New Data at ACTRIMS-ECTRIMS Meeting Showcase Safety and Efficacy of Biogen’s Industry-Leading MS Portfolio

  • New data from ongoing Phase 3 study further define the effectiveness and improved GI tolerability of VUMERITY® (diroximel fumarate)
  • Real-world findings evaluate quality of life benefits associated with TYSABRI® (natalizumab) when compared to Ocrevus®(ocrelizumab)
  • Additional real-world findings report positive benefits of PLEGRIDY® (peginterferon beta-1a) and AVONEX® (interferon beta-1a) in older individuals with relapsing multiple sclerosis

CAMBRIDGE, Mass., Sept. 11, 2020 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) today announced new data underscoring the efficacy and safety of its broad, industry-leading portfolio of multiple sclerosis (MS) therapies. These data will be presented during MSVirtual2020, the eighth joint meeting of the Americas Committee for Treatment and Research in Multiple Sclerosis and the European Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS-ECTRIMS), which will be held virtually September 11-13, 2020.

“We at Biogen are proud of our commitment to addressing both the urgent and long-term challenges facing people living with MS,” said Maha Radhakrishnan, M.D., Chief Medical Officer at Biogen. “The data we are presenting at ACTRIMS-ECTRIMS highlight the improved outcomes that our broad MS portfolio has continued to provide for people with relapsing forms of MS, regardless of where they are in their treatment journey, as well as our ongoing investment in research and development to identify potentially effective drug candidates.”

New Phase 3 Data Further Characterize the Effectiveness and Patient-Reported GI Tolerability of VUMERITY® (diroximel fumarate)
New data from the VUMERITY Phase 3 clinical program further define the effectiveness and safety profile of Biogen’s latest oral fumarate therapy. Findings from the five-week EVOLVE-MS-2 study reinforce clinically meaningful improvements in patient-assessed gastrointestinal (GI) tolerability associated with VUMERITY treatment (n=253) compared to TECFIDERA® (dimethyl fumarate) (n=251), and support its impact on quality of life for people with relapsing MS. Study participants taking VUMERITY reported a lower likelihood of experiencing GI symptoms that interfered with daily activities or were associated with missed work, as well as less concomitant medication use to treat GI symptoms.

An exploratory analysis from the ongoing EVOLVE-MS-1 study assessed the effects of VUMERITY on brain volume change and other clinical measures in people with relapsing MS (n=365) treated for up to two years. Separate studies have shown brain volume loss may be associated with cognitive impairment, physical disability and reduced quality of life in people with MS.1,2 Data from EVOLVE-MS-1 show:

  • The annual rate of brain volume change in study participants treated with VUMERITY for two years was similar to the rate observed in healthy individuals; and
  • Approximately 90 percent of people treated with VUMERITY remained free from confirmed disability progression and around 84 percent were relapse-free at two years.

Also being presented at the meeting are final data from the Phase 3 ENDORSE study, which further demonstrate the sustained efficacy and well-characterized safety profile of TECFIDERA in patients followed for up to 13 years.

Real-World Data From Separate Analyses in the Relapsing MS Population Show Improved Outcomes With TYSABRI® (natalizumab), PLEGRIDY® (peginterferon beta-1a) and AVONEX® (interferon beta-1a)
Through MS PATHS (Partners Advancing Technology and Health Solutions), Biogen is collaborating with leading MS centers in Europe and the U.S. to generate standardized, high-quality data from a diverse, real-world MS patient population. To date, more than 17,000 patients have been enrolled in MS PATHS. Data being presented from treatment in the real-world setting support improved outcomes associated with TYSABRI, PLEGRIDY and AVONEX. Results from separate analyses of MS PATHS data reveal the following:

