Reviewable change
back to reviewVerubecestat (BACE1 inhibitor) Phase III EPOCH trial in mild-moderate AD halted for futility; cognitive worsening signal observed. Production-side amyloid intervention failed alongside MAb clearance approaches, narrowing therapeutic-window viability of the amyloid hypothesis.
This is a proposal, not yet accepted frontier state. It names what it would change and who proposed it. Only an accepted review event, signed under reviewer authority, writes it into the frontier. Until then it carries no authority over the record.
Proposed change
reason
Verubecestat EPOCH (Egan et al., NEJM 2018) and APECS were halted for futility, establishing BACE1 inhibition as a failed translation arm. The failed-trial finding is well-supported. Agent-drafted accept; eligible for human re-review.

vf_3d380bcccbe5850eThe diff is computed against current frontier state, the same diff a reviewer reads before deciding.
The live diff is computed from a writable workspace. This frontier is read-only here, so the change is shown as recorded without a recomputed before / after.
Canopus treats material changes like reviewable requests: one bounded packet, check output, reviewer decision, and accepted frontier effect.
Anti-amyloid translation in Alzheimer's disease receives a reviewable source, finding, caveat, replication, evaluation, or proof-affecting edit.
The packet names affected record objects, evidence, rationale, reviewer-facing fields, and expected proof impact.
Schema, provenance, benchmark, contradiction, and proof checks decide whether the request is ready to read.
A steward accepts, rejects, caveats, revises, or retracts the request under an inspectable identity.
Only the accepted event mutates frontier state. Atlases, constellations, and search update from that record state.
