Evrysdi (risdiplam) data continue to demonstrate long-term efficacy and safety in a broad population of people with spinal muscular atrophy

Longer-term efficacy and safety for Enspryng (satralizumab-mwge) in neuromyelitis optica spectrum disorder reinforce previously seen results

Additional data across neurological disorders, including Alzheimer’s disease, help advance the scientific understanding of these conditions and the potential impact of early treatment

South San Francisco, CA — March 24, 2022 —

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced new data for its approved and investigational medicines across neurological disorders will be presented at the 74th American Academy of Neurology (AAN) Annual Meeting being held April 2-7 in Seattle and virtually April 24-26, 2022. These data include twenty two abstracts highlighting Genentech’s expansive neuroscience portfolio across multiple therapeutic areas, including Ocrevus^® (ocrelizumab) in relapsing, secondary and primary progressive multiple sclerosis (RMS, SPMS and PPMS), Evrysdi™ (risdiplam) in spinal muscular atrophy (SMA), Enspryng™ (satralizumab-mwge) in neuromyelitis optica spectrum disorder (NMOSD), along with data from investigational programs in Alzheimer’s disease (AD).

“The longer-term efficacy and safety data for Ocrevus, Evrysdi and Enspryng, as well as findings from diverse and underrepresented populations, demonstrate the significant impact of our expanding neuroscience portfolio,” said Levi Garraway, M.D., Ph.D. chief medical officer and head of Global Product Development. “We remain committed to advancing the science and improving the lives of people living with neurological conditions.”

Multiple Sclerosis (MS)

Genentech will present 11 abstracts on MS and Ocrevus at AAN. New data from the one-year interim analysis of CONSONANCE, a first-of-its-kind open-label Phase III trial, will show the treatment effect of Ocrevus in the complete spectrum of progressive MS – SPMS and PPMS – with novel composite disability endpoints.

Additionally, an analysis of a U.S. claims database will highlight treatment disparities between Black and Hispanic/Latino-American patients and non-Hispanic white patients in the two years after diagnosis. Addressing health inequity and inclusion in research is central to Genentech’s mission to improve patient health outcomes. The insights from the data presented at AAN reinforce the importance of Genentech’s CHIMES trial evaluating Ocrevus in Black and Hispanic patients with MS, which is now fully enrolled across sites in the U.S. and Kenya.

Spinal Muscular Atrophy (SMA)

Genentech will present encore data from the clinical development program for Evrysdi, including 3-year data from SUNFISH Part 1 and 2, highlighting the long-term efficacy and safety of Evrysdi in people aged 2-25 years with Type 2 or Type 3 SMA. In addition, updated interim efficacy data from the RAINBOWFISH study in presymptomatic infants with SMA will be presented. The clinical development program represents the broad real-world spectrum of people living with SMA from newborn babies to people aged 60 years old.

Genentech will also share the design of the new MANATEE trial, a multicenter, randomized, placebo-controlled, double-blind trial studying GYM329, an investigational anti-myostatin, in combination with Evrysdi.

Neuromyelitis Optica Spectrum Disorder (NMOSD)

Genentech will present encore long-term efficacy and safety data from the Enspryng SAkuraSky and SAkuraStar studies. These data reinforce the previously observed efficacy and safety of Enspryng, the first and only approved treatment designed to target and inhibit the IL-6 receptor activity and that can be administered subcutaneously every four weeks at home after training from a healthcare provider.

To increase the scientific understanding of NMOSD and improve care for all people living with the condition, Genentech has initiated SAkuraBONSAI, a multicenter, Phase IIIb, international study evaluating Enspryng treatment for people with AQP4-IgG seropositive NMOSD who are treatment naïve, or where prior rituximab (or biosimilar) treatment has failed*; SAkuraBONSAI will further evaluate disease activity and progression using comprehensive imaging, biomarker and clinical assessment.

*It is important to note, rituximab (or any biosimilar) is not approved by regulatory authorities for the treatment of NMOSD.

