SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that new data for its approved and investigational medicines for the treatment of neurological disorders will be presented at the 73rd American Academy of Neurology (AAN) Annual Meeting being held virtually April 17-22, 2021. These new data include 23 abstracts highlighting the expanding Genentech neuroscience portfolio across six therapeutic areas, including Evrysdi™ (risdiplam) for spinal muscular atrophy (SMA), Ocrevus® (ocrelizumab) in relapsing and primary progressive multiple sclerosis (RMS and PPMS), investigational Bruton’s tyrosine kinase inhibitor (BTKi) fenebrutinib in Phase III trials for RMS and PPMS, Enspryng™ (satralizumab-mwge) in neuromyelitis optica spectrum disorder (NMOSD), and data from investigational programs in Alzheimer’s disease (AD) and Huntington’s disease (HD).
“Following U.S. FDA and global approvals for our groundbreaking therapies in SMA and NMOSD, Roche and Genentech’s data at AAN reflect our continued commitment to meaningful therapeutic progress for people living with neurological disorders,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “We are proud to collaborate with patient advocates, academia, industry and the broader healthcare community through cutting-edge research and partnerships to advance the scientific understanding of neurological conditions, which have historically been among the hardest disorders to study, diagnose and treat.”
Spinal Muscular Atrophy (SMA)
Genentech will present data from five studies from the Evrysdi clinical development program, which was designed to represent a broad spectrum of people living with SMA. The program includes infants aged 2 months to adults aged 60 years with varying degrees of disability, including people with scoliosis or joint contractures, and those previously treated for SMA with another medication.
New 2-year findings from Part 2 of the Phase II/III FIREFISH trial show longer-term efficacy and safety of Evrysdi in infants with symptomatic Type 1 SMA treated with Evrysdi. This includes the number of infants able to sit without support for 5 and 30 seconds, a key motor milestone not normally seen in the natural course of the disease, as well as data on event-free survival and reduced hospitalizations.
Additional data being presented across Evrysdi’s broad clinical trial program include updated data from the JEWELFISH trial evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of Evrysdi in patients previously treated with SMA-targeting therapies, as well as updated pooled safety analyses from the FIREFISH, SUNFISH, RAINBOWFISH and JEWELFISH trials.
Multiple Sclerosis (MS)
Genentech will present data from its MS franchise, including five presentations covering Ocrevus and results from studies on the investigational BTKi fenebrutinib. Real-world data continue to show the highest persistence and adherence to Ocrevus, the only MS therapy with a twice-yearly dosing schedule, over one year compared to other disease-modifying therapies (DMTs). Additionally, a post-hoc analysis of the ORATORIO Phase III PPMS study will be presented, which suggests Ocrevus significantly slowed atrophied T2-lesion volume accumulation, a subclinical measure of disease progression. Furthermore, interim analysis of the open-label Phase IIIb ENSEMBLE study shows Ocrevus treatment provided consistent benefit over one year in patients who were recently diagnosed with relapsing-remitting multiple sclerosis (RRMS) and had not received prior DMT.
Genentech is continuing to advance the science in MS and is exploring the investigational medicine fenebrutinib. Data from fenebrutinib, a highly selective, non-covalent, reversible oral BTKi, support its safety profile in several autoimmune diseases and high potency, which is encouraging for the ongoing Phase III studies in RMS and PPMS. Fenebrutinib is a dual inhibitor of both B-cell and myeloid lineage-cell activation, which may offer a novel approach to slowing disease progression by targeting both acute and chronic inflammatory aspects of MS.
Neuromyelitis Optica Spectrum Disorder (NMOSD)
Genentech will present five sets of data on adults living with NMOSD. Data from the Phase III SAkuraStar and SAkuraSky clinical trials reinforce the favorable safety and efficacy of this therapy for those living with NMOSD, including patients with concomitant autoimmune diseases (CAIDs).
New longitudinal, observational data from the CIRCLES study, conducted in collaboration with the Guthy-Jackson Charitable Foundation, a patient advocacy organization dedicated to funding research on NMOSD epidemiology, pathogenesis and treatment, also will be presented. The CIRCLES study explored factors that influence treatment change in people living with NMOSD, including those who have experienced only one relapse.
