  • new analysis of larger dataset showed that aducanumab reduced clinical decline in patients with early alzheimer’s disease as measured by the pre-specified primary and secondary endpoints
  • based on discussions with the fda, the company plans to submit a biologics license application in early 2020
  • biogen aims to offer aducanumab to eligible patients previously enrolled in clinical studies 
  • the positive results of this new analysis were driven primarily by greater exposure to high dose aducanumab in the larger dataset as compared to data available at the time of the futility analysis 

cambridge, mass. and tokyo, japan – october 22, 2019 – biogen (nasdaq: biib) and eisai, co., ltd. (tokyo, japan) today announced that, after consulting with the u.s. food and drug administration (fda), biogen plans to pursue regulatory approval for aducanumab, an investigational treatment for early alzheimer’s disease (ad). the phase 3 emerge study met its primary endpoint showing a significant reduction in clinical decline, and biogen believes that results from a subset of patients in the phase 3 engage study who received sufficient exposure to high dose aducanumab support the findings from emerge. patients who received aducanumab experienced significant benefits on measures of cognition and function such as memory, orientation, and language. patients also experienced benefits on activities of daily living including conducting personal finances, performing household chores such as cleaning, shopping, and doing laundry, and independently traveling out of the home. if approved, aducanumab would become the first therapy to reduce the clinical decline of alzheimer’s disease and would also be the first therapy to demonstrate that removing amyloid beta resulted in better clinical outcomes.

the decision to file is based on a new analysis, conducted by biogen in consultation with the fda, of a larger dataset from the phase 3 clinical studies that were discontinued in march 2019 following a futility analysis. this new analysis of a larger dataset that includes additional data that became available after the pre-specified futility analysis shows that aducanumab is pharmacologically and clinically active as determined by dose-dependent effects in reducing brain amyloid and in reducing clinical decline as assessed by the pre-specified primary endpoint clinical dementia rating-sum of boxes (cdr-sb). in both studies, the safety and tolerability profile of aducanumab was consistent with prior studies of aducanumab.

“with such a devastating disease that affects tens of millions worldwide, today’s announcement is truly heartening in the fight against alzheimer’s. this is the result of groundbreaking research and is a testament to biogen’s steadfast determination to follow the science and do the right thing for patients,” said michel vounatsos, chief executive officer at biogen. “we are hopeful about the prospect of offering patients the first therapy to reduce the clinical decline of alzheimer’s disease and the potential implication of these results for similar approaches targeting amyloid beta.”

based on discussions with the fda, the company plans to file a biologics license application (bla) in early 2020 and will continue dialogue with regulatory authorities in international markets including europe and japan. the bla submission will include data from the phase 1/1b studies as well as the complete set of data from the phase 3 studies.

the company aims to offer access to aducanumab to eligible patients previously enrolled in the phase 3 studies, the long-term extension study for the phase 1b prime study, and the evolve safety study. biogen will work towards this goal with regulatory authorities and principal investigators with a sense of urgency.

study results

emerge (1,638 patients) and engage (1,647 patients) were phase 3 multicenter, randomized, double-blind, placebo-controlled, parallel-group studies designed to evaluate the efficacy and safety of two dosing regimens of aducanumab. these studies were discontinued on march 21, 2019, following the results of a pre-specified futility analysis which relied on an earlier and smaller dataset. the futility analysis was based on data available as of december 26, 2018, from 1,748 patients who had the opportunity to complete the 18-month study period and predicted that both studies were unlikely to meet their primary endpoint upon completion. futility analyses are common in large clinical studies and use statistical modeling to attempt to predict the outcome of the studies based on a number of pre-specified assumptions and criteria.

following the discontinuation of emerge and engage, additional data from these studies became available resulting in a larger dataset, which included a total of 3,285 patients, 2,066 of whom had the opportunity to complete the full 18 months of treatment. a new extensive analysis of this larger dataset showed a different outcome than the outcome predicted by the futility analysis. specifically, the new analysis of this larger dataset showed emerge to be statistically significant on the pre-specified primary endpoint (p=0.01). biogen believes that data from a subset of engage support the findings from emerge, though engage did not meet its primary endpoint. biogen consulted with external advisors and the fda on these different results and their implications.

“this large dataset represents the first time a phase 3 study has demonstrated that clearance of aggregated amyloid beta can reduce the clinical decline of alzheimer’s disease, providing new hope for the medical community, the patients, and their families,” said dr. anton porsteinsson, william b. and sheila konar professor of psychiatry, neurology and neuroscience, director of the university of rochester alzheimer’s disease care, research and education program (ad-care), and principal investigator. “there is tremendous unmet medical need, and the alzheimer’s disease community has been waiting for this moment. i commend biogen, the fda, the medical community, and the patients and their study partners for their persistence in working to make today’s announcement a reality.”

in emerge, which met its pre-specified primary endpoint in the new analysis, patients treated with high dose aducanumab showed a significant reduction of clinical decline from baseline in cdr-sb scores at 78 weeks (23% versus placebo, p=0.01). in emerge, patients treated with high dose aducanumab also showed a consistent reduction of clinical decline as measured by the pre-specified secondary endpoints: the mini-mental state examination (mmse; 15% versus placebo, p=0.06), the ad assessment scale-cognitive subscale 13 items (adas-cog 13; 27% versus placebo, p=0.01), and the ad cooperative study-activities of daily living inventory mild cognitive impairment version (adcs-adl-mci; 40% versus placebo, p=0.001). imaging of amyloid plaque deposition in emerge demonstrated that amyloid plaque burden was reduced with low and high dose aducanumab compared to placebo at 26 and 78 weeks (p<0.001). additional biomarker data of tau levels in the cerebrospinal fluid supported these clinical findings. biogen believes that data from patients in engage who achieved sufficient exposure to high dose aducanumab supported the findings of emerge.

