MISSISSAUGA, ON and MONTREAL, Dec. 9, 2016 /CNW/ - Health Canada has approved ZINBRYTA™ (daclizumab beta), a new once-monthly, self-administered, subcutaneous treatment for adult patients with active relapsing remitting multiple sclerosis (RRMS), who have had an inadequate response to, or are unable to tolerate, one or more therapies indicated for the treatment of multiple sclerosis, Biogen (NASDAQ: BIIB) and AbbVie (NYSE: ABBV) announced today.
"ZINBRYTA™ is the first once-monthly, self-administered treatment for MS, and it demonstrated superior efficacy over a widely used interferon. Clinical data showed ZINBRYTA™ significantly reduced relapses and brain lesions for up to three years compared to AVONEX® (interferon beta-1a) intramuscular injection, and has a positive benefit-risk profile with monthly patient monitoring," said Lisa Hickey, Vice President and Managing Director at Biogen Canada Inc. "Not only does the Health Canada approval reflect our long-term commitment to our patients, it provides people living with MS a further treatment choice to meet their diverse and evolving needs."
The Health Canada approval of ZINBRYTA™ is based on results from two clinical trials, including DECIDE, the largest and longest head-to-head global Phase 3 clinical trial conducted in MS. The Phase 2b SELECT and Phase 3 DECIDE studies were global, randomized, double-blind, controlled studies that involved approximately 2,400 people living with relapsing MS. Some patients in DECIDE were treated for up to three years.
In DECIDE and SELECT, ZINBRYTA™ significantly reduced the annualized relapse rate (ARR), the primary endpoint of the studies, by 45 percent compared to AVONEX® up to 144 weeks and by 54 percent compared to placebo at 52 weeks (both p<0.0001), respectively.
Results from DECIDE showed that ZINBRYTA™ demonstrated superior efficacy across multiple measures of MS disease activity (relapses and MRI) compared to AVONEX®, including a significant reduction in the mean number of new or newly enlarging T2-hyperintense lesions by 54 percent compared to AVONEX® at 96 weeks (p<0.0001).
The ZINBRYTA™ Product Monograph includes a Serious Warnings and Precautions box for the risk of hepatic injury, including autoimmune hepatitis, and other immune-mediated disorders such as skin reactions, lymphadenopathy, autoimmune hemolytic anemia and gastrointestinal disorders can occur in patients treated with ZINBRYTA™.1 Because of these risks, access to ZINBRYTA™ in Canada is available through a controlled distribution program called Biogen ONE® Support Program. Only prescribers and pharmacies registered with the program are able to prescribe and dispense ZINBRYTA™. In addition, ZINBRYTA™ can only be dispensed to patients who are registered in the Biogen ONE® Support Program. Patients will be informed about the risks of ZINBRYTA™ and how to meet the conditions of the Biogen ONE® Support Program, including compliance with monthly monitoring and assessment of liver enzymes before the next dose of ZINBRYTA™.
"MS affects each person differently, so having additional therapeutic options to address their needs throughout the course of this long term disease is very important news," said Marcelo Kremenchutzky, MD, FRCPC, FAAN, Chapman Chair in MS Clinical Research at London Health Sciences Centre and Associate Professor in Neurology at Western University, London, Ontario. "Daclizumab beta provides a meaningful new option for the treatment of people with MS, with demonstrated efficacy and convenient once-monthly dosing."
ZINBRYTA™ is thought to work differently from other disease-modifying therapies by binding to CD25, a subunit of the interleukin-2 (IL-2) receptor found on activated lymphocytes, cells believed to underlie the biology of MS. Total lymphocyte, T and B cell counts decreased less than 10 percent from baseline during the first year of treatment. The effects on total lymphocyte counts returned to baseline within approximately eight to 12 weeks after the last dose of ZINBRYTA™.
"ZINBRYTA™ has a different target in the immune system compared to other MS therapies," said Dr. Marcelo Kremenchutzky. "ZINBRYTA™ provides both patients and clinicians an additional and distinct treatment option to consider. Having options is critical when the course of MS can be so different from patient to patient."