Alzheimer’s Disease (AD)
Genentech will present data on the increased use of home nursing capabilities in the Phase III GRADUATE studies of gantenerumab during the COVID-19 pandemic, which enabled home-bound trial participants to continue dosing to maintain medicine exposure.
Gantenerumab is a late-stage investigational anti-beta-amyloid antibody being evaluated in two Phase III studies (GRADUATE I and II), which are the only late-stage AD clinical trials to offer subcutaneous administration. Data from the studies is expected in 2022.
Huntington’s Disease (HD)
Genentech also will present an analysis of the Enroll-HD study and REGISTRY database, which highlight the role that genetic factors and medical history may have in predicting the rate of disease progression in HD. These data may help advance the understanding of HD and inform future treatment approaches for this rare, neurological condition.
The full range of data from Genentech’s clinical development program in neuroscience being presented at AAN 2021 include:

About spinal muscular atrophy
Spinal muscular atrophy (SMA) is a severe, progressive neuromuscular disease that can be fatal. It affects approximately one in 10,000 babies and is the leading genetic cause of infant mortality. SMA is caused by a mutation of the survival motor neuron 1 (SMN1) gene, which leads to a deficiency of SMN protein. This protein is found throughout the body and is essential to the function of nerves that control muscles and movement. Without it, nerve cells cannot function correctly, leading to muscle weakness over time. Depending on the type of SMA, an individual’s physical strength and their ability to walk, eat or breathe can be significantly diminished or lost.
About Evrysdi™ (risdiplam)
Evrysdi is a survival of motor neuron 2 (SMN2) splicing modifier designed to treat SMA by increasing and sustaining production of the survival of motor neuron (SMN) protein. SMN protein is found throughout the body and is critical for maintaining healthy motor neurons and movement. Evrysdi is administered daily at home in liquid form by mouth or by feeding tube.
The U.S. Food and Drug Administration (FDA) approved Evrysdi for the treatment of SMA in adults and children 2 months of age and older in August of 2020. In March 2021, the European Commission (EC) approved Evrysdi for the treatment of 5q SMA in patients 2 months of age and older, with a clinical diagnosis of SMA Type 1, Type 2 or Type 3 or with one to four SMN2 copies. Evrysdi has been approved in 38 countries and submitted in a further 33 countries.
Evrysdi is currently being evaluated in four multicenter trials in people with SMA:
- FIREFISH (NCT02913482) – an open-label, two-part pivotal clinical trial in infants with Type 1 SMA. Part 1 was a dose-escalation study in 21 infants with the primary objective of assessing the safety profile of Evrysdi in infants and determining the dose for Part 2. Part 2 is a pivotal, single-arm study of Evrysdi in 41 infants with Type 1 SMA treated for 2 years, followed by an open-label extension. Enrollment for Part 2 was completed in November 2018. The primary objective of Part 2 was to assess efficacy as measured by the proportion of infants sitting without support after 12 months of treatment, as assessed in the Gross Motor Scale of the Bayley Scales of Infant and Toddler Development – Third Edition (BSID-III) (defined as sitting without support for 5 seconds). The study met its primary endpoint.
- SUNFISH (NCT02908685) – SUNFISH is a two-part, double-blind, placebo controlled pivotal study in people aged 2-25 years with Types 2 or 3 SMA. Part 1 (n=51) determined the dose for the confirmatory Part 2. Part 2 (n=180) evaluated motor function using total score of Motor Function Measure 32 (MFM-32) at 12 months. MFM-32 is a validated scale used to evaluate fine and gross motor function in people with neurological disorders, including SMA. The study met its primary endpoint.
- JEWELFISH (NCT03032172) – an open-label exploratory trial designed to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) in people with SMA aged 6 months to 60 years who received other investigational or approved SMA therapies for at least 90 days prior to receiving Evrysdi. The study has completed recruitment (n=174).
- RAINBOWFISH (NCT03779334) – an open-label, single-arm, multicenter study, investigating the efficacy, safety, pharmacokinetics and pharmacodynamics of Evrysdi in babies (~n=25), from birth to 6 weeks of age (at first dose) with genetically diagnosed SMA who are not yet presenting with symptoms. The study is currently recruiting.
What is Evrysdi?
Evrysdi is a prescription medicine used to treat spinal muscular atrophy (SMA) in adults and children 2 months of age and older.
