Billy's Hope by Justin Merriman

Billy Ellsworth, 15, of Kennedy Township, waits for numbing cream to take effect on his hands before receiving an experimental drug to treat his Duchenne Muscular Dystrophy, 

a rare genetic disorder that starves muscles of needed protein and confines most of its sufferers to wheelchairs by the time they reach their teenage years, 

at Children's Hospital of Pittsburgh of UPMC in Lawrenceville on June 22, 2016. He is enrolled in a clinical trial for the drug Eteplirsen, which his mother, Terri, credits with his relatively good condition compared to others his age with the same diagnosis. An FDA advisory committee voted not to approve the drug, and now the FDA is considering whether or not to grant the drug accelerated approval status.

 Dr. Hoda Zakaria Abdel-Hamid examines Billy before receiving an experimental drug treatment at Children's Hospital of Pittsburgh of UPMC.
