CAMBRIDGE, Mass., May 01, 2019 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) today announced it will present new data across its industry-leading neuroscience portfolio and advancing clinical development programs at the 71st annual meeting of the American Academy of Neurology (AAN) in Philadelphia, PA. (May 4–11). Of Biogen’s 33 total presentations, key data will focus on spinal muscular atrophy (SMA), multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS).
“Biogen stands at the forefront of neuroscience, taking on some of the most challenging diseases in history as part of our steadfast commitment to supporting patients with a range of complex and rare neurological disorders,” said Alfred Sandrock, Jr., M.D., Ph.D., executive vice president and chief medical officer at Biogen. “Our data at AAN illustrate our drive to advance critical research for people who have limited or no treatment options.”
Research across Biogen’s clinical and development programs demonstrates the company’s commitment to further understanding neurodegenerative diseases with unmet need. SMA and MS data focus on validating biomarkers that aid in monitoring and detecting disease progression, while pipeline data underscore the company’s emphasis on thoughtful study design and understanding the patient journey.
SMA Data Presentations Reinforce SPINRAZA as Standard of Care in Treating SMA, Underscoring Therapy’s Long-Term Benefit for Infants, Children and Adults
- Results from the NURTURE study demonstrate that pre-symptomatic infants with SMA treated with SPINRAZA over three years achieved motor milestones more consistent with normal childhood development.
- After three years of follow-up, interim results from the ENDEAR/CHERISH/SHINE open-label extension study show that treatment with SPINRAZA, particularly when initiated earlier, leads to progressive motor milestone improvements and increased survival rates for individuals with infantile-onset SMA.
- Additional data suggest that phosphorylated neurofilament heavy chain (pNF-H) may emerge as a promising biomarker to predict disease activity in SMA.
Advancing Biogen’s Pipeline of Investigational Treatments for Neurodegenerative Diseases
- In a late-breaking presentation, Biogen will share expanded findings from its phase 1/2 study of tofersen (BIIB067) for the investigational treatment of ALS with a confirmed SOD1 mutation. Positive interim results of the study, as well as Biogen’s decision to exercise its option to obtain a license from Ionis Pharmaceuticals Inc. to develop and commercialize the asset, were announced in December 2018. Biogen has advanced the program to the ongoing phase 3 clinical study (VALOR), which is a continuation of the Phase 1/2 study. Biogen is collaborating with regulators to further define the scope of the clinical data package required to support the registration of BIIB067.
- Other pipeline data to be presented advance the scientific community’s understanding of rare neurodegenerative diseases, including progressive supranuclear palsy (PSP), and provide updates on Biogen’s investigational programs for stroke and neuropathic pain.
Advancing Biogen’s Portfolio of Leading MS Therapies
- Safety and exploratory efficacy results from the ongoing pivotal EVOLVE-MS-1 study with diroximel fumarate (BIIB098) will be shared, which support the potential of Biogen and Alkermes’ investigational oral treatment as a new option for patients with relapsing MS. If approved, diroximel fumarate will be marketed under the brand name VUMERITY™, which has been conditionally accepted by the FDA and will be confirmed upon approval.
- Committed to improving patient care and further understanding the benefit-risk profile of TYSABRI® (natalizumab), Biogen will present updated safety analyses evaluating extended interval dosing of natalizumab (of approximately every 6 weeks) compared to every 4-week dosing.
- Biogen continues to engage in collaborative research efforts to identify potential biomarkers in MS, and will present results further confirming serum neurofilament light (sNfL) as a clinically useful tool for disease prognosis and treatment management.

About SPINRAZA® (nusinersen)1-4
SPINRAZA is the first and only approved medicine for the treatment of spinal muscular atrophy (SMA) and is currently available in more than 40 countries. As of March 31, 2019 over 7,500 individuals with SMA are being treated with SPINRAZA worldwide, based on patients across the post-marketing setting, Expanded Access Program (EAP) and clinical trial participants.
SPINRAZA is an antisense oligonucleotide (ASO) developed using Ionis’ proprietary antisense technology that is designed to treat the root cause of SMA. SPINRAZA alters the splicing of SMN2 pre-mRNA in order to increase production of full-length SMN protein. ASOs are short synthetic strings of nucleotides designed to selectively bind to target RNA and regulate gene expression. Through use of this technology, SPINRAZA has been shown to increase the amount of full-length SMN protein in individuals with SMA. SPINRAZA is administered via intrathecal injection, which delivers therapies directly into the cerebrospinal fluid (CSF) around the spinal cord, where motor neurons degenerate in individuals with SMA due to insufficient levels of SMN protein.