It is not known if Evrysdi is safe and effective in children under 2 months of age.
Important Safety Information
- Before taking Evrysdi, patients should tell their healthcare provider about all of their medical conditions, including if they:
- have liver problems
- are pregnant or plan to become pregnant. If patients are pregnant, or are planning to become pregnant, they should ask their healthcare provider for advice before taking this medicine. Evrysdi may harm one’s unborn baby.

About multiple sclerosis
Multiple sclerosis (MS) is a chronic disease that affects nearly one million people in the United States, for which there is currently no cure. MS occurs when the immune system abnormally attacks the insulation and support around nerve cells (myelin sheath) in the brain, spinal cord and optic nerves, causing inflammation and consequent damage. This damage can cause a wide range of symptoms, including muscle weakness, fatigue and difficulty seeing, and may eventually lead to disability. Most people with MS experience their first symptom between 20 and 40 years of age, making the disease the leading cause of non-traumatic disability in younger adults.
Relapsing-remitting MS (RRMS) is the most common form of the disease and is characterized by episodes of new or worsening signs or symptoms (relapses) followed by periods of recovery. Approximately 85% of people with MS are initially diagnosed with RRMS. The majority of people who are diagnosed with RRMS will eventually transition to secondary progressive MS (SPMS), in which they experience steadily worsening disability over time. Relapsing forms of MS (RMS) include people with RRMS and people with SPMS who continue to experience relapses. Primary progressive MS (PPMS) is a debilitating form of the disease marked by steadily worsening symptoms but typically without distinct relapses or periods of remission. Approximately 15% of people with MS are diagnosed with the primary progressive form of the disease. Until the FDA approval of Ocrevus, there had been no FDA approved treatments for PPMS.
People with all forms of MS experience disease activity – inflammation in the nervous system and permanent loss of nerve cells in the brain – even when their clinical symptoms aren’t apparent or don’t appear to be getting worse. An important goal of treating MS is to reduce disease activity as soon as possible to slow how quickly a person’s disability progresses. Despite available disease-modifying treatments (DMTs), some people with RMS continue to experience disease activity and disability progression.
About Ocrevus® (ocrelizumab)
Ocrevus is the first and only therapy approved for both RMS (including clinically isolated syndrome, RRMS and active, or relapsing, SPMS) and PPMS, with dosing every six months. 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:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| |
|
|
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?
Ocrevus may cause serious side effects, including:
- Risk of cancers (malignancies) including breast cancer. Follow your healthcare provider’s instructions about standard screening guidelines for breast cancer.
Most common side effects include infusion reactions and infections.
These are not all the possible side effects of Ocrevus.
Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

About neuromyelitis optica spectrum disorder
Neuromyelitis optica spectrum disorder (NMOSD) is a rare, lifelong and debilitating autoimmune condition of the central nervous system that primarily damages the optic nerve(s) and spinal cord, causing blindness, muscle weakness and paralysis. People with NMOSD experience unpredictable, severe relapses directly causing cumulative, permanent, neurological damage and disability. In some cases, relapse can result in death. NMOSD affects over 10,000 people in Europe, up to 15,000 people in the United States and approximately 200,000 people worldwide. NMOSD can affect individuals of any age, race and gender, but is most common among women in their 30s and 40s, and appears to occur at higher rates in people of African or Asian background. There is some evidence that people of African or Asian descent may also experience a more severe disease course.
NMOSD is commonly associated with pathogenic antibodies (AQP4) that target and damage a specific cell type, called astrocytes, resulting in inflammatory lesions of the optic nerve(s), spinal cord and brain. AQP4 antibodies are detectable in the blood serum of around 70-80% of NMOSD patients.
Although most cases of NMOSD can be confirmed through diagnostic tests, people living with the condition are still frequently misdiagnosed with multiple sclerosis. This is due to overlapping characteristics of the two disorders, including a higher prevalence in women, similar symptoms and the fact that both are relapse-based conditions.
About Enspryng™ (satralizumab-mwge)
Enspryng, which was designed by Chugai, a member of the Roche Group, is a humanized monoclonal antibody that targets IL-6 receptor activity. The cytokine IL-6 is believed to be a key driver in NMOSD, triggering the inflammation cascade and leading to damage and disability. Enspryng was designed using novel recycling antibody technology, which compared to conventional technology, allows for longer duration of the antibody and subcutaneous dosing every four weeks.
