STOCKHOLM, Sept. 28, 2022 /PRNewswire/ — BioArctic AB’s (publ) (Nasdaq Stockholm: BIOA B) associate Eisai as we speak introduced optimistic topline outcomes for the big international Phase 3 confirmatory Clarity AD study in 1,795 topics. The study met the primary endpoint (CDR-SB1: Clinical Dementia Rating-Sum of Boxes) displaying a extremely statistically important discount of scientific decline. All key secondary endpoints have been additionally met demonstrating extremely statistically important outcomes. Clarity AD is a scientific trial of lecanemab (improvement code: BAN2401), an investigational anti-amyloid beta (Aβ) protofibril antibody for the remedy of gentle cognitive impairment (MCI) on account of Alzheimer’s disease (AD) and gentle AD (collectively generally known as early AD), with confirmed presence of amyloid pathology in the mind. The relative danger in Clarity AD of the principle aspect impact related with anti-amyloid therapies, ARIA, was inside expectations. Eisai will talk about this information with regulatory authorities in the U.S., Japan and Europe with the purpose to file for conventional approval in the US and for advertising and marketing authorization functions in Japan and Europe by the tip of the primary quarter of 2023. Additionally, Eisai will current the Clarity AD study outcomes on November 29, 2022, on the Clinical Trials on Alzheimer’s Disease convention (CTAD) and publish the findings in a peer-reviewed medical journal.
Lecanemab remedy met the primary endpoint and diminished scientific decline on the worldwide cognitive and practical scale, Clinical Dementia Rating-Sum of Boxes (CDR-SB) in contrast with placebo at 18 months by 27%, which represents a remedy distinction in the rating change of -0.45 (p=0.00005) in the evaluation of Intent-to-treat (ITT) inhabitants. Starting as early as six months, throughout all time factors, the remedy confirmed extremely statistically important modifications in CDR-SB from baseline in comparison with placebo (all p-values have been lower than 0.01). All key secondary endpoints have been additionally met with extremely statistically important outcomes in contrast with placebo (p<0.01). Key secondary endpoints have been the change from baseline at 18 months in contrast with placebo of remedy in amyloid ranges in the mind measured by amyloid positron emission tomography (PET), the AD Assessment Scale-cognitive subscale14 (ADAS-cog 14), AD Composite Score (ADCOMS) and the AD Cooperative Study-Activities of Daily Living Scale for Mild Cognitive Impairment (ADCS MCI-ADL).
The incidence of amyloid-related imaging abnormalities-edema/effusion (ARIA-E), an antagonistic occasion related with anti-amyloid antibodies, was 12.5% in the lecanemab group and 1.7% in the placebo group. The incidence of symptomatic ARIA-E was 2.8% in the lecanemab group and 0.0% in the placebo group. The ARIA-H (ARIA cerebral microhemorrhages, cerebral macrohemorrhages, and superficial siderosis) price was 17.0% in the lecanemab group and 8.7% in the placebo group. The incidence of symptomatic ARIA-H was 0.7% in the lecanemab group and 0.2% in the placebo group. There was no imbalance in remoted ARIA-H (i.e., ARIA-H in sufferers who didn’t additionally expertise ARIA-E) between lecanemab (8.8%) and placebo (7.6%). The complete incidence of ARIA (ARIA-E and/or ARIA-H) was 21.3% in the lecanemab group and 9.3% in the placebo group. Overall, the relative danger profile of ARIA for lecanemab was inside expectations
Clarity AD was a world confirmatory Phase 3 placebo-controlled, double-blind, parallel-group, randomized study in 1,795 individuals with early AD. The remedy group was administered lecanemab 10 mg/kg bi-weekly, with individuals allotted in a 1:1 ratio to obtain both placebo or lecanemab. The baseline traits of each placebo and lecanemab teams was comparable and nicely balanced. Eligibility standards allowed sufferers with a broad vary of comorbidities/comedications: hypertension, diabetes, coronary heart disease, weight problems, renal disease, anti-coagulants, and so forth. Eisai’s recruitment technique for the Clarity AD scientific trial ensured higher inclusion of ethnic and racial populations in the U.S., ensuing in roughly 25% of the entire U.S. enrollment together with Hispanic and African American individuals dwelling with early AD. Due to the inclusive eligibility standards and the profitable recruitment of various ethnic and racial populations in the U.S., Clarity AD’s inhabitants is mostly similar to the nation’s Medicare inhabitants.
