"The OCREVUS data shared at AAN show the impact of this targeted B cell therapy on slowing disability progression in MS, and further support the approach of early treatment. In the extension studies, patients who received OCREVUS continuously experienced less disease progression than those who began treatment at a later time point," said Stephen Hauser, MD, chair of the Scientific Steering Committee of the OPERA studies, director of the Weill Institute for Neurosciences and chair of the Department of Neurology at the University of California, San Francisco. "It is encouraging that with up to four years of data, we continue to see a robust effect and a consistent safety profile."
After four years of continuous treatment, the benefits of OCREVUS in reducing underlying disease activity in RMS were sustained, as shown in a platform presentation measuring brain MRI activity through the randomised and open-label extension (OLE) periods of the Phase III studies. Patients who stayed on OCREVUS maintained low numbers of T1 gadolinium-enhancing (T1Gd+) lesions [0.017 to 0.00 T1Gd+ lesions per scan] and new/enlarging T2 (N/ET2) lesions [0.052 to 0.072 N/ET2 lesions per scan] through year two of the OLE phase. Patients who switched from Rebif® (interferon beta-1a) to OCREVUS at the start of the OLE period had a complete silencing of T1Gd+ lesions per scan at one and two years (0.48 to 0.00 T1Gd+ lesions per scan), as well as an 85 and 96 percent decrease in N/ET2 lesions per scan at years one and two, respectively (2.16 to 0.33 and 0.08 N/ET2 lesions per scan).
A second four-year analysis presented in a poster at AAN showed people who stayed on OCREVUS through year two of the OLE period sustained low annualised relapse rates (ARR) and 24-week confirmed disability progression (CDP24). Those who switched from interferon beta-1a to OCREVUS experienced a significant decline in ARR and CDP24 by year one that was maintained through year two.
New cognitive performance data, also shared in a platform presentation, showed OCREVUS reduced the risk of 12- and 24-week confirmed cognitive decline (as defined by confirmed worsening on the Symbol Digital Modalities Test [SDMT] of at least four points) by 38 and 39 percent (p≤0.001 and p=0.002, respectively) during the 96-week period in people with RMS, compared to interferon beta-1a. Cognitive impairment occurs in up to 65 percent of people with multiple sclerosis.(1)
In a separate presentation of pooled OPERA I and OPERA II data, people with RMS at increased risk of progressive disease (as determined by baseline Expanded Disability Status Scale (EDSS) and pyramidal Kurtzke Functional Systems scores of at least four and two points, respectively) and treated with OCREVUS experienced a significant improvement in cognitive function compared with those taking interferon beta-1a through 96 weeks (measured as percent achieving ≥4 point improvement in SDMT; 62.2% vs. 46.5%; p=0.009).
"Preserving cognitive function is an important treatment goal in MS as it relates to information processing, problem solving and focusing in day-to-day life," said Stanley Cohan, MD, Ph.D., Medical Director of Providence Multiple Sclerosis Center, Portland, Oregon. "These data, which show that OCREVUS not only delayed onset of documented cognitive decline, but may also improve cognitive function in people with multiple sclerosis, support a potential role for this therapy in addressing one of the most important, common and challenging realities of multiple sclerosis-induced disability."
Also in a platform presentation, OCREVUS was shown at 12 and 24 weeks to reduce the presence of nerve damage and inflammation biomarkers in spinal fluid (cerebrospinal fluid or CSF), including median concentration of neurofilament light chain (NfL) (week 12: - 24%, week 24: - 47%) and median number of CD19+ B cells (week 12: - 86%, week 24: - 82%), respectively. This interim analysis in RMS patients from the new, Phase III Ocrelizumab Biomarker Outcome Evaluation (OBOE) study adds to the field’s body of evidence around key multiple sclerosis biomarkers, which may be used in future research to more rapidly measure new disease activity and how patients are responding to different therapies.
New safety data presented at AAN representing 3,778 RMS and PPMS patients with 9,474 patient years of exposure to OCREVUS, across all OCREVUS clinical trials, remain consistent with the medicine’s favourable benefit-risk profile. As of April 2018, over 40,000 people have been treated globally with OCREVUS.
OCREVUS is now approved in over 55 countries across North America, South America, the Middle East, Eastern Europe, as well as in Australia, Switzerland and the European Union. Marketing applications are currently under review in more than 20 countries across the world.