Positive Phase III results for Enspryng, as both monotherapy and used concurrently with baseline immunosuppressant 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 approved in the U.S., Canada, Japan and Switzerland. Applications are under review with numerous regulators, including in the EU and China.
Enspryng has been designated as an orphan drug in the U.S., Europe and Japan. In addition, it was granted Breakthrough Therapy Designation for the treatment of NMOSD by the FDA in December 2018.
What is Enspryng?
Enspryng is a prescription medicine used to treat neuromyelitis optica spectrum disorder (NMOSD) in adults who are aquaporin-4 (AQP4) antibody positive.
It is not known if Enspryng is safe and effective in children.
Important Safety Information
Patients should not take Enspryng if they:
- are allergic to satralizumab-mwge or any of the ingredients in Enspryng
- have an active hepatitis B infection
- have active or untreated inactive (latent) tuberculosis (TB)
Enspryng may cause serious side effects including:
- Infections. Enspryng can increase risk of serious infections some of which can be life-threatening. Patients should speak with their healthcare provider if they are being treated for an infection and call right away if there are signs of an infection, with or without a fever, such as:
- chills, feeling tired, muscle aches, cough that will not go away or a sore throat
- skin redness, swelling, tenderness, pain or sores on the body
- diarrhea, belly pain, or feeling sick
- burning when urinating or urinating more often than usual
A healthcare provider will check for infection and treat it if needed before starting or continuing to take Enspryng
- A healthcare provider should test for hepatitis and TB before initiating Enspryng
- All required vaccinations should be completed before starting Enspryng. People using Enspryng should not be given ‘live’ or ‘live-attenuated’ vaccines. ‘Live’ or ‘live-attenuated’ vaccines should be given at least 4 weeks before a patient starts Enspryng. A healthcare provider may recommend that a patient receive a ‘non-live’ (inactivated) vaccine, such as some of the seasonal flu vaccines. If a patient plans to get a ‘non-live’ (inactivated) vaccine it should be given, whenever possible, at least 2 weeks before starting Enspryng
- Increased liver enzymes. A healthcare provider should order blood tests to check patient liver enzymes before and while taking Enspryng. A healthcare provider will dictate how often these blood tests are needed. Patients should complete all follow-up blood tests as ordered by a healthcare provider. A healthcare provider may wait to start Enspryng if liver enzymes are increased
- Low neutrophil count. Enspryng can cause a decrease in neutrophil counts in the blood. Neutrophils are white blood cells that help the body fight off bacterial infections. A healthcare provider should order blood tests to check neutrophil counts while a patient is taking Enspryng.
- Serious allergic reactions that may be life-threatening have happened with other medicines like Enspryng. Patients should call their healthcare provider right away if they have any of these symptoms of an allergic reaction:
- shortness of breath or trouble breathing
- swelling of lips, face, or tongue
- dizziness or feeling faint
- moderate or severe stomach (abdominal) pain or vomiting
- chest pain
Before taking Enspryng, patients should tell their healthcare provider about all of their medical conditions, including if they:
- have or think they have an infection
- have liver problems
- have ever had hepatitis B or are a carrier of the hepatitis B virus
- have had or have been in contact with someone with TB
- have had a recent vaccination or are scheduled to receive any vaccination
- are pregnant, think they might be pregnant, or plan to become pregnant. It is not known if Enspryng will harm one’s unborn baby
- are breastfeeding or plan to breastfeed. It is not known if Enspryng passes into breast milk. Patients should speak with their healthcare provider about the best way to feed one’s baby while on treatment with Enspryng
Patients should tell their healthcare provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins and herbal supplements.
The most common side effects of Enspryng include:
- sore throat, runny nose (nasopharyngitis)
- headache
- upper respiratory tract infection
- rash
- fatigue
- nausea
- extremity pain
- inflammation of the stomach lining
- joint pain
For more information about the risk and benefit profile of Enspryng, patients should ask their healthcare provider.
Patients may report side effects to the FDA at 1-800-FDA-1088 or http://www.fda.gov/medwatch. Patients may also report side effects to Genentech at 1-888-835-2555.
