Summary

Dirucotide (MBP8298) is a synthetic myelin basic protein peptide fragment investigated as a disease-modifying agent for secondary progressive multiple sclerosis (SPMS). It aimed to induce immune tolerance against myelin antigens. Phase III trials (MAESTRO-03) failed to meet primary endpoints, halting further development.

Mechanism of Action

Dirucotide is a synthetic peptide corresponding to residues 82–98 of human myelin basic protein (MBP82-98). It induces antigen-specific T-cell tolerance by promoting anergy or apoptosis of autoreactive T-cells that target myelin, thereby reducing inflammatory demyelination in multiple sclerosis.