The most common adverse reactions (incidence at least 1 percent higher incidence than comparator) that occurred in ZINBRYTA™-treated patients were nasopharyngitis (inflammation of the nose and a part of the throat), upper respiratory tract infection, rash, influenza, dermatitis, oropharyngeal (part of the throat) pain, bronchitis, eczema, and lymphadenopathy (enlargement of the lymph nodes) compared with AVONEX®; and upper respiratory tract infection, depression, rash, pharyngitis (inflammation of part of the throat), and increased alanine aminotransferase (ALT; a type of liver enzyme) compared with placebo. The Canadian ZINBRYTA™ Product Monograph also includes warnings and precautions for hepatic injury, immune-mediated disorders, acute hypersensitivity (inflammatory reaction), infections, depression and suicide.1

About the DECIDE StudyDECIDE was a two- to three-year, Phase 3, global, randomized, double-blind, multicenter study in patients with relapsing forms of multiple sclerosis (MS) designed to determine if ZINBRYTA™ would provide superior outcomes for certain clinical endpoints compared to treatment with AVONEX® (interferon beta-1a) 30 mcg intramuscular (IM) injection. DECIDE was an active comparator study with two groups: 150 mg of subcutaneous (SC) ZINBRYTA™ every four weeks (n=919) was compared to AVONEX® IM once weekly (n=922).
About the SELECT StudySELECT was a multicenter, randomized, double-blind, Phase 2b study that evaluated the efficacy and safety of ZINBRYTA™ 150 mg (n=208) and 300 mg (n=209) subcutaneous every four weeks for one year versus placebo (n=204) in patients with relapsing remitting MS.
About ZINBRYTA™ (daclizumab beta)ZINBRYTA™ is being developed globally for relapsing forms of multiple sclerosis (MS). In Canada, ZINBRYTA™ is indicated for the treatment of adult patients with active relapsing remitting multiple sclerosis (RRMS) who have had an inadequate response to, or are unable to tolerate, one or more therapies indicated for the treatment of multiple sclerosis.
The recommended dosage of ZINBRYTA™ is 150 mg, self-administered subcutaneously on a monthly basis. The U.S. Food and Drug Administration (FDA) and European Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA), and the Australian Therapeutic Goods Administration (TGA) recently granted approval for ZINBRYTA™. ZINBRYTA™ is also currently under regulatory review in Switzerland.
In clinical trials, ZINBRYTA™ demonstrated superior efficacy in reduction of annualized relapse rate and certain MRI endpoints, key measures of MS disease activity, compared to AVONEX® (interferon beta-1a) IM injection and placebo.
ZINBRYTA™ is a humanized IgG1 monoclonal antibody that selectively binds to the high-affinity interleukin-2 (IL-2) receptor subunit (CD25). CD25 is expressed at high levels on T-cells that become activated in people with MS.
The Canadian ZINBRYTA™ Product Monograph includes a Serious Warnings and Precautions box for a risk of hepatic injury including autoimmune hepatitis.1 It also includes warnings and precautions for hepatic injury, immune-mediated disorders, acute hypersensitivity, depression and suicide, infections, vaccinations, and monitoring and laboratory tests. The most common adverse reactions (incidence at least 5 percent and at least 2 percent higher incidence than comparator) that occurred in ZINBRYTA™-treated patients were nasopharyngitis, upper respiratory tract infection, rash, influenza, diarrhea oropharyngeal pain, back pain, arthralgia, bronchitis, oral herpes, dizziness, and lymphadenopathy compared with AVONEX®; and upper respiratory tract infection,depression, rash, pharyngitis, and increased alanine aminotransferase (ALT) compared with placebo.
About Multiple SclerosisMultiple sclerosis (MS) is a chronic, often disabling disease that attacks the central nervous system, which is made up of the brain, spinal cord and optic nerves. Symptoms may be mild or severe, ranging from numbness in the limbs to paralysis or loss of vision. The progression, severity and specific symptoms of MS are unpredictable and vary from one person to another.2 MS affects more than 2.3 million people worldwide3 and an estimated 100,000 Canadians.4 Relapsing MS is the most common form of the disease, accounting for 85 percent of cases, and is characterized by clearly defined acute attacks followed by partial or full recovery.5
Patient SupportAs part of the companies' ongoing commitment to people living with MS, extra support will be provided through the Biogen ONE® Support Program to patients being prescribed ZINBRYTA™.
