Eteplirsen is a prescription medicine used to treat Duchenne muscular dystrophy (DMD). DMD is a rare genetic disorder that causes muscle weakness and loss of muscle function over time. Eteplirsen works by increasing the production of dystrophin, a protein that helps support muscle cells and helps maintain muscle function. This medicine is given as an intravenous (IV) infusion every week.
Eteplirsen (brand name Exondys 51) is a medication used for a very specific genetic disorder. Here's a breakdown of the key points:
Function:
- Eteplirsen is a gene therapy medication used to treat Duchenne muscular dystrophy (DMD) caused by a specific genetic mutation.
- Duchenne muscular dystrophy is a rare inherited condition that causes progressive muscle weakness. It occurs when there is a mutation in the gene that codes for a protein called dystrophin, which is critical for muscle function.
- Eteplirsen works by targeting this specific mutation and enabling the production of a shortened but functional form of dystrophin protein in muscle cells. This can help slow down muscle degeneration and improve muscle function.
Genetic Condition:
- Eteplirsen is only approved for treating DMD caused by exon 51 skipping mutations. Exons are parts of genes that code for protein instructions. In this case, exon 51 skipping refers to a mutation that prevents this specific exon from being included in the final protein product, leading to a non-functional dystrophin protein.
Administration:
- Eteplirsen is delivered through intravenous (IV) infusion every other week.
Benefits:
- Eteplirsen can help slow down muscle decline and improve muscle function in some patients with DMD caused by exon 51 skipping mutations. This may translate to improved mobility, ambulation, and respiratory function.
Important Considerations:
- Eteplirsen is only effective for DMD caused by the specific exon 51 skipping mutation. Genetic testing is required to confirm eligibility for this medication.
- Gene therapy is a relatively new field of medicine, and the long-term effects of Eteplirsen are still being studied.
- Eteplirsen can cause side effects like fever, vomiting, and headache.