“We are very excited about the great lecanemab Phase 3 results in early Alzheimer’s disease announced by our partner Eisai today. It brings hope to millions of people around the world who are fighting Alzheimer’s disease every day. The Clarity AD results fully meet all our expectations, both in terms of highly statistical significance and in the consistency over primary and all key secondary endpoints. This is a huge accomplishment by our employees and our partner Eisai who have worked tirelessly for almost two decades to make this project a success. We are proud that our founder Lars Lannfelt’s discoveries has the potential to fundamentally improve the treatment of Alzheimer’s disease, where there currently are very limited options,” stated BioArctic’s CEO Gunilla Osswald. “The results are also a confirmation of our technology platform and strengthens our hope to also be able to help improve the treatment of other neurodegenerative diseases such as Parkinson’s disease, ALS and others.”
In July 2022, the U.S. Food and Drug Administration (FDA) accepted Eisai’s Biologics License Application (BLA) for lecanemab below the Accelerated Approval Pathway and granted Priority Review. The Prescription Drugs User Fee Act motion date (PDUFA) is ready for January 6, 2023. The FDA has agreed that the outcomes of Clarity AD can function the confirmatory study to confirm the scientific advantage of lecanemab. In an effort to safe conventional FDA approval for lecanemab as quickly as potential, Eisai submitted the BLA by the FDA’s Accelerated Approval Pathway in order that the company might full its evaluate of all lecanemab information with the exception of the information from the confirmatory Clarity AD study.
In March 2022, Eisai started submitting software information, with the exception of Clarity AD information, to Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) below the prior evaluation session system with the purpose of acquiring early approval for lecanemab so that folks dwelling with early AD could have entry to the remedy as quickly as potential.
Eisai goals to file for conventional approval in the U.S., and to submit advertising and marketing authorization functions in Japan and Europe by the tip of the primary quarter 2023.

About lecanemab (BAN2401)
Lecanemab is an investigational humanized monoclonal antibody for Alzheimer’s disease (AD) that’s the results of a strategic analysis alliance between BioArctic and Eisai. Lecanemab selectively binds to neutralize and eradicate soluble poisonous Aβ aggregates (protofibrils) which are thought to contribute to the neurodegenerative course of in AD. As such, lecanemab could have the potential to impact disease pathology and to decelerate the development of the disease. Currently, lecanemab is being developed as the one late-stage anti-Aβ antibody that can be utilized for the remedy of early AD with out the necessity for titration, enabling full remedy impact from day one.
The Clarity AD open-label extension is underway with remedy initiated after completion of the Core interval to additional consider the security and efficacy of lecanemab. In addition, the lecanemab Phase 3 scientific study AHEAD 3-45 is ongoing for people with preclinical (asymptomatic) AD, that means they’re clinically regular and have intermediate or elevated ranges of mind amyloid. AHEAD 3-45 is performed as a public-private partnership between the Alzheimer’s Clinical Trial Consortium, funded by the National Institute on Aging, a part of the National Institutes of Health, and Eisai. In 2021, lecanemab was chosen for the Tau NexGen scientific study for Dominantly Inherited Alzheimer’s disease (DIAD), as a background anti-amyloid remedy when exploring mixture therapies with anti-tau therapies. The study, which is ongoing, is performed by Dominantly Inherited Alzheimer Network Trials Unit (DIAN-TU), led by Washington University School of Medicine in St. Louis. Furthermore, Eisai has carried out a lecanemab subcutaneous dosing Phase 1 study and the subcutaneous formulation is at the moment being evaluated in the Clarity AD open label extension study.