In the clinical trial program, SPINRAZA demonstrated a favorable benefit-risk profile. The most common adverse reactions that occurred in the SPINRAZA group were respiratory infection and constipation. Serious adverse reactions of atelectasis were more frequent in SPINRAZA-treated patients. Coagulation abnormalities and thrombocytopenia, including acute severe thrombocytopenia, have been observed after administration of some ASOs. Individuals may be at increased risk of bleeding complications. Renal toxicity has been observed after administration of some ASOs. SPINRAZA is present in and excreted by the kidney.
Biogen licensed the global rights to develop, manufacture and commercialize SPINRAZA from Ionis Pharmaceuticals, Inc. (Nasdaq: IONS), a leader in antisense therapeutics. Biogen and Ionis conducted an innovative clinical development program, the largest of its kind in SMA, that moved SPINRAZA from its first dose in humans in 2011 to its first regulatory approval in five years.
TYSABRI is a well-established relapsing multiple sclerosis (RMS) treatment that has been proven in clinical trials to slow physical disability progression, reduce the formation of new brain lesions and cut relapses. TYSABRI is approved in 80 countries, and nearly 200,000 people worldwide have been treated with TYSABRI, with over 725,000 patient-years of experience, based on clinical trials and prescription data.5 In the U.S., TYSABRI is indicated as monotherapy for the treatment of patients with relapsing forms of MS. In the European Union, it is indicated as single disease modifying therapy (DMT) in adults with highly active relapsing-remitting MS (RRMS) for patients despite a full and adequate course of treatment, with at least one DMT or patients with rapidly evolving severe RRMS.
TYSABRI increases the risk of progressive multifocal leukoencephalopathy (PML), a rare opportunistic viral infection of the brain which has been associated with death or severe disability. Risk factors that increase the risk of PML are the presence of anti-JC virus antibodies, prior immunosuppressant use and longer TYSABRI treatment duration. Patients who have all three risk factors have the highest risk of developing PML.
TYSABRI also increases the risk of developing encephalitis and meningitis caused by herpes simplex and varicella zoster viruses, and serious, life-threatening and sometimes fatal cases have been reported in the post-marketing setting in MS patients receiving TYSABRI. Clinically significant liver injury, including acute liver failure requiring transplant, has also been reported in the post-marketing setting. Other serious adverse events that have occurred in TYSABRI-treated patients include hypersensitivity reactions (e.g., anaphylaxis) and infections, including opportunistic and other atypical infections.

About Diroximel Fumarate
Diroximel fumarate (BIIB098) is a novel oral fumarate candidate in development for the treatment of relapsing forms of MS. Diroximel fumarate is designed to rapidly convert to monomethyl fumarate in the body and with a distinct chemical structure, may have the potential to offer differentiated gastrointestinal (GI) tolerability as compared to dimethyl fumarate. Alkermes is conducting the EVOLVE-MS-2 study in patients with relapsing-remitting (RRMS), a five-week, head-to-head study versus dimethyl fumarate to evaluate GI tolerability in addition to the EVOLVE-MS-1 study. Diroximel fumarate is currently under review with the U.S. Food and Drug Administration (FDA) with a PDUFA (Prescription Drug User Fee Act) target action date in the fourth quarter of 2019. Diroximel fumarate will be marketed under the brand name VUMERITY, which has been conditionally accepted by the FDA and will be confirmed upon approval.
Tofersen is an antisense oligonucleotide (ASO) RNase H-mediated inhibitor of SOD1 messenger ribonucleic acid (mRNA) being developed for the treatment of ALS with SOD1 mutations. Tofersen binds to SOD1 mRNA, allowing its degradation by RNase-H and reducing protein production. This is thought to decrease the toxicity of mutant SOD1 and potentially provide therapeutic benefit through improved survival and function to people with ALS with SOD1 mutations. Tofersen demonstrated proof-of-biology and proof-of-concept in a Phase 1 analysis. Biogen licensed tofersen from Ionis Pharmaceuticals, Inc. under a collaborative development and license agreement.
