FDA Grants Breakthrough Therapy Designation to Avidity's Del-zota for Duchenne Muscular Dystrophy
- The FDA has granted Breakthrough Therapy designation to delpacibart zotadirsen (del-zota) for treating Duchenne muscular dystrophy in patients with mutations amenable to exon 44 skipping.
- Del-zota demonstrated statistically significant increases in exon skipping, substantial dystrophin production increases, and significant creatine kinase reduction to near-normal levels in Phase 1/2 trials.
- Avidity Biosciences remains on track for a planned Biologics License Application submission at year-end 2025, with topline data from the ongoing Phase 2 extension trial expected in Q4 2025.
- The therapy represents a novel Antibody Oligonucleotide Conjugate approach that combines monoclonal antibody specificity with oligonucleotide precision to deliver treatment directly to muscle tissue.
