Eisai (ESALY) and Biogen (BIIB) announced positive topline results from the Phase II study with BAN2401, an anti-amyloid beta protofibril antibody, in 856 patients with early Alzheimer’s disease.

The study achieved statistical significance on key predefined endpoints evaluating efficacy at 18 months on slowing progression in Alzheimer’s Disease Composite Score and on reduction of amyloid accumulated in the brain as measured using amyloid-PET. Topline results of the final analysis of the study demonstrated a statistically significant slowing of disease progression on the key clinical endpoint after 18 months of treatment in patients receiving the highest treatment dose as compared to placebo.

Results of amyloid PET analyses at 18 months, including reduction in amyloid PET standardized uptake value ratio and amyloid PET image visual read of subjects converting from positive to negative for amyloid in the brain, were also statistically significant at this dose. Dose-dependent changes from baseline were observed across the PET results and the clinical endpoints.

Further, the highest treatment dose of BAN2401 began to show statistically significant clinical benefit as measured by ADCOMS as early as 6 months including at 12 months. BAN2401 demonstrated an acceptable tolerability profile through 18 months of study drug administration.

The most common treatment emergent adverse events were infusion-related reactions and Amyloid Related Imaging Abnormalities. Infusion related reactions were mostly mild to moderate in severity. Incidence of ARIA-E was not more than 10% in any of the treatment arms, and less than 15% in patients with APOE4 at the highest dose per the study protocol safety and reporting procedures.

BIIB closed at $298.81, it last traded at $338. ESALY closed at $71.10.
