molecule inhibitor of Bruton's tyrosine kinase (BTK). ??The poster, and a platform presentation, extend previous findings on the role of BTK in microglia and the potential of brain-penetrant BTK inhibitors to block microglia-driven neuroinflammation implicated in MS disease progression.? Tolebrutinib is the proposed international nonproprietary name for SAR442168. In addition, several posters and platform presentations highlight studies evaluating safety, efficacy and investigational uses of approved therapies AUBAGIO^??(teriflunomide) and LEMTRADA^??(alemtuzumab) reinforcing the consistent, positive clinical profiles of these two treatment options. Presentations at MSVirtual2020: 8th Joint ACTRIMS-ECTRIMS Meeting include: ^??In vivo studies were performed with the tool compound PRN2675, the in vitro microglia gene signature study (#P0311) was performed with SAR442168 About tolebrutinib (SAR442168) Tolebrutinib is an investigational, oral, brain-penetrant, selective small-molecule inhibitor of BTK. Tolebrutinib has shown BTK binding as well as cerebrospinal fluid exposure in Phase 1 studies. Sanofi obtained global rights to develop and commercialize tolebrutinib under a license agreement with Principia Biopharma, Inc.

Tolebrutinib is currently under clinical development, and its safety and efficacy have not been reviewed by any regulatory authority. AUBAGIO?(teriflunomide) IMPORTANT SAFETY INFORMATION AND INDICATION FOR U.S. PATIENTS AUBAGIO^??(teriflunomide) is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults. IMPORTANT SAFETY INFORMATION DO NOT TAKE AUBAGIO IF YOU:

• ?Have severe liver problems. AUBAGIO may cause serious liver problems, which can be life-threatening.?Your risk may be higher if you take other medicines that affect your liver. Your healthcare provider should do blood tests to check your liver within 6 months before you start AUBAGIO and monthly for 6 months after starting AUBAGIO.

After stopping AUBAGIO, continue to use effective birth control until you have made sure your blood levels of AUBAGIO are lowered. If you become pregnant while taking AUBAGIO or within 2 years after stopping, tell your healthcare provider right away and enroll in the AUBAGIO Pregnancy Registry at 1?800?745?4447, option 2.
• ?Are of childbearing potential and not using effective birth control. It is not known if AUBAGIO passes into breast milk.?Your healthcare provider can help you decide if you should take AUBAGIO or breastfeed ? you should not do both at the same time. If you are a man whose partner plans to become pregnant,?you should stop taking AUBAGIO and talk with your healthcare provider about reducing the levels of AUBAGIO in your blood. If your partner does not plan to become pregnant, use effective birth control while taking AUBAGIO.
• ?Have had an allergic reaction to AUBAGIO or a medicine called leflunomide.
• ?Take a medicine called leflunomide for rheumatoid arthritis.

AUBAGIO may stay in your blood for up to 2 years after you stop taking it.?Your healthcare provider can prescribe a medicine that can remove AUBAGIO from your blood quickly. Before taking AUBAGIO, talk with your healthcare provider if you have:?liver or kidney problems; a fever or infection, or if you are unable to fight infections; numbness or tingling in your hands or feet that is different from your MS symptoms; diabetes; serious skin problems when taking other medicines; breathing problems; or high blood pressure. Your healthcare provider will check your blood cell count and TB test before you start AUBAGIO. Talk with your healthcare provider if you take or are planning to take other medicines (especially medicines for treating cancer or controlling your immune system), vitamins or herbal supplements. AUBAGIO may cause serious side effects, including:?reduced white blood cell count ? this may cause you to have more infections; numbness or tingling in your hands or feet that is different from your MS symptoms; allergic reactions, including serious skin problems; breathing problems (new or worsening); and high blood pressure. Patients with low white blood cell count should not receive certain vaccinations during AUBAGIO treatment and 6 months after. Tell your doctor if you have any side effect that bothers you or does not go away. The most common side effects when taking AUBAGIO include:?headache; diarrhea; nausea; hair thinning or loss; and abnormal liver test results.?These are not all the side effects of AUBAGIO. Tell your healthcare provider about any side effect that bothers you. Consult your healthcare provider if you have questions about your health or any medications you may be taking, including AUBAGIO.

LEMTRADA (alemtuzumab) IMPORTANT SAFETY INFORMATION AND INDICATION FOR U.S. PATIENTS LEMTRADA is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include relapsing-remitting disease and active secondary progressive disease, in adults. Since treatment with LEMTRADA can increase your risk of getting certain conditions and diseases, LEMTRADA is generally prescribed for people who have tried 2 or more MS medicines that have not worked well enough. LEMTRADA is not recommended for use in patients with clinically isolated syndrome (CIS). It is not known if LEMTRADA is safe and effective for use in children under 17 years of age. IMPORTANT SAFETY INFORMATION LEMTRADA can cause serious side effects including: Serious autoimmune problems:?Some people receiving LEMTRADA develop a condition where the immune cells in your body attack other cells or organs in the body (autoimmunity), which can be serious and may cause death.

Call your healthcare provider right away if you have any of the following symptoms: swelling of your legs or feet; blood in the urine (red or tea?colored urine); decrease in urine; fatigue; coughing up blood It is important for you to have blood and urine tests before you receive, while you are receiving and every month for 4 years or longer, after you receive your last LEMTRADA infusion. Serious infusion reactions:?LEMTRADA can cause serious infusion reactions that may cause death. Serious infusion reactions may happen while you receive, or up to 24 hours or longer after you receive LEMTRADA.

• You will receive your infusion at a healthcare facility with equipment and staff trained to manage infusion reactions, including serious allergic reactions, and urgent heart or breathing problems. You will be watched while you receive, and for 2 hours or longer after you receive, LEMTRADA. If a serious infusion reaction happens while you are receiving LEMTRADA, your infusion may be stopped. Tell your healthcare provider right away if you have any of the following symptoms of a serious infusion reaction during the infusion, and after you have left the healthcare facility:

• swelling in your mouth or throat
• trouble breathing
• weakness
• fast, slow, or irregular heartbeat
• chest pain
• rash

To lower your chances of getting a serious infusion reaction, your healthcare provider will give you a medicine called corticosteroids before your first 3 infusions of a treatment course. You may also be given other medicines before or after the infusion to try to reduce your chances of having these reactions or to treat them if they happen. Stroke and tears in your arteries that supply blood to your brain (carotid and vertebral arteries):?Some people have had serious and sometimes deadly strokes and tears in their carotid or vertebral arteries within 3 days of receiving LEMTRADA. Get help right away if you have any of the following symptoms that may be signs of a stroke or tears in your carotid or vertebral arteries:

• drooping of parts of your face
• weakness on one side
• sudden severe headache
• difficulty with speech
• neck pain

Certain cancers:?Receiving LEMTRADA may increase your chance of getting some kinds of cancers, including thyroid cancer, skin cancer (melanoma), and blood cancers called lymphoproliferative disorders and lymphoma.

• swelling in your neck
• pain in front of neck
• hoarseness or other voice changes that do not go away
• trouble swallowing or breathing
