Sarepta Therapeutics has completed a new drug submission to the FDA in the United States for Casimersen, their third exon-skipping medicine for individuals with Duchenne amenable to exon 45.

• Casimersen is designed for the treatment of exon 45 amenable patients, approximately eight percent of patients with Duchenne.
• Casimersen is the third exon-skipping medicine using the Company’s proprietary PMO RNA-based platform.

Interim analysis from their ESSENCE trial demonstrated a statistically significant increase in dystrophin compared to baseline and placebo.
