NOTE: The task description references "NCT06563895" as an Alzheimer's disease trial, but this trial is actually for transthyretin (TTR) amyloidosis prevention — NOT Alzheimer's disease. This page documents the actual Acoramidis trials.
Acoramidis (formerly known as AG10, ALXN2060) is a near-complete (>90%) transthyretin (TTR) stabilizer developed by Eidos Therapeutics, a BridgeBio company. It is designed to mimic the protective properties of the naturally occurring TTR T119M mutation, which prevents TTR from dissociating and forming amyloid deposits.
Acoramidis is being developed for the treatment of TTR amyloidosis, including:
Acoramidis binds to the thyroxine binding site on the TTR tetramer, stabilizing the native tetrameric structure and preventing dissociation into monomers — the rate-limiting step in TTR amyloidogenesis.
| Field | Value |
|---|---|
| Trial ID | NCT06563895 |
| Phase | Phase 3 |
| Sponsor | Eidos Therapeutics (BridgeBio) |
| Status | RECRUITING |
| Enrollment | 582 (estimated) |
| Start Date | May 12, 2025 |
| Primary Completion | October 2031 |
| Completion Date | December 2032 |
Study Design: Randomized, multicenter, double-blind, placebo-controlled, parallel-group, quadruple-masked Phase 3 trial for prevention in asymptomatic TTR variant carriers.
Primary Outcome: Time to development of ATTR (ATTR-CM or ATTR-PN, whichever occurs first, centrally adjudicated) over approximately 7 years.
Secondary Outcomes:
| Field | Value |
|---|---|
| Trial ID | NCT04839487 |
| Phase | Phase 3 |
| Sponsor | Eidos Therapeutics (BridgeBio) |
| Status | COMPLETED |
| Enrollment | 421 |
Results: Acoramidis resulted in a significantly better four-step primary hierarchical outcome containing components of mortality, morbidity, and function than placebo at 30 months in participants with ATTR-CM.
| Trial ID | Phase | Status | Indication |

| 2025 | ACT-EARLY prevention trial initiated |
Important Note: Despite the task description referencing an "Alzheimer's disease" trial, there is currently no registered ClinicalTrials.gov study investigating Acoramidis for Alzheimer's disease or any other CNS/neurodegenerative disease beyond TTR amyloidosis.

If an Acoramidis Alzheimer's disease trial exists, it would be either:
