FDA Grants Orphan Drug Designation to Ractigen's RAG-21 for FUS-ALS
- The FDA has granted Orphan Drug Designation to Ractigen Therapeutics' RAG-21 for amyotrophic lateral sclerosis (ALS) treatment, specifically targeting the FUS subtype.
- RAG-21 is a small interfering RNA (siRNA) therapy designed to reduce toxic FUS protein production by targeting FUS mRNA transcripts in the central nervous system.
- Preclinical data suggests RAG-21 can mitigate motor neuron degeneration and improve outcomes for patients with FUS-ALS, a severe and rapidly progressing form of ALS.
- RAG-21 shares a similar administration method with Ractigen's RAG-17, which has shown promising early clinical data in SOD1-mutated ALS patients.
