− Data Confirm ZINBRYTA™ is Superior to AVONEX® in Reducing Annualized Relapse Rate –
− First Presentation of Full DECIDE Results at ACTRIMS-ECTRIMS Meeting –
CAMBRIDGE, Mass. & NORTH CHICAGO, Ill.--(BUSINESS WIRE)--Today Biogen Idec (NASDAQ: BIIB) and AbbVie (NYSE: ABBV) announced the full results from the Phase 3 DECIDE clinical trial, which show ZINBRYTA™ (daclizumab high-yield process), dosed subcutaneously once a month, demonstrated a statistically significant improvement in reducing disease activity in people with relapsing-remitting multiple sclerosis (RRMS) compared to AVONEX® (interferon beta-1a).
These results are being presented at the Sixth Triennial 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) in Boston.
“The full results from DECIDE demonstrate that ZINBRYTA significantly improved key measures of multiple sclerosis disease activity compared to AVONEX, including reducing annualized relapse rate and new brain lesion development,” said Ludwig Kappos, M.D., chair, Department of Neurology and head, MS-Research Group, University Hospital, Basel, Switzerland, and lead investigator for DECIDE. “These results help us better understand ZINBRYTA as a potential treatment option for people with relapsing-remitting MS.”
DECIDE Detailed Efficacy Results
DECIDE was a two- to three-year, Phase 3, global, randomized, double-blind study that evaluated whether ZINBRYTA would provide superior outcomes for certain clinical endpoints compared to AVONEX. The study enrolled more than 1,800 patients with RRMS.
“For people living with multiple sclerosis, there continues to be a need for new medicines that work in different ways,” said Gilmore O’Neill, vice president, Multiple Sclerosis Research and Development, Biogen Idec. “If approved, ZINBRYTA would offer a novel mechanism to treating MS, in a self-administered, once-monthly dosing regimen.”
DECIDE Safety Results
The safety profile of ZINBRYTA in the DECIDE study was generally consistent with the Phase 2 studies. The overall incidence of adverse events was comparable across the ZINBRYTA and AVONEX treatment groups.
In patients treated with ZINBRYTA compared to AVONEX, there was an increased incidence of serious infections (4 percent vs. 2 percent). The pattern and types of infections seen in the ZINBRYTA group were consistent with what has been previously observed in the MS population.
Also consistent with previous studies, patients in the ZINBRYTA group had a greater incidence of cutaneous adverse events (37 percent vs. 19 percent) and serious cutaneous reactions (2 percent vs. < 1 percent); and elevations of liver transaminases greater than five times the upper limit of normal (6 percent vs. 3 percent). There were four deaths in the AVONEX group and one death in the ZINBRYTA group, none of which was considered treatment related.
Based on the efficacy and safety data from the ZINBRYTA clinical development program, Biogen Idec and AbbVie plan to file marketing applications for ZINBRYTA with regulatory authorities during the first half of 2015.
“The results from DECIDE further support the potential of ZINBRYTA and we look forward to submitting the data for this investigational therapy to regulatory agencies,” said Michael Severino, M.D., executive vice president, Research and Development and chief scientific officer, AbbVie.

Additional ZINBRYTA data were presented:
DECIDE was a two- to three-year, Phase 3, global, randomized, double-blind, multicenter study designed to determine if ZINBRYTA would provide superior outcomes for certain clinical endpoints compared to treatment with AVONEX. The study enrolled more than 1,800 patients with RRMS in 28 countries. DECIDE was an active comparator study with two groups: 150 mg of subcutaneous ZINBRYTA every four weeks was compared to AVONEX 30 mcg intramuscular injection once weekly.
The primary endpoint in DECIDE was the reduction in ARR. Secondary endpoints included the number of new or newly enlarging T2-hyperintense lesions, the proportion of patients with sustained disability progression (EDSS), the proportion of relapse-free patients and the proportion of patients who experienced a worsening physical impact score on the Multiple Sclerosis Impact Scale (MSIS-29). Secondary endpoints were rank ordered and tested with a sequential closed testing procedure to control inflation of type I error due to multiple endpoints. If a comparison was not statistically significant, then all endpoints of a lower rank were not significant per the closed testing procedure.
After completing the DECIDE study, patients have the option to participate in an open-label extension study called EXTEND.
The ZINBRYTA development program also includes the previously completed pivotal, placebo-controlled, double-blind SELECT study.
About ZINBRYTA™ (daclizumab high-yield process)
ZINBRYTA (daclizumab high-yield process) is an investigational drug and is a new form of a humanized monoclonal antibody that selectively binds to the high-affinity interleukin-2 (IL-2) receptor subunit (CD25) that is expressed at high levels on T-cells that become abnormally activated in MS. ZINBRYTA modulates IL-2 signaling without causing general immune cell depletion. ZINBRYTA is believed to work by decreasing abnormally-activated T-cells and pro-inflammatory lymphoid tissue inducer cells, and increasing CD56bright natural killer (NK) cells, important cells that help regulate the immune system.
Biogen Idec and AbbVie are jointly developing ZINBRYTA.
About AVONEX® (interferon beta-1a)
AVONEX is one of the most prescribed treatments for relapsing forms of MS worldwide. AVONEX is indicated for the treatment of patients with relapsing forms of MS to slow the accumulation of physical disability and decrease the frequency of clinical exacerbations. Patients with MS in whom efficacy has been demonstrated include patients who have experienced a first clinical episode and have MRI features consistent with MS. 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 post-marketing 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. AVONEX should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. The most common side effects associated with AVONEX treatment are flu-like symptoms, including chills, fever, myalgia, and asthenia.
