Head-to-head evidence
Lecanemab vs PMN310
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.

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.

PMN310
Developed by ProMIS Neurosciences, Inc.
No graded featured trial for this indication yet; the grade above reflects that absence, not a judgment.
