Overview

DYNE-401 is an investigational drug being developed by Dyne Therapeutics for the treatment of Pompe disease (Glycogen Storage Disease Type II). It is a next-generation enzyme replacement therapy that utilizes Dyne’s proprietary FORCE platform to deliver acid alpha-glucosidase (GAA) specifically to muscle tissue. The drug is a conjugate targeting both transferrin receptor protein 1 (TfR1) and GAA, aiming to enhance delivery and uptake into muscle cells. Mechanistically, DYNE-401 acts as a transferrin receptor protein 1 (TfR1) antagonist and an acidic alpha-glucosidase inhibitor, designed to address the underlying enzyme deficiency in Pompe disease by improving cellular uptake of GAA. As of March 2025, DYNE-401 remains in preclinical development[1][3].
