Biogen (BIIB) Says New Data at ACTRIMS-ECTRIMS Meeting Showcase Safety and Efficacy of its Industry-Leading MS Portfolio

September 11, 2020 8:05 AM

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:

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:

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 across clinical trial use and patients prescribed TECFIDERA. Of these, 6,335 patients (14,241 patient-years) were from clinical trials.8

TECFIDERA is contraindicated in patients with a known hypersensitivity to dimethyl fumarate or any of the excipients of TECFIDERA. Serious side effects include anaphylaxis and angioedema, and cases of progressive multifocal leukoencephalopathy, a rare opportunistic viral infection of the brain which has been associated with death or severe disability, have been seen with TECFIDERA patients in the setting of prolonged lymphopenia although the role of lymphopenia in these cases is uncertain. Other serious side effects include a decrease in mean lymphocyte counts during the first year of treatment, herpes zoster and other serious infections, liver injury and flushing. In clinical trials, the most common adverse events associated with TECFIDERA were flushing, abdominal pain, diarrhea and nausea.

About TYSABRI® (natalizumab)
TYSABRI is a well-established relapsing multiple sclerosis (RMS) treatment indicated for relapsing forms of MS in adults 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 over 213,000 people worldwide have been treated with TYSABRI, with over 835,000 patient-years of experience, based on clinical trials and prescription data.9

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. When initiating and continuing treatment with TYSABRI, physicians should consider whether the expected benefit of TYSABRI is sufficient to offset this risk.

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 PLEGRIDY® (peginterferon beta-1a)
PLEGRIDY is a subcutaneous pegylated interferon dosed once every two weeks for relapsing forms of multiple sclerosis (MS) in adults, the most common form of MS. PLEGRIDY is currently approved in over 60 countries including the U.S., Canada, Australia and Switzerland and across the European Union. Nearly 57,000 people worldwide have been treated with PLEGRIDY, with over 107,000 patient-years of experience, based on prescription data.10 Biogen continues to work toward making PLEGRIDY available in additional countries across the globe.

The efficacy and safety of PLEGRIDY are supported by one of the largest pivotal studies with interferons conducted in people living with relapsing-remitting MS. In clinical studies, PLEGRIDY has been proven to significantly reduce the rate of MS relapses, slow the progression of disability and reduce the number of MS brain lesions while demonstrating a well-characterized safety profile for patients with relapsing forms of MS. Side effects reported include liver problems, including liver failure and increases in liver enzymes; depression or suicidal thoughts; serious allergic reactions; cardiac problems, including congestive heart failure; autoimmune disorders; decreases in white blood cell or platelet counts; and seizures. In clinical trials, the most common adverse events associated with PLEGRIDY were injection site reactions and flu-like symptoms. A list of adverse events can be found in the full PLEGRIDY product labeling for each country where it is approved.

About AVONEX® (interferon beta-1a)
AVONEX is prescribed for relapsing forms of MS and is currently approved in over 90 countries. Over 580,000 people worldwide have been treated with AVONEX, with over 2.6 million patient-years of experience, based on prescription data.11 AVONEX is indicated for the treatment of relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.

Symptoms of depression, suicidal ideation or psychosis, and cases of suicide, have been reported with increased frequency with patients receiving AVONEX. Severe hepatic injury, including cases of hepatic failure has been reported rarely in patients. Rare cases of anaphylaxis have been reported. While beta interferons do not have any known direct cardiac toxicity, cases of congestive heart failure, cardiomyopathy and cardiomyopathy with congestive heart failure have been reported in patients without known predisposition. Decreased peripheral blood counts have been reported from postmarketing experience. Seizures have been reported in patients using AVONEX, including patients with no prior history of seizure. Autoimmune disorders of multiple target organs have been reported. Routine periodic blood chemistry, hematology, liver function and thyroid function tests are recommended.
