Development Overview
Introduction
Aducanumab is a monoclonal antibody directed against amyloid beta developed by Neurimmune, for the treatment of Alzheimer's disease. Alzheimer's disease is caused by deposition of amyloid-β (Aβ) plaques and neurofibrillary tangles in the brain, accompanied by synaptic dysfunction and neurodegeneration. Aducanumab selectively targets soluble oligomers and insoluble fibrils embedded in the beta amyloid plaque, in the brains of patients and reduce soluble and insoluble Aβ in a dose-dependent manner. Aducanumab was discovered by Neurimmune Therapeutics using their Reverse Translational Medicine (RTM) technology platform together with a team of researchers at the University of Zurich. The technology translates antibody-encoding genetic information obtained from human white blood cells into therapeutic antibodies. A de-identified library of B cells collected from healthy elderly participants without cognitive impairment was used for the discovery of aducanumab. The drug is available in the US and United Arab Emirates and is under regulatory review in Japan, Australia, Canada, Brazil, and Switzerland for the treatment of Alzheimer's disease for intravenous formulation. Clinical development is underway in South Korea and Taiwan for intravenous formulation. Clinical development for subcutaneous formulation and intravenous formulation is underway in the US and unknown location.
In March 2015, Biogen Idec changed its name to Biogen [1] .
Company Agreements
In January 2024, Neurimmune declared the reclaiming of worldwide rights to aducanumab. In 2007, Neurimmune granted Biogen a license for aducanumab, aimed at treating and preventing Alzheimer’s disease. Now, with Biogen terminating the collaboration and license agreement, Neurimmune will retain full global rights to the program. In May 2018, Biogen and Neurimmune announced that Biogen has exercised its option to further reduce the royalty rates payable on potential future sales of aducanumab. As per the option, Neurimmune will receive $US50 million payment from Biogen in exchange for a 5% reduction in the original royalty rates on potential commercial sales of aducanumab, which follows the 15% reduction in royalty rates announced in October 2017 as a part of their amended agreement from 2017. Previously, in December 2010, Biogen Idec and Neurimmune Holding AG announced that Biogen Idec had acquired a subsidiary of Neurimmune, which includes the world-wide rights to three pre-clinical immunotherapy programs. The three programs are focused on the discovery and development of novel human antibodies that address three central nervous system targets: alpha-synuclein, tau and TDP 43. Biogen Idec will make an initial payment of $US32.5 million and up to $US395 million in contingent payments. This acquisition builds on a 2007 agreement between the two companies to explore human antibodies against beta-amyloid for the treatment and prevention of Alzheimer's disease. Biogen Idec will be responsible for the development of the pre-clinical candidates and the commercialisation of all products. Neurimmune will be responsible for additional scientific activities with respect to the lead candidates as well as the discovery of back-up candidates, utilizing its Reverse Translational Medicine™ technology platform. Neurimmune retains the right to use its platform for creating therapeutic antibody products outside the scope of its agreement with Biogen Idec. [2] [3] [4] [5] [6]
As at January 2023, Biogen announced that Eisai no longer reimburses Biogen for their share of costs associated with ADUHELM. In March 2022, Biogen Idec (now Biogen) and Eisai amended their existing collaboration agreement on aducanumab, which is commercialized in the United States as ADUHELM® (aducanumab-avwa). Effective as of January, 1, 2023, Eisai will receive a tiered royalty based on net sales of ADUHELM rather than sharing global profits and losses. The royalty rate starts at 2% and reaches 8% when annual sales exceed $US 1 billion. Effective immediately, Biogen’s existing final decision-making rights on ADUHELM have converted to sole decision making and commercialization rights worldwide. Overall, economic arrangements for both companies in 2022 are expected to remain materially unchanged with Eisai’s share of expenses capped at an agreed amount for the costs related to development, commercialization, and manufacturing of ADUHELM for the period from January 1, 2022 to December 31, 2022. Once the tiered royalty model commences on January 1, 2023, Eisai will not participate in ADUHELM’s economics beyond these royalties. Earlier in October 2017, Eisai Co Ltd and Biogen Idec expanded their agreement, with Eisai exercising its option to co-develop and co-promote Biogen’s aducanumab. Under the terms of the agreement Biogen would continue to lead the phase III development of aducanumab and will remain solely responsible for all development costs until April 2018. Eisai will then reimburse Biogen for 15% of expenses from April 2018 through December 2018, and 45% from January 2019 onwards. Neither company is making any upfront payments associated with the exercise of the aducanumab option. Furthermore, Eisai’s and Biogen’s respective milestone payments under the original agreement for aducanumab and BAN 2401 were eliminated. The companies will continue to jointly develop elenbecestat and BAN 2401. Previously in March 2014, Eisai and Biogen entered into a collaboration to develop and commercialise Eisai's drug candidates for the treatment of Alzheimer's disease, BAN 2401 and E 2609 (elenbecestat) [see ADIS Insight drug profile800034837]. Both companies will co-develop and co-market the products in major markets, including Japan, the US and the EU. Eisai and Biogen will share research and development costs with Eisai booking all sales and with profits to be split between the companies.

