SK Pharmteco and Genethon Advance DMD Gene Therapy with French Manufacturing Milestone

  • SK Pharmteco's French subsidiary Yposkesi has manufactured 20 batches of AAV8 micro-dystrophin for Genethon’s GNT-0004 DMD gene therapy, including 18 cGMP-compliant batches at a 400 L scale.
  • The collaboration supported the launch of a pivotal Phase III clinical trial in Europe and the UK, authorized by EMA and MHRA in 2025.
  • Long-term data from the ASGCT 2026 meeting showed sustained efficacy and favorable safety profile for GNT-0004 at two years post-treatment.

This collaboration highlights SK Pharmteco's growing role as a key player in viral vector manufacturing, particularly for complex AAV programs. The success of this partnership positions the company to support additional late-stage gene therapy programs in Europe and beyond, while Genethon's progress with GNT-0004 could set new benchmarks for DMD treatments.