  • In the first comparison of MS PATHS standardized magnetic resonance imaging (MRI) protocols, analyses of changes in brain MRI (occurring over a mean follow-up of 0.8 years) were compared during natalizumab treatment with extended interval dosing (EID; n=85) to the approved every-four-week (Q4W; n=569) dosing. The analysis reported no significant differences in the rates of new T2 lesions, T2 lesion volumes and brain atrophy. Differences in MRI scanners and acquisition protocols in clinical practice have made comparisons of brain MRI outcomes challenging. Multiple real-world studies have suggested the effectiveness of natalizumab EID is similar to the approved Q4W dosing.3-7 Biogen continues to evaluate the efficacy, safety and tolerability of natalizumab EID through the prospective NOVA trial (NCT03689972), and recently filed with regulatory authorities for a subcutaneous dosing formulation which, if approved, would allow for more options for TYSABRI administration.
  • Treatment with TYSABRI was associated with greater improvements than Ocrevus® (ocrelizumab) in several quality of life domains according to the Neuro-QoL (Quality of Life in Neurological Disorders) assessment. In a subgroup analysis of matched patients treated with TYSABRI or Ocrevus, significant improvement was observed in nine of 12 Neuro-QoL domains in patients treated with TYSABRI (n=144) and in four of 12 domains in patients treated with Ocrevus (n=502). Overall, annualized rates of improvement were higher with TYSABRI than with Ocrevus and significant differences were observed in three domains: positive affect and well-being, satisfaction with social roles and activities and sleep disturbance. 
  • Clinical outcomes in people with MS aged 60 or older (n=286), compared to those under 60 (n=729), indicate that PLEGRIDY and AVONEX may provide real-world treatment benefits over two years in both age groups. Data show functional improvements in processing speed test (PST) and contrast sensitivity test (CST) over one year in both age groups. Additionally, a majority of participants in both age groups remained free from relapse over two years.

Data From a Phase 1 Study of BIIB091 Supports Continued Development for the Treatment of MS
Biogen also presented data from a Phase 1 study of BIIB091, an orally active selective, reversible (noncovalent), small molecule inhibitor of Bruton’s Tyrosine Kinase (BTK). Data evaluated the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple ascending oral doses in healthy adult participants. Selective BTK inhibition may be beneficial for the treatment of MS by preventing B-cell and myeloid cell activation without immune cell depletion.

About VUMERITY® (diroximel fumarate)
VUMERITY is an oral fumarate with a distinct chemical structure from TECFIDERA® (dimethyl fumarate), approved in the U.S. for the treatment of relapsing forms of multiple sclerosis in adults, to include clinically isolated syndrome, relapsing-remitting disease and active secondary progressive disease. Once in the body, VUMERITY rapidly converts to monomethyl fumarate, the same active metabolite of dimethyl fumarate.

VUMERITY is contraindicated in patients with known hypersensitivity to diroximel fumarate, dimethyl fumarate or any of the excipients of VUMERITY; and in patients taking dimethyl fumarate. Serious side effects for VUMERITY are based on data from dimethyl fumarate (which has the same active metabolite as VUMERITY) and include anaphylaxis and angioedema, progressive multifocal leukoencephalopathy, which is a rare opportunistic viral infection of the brain that has been associated with death or severe disability, a decrease in mean lymphocyte counts during the first year of treatment, herpes zoster and other serious infections, liver injury and flushing. The most common adverse events, obtained using data from dimethyl fumarate (which has the same active metabolite as VUMERITY), were flushing, abdominal pain, diarrhea and nausea.

About TECFIDERA® (dimethyl fumarate) 
TECFIDERA, a treatment for relapsing forms of multiple sclerosis (MS) in adults, is the most prescribed oral medication for relapsing MS in the world and has been shown to reduce the rate of MS relapses, slow the progression of disability and impact the number of MS brain lesions, while demonstrating a well-characterized safety profile in people with relapsing forms of MS. TECFIDERA is approved in 69 countries, and more than 475,000 patients have been treated with it, representing more than 950,000 patient-years of exposure...
