Head-to-head evidence
Lecanemab vs SHR-1707
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.

SHR-1707
Developed by Jiangsu Hengrui Pharmaceuticals
NCT05681819 · Phase 1 · completed
The trial randomized 33 participants to SHR-1707 or placebo with triple-blinding, a design able to isolate a genuine drug effect, but its primary outcomes were safety measures rather than a cognitive or functional efficacy endpoint, and results have not yet been posted, so no effect on Alzheimer's disease could be established from this record.