Key Development Milestones
As of December 2021, aducanumab (ADUHELM) 100 mg/mL injection for intravenous use has been approved in the United Arab Emirates (UAE) for the treatment of Alzheimer’s disease [15]
As of August 2021, aducanumab (ADUHELM™) has been launched in the US for the treatment of Alzheimer’s disease [16] . In June 2021, the US FDA granted accelerated approval for aducanumab (ADUHELM™), for the treatment of Alzheimer’s disease. The approval was based on data from the phase III EMERGE, ENGAGE and PRIME clinical trials [see trials below], demonstrating the effect of the drug on reducing amyloid beta plaques. Under the accelerated approval provisions, Biogen needs to conduct a new randomised, controlled clinical trial to verify the drug’s clinical benefit. If the trial fails to verify clinical benefit, the FDA may initiate proceedings to withdraw approval of the drug. Earlier, in January 2021, the US FDA extended the review period by three months for the Biologics License Application (BLA) for aducanumab and granted new Prescription Drug User Fee Act (PDUFA) action date of June 7, 2021. The US FDA, in August 2020, accepted for priority review, and granted a Prescription Drug User Fee Act (PDUFA) action date of March 7, 2021, for. The FDA also stated that there may be a possibility of early action on the application, under an expedited review. In November 2020, data were presented and opinions were expressed for the review process at the FDA Advisory Committee meeting. Earlier, in July 2020, following a pre-BLA meeting, Biogen completed the rolling BLA submission, which was initiated in April 2020. The submission package included data from the phase III EMERGE and ENGAGE studies, and the phase Ib PRIME study [17] [18] [19] [20] [21] [22] [23] [24] [25] .
In the first quarter of 2021 Biogen submitted a marketing authorisation application (MAA) to Agência Nacional de Vigilância Sanitária (ANVISA), Brazil for aducanumab for Alzheimer’s disease treatment. The application is in queue for review [26] [27] .
In the first quarter of 2021, Biogen submitted marketing authorisation applications for aducanumab to Health Canada, the Therapeutic Goods Agency in Australia, and Swissmedic in Switzerland, all of which are subject to agency validation of whether the applications are accepted [26] [27] .
In December 2021, Biogen announced that the First Committee on New Drugs (NDC) of the Pharmaceutical Affairs and Food Sanitation Council that advices the Ministry of Health, Labour and Welfare (MHLW) in Japan decided to continue deliberations on the application for the manufacturing and marketing approval of aducanumab for the treatment of Alzheimer’s disease. The NDC is seeking additional data to be submitted as part of this process. The companies intends to continue to actively engage with the Pharmaceuticals and Medical Devices Agency (PMDA) in Japan to agree on additional data requirements [28] . Earlier, in December 2020, Biogen has submitted Japanese New Drug Application (J-NDA) to the Ministry of Health, Labor and Welfare (MHLW) for aducanumab in the treatment of Alzheimer’s disease [29] .
In April 2022, Biogen withdrew its application for a marketing authorisation of aducanumab (Aduhelm) 100 mg/mL concentrate for solution for infusion, which was intended to be used as a disease modifying treatment in adult patients with Alzheimer’s disease at the mild cognitive impairment (MCI) or mild dementia stage. This withdrawal was based on interactions with the Committee for Medicinal Products for Human Use (CHMP) indicating that the data provided thus far would not be sufficient to support a positive opinion on the marketing authorization of aducanumab. Biogen confirms there are no consequences of the withdrawal on ongoing clinical trials with aducanumab [30] [31] . In December 2021, Biogen announced that, the CHMP of the European Medicines Agency (EMA) has adopted a negative opinion on the Marketing Authorization Application (MAA) for aducanumab for the treatment of the early stages of Alzheimer’s disease known as MCI due to Alzheimer’s disease and mild Alzheimer’s disease dementia. This decision is aligned to the negative trend vote of the committee in November 2021. Biogen will seek a re-examination of the opinion by the CHMP. The European Commission’s regulations allow an applicant to request a re-examination of a CHMP opinion, followed by submission of documentation with detailed grounds for the request. In November 2021, Biogen and Eisai announced that following an oral explanation held at the November meeting of the CHMP of the European Medicines Agency (EMA), Biogen received a negative trend vote on the aducanumab Marketing Authorization Application for aducanumab 100 mg/mL concentrate solution for infusion for the treatment of Alzheimer’s disease. The CHMP may adopt a formal opinion on the Marketing Authorization Application at its December meeting (December 13-16, 2021). Biogen intends to continue to engage with the EMA and CHMP as it considers next steps towards the goal of providing access to aducanumab to patients in Europe [32] . Earlier, in November 2021, Biogen and Eisai announced that following an oral explanation held at the November meeting of the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA), Biogen received a negative trend vote on the aducanumab Marketing Authorization Application for aducanumab 100 mg/mL concentrate solution for infusion for the treatment of Alzheimer’s disease. The CHMP may adopt a formal opinion on the Marketing Authorization Application at its December meeting (December 13-16, 2021). Biogen intends to continue to engage with the EMA and CHMP as it considers next steps towards the goal of providing access to aducanumab to patients in Europe [32] . In October 2020, Biogen announced that European Medicines Agency (EMA) accepted Marketing Authorization Application (MAA) of Aducanumab for the treatment of Alzheimer's Disease for review, following a standard timetable. The MAA was submitted in the same month. The MAA included efficacy, safety and biomarker data from a global, multi-study clinical development program which included approximately 3,600 patients in more than 20 countries [15] [33] [34] .
