New Roche data at the 2019 AAN Annual Meeting showcase breadth and promise of neuroscience portfolio

  • Risdiplam data from Part 1 of pivotal FIREFISH study show infants with Type 1 spinal muscular atrophy achieve key motor milestones and improved survival after one year of treatment
  • New analyses in relapsing and primary progressive multiple sclerosis suggest that higher OCREVUS (ocrelizumab) exposure and lower B-cell levels are important for control of disability progression
  • Satralizumab significantly reduces the risk of relapse in neuromyelitis optica spectrum disorder in pivotal SAkuraSky study
  • New data in Huntington’s disease support dose selection for Phase III trial and provide insight on mutant huntingtin protein (mHTT) reduction

Roche today announced new data for its approved and investigational medicines for the treatment of neurological conditions will be presented at the 71st American Academy of Neurology (AAN) Annual Meeting from 4-10 May in Philadelphia, PA. Presentations include data from a pivotal study for risdiplam in spinal muscular atrophy (SMA), which has the potential to become the first oral treatment for this community. New research for OCREVUS (ocrelizumab) in relapsing and primary progressive multiple sclerosis shows that its effect on reducing the risk of disability progression is associated with higher exposure and lower B-cell levels. Additional OCREVUS data demonstrate the importance of earlier treatment. New data for investigational medicines in neuromyelitis optica spectrum disorder (NMOSD), Huntington’s disease (HD), Alzheimer’s disease and Duchenne muscular dystrophy will also be shared.

“The great need for therapeutic options in areas of neuroscience such as SMA, HD and NMOSD means that every development is a collective step forward,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We continue to invest in research and partnerships to develop new treatment options for these diseases that severely reduce quality of life. We are pleased to contribute to the greater understanding and clinical progress of neurologic diseases at this year’s AAN Annual Meeting to help make a difference in the lives of people and families impacted by these conditions.”

Spinal Muscular Atrophy (SMA)

New data will be presented for risdiplam, an investigational oral survival motor neuron 2 (SMN2) splicing modifier for SMA, which is designed to increase and sustain SMN protein levels in the central nervous system (CNS) and throughout the body. Platform presentations include one-year data from the dose-finding Part 1 of the pivotal FIREFISH study on key motor milestones, motor function and survival in infants with Type 1 SMA. Updated safety, tolerability and pharmacokinetics / pharmacodynamics (PK/PD) data, as well as an exploratory efficacy analysis from Part 1 of the pivotal SUNFISH study in people aged 2-25 years with SMA Types 2 or 3 will also be presented.

Multiple Sclerosis (MS)

New analyses in relapsing and primary progressive multiple sclerosis suggest that higher OCREVUS exposure and lower B-cell levels are important for control of disability progression. Additionally, new long-term data from the Phase III OPERA and ORATORIO open-label extension trials showed earlier treatment with OCREVUS significantly reduced the risk of permanent disability progression. Updated safety data being presented remain consistent with findings from the controlled Phase III trials, supporting OCREVUS’ favourable benefit-risk profile.

Neuromyelitis Optica Spectrum Disorder (NMOSD)

A subgroup analysis based on AQP4-Ig serostatus from the pivotal phase III SAkuraSky trial investigating satralizumab compared to placebo as add-on to baseline immunosuppressants and/or corticosteroids for the treatment of NMOSD will be presented. The subgroup data shows that satralizumab significantly reduced the risk of NMOSD relapse in a clinically-relevant population, especially in AQP4-Ig positive patients, with a favourable benefit-risk profile. The Phase III trial SAkuraStar, investigating satralizumab compared to placebo as a monotherapy, met its primary endpoint and will be presented at a future congress.

Satralizumab is a humanized IgG2 anti-human interleukin-6 (IL-6) receptor neutralizing monoclonal antibody that represents a novel approach to treating NMOSD by selectively inhibiting the inflammatory effects of IL-6, thought to be a key driver in the pathogenesis of the disease. There are currently no approved treatments for NMOSD, a rare, lifelong and debilitating autoimmune disease of the central nervous system that damages the optic nerve and spinal cord, causing blindness, muscle weakness and paralysis.

Huntington’s Disease (HD)

The HD platform session will include results from a translational modelling approach developed from preclinical data and includes clinical RG6042 data from the ongoing, open label extension study in HD patients, including a safety update and mutant huntingtin (mHTT) protein reduction in the cerebrospinal fluid. These data also support the dose selection for the recently initiated Phase III GENERATION HD1 clinical trial investigating RG6042 in manifest Huntington’s disease.

RG6042 (formerly known as Ionis HTT-Rx) is an antisense oligonucleotide (ASO) designed to reduce the production of the toxic mHTT protein, the disease-causing protein in people with Huntington’s disease, by targeting human huntingtin RNA.

Alzheimer’s disease (AD)

Data and safety findings from the gantenerumab SCarlet RoAD and Marguerite RoAD open-label extension studies will be presented that show consistently large amyloid reductions in AD patients with and without ARIA-E. Roche continues to advance the development of gantenerumab in the Phase III GRADUATE trials and the anti-tau molecule RO7105705 (MTAU9937A, RG6100) into its second Phase II clinical trial (LAURIET), which is currently enrolling patients with moderate Alzheimer’s disease.

The study design, methodology and baseline characteristics from the crenezumab Phase III CREAD study will be presented in a poster at AAN. Data from the crenezumab interim analysis of the now discontinued CREAD program were presented at the 14th International Conference on Alzheimer’s & Parkinson’s Diseases in March 2019. Additional analyses, including biomarker data, will be presented at future medical conferences. Crenezumab continues to be studied in a landmark Alzheimer’s Prevention Initiative trial of cognitively healthy individuals in Colombia with an autosomal dominant mutation who are at risk to develop familial AD (fAD).

Duchenne Muscular Dystrophy (DMD)

Results will be shared from a Phase Ib/II study of the anti-myostatin adnectin RG6206 in ambulatory boys with DMD showing no drug-related safety findings leading to withdrawal from the study through 72 weeks of treatment. RG6042 successfully lowered myostatin levels in the blood of boys with DMD and MRI and DXA imaging suggested that RG6206 had a positive effect on muscle in boys with DMD.

The full range of data from Roche’s late-stage clinical development program in neuroscience being presented at AAN include:
