Genentech Presents New Ocrevus (Ocrelizumab) Biomarker Data That Increase Understanding of Disease Progression in Multiple Sclerosis at ECTRIMS
Blood neurofilament light chain (NfL) levels were significantly lowered following Ocrevus treatment in analyses of Phase III studies in RMS and PPMS
New data show NfL may be a biomarker for predicting future disability outcomes
Separate analyses presented from one of the first studies to demonstrate NfL levels are correlated with active MRI lesions in PPMS
South San Francisco, CA -- September 9, 2019 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today new data from Ocrevus® (ocrelizumab) trials in relapsing and primary progressive multiple sclerosis (MS). The analyses provide new insights into the biology of MS that advance the understanding of disease progression, with the goal of identifying and slowing disease progression as early as possible to preserve patient function over the long term. Findings will be presented at the 35th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) from September 11 – 13 in Stockholm.
Following Ocrevus treatment, blood neurofilament light chain (NfL) levels were lowered to a healthy donor range1 in relapsing MS (RMS) and primary progressive MS (PPMS) patients. NfL is a protein that provides structural support to nerve fibers in the brain. An increase in the amount of NfL may be associated with nerve cell damage, and detection of increased NfL levels in blood or cerebrospinal fluid (CSF) may serve as a biomarker of nerve cell damage. In the Phase III OPERA I study in RMS and the ORATORIO study in PPMS, blood NfL levels were significantly lower after treatment with Ocrevus. In RMS, blood serum NfL levels were reduced by 43% from baseline to 96 weeks after Ocrevus treatment compared with a 31% reduction with interferon beta-1a (p<0.001). In PPMS, blood plasma NfL levels were reduced by 16% from baseline to 96 weeks after Ocrevus treatment compared with 0.2% reduction with placebo (p<0.001). Additionally, these analyses showed higher blood NfL levels at the start of the study were correlated with more disability progression in upper and lower limbs in PPMS and overall disability in the interferon beta-1a RMS treatment group at 96 weeks.
Few studies have described the relationship between NfL levels and MRI in a well-characterized PPMS patient group. New data from the Phase III OBOE study in PPMS and RMS show that PPMS patients with active MRI lesions (gadolinium-enhancing T1 lesions) had median CSF NfL levels twice as high as those without these lesions. As previously reported, RMS patients with active MRI lesions also had significantly higher NfL levels. Collectively, these data around NfL in MS advance the understanding of it as a potential biomarker of disease progression and may provide insight into the potential neuroprotective effects following Ocrevus treatment.
“These analyses from the Ocrevus trials strengthen the evidence for pursuing neurofilament light chain as a potential biomarker of disease activity and progression in MS, including its potential to predict future disability outcomes,” said Amit Bar-Or, M.D., FRCP, FAAN, FANA, chair of the Scientific Steering Committee of the OBOE study and chief of the Multiple Sclerosis Division of the Department of Neurology at the Perelman School of Medicine, University of Pennsylvania, Philadelphia. “Disease progression in MS can be challenging to identify without noticeable relapses or disability progression, and continued investigation into neurofilament light chain may help us better understand the underlying progression in all forms of this disease.”
Ocrevus is the first and only therapy approved for both RMS (including relapsing-remitting MS (RRMS) and active, or relapsing, secondary progressive MS, in addition to clinically isolated syndrome in the United States) and PPMS. Ocrevus is dosed every six months, with rapidly increasing real-world experience and more than 120,000 people with MS treated globally. Ocrevus is now approved in 89 countries across North America, South America, the Middle East, and Eastern Europe, as well as in Australia, Switzerland and the European Union.

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 percent 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 percent 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.
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.
Ocrevus can cause serious side effects, including:
- Infusion reactions: Ocrevus can cause infusion reactions that can be serious and 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
- coughing or wheezing
- trouble breathing
- throat irritation or pain
- feeling faint
- redness on your face (flushing)
- swelling of the throat
- shortness of breath
- fast heartbeat
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.
- Ocrevus increases your risk of getting upper respiratory tract infections, lower respiratory tract infections, skin infections, and herpes infections. Tell your healthcare provider if you have an infection or have any of the following signs of infection including fever, chills, a cough that does not go away, or signs of herpes (such as cold sores, shingles, or genital sores). These signs can happen during treatment or after you have received your last dose of Ocrevus. If you have an active 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.
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.
- 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.