In April 2017, the Japanese MHLW granted SAKIGAKE designation system to aducanumab for the treatment of Alzheimer’s disease in Japan [35] .
In August 2016, Biogen reported that aducanumab was granted fast track designation by the US FDA, for treatment of early Alzheimer's disease [36] .
In June 2016, the EMA granted the PRIME (priority medicines) designation to aducanumab for the treatment of Alzheimer’s disease. The PRIME status was granted based on the results of the phase Ib PRIME trial [see below] [37] .
In October 2019, Biogen reported that after consulting with the US FDA, the company intends to pursue regulatory approval for aducanumab, based on a new analysis conducted by Biogen, of a larger dataset from the phase III clinical studies that were discontinued in March 2019 following a futility analysis. Significant benefits on measures of cognition and function such as memory, orientation, and language were reported in patients who received aducanumab. The analysis includes additional data available after the pre-specified futility analysis demonstrating that aducanumab is pharmacologically and clinically active. The BLA submission will also include data from the phase I/Ib [see below] and phase III [see below] studies. Biogen also intends to offer access to aducanumab to eligible patients previously enrolled in the phase III studies, the long-term extension study for the phase Ib PRIME [see below] study, and the EVOLVE [see below] safety study [38] .
In October 2019, the Alzheimer's Association reported that Biogen will pursue regulatory approval from the US FDA for aducanumab based on phase III trial results from the EMERGE and ENGAGE studies. The company plans to offer access to aducanumab to eligible patients previously enrolled in the phase III studies, the long-term extension of the phase Ib study, and a safety study [39] .
As of April 2019, aducanumab was no longer reflecting on Biogen's pipeline and Neurimmune Therapeutics' pipeline, and based on the results of phase III ENGAGE and EMERGE trials, it seemed that the drug development was discontinued (Neurimmune Therapeutics pipeline and Biogen pipeline, April 2019).
In July 2021, Biogen and Eisai released pooled results of the PRIME, EMERGE and ENGAGE trials [40] . In June 2021, pooled efficacy data for aducanumab in Alzheimer's disease from three clinical trials was released by Biogen [18] . In the same month, pooled safety and pharmacodynamics results from the phase III EMERGE and ENGAGE trials were presented at the Alzheimer's Association International Conference 2021 (AAIC-2021) [41] [42] . Later, in November 2021, updated pre-specified pooled analysis from the two pivotal phase III trials namely; EMERGE and ENGAGE trials [see below] were released by Biogen [43] . In March 2022, Biogen released pooled analysis from the two pivotal phase III trials [44] . In April 2022, pooled efficacy data from the phase III PRIME, EMERGE and ENGAGE trials were presented at the 74th Annual Meeting of the American Academy of Neurology (AAN-2022) [45] [46] . In July 2022, the company presented pooled efficacy data from two phase III trials EMERGE and ENGAGE (See Below) at the Alzheimer's Association International Conference (AAIC-2022) [47] .
In February 2024, Aducanumab was in phase III development for the treatment of Alzheimer's disease for subcutaneous administration in unknown location (Neurimmune pipeline, February 2024).
In January 2024, Neurimmune terminated the phase IIIb/IV ENVISION trial due to sponsor's decision which was not related to safety. The trial was designed to verify the clinical benefit of monthly doses of aducanumab in slowing cognitive and functional impairment as measured by changes in the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) score as compared with placebo in participants with early Alzheimer's disease (NCT05310071). A multicenter, randomized, double-Blind, placebo-controlled study was initiated in June 2022 and enrolled 1512 participants in Australia, Belgium, Brazil, Canada, Finland, France, Germany, Italy, Japan, South Korea, Mexico, Poland, Portugal, Spain, Sweden, United Kingdom, United States [48] [49] .
In September 2023, Biogen terminated a phase IIIb EMBARK trial, which resulted in termination costs of approximately $US 43.0 million. The trial was designed to evaluate the long-term safety and tolerability of aducanumab after a wash-out period imposed by discontinuation of feeder studies in participants who had previously received aducanumab (previously treated patients) or who had previously received placebo (treatment-naïve patients) (participated in the aducanumab studies PRIME, EVOLVE, EMERGE and ENGAGE; or 221AD103, 221AD301, 221AD302 and 221AD205) (221AD304; EudraCT2019-004368-22; NCT04241068). The open-label, single group assignment trial was initiated in March 2020 and enrolled 1695 patients in the US, Australia, Austria, Belgium, Denmark, Canada, Finland, France, Germany, Italy, Japan, South Korea, Netherlands, Poland, Portugal, Spain, Sweden, Switzerland, Taiwan, United Kingdom [50] . In November 2020, study design of the ongoing trial was presented at the 2020 Clinical Trials on Alzheimer's Disease digital conference [51] [52] . In April 2022, the company presented data at the 74th Annual Meeting of the American Academy of Neurology 2022 (AAN - 2022) and demonstrated that Aβ plaque reduction achieved with aducanumab treatment persisted during the treatment gap [53] .
