Roche to present pivotal data for satralizumab in neuromyelitis optica spectrum disorder and six-year OCREVUS data in multiple sclerosis at ECTRIMS

• Investigational medicine satralizumab significantly reduces the risk of relapse in pivotal SAkuraStar monotherapy study for neuromyelitis optica spectrum disorder
• New data provide insights into neurofilament light chain levels as a potential biomarker for predicting MS disability progression; new longer-term OCREVUS® (ocrelizumab) data of more than six years show reduction of disability progression in relapsing and primary progressive MS
• Breadth of data reinforce Roche's commitment to following the science to gain a better understanding of complex nervous system disorders
  
  

Basel, 4 September 2019 – Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that new data across its neuroscience portfolio will be presented at the 35th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) from 11-13 September in Stockholm, Sweden. Presentations include complete Phase III results from the SAkuraStar study investigating satralizumab for the treatment of neuromyelitis optica spectrum disorder (NMOSD), and new multiple sclerosis (MS) research, which provides insights into disease progression, including data from OCREVUS® (ocrelizumab) trials that advance understanding of neurofilament light chain (NfL) levels as a potential biomarker for predicting disability outcomes. Additionally, longer-term data of more than six years to be presented continue to show consistent safety and efficacy outcomes for patients treated with OCREVUS earlier.

“Disorders of the nervous system are some of the most complex and difficult to treat, and we have increased our commitment in neuroscience to advance care and scientific understanding for conditions such as multiple sclerosis and neuromyelitis optica spectrum disorder. Data being presented at ECTRIMS include positive Phase III results for satralizumab as a monotherapy, taking a novel approach to treating neuromyelitis optica spectrum disorder, and new insights using biomarkers to identify disease progression in multiple sclerosis,” said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. “Similar to our approach with OCREVUS in multiple sclerosis, targeting B-cells as a key driver of disease, we aim to offer satralizumab as a highly effective treatment option in neuromyelitis optica spectrum disorder, targeting the interleukin-6 receptor.”

Neuromyelitis Optica Spectrum Disorder (NMOSD)
Complete pivotal data from the SAkuraStar study investigating satralizumab as a subcutaneous monotherapy compared to placebo for the treatment of NMOSD will be presented. The primary and subgroup analyses show that satralizumab significantly reduces the risk of relapse in patients who were seropositive for aquaporin-4 auto-antibodies (AQP4-IgG), as well as the overall ITT population representative of NMOSD patients. Satralizumab also demonstrates a similar safety profile compared to placebo.

NMOSD is a rare, lifelong and debilitating autoimmune disease of the central nervous system commonly misdiagnosed as MS. It is associated with pathogenic auto-antibodies (AQP4-IgG) that target and damage a specific cell type, called astrocytes, resulting in inflammatory lesions of the optic nerve(s), spinal cord and brain. Through the use of a diagnostic biomarker test, the majority of people with NMOSD are identified as AQP4-IgG seropositive and tend to experience a more severe disease course; however, as many as one-third of those with NMOSD are AQP4-IgG seronegative. At ECTRIMS, two analyses of U.S. healthcare insurance claims databases will be presented that reflect the low utilisation of AQP4-IgG diagnostic testing and the subsequent frequency of misdiagnosis of NMOSD patients.

Additionally, two pre-clinical in-vitro models will be presented that show satralizumab reduces the degradation of the blood brain barrier, supporting evidence of its multi-faceted mechanism of action.

Multiple Sclerosis (MS)
New analyses will be presented that advance understanding of NfL as a potential biomarker for predicting future MS disability outcomes, including data from the Phase III studies showing blood NfL levels in primary progressive MS (PPMS) and relapsing MS (RMS) patients were significantly lowered following OCREVUS treatment. NfL is a protein that provides structural support to nerve fibres in the brain, and an increase in the amount of NfL in blood serum or cerebrospinal fluid may serve as a marker for axonal (nerve) damage. Studying NfL may provide more information on how to quickly measure MS disease activity and progression. This is important because a key goal of treatment is to reduce disease activity to delay disability progression as soon as possible.

Longer-term data of more than six years from the Phase III open-label extension studies of OPERA I, OPERA II and ORATORIO showed that patients who were treated earlier with OCREVUS had lower rates of disability progression compared with RMS patients who switched from interferon beta-1α or PPMS patients who switched from placebo after the double-blind phase. Additionally, updated safety data being presented remain consistent with findings from the Phase III studies, supporting OCREVUS’ favourable benefit-risk profile.

Over 120,000 people have been treated with OCREVUS globally, both in clinical trial and real-world settings, and OCREVUS is now approved in 89 countries.

About satralizumab
Satralizumab is an investigational humanised monoclonal antibody that represents a novel approach to treating NMOSD. The cytokine IL-6 is thought to be a key driver of NMOSD, triggering the inflammation cascade and leading to damage and disability. Positive Phase III results for satralizumab, as both monotherapy and add-on to baseline immunosuppressant therapy, suggest that IL-6 inhibition may be an effective therapeutic approach for NMOSD.

The Phase III clinical development programme for satralizumab includes two studies: SAkuraSky, which studied satralizumab in combination with baseline immunosuppressant therapy, and SAkuraStar, which studied the efficacy and safety of satralizumab as a monotherapy.

Satralizumab has been designated as an orphan drug in the U.S. and Europe. In addition, it was granted Breakthrough Therapy Designation for the treatment of NMO and NMOSD by the U.S. Food and Drug Administration in December 2018.

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 multiple sclerosis (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.
