Mechanism of action

CAEL-101 works by directly binding to transthyretin tetramers and stabilizing their native conformation, which prevents dissociation into monomers that would otherwise misfold and aggregate into amyloid fibrils. This mechanism halts the progression of transthyretin amyloidosis by reducing the formation of toxic amyloid deposits that damage tissues, particularly the heart and peripheral nerves. By stabilizing the protein rather than clearing existing amyloid, it addresses the root cause of disease progression.