In October 2019, Biogen reported that the phase III EMERGE trial that assessed the efficacy and safety of two dosages of aducanumab in patients with early Alzheimer's disease met its primary endpoint showing a significant reduction in clinical decline in Clinical Dementia Rating-Sum of Boxes (CDR-SB) scores (221AD302; NCT02484547; EudraCT2015-000967-15) [38] . The double-blind, randomized trial was initiated in July 2015 and completed enrolment of 1 683 patients in the second quarter of 2018, in the US, Belgium, Canada, Finland, France, Germany, Italy, Japan, Netherlands, Poland, Spain, Sweden, Switzerland [54] . Earlier, in March 2019, Biogen and Eisai terminated the trial based on analysis by an independent data monitoring committee which indicated that the trial was unlikely to meet the primary endpoint upon completion. There were no safety concerns regarding the study drug. In March 2021, efficacy data from the trial was Biogen [55] [56] [57] [58] [59] . In July 2021, Biogen and Eisai released updated results of the trial. The results were presented at the Alzheimer's Association International Conference (AAIC-2021) [60] [40] .
In October 2019, Biogen reported that the phase III ENGAGE trial that assessed the efficacy and safety of two dosages of aducanumab in patients with early Alzheimer's disease did not meet the primary endpoint (221AD301; NCT02477800; EudraCT2015-000966-72). The trial was discontinued in March 2019, based on analysis by an independent data monitoring committee which indicated that the trial was unlikely to meet the primary endpoint upon completion. There were no safety concerns regarding the study drug. The double-blind, randomised trial was initiated in June 2015 and completed enrolment of 1 605 patients in the second quarter of 2018, in the US, Australia, Austria, Canada, Denmark, France, Germany, Italy, Japan, Portugal, South Korea, Spain, Taiwan, and the United Kingdom [61] . The first patient was enrolled in September 2015, thereby triggering a $US60 million milestone payment to Neurimmune [38] [56] [57] [62] [63] [58] .
In March 2019, Biogen and Eisai initiated phase III secondary prevention trial for aducanumab in Alzheimer disease [56] [64] .
In March 2019, Biogen and Eisai terminated the phase II EVOLVE trial intended to evaluate the safety of aducanumab dosing in asymptomatic amyloid-related imaging abnormalities (ARIA) in patients with mild cognitive impairment due to Alzheimer's disease or with mild AD dementia, based on futility analysis and not based on safety concerns (EudraCT2018-002102-31; 221AD205; NCT03639987). The decision was taken following discontinuation of phase III trials EMERGE and ENGAGE [see above]. The randomised, double-blind, placebo-controlled trial was initiated in December 2018 and intended to enrol approximately 500 patients in the US, the UK, France, Italy and Spain [56] [65] .
In July 2022, Biogen completed a phase I trial that was designed to assess the pharmacokinetic comparability of 2 fixed subcutaneous doses of aducanumab (BIIB 037) with a single, weight-based intravenous dose in healthy volunteers (221HV104; NCT05216887). The randomized, open-label trial initiated in February 2022, enroled 123 volunteers in the US [66] .
In October 2021, Biogen in collaboration with Eisai Co Ltd, completed a phase I trial of aducanumab (NCT04924140; 221HV103). The primary objective of the study is to evaluate the absolute bioavailability of a single, fixed subcutaneous (SC) dose of aducanumab, compared with a single weight-based intravenous (IV) dose of aducanumab, in healthy volunteers. The secondary objectives of the study are to assess the safety and tolerability of aducanumab, administered SC in healthy volunteers, and to characterise additional pharmacokinetic (PK) parameters of a single, fixed SC dose of aducanumab and a weight-based IV dose of aducanumab in healthy volunteers. The randomised, open-label, parallel-arm study was initiated in June 2021 and enrolled 30 volunteers, aged 40 to 70 years, in the US [67] .
In December 2016, Biogen completed a randomised, double-blind, placebo-controlled phase I trial that assessed the safety, tolerability, pharmacokinetics and immunogenicity of single and multiple ascending doses of aducanumab in patients with mild to moderate Alzheimer's disease (NCT02434718; 221AD104). The trial was initiated in May 2015 and enrolled 21 patients aged 55 to 85 years, in Japan [68] .
In November 2016, Biogen completed a phase I trial which evaluated the absolute bioavailability, safety and tolerability of a single, fixed subcutaneous (SC) dose of aducanumab compared with a single, weight-based intravenous (IV) dose in healthy volunteers and to characterise the pharmacokinetics of aducanumab (221HV102; NCT02782975). The randomised, open-label trial initiated in May 2016, enrolled 28 volunteers in the US [69] .
In August 2013, Biogen Idec completed a phase I trial, which investigated the safety, tolerability and pharmacokinetics of single ascending doses of aducanumab in patients with mild to moderate Alzheimer's disease (NCT01397539). The randomised, double-blind trial was initiated in June 2011 and enrolled 53 patients in the US [70] . Interim results were presented at the 2013 Alzheimer's Association International Conference in July 2013 [71] [72] . Biogen Idec submitted the IND for the trial in April 2011 [73] .
