Duchenne Muscular Dystrophy Clinical Trials

RGX-202 is a gene therapy designed to deliver a transgene for a novel microdystrophin that includes functional elements of naturally-occurring dystrophin including the C-Terminal (CT) domain. This is a multicenter, open-label dose evaluation clinical study to assess the safety, tolerability and clinical efficacy of a one-time intravenous (IV) dose of RGX-202 in participants with Duchenne.

This project will systematically plan and evaluate the implementation of the Transdiagnostic Sleep and Circadian Intervention for youth (TranS-CY). As an early stage study, investigators will focus on recruitment strategies to reach the target population and collection of preliminary data on primary and secondary effects of the TranS-CY. Weekly remote (video web conferencing) parent training sessions will allow investigators to explore adoption through parent adherence and examine whether the essential elements of the TranS-CY intervention (e.g., motivational interviewing, goal setting, problem solving, sleep routine scheduling, monitoring) can be consistently taught by clinicians and implemented by parents into the home setting.

The purpose of this study is to understand the safety and effects of an experimental gene therapy called fordadistrogene movaparvovec. We are seeking participants from previous Pfizer interventional studies. We will follow participants' experience in this study for 10 years after the end of their previous study. Participants will have 1 annual onsite visit and a few annual remote visits. The exact number of remote visits will be decided by their study doctor. Read Less

The study objective is to identify the earliest changes in energy substrate metabolism in patients with cardiomyopathies (CMP). To achieve this objective, we plan first to test the hypothesis that patients with CMP present focal alterations in myocardial hyperpolarized [1-13C]pyruvate flux. Read Less

This project will assess the vascular responsiveness in leg muscles of boys with Duchenne muscular dystrophy (DMD) to one single dose of tadalafil, a common vasodilator drug, using non-invasive techniques (MRI or Doppler ultrasound) and exercise testing. These findings will provide proof of concept for a subsequent intervention study to demonstrate efficacy of longer-term tadalafil to counter sympathetic vasoconstriction and slow disease progression in DMD. It will also inform whether a group of patients do not respond to the drug. Read Less

ARISE is a prospective and longitudinal clinical study of individuals with Duchenne Muscular Dystrophy (DMD) aimed at creating a database of functional motor abilities in this population to support validation efforts of the Duchenne Video Assessment (DVA). Read Less

CureDuchenne link is a data hub comprised of integrated biospecimens, clinical data, and self- and/or caregiver-reported information from participants. Anyone over 4 weeks old who has been diagnosed with DMD or BMD or who is a carrier of DMD or BMD can join. Parents or legal guardians can sign up their child(ren). Read Less

The purpose of this non-interventional study is to evaluate the feasibility of remotely administering the North Star Ambulatory Assessment (NSAA) to participants with Duchenne muscular dystrophy (DMD). The iTakeControl (iTC) software platform will be utilized to remotely administer and score the NSAAs. Read Less

Current methods of measuring the response to new treatments for muscular dystrophies involve the examination of small pieces of muscle tissue called biopsies. The investigators are interested in finding less invasive methods that reduce the need for muscle biopsies. The purpose of this research is to learn about the possibility of detecting and measuring the activity and severity of muscular dystrophies by examining a urine sample and a blood sample. Read Less

Current methods of measuring the response to new treatments for muscular dystrophies involve the examination of small pieces of muscle tissue called biopsies. The investigators are interested in finding less invasive methods that reduce the need for muscle biopsies. The purpose of this research is to learn about the possibility of detecting and measuring the activity and severity of muscular dystrophies by examining a urine sample and a blood sample, and some muscles in the arms and legs using tests called ultrasound and electrical impedance myography; both tests are painless and non-invasive. The information that is gathered from this study may help to evaluate, prevent, diagnose, treat, and improve the understanding of human muscle diseases. Read Less

The hypothesis tested here is that a lower dose of intermittent oral corticosteroids (5mg/kg/week) will be equally effective to the 10mg/kg/week dose. Read Less

The Duchenne Registry is an online, patient-report registry for individuals with Duchenne and Becker muscular dystrophy and carrier females. The purpose of the Registry is to connect Duchenne and Becker patients with actively recruiting clinical trials and research studies, and to educate patients and families about Duchenne and Becker care and research. At the same time, The Duchenne Registry is a valuable resource for clinicians and researchers in academia and industry, allowing access to de-identified datasets provided by patients and their families-information that is vital to advances in the care and treatment of Duchenne. The Duchenne Registry is a member of the TREAT-NMD Neuromuscular Network. Read Less
