HPLC Method for Analysis of Eteplirsen on Primesep B Column

Separation type: Liquid Chromatography Mixed-mode

Eteplirsen (brand name Exondys 51) is an antisense oligonucleotide used for the treatment of some types of Duchenne muscular dystrophy (DMD), a rare genetic disorder characterized by progressive muscle degeneration and weakness. Eteplirsen specifically targets patients who have a confirmed mutation of the DMD gene that is amenable to exon 51 skipping.

Approval: Eteplirsen was granted accelerated approval by the U.S. Food and Drug Administration (FDA) in 2016. This approval was based on an increase in dystrophin protein in skeletal muscle observed in some patients treated with Eteplirsen. The FDA has required the manufacturer to conduct a clinical trial to confirm the drug’s clinical benefit.

Administration: Eteplirsen is administered as an intravenous infusion.

Chemical Structure: Eteplirsen is an oligonucleotide, a short sequence of nucleic acids. Its full chemical structure is detailed and specific, given its nature as an oligonucleotide.

Safety and Efficacy: Common side effects include balance disorder and vomiting. The clinical benefit of Eteplirsen, including improved motor function, has not been definitively established.