In In March 2019, the long-term extension phase of the randomised, double-blind, placebo-controlled phase Ib PRIME trial was discontinued which was planned to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of multiple doses of aducanumab in patients with Alzheimer's disease, based on futility analysis and not safety concerns (NCT01677572; EudraCT2012-000349-10). The trial was initiated in October 2012. The primary endpoint is tolerability, assessed from baseline to 30 weeks. Enrolment of 197 patients aged 50 to 90 years was completed in the US in August 2015 [74] . Patients completing the one-year placebo-controlled portion of the study had a long-term extension further. Positive interim results were reported in December 2014 and March 2015. Updated results from the trial were reported in March 2018 [75] [76] [59] . Positive results from a phase Ib study of aducanumab (BIIB037) analysis were presented at the Alzheimer’s Association International Conference in July 2015 (AAIC-2015) [77] . In December 2016, interim results from the titration cohort as well as data from the first year of the long-term extension (LTE) study were released by the company [78] . Updated results from the LTE study for patients treated with aducanumab up to 24 months in the titration cohort and up to 36 months in the fixed-dose cohorts were reported in August 2017 [35] . In November 2017, Biogen released new efficacy data from the phase Ib long-term extension trial. Safety data from the LTE was reported in March 2018. Additional safety data was released in August 2018 [79] [75] [80] . The decision was taken following discontinuation of phase III trials EMERGE and ENGAGE [see above] [56] . In May 2019, data from the long term extension trial were released at the American Academy of Neurology (AAN- 2019) [81] . In March 2022, data from the long term extension trial were released by the company [44] .
In August 2016, Biogen released results from structural analysis designed to understand the epitope targeted by aducanumab and its binding profile relative to other therapies that showed less efficacy. The study demonstrated that aducanumab was highly selective for aggregated forms of beta-amyloid, including soluble oligomer and insoluble fibril and that non-binding to monomer was critical [82] .

Aducanumab indicated pharmacokinetic activity and exposure linear with dosage, during the phase I PRIME study in patients with Alzheimer's disease. The pharmacokinetics of aducanumab was not affected by transient treatment-related immunogenicity, which was seen in 3% of patients. The interim results were reported from the randomised, double-blind trial that enrolled 165 patients in the placebo, 1 mg/kg, 3 mg/kg and 10 mg/kg and 6 mg/kg cohorts [59] .
Ascending doses of aducanumab demonstrated a predictable pharmacokinetic profile in patients with mild-to-moderate Alzheimer's disease in a phase I trial in 56 patients with Alzheimer's disease. The aducanumab exposures (AUC∞) were linear throughout the dosage range of 0.3-30 mg/kg. The mean serum t1/2 was approximately 18 days, and was consistent between 1 and 30 mg/kg doses. The coefficient of variance for both AUC∞ and t1/2 was generally less than 30% [72] .
Adverse Events
Phase III:
The results form the phase III EMERGE and ENGAGE trials showed that amyloid-related imaging abnormalities-edema (ARIA-E) and headache were the most commonly reported adverse events. 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 sequel. In the 10-mg/kg group (n=1029 with 1 postbaseline MRI), ARIA-E was the most common adverse event (35.2%), with a higher incidence in apolipoprotein e4 carriers compared with noncarriers (43.0% versus 20.3%, respectively). ARIA-E typically occurred within the first 32 weeks of treatment with aducanumab and were mostly asymptomatic (74.0%). Most events (98.2%) of ARIA-E resolved on study, with the majority resolving within 12-16 weeks. The majority of symptoms during ARIA were characterized as mild (67.7%) or moderate (28.3), the most common symptoms were headache (46.6%), confusion (14.6%), dizziness (10.7%) and nausea (7.8%). ARIA-E were transient but recurred in 10.6% of participants in the 10-mg/kg group. ARIA-H microhemorrhage and superficial siderosis were typically asymptomatic and more common in participants who had ARIA-E (40.3% and 38.7%, respectively), compared with participants without ARIA-E (7.6% and 1.6%, respectively) [41] [38] [44] .
Phase I:
Aducanumab indicated an acceptable safety and tolerability profile during the phase I PRIME study in patients with Alzheimer's disease. The most commonly reported adverse events were amyloid-related imaging abnormalities (ARIA). The incidence of ARIA edema was observed early in the course of treatment and was asymptomatic or with mild, transient symptoms and led to dose-reduction. ApoE4 carriers indicated 5% incidence of ARIA oedema in the 1 mg/kg and 3 mg/kg groups, 43% in the 6 mg/kg group and 55% in the 10 mg/kg group, of which 5%, 10% and 35% patients discontinued treatment in the 1 mg/kg, 6 mg/kg an 10 mg/kg cohorts. In the titration arm the incidence of ARIA-E in ApoE4 carriers was 35%. ApoE4 non-carriers indicated ARIA oedema incidence of 0%, 9%, 11% and 17% in the 1 mg/kg, 3 mg/kg, 6 mg/kg and 10 mg/kg groups, respectively, of which 11% and 8% patients discontinued treatment in the 6 mg/kg and 10 mg/kg cohorts. Headache was seen in 22% patients receiving aducanumab, relative to 5% patients receiving placebo. Three deaths were reported in the study, two in the placebo group and one in the aducanumab 10 mg/kg group, none of which were related to the study. Other observed adverse and serious adverse events were consistent with those seen in the study population. The interim results were reported from the randomised, double-blind trial that enrolled 165 patients in the placebo, 1 mg/kg, 3 mg/kg and 10 mg/kg and 6 mg/kg cohorts. In the phase Ib LTE, the most commonly reported adverse events were headache, fall and amyloid-related imaging abnormalities (ARIA). Of the 185 patients dosed with aducanumab in the study, 46 patients experienced ARIA-E (oedema) and 61% were asymptomatic. Eight patients experienced more than one episode of ARIA-E. No new cases of ARIA-E were found in patients initially randomised to aducanumab 3, 6 or 10 mg/kg who were treated up to 24 months. The incidence of ARIA events in patients switching from placebo to aducanumab was consistent with the incidence reported in placebo-controlled portion of phase Ib [81] [35] [78] [76] [59] [74] .
