The ADCOMS is a composite score that comprises 4/14 items from the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), 2 items from the Mini Mental State Examination (MMSE), and all items from the Clinical Dementia Rating (CDR). Composite score is derived from the variables from the 12 items, and ranges from 0 to 1.97, where higher score means greater impairment. Change from baseline was analyzed using Bayesian analysis. Data presented are posterior mean and posterior standard deviation.
A TEAE is defined as an AE that emerged during treatment or within 90 days following the last dose of study drug, having been absent at pretreatment (Baseline) or reemerged during treatment, having been present at pretreatment (Baseline) but stopped before treatment, or worsened in severity during treatment relative to the pretreatment state, when the AE was continuous. A SAE is any untoward medical occurrence that at any dose: results in death; is life-threatening (that is, the participant is at immediate risk of death from the adverse event as it occurs, this does not include an event that, has it occurred in a more severe form or is allowed to continue, might have cause death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability or incapacity; is a congenital anomaly or birth defect (in the child of a participant who is exposed to the study drug).

Lecanemab is an investigational antibody being studied for the treatment of Alzheimer's disease, including early Alzheimer's disease and preclinical Alzheimer's disease. It is being developed by Biogen Inc. (BIIB) and is currently in Phase 3 clinical trials.
Lecanemab is a monoclonal antibody, indicated by its -mab suffix. It is designed to target amyloid beta, a protein that accumulates in the brains of people with Alzheimer's disease. By binding to amyloid beta, Lecanemab aims to clear these plaques and potentially slow disease progression.
Lecanemab is being developed by Biogen Inc., a biotechnology company traded on the NASDAQ under the ticker symbol BIIB. Biogen is conducting Phase 3 clinical trials to evaluate the safety and efficacy of Lecanemab in patients with early and preclinical Alzheimer's disease.
Lecanemab is in Phase 3 clinical development. It has received FDA designations including Priority Review, Fast Track, and Accelerated Approval, indicating its potential to address an unmet medical need in Alzheimer's disease. However, it remains investigational and has not yet been approved.
Lecanemab is being studied in several clinical trials. NCT03887455 is a Phase 3 study in early Alzheimer's disease with 1906 participants. NCT04468659 is a Phase 3 study in preclinical Alzheimer's disease with 1400 participants. NCT01767311, a completed Phase 2 study, enrolled 856 participants with Alzheimer's disease.
Yes, Lecanemab is also known as Lecanemab IV, referring to its intravenous route of administration. Both names refer to the same investigational drug being developed by Biogen for the treatment of Alzheimer's disease.