Alzheimer’s Disease (AD)

Genentech will present updates from its AD clinical program, including baseline characteristics from the Phase III GRADUATE studies in patients with early AD.

In addition, the design of the post-GRADUATE open label rollover study evaluating the long-term safety, tolerability and efficacy of gantenerumab in patients from the GRADUATE 1 and 2 studies will be presented.

For more than two decades, Genentech has been studying and developing gantenerumab, a late-stage investigational subcutaneously-administered monoclonal antibody, for the treatment of AD. Data from the pivotal GRADUATE trials are expected in the fourth quarter of 2022. Gantenerumab is also being evaluated in the Phase III SKYLINE prevention trial to better understand the potential of the investigational therapy to slow disease progression in people with the earliest biological signs of AD.

The full range of data from Genentech’s clinical development program in neuroscience being presented at 2022 AAN include:

About OCREVUS^® (ocrelizumab)

Ocrevus is the first and only therapy approved for both RMS (including RRMS and active, or relapsing, secondary progressive MS [SPMS], in addition to clinically isolated syndrome [CIS] in the U.S.) and PPMS. Ocrevus is a humanized monoclonal antibody designed to target CD20-positive B cells, a specific type of immune cell thought to be a key contributor to myelin (nerve cell insulation and support) and axonal (nerve cell) damage. This nerve cell damage can lead to disability in people with MS. Based on preclinical studies, Ocrevus binds to CD20 cell surface proteins expressed on certain B cells, but not on stem cells or plasma cells, suggesting that important functions of the immune system may be preserved. Ocrevus is administered by intravenous infusion every six months. The initial dose is given as two 300 mg infusions given two weeks apart. Subsequent doses are given as single 600 mg infusions.

Indications and Important Safety Information

What is Ocrevus?
Ocrevus 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
• Primary progressive MS, in adults.

It is not known if Ocrevus is safe or effective in children.

Who should not receive Ocrevus?

Do not receive Ocrevus if you have an active hepatitis B virus (HBV) infection.

Do not receive Ocrevus if you have had a life threatening allergic reaction to Ocrevus. Tell your healthcare provider if you have had an allergic reaction to Ocrevus or any of its ingredients in the past.

What is the most important information I should know about Ocrevus?

Ocrevus can cause serious side effects, including:

Infusion reactions: Infusion reactions are a common side effect of Ocrevus, which can be serious and may require you to be hospitalized. You will be monitored during your infusion and for at least 1 hour after each infusion of Ocrevus for signs and symptoms of an infusion reaction. Tell your healthcare provider or nurse if you get any of these symptoms:

• itchy skin
• rash
• hives
• tiredness
• coughing or wheezing
• trouble breathing
• throat irritation or pain
• feeling faint
• fever
• redness on your face (flushing)
• nausea
• headache
• swelling of the throat
• dizziness
• shortness of breath
• fatigue
• fast heart beat

These infusion reactions can happen for up to 24 hours after your infusion . It is important that you call your healthcare provider right away if you get any of the signs or symptoms listed above after each infusion.

If you get infusion reactions, your healthcare provider may need to stop or slow down the rate of your infusion.

• Infection:
  • Ocrevus increases your risk of getting upper respiratory tract infections, lower respiratory tract infections, skin infections, and herpes infections. Infections are a common side effect, which can be serious. Tell your healthcare provider if you have an infection or have any of the following signs of infection including fever, chills, or a cough that does not go away. Signs of herpes include cold sores, shingles, genital sores, skin rash, pain, and itching. Signs of more serious herpes infection include: changes in vision, eye redness or eye pain, severe or persistent headache, stiff neck, and confusion. Signs of infection can happen during treatment or after you have received your last dose of Ocrevus. Tell your healthcare provider right away if you have an infection. Your healthcare provider should delay your treatment with Ocrevus until your infection is gone.
  • Progressive Multifocal Leukoencephalopathy (PML): Although no cases have been seen with Ocrevus treatment in clinical trials, PML may happen with Ocrevus. PML is a rare brain infection that usually leads to death or severe disability. Tell your healthcare provider right away if you have any new or worsening neurologic signs or symptoms. These may include problems with thinking, balance, eyesight, weakness on 1 side of your body, strength, or using your arms or legs.
  • Hepatitis B virus (HBV) reactivation: Before starting treatment with Ocrevus, your healthcare provider will do blood tests to check for hepatitis B viral infection. If you have ever had hepatitis B virus infection, the hepatitis B virus may become active again during or after treatment with Ocrevus. Hepatitis B virus becoming active again (called reactivation) may cause serious liver problems including liver failure or death. Your healthcare provider will monitor you if you are at risk for hepatitis B virus reactivation during treatment and after you stop receiving Ocrevus.
  • Weakened immune system: Ocrevus taken before or after other medicines that weaken the immune system could increase your risk of getting infections.