Aducanumab (at dosages of 0.3-30 mg/kg) was generally well tolerated in a phase I trial in 56 patients with mild-to-moderate Alzheimer's disease. To date, 21 patients reported 43 treatment-emergent adverse events. All the events reported were either mild or moderate in intensity, with 15 (all mild) considered possibly related to aducanumab. The most common events reported were headache (15%), diarrhoea (8%), and dizziness (8%). The incidence and severity of the adverse events were not related with the dosage. No cases of amyloid-related imaging abnormalities (ARIA) were reported [71] .
In the long-term extension of phase Ib study, the most commonly reported adverse events were headache, fall, and amyloid-related imaging abnormalities (ARIA). Of the 185 patients dosed with aducanumab, 46 patients experienced ARIA-E (oedema). There were no new cases of ARIA-E in patients who continued on the same dose of aducanumab. Eight patients experienced more than one ARIA events, mild in nature, in the early course of treatment, which got resolved or stabilised within 4-12 weeks. Most common AEs were headache, fall and ARIA. The trial enrolled patients with prodromal or mild Alzheimer's disease [79] [75] [74] .
Pharmacodynamics
Summary
Phase III:
Pooled results form the phase III EMERGE and ENGAGE trials demonstrated that the amyloid positron emission tomography (PET) composite standard uptake value ratio (SUVR) subgroup analysis revealed a consistent dose- and time-dependent Aß reduction advantage of high-dose and low-dose aducanumab over placebo in each of the prespecified 13 subgroups. Also, these results were consistent with the overall results of the amyloid PET biomarker substudies in which the aducanumab treatment was associated with robust dose-dependent reduction in brain Aß levels. The results were obtained from participants that were randomised (1:1:1) to receive high-dose aducanumab, low-dose aducanumab, or placebo, via intravenous injection, every 4 weeks, for 18 months and the longitudinal amyloid PET imaging using 18F-florbetapir was performed in a subset of patients (n=488 in EMERGE; n=585 in ENGAGE) at screening, Week 26 and Week 78 [42] [54] [61] .
Pooled analysis
Pooled group-level analysis of three trials (phase Ib PRIME trial, phase III EMERGE and ENGAGE trials), in patients with Alzheimer's disease demonstrated a positive association between aducanumab treatment effect on brain amyloid beta (Aß) plaques and clinical measures across dose groups and studies, with the exception of the high-dose group from ENGAGE trial. In second set of analyses of EMERGE and PRIME trials, a greater reduction in brain Aß plaque levels was associated with less decline across clinical endpoints in each study. In EMERGE trials, greater reduction in brain Aß plaque levels was also associated with greater reduction in cerebrospinal fluid (CSF) markers of tau and neurodegeneration as well as less decline on clinical endpoints. Several of these relationships were not apparent in ENGAGE, in which a clinical treatment effect of aducanumab was not observed. The third analysis showed that a smaller magnitude of clinical decline was observed in patients in PRIME, EMERGE and ENGAGE trials, whose brain Aß plaque levels were lowered to a threshold considered to be amyloid negative relative to patients who did not reach this threshold. These results were consistent with the hypothesised mechanism of action of aducanumab and supported relationship between aducanumab-induced changes in biomarkers of Alzheimer's disease pathophysiology and slowing of clinical decline [40] [74] [61] [54] .
Treatment with aducanumab indicated a dose- and time-dependent reduction of amyloid plaque over 54 weeks of treatment, during the phase I PRIME trial. At 54 weeks, patients receiving aducanumab (10 mg/kg) experienced a 69% reduction from baseline in amyloid plaque as observed on the Centiloid Conversion scale (p<0.001 versus placebo). There was no change from baseline in the placebo arm [75] . Aducanumab treatment reduced amyloid plaque by - 0.087 (p < 0.01) in the 3 mg/kg cohort, by - 0.143 (p < 0.001) in the 6 mg/kg cohort and by - 0.205 (p < 0.001) in the 10 mg/kg cohort, compared with placebo, at 26 weeks. At week 54, the reduction of amyloid plaque in the 3 mg/kg cohort was - 0.139 (p < 0.001) and in the 10 mg/kg cohort was - 0.266 (p < 0.001). The reduction of amyloid plaque in the 1 mg/kg arm was - 0.056 at week 54 and - 0.030 at week 26, which were not significant. The composite standardized uptake value ratio for the placebo treatment arm was unchanged at 26 and 54 weeks. The interim results were reported from the randomised, double-blind trial that enrolled 165 patients in the placebo, 1 mg/kg, 3 mg/kg and 10 mg/kg and 6 mg/kg cohorts [59] [74] .
