Biogen/Eisai’s phase 3 trial of lecanemab in MCI meet primary endpoint
Eisai (ESALY) and Biogen (BIIB) “announced positive topline results from Eisai’s large global Phase 3 confirmatory Clarity AD clinical trial of lecanemab, an investigational anti-amyloid beta protofibril antibody for the treatment of mild cognitive impairment due to Alzheimer’s disease, AD, and mild AD with confirmed presence of amyloid pathology in the brain.
#Lecanemab met the primary endpoint and all key secondary endpoints with highly statistically significant results.
#Eisai will discuss this data with regulatory authorities in the U.S., Japan and Europe with the aim to file for traditional approval in the US and for marketing authorization applications in Japan and Europe by the end of Eisai’s FY2022, which ends March 31, 2023.
Additionally, Eisai will present the Clarity AD study results on November 29, 2022, at the Clinical Trials on Alzheimer’s Congress, and publish the findings in a peer-reviewed medical journal. Lecanemab treatment met the primary endpoint and reduced clinical decline on the global cognitive and functional scale, CDR-SB, compared with placebo at 18 months by 27%, which represents a treatment difference in the score change of -0.45 in the analysis of Intent-to-treat population.
Starting as early as six months, across all time points, the treatment showed highly statistically significant changes in CDR-SB from baseline compared to placebo.
All key secondary endpoints were also met with highly statistically significant results compared with placebo.
Key secondary endpoints were the change from baseline at 18 months compared with placebo of treatment in amyloid levels in the brain measured by amyloid positron emission tomography, the AD Assessment Scale-cognitive subscale14, AD Composite Score and the AD Cooperative Study-Activities of Daily Living Scale for Mild Cognitive Impairment.”
ESALY last traded at $39.79. BIIB last traded at $197.50.
