Head-to-head evidence
ALIA-1758 vs Lecanemab
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.
Alzheimer's Disease
Shared mechanism: Amyloid-beta (monoclonal antibody) · full Alzheimer's Disease pipeline
ALIA-1758
Developed by AbbVie
NCT06406348 · Phase 1 · completed
The trial was randomized and blinded against placebo, but it was conducted in healthy volunteers purely to check safety and dosing rather than cognitive or disease benefit, and no results have been posted yet.
Lecanemab · Leqembi
Marketed by Eisai and partners
NCT01767311 · Phase 2 · completed
Randomized, triple-masked phase 2b in early Alzheimer's disease (856 participants). The Bayesian primary analysis of the ADCOMS composite at 12 months estimated a 63.8% posterior probability of meaningful benefit for the highest dose, short of the study's prespecified success criterion, so the primary endpoint was not met.
Next expected readout: December 2026 · NCT06602258 (registry estimate)