Therapeutic Trials
Phase III:
Updated results of the double-blind, randomised, phase III EMERGE trial in patients with early Alzheimer's disease, demonstrated reduced clinical decline with high-dose aducanumab treatment, evidenced by a statistically significant treatment effect on pre-specified primary and secondary clinical efficacy endpoints, when compared with placebo. Treatment effects were observed across all six domains (three cognitive and three functional) measured by Clinical Dementia Rating-Sum of Boxes (CDR-SB), the primary endpoint of the trial. Aducanumab treatment effects were observed across ADAS-Cog13 items sensitive to cognitive change in early symptomatic Alzheimer’s disease and across a broad range of items measuring ability to conduct activities of daily living, as measured by ADCS-ADL-MCI, the secondary endpoint of the trial. Aducanumab treatment was also associated with a reduction in the behavioral and psychiatric symptoms of Alzheimer’s disease, as measured by the Neuropsychiatric Inventory-10 (NPI-10), the tertiary efficacy endpoint of the trial [40] . Interim results from this trial, patients on placebo showed from baseline to week 50 a mean decline in cognition of approximately -2.2 points on MMSE, an 8.3% decline, and from baseline to week 78 approximately -3.3 points on MMSE, a 12.5% decline, respectively. Mean baseline MMSE score was 26.4 [55] . The results from the phase III EMERGE trial showed that the patients treated with high dose aducanumab exhibited significant reduction of clinical decline from baseline in Clinical Dementia Rating-Sum of Boxes (CDR-SB) scores at 78 weeks (22% versus placebo, P = 0.01). The patients also demonstarted a consistent reduction of clinical decline as measured by the pre-specified secondary endpoints like the Mini-Mental State Examination (MMSE; 18% versus placebo, P = 0.05), 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), thus, indicating significant slowing of decline on measures of cognition and function, as well as activities of daily living. The amyloid plaque burden was reduced with low and high dose aducanumab compared to placebo at 26 and 78 weeks (P < 0.001), as depicted by imaging of amyloid plaque deposition [24] [38] [54] .
Phase I:
New data from the long-term extension of phase Ib study, at 24, 36 and 48 months demonstrated a continued decrease of amyloid plaque in a dose and time dependent manner in the fixed-dose cohorts in patients with Alzheimer's disease. ADUHELM significantly reduced amyloid beta plaque levels out to week 132. The data also indicated that ADUHELM continued to decrease plasma p-tau181 levels at 128 weeks. Patients with more effective amyloid beta clearance (SUVR lower than 1.1 by 78 weeks) also had greater decreases in p-tau181 at week 128 [44] .The average decline on the Clinical Dementia Rating sum of boxes (CDR-SB) at 24 weeks was 2.32, 2.98 and 1.69 points in the 3 mg/kg, 6 mg/kg and 10 mg/kg groups, respectively, versus 2.65 in the placebo group. A 3.25 points average decline was reported in patients who switched from placebo to aducanumab and a 3.52 points in those who switched from 1 to 3 mg/kg at 12 months. The average decline on the MMSE at 24 weeks was 2.81, 5.20 and 1.97 points in the 3 mg/kg, 6 mg/kg and 10 mg/kg groups, respectively versus 1.95 in the placebo group. A 4.28 points average decline was reported in those who switched from placebo to aducanumab and 3.65 points in those who switched from 1 to 3 mg/kg at 12 months. The average decline on the Clinical Dementia Rating sum of boxes (CDR-SB) at 36 weeks, was 3.86, 4.49 and 2.84 points in the 3 mg/kg, 6 mg/kg and 10 mg/kg groups, respectively. A 5.28 points average decline was reported in patients who switched from placebo to 3 mg/kg or 3-6 mg/kg and a 6.11 points in those who switched from 1 to 3 mg/kg at 12 months. The average decline on the MMSE at 36 weeks was 4.83, 8.97 and 4.10 points in the 3 mg/kg, 6 mg/kg and 10 mg/kg, respectively. A 7.98 points average decline was reported in those who switched from placebo to 3 mg/kg or 3-6 mg/kg and 6.35 points in those who switched from 1 to 3 mg/kg at 12 months. At 48 months, the average decline on the CDR-SB was 5.57, 7.75 and 3.87 in the 3 mg/kg, 6 mg/kg and 10 mg/kg groups, respectively [85] [80] . Earlier results included that, aducanumab demonstrated statistically significant reduction in beta amyloid in the brain and dose-dependent slowing of clinical decline in patients with Alzheimer's disease, in the phase I PRIME study. A statistically significant reduction of amyloid plaque was observed in patients treated with 1mg/kg [-0.050 (p < 0.05)], 3mg/kg [-0.130 (p < 0.001)], 6mg/kg [-0.206 (p < 0.001)] and 10mg/kg [-0.263 (p < 0.001)] of the drug and in the titration arm [-0.171 (p < 0.001)]. Alzheimer's disease related impairment measured using MMSE, indicated worsening of 2.21 points in the 1 mg/kg arm, 0.75 points in the 3 mg/kg arm, 1.99 points in 6 mg/kg arm and 0.55 points in the 10 mg/kg arm, compared with 2.45 points in the placebo group, at one year. The 3 mg/kg and 10 mg/kg doses indicated a statistically significant slowing of cognitive decline on the MMSE (p < 0.05), relative to placebo. The Clinical Dementia Rating sum of boxes (CDR-SB) showed a worsening of 1.69, 1.33, 1.09 and 0.63 in the 1 mg/kg, 3 mg/kg, 6 mg/kg and 10 mg/kg groups, respectively, versus 1.89 in the placebo group, at 54 weeks. Statistical significance was observed in the 10 mg/kg group (p < 0.05). The interim results were from 165 patients who were randomised to placebo, 1 mg/kg, 3 mg/kg and 10 mg/kg and 6 mg/kg cohorts of aducanuab. Analyses of exploratory clinical endpoints, CDR-SB and the MMSE, were consistent with the results from the fixed-dose cohorts and suggested a continued benefit on the rate of clinical decline. At 36 months, the results suggested a continued benefit on the rate of clinical decline during the third year of treatment [35] [78] [77] [76] [59] [74] .
