Eisai Co., Ltd. announced an article about long-term health outcomes of its investigational anti-amyloid-beta protofibril antibody lecanemab in people living with early Alzheimer’s disease (AD) using simulation modeling was published in a peer- reviewed journal Neurology and Therapy.

In this simulation, lecanemab treatment is estimated to potentially slow the rate of disease progression, maintaining treated patients for a longer duration in earlier stages of mild cognitive impairment (MCI) due to AD and mild AD (collectively, early AD).

The article describes the comparison of the long-term clinical outcomes for the people living with early AD who have amyloid pathology with standard of care (SoC) alone (including stable use of acetylcholinesterase inhibitor or memantine), and with lecanemab with SoC (lecanemab+SoC), using the disease simulation model (AD ACE model,) based on the results of a Phase IIb clinical trial (Study 201) evaluating the efficacy and safety of lecanemab. SoC data were estimated from ADNI (Alzheimer's Disease Neuroimaging Initiative) study results. It was shown that the estimated lifetime risk of disease progression to mild, moderate, and severe AD dementia from baseline could potentially be reduced by 7%, 13% and 10% in lecanemab+SoC, respectively, compared to SoC.

In the model the mean time advancing to mild, moderate, and severe AD dementia was longer for patients in the lecanemab-treated group than for patients in the SoC group by 2.51 years (SoC vs. lecanemab+Soc: 3.10 vs.5.61 years), 3.13 (6.14 vs. 9.27 years) and 2.34 (9.07 vs.11.41 years) respectively. Subgroup analysis by age and disease severity at baseline also revealed a potentially greater impact on disease progression with earlier initiation of treatment with lecanemab. The incremental mean times for transition to mild and moderate AD dementia were 2.53 and 3.34 years, respectively, when treating MCI due to AD in a subgroup analysis compared to SoC.
