简要总结
The purpose of this low interventional study is to collect data on everyday movement in boys with Duchenne muscular dystrophy (DMD) using wearable activity sensors. The activity sensors could provide useful information beyond what is currently collected by functional (movement, strength) assessments in clinic. This information can help with the understanding of the impact of DMD, and perhaps with how possible treatments can affect this impact.

入选标准
- •Diagnosis of Duchenne muscular dystrophy confirmed by medical history and genetic testing
- •Body weight between 15 and 50 kg
- •Receipt of glucocorticoids for 6 months and a stable daily dose for at least 3 months prior to study entry
- •Ability to rise from floor within seven (7) seconds and ability to walk
排除标准
- •Current exposure to systemic immunosuppressant agents other than glucocorticoids.
- •Prior exposure to any gene therapy agent, including exon-skipping and missense agents.
- •Exposure to other investigational drugs within 30 days or 5 half-lives, whichever is longer.
- •Any injury which may impact functional testing per investigator's judgement. Previous injuries must be fully healed prior to consenting. Prior lower limb fractures must be fully healed and at least 3 months from injury date at screening.
- •Any planned surgeries which may impact physical activity and performance.
- •Presence or history of musculoskeletal or neurological disease in addition to DMD.
- •Any known allergies or skin reactions to stainless steel, versaflex, and silicon that may cause possible discomfort by wearable sensors.
- •Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, cancer, autoimmune or allergic disease that may interfere with the study conduct as per investigator's judgment, excluding untreated, asymptomatic, seasonal allergies at time of screening.
- •Investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or participants who are Pfizer employees, including their family members, directly involved in the conduct of the study.