Pooled analysis
Pooled results from the EMERGE and ENGAGE studies showed that tau, ptau181 and Abeta42 demonstrated overall percent agreement (OPA) of 69%, 83%, and 89%, respectively, and CSF biomarker ratios demonstrated increased diagnostic accuracy (OPA≥95% for all ratios assessed). The Elecsys® Gen2 cutoff had high sensitivity (93%), specificity (82%), and OPA (92%) [47] . Updated pooled results from EMERGE and ENGAGE study showed a consistent dose- and time-dependent advantage of high- and low-dose aducanumab over placebo in the prespecified subgroups measured by positron emission tomography (PET) composite standard uptake value ratio (SUVR) [45] . Updated pooled analysis from two phase III EMERGE and EMERGE trials demonstrated that treatment with aducanumab significantly lowered plasma p-tau181 in a dose- and time-dependent manner vs. placebo. The change in plasma p-tau181 was significantly correlated with change in amyloid beta plaque and reduced cognitive and functional decline on all primary and secondary outcome measures. . The effect was greater with higher doses and longer duration of treatment. Greater reduction in plasma p-tau181 also had a statistically significant correlation with less decline in cognition and function in aducanumab treated patients. Furthermore, the analysis also demonstrated a statistically significant correlation between change in plasma p-tau181 and lowering of amyloid beta plaque, showing the effect of aducanumab on the two core pathological features of Alzheimer’s disease. In the EMERGE high-dose group, p-tau decreased 13% from baseline (p<0.001), while placebo rose 8%; in the ENGAGE high-dose group, p-tau decreased 16% from baseline (p<0.001), while placebo rose 9%. Greater reduction in plasma p-tau181 was correlated with less clinical decline in all four clinical outcome measures in both the trials. Correlation values across the endpoints for EMERGE and ENGAGE were Clinical Dementia Rating Sum of Boxes Score (CDR-SB) R = 0.11 (p = 0.0166) and R = 0.14 (p = 0.0005); Mini-Mental State Examination (MMSE) R = -0.21 (p < 0.0001) and R = -0.15 (p = 0.0002); Alzheimer’s Disease Assessment Scale–Cognitive Subscale (ADAS-Cog 13) R = 0.17 (p = 0.0001) and R = 0.15 (p = 0.0002); and Alzheimer’s Disease Cooperative Study/Activities of Daily Living scale adapted for MCI (ADCS-ADL-MCI) R = -0.12 (p = 0.0086) and R = -0.14 (p = 0.0010). Changes in plasma p-tau181 was also significantly correlated with change in amyloid beta positron emission tomography (PET) standardized uptake value ratio (SUVR): EMERGE R = 0.38, p < 0.0001; ENGAGE R = 0.42, p < 0.0001 [43] [52] [54] . Earlier results showed that patients receiving the treatment had significant dose-and time-dependent reduction of amyloid beta plaque, while patients in the control arm of the studies had no reduction of amyloid beta plaque [18] . Data from both phase III studies exhibited that clinical decline was reduced in participants who had plasma p-tau181 reduction at 78 weeks. Data indicated that patients with a reduction in plasma p-tau181, an exploratory endpoint, had less clinical progression across all four clinical endpoints (CDR-SB, MMSE, ADAS-Cog13, and ADCS-ADL-MCI) measuring cognition and function in both phase III trials at week 78 [44] .
Pooled results from PRIME, ENGAGE and ACHIEVE trials showed that the correlation analyses between biomarkers and clinical measures indicated aducanumab-induced reduction in biomarkers of AD disease pathophysiology and was associated with slowed clinical decline. EMERGE suggested that aducanumab-induced reductions in AD biomarker levels are associated with slowing cognitive decline. Analyses from PRIME were supportive of these findings. In ENGAGE, correlations were less apparent. However, group-level analyses based on data from PRIME, EMERGE, and ENGAGE demonstrated a correlation between aducanumab treatment effect on amyloid pathology and clinical measures [46] [74] [61] [54] .
