General information about the use of Viltepso
- If your symptoms or health problems do not get better or if they become worse, call your doctor.
Viltepso's mechanism of action is to “hide” exon 53, causing cells to bypass this exon and permitting the remaining exons to fit together properly. This allows the body to form a shortened version of the dystrophin protein. Viltepso (viltolarsen) injection helps the body to make dystrophin, a protein found in muscle cells. Dystrophin helps to strengthen and protect muscles. When exons are missing, cells do not have the proper instructions to make dystrophin. Continue reading
The new drugs approved by the FDA for the treatment of Duchenne Muscular Dystrophy (DMD) are Amondys 45 (casimersen), Viltepso (viltolarsen), Vyondys 53 (golodirsen), Exondys 51 (eteplirsen), Elevidys (delandistrogene moxeparvovec), and Emflaza (deflazacort). They include antisense oligonucleotides, a glucocorticoid and a gene therapy.
Duchenne muscular dystrophy (DMD) is a genetic disease that causes progressive weakness, loss of motor function and damage to skeletal and heart muscles. DMD, which has no cure, primarily affects males starting in early childhood, usually between 2 and 3 years of age. Continue reading
The length of time it takes for Viltepso (viltolarsen) to work in Duchenne muscular dystrophy (DMD) is still being evaluated in an ongoing study. Small studies showed an increase in the dystrophin protein (a "marker") in the muscle cells of patients with DMD after 20 to 24 weeks. Researchers believe that this increase in dystrophin may predict a clinical benefit in patients, but that is not yet proven. Continue reading