• Low Immunoglobulins: Ocrevus may cause a decrease in some types of antibodies. Your healthcare provider will do blood tests to check your blood immunoglobulin levels.

Before receiving Ocrevus, tell your healthcare provider about all of your medical conditions, including if you:

• have ever taken, take, or plan to take medicines that affect your immune system, or other treatments for MS.
• have ever had hepatitis B or are a carrier of the hepatitis B virus.
• have had a recent vaccination or are scheduled to receive any vaccinations.
  • You should receive any required ‘live’ or ‘live-attenuated’ vaccines at least 4 weeks before you start treatment with Ocrevus . You should not receive ‘live’ or ‘live-attenuated’ vaccines while you are being treated with Ocrevus and until your healthcare provider tells you that your immune system is no longer weakened.
  • When possible, you should receive any ‘non-live’ vaccines at least 2 weeks before you start treatment with Ocrevus. If you would like to receive any non-live (inactivated) vaccines, including the seasonal flu vaccine, while you are being treated with Ocrevus, talk to your healthcare provider.
  • If you are pregnant or planning to become pregnant talk to your doctor about vaccinations for your baby, as some precautions may be needed.
• are pregnant, think that you might be pregnant, or plan to become pregnant. It is not known if Ocrevus will harm your unborn baby. You should use birth control (contraception) during treatment with Ocrevus and for 6 months after your last infusion of Ocrevus. Talk with your healthcare provider about what birth control method is right for you during this time.
  • If you become pregnant while taking Ocrevus, talk to your doctor about enrolling in the Ocrevus Pregnancy Registry. You can enroll in this registry by calling 1-833-872-4370 or visiting http://www.Ocrevuspregnancyregistry.com . The purpose of this registry is to monitor the health of you and your baby.
• are breastfeeding or plan to breastfeed. It is not known if Ocrevus passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you take Ocrevus.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

What are the possible side effects of Ocrevus?

About ENSPRYNGTM (satralizumab)

Enspryng, which was designed by Chugai, a member of the Roche Group, is a humanized monoclonal antibody that targets interleukin-6 (IL-6) receptor activity. The cytokine IL-6 is believed to be a key driver in NMOSD disease processes, triggering the inflammation cascade and leading to damage and disability. Enspryng was designed using novel recycling antibody technology. When compared to conventional antibodies, Enspryng’s recycling antibody technology enables the medicine to remain in the bloodstream for a longer period of time and bind repeatedly to its target (the IL-6 receptor) – maximally sustaining IL-6 suppression in a chronic disease like NMOSD and enabling subcutaneous dosing every four weeks.

Positive Phase III results for Enspryng, as both monotherapy and in combination with baseline immunosuppressive therapy, suggest that IL-6 inhibition is an effective therapeutic approach for NMOSD. The Phase III clinical development program for Enspryng includes two studies: SAkuraStar and SAkuraSky.

Enspryng is currently approved in 58 countries, including the United States, Canada, Japan, South Korea and the European Union.

Enspryng has been designated as an orphan drug in the United States, Europe, Japan and Russia. In addition, it was granted Breakthrough Therapy Designation for the treatment of NMOSD by the FDA in December 2018, which is given to treatments that may demonstrate substantial improvement over other available options.
