Pamrevlumab Duchenne Muscular Dystrophy

Slide 29

Affects ~1 in every 5,000 newborn boys About 20,000 children are diagnosed with DMD globally each year The fatal disease is caused by genetic mutations leading to the absence or defect of dystrophin, a protein necessary for normal muscle function. The absence of dystrophin results in muscle weakness, muscle loss, fibrosis, and inflammation Patients with DMD are often non-ambulatory before the age of 12, and their progressive muscle weakness may lead to serious medical problems relating to diminished function of respiratory and cardiac muscles DMD Background