in both studies, the most commonly reported adverse events were amyloid-related imaging abnormalities-edema (aria-e) and headache. the majority of patients with aria-e did not experience symptoms during the aria-e episode, and aria-e episodes generally resolved within 4 to 16 weeks, typically without long-term clinical sequelae. biogen plans to present further detail on the new analysis of the larger dataset from emerge and engage at the clinical trials on alzheimer’s disease (ctad) meeting in december 2019.

after reviewing the data in consultation with the fda, biogen believes that the difference between the results of the new analysis of the larger dataset and the outcome predicted by the futility analysis was largely due to patients’ greater exposure to high dose aducanumab. multiple factors contributed to the greater exposure to aducanumab in the new analysis of the larger dataset, including data on a greater number of patients, a longer average duration of exposure to high dose, the timing of protocol amendments that allowed a greater proportion of patients to receive high dose, and the timing and pre-specified criteria of the futility analysis.


biogen conference call and webcast

on october 22, 2019, at 8:00 a.m. et, biogen will host its third quarter 2019 earnings conference call, which will include a discussion of the new analysis of the larger dataset from the phase 3 studies of aducanumab. this conference call will be broadcast via the internet and will be accessible through the investors section of biogen’s website, following the live webcast, an archived version of the call will be available on the website. supplemental information in the form of a slide presentation is also accessible at the same location on the internet and will be subsequently available on the website for at least one month.


about aducanumab

aducanumab (biib037) is an investigational human monoclonal antibody studied for the treatment of early alzheimer’s disease. biogen licensed aducanumab from neurimmune under a collaborative development and license agreement. since october 2017 biogen and eisai have collaborated on the development and commercialization of aducanumab globally.

emerge and engage were phase 3 multicenter, randomized, double-blind, placebo-controlled, parallel-group studies designed to evaluate the efficacy and safety of aducanumab. the primary objective of the studies was to evaluate the efficacy of monthly doses of aducanumab as compared with placebo in reducing cognitive and functional impairment as measured by changes in the cdr-sb score. secondary objectives were to assess the effect of monthly doses of aducanumab as compared to placebo on clinical decline as measured by mmse, adas-cog 13, and adcs-adl-mci.

eisai co., ltd. (headqurters: tokyo, ceo: haruo naito, “eisai”) and meiji seika pharma co., ltd. (headqurters: tokyo, ceo: daikichiro kobayashi, “meiji”) today announced the manufacturing and marketing approval in japan for the indication of improvement of wearing-off phenomenon in patients with parkinson’s disease under treatment with a drug containing levodopa for equfina® tablets (safinamide mesilate, “safinamide”), which was developed for use in the treatment of patients with parkinson’s disease was obtained. in japan, meiji holds the manufacturing and marketing approval for safinamide, and eisai exclusively sells the safinamide.

parkinson’s disease is a neurodegenerative disease which causes motor impairment, with symptoms including tremors in the limbs, muscular rigidity and shuffling gait. it is caused by degeneration of the dopamine nervous system, which leads to a shortage of dopamine, a neurotransmitter in the brain. there are approximately 200,000 patients suffering from parkinson’s disease in japan1, and the number of patients is increasing due to the aging of the population.1, 2  drugs containing levodopa are widely used to treat parkinson’s disease by replenishing the brain’s supply of dopamine. however, as the disease progresses, levodopa’s duration of effect (“on” time) decreases, and there are cases where patients may experience wearing-off phenomena, a return of parkinson’s disease symptoms before the next dose. safinamide through its main mechanism of action as a selective monoamine oxidase b (mao-b) inhibitor, increases the density of endogenous dopamine and exogenous dopamine from levodopa-containing drugs in the brain.

this manufacturing and marketing approval is based on a double-blind, placebo-controlled phase ii/iii study (study me2125-3) to evaluate the efficacy and safety of safinamide as add-on therapy and an open label phase iii study (study me2125-4) to evaluate the safety and efficacy of long-term administration of safinamide in japanese patients with parkinson’s disease with wearing-off phenomena who are currently receiving levodopa, as well as global clinical trials.

in study me2125-3, the change in mean daily “on” time from baseline to 24 weeks of the treatment phase, which is the primary endpoint, of treatment with safinamide 50 mg and 100 mg were statistically significant compared to placebo-controlled treatment. the most common adverse drug reactions (adrs)  (incidence 3% and higher) observed with patients with safinamide 50 mg and 100 mg were dyskinesia and visual hallucination. also in study me2125-4, with regard to the change in mean daily “on” time from baseline to 52 weeks of the treatment phase, the “on” time with long-term administration of safinamide was extended, and showed the continued effectiveness. the most common adrs (incidence 3% and higher) observed with patients were dyskinesia, falls, and constipation.

by providing equifina tablets as a new option for parkinson’s disease treatment, eisai and meiji will make further contributions to address the diverse needs of, and increase the benefits provided to, parkinson’s disease patients and their families.
