Pipeline – Elritercept

Overview1,2

Elritercept is designed to bind to and block downstream signaling of select TGF-β superfamily ligands, including Activin A/B and GDF8/111,2

Mechanism of Action1,2

  • Elritercept binds to Activin A/B and GDF8/11, thereby preventing their binding to Activin/TGF-β pathway receptors and inhibiting downstream signaling, resulting in rebalanced pathways1,2
